    Opinion for the court per curiam.
    Opinion by Associate Judge GLICKMAN, concurring in part and dissenting in
    part, at page 213.
    PER CURIAM:              After a nine-month jury trial, the six appellants in this case
    were convicted of conspiracy and a string of violent crimes, including homicides,
    that were committed in connection with their membership in a gang known as the
    22nd Street Crew. They raise numerous challenges to their convictions in these
    consolidated appeals. With a few exceptions, however, we affirm the judgments of
    the Superior Court.

    XI.   Conclusion ............................................................................................................212
    The government presented evidence at appellants‘ trial showing that there was
    a criminal street gang operating in the area of 22nd Street, Southeast, Washington,
    D.C. The investigation of this gang revealed a violent, drug-trafficking organization
    functioning in the blocks of 22nd Street that sat between Southern Avenue and
    Savannah Street, and influencing areas around the gang‘s base of operations. The
    5
    goals of the organization were centered on the purchase, storage, packaging, and
    resale for profit, of illegal drugs within the community.
    Members of the gang committed numerous criminal acts in an effort to
    protect the territory of the gang and integrity of its operations. This misconduct
    took the form of acts of violence designed to safeguard the organization. Often,
    the violence was directed at perceived rivals who might threaten the gang‘s
    territory and drug trade or witnesses who might undermine its operations through
    cooperation with law enforcement.
    The gang was called various names, including the ―22nd Street Crew,‖ ―The
    Deuce,‖ ―Deuce-Deuce,‖ ―Shipley Market,‖ ―Young Gunz,‖ and ―Deuce Squad
    Mafia.‖ For simplicity, it will be referred to in this opinion as the ―22nd Street
    Crew.‖ The 22nd Street Crew had a loose rank structure wherein members would
    play different roles according to the level of authority and respect they had gained
    over time through demonstrations of loyalty to the gang.        Members that had
    achieved a sufficient level of respect would be referred to as ―OGs‖ or ―original
    gangsters.‖ More junior members were labeled ―baby gangsters‖ or ―little locs.‖
    6
    The government‘s evidence tended to demonstrate the involvement of all six
    appellants in the 22nd Street Crew. Lannell Cooper had been part of the 22nd
    Street Crew since the 1990s and achieved an unmatched level of authority within
    the gang. Michael Tann was part of the gang for a similar period and was close
    behind Cooper in the hierarchy. James Rushing, Dajuan Beaver, and Antonio
    Arnette carried less weight in the organization; however, evidence was presented
    showing their long-standing involvement in the 22nd Street Crew and its operation.
    Saquawn Harris was a newer member, having been introduced by another high-
    ranking gang member.
    The indictment in this case charged the six appellants with conspiracy and
    with committing serious acts of violence as part of their participation in the 22nd
    Street Crew. Specifically, the indictment articulated that each appellant entered
    into a conspiracy to ―knowingly and willfully . . . agree together to obstruct justice
    and to assault and kill anyone whose interests were contrary to those of
    [appellants] and their associates.‖   In a nine-month joint trial of appellants from
    November 2008 to July 2009, the government endeavored also to show that four
    murders were committed, as part of the charged conspiracy, at or near 22nd Street
    between 2003 and 2006. The government contended that these murders were
    7
    directed toward maintaining the turf and authority of the 22nd Street Crew, either
    by eliminating perceived rivals or killing government witnesses. Each appellant
    was involved in at least one of these murders; appellant Tann was alleged to have
    played a role in three of the four. The essential facts of each major incident are
    briefly recited here.
    I. The Leslie Jones Murder
    Leslie Jones was a drug dealer who sold his product near 22nd Street,
    specifically in the Shipley Market area. He had a long-running feud with Tann that
    revolved around competition for drug sales and a prior incident in which one of his
    relatives assaulted Tann and had stolen his weapon.
    On the evening of April 11, 2003, Tann attended a small party with his
    future wife Tracey at his cousin‘s house in Southeast, Washington, D.C. At some
    point during the evening, Tann told Tracey that he was going to 22nd Street and
    left the party.   Tann found Leslie Jones at a pay phone near Shipley Market and
    shot him from behind. 22nd Street Crew member Alphonce Little was an
    eyewitness to the murder. Another witness, Tyrone Curry, heard the gunfire and
    saw Tann running away from the scene of the crime. Tann later confessed to
    8
    Tracey, and another 22nd Street Crew member named Donald Matthews, that he
    had committed the murder.
    II. The Terrence Jones Murder and Richard Queen Assault
    The murder of Terrence Jones on April 17, 2004, began with an argument on
    22nd Street between gang member Donald Matthews and a 22nd Street resident,
    Kyara Johnson, apparently about the type of liquor that was to be served at Kyara‘s
    birthday party. The verbal quarrel threatened to become violent before it was
    broken up by Kyara‘s sister, Shaunta Armstrong. Shaunta called her close friend
    Terrence Jones and asked him to come to 22nd Street to make sure that the
    situation was under control. Terrence Jones went to 22nd Street with his friend,
    Richard Queen. Terrence Jones approached Matthews and had a brief conversation
    with him. Matthews explained that he ―just had an argument [with Kyara] but it
    wasn‘t nothing.‖ Witnesses reported that their interaction ended peacefully and
    without incident.
    According to Kyara Johnson, appellant Arnette learned of the exchange
    between Donald Matthews and Terrence Jones and yelled, ―Doe‖ [referring to
    appellant Cooper] Kyara heard Cooper respond, ―Where at?‖ Shaunta Armstrong
    9
    then heard someone (believed to be Cooper) ask, ―Squirt [appellant Arnette‘s
    nickname], who‘s faking?‖ Arnette nodded in the direction of Terrence Jones and
    Richard Queen and told Cooper to go up the street with his ―hammer,‖ which was
    the street name for a gun. Cooper approached Terrence Jones and pointed a gun at
    him while Arnette hit Terrence Jones with his hands. Then, according to several
    witnesses, Cooper said words to the effect of ―Pat them niggers‘ pockets.‖
    Arnette proceeded to pat Terrence Jones‘s pockets and hit him in the face.
    Witnesses stated that at some point Terrence Jones resisted by hitting Cooper, and
    Cooper shot him in response. When Terrence Jones tried to crawl away, Cooper
    shot him again.
    Witnesses further testified that at approximately the same time as Terrence
    Jones was under attack, appellant Tann and other unidentified males appeared,
    pinned Richard Queen against a car, and began beating him and going through his
    pockets. According to Donald Matthews, Tann picked up a gun off the ground in
    the midst of the fight with Queen and shot him in the back as he tried to run away,
    wounding Queen but not badly enough to prevent his escape. Several days later,
    Tann told Matthews that he had shot Queen. At trial, Queen testified that his
    assailants had stolen cash and cigars that he was carrying that night.
    10
    III. The James Taylor Murder and Bernard Mackey Assault
    A third murder occurred on 22nd Street a little over two years later, in the
    early evening of May 4, 2006.        Again, the events were precipitated by an
    argument. This time it was a disagreement between Omar Harrison and Ashley
    Tyndle during which Harrison may have struck Tyndle. Harrison was an outsider
    to 22nd Street, and Tyndle was the girlfriend of gang member Alphonce Little.
    As the dispute climaxed, Harrison made reference to his lack of fear of Little
    by telling Tyndle to ―go get your baby[‘s] father‖ or words to that effect. At the
    time of the argument between Harrison and Tyndle, various members of the 22nd
    Street Crew were dispersed in different places on 22nd Street; one witness testified
    that one ―little crew,‖ including appellants Tann and Harris, as well as Little and
    several other gang members, was gathered near a basketball court. When word of
    the Harrison-Tyndle dispute, and Harrison‘s challenge to Little, spread by word of
    mouth to the gang, Little, Harris, Tann, and other gang members raced toward
    Harrison from different directions on 22nd Street.
    11
    Then, multiple witnesses saw Harris and Tann open fire at Omar Harrison.
    Seven witnesses testified that they saw Harris shooting. Four witnesses saw Tann
    shooting. One witness testified that between five and ten gang members were
    shooting en masse with Tann and Harris although this testimony was conflicting.
    Two witnesses testified to seeing gang member Antonio Blaylock with a gun
    drawn during the incident. According to another witness, ―a lot of people‖ in
    addition to Tann and Harris were shooting.
    Alphonce Little, who denied firing a weapon, stated that immediately after
    the first waves of gunfire ended, he heard a separate set of gunshots coming from
    another location ―across the street.‖ These shots were fired by Robert Foreman,
    who Little testified was a very junior member of the 22nd Street Crew. Foreman
    saw and heard Tann and Harris firing at Harrison, felt compelled to join in the
    attack, and started shooting as well.
    Once the firing started, Omar Harrison jumped into his truck and drove away
    safely. However, James Taylor, a 22nd Street resident who had been standing near
    Harrison‘s truck, was hit by a bullet in the head and died.    Bernard Mackey,
    12
    another innocent bystander, was also standing nearby and was grazed by a bullet in
    the back.
    Alphonce Little ran with appellant Harris to the house of Harris‘s girlfriend
    and watched him pack his bags in preparation to go into hiding. Robert Foreman
    found Harris and Little at Harris‘s girlfriend‘s house. Little testified that Foreman
    told Harris and Little that he believed he had fired the shot that killed James
    Taylor. There was no evidence to show that either Harris or Tann, although aware
    of each other‘s role in the shooting and the presence of other gang members during
    the event, knew of Foreman‘s involvement in the murder. Following the incident,
    Harris fled the area and lived in disguise for several weeks until his arrest.
    IV. The Laquanda Johnson Murder and Keisha Frost Assault
    Notably for purposes of this appeal, appellant Cooper was tried for and
    convicted of the murder of Terrence Jones in 2006. At the time of the instant
    2008-2009 trial of the appellants in this case, Cooper was serving a lengthy prison
    sentence for that crime. At Cooper‘s 2006 trial, the government listed Kyara
    Johnson and her older sister, Laquanda Johnson, as potential witnesses. Kyara
    testified about Cooper‘s shooting of Terrence Jones following her argument with
    13
    Matthews. Laquanda was not an eyewitness to the Terrence Jones murder;
    however, Cooper had made several incriminating statements to her in the aftermath
    of that incident. Ultimately, Laquanda did not testify at the 2006 trial, but she
    could be seen at the courthouse during the trial supporting her sister. Laquanda
    was protective of her younger sister and was known by reputation to be a
    ―gatekeeper‖ for those seeking access to Kyara.
    Cooper was convicted at the end of June 2006. Approximately two weeks
    later, in the early morning of July 11, 2006, the sisters (who had been relocated
    from 22nd Street because of Cooper‘s trial) returned to 22nd Street to visit friends.
    Appellant Beaver saw the sisters and told Alphonce Little that they were back.
    Little investigated their presence and confirmed that the sisters were hanging out at
    a 22nd Street house with Keisha Frost, Laquanda Johnson‘s friend.         Beaver and
    Little met with Dwayne Wright, another 22nd Street Crew member.            The three
    men discussed the sisters and agreed that they ―got to go‖ – meaning that they
    should be killed – because of their cooperation with the government. Beaver and
    Little further discussed which one of them was going to do the killing.       Beaver,
    arguing that he had already done his duty to the gang by testifying in Cooper‘s
    defense at his 2006 trial, persuaded Little that he had an obligation to eliminate the
    14
    Johnson sisters. Wright retrieved a gun for Little, and Beaver gave Little a pair of
    sunglasses as a partial disguise. Preparations were completed when Little secured
    a ―hoodie‖ from Robert Foreman, and an escape route from appellant Rushing,
    who agreed to drive Little and Beaver away from the scene of the anticipated
    shooting.
    Alphonce Little walked up to the house where he had seen the Johnson
    sisters. Kyara Johnson was inside, but Laquanda was on the porch with Keisha
    Frost. Little opened fire and shot both women, believing that Keisha was Kyara.
    Laquanda died, but Keisha lived. Kyara, looking out of an upstairs window,
    witnessed the shooting. Little ran away from the scene toward 23rd Street and
    Southern Avenue.     Rushing collected Little and Beaver in his car and instructed
    Little to get rid of the hoodie. Beaver directed the gang members to his mother‘s
    house in Maryland where he hid the gun that Dwayne Wright had given Little to
    commit the murder.
    15
    V. Obstruction of Justice – Witness Intimidation and Manipulation
    In the aftermath of these incidents, several appellants, and other gang
    members, approached witnesses in efforts to prevent their cooperation with law
    enforcement. Karen Bolling, the mother of Laquanda and Kyara Johnson, testified
    that while appellant Cooper was still on the street, he approached Laquanda and
    offered her drugs and money if she would keep Kyara off the stand during his 2006
    trial for the murder of Terrence Jones.
    After his arrest, Cooper sent out overtures from prison to numerous
    individuals in an effort to have them persuade (by force if necessary) the Johnson
    sisters and others not to testify against him. Cooper reached out to members of an
    allied street gang on 17th Street, including Brian Gilliam and Tyrell Hargraves, to
    have them search 22nd Street for Kyara. Gang member Travis Honesty and gang
    ally Dewey Chappell also testified that Cooper, from jail, instructed them and
    others (including appellants Tann, Beaver, Harris, Rushing, and gang member
    Alphonce Little) to find the sisters at various points. Karen Bolling also testified
    that after Cooper was arrested, Laquanda implored her not to let Kyara testify
    against Cooper, explaining that Tann had ―talked to [Cooper]‖ and that ―[Cooper]
    wanted to know was [Laquanda] going to help him by not letting her sister testify.‖
    16
    Tann approached other witnesses after the James Taylor-Bernard Mackey
    incident. He threatened Zartia Anderson, the sister of witnesses to the James
    Taylor murder, and stated that he was going to ―straighten things out‖ regarding
    their cooperation with the government. Tann also confronted Donnise Harris,
    another James Taylor murder witness, and urged her to testify falsely that appellant
    Harris (no relation to Donnise Harris) had not been involved in the incident.
    VI. Procedural Developments
    A grand jury investigating these criminal activities in the area of 22nd Street
    handed down its original indictment in September 2007. A second grand jury
    followed with a superseding indictment in February 2008. The superseding
    indictment charged appellants with conspiring ―to obstruct justice and to assault
    and kill anyone whose interests were contrary to those of [appellants] and their
    associates,‖ and numerous crimes related to that overall conspiracy, including
    involvement in the four murders described above.        The jury returned general
    17
    verdicts against all six appellants, finding each guilty of conspiracy.1 In addition,
    each appellant was convicted on multiple other counts, as follows:
    Tann was convicted of first-degree premeditated murder while armed2 of
    both Leslie Jones and James Taylor, second-degree murder while armed3 of
    Terrence Jones, armed robbery4 and assault with intent to kill while armed5
    (―AWIKWA‖) of Richard Queen, AWIKWA of Bernard Mackey, two counts of
    obstruction of justice,6 one count of threatening a person,7 and a host of weapons
    offenses8 related to these underlying crimes. Harris was convicted of first-degree
    premeditated murder while armed of James Taylor, AWIKWA of Bernard
    Mackey, and several related weapons offenses. Beaver was convicted of first-
    1
    D.C. Code § 22-1805a (2012 Repl.).
    2
    D.C. Code §§ 22-2101, -4502 (2012 Repl.).

    8
    D.C. Code § 22-4504 (a), (b) (2012 Repl.).
    18
    degree premeditated murder while armed of Laquanda Johnson, assault with a
    dangerous weapon9 (―ADW‖) of Keisha Frost, and obstruction of justice, carrying
    a pistol without a license, unlawful possession of a firearm in connection with that
    event.       He was also convicted of an additional count of obstruction of justice
    related to his prior attempts to influence the testimony of the Johnson sisters.
    Cooper was convicted of first-degree premeditated murder while armed of
    Laquanda Johnson and ADW of Keisha Frost on a conspiracy theory of liability
    pursuant to Pinkerton v. United States, 
    328 U.S. 640
    (1946).          He was also
    convicted on two counts of obstruction of justice related to the Johnson sisters and
    several weapons offenses.        Rushing was convicted of first-degree premeditated
    murder while armed of Laquanda Johnson, ADW of Keisha Frost, and obstruction
    of justice and weapons offenses related to that shooting. Finally, Arnette was
    convicted of second-degree murder while armed of Terrence Jones, armed robbery
    of Richard Queen, and weapons offenses related to that incident.
    Appellants followed with these appeals. In our discussion of their manifold
    claims of error, we first analyze the claims relating to the sufficiency of the
    government‘s evidence. Next, we deal with procedural and evidentiary issues
    9
    D.C. Code § 22-402 (2012 Repl.).
    19
    affected by the alleged conspiracy and flowing from appellants‘ joint trial. Then,
    we address pretrial and trial matters not directly tied into the conspiracy or
    appellants‘ joinder. We conclude with our merger analysis and instructions to the
    trial court upon remand.
    VII. Claims Concerning the Sufficiency of the Evidence
    A. Conspiracy
    Appellants argue that the evidence failed to establish their membership in
    the single conspiracy charged by the superseding indictment.10          Instead, they
    contend, the evidence merely established, at best, only several short-term and
    discrete conspiracies, and the trial judge erred in failing to grant their motions for
    judgment of acquittal (―MJOA‖) as to the conspiracy count. ―The standard by

    appellants‘ claims, we will consider the sufficiency of the evidence as to the
    membership of each defendant in the single conspiracy charged by the indictment.

    The superseding indictment charged that between April 2003 and July 2006,
    appellants and others conspired as follows:
    [D]efendants Lannell N. Cooper . . . Stephen R. Gray . . .
    Michael D. Tann . . . Antonio D. Arnette . . . Saquawn L.
    Harris . . . Robert J. Foreman . . . Brian K. Gilliam . . .
    Dwayne A. Wright . . . James E. Rushing . . . [and
    Dajuan D. Beaver],[11] and other persons whose identities
    are both known and unknown to the grand jury, did
    knowingly and willfully combine, conspire, confederate,
    and agree together to obstruct justice and to assault and
    kill anyone whose interests were contrary to those of the
    defendants and their associates, in violation of 22 D.C.
    Code Sections 401, 402, 722, 2101.
    11
    The charges against appellant Beaver were included in the original
    September 2007 indictment, but were not included in the superseding indictment
    issued in February 2008. Prior to trial in this case, the government moved to rejoin
    Beaver with the other appellants and the motion was granted by the trial court.
    The cases against Dwayne Wright, Robert Foreman, Brian Gilliam, and Stephen
    Gray, all alleged coconspirators and 22nd Street Crew members or allies, were
    voluntarily severed from appellants‘ joint trial by the government.
    22
    The indictment proceeded to list thirty-three discrete overt acts, twenty-seven of
    which went to the jury, alleged to have been committed by at least one charged or
    uncharged coconspirator.
    Because of the way that the indictment alleged the conspiracy, we review the
    sufficiency of the evidence to examine whether it properly established that each
    appellant knowingly participated in an agreement to obstruct justice, or to assault
    or kill anyone whose interests were contrary to those of the defendants and their
    coconspirators,12 and whether at least one overt act was committed by a
    coconspirator. At trial, the government offered testimony about the structure and
    operations of the 22nd Street Crew through several gang ―insiders‖ who testified as
    cooperating witnesses: former gang members Andre McDuffie, Devin Evans,
    Donald Matthews, and Alphonce Little. Their testimony tended to demonstrate
    that the gang had a geographical territory around 22nd Street where only
    authorized members were permitted to sell illegal drugs. In order be part of the
    22nd Street Crew and enjoy the privileges associated with that membership, such
    12
    See White v. United States, 
    714 A.2d 115
    , 119 n.5 (D.C. 1998) (―Since
    the jury returned a general verdict of guilty on the charge . . ., the conviction may
    be affirmed if the evidence was sufficient to support either theory.‖).
    23
    as the right to partake in the profits of the gang‘s drug trafficking business,
    members had to be willing to further the common goals of the gang through the use
    of violence. McDuffie testified that to sell drugs as a member of the 22nd Street
    Crew:
    You have to commit acts of violence; you have to stay
    loyal to one another; you got to help each other, if you
    need anything [like] guns or if you need more drugs. It‘s
    a commitment. It‘s like a way of life.
    Appellants and other gang members used violence to protect their territory
    and to silence or retaliate against those who were believed to threaten the business
    and security of the gang and its operations.        Devin Evans testified that an
    ―outsider‖ was ―considered somebody that‘s not from your neighborhood,
    somebody that‘s not welcomed‖ who would be ―dealt with [by] acts of violence‖ if
    caught acting in a way adverse to the business interests of the crew. Andre
    McDuffie further explained: ―[W]e had to enforce that no one can come into our
    area and try to take over our territory; no one can come in there and sell drugs
    [because] we wasn‘t having it.‖ If an outsider tried to move in on the gang‘s drug
    market, McDuffie stated, ―[The outsider] would have a problem [and] may end up
    losing [his life.]‖   Donald Matthews testified similarly. When asked what would
    happen if people from another part of the city ―decided to set up shop and sell
    24
    drugs‖ on 22nd Street, Matthews replied ―[t]hey wouldn‘t last long‖ because gang
    members would ―[r]un them away‖ using ―[v]iolence.‖
    The gang members treated ―snitches,‖ meaning those ―cooperating, telling
    authorities . . . about the activities of our organization,‖ in the same way.
    McDuffie testified that if someone was to cooperate with the government, ―there
    would be violence inflicted.‖
    The gang members played different roles in the operation according to the
    ―different rank[s] and level[s] of respect‖ that members had earned over time
    through demonstrations of loyalty to the gang. Donald Matthews testified that the
    different roles assigned to gang members included selling drugs, storing money,
    stealing cars, and ―committ[ing] acts of violence in order to protect the
    neighborhood.‖ However, Andre McDuffie also testified that ―everyone was an
    enforcer,‖ willing to handle a ―beef‖ with ―rival[s] in the street. The cooperating
    witnesses also revealed how 22nd Street Crew members shared weapons, warned
    each other about police activity in the gang‘s, and provided assistance to gang
    members who were in jail.
    25
    Such testimony sufficiently showed that no matter what role was played by a
    particular gang member at a given time, the 22nd Street Crew members were
    required to support the use of violence in order to advance the overall goals of
    maintaining the stability and reputation of the organization, its territory, and its
    illegal drug business. This testimony also established that the gang operated as a
    cohesive unit (albeit loosely coordinated), with a rank and leadership configuration
    that bound the gang together.
    This testimony was the backdrop with which the jury examined the
    participation of appellants in the charged conspiracy and the facts of the murders in
    this case. The following subsections detail the evidence that more specifically
    demonstrated the knowing participation of appellants in the conspiracy alleged.
    1. Antonio Arnette
    Donald Matthews testified that appellant Antonio Arnette was a member of
    the 22nd Street Crew. According to Matthews, Arnette spent considerable time
    with appellants Cooper, Rushing, and fellow gang member Alphonce Little, on
    22nd Street. Matthews testified that Arnette was also involved with other 22nd
    Street Crew members in packaging and selling illegal drugs in areas commonly
    used by the gang. Two other gang ―insiders,‖ Devin Evans and Alphonce Little,
    also testified that Arnette was a member of the 22nd Street Crew. Little testified
    26
    that Arnette sold drugs on 22nd Street and sometimes carried a gun. Several police
    officers also testified that they observed Arnette trafficking illegal drugs in the
    presence of other gang members and in areas known to belong to the 22nd Street
    Crew.
    Arnette also played a leading role in the attack on Terrence Jones and
    Richard Queen. The evidence about this incident reasonably showed that Arnette
    perceived that Terrence Jones and Queen affronted the territory of the 22nd Street
    Crew by confronting fellow gang member Donald Matthews on the gang‘s turf.
    Arnette then called out Terrence Jones and Richard Queen for ―faking‖ on 22nd
    Street, identified the two outsiders to Cooper (who Arnette knew was a leading
    member of the gang), and recommended that Cooper ―bring his hammer‖ to deal
    with the situation.   And the facts showed that Cooper (and Tann) responded
    accordingly, in reliance on Arnette‘s representations, resulting in a chain of events
    that led to Terrence Jones‘s death and Queen‘s shooting.
    Although Arnette and Cooper may have been mistaken about whether
    Terrence Jones or Richard Queen was a true threat to the interests of the 22nd
    Street Crew, the evidence was sufficient to show that Arnette and Cooper believed
    27
    that the outsiders, who they thought were ―faking‖ by challenging Donald
    Matthews, had territorial aspirations adverse to the interests of appellants and their
    22nd Street Crew associates. The evidence surrounding this incident, especially in
    the context of Arnette‘s active membership in the 22nd Street Crew and its illegal
    activities, was sufficient to demonstrate his knowing participation in an agreement
    with Cooper and other gang members ―to assault and kill‖ those whose goals were
    contrary to those of the gang.
    2. Dajuan Beaver
    Appellant Beaver was identified by Devin Evans, Donald Matthews, and
    Alphonce Little as a member of the 22nd Street Crew who sold illegal substances
    with other gang members on 22nd Street. Alphonce Little also testified that he
    shared weapons with Beaver and that Beaver carried a gun.
    Beaver also played a role in the crimes against the Johnson sisters, who were
    known by the gang members to be government cooperators. Beaver was involved
    in assisting Cooper with his attempt to alter Kyara‘s testimony in the period
    leading up to his trial. Moreover, Beaver was a key player in Laquanda Johnson‘s
    murder. Beaver found the Johnson sisters on 22nd Street the evening of the
    murder, convinced Alphonce Little to murder them in retaliation for their
    28
    cooperation with the government in Cooper‘s 2006 trial, and then assisted Little by
    helping him put together a disguise before the shooting and covering up the crime
    afterward. The evidence was clear that Beaver was motivated to aid in this crime
    because of his membership in the 22nd Street Crew and his belief that the
    objectives of the membership were contrary to those of ―snitches.‖ Thus, the
    evidence was sufficient to show Beaver‘s knowing participation with other gang
    members in a conspiracy to ―obstruct justice and to assault and kill‖ persons with
    aims contrary to those of his codefendants.
    3. Lannell Cooper
    Government witnesses testified that appellant Cooper was a long-standing
    and high-ranking member of the organization who by 2004 ―could tell everybody
    [in the gang] what to do.‖ He was also deeply involved in the illegal drug trade on
    22nd Street. Cooper was a principal in the murder of Terrence Jones for perceived
    threats to the gang‘s reputation and territory on 22nd Street. And he was the
    instigator of a series of attempts to obstruct justice with regard to the cooperation
    of the Johnson sisters with the government in his 2006 prosecution – attempts
    which were ultimately connected to Laquanda Johnson‘s murder by Alphonce
    Little. Clearly, the evidence was sufficient to show his knowing participation in an
    agreement with other members of the 22nd Street crew to commit obstruction of
    29
    justice and murder of individuals possessing interests conflicting with those of the
    gang.
    4. Saquawn Harris
    Alphonce Little testified that appellant Harris was a member of the 22nd
    Street Crew, although he was a newer member of the gang who had been
    introduced to the gang and encouraged to sell drugs on 22nd Street by influential
    gang member Eric Dreher. Little further stated that he sold illegal drugs with
    Harris and shared weapons with him. The testimony of several police officers
    bolstered Little‘s testimony about Harris‘s connection to the 22nd Street Crew by
    establishing that Harris was seen regularly with Tann, Beaver, Arnette, Rushing
    and other gang members on 22nd Street.
    In light of these relationships, the James Taylor-Bernard Mackey incident
    was probative evidence of Harris‘s participation in the conspiracy. The facts of
    that incident showed that Harris, Tann, and many other gang members, responded
    to an insult by an outsider, Omar Harrison, to Alphonce Little‘s girlfriend on 22nd
    Street – in the heart of the gang‘s territory – and to Harrison‘s instruction to
    Little‘s girlfriend to ―go get your baby[‘s] father.‖ Harris and Tann opened fire in
    the direction of Omar Harrison in a sequence of events that resulted in the death of
    30
    James Taylor and the wounding of Bernard Mackey. Like the Terrence Jones-
    Richard Queen incident, Harris‘s active participation in an event where he
    violently reacted to a perceived threat to the reputation of the gang (and to the
    girlfriend of a fellow gang member) was sufficient evidence of his knowing
    participation in an agreement ―to assault and to kill‖ those whose interests ran
    contrary to those of his gang associates.
    5. James Rushing
    Andre McDuffie testified that appellant Rushing had been a member of the
    22nd Street Crew since the early 1990‘s; McDuffie was a senior gang member at
    the time of Rushing‘s entry into the gang, and McDuffie was responsible for
    teaching Rushing gang-related skills. McDuffie also testified that he saw Rushing
    sell crack cocaine on a regular basis on 22nd Street. Matthews‘s testimony
    additionally provided supporting evidence of Rushing‘s drug trafficking activities
    with other members of the gang.
    Like Beaver, Rushing played a critical role in the Laquanda Johnson murder,
    which was evidence of his involvement in the conspiracy. Knowing that Little
    intended to murder the Johnson sisters because of their cooperation with the
    government, Rushing agreed to act as Little‘s getaway driver. Rushing drove
    31
    Little and Beaver from the scene of the crime after Little killed Laquanda and
    wounded Keisha Frost. He also helped Little cover up the crime by instructing him
    to discard his clothing, and by driving Little to Beaver‘s mother‘s house in
    Maryland where Beaver stashed the murder weapon. Given Rushing‘s participation
    in the Laquanda Johnson murder, the killing of a known government cooperator, in
    light of Rushing‘s relationship with the 22nd Street Crew and its members, the
    evidence was sufficient to show his knowing participation in the conspiracy ―to kill
    or assault‖ persons (such as Laquanda) whose interests were not aligned with those
    of Rushing or his associates.
    6. Michael Tann
    All of the government‘s ―insider‖ witnesses (McDuffie, Evans, Matthews,
    and Little), as well as Tracey Tann (appellant Tann‘s wife), testified that Tann was
    a well-known and high-ranking member of the 22nd Street Crew. Matthews and
    Little also provided testimony about Tann‘s participation with other gang members
    in the gang‘s drug trade.
    More than any other appellant, Tann was also closely involved in the acts of
    violence against outsiders who challenged the 22nd Street Crew‘s territory and
    reputation. Tann was a key player in the Leslie Jones, Terrence Jones, and James
    32
    Taylor murders. Moreover, the facts point to Tann‘s repeated use of threats of
    violence against potential witnesses, who might testify against his coconspirators,
    in order to obstruct justice. These circumstances were sufficient to establish that
    Tann – sometimes acting alongside other gang members to commit acts of violence
    against perceived rivals (including Terrence Jones and Omar Harrison) –
    knowingly joined and participated in an agreement ―to obstruct justice or assault or
    kill‖ persons whose interests ran counter to those of the gang.
    ***
    In sum, the evidence was sufficient to show that appellants, all members of
    the 22nd Street Crew, entered into an agreement to obstruct justice by threatening
    or manipulating witnesses, or to assault or kill persons whose interests were at
    odds with theirs, such as rivals or cooperating witnesses, and knowingly and
    voluntarily participated in that agreement. 
    Hairston, 905 A.2d at 784
    . Moreover,
    of the twenty-seven overt acts of the conspiracy that went to the jury, many were
    supported by sufficient evidence, and at least some were supported by
    overwhelming evidence.13 See Lumpkin v. United States, 
    586 A.2d 701
    , 703 (D.C.
    1991).
    13
    For example, the facts that went to Overt Acts 28-30, which described
    Little‘s murder of Laquanda Johnson and assault of Keisha Frost, were not in
    dispute.
    33
    As to appellant‘s arguments that the proof at trial did not show a single
    conspiracy, but instead showed that appellants merely engaged in ―discrete
    projects, which happened within a general community ethos,‖ and that the
    ―indictment was so broad and unlimited as to be meaningless in a criminal
    context‖, we find them unavailing. First, the evidence was sufficient to show that
    appellants were engaged in actions demonstrating a core common purpose, namely
    to inflict or threaten violence on rivals (real or perceived) and government
    cooperators. See United States v. Graham, 
    83 F.3d 1466
    , 1471-72 (D.C. Cir. 1996)
    (concluding that there was a single conspiracy where the court had ―no doubt that
    [the] evidence was sufficient for a reasonable juror to conclude that appellants and
    others shared the common goal of distributing crack cocaine for profit‖ despite
    evidence of multiple drug-dealing ―cliques‖ operating in a particular territory).
    Moreover, it is clear that the appellants and other gang members acted
    together, relied on each other, and often coordinated their efforts, in order to more
    effectively achieve their common goal of inflicting (or threatening) violence on
    those opposed to the interests of the gang. See United States v. Gatling, 
    96 F.3d 1511
    , 1522 (D.C. Cir. 1996) (finding ―interdependence‖ existing for purposes of a
    34
    single conspiracy even when assistance provided by coconspirators to each other is
    ―fairly minimal‖); see also United States v. Richerson, 
    833 F.2d 1147
    , 1154 (5th
    Cir. 1987) (―Parties who knowingly participate with core conspirators to achieve a
    common goal may be members of an overall conspiracy.‖). The events of the
    Terrence Jones murder-Richard Queen assault (involving Tann, Cooper and
    Arnette), the James Taylor murder-Bernard Mackey assault (involving Tann,
    Harris, and other gang members), and Laquanda Johnson murder-Keisha Frost
    assault (involving Beaver and Rushing), are examples of such coordinated actions
    by all appellants to achieve the goals of the conspiracy.
    Finally, we agree with the United States Court of Appeals for the District of
    Columbia Circuit that ―a conspiracy‘s purpose should not be defined in too narrow
    or specific terms.‖ 
    Gatling, 96 F.3d at 1520
    . Our case law demonstrates the same
    principle. See 
    Hairston, 905 A.2d at 784
    (conspirators‘ aim was to ―seek[] revenge
    against the 1400 block faction [of rival gang members]‖); 
    Castillo-Campos, 987 A.2d at 483
    (conspiracy‘s objective was ―to kill or otherwise ‗get‘ the rival gang
    members‖). Here, although the conspiracy to ―obstruct justice and to assault and
    kill anyone whose interests were contrary‖ to the gang was indeed a broadly stated
    criminal objective, appellants have not cited any authority demonstrating that the
    35
    conspiracy count as charged was legally deficient. Cf. United States v. Romero,
    
    897 F.2d 47
    , 51-52 (2d Cir. 1990) (affirming conviction for conspiring to kill a
    federal officer where defendants‘ conspiracy ―was the result of a plan agreed to by
    all the defendants to kill anyone posing a threat to them or [their narcotics]
    business‖).
    Instead, the conspiracy count adequately apprised appellants of the elements
    of the offense and the time frame within which the conspiracy existed, such that
    appellants could properly prepare their defenses and were protected against double
    jeopardy. See United States v. Roman, 
    728 F.2d 846
    , 853-54 (7th Cir. 1984)
    (indictment properly charged conspiracy where it alleged a conspiracy, the
    criminal statute violated, and the time frame of the conspiracy). Therefore, we
    grant no relief to appellants on the basis of their claims regarding the sufficiency of
    the evidence on, or the legality of, their conspiracy charges.
    B. Terrence Jones-Richard Queen Incident
    1. Tann’s Convictions: Second-Degree Murder While Armed of
    Terrence Jones, Armed Robbery and AWIKWA of Richard Queen, and
    Possession of a Firearm During the Commission of a Crime of Violence
    (“PFCV”)
    36
    Appellant Tann makes several sufficiency claims regarding his Terrence
    Jones-Richard Queen related convictions. Emphasizing heavily the testimony of
    Richard Queen and the lack of credibility of Donald Matthews, Tann challenges
    the identification evidence that the jury relied on for his involvement in the entire
    incident. Furthermore, he argues that, even if found to have been involved in the
    event, he did not possess the state of mind required for the jury to convict him
    under an aiding-and-abetting theory of liability for the second-degree murder while
    armed of Terrence Jones and related counts of PFCV.
    Tann‘s argument concerning the offenses in which he was the principal (the
    armed robbery of Richard Queen, AWIKWA of Queen, and related weapons
    offenses) is that the government‘s evidence was insufficient because it rested
    solely on a single, incredible witness: Donald Matthews. However, the testimony
    of a single witness is sufficient to sustain a conviction, even where contradicted by
    other witnesses or evidence. Gibson v. United States, 
    792 A.2d 1059
    , 1066 (D.C.
    2002). Although Matthews was not a perfect witness, the jurors credited his
    testimony and it was permissible for them to do so.14         We afford the jury‘s
    14
    Tann‘s best evidence to counter Matthews was the testimony of the
    surviving victim, Richard Queen, who testified that Tann was not among his
    attackers. While powerful counterevidence, the jury could have reasonably
    (continued…)
    37
    credibility determination substantial deference on appellate review.        (Steven)
    Robinson v. United States, 
    928 A.2d 717
    , 727 (D.C. 2007).
    Tann‘s other claims involve those crimes of which he was convicted on an
    aiding-and-abetting theory of liability (second-degree murder of Terrence Jones
    and related PFCV offenses). Because he was convicted of second-degree murder
    for aiding and abetting Cooper‘s shooting of Terrence Jones, the government was
    required to prove that Tann had, at a minimum, a ―depraved heart‖ with regard to
    Terrence Jones‘s death. 
    Perez, 968 A.2d at 102
    (―For second-degree murder, the
    intent required is malice, which can be proven by evidence of a specific intent to
    kill, specific intent to inflict serious bodily harm, or wanton and willful disregard
    of an unreasonable human risk – also known as ‗depraved heart‘ murder.‖).
    ―[W]here a specific mens rea is an element of a criminal offense, a defendant must
    have had that mens rea himself to be guilty of that offense, whether he is charged
    as the principal actor or as an aider and abettor.‖ Kitt v. United States, 
    904 A.2d 348
    , 356 (D.C. 2006); see also Coleman v. United States, 
    948 A.2d 534
    , 552-53
    (…continued)
    concluded that Queen, who was attacked from behind during an extremely chaotic
    situation, simply was unable to view and identify all of the men who were involved
    in the attack.
    38
    (D.C. 2008) (extending the doctrine that the aider and abettor must share in the
    mens rea of the principal to second-degree murder).
    Tann portrays his attack on Richard Queen as separate and distinct from
    Cooper‘s and Arnette‘s attack on Terrence Jones; further, Tann claims that there
    was no evidence that he knew Cooper was going to shoot Terrence Jones or that he
    helped Cooper with the shooting. To be sure, there was no evidence of any pre-
    attack discussion or coordination between Tann, Cooper, and Arnette in which the
    gang members explicitly identified Terrence Jones‘s death as a goal.
    However, the government had powerful evidence of a joint and coordinated
    effort, and of Tann‘s ―depraved heart,‖ through testimony that as the attack was
    escalating, Cooper ordered Arnette, Tann, and others, to rob Terrence Jones and
    Richard Queen – an order which was carried out by its recipients. This was done
    when Cooper directed his cohorts to ―Pat them niggers‘ pockets.‖ The evidence
    was not perfectly clear to whom this order was issued and precisely when Cooper
    said it in the course of events; however, a fair interpretation of the evidence
    suggests that it was made by Cooper to both Arnette (who was covering Terrence
    Jones) and the men (including Tann) who were attacking Queen.
    39
    This understanding of the evidence was bolstered by testimony that
    Cooper‘s instructions were immediately carried out by Tann, Arnette, and others,
    with regard to both Terrence Jones and Richard Queen. The close proximity of the
    attack on Terrence Jones and the attack on Queen, a matter of approximately ten
    feet according to witnesses, in conjunction with these robbery instructions,
    sufficiently proved that the attacks were a knowingly organized (if not verbally
    articulated) venture designed to allow Tann and his fellow gang members tactically
    to divide their victims in order to better subdue, rob, and eventually shoot both of
    them. Moreover, the jury could have easily inferred from the close proximity of
    the assaults that as Tann attacked Queen, he saw Cooper (a man by reputation
    known to have a history of violence) striking Terrence Jones and pointing a gun at
    him.
    Given these circumstances, it was reasonable for the jury to have found that
    Tann displayed a ―wanton and willful disregard of an unreasonable human risk‖ to
    the life of Terrence Jones when he isolated, neutralized, robbed, and ultimately
    shot the man who he knew was in a position to come to Terrence Jones‘s aid:
    40
    Richard Queen. See (Darion) Ingram v. United States, 
    40 A.3d 887
    , 900-01 (D.C.
    2012); 
    Perez, 968 A.2d at 102
    .
    Analyzing Tann‘s PFCV offenses associated with Cooper‘s murder of
    Terrence Jones, our case law instructs that ―[w]hen the government relies on an
    aiding and abetting theory to prove PFCV, it is not enough to show that the
    defendant participated ‗in the ―larger scheme‖ of the [crime].‘‖ Fox v. United
    States, 
    11 A.3d 1282
    , 1287 (D.C. 2011) (quoting Lancaster v. United States, 
    975 A.2d 168
    , 175 (D.C. 2009)). ―Rather, the government must prove some act on the
    defendant‘s part that assisted the [principals] in their possession of firearms . . . .‖
    
    Fox, 11 A.3d at 1287
    (internal quotation marks and emphasis omitted). Tann‘s
    case is distinguishable from cases such as Fox and Lancaster where we found
    PFCV offenses insufficient in the aiding-and-abetting context.
    By complying with Cooper‘s directive to rob Richard Queen, the jury could
    have found that Tann assisted Cooper in maintaining possession (by preventing
    Queen from coming to the aid of his friend) of the firearm that he was using in the
    course of the murder of Terrence Jones. The facts show that Tann took affirmative
    steps to help Cooper keep possession of his firearm by subduing Queen in a
    41
    number of ways: (1) patting Queen‘s pockets – at Cooper‘s direction; (2) striking
    Queen; (3) robbing Queen; (4) and ultimately shooting Queen as he ran for safety
    where he could have called for help for Terrence Jones. Furthermore, the fact that
    Terrence Jones resisted Cooper by hitting him suggested that Tann‘s actions
    toward Queen were helpful in ensuring that Queen could not aid Jones in further
    interfering with Cooper‘s possession of the weapon. Dang v. United States, 
    741 A.2d 1039
    , 1043 (D.C. 1999).
    The facts of Dang, where we found that the evidence was sufficient to show
    that appellant aided and abetted his codefendants in the possession of their
    firearms, are very similar to the facts here. In Dang, although the defendant did
    not possess a weapon, the evidence demonstrated that he ―worked in concert with
    [his codefendants] by, among other things, blocking the door, guarding [one
    victim] and pointing a knife at [a second victim].‖ 
    Id. Here, like
    in Dang, Tann
    helped Cooper maintain possession of his weapons through his actions, working in
    concert with those of Cooper, to neutralize Richard Queen.
    Therefore, we reject in their entirety Tann‘s arguments challenging the
    sufficiency of the evidence for his convictions related to the Terrence Jones-
    Richard Queen incident.
    42
    2. Arnette’s Convictions: Second-Degree Murder While
    Armed of Terrence Jones, Armed Robbery of Richard Queen,
    and PFCV
    Like Tann, appellant Arnette argues that the evidence was insufficient as to
    the mens rea elements required for his Terrence Jones murder-Richard Queen
    assault related convictions. The government pursued each of the counts in the
    indictment against Arnette related to this incident under an aiding-and-abetting
    theory of liability.
    Kyara Johnson testified that Arnette initiated the attack by calling for
    Cooper and telling him to confront Terrence Jones and Richard Queen while
    armed, i.e., with his ―hammer.‖ Kyara also testified that Arnette patted Terrence
    Jones‘s pockets, at Cooper‘s command, and struck him with his hands while
    Cooper had his gun drawn. Certainly, if believed, this would amount to active
    participation in the assault on Terrence Jones. However, as Tann does, Arnette
    argues that his involvement in the offense did not demonstrate the necessary state
    of mind for second-degree murder because he had no reason to believe that Cooper
    would shoot Terrence Jones. Also like Tann, Arnette relies on the fact that there
    was no previous conversation with Cooper about intending to kill Terrence Jones
    or any evidence that Arnette did anything to encourage Cooper to do so. Instead,
    43
    he argues that the shooting was a ―spontaneous reaction by Cooper‖ to Terrence
    Jones‘s unexpected resistance to the attack.
    Arnette further argues that the evidence is even more attenuated, and
    therefore also insufficient, regarding his convictions for aiding and abetting Tann
    in the armed robbery of Richard Queen. He claims that there is no reasonable
    inference to be drawn from his actions toward Terrence Jones (patting his pockets
    and/or hitting him) that supports the notion that he shared in Tann‘s intent to rob
    Queen.
    The government witnesses against appellant Arnette were often inconsistent
    and sometimes exculpatory in their testimony. However, the question here is
    whether, viewing the evidence in the light most favorable to the government,
    Arnette‘s conduct demonstrated the ―depraved heart‖ (if not a more criminally
    culpable) state of mind required for the second-degree murder of Terrence Jones,
    the specific intent to commit armed robbery of Queen, and knowledge of Cooper‘s
    and Tann‘s use of firearms, as well as assistance to Cooper and Tann in
    maintaining possession of those firearms, as required by the associated PFCV
    offenses. The key facts, as to the offenses involving both victims, were: (1)
    44
    Arnette instigated the entire event by identifying Terrence Jones and Richard
    Queen to Cooper and telling him that the two men were on 22nd Street ―faking‖;
    (2) Arnette instructed Cooper to ―bring his hammer,‖ meaning Cooper‘s gun,
    thereby anticipating and inciting violence; (3) Arnette complied with Cooper‘s
    order to pat Terrence Jones‘s pockets; (4) Arnette hit Terrence Jones in the course
    of the attack; (5) Tann violently assaulted Queen less than ten feet away from
    Arnette‘s and Cooper‘s attack on Terrence Jones; and (6) Cooper phrased his
    ―robbery‖ instruction in the plural, so Arnette would have known that there were
    two victims to be jointly controlled and subdued by the attackers.
    As to the offenses in which Arnette aided and abetted Cooper (second-
    degree murder and associated PFCV offenses), the evidence against Arnette was
    clearly sufficient. See (Darion) 
    Ingram, 40 A.3d at 900-01
    ; 
    Perez, 968 A.2d at 102
    . Arnette‘s instigation of the violent attack on Terrence Jones and his active
    assistance during its undertaking demonstrated, at a minimum, a ―wanton and
    willful disregard of an unreasonable human risk.‖        
    Perez, 968 A.2d at 102
    .
    Moreover, the PFCV convictions underlying the Terrence Jones offenses were also
    based on sufficient evidence given that Arnette himself instructed Cooper to bring
    his gun to confront Terrence Jones and Richard Queen – obviously demonstrating
    45
    the requisite awareness and knowledge of Cooper‘s use of a firearm.          Then,
    Arnette took steps to assist Cooper in maintaining possession of the firearm during
    Cooper‘s attack on Terrence Jones. See 
    Fox, 11 A.3d at 1287
    ; 
    Lancaster, 975 A.2d at 175
    ; 
    Dang, 741 A.2d at 1043
    .
    For the robbery conviction of which Arnette was an accomplice to Tann, the
    government was required to show that Arnette had the specific intent to aid and
    abet Tann in the robbery of Richard Queen. Lattimore v. United States, 
    684 A.2d 357
    , 359-60 (D.C. 1996). Certainly, there was no evidence of a pre-attack
    discussion outlining robbery as a goal of the attack which would have made the
    government‘s case clear-cut.      Arnette relies on a Virginia case, McMorris v.
    Commonwealth, 
    666 S.E.2d 348
    , 352 (Va. 2008), for the proposition that
    ―[r]obbery is not an incidental, probable consequence of an assault; robbery
    requires a completely different type of wrongdoing: stealing.‖ Indeed, a joint
    assault plus close proximity to a codefendant‘s robbery may be insufficient to
    show specific intent to commit robbery under an aiding-and-abetting theory of
    liability. But the facts here are not so limited.
    46
    As we have already discussed, between the first stages of the attack and
    Tann‘s subsequent robbery of Richard Queen, Cooper issued his robbery
    instructions. And Cooper phrased his instructions in the plural: ―Pat them niggers‘
    pockets.‖   These instructions were followed by Arnette‘s patting of Terrence
    Jones‘s pockets, which could have been reasonably interpreted as a robbery
    attempt by Arnette on Jones. The fact that Arnette heard and executed Cooper‘s
    instructions strongly implied that Arnette knew exactly what Tann (one of the
    other recipients of Cooper‘s instructions) was similarly doing to Queen, and
    Arnette was intentionally aiding and abetting the robbery of Queen through his
    actions containing and subduing Terrence Jones. Again, it was reasonable for the
    jury to have viewed the entire attack (including the robbery) as a coordinated
    venture among Cooper, Tann, Arnette, and others, in which the gang members
    worked together, at Cooper‘s direction, to make their attack on both victims more
    successful through combined efforts. See Downing v. United States, 
    929 A.2d 848
    ,
    862 (D.C. 2007) (defendant‘s presence at the scene of a crime plus conduct which
    facilitates a crime supports an inference of guilt as an aider and abettor). So
    viewed, the evidence was legally sufficient for the jury to find that Arnette
    possessed the state of mind necessary for the second-degree murder of Terrence
    47
    Jones, the robbery of Richard Queen, and the PFCV offenses associated with
    Cooper‘s murder of Jones.
    However, the analysis is different as to Arnette for the ―armed‖ component
    of the robbery of Richard Queen and the related PFCV offense. Unlike Cooper‘s
    robbery instructions, which put Arnette on notice that Queen was about to be
    robbed, there was no similar mechanism by which Arnette was put on notice that
    Queen was about to be robbed by the use of a firearm. There is no evidence that
    Tann was in possession of a weapon prior to the point when Donald Matthews saw
    Tann pick up a gun from the ground during the melee and immediately use it to
    shoot Queen. Although arguably Arnette should have anticipated or foreseen that
    Tann would use a weapon, especially in light of Arnette‘s statement to Cooper that
    Cooper should bring his weapon, recent case law from the Supreme Court, as well
    as this court, teaches that foreseeability alone is insufficient to support such a
    judgment of conviction under an aiding-and-abetting theory of liability.
    In order to convict of an offense requiring the use of a firearm by a principal,
    the government must prove that the aider and abettor knew in advance that his
    associate was armed with a gun – enabling the defendant to ―make the relevant
    48
    (and indeed, moral) choice‖ to aid and abet an armed offense. Rosemond v. United
    States, 
    134 S. Ct. 1240
    , 1249 (2014) (―[A]n unarmed accomplice cannot aid and
    abet a [PFCV-type] violation unless he has foreknowledge that his confederate will
    commit the offense with a firearm.‖) (internal quotation marks omitted); (Leon)
    Robinson v. United States, No. 11-CF-1443, slip op. at 21 (D.C. Sept. 25, 2014)
    (―A person cannot intend to aid an armed offense if she is unaware a weapon will
    be involved.‖). Here, there was insufficient evidence that Arnette had advance
    knowledge that Tann was armed during the robbery of Richard Queen.
    Under these circumstances, the mere proximity of Arnette to Tann was not
    enough to infer such knowledge. The evidence showed that Tann picked up a
    firearm and used it to rob and shoot Richard Queen quite late in the timeline of the
    incident, giving Arnette no meaningful notice (if any at all) that Tann was going to
    use the gun to effectuate his attack on Queen. Cf. 
    Rosemond, 134 S. Ct. at 1250
    n.9 (―Of course, if a defendant continues to participate in a crime after a gun was
    displayed or used by a confederate, the jury can permissibly infer from his failure
    to object or withdraw that he had such knowledge.‖).
    49
    Had there been some evidence from which the inference could be drawn that
    Arnette had advance knowledge that Tann was using a gun to carry out the
    robbery, as well as evidence that Arnette assisted Tann in maintaining possession
    of the firearm, and decided to proceed with his involvement in the attack on
    Terrence Jones and Queen, our conclusion would be different. However, we see
    insufficient evidence based on this record. See Rivas v. United States, 
    783 A.2d 125
    , 134 (D.C. 2001) (en banc) (―[I]f the evidence, when viewed in the light most
    favorable to the government, is such that a reasonable juror must have a reasonable
    doubt as to the existence of any of the essential elements of the crime, then the
    evidence is insufficient and we must say so.‖) (internal quotation marks omitted).
    Therefore, we vacate the judgment as to the ―armed‖ component of
    Arnette‘s robbery conviction and his PFCV conviction associated with the robbery.
    The lesser-included offense of unarmed robbery, and all of Arnette‘s other
    convictions related to this incident are affirmed.15
    15
    See (Leon) Robinson, No. 11-CF-1443, slip op. at 37-38 (permitting the
    government to ―accept[] the entry of judgment for [the] lesser-included unarmed
    offense‖ of unarmed robbery after holding that the trial court committed
    instructional error, but concluding that the error did not affect the jury‘s findings
    on the elements of the lesser-included offense). Here, there has been no claim of
    instructional error with regard to the jury instruction concerning the state of mind
    required for conviction of PFCV under an aiding-and-abetting theory of liability.
    (continued…)
    50
    C. James Taylor-Bernard Mackey Incident
    Appellants Tann and Harris challenge the sufficiency of the evidence for
    their convictions based on the James Taylor and Bernard Mackey incident.
    Fundamentally, their claims turn on how the law of aiding and abetting is to be
    applied to the facts of this event. In addition to their sufficiency arguments,
    appellants raise two related claims, one regarding the aiding-and-abetting
    instruction given to the jury, and another regarding the trial court‘s ―curtailment‖
    of their closing arguments. Since all of these arguments turn on whether the court
    properly decided the legal issue related to the theory of liability, they are all
    addressed here.
    (…continued)
    Therefore, despite the insufficiency of the evidence on the armed component of
    Arnette‘s robbery conviction and the associated PFCV offense, there was no
    reasonable possibility that the jury‘s permissible finding of the elements of
    Arnette‘s lesser-included offense of unarmed robbery of Richard Queen, or of his
    Terrence Jones murder-related offenses (resulting in three convictions for second-
    degree murder and associated PFCV offenses based on Cooper‘s use of a weapon),
    was affected. Cf. 
    id. at 37-42.
    As we did in (Leon) Robinson, we conclude that
    there is ―no unfairness that we can discern in reducing [Arnette‘s] conviction to
    [the] lesser included offense[]‖ because Arnette ―had full notice of [his] potential
    liability for the lesser crime[] and there is no indication that defense presentation
    would have been altered if the armed charges had been dismissed at the end of the
    government‘s case or if the trial court had instructed the jury on the lesser-included
    offense[].‖ 
    Id. at 38
    (internal quotation marks omitted) (quoting Allison v. United
    States, 
    409 F.2d 445
    , 451 (D.C. 1969)). See also Jackson v. United States, 
    940 A.2d 981
    , 996 (D.C. 2008) (remanding the case to the trial court with instructions
    to enter judgment of conviction on a lesser-included offense).
    51
    The government argued that there were three shooters within the group of
    gang members who raced toward Omar Harrison after his dispute with Alphonce
    Little‘s girlfriend, Ashley Tyndle, from different directions on 22nd Street:
    appellants Tann and Harris, as well as a third shooter, junior gang member Robert
    Foreman. But the government presented evidence that additional gang members
    were shooting as well. Latina Anderson testified that she saw between five and ten
    men, including gang members Tann, Harris, Little, and Blaylock, emerge from
    nearby ―cuts‖ and shoot at Harrison.16 Christina Anderson told the grand jury that
    she saw Tann and Blaylock shooting. Donnise Harris saw Tann, Harris, and ―a lot
    of people‖ running and shooting.     Thus, if credited, the testimony of several
    witnesses established that there were a number of 22nd Street Crew members at the
    scene of the crime moving toward Omar Harrison in a hostile manner and
    shooting.
    16
    Little and government witness Travis Honesty denied that Little was
    shooting, but Little testified that he would have been shooting if he had had a gun
    at the time. Firearms examiner Robert Harvey testified that there were ―three
    firearms that [he] kn[e]w of for sure[,]‖ but agreed that ―[t]here could have been
    more[.]‖
    52
    Furthermore, there was testimonial evidence – not really disputed on appeal
    – tending to show that Harris and Tann opened fire on 22nd Street with the intent
    to shoot Harrison and that they were each aware of each other‘s presence at the
    time of the shooting.   Anderson testified that some other shooters were standing
    within a few steps of Tann and Harris while they all were shooting, thus permitting
    an additional inference that Harris and Tann were aware of the presence and
    participation of other gang-member shooters. However, there appears to have been
    no evidence to suggest that either Harris or Tann was aware of the specific
    presence and participation of Foreman until after the incident was complete.
    Foreman was shooting from a different position on 22nd Street than either Harris
    or Tann. The testimony was that Foreman saw and heard Tann and Harris firing at
    Harrison, felt compelled to join in the attack, and started shooting as well. The
    evidence was ambiguous as to which of the shooters, Harris, Tann, Foreman, or
    someone else, actually fired the shot or shots that hit James Taylor and Bernard
    Mackey.
    There was at least some evidence to show, primarily through the testimony
    of Alphonce Little, that James Taylor was not killed until after Harris‘s gun ran out
    of bullets and he stopped firing at Omar Harrison. Based on his statements to his
    53
    fellow gang members, Robert Foreman appeared to believe, or want others to
    believe, that his shot hit Taylor.
    The forensic evidence was of limited value. Although it was clear that
    James Taylor had been killed by a gunshot wound to the head, the fatal bullet
    passed through him and was not identified during the investigation. Therefore,
    there was no link between the fatal bullet and a particular gun or shooter;
    additional forensic evidence was of minimal weight in identifying the actual killer,
    and the government essentially conceded this at trial. The evidence was even less
    clear with regard to Bernard Mackey. No evidence was presented linking the
    bullet that grazed Mackey with any particular shooter.
    The government charged Harris and Tann with the premeditated murder of
    James Taylor and AWIKWA of Bernard Mackey. It told the jury they could
    convict Harris and Tann of Taylor‘s murder and (using transferred intent) of
    Mackey‘s assault either as principals or based on an aiding-and-abetting theory of
    liability.
    54
    Because the government did not know who fired the fatal shot, and also did
    not contend that Harris and Tann knowingly or intentionally associated themselves
    with Robert Foreman in particular at the time of the shooting,17 it argued that,
    regardless, aiding-and-abetting liability rendered each one criminally responsible
    for the others‘ actions if they all aided in the commission of the offense by firing at
    Omar Harrison.
    Harris and Tann contended that accomplice liability requires proof that the
    defendant was ―consciously helping the person that was the principal‖ (whom, they
    argue, the jury could have found to be Robert Foreman). According to appellants‘
    brief on appeal, to convict Harris and Tann of aiding and abetting Foreman‘s
    crime, the jury was required to find ―beyond a reasonable doubt that [appellants
    were] aware of Mr. Foreman‘s presence and aware that by firing first, they would
    cause Mr. Foreman to commit the acts that would result in the decedent‘s death.‖
    After litigating the issue, the trial court agreed with the government that if
    ―you can show that the person aided and abetted the crime itself[,] you‘ve solved
    17
    The government did, however, remind the court of evidence that showed
    that ―this is not a situation where Mr. Harris didn‘t know Mr. Foreman. There is
    evidence that these two men shared guns together, and that Mr. Foreman was a
    member of the conspiracy.‖
    55
    the intent problem.‖ Accordingly, the judge gave the pattern instruction for aiding
    and abetting, which does not reference intentional association with the principal.
    In relevant part, the instruction reads: ―To find that a defendant aided and abetted
    in committing a crime, you must find that the defendant knowingly associated
    himself with the commission of the crime, that he participated in the crime as
    something he wished to bring about, and that he intended by his actions to make it
    succeed.‖ Criminal Jury Instructions for the District of Columbia, No. 3.2 (5th ed.
    rev. 2013).   During closing arguments, the trial judge further informed the jury
    that there are two ―types‖ of aiding and abetting: ―if you knowingly aid and assist
    the [principal] . . . [or] if you knowingly aid and abet the crime.‖ In addition, the
    trial court instructed the jury that it is ―not the law‖ that ―‗[i]f you don‘t know who
    the shooter is or that they are present, you can‘t possibly be working together in a
    18
    coordinated effort‘ and ‗can‘t be an aider and abettor.‘‖
    On this issue, we find ourselves confronted with a very unusual fact pattern.
    There is no case in this jurisdiction that has addressed the legal viability of an
    aiding-and-abetting theory of liability as applied to a defendant whose actions
    18
    Nevertheless, Harris‘s counsel argued to the jury that, ―you can‘t help a
    crime that is occurring because some unknown person is committing that crime if
    you‘re unaware that that person is there.‖
    56
    actually aided the principal, and who possessed the same criminal intent as the
    principal, but who was unaware of the presence and participation of the principal at
    the time the criminal offense occurred. Because of the challenging nature of this
    issue, we pause to flesh out the arguments of the parties – neither of which we fully
    accept.
    1. The Government’s Argument
    The government‘s argument is that there are two manners in which a
    defendant in this jurisdiction can be guilty of aiding and abetting. One way is to
    aid and abet the principal offender in his or her commission of a crime. The other
    way is to ―advise,‖ ―incite,‖ or ―connive‖ at the offense itself, regardless of
    ―intentional association‖ between the principal and the aider and abettor. The
    government emphasizes the plain language of the aiding-and-abetting statute, D.C.
    Code § 22-1805 (2012 Repl.), which reads:
    In prosecutions for any criminal offense all persons
    advising, inciting, or conniving at the offense, or aiding
    or abetting the principal offender, shall be charged as
    principals and not as accessories, the intent of this section
    being that as to all accessories before the fact the law
    heretofore applicable in cases of misdemeanor only shall
    57
    apply to all crimes, whatever the punishment may be.
    [Emphasis added.]19
    The government argues that the ―or‖ in the statute makes it disjunctive, and
    therefore creates these two categories of aiders and abettors. The government‘s
    position is that Tann and Harris were guilty of the ―first‖ form of aiding and
    abetting, which holds accomplices liable if they advise, incite, or connive ―at the
    offense,‖ regardless of the relationship, if any, between the accomplice and the
    principal. Therefore, the government contends, because Tann and Harris incited
    the crime by shooting at Omar Harrison, causing Foreman also to open fire, Tann
    and Harris need not have ―intentionally associated‖ with Foreman in order to be
    guilty of his crimes (assuming Foreman was the principal).
    19
    The purpose of D.C. Code § 22-1805 was to ―abolish the distinction
    between principals and accessories and render them all principals.‖ 
    Perez, 968 A.2d at 93
    (alterations omitted); see also Standefer v. United States, 
    447 U.S. 10
    ,
    19-20 (1980) (interpreting the similarly-worded federal aiding-and-abetting statute,
    18 U.S.C. § 2 (a) (2014): ―all participants in conduct violating a federal criminal
    statute are ‗principals‘‖); ).(Edward) Thompson v. United States, 
    30 App. D.C. 352
    , 364 (D.C. Cir. 1908) (―By the common law, all persons who command,
    advise, instigate, or incite the commission of an offense, though not personally
    present at its commission, are accessories before the fact, and the object of the
    aforesaid section was to make all such persons principal offenders.‖). The statute
    ―merely extended [the] doctrine of vicarious responsibility to additional classes of
    offenders by treating them as principals.‖ Hazel v. United States, 
    353 A.2d 280
    ,
    283 n.9 (D.C. 1976). That narrow purpose notwithstanding, ―it is not, and cannot
    be, our practice to restrict the unqualified language of a statute to the particular evil
    that Congress was trying to remedy -- even assuming that it is possible to identify
    that evil from something other than the text of the statute itself.‖
    Brogan v. United States, 
    522 U.S. 398
    , 403 (1998).
    58
    The government attempts to bolster this argument by citing to a series of
    cases, particularly from this court, in which the aiding-and-abetting standard is
    articulated with reference to the offense, without dependence on a relationship
    between the accomplice and the principal. See, e.g., English v. United States, 
    25 A.3d 46
    , 52 (D.C. 2011) (―To be guilty as an aider and abettor of a charged offense
    . . . the defendant must be shown to have assisted or participated in that crime with
    guilty knowledge.‖) (internal quotation marks and emphasis omitted); Tyree v.
    United States, 
    942 A.2d 629
    , 637 (D.C. 2008) (―[T]he jury may [] convict of aiding
    and abetting in cases where the evidence is disputed as to who, as between the
    defendant and someone else, was the principal, so long as there is evidence that the
    defendant participated – in one capacity or the other – in the events that led to
    commission of the crime.‖); see also 
    Rosemond, 134 S. Ct. at 1249
    (―So for
    purposes of aiding and abetting law, a person who actively participates in a
    criminal scheme knowing its extent and character intends that scheme‘s
    commission.‖).
    2. Appellants’ Argument
    Appellants‘ argument is that aiding and abetting has historically required the
    aider and abettor to ―intentionally associate‖ himself or herself with a particular
    59
    individual who was the principal, with liability attaching only if the accomplice
    ―know[s] of the principal‘s presence and criminal intentions.‖        Appellants cite
    authorities articulating aiding-and-abetting standards that specifically reference the
    principal in their formulations. See, e.g., 
    Kitt, 904 A.2d at 356
    n.10 (―[T]he basic
    requirement . . . now almost universally accepted [is that] the accomplice be shown
    to have intended that the principal succeed in committing the charged offense.‖)
    (citation and internal quotations omitted) (quoting Wilson-Bey v. United States,
    
    903 A.2d 818
    , 831 (D.C. 2006) (en banc)); United States v. (Dwayne) Washington,
    
    106 F.3d 983
    , 1004 (D.C. Cir. 1997) (elements of aiding and abetting include ―the
    specific intent to facilitate the commission of a crime by another‖); see also
    WAYNE R. LAFAVE, CRIMINAL LAW § 13.2 (b) (5th ed. 2010) (―Generally, it may
    be said that accomplice liability exists when the accomplice intentionally
    encourages or assists, in the sense that his purpose is to encourage or assist another
    in the commission of a crime as to which the accomplice has the requisite mental
    state.‖). Appellants extrapolate that ―intentional association‖ with the principal is,
    and has always been, required for aiding-and-abetting liability.
    Appellants argue that based on the government‘s evidence, the jury could
    have found that Robert Foreman was the principal in the James Taylor murder.
    60
    Because, appellants argue, they had no knowledge of Foreman‘s involvement in
    the incident and no intent to help or encourage Foreman to commit criminal
    activities, they could not have aided and abetted him in his crimes. Although the
    evidence was ambiguous as to who was actually the principal in both the murder
    and the AWIKWA, appellants argue that the court‘s instruction ensured that they
    would be convicted, even if the jury found that Foreman was the principal and that
    appellants had no knowledge of his presence or participation at the time of the
    crime (which would certainly have been reasonable for the jury to do).
    3. Analysis
    Fundamentally, the elements of aiding and abetting are that ―(a) a crime was
    committed by someone; (b) the accused assisted or participated in its commission;
    and (c) his participation was with guilty knowledge.‖ Hawthorne v. United States,
    
    829 A.2d 948
    , 952 (D.C. 2003).20       ―A culpable aider and abett[o]r need not
    20
    See also United States v. (Matthew) Moore, 
    708 F.3d 639
    , 649 (5th Cir.
    2013) (elements of aiding and abetting are: (1) the substantive offense occurred
    (2) the defendant associated with the criminal venture; (3) the defendant purposely
    participated in the criminal venture; and (4) the defendant sought by his actions to
    make the venture successful); United States v. Staten, 
    581 F.2d 878
    , 886-87 (D.C.
    Cir. 1978) (―the elements of the offense of aiding and abetting are: (1) guilty
    knowledge on the part of the accused; (2) that an offense was committed by
    someone; (3) that the defendant assisted or participated in the commission of the
    offense‖) (alterations omitted).
    61
    perform the substantive offense, need not know its details, and need not even be
    present, so long as the offense committed by the principal was in furtherance of the
    common design.‖ United States v. Sampol, 
    636 F.2d 621
    , 676 (D.C. Cir. 1980)
    (citations omitted). ―[I]t is not essential that the principal in the operation be
    identified so long as someone has that status.‖ Gayden v. United States, 
    584 A.2d 578
    , 582 (D.C. 1990) (internal quotation marks and alteration omitted).
    In Wilson-Bey, we dealt with a first-degree premeditated murder prosecution
    under D.C. Code § 22-1805 and held that ―whether the defendant is charged as a
    principal or as an aider or abettor, the government must prove all of the elements
    of the offense, including premeditation, deliberation, and intent to 
    kill.‖ 903 A.2d at 822
    . In doing so, we adopted the rule of United States v. Peoni, 
    100 F.2d 401
    (2d Cir. 1938), and rejected the ―natural and probable consequences‖ approach to
    accomplice liability because it ―impermissibly relieved the government of the
    burden of showing that the accomplice had the mens rea required to be guilty of
    the offense.‖ In re D.N., 
    65 A.3d 88
    , 95 n.8 (D.C. 2013); see also Nye & Nissen v.
    United States, 
    336 U.S. 613
    , 618-19 (1949) (―In order to aid and abet another to
    commit a crime it is necessary that a defendant ‗in some sort associate himself with
    the venture, that he participate in it as in something that he wishes to bring about,
    62
    that he seek by his action to make it succeed.‘‖ (quoting 
    Peoni, 100 F.2d at 402
    )).
    We held that an aider and abettor must act with the mens rea required by the
    specific crime with which the principal is charged and ―be an associate in guilt of
    that crime.‖21 
    Wilson-Bey, 903 A.2d at 831
    (emphasis omitted) (quoting Roy v.
    United States, 
    652 A.2d 1098
    , 1104 (D.C. 1995)). We explained in Wilson-Bey,
    however, that, nothing in the opinion ―casts doubt on the propriety of [an]
    instruction . . . to the effect that a jury may . . . infer that a person intends the
    natural and probable consequences of his or her acts knowingly done or knowingly
    
    omitted.‖ 903 A.2d at 839
    n. 38 (original brackets omitted). Such a presumption,
    we observed, ―does not distinguish between principals and accomplices, nor does it
    expand the liability of one but not of the other.‖ 
    Id. What we
    must do in this case, which we did not do in Wilson-Bey because
    the question was not presented, is determine whether the aider and abettor who
    acts, as Wilson-Bey requires, with the same purpose and intent as the principal
    must also ―intentionally associate‖ with that specific principal. More pointedly,
    21
    Wilson-Bey‘s holding was extended to the offense of AWIKWA, also a
    specific intent crime, and to offenses not requiring specific intent. See McCrae v.
    United States, 
    980 A.2d 1082
    , 1090 (D.C. 2009); see also Perry v. United States,
    
    36 A.3d 799
    , 808 (D.C. 2011) (―We have by now made clear that Wilson-Bey is
    not limited to specific intent crimes.‖) (internal quotation marks omitted).
    63
    the question here is whether the aider and abettor must know of the presence and
    conduct of the specific principal and form the intent to help him or her with the
    commission of his or her crime, as opposed to share simply (with whoever shared
    the aider and abettor‘s purpose) in the mens rea required to commit the crime
    itself.22 Although the evidence was disputed at trial, we assume for the purposes of
    this opinion that it was Robert Foreman who fired the bullets that hit James Taylor
    and Bernard Mackey, and therefore, was the principal in the crimes committed
    against them. We also assume, because here it appears from the record that the
    evidence was undisputed, that Tann and Harris were unaware of Foreman‘s
    presence during the attack.
    22
    Both parties attempt to use the language of Wilson-Bey and Peoni to
    support their argument. Indeed, there is language that cuts both ways in those
    opinions. Compare 
    Wilson-Bey, 903 A.2d at 840
    (―[T]he government must prove,
    in conformity with Peoni, that the accomplice in some sort associated himself with
    the venture, that he participated in it as in something he wished to bring about, and
    that he sought by his action to make it succeed.‖) (emphasis added and internal
    quotation marks and alterations omitted) with 
    id. at 831
    (―Every United States
    Circuit Court of Appeals has adopted Peoni‘s requirement that the accomplice be
    shown to have intended that the principal succeed in committing the charged
    offense . . . .‖) (emphasis added). The same could be said for other opinions of this
    court. Compare 
    English, 25 A.3d at 52
    (―To be guilty as an aider and abettor of a
    charged offense . . . the defendant must be shown to have assisted or participated in
    that crime with guilty knowledge.‖) (internal quotation marks omitted) with 
    id. at 53
    (―The key question is whether . . . [the accomplice] intentionally participated in
    [the principal‘s offense] and that he not only wanted [him] to succeed . . . but that
    he also took concrete action to make his hope a reality.‖). It seems fair to say that,
    in all these cases, the judicial mind was not focused on the issue we now confront.
    64
    The language of D.C. Code § 22-1805 is silent on whether its terms that
    describe the accomplice‘s advising, inciting, conniving, or aiding and abetting the
    principal offender in the criminal venture are to be infused with the ―intentional
    association with a principal of whom the defendant is aware‖ requirement
    advanced by appellants. Our case law is also silent on this specific point.    In the
    normal case, unlike here, there is little question about the alleged accomplice‘s
    awareness of the role of the principal – if not aware of every detail about the
    principal‘s involvement in the crime at issue, the accomplice is at least aware of his
    or her presence and participation.
    Because our statute, like its federal counterpart, incorporates the common
    law,23 we must look to cases with analogous facts interpreting the common law in
    order to test appellant‘s theory that the possibility of recognizing aiding and
    abetting on unusual facts such as those presented in this case was unknown to the
    common law, and that recognizing such liability in this case would create liability
    where it did not exist before. See Outlaw v. United States, 
    632 A.2d 408
    , 411
    (D.C. 1993) (interpreting the elements of D.C. Code § 22-1806, the District of
    23
    See (Edward) 
    Thompson, 30 App. D.C. at 364
    ; see also Rosemond, 134 S.
    Ct. at 1245-46.
    65
    Columbia accessory-after-the-fact statute, in light of the common law in the
    absence of statutory definitions).
    We begin with Whitt v. Commonwealth, 
    298 S.W. 1101
    (Ky. 1927). In that
    case, while appellant Whitt was firing at Scott (a law enforcement officer who was
    attempting to arrest him), a third-party, Stanley, appeared and fatally shot Officer
    Scott. The court observed:
    It is clear that appellant in resisting arrest, and in firing at
    Scott, was attempting to do so to evade arrest, and not
    only is there nothing to show that Stanley was interested
    in appellant’s successful evasion of arrest but there is no
    evidence to show what prompted Stanley in firing the
    shot at Scott. Whether he had any other and different
    reason for firing at him is not disclosed, and there is no
    evidence that appellant advised, counseled, or incited him
    to fire that shot in any way, or that a word had been
    spoken between them in any way just prior to, during, or
    at the time of the difficulty.
    The intent or purpose of appellant in firing at Scott is
    apparent, but there is a lack of evidence from which it
    may be surmised that Stanley in firing his shot shared the
    intent or purpose with which appellant had fired his, or
    in fact what his purpose was.
    
    Id. at 1102
    (italics added). In concluding that Whitt could not be properly be
    convicted as an aider and abettor, the court reasoned:
    66
    In this case we have the intent which prompted appellant
    to commit the offenses committed by him, but there is a
    lack of evidence to show that he shared in any criminal
    intent or purpose which prompted Stanley to fire the fatal
    shot. So far as this record discloses, Stanley may have
    had some criminal intent totally foreign to and
    disconnected from the intent which prompted appellant;
    in other words, Stanley may have seized upon the
    opportunity thus presented to him to even up an old score
    with Scott with which appellant was totally disconnected,
    and with which criminal intent he had no connection and
    no sympathy.
    
    Id. at 1103
    (italics added).24 The court‘s reasoning strongly implies that had there
    been evidence that Stanley ―was interested in appellant‘s successful evasion of
    arrest,‖ that Stanley thus ―shared the intent or purpose‖ with which [Whitt] had
    fired his‖ shot, and that Whitt shared in the purpose which ―prompted Stanley in
    firing the shot at Scott,‖ the court would not have reversed Whitt‘s aiding and
    abetting conviction.
    The reasoning of Landrum v. Commonwealth, 
    96 S.W. 587
    (Ky. 1906), is
    similar to that of Whitt.   There, a group of men, ―more or less drunk‖ and
    24
    Cf. State v. Ochoa, 
    72 P.2d 609
    , 616 (N.M. 1937) (―The accused may not
    be held for the independent act of another even though the same person be the
    victim of an assault by both. In such circumstances there is wanting that sharing of
    criminal intent essential to proof of aiding and abetting.‖).
    67
    motivated by an inter-family quarrel, involved themselves in ―a shooting affray‖
    near the defendant‘s house. 
    Id. at 587-88.
    The defendant, roused from sleep by
    the shooting and also ―more or less drunk‖ while apparently unaware of the
    motivations of the warring families, saw a third-party unassociated with the
    feuding groups ―staggering about‖ and opened fire. 
    Id. at 587.
    The defendant‘s
    bullets struck the third-party but merely wounded him superficially. Meanwhile, a
    bullet fired by someone other than the defendant also hit the third-party, killing
    him. 
    Id. at 587-88.
    There was no evidence that the defendant was acquainted with
    the man who was charged as the principal in the killing. 
    Id. at 588.
    The court, in
    concluding that the defendant could not be guilty of aiding and abetting the actual
    killer, found that ―whatever may have been the purpose or motive of the [other
    shooters] . . . there was not a scintilla of proof that appellant knew of it or shared it
    to any extent.‖ 
    Id. at 588.
    The type of evidence that was missing in Whitt and Landrum is present here.
    Here, according to Little‘s testimony, which the government highlighted in closing
    argument,
    [Foreman] said he seen Ashley [Tyndle] arguing with
    some dude [Harrison] . . . So he said he got out his car
    68
    and start walking towards there and he seen [appellant
    Harris] and somebody else coming around the corner. So
    he said, man, they got it. So he went back towards his
    house . . . . [but then] heard a gunshot . . . [so then he]
    turn[ed] around and start shooting.
    In other words (in conjunction with testimony by other witnesses about Harris‘s
    and Tann‘s actions after hearing about the argument between Harrison and
    Tyndle), Little‘s testimony established (1) that Foreman shot at Harrison for the
    same reason Harris and Tann shot at Harrison, and (2) that Foreman, Harris, and
    Tann shared the purpose that prompted Foreman to fire the fatal shot: to avenge
    Harrison‘s hostile conduct toward the woman (Tyndle) who was the girlfriend of
    22nd Street crew member Little.
    Regarding what constitutes a shared or common ―criminal intent or purpose‖
    in situations where the accomplice may be unaware of the particular presence of
    the principal, we have identified three cases of note. In State v. Ochoa, 
    72 P.2d 609
    , two defendants were part of a crowd of over 100 people that attacked the
    county sheriff in an attempt to free a prisoner in the sheriff‘s custody. Shots were
    exchanged between the mob and the police. 
    Id. at 617.
    None of the shots were
    fired by the defendants, but one of the shots killed the sheriff. The defendants
    69
    assaulted several of the sheriff‘s deputies, preventing them from coming to the
    sheriff‘s aid. The Ochoa court held that ―[t]he fact that [the defendants] were thus
    engaged in a vicious assault upon [the deputy], . . . left it within the jury‘s province
    to infer, if it saw fit, not alone that these defendants shared in the intent of the
    slayer, but also that they aided and abetted him in his unlawful undertaking.‖ 
    Id. (citing Woolweaver
    v. State, 
    34 N.E. 352
    , 353 (Ohio 1893)). Pertinent here, the
    court so held even though it appears there was no evidence that the defendants (or
    anyone else) knew with particularity of the presence and participation of the
    sheriff‘s actual killer or took particular notice of everyone who populated the mob.
    In State v. Kukis, 
    237 P. 476
    (Utah 1925), an armed mob of 65 to 100
    striking laborers, including the defendant, fired on a railroad car containing
    management representatives. One of the bullets, fired by an unknown member of
    the mob, struck a railcar worker and killed him. The court held that there was:
    [A] just inference that every one of the crowd . . . was
    there for a common and unlawful purpose, and
    participated or aided and abetted in the assault. . . . There
    thus is evidence to justify a finding of combination or
    confederacy or concert of action of this armed crowd or
    mob . . . that all who were members or part of such
    crowd or mob . . . aided or abetted therein; and though
    the evidence does not show whether it was or was not the
    bullet shot by the defendant or by another member of the
    70
    mob which killed the deceased . . . the jury was justified
    in finding him guilty. . . .
    
    Id. at 479.
    In People v. Cooks, 
    625 N.E.2d 365
    (Ill. Ct. App. 1993), the murder victim
    and defendant belonged to enemy gangs.           Following an argument between
    members of the two gangs, the defendant followed the victim as he entered a
    tavern vestibule. The defendant ―ran up to the front of the tavern and fired [his]
    gun through the [tavern] window, striking [the victim] in the leg.‖ 
    Id. at 367.
    ―The arm of an unidentified individual then stuck a shotgun through the tavern
    door, and fired it once, striking [the victim] in the stomach and killing him.‖ 
    Id. at 367-68.
    The person to whom ―the arm‖ belonged was never identified. 
    Id. at 368.
    Cooks argued on appeal that ―the State failed to prove that he solicited,
    aided, abetted or agreed or attempted to aid the unknown, unidentified person who
    shot and killed [the victim].‖ 
    Id. The Illinois
    court stated that the ―intent to
    promote or facilitate the commission of a crime can be shown by evidence that the
    defendant shared the criminal intent of the principal or that there was a common
    design or community of unlawful purpose.‖ 
    Id. at 368.
    The court concluded that
    ―the evidence . . . sufficiently demonstrate[d] a common design and a community
    of unlawful purpose between the defendant and the second unidentified
    71
    individual,‖ 
    id. at 370,
    and that it was logical to conclude that the defendant aided
    the second unidentified shooter ―by virtue of his shooting the victim first, thereby
    making [the victim] more vulnerable and prone to a second attack.‖ 
    Id. at 369.
    The court held that the ―[d]efendant‘s first shot facilitated the second [shot by the
    ―arm‖] and, therefore, the offense.‖ 
    Id. The reasoning
    in Ochoa, Kukis and Cooks is relevant here, because there
    was evidence from which the jury could infer that Harris and Tann were aware that
    other gang members, too, were shooting at Harrison, prompted by the altercation
    between Harrison and Tyndle. Under the rationale of these cases, even if Tann and
    Harris were not aware of the presence and participation of each one of the 22nd
    Street crew-member shooters and did not know who fired the fatal shot, they could
    be held liable as aiders and abettors of whichever other crew-member shooter —
    including Foreman — was the principal (whose action was facilitated and
    encouraged by Harris‘s and Tann‘s own actions).
    Haynes v. Commonwealth, 
    515 S.W.2d 240
    (Ky. 1974), a case discussed by
    our dissenting colleague, is also helpful to our analysis. The question addressed in
    that case was, ―under what circumstances does a person engaged in an affray
    72
    become an aider and abettor of another who intervenes uninvited, even assuming
    that they share the criminal intent or purpose‘‖ (quoting Whitt). The facts were
    that ―appellants John Robert and Tounsel Haynes[] were engaged in . . . a ‗shoot-
    out‘ with William Caudill‖ when their father, ―appellant Joe Haynes[,] armed
    himself with a rifle, went to the scene of the affray, and shot and killed 
    Caudill.‖ 515 S.W.2d at 240-241
    . All three Hayneses were indicted for murder and found
    guilty of voluntary manslaughter. 
    Id. at 241.
    The Court of Appeals of Kentucky
    held that the evidence did not justify the sons‘ conviction of the father‘s act,
    reasoning that there was ―no evidence from which it may be reasonably inferred . .
    . that either of the sons sent for the father‖ and ―no evidence even that John Robert
    knew he had arrived until after the killing.‖ 
    Id. Further, the
    court reasoned, ―the
    fact that Tounsel may have provoked the encounter‖ ―would not itself amount to
    assistance or encouragement.‖ 
    Id. Here, by
    contrast, the evidence was not merely
    that Harris and Tann provoked Foreman‘s encounter with Taylor and Mackey.
    Rather, there was evidence from which it could be inferred (1) that Harris‘s and
    Tann‘s action in shooting at Harrison was an invitation to (i.e., a ―sending for‖)
    22nd Street crew members (who, as discussed above, were participants in an
    overall conspiracy ―to assault and kill anyone whose interests were contrary to
    those of [appellants] and their associates‖) to come and support Harris‘s and
    73
    Tann‘s efforts; and (2) that Harris and Tann knew before the fatal shot was fired
    that other 22nd Street crew members were in fact joining the affray (even though
    there was no evidence that they knew that Foreman in particular was one of the
    participants).
    In other words, contrary to our dissenting colleague‘s argument, the
    Kentucky court‘s decision in Haynes does not undercut our argument that Tann
    and Harris could be found guilty of aiding and abetting Foreman‘s shooting of
    James Taylor. Given that all three individuals shared the same mens rea to shoot
    Harrison and the evidence demonstrated that Tann and Harris reasonably knew that
    their actions would incite other 22nd Street crew members to come to their aid, we
    think the situation here is more analogous to those in Ochoa and Kukis, where
    courts concluded that an individual participating in a criminal mob could be found
    guilty of aiding and abetting the commission of a murder by a member of the mob,
    even if the aider did not know who exactly from the mob did the actual killing. In
    fact, even our dissenting colleague agrees that, in instances of a criminal mob, a
    person who ―knowingly attaches himself to a large group‖ may be considered to
    have aided and abetted other members of the group to commit illegal acts even
    74
    though ―he may not know who is in the group or who the principal offenders in it
    are.‖
    We believe that the case law supports the following propositions rooted in
    the common law and incorporated in our aiding-and-abetting statute: (1) the aider
    and abettor must have the mens rea of the principal actor, see 
    Wilson-Bey, 903 A.2d at 822

    . These
    principles satisfy the criminal intent element required by aiding-and-abetting
    liability and do not run afoul of Wilson-Bey or Peoni.27
    Applying these principles to the facts of this case, we think it is clear that
    appellant Tann, appellant Harris, and Robert Foreman all possessed the same
    criminal state of mind: the premeditated intent to kill Omar Harrison. This intent
    shifted to the killing of James Taylor, and the assault of Bernard Mackey, under
    26
    ―A man is held to intend the foreseeable consequences of his conduct.‖

    27
    Because our holding rests in part on foreseeability (and the inference of
    intentionality that may be drawn from it), it is not accurate to say, as our dissenting
    colleague complains, that our holding is that one can be an aider/abettor by being
    an ―inadvertent accomplice.‖ One cannot ―inadvertently‖ aid or abet a principal
    when he or she shares the mens rea of the principal and it is reasonably certain that
    his or her actions will incite the principal to action because of their shared
    membership in a group (e.g., a gang or mob) that has a communal purpose. Our
    dissenting colleague also states that our ―community of purpose‖ formulation ―may
    exist in the absence of any agreement, understanding, or cooperation between [the
    principal and ‗putative‘ accomplice] with respect to the crime in question.‖ We
    emphasize that a ―community of purpose‖ necessarily implies that there exists
    some tacit, if not always explicit, agreement or understanding between all involved
    (such as a code of conduct), even if there is no agreement to commit a specific
    crime. See infra n.28.
    76
    the theory of transferred intent as recognized in our case law and not in dispute
    here.    (Wesley) Williams v. United States, 
    881 A.2d 557
    , 567 (D.C. 2005);
    O’Connor v. United States, 
    399 A.2d 21
    , 25 (D.C. 1979).
    The evidence also established a ―community of purpose‖ between Tann,
    Harris, and Robert Foreman, reflecting a uniform and common design among the
    three shooters.   When word of the confrontation between Alphonce Little‘s
    girlfriend and Omar Harrison spread through 22nd Street, Tann, Harris, and Little
    rushed with other gang members toward Harrison in anticipation of a
    confrontation. The evidence supported a finding that appellants were well aware
    that other gang members were in the area and part of the crowd that was involved
    in the general attack. Both appellants knew from past experience while in the 22nd
    Street Crew that once they began committing acts of violence, other coconspirators
    would join them. In fact, the conspiracy among members of the 22nd Street Crew
    included the agreement to commit violence against outsiders, like Harrison, who
    failed to afford the proper respect to the gang and its territory, and whose
    ―interests‖ were contrary to that of the gang. Not surprisingly, this is exactly what
    happened when Foreman (who we assume was the principal in this incident)
    77
    opened fire in response to seeing his fellow coconspirators engaged in an attack on
    Harrison as their response to Harrison‘s hostility toward Tyndle. 28
    We cannot agree with Judge Glickman that, by looking to the foreseeability
    to the defendant that his criminal conduct will incite participation by a third party
    acting pursuant to a community of purpose, we have expanded the doctrine of
    aiding and abetting liability ―without affording the parties the opportunity to
    address‖ the ―expan[sion],‖ and that we have thereby been ―unfair to the parties.‖
    Both the factor that we refer to as ―community of purpose‖ and foreseeability are
    factors whose relevance the parties debated in the trial court from the outset. For
    example, Harris‘s counsel argued that the aider and abettor must have ―a
    connection with the principal‖ and that there must be ―an association between the
    28
    We need not find an actual agreement here to commit the specific crime
    between the various gang members in the way that we would if the finding of guilt
    were predicated on Pinkerton conspiracy liability. ―Aiding, abetting, and
    counseling are not terms which presuppose the existence of an agreement. Those
    terms have a broader application, making the defendant a principal when he
    consciously shares in a criminal act, regardless of the existence of a conspiracy.‖
    Pereira v. United States, 
    347 U.S. 1
    , 11 (1954) (citing Nye & Nissen, 336 U.S at
    620). Nevertheless, the fact that there was a broader conspiracy to kill ―outsiders‖
    among the 22nd Street Crew members informs the community of purpose that, as a
    factual matter, was shared between Tann, Harris, and Foreman at the time of the
    shooting. The existence of the conspiracy was what made it foreseeable to Harris
    and Tann that other 22nd Street crew members in the area — including,
    unbeknownst to them, Foreman — would respond by joining in the effort to shoot
    Omar Harrison.
    78
    people helping each other.‖ Counsel also discussed with the trial court whether the
    principal and the aider/abettor could have ―totally different motives for killing Mr.
    Harrison.‖ And, in Harris‘s brief on appeal, he decries the absence of a ―relational
    limiting factor‖ for aiding and abetting liability.
    The parties also argued in the trial court about the relevance of the
    foreseeability of the principal‘s actions. For example, in the course of a colloquy
    with the trial court about accomplice liability instructions, Harris‘s counsel, joined
    by Tann‘s counsel, argued that for such liability, ―it would have to be reasonable
    and foreseeable that, ―if you‘re doing something,‖ ―an unknown person . . . would
    respond by shooting.‖      Further, while Harris‘s counsel argued that the evidence
    did not support an aiding and abetting instruction because ―[t]here‘s no way Mr.
    Harris could have known that somebody across the street who[m] he didn‘t know
    was there . . . would have suddenly joined in on this shooting,‖ he explicitly
    understood that the government ―keeps trying to say well, yeah, because he‘s on
    22nd Street.‖ In other words, counsel understood that one argument being
    advanced by the government was that because the shooting took place on 22nd-
    Street-crew turf — where the ethos was for crew members to work together ―to
    assault and kill anyone whose interests were contrary to those of [crew members]
    79
    and their associates‖ — Harris and Tann had every reason to expect that when they
    started shooting, other crew members who happened to be in the area would start
    shooting as well.    Defense counsel argued that Foreman made ―a completely
    independent decision to start shooting‖ and that there was no way Harris and Tann
    ―could anticipate that someone he didn‘t know was even present would do
    anything, much less start shooting.   They made this argument while anticipating
    that ―the government may argue that [the defendants] should have know[n] that
    [their] act of shooting at a person who had been assaulting a pregnant woman
    [Tyndle] would have incited others to shoot as well. And, in fact, the government
    did argue, in opposing Harris‘s motion for judgment of acquittal (1) that because
    Harris, Tann, and Foreman were ―all members of the charged conspiracy,‖ there
    was ―no legitimate argument to make that [they] were acting independently of one
    another‖;29 (2) that because there was an ―over-arching conspiracy,‖30 crew
    29
    Contrary to Judge Glickman‘s suggestion, the evidence did not support a
    finding that Foreman‘s decision to join in the shooting was an ―independent
    criminal act of another that the defendant[s] did not intentionally encourage or
    assist in some way.‖ According to the evidence, Foreman, Harris, Tann, and the
    other 22nd Street crew members who joined in the shooting did not act
    ―independently‖ of each other.
    30
    As Judge Glickman notes, the government did not rely on the doctrine of
    Pinkerton liability in prosecuting Harris and Tann for the Taylor and Mackey
    incident, but, as the material quoted in the text shows, it did rely on the existence
    of the charged conspiracy to establish why it was foreseeable to Harris and Tann
    (continued…)
    80
    members ―immediately knew what to do31 and reacted in a way to protect the
    girlfriend of their co-conspirator‖; (3) that Foreman ―did exactly what [defendants]
    had every reason to believe [he] would do‖; and (4) that, in light of Foreman‘s
    membership in a conspiracy that ―will protect . . . their members at all costs,‖ ―[i]t
    was certainly foreseeable that when Harris [and Tann] began shooting . . ., other
    co-conspirators, [they] may not have known exactly who, would assist in [their]
    efforts.‖ Thus, is fair to say that one express theory of the prosecution was that
    (…continued)
    that Foreman and other 22nd Street crew members would respond as they did, by
    joining in the shooting. This did not amount (and our analysis does not amount) to
    conflating Pinkerton liability and aiding-and-abetting liability (which requires a
    mens rea that Pinkerton does not). See 
    Wilson-Bey, 903 A.2d at 840
    -41. Rather
    than conflation of theories of liability, our analysis reflects a recognition that
    ―[t]ypically, the same evidence will support both a conspiracy and an aiding and
    abetting conviction.‖ United States v. Vasquez, 
    677 F.3d 685
    , 695 (5th Cir. 2012)
    (internal quotation marks omitted).
    31
    In closing argument, the prosecutor continued that theme:
    Now, what does Robert Foreman tell you? . . . I hear
    shots. So what do I do? These are my boys. I turn
    around, and I start shooting.‖ . . . I hear the shots. I
    don’t even have to think. I turn around; I start shooting.
    81
    Harris and Tann foreseeably (and thus intentionally, the jury could find)
    encouraged an attack on Omar Harrison by a group that included Foreman.32
    Moreover, in a memorandum regarding proposed jury instructions, Harris‘s
    counsel told the court that the defense had looked for but had been ―unable to find
    a fact pattern matching the one in this case,‖ but found cases ―across jurisdictions‖
    (purportedly) requiring, for joint liability, ―that the defendant had knowledge of the
    other principal involved in the event.‖        Having undertaken such a search,
    appellants cannot be surprised that this court, too, has scoured common-law cases
    on accomplice liability and has relied on factors that these cases recognized as
    relevant. The case law discussed herein was equally available to the parties as part
    of their research.
    All the foregoing examples show that the parties had ample opportunity to
    debate, and did debate, the relevance of the factors on which we rely for our
    holding.
    32
    Again, we rely on the principle that Harris and Tann could be found to
    have intended the reasonably foreseeable consequences of their acts. See supra
    note 26.
    82
    Judge Glickman‘s analysis suggests that after Peoni and Wilson-Bey, Harris
    and Tann may not be found liable for the foreseeable shooting their actions
    inspired.   But what Peoni established is that ―the probability that the forbidden
    result would follow upon the accessory‘s conduct‖ does not suffice; rather, to incur
    aiding and abetting liability, the defendant must ―in some sort associate himself
    with the venture, . . . participate in it as in something that he wishes to bring about,
    . . . seek by his action to make it succeed[,]‖ and have a ―purposive attitude
    towards 
    it.‖ 100 F.2d at 402
    .33 The evidence at trial amply supported a finding
    that Harris and Tann each associated himself with the vendetta against Harrison,
    participated in it as in something that he wished to bring about, sought by his
    action to make it succeed, and displayed a purposive attitude towards it, as Peoni
    requires for aiding and abetting liability. What Wilson-Bey and its progeny require
    is that the aider and abettor share the mens rea of the principal; it is not enough for
    33
    Judge Glickman also observes that, of the five cases that we cite to, four
    were decided before Peoni, and one was decided under a statute that has no
    counterpart in this jurisdiction. With regard to the four pre-Peoni cases, it does not
    matter that the Kentucky, New Mexico, and Utah cases were decided beforehand
    because those cases do not conflict with Peoni‘s principal holding. In none of the
    four cited cases is there any dispute that the aider/abettor shared the same mens rea
    as that of the unknown or inadvertent principle. With regard to the Illinois case
    Cooks, the ―common design or community of unlawful purpose‖ doctrine of
    proving an intention ―to promote or facilitate a crime‖ is rooted in the common
    law, and not found in the statute. See 
    Cooks, 625 N.E.2d at 368-69
    ; see also
    People v. Foster, 
    556 N.E.2d 1214
    , 1219 (Ill. Ct. App. 1990).
    83
    aiding and abetting liability that a defendant could reasonably have foreseen what
    the principal would do. Here, there is no dispute that the evidence sufficed to show
    that Harris and Tann shared Foreman‘s intent to kill Harrison. The question is
    whether, sharing that intent, they may be held liable under an aiding and abetting
    theory for initiating a shooting incident that they had reason to foresee would cause
    (and did cause) other gang members to join in the shooting. Neither Peoni nor
    Wilson-Bey requires us to answer that question in the negative.34
    We would reach a different conclusion had there been no evidence
    establishing community of purpose between Tann, Harris, and Robert Foreman,
    and if the evidence had not supported an inference that Harris and Tann knew that
    fellow 22nd Street crew members were joining in the assault and that it was
    34
    Judge Glickman notes that this court ―declared in Wilson-Bey that it is a
    ‗requirement [for aiding and abetting liability] that the accomplice be shown to
    have intended that the principal succeed in committing the charged offense‘‖ and
    further stated in Little v. United States, 
    989 A.2d 1096
    , 1102 (D.C. 2010), that the
    ―aider or abettor must have knowingly aided the other person with the intent that
    the other person commit the charged crime.‖ It is consistent with Wilson-Bey and
    Little for us to hold more specifically here that the aider/abettor must ―have
    intended that the principal (whoever, among his associates who could reasonably
    be expected to participate pursuant to a common purpose if present on the scene,
    that principal might turn out to be) succeed in committing the charged offense‖
    and ―must have knowingly aided the other person (whoever, among his associates
    who could reasonably be expected to participate pursuant to a common purpose if
    present on the scene, that person might turn out to be), with the intent that the
    other person commit the charged crime.‖
    84
    foreseeable to Harris and Tann that any fellow crew members who were in the area
    would do so. If the facts were such as those in Landrum, where there was no
    evidence of a community of purpose between the defendant aider and abettor and
    the principal, then the evidence would be insufficient. But the evidence was that
    Foreman, a gang member who lived around 22nd Street and was acquainted with
    Harris and shared guns with him, was about to step in to respond to the Harrison-
    Tyndle altercation until he perceived that Harris and others ―got it,‖ and then
    joined in the shooting when ―getting it‖ — the common purpose and design —
    escalated to that level. And, as in Cooks, Tann‘s and Harris‘s actions of initiating
    the shooting, and rendering the target more vulnerable, facilitated and encouraged
    Foreman‘s joining in the gunfire to help his 22nd Street Crew 
    cohorts. 625 N.E.2d at 369-70
    . The fact that Tann and Harris were unaware of Foreman‘s presence
    until after Foreman (presumably) fired the fatal shot does not make the
    government‘s evidence legally insufficient.
    The dissent derides our reasoning as a ―novel theory of [our] own devising.‖
    We think the cases discussed above, decided decades (and, in one instance, a
    century) ago, show that our theory is not at all novel. Rather than of our own
    devising, it is authorized as an incremental development of the common law, from
    85
    reasoning that is implicit in the decades-old cases we have cited.35 The fact that
    there seems to be no reported case that has articulated the theory precisely as we
    have is hardly surprising because, as the trial court and the parties all agreed, the
    facts of this case are ―very odd‖ and ―rare.‖ And, however imprecise the rule we
    announce may be, it is anchored to, and limited in application by, the detailed and
    unusual facts of this case.
    Accordingly, for the foregoing reasons, we deny appellants‘ claims related
    to the sufficiency of the evidence. We also deny appellants‘ claims related to the
    curtailment of their closing arguments when the trial judge prevented them from
    arguing that aiding-and-abetting liability required the government to prove that the
    accomplice intended to help a known and particular principal commit the charged
    offense. In this respect, the trial judge acted correctly because he prevented a
    35
    As the highest court of this jurisdiction, we of course have the ―power[]
    [and the responsibility] to develop the common law for the District of Columbia,‖
    Williams v. Walker-Thomas Furniture Co., 
    350 F.2d 445
    , 449 (D.C. Cir. 1965), ―as
    new circumstances and fact patterns present themselves.‖ Rogers v. Tennessee,
    
    532 U.S. 451
    , 461 (2001). As far as we can tell, no other reported opinion has
    considered whether there can aiding and abetting liability on facts such as those
    presented here: a principal whose particular presence was not known to the
    defendants, but who, because of his membership in an over-arching conspiracy
    with the defendants, was foreseeably incited to join in the defendants‘ criminal
    conduct. We must answer the question on our own, and we do so in a way that we
    believe is consistent with the pronouncements in aiding-and-abetting case law, in
    all their variations.
    86
    misstatement of the law. See United States v. Gaines, 
    690 F.2d 849
    , 858 (11th Cir.
    1982) (no error where the trial ―court properly prevented defense counsel from
    arguing to the jury a false legal proposition‖); see also Hager v. United States, 
    791 A.2d 911
    , 913 (D.C. 2002) (trial court acts properly where it ―exclude[s] . . . those
    statements that misrepresent the evidence or the law‖).
    However, we conclude that the trial judge committed instructional error
    when he told the jury that a defendant can be found liable as an aider and abettor
    ―if [he] knowingly aid[s] and abet[s] the crime without knowing who else is doing
    it,‖ without requiring that the jury also find a community of purpose between the
    principal and the accomplice. Nevertheless, using any test for error, we conclude
    that appellants were not harmed. The jury convicted both Tann and Harris of
    Count 1 of the indictment, which alleged that appellants were involved in a
    criminal conspiracy with other members of the 22nd Street Crew to kill persons,
    such as Omar Harrison, whose ―interests‖ were contrary to that of the
    coconspirators. Count 1 included Foreman as a named coconspirator. Given the
    jury‘s finding on the conspiracy count, and given the other evidence presented
    regarding the behavior of Robert Foreman, Harris, Tann, and other gang members
    at the time of the shooting of James Taylor and Bernard Mackey, we find that there
    87
    is no reasonable possibility, even had the jury found that Foreman was the
    principal in the James Taylor-Bernard Mackey incident, that it would have failed to
    find that Tann, Harris, and Foreman were part of a group that shared the common
    purpose and design to murder Omar Harrison and that Harris and Tann intended to
    aid any of their fellow crew members who were present and participating in doing
    so.36 See Fortson v. United States, 
    979 A.2d 643
    , 661 (D.C. 2009); 
    Tyree, 942 A.2d at 638-40
    ; cf. 
    Wilson-Bey, 903 A.2d at 844-45
    . Therefore, appellants are
    entitled to no relief.
    D. Beaver’s Conviction: Obstruction of Justice
    Count 25 of the superseding indictment in this case read as follows:
    Between on or about April 30, 2004, and on or about July
    11, 2006, within the District of Columbia, Lannell N.
    Cooper . . . Michael D. Tann . . . Dajuan D. Beaver . . .
    and Brian K. Gilliam . . . corruptly persuaded, and
    endeavored to cause or induce, Laquanda Johnson, with
    the intent to persuade her to influence, delay, and prevent
    the truthful testimony of her sister, Kyara Johnson, a
    witness in an official proceeding, to wit, United States v.
    Lannell Cooper . . . then pending in the Superior Court
    for the District of Columbia.
    36
    We respectfully disagree with our dissenting colleague‘s suggestion that
    appellants Harris and Tann ―did not intend to aid or abet anyone (other than
    themselves)[.]‖
    88
    On appeal, appellant Beaver makes the argument that although there was testimony
    at trial that he was involved in the search for both Johnson sisters in the run-up to
    appellant Cooper‘s 2006 trial in an effort unlawfully to influence their testimony
    separately, there was insufficient evidence admitted to prove that he committed the
    particular actions alleged by Count 25, i.e., that he attempted to use Laquanda as
    an instrument to influence Kyara‘s testimony against Cooper.             In substance,
    Beaver alleges that what was charged was at variance with the evidence elicited at
    trial.
    Alphonce Little testified that, shortly after Cooper was confined on April 30,
    2004, for the Terrence Jones murder, Beaver told Little that Kyara Johnson was
    cooperating with the government.        Moreover, Little stated that Beaver also told
    him 17th Street gang members Brian Gilliam and Tyrell Hargraves, close friends
    of Cooper and allies of the 22nd Street Crew, would be ―handling the situation‖
    with regard to Kyara.      Little also testified that he saw Beaver meet with Gilliam
    and Hargraves multiple times on 22nd Street after Cooper was arrested. Around
    this time, Beaver also expressed to Little his opinion that the witnesses who were
    snitching on Cooper ―[s]hould be dead.‖ While in jail, Cooper told Little over the
    phone that a friend of his was coming to 22nd Street and Little should identify
    89
    Kyara for him. On the same day as Alphonce Little‘s conversation with Cooper,
    Gilliam came to the neighborhood and met Little in a parking lot. Gilliam was
    seated in a car with a gun in his lap and asked Little ―Where that bitch at[?]‖ and to
    ―point [Kyara Johnson] out.‖
    Furthermore, gang ally Dewey Chappell testified that Beaver told him that
    both of the Johnson sisters were ―supposed to be testifying for the government.‖
    Chappell then traveled to 22nd Street ten to twenty times in an attempt to find the
    sisters with the intent to offer them marijuana and money ―to not testify‖ or to
    ―change their statement.‖ Because Chappell did not know what the sisters looked
    like, Beaver tried to help him find them.
    There was also testimony at trial about the nature of the relationship between
    the sisters. Laquanda Johnson, as the older sister, was known to be ―a sort of
    middleman‖ or ―gatekeeper‖ between Kyara and persons seeking access to her, at
    least for members of the 22nd Street Crew who were looking for Kyara in the
    aftermath of the Terrence Jones murder. An investigator assigned to Cooper‘s
    defense team for his 2006 trial for the murder of Terrence Jones testified during the
    instant case that his ―best chance to speak to [Kyara] was through [Laquanda].‖
    90
    Although Beaver styles his claim as one attacking the sufficiency of the
    evidence, it is better cast as an argument alleging a fatal variance between the
    proof and the pleadings. See (Royce) Robinson v. United States, 
    697 A.2d 787
    ,
    788-89 (D.C. 1997).      Beaver does not dispute that the government presented
    sufficient evidence that Beaver was looking for both sisters in order to prevent the
    truthful testimony of at least one of them. Beaver‘s complaint is that the criminal
    offense did not happen in the way alleged in the indictment – that he did not
    attempt to persuade Laquanda to influence Kyara‘s testimony.
    Two kinds of problems arise when there is a deviation
    from an indictment. An amendment of the indictment
    occurs when the charging terms of the indictment are
    altered . . . . A variance occurs when the charging terms
    of the indictment are left unaltered, but the evidence
    offered at trial proves facts materially different from
    those alleged in the indictment.

    , 1005 (D.C. 1991) (emphasis
    omitted). A ―constructive amendment of the indictment can occur if, and only if,
    the prosecution relies at the trial on a complex of facts distinctly different from that
    which the grand jury set forth in the indictment.‖ Baker v. United States, 
    867 A.2d 988
    , 999 (D.C. 2005) (emphasis omitted) (quoting Carter v. United States, 
    826 A.2d 300
    , 306 (D.C. 2003)). In a variance, the proof at trial does not show such a
    distinctly different ―complex of facts,‖ nor does the proof differ from the ―essential
    91
    elements‖ of the offense charged in the indictment. Marshall v. United States, 
    15 A.3d 699
    , 710 (D.C. 2011). ―In contrast with an amendment, a variance will not
    warrant dismissal except upon a showing of prejudice.‖ (Terrence) 
    Ingram, 592 A.2d at 1006
    (internal quotation marks omitted). ―A variance is prejudicial if it
    either deprives the defendant of an adequate opportunity to prepare a defense . . .
    or exposes him to the risk of another prosecution.‖ Zacarias v. United States, 
    884 A.2d 83
    , 87 (D.C. 2005).
    Here, because the purported discrepancy between the proof elicited at trial
    and the language of Count 25 did not show a ―complex of facts distinctly different
    from that which the grand jury set forth in the indictment,‖ the issue is one of a
    potential prejudicial variance. A constructive amendment is not found where the
    proof at trial reflects the same facts as those alleged in the indictment regarding
    time, place, individuals, and core criminal behavior. See 
    Carter, 826 A.2d at 306
    -
    07.
    Both the evidence at trial and the indictment reflected events that occurred at
    the same time (between the date of Cooper‘s arrest for the Terrence Jones murder
    and Cooper‘s 2006 conviction), in the same general location, by the same
    92
    individuals (22nd Street Crew members, including Beaver, and other gang allies),
    and targeting the same ultimate victim, Kyara Johnson.               See 
    id. at 306.
    Additionally, both the indictment and the evidence at trial showed the same overall
    substantive criminal behavior: an attempt by Beaver and others to commit the
    offense alleged by the grand jury – to intimidate Kyara Johnson for purposes of
    affecting her testimony and the outcome of Cooper‘s 2006 trial. See 
    Baker, 867 A.2d at 999
    . The possible disparity between the indictment and the evidence was
    in manner of the offense only.
    Moreover, as Beaver did not raise the issue of either constructive
    amendment or prejudicial variance at trial, we must review his claim under the
    plain error standard.37 ―Under the plain error doctrine, appellant must establish (1)
    that the trial court committed error; (2) that the error was plain, i.e., clear or
    obvious; (3) that the error affected substantial rights; and (4) that a failure to
    correct the error would seriously affect the fairness, integrity, or public reputation
    37
    Even if we were to find a constructive amendment here, our review would
    still be for plain error. O’Brien v. United States, 
    962 A.2d 282
    , 321 (D.C. 2008)
    (―Since appellant did not raise her claim of constructive amendment in the trial
    court, our review . . . is for plain error.‖); cf. Peay v. United States, 
    924 A.2d 1023
    ,
    1027 (D.C. 2007) (―If there has been a constructive amendment to an indictment,
    and the issue has been properly preserved for appeal, per se reversal is required.‖).
    93
    of judicial proceedings.‖ 
    Marshall, 15 A.3d at 710
    (internal quotation marks and
    emphasis omitted) (citing United States v. Olano, 
    507 U.S. 725
    , 732-36 (1993)).
    We find no plain error. First, we are not convinced that the trial court
    committed ―clear‖ or ―obvious‖ error by failing to identify, sua sponte, that the
    variance between the government‘s proof and the indictment was material. The
    evidence was that Beaver repeatedly attempted, on behalf of Cooper, to identify
    Kyara and Laquanda Johnson for gang members and allies who were looking to
    obstruct justice. Considering this evidence in the context of Laquanda‘s reputation
    in the community as the ―gatekeeper‖ for persons seeking to access Kyara, the
    court (and the jury) could have reasonably inferred: that Kyara was Beaver‘s
    primary focus, that his interest in finding Laquanda was fueled by his concern that
    Kyara would give testimony unfavorable to Cooper, and that Beaver wanted to use
    Laquanda to influence Kyara‘s testimony. See 
    Marshall, 15 A.3d at 711
    (variance
    not plain error where the factual theory pursued by the government at trial ―was
    not entirely divergent from that proffered by the government before trial‖).
    Moreover, even assuming that any error was clear or obvious, Beaver has
    not identified how the variance resulted in surprise, lack of notice, risk of double
    94
    jeopardy, or some other way in which his substantial rights were impacted. 
    Carter, 826 A.2d at 307
    (―A variance may be prejudicial if . . . the accused . . . was so
    surprised by the proof that he was unable to prepare his defense adequately.‖)
    (internal quotation marks omitted); Pace v. United States, 
    705 A.2d 673
    , 677 (D.C.
    1998) (―A variance may prejudice a defendant such as by (1) depriving him of
    adequate pretrial notice of the details of the charge against which he must defend,
    and/or (2) depriving him of protection against reprosecution.‖).         Nor does he
    contend that his defense, which was that the testimony of Alphonce Little and
    Dewey Chappell was untrue, would have been different if there had been no
    variance. 
    Zacarias, 884 A.2d at 89
    . Finally, we are confident that there was no
    error that seriously affected the fairness, integrity, or public reputation of judicial
    proceedings, especially given that Beaver now concedes that the evidence was
    sufficient that he did, in fact, obstruct justice with regard to both of the Johnson
    sisters. See 
    Marshall, 15 A.3d at 711
    .
    E. Beaver’s Conviction:              Carrying a Pistol Without a License
    (“CPWL”)
    Count 47 of the superseding indictment charged that on or about July 11,
    2006, the day of Laquanda Johnson‘s murder, Beaver carried a pistol without a
    license. Alphonce Little testified that shortly before he killed Laquanda, he saw
    95
    Beaver with ―a nine‖ (the parties agree that this referred to a 9mm semi-automatic
    pistol) in his possession.     Little further testified that he and Beaver initially
    planned that Beaver would shoot Laquanda and Kyara Johnson, and that Beaver
    declared that ―he was going to do it[;] he was going to kill them‖ because ―they
    [the Johnson sisters] got to go.‖
    However, Beaver eventually persuaded Alphonce Little to carry out the
    shootings instead. Little obtained a different weapon, a ―.45,‖38 which he used to
    kill Laquanda Johnson and shoot Keisha Frost. Following the shooting, Little,
    Beaver, and Rushing, traveled to Maryland where Beaver took the murder weapon,
    and the hoodie that Little had been wearing, and hid these items near the porch of
    his mother‘s house.39 The 9mm pistol that Beaver was carrying earlier in the
    evening was never recovered by investigators.
    38
    Although not clearly articulated in testimony, the only reasonable
    inference was that the term ―.45‖ referred to a .45 handgun.
    39
    The government does not argue that the CPWL conviction can be
    supported based on Beaver‘s possession of the .45 handgun because there was no
    evidence that Beaver possessed the weapon in the District of Columbia. See
    Joiner-Die v. United States, 
    899 A.2d 762
    , 765-66 (D.C. 2006) (Superior Court
    jurisdiction limited to acts which occur within the boundaries of the District of
    Columbia).
    96
    Beaver argues that his CPWL conviction was based on insufficient evidence
    because there was no evidence, direct or circumstantial, that his 9mm pistol was
    operable as required by the law at the time of trial.40 In re R.S., 
    6 A.3d 854
    , 859
    (D.C. 2010). Beaver specifically contends that there was no demonstration by the
    government of his ―active reliance‖ on the weapon which might constitute
    circumstantial evidence of operability.
    In cases such as this one, where there is no evidence that the defendant fired
    the firearm, its operability may be established by circumstantial evidence,
    including evidence that ―affirmatively demonstrated [the defendant‘s] belief that it
    was operable.‖ 
    Id. at 860.
    This court held in In re R.S. that evidence that the
    defendant displayed a firearm for the purpose of threatening a victim – conduct
    that was accompanied by verbal threats to the effect that ―if you step out here, you
    see what I got‖ – was sufficient to demonstrate the defendant‘s reliance on the
    operability of the firearm. 
    Id. Similarly, this
    court has held in other cases that
    evidence of operability was sufficient where: one defendant was ―waving his gun‖
    while a second defendant ―stuck a gun into [the victim‘s] back‖; a defendant was
    seen ―displaying a gun to back up his demands‖; and a defendant was identified
    40
    Operability is no longer an element of CPWL. See Snell v. United States,
    
    68 A.3d 689
    , 692 n.4 (D.C. 2013).
    97
    ―wield[ing a] sawed-off shotgun in a menacing manner, knocking on the car
    window and waving it at [the victims].‖ Peterson v. United States, 
    657 A.2d 756
    ,
    763 (D.C. 1995); Bartley v. United States, 
    530 A.2d 692
    , 693-94 (D.C. 1987);
    Morrison v. United States, 
    417 A.2d 409
    , 413 (D.C. 1980).
    In those cases, the inference of the assailants‘ reliance on their weapons‘
    operability rested on reasoning that, through their display of the weapons, the
    assailants ―intended that their victims believe[] that the weapons were capable of
    being discharged.‖ 
    Bartley, 530 A.2d at 698
    . There is no such evidence in this
    case. During the period of time when Beaver was supposed to commit the murders
    personally, he never indicated that he would use his 9mm. And once Beaver
    persuaded Alphonce Little to carry out the shootings, Beaver did not offer Little
    the use of his 9mm; instead, Beaver stood by while Little and Dwayne Wright
    retrieved a different gun from inside Wright‘s house.
    This set of circumstances does not support an inference of operability. Price
    v. United States, 
    813 A.2d 169
    , 173 (D.C. 2002) (evidence was insufficient to
    support CPWL conviction where defendant held a weapon at his side while his
    companions shot and killed their victim because ―(1) the witnesses testified that
    98
    Price never pointed his weapon at anyone; and (2) he was never left on his own to
    control the victim without the assistance of his cohorts, who clearly had operable
    weapons.‖). In this case, like in Price, ―[t]he government simply failed to present
    evidence establishing either that [Beaver] fired his weapon, pointed it, or otherwise
    affirmatively displayed a belief that his weapon was operable[, and] the evidence
    here tends to dispel the notion that [Beaver‘s] weapon could fire.‖ 
    Id. Therefore, we
    vacate Beaver‘s CPWL judgment of conviction.
    F. Cooper’s Conviction: Laquanda Johnson Murder Under Pinkerton
    Cooper makes a multi-pronged attack on his conviction for the premeditated
    murder of Laquanda Johnson under a Pinkerton theory of liability. First, he argues
    that the murder occurred while he was in prison and that he had no control or
    influence over the actions of those directly involved. Therefore, the murder was
    not reasonably foreseeable to him as required for Pinkerton liability. Second, he
    argues that the application of this form of liability was unfair to him, and violated
    his due process rights on the facts of this case, because ―it [was] based on a
    charged ‗conspiracy‘ that [was] far too broad to support the application of a
    99
    vicarious liability theory.‖41    Finally, his brief implicitly argues that he suffered
    from selective prosecution with regard to this particular charge.42
    In determining whether a coconspirator may be held liable for commission
    of a substantive offense that the defendant did not directly commit, the government
    must prove ―that an agreement existed, that a substantive crime was committed by
    a co-conspirator in furtherance of that agreement, and that the substantive crime
    was a reasonably foreseeable consequence of the agreement between the
    conspirators.‖ Collins v. United States, 
    73 A.3d 974
    , 982 (D.C. 2013). The
    government is not ―required to establish that the co-conspirator actually aided the
    perpetrator in the commission of the substantive crime, but only that the crime was
    committed in furtherance of the conspiracy.‖ 
    Wilson-Bey, 903 A.2d at 840
    (citing
    
    Pinkerton, 328 U.S. at 646-47
    ).
    41
    Cooper connects this claim to his arguments that the evidence of a single
    conspiracy as charged was legally insufficient and the conspiracy charge itself was
    overbroad, arguments which we 
    rejected supra
    .
    42
    Considering his selective prosecution argument, we conclude that Cooper
    has not met his ―heavy burden‖ to establish that ―(1) others similarly situated were
    not prosecuted, and (2) the selective prosecution being complained of was
    improperly motivated, i.e., it was based on an impermissible consideration such as
    race or on a desire to prevent the exercise of constitutional rights.‖ Fedorov v.
    United States, 
    600 A.2d 370
    , 377 (D.C. 1991) (emphasis omitted).
    100
    Here, the conspiracy among Cooper and other members of the 22nd Street
    Crew between 2003 and 2006 included the agreement to obstruct justice, and the
    evidence showed that the coconspirators pursued that goal during the period of
    time leading up to Cooper‘s 2006 trial. The record shows that Cooper personally
    approached Laquanda Johnson and unsuccessfully bribed her with drugs and
    money in an attempt to influence Kyara Johnson‘s testimony at that trial. The
    evidence also revealed that Cooper contacted multiple gang members in order to
    persuade the sisters (particularly Kyara) to change their statements and some of
    these efforts contemplated the use of force.
    Moreover, there was evidence to show that the conspiracy to obstruct justice
    and prevent the Johnson sisters from doing further damage to the 22nd Street Crew
    did not end after Cooper‘s 2006 conviction. Alphonce Little testified that he
    murdered Laquanda, and intended to murder Kyara, because they might testify in
    the future against ―[a]nybody around 22nd Street, it could [be] me.‖ Little stated
    that because the sisters ―told on a murder[, t]hey could have told on me selling
    drugs [or] whatever.‖ Because appellants in this case had yet to be charged with
    conspiracy, and appellants other than Cooper had yet to be charged for the
    Terrence Jones murder-Richard Queen assault, it was foreseeable that the Johnson
    101
    sisters would continue, notwithstanding Cooper‘s conviction, to have the potential
    to harm the gang.43
    Furthermore, the conspiracy charged in this case also encompassed the goal
    of killing ―snitches‖ whose actions demonstrated ―interests [that] were contrary to
    those of the defendants and their associates.‖ In accordance with the overarching
    ―rule‖ enforced by the 22nd Street Crew that violence was to be inflicted on
    ―snitches,‖44 it was foreseeable that the Johnson sisters, by cooperating with the
    government, would be subject to retaliation by the members of the 22nd Street
    Crew who had entered into the charged conspiracy. When Little, Beaver, and
    fellow 22nd Street Crew member Dwyane Wright discovered that the sisters had
    returned to 22nd Street, they determined, in accordance with the retaliatory goal of
    the conspiracy, that the sisters should be killed because of their cooperation with
    the government.
    43
    For example, Kyara‘s testimony in the instant case about appellant Tann‘s
    and appellant Arnette‘s involvement in the Terrence Jones murder demonstrated
    the continuing threat that Kyara, helped by her sister‘s support, posed to members
    of the 22nd Street Crew and the coconspirators in this case.
    44
    Former gang member Andre McDuffie testified that ―[i]f someone was to
    cooperate [with the government]‖ that ―there would be violence inflicted.‖
    Alphonce Little testified that an ―automatic‖ rule of the crew was ―[d]on‘t snitch,‖
    which ―[came] with the territory of the game,‖ and that nobody who the gang knew
    to be a snitch ever came back to 22nd Street.
    102
    The fact that Cooper was in jail at the time of Laquanda Johnson‘s murder
    does not relieve him of liability under Pinkerton. Gatlin v. United States, 
    925 A.2d 594
    (D.C. 2007) provides a useful framework for analyzing Cooper‘s claim. In
    Gatlin, the defendant, who was incarcerated at the time of the murder of a
    government witness by his coconspirator, challenged the admissibility of the
    murdered witness‘s grand jury testimony under the forfeiture-by-wrongdoing
    doctrine.45 We held that ―[i]t was reasonably foreseeable that intimidation of and
    threats to witnesses could result in the murder of a witness.‖ 
    Id. at 600.
    The facts
    of Gatlin showed that the defendant, while in prison, communicated with his
    associates about disposing of witnesses and, much like the facts of this case,
    pressuring government cooperators ―to change their story.‖ 
    Id. at 598.
    Taken together, the evidence pertaining to the coconspirator‘s goals of
    obstructing justice and inflicting violence upon snitches – persons with interests
    contrary to those of the 22nd Street Crew members – demonstrated that Laquanda
    Johnson‘s murder was reasonably foreseeable to Cooper, despite the fact that he
    45
    The same forfeiture-by-wrongdoing issue as applied to statements by
    Laquanda Johnson is analyzed infra.
    103
    was in jail at the time. Little‘s act of murdering Laquanda was within the scope of
    the conspiracy to obstruct justice by preventing government cooperators, such as
    Laquanda and Kyara, from testifying against the 22nd Street Crew, and by
    retaliating with violence against persons who collaborated with the government
    against the gang. 
    Collins, 73 A.3d at 982-84
    ; Roberson v. United States, 
    961 A.2d 1092
    , 1095 (D.C. 2008); 
    Gatlin, 925 A.2d at 600
    . We further conclude that there
    was nothing about the breadth or nature of the conspiracy charged that made
    Pinkerton liability unfair to Cooper.
    VIII. Procedural and Evidentiary Issues Related to the Conspiracy and
    Appellants’ Joint Trial
    A. Cooper’s Prior Convictions
    Appellants make several arguments involving the admission of Cooper‘s
    2006 convictions for the Terrence Jones murder-Richard Queen assault. First,
    Tann and Arnette contend that the trial court erred when it refused to sever their
    trials from Cooper‘s after it became apparent that both the government and Cooper
    intended to put evidence of Cooper‘s prior convictions in front of the jury.
    Second, Tann, Arnette, and Cooper make the evidentiary argument that the prior
    convictions should not have been admitted against each of them. The government
    admits evidentiary error as to Tann and Arnette.
    104
    Before trial, the government indicated its intent to admit the convictions
    because they would provide evidence as to the conspiracy count of (1) the Terrence
    Jones murder and Richard Queen assault, which were represented in a series of
    overt acts listed in the indictment, and (2) partial motive for the murder of
    Laquanda Johnson by appellants‘ coconspirator, Alphonce Little, who sought
    revenge against the Johnson sisters for their cooperation with the government in
    Cooper‘s 2006 trial that led to his conviction and imprisonment. Cooper wanted
    the convictions in evidence because, as we have 
    explained supra
    , a significant part
    of his defense against the Laquanda Johnson murder charge was based on the fact
    that he had been convicted of and sentenced for the Terrence Jones murder in 2006
    and was in jail at the time of her killing. Therefore, he intended to argue to the
    jury that he had known nothing about, and had no involvement with, her death.
    Tann and Arnette pointed out in pretrial hearings that this trial was to feature
    testimony from some of the same witnesses that had testified at Cooper‘s 2006
    trial. They argued that when the jury found out about Cooper‘s convictions, it
    would necessarily conclude that the government‘s witnesses in this case were
    credible because a previous jury had found them so. The trial court disagreed with
    105
    appellants‘ contention and found that an instruction would be sufficient to ensure
    the jury made proper use of the convictions.
    The government, Cooper, and Arnette, mentioned Cooper‘s 2006 conviction
    for the Terrence Jones murder during opening statements.           The government
    informed the jury of the conviction in the context of explaining why Arnette and
    Tann were charged with crimes related to the Terrence Jones murder-Richard
    Queen assault, but Cooper was not.         Cooper mentioned the conviction, but
    indicated that the prior verdict was ―incorrect.‖ Arnette stated that another person
    – obviously referencing Cooper – had already been convicted of the murder and
    that there were witnesses in Cooper‘s trial who had testified that Arnette ―didn‘t do
    anything‖ during the incident.    No further mention was made of the convictions
    until Cooper took the stand in his defense approximately six months later.
    During Cooper‘s testimony, the government impeached him with his prior
    convictions, including those related to the Terrence Jones murder-Richard Queen
    assault. The court gave the jury a standard instruction that prior convictions were
    to be considered for credibility purposes only.
    106
    In final jury instructions, after consultation with the parties, the court further
    instructed the jury that:
    In addition to considering [Cooper‘s Terrence Jones
    murder conviction] when assessing Mr. Cooper‘s
    credibility as a witness, you may also properly consider it
    in determining whether the government has met its
    burden of proof with respect to [the overt act charged in
    the indictment pertaining to the Terrence Jones murder]
    . . . . You are not required to accept the fact that Mr.
    Cooper‘s prior conviction for this offense is conclusive
    evidence that the government has met its burden of proof,
    but, instead, you may give it[,] like every other piece of
    evidence, whatever weight you feel it‘s entitled to
    receive. Moreover, you may not consider the prior
    conviction as establishing the truthfulness of any of the
    witnesses who testified in the prior trial.
    The trial court did not distinguish between appellants when describing how this
    evidence could be used by the jury. During closing arguments, the government
    briefly talked about the prior convictions, again as a reminder to the jury why
    Cooper was not charged with Terrence Jones‘s murder, but did not use the
    convictions to argue guilt.
    1. Error in Admitting Cooper’s Convictions Against Tann and
    Arnette
    The admission of Cooper‘s conviction against appellants other than Cooper
    for the truth of the matters asserted, as proof of an overt act of the conspiracy with
    107
    which they were charged, was constitutional error as long recognized by case law
    and the commentary to Federal Rules of Evidence 803 (22), the federal hearsay
    exception for prior judgments of conviction.46 In 
    Kirby, 174 U.S. at 59
    , over a
    century ago, the Supreme Court held that one defendant‘s prior conviction may not
    be admitted as evidence against his codefendants.          Numerous cases followed
    recognizing that holding. See, e.g., United States v. Vandetti, 
    623 F.2d 1144
    , 1148
    (6th Cir. 1980) (finding a Confrontation Clause violation); State v. Tollardo, 
    275 P.3d 110
    , 116 (N.M. 2012) (same); cf. Bisaccia v. Attorney Gen. of N.J., 
    623 F.2d 307
    , 311-12 (3d Cir. 1980) (finding a due process violation). Although there is
    conflicting authority as to whether this type of error offends the Confrontation
    Clause,47 or whether the error affronts fundamental notions of due process,48 or
    whether it is a violation of both,49 the error is clearly of constitutional dimension.
    46
    Fed. R. Evid. 803 (22) advisory committee‘s note: ―[T]he exception does
    not include evidence of the conviction of a third person, offered against the
    accused in a criminal prosecution to prove any fact essential to sustain the
    judgment of conviction. A contrary position would seem clearly to violate the
    right of confrontation.‖ (citing Kirby v. United States, 
    174 U.S. 47
    (1899)).

    108
    Therefore, the evidentiary error must be analyzed under the constitutional
    harmless error standard as articulated in Chapman v. California, 
    386 U.S. 18
    (1967).   We may affirm only if we find that ―the government presented
    overwhelming evidence of guilt,‖ or more importantly here, if ―it is clear beyond a
    reasonable doubt that a rational jury would have found the defendant[s] guilty
    absent the error.‖ (Eric) Gardner v. United States, 
    999 A.2d 55
    , 58 (D.C. 2010)
    (quoting (Edwin) Smith v. United States, 
    966 A.2d 367
    , 391 (D.C. 2009)).
    We also note that the error had a potential effect on appellants‘ severance
    claims. While plausible, Tann and Arnette‘s argument that the prior convictions
    would enhance the credibility of the government‘s witnesses had little practical
    force, at least at the outset of trial. The government‘s witnesses called to give
    evidence about Tann‘s and Arnette‘s participation in Terrence Jones‘s murder and
    Richard Queen‘s assault gave often inconsistent and occasionally exculpatory
    testimony about Tann and Arnette at both trials. Queen testified in both trials that
    (…continued)
    trenches upon a defendant‘s due process right to have the government prove every
    element of the offense with which he is charged. . . . Second . . . it trenches upon a
    defendant‘s right to confront his accusers.‖).
    109
    Tann had no involvement in his assault or the murder of Terrence Jones.
    Similarly, Shaunta Armstrong attested that Arnette was present at the scene of the
    crime but did nothing in the attack on Terrence Jones or Queen. Donald Matthews
    gave testimony that was very damaging to Tann (identifying him as Queen‘s
    shooter), but highly exculpatory to Arnette (indicating that he was not involved in
    the joint attack).
    Therefore, standing alone, the admission of Cooper‘s convictions against
    Cooper would have had little impact on the other appellants.50 However, when the
    trial court erred by allowing admission of the convictions for substantive purposes
    against Tann and Arnette, it also revitalized appellants‘ arguments that severance
    from Cooper‘s trial was required. Consequentially, in addition to analyzing the
    evidentiary error under the Chapman standard for harmlessness, we must
    simultaneously look to see whether the joinder of Tann and Arnette with Cooper
    resulted in ―the most compelling prejudice‖ that would constitute reversible error.
    50
    Even if appellants had been tried separately, Cooper‘s convictions still
    would very likely have been admitted as evidence of Alphonce Little‘s partial
    motive to kill Laquanda Johnson for both the conspiracy count and the substantive
    counts involving her murder. If properly handled at separate trials, the conviction
    simply would not have been admitted as substantive evidence against appellants
    other than Cooper – which is also what should (and presumably would) have
    occurred in this trial had the trial judge not failed to catch the constitutional error
    that flowed from his instruction.
    110
    Workman v. United States, 
    15 A.3d 264
    , 266 (D.C. 2011) (quoting Bailey v. United
    States, 
    10 A.3d 637
    , 642 (D.C. 2010)).
    2. Harmlessness
    First, the trial court‘s instruction limited the jury‘s consideration of the
    convictions to the overt act in the conspiracy count describing the Terrence Jones
    murder. The potential prejudicial effect of the error was greatly reduced, if limited
    to that overt act. There were thirty-three overt acts listed in the conspiracy count,
    many of which were easily proven by substantial evidence, and only one of which
    needed to have been committed by a single defendant and proven beyond a
    reasonable doubt in order to establish the conspiracy. Gilliam v. United States, 
    80 A.3d 192
    , 208 (D.C. 2013). We recognize, as we have repeatedly done in the past,
    that jurors are presumed to follow instructions. See Jordan v. United States, 
    18 A.3d 703
    , 709 (D.C. 2011).
    However, the overt acts listed in the conspiracy count that pertained to the
    Terrence Jones-Richard Queen incident largely mirrored the substantive counts of
    murder, assault, and robbery with which Tann and Arnette were charged relating to
    the same event, and of which Cooper admitted that he had been convicted.          To
    111
    pretend that there was no danger that the jury could have considered Cooper‘s
    conviction as to both the conspiracy count and the substantive counts is to ignore
    the reality that instructions are not always effective. See Battle v. United States,
    
    630 A.2d 211
    , 225 (D.C. 1993) (requiring ―mental gymnastics‖ of the jury may
    well be ―troublesome in some circumstances‖); (Oliver) Clark v. United States,
    
    593 A.2d 186
    , 193 (D.C. 1991) (―Jurors are, of course, presumed to obey the
    court‘s instructions, but we have recognized that this doctrine has its limits, for no
    juror, no matter how conscientious, can do the impossible.‖) (citations omitted).
    Even so, after closely examining the error in the context of the evidence
    presented in this case, we find that it was harmless beyond a reasonable doubt
    under Chapman. First, while the trial court‘s instruction was flawed in that it
    violated Kirby, it did clearly inform the jury that it was not to ―consider the prior
    conviction as establishing the truthfulness of any of the witnesses who testified in
    the prior trial,‖ which is our principal concern on appellate review, and was the
    appellants‘ worry throughout the trial (and is again on appeal) with regard to the
    prior convictions.
    112
    More importantly, because of the nature of the testimony of the
    government‘s witnesses who testified about the Terrence Jones-Richard Queen
    incident, we are convinced that Cooper‘s convictions had no prejudicial impact on
    appellants Tann or Arnette. It was clear that the witnesses who testified at both
    trials, while generally giving testimony very damaging as to Cooper, had given
    highly contradictory, and often favorable, testimony as to Tann and Arnette.51
    Therefore, we see no way that the jury could have considered Cooper‘s convictions
    in a manner harmful to Tann and Arnette, other than as proof of the overt act, even
    had it ignored or misunderstood the credibility portion of the trial court‘s
    instruction.
    51
    For the same reasons, the government‘s case was not ―overwhelming‖ as
    to Tann and Arnette on the Terrence Jones-Richard Queen related offenses.
    Although we have found error harmless beyond a reasonable doubt where the
    government‘s evidence was otherwise ―overwhelming,‖ see, e.g., (James) Hill v.
    United States, 
    858 A.2d 435
    , 447 (D.C. 2004), it is not necessary that the evidence
    be so in every case where reversal is unwarranted, if the significance of the error is
    sufficiently minimal so as to satisfy the constitutional standard. See Fields v.
    United States, 
    952 A.2d 859
    , 866 (D.C. 2008) (reversing where the court could not
    say that the constitutional error did not ―contribute‖ to the verdict because of the
    materiality of the error and where the evidence of the defendant‘s guilt was not
    overwhelming); McDonald v. United States, 
    904 A.2d 377
    , 382 (D.C. 2006)
    (examining both the ―centrality‖ of the error and the ―less than overwhelming
    strength‖ of the government‘s case when performing a Chapman analysis).
    113
    Further bolstering our conclusion is the fact that, despite repeatedly
    mentioning Cooper‘s prior convictions in the context of explaining its charging and
    prosecutorial strategy, the government never argued for the guilt of any appellant
    on the basis of those convictions. Paige v. United States, 
    25 A.3d 74
    , 84 (D.C.
    2011) (weighing ―the fact that the prosecution in no way advanced [the conviction]
    as evidence of appellant‘s guilt‖ when assessing prejudice). In light of these
    circumstances, and in view of the fact that the jury appears to have carefully parsed
    through the complicated testimonial evidence – acquitting Tann and Arnette both
    of the most serious first-degree felony murder charges arising out of the incident –
    we can say that there is no ―reasonable possibility that the evidence complained of
    might have contributed‖ to Tann‘s and Arnette‘s convictions. 
    Chapman, 386 U.S. at 23
    . Instead, we are confident that ―the guilty verdict[s] actually rendered in this
    trial [were] surely unattributable to the error.‖ Ellis v. United States, 
    941 A.2d 1042
    , 1049 (D.C. 2008) (emphasis omitted) (quoting Sullivan v. Louisiana, 
    508 U.S. 275
    , 279 (1993)). For the same reasons, we find that Tann and Arnette were
    not ―manifestly prejudiced‖ by their joinder throughout this trial. See McAdoo v.
    United States, 
    515 A.2d 412
    , 420 (D.C. 1986).52
    52
    Appellants Harris, Rushing, and Beaver do not raise claims related to
    Cooper‘s prior conviction. However, they were similarly situated with Tann and
    Arnette to the extent that they were charged with the conspiracy count that listed
    (continued…)
    114
    3. Admission Against Cooper
    Cooper argues that the trial court committed evidentiary error against him by
    admitting his prior judgment of conviction into evidence for the truth of the matter
    as an exception to the rule against hearsay.       We have not yet addressed the
    propriety of adopting Fed. R. Evid. 803 (22).53 Because any error as to Cooper
    was clearly harmless, as he was not charged with the substantive offenses
    (…continued)
    the events of the Terrence Jones-Richard Queen incident as overt acts of the
    conspiracy. And the trial court‘s instruction permitted the jury to consider
    Cooper‘s prior convictions against each of them as well as Tann and Arnette.
    Therefore, the evidentiary error extended to their cases, and we invoke our
    discretion to review the impact of that error. See, e.g., 
    Gilliam, 80 A.3d at 205-06
    ;
    Walker v. United States, 
    982 A.2d 723
    , 738 (D.C. 2009). Nevertheless, any
    argument about prejudice to Harris, Rushing, or Beaver by way of the admission of
    Cooper‘s prior conviction is even weaker than it is for Tann and Arnette because
    Harris, Rushing, and Beaver were not charged with the substantive offenses arising
    out of the Terrence Jones-Richard Queen incident. Consequently, the error as to
    those appellants was clearly harmless beyond a reasonable doubt.
    53
    Many state courts have had occasion to adopt the federal rule. See, e.g.,
    Flood v. Southland Corp., 
    616 N.E.2d 1068
    , 1074 (Mass. 1993) (―Substantially
    more than one-half of the States have adopted rules of evidence similar to Fed. R.
    Evid. 803 (22).‖); State v. Scarbrough, 
    181 S.W.3d 650
    , 660 (Tenn. 2005)
    (―Allowing the prosecution to use a final conviction as evidence in [a criminal]
    trial is consistent with [the state and federal hearsay exceptions] as well as with the
    reality that the conviction is final and may have probative value.‖) (citing United
    States v. Pelullo, 
    14 F.3d 881
    , 888 (3d Cir. 1994)).
    115
    underlying the Terrence Jones-Richard Queen incident, we need not reach that
    question here.
    B.          Tann’s Severance Argument Unrelated to Cooper’s Prior
    Conviction
    Appellant Tann makes the separate argument, for the first time on appeal,
    that severance was warranted by the size of the case and the amount of ―spillover‖
    evidence that made it impossible for the jury ―not to have been influenced by the
    sheer volume and interrelatedness of the testimony.‖       The argument is rooted in
    Tann‘s claim that much of the evidence of his codefendants‘ ―bad acts‖ would not
    have been admissible had he been tried separately.
    ―The general rule is that defendants charged with jointly committing a crime
    are to be tried together.‖ 
    McAdoo, 515 A.2d at 420
    . Our decision in Castillo-
    Campos is instructive when considering Tann‘s claim here. In Castillo-Campos,
    this court concluded that because all three defendants were charged with
    conspiracy, they were ―incorrect in arguing that evidence pertaining to their co-
    defendants did not pertain to them or had only an improper spillover 
    effect.‖ 987 A.2d at 493
    . We recited the established rule that ―[i]n a conspiracy case, wide
    latitude is allowed in presenting evidence, and it is within the discretion of the trial
    116
    court to admit evidence which even remotely tends to establish the conspiracy
    charged.‖ 
    Id. (quoting (Kevin)
    Holmes v. United States, 
    580 A.2d 1259
    , 1268
    (D.C. 1990)).
    Obviously, there was extensive testimony and evidence at trial presented
    about the 22nd Street Crew and conspiracy count as charged in the indictment;
    however, much of it also directly involved Tann. The evidence showed that he
    was among the leaders and most active members of the 22nd Street Crew. Tann
    was heavily involved in the illegal drug trafficking that was the bulk of the
    uncharged offenses elicited by the government and directly involved in three of the
    four murders.
    As in Castillo-Campos, it cannot be said that the majority of other
    appellants‘ ―bad acts‖ did not pertain to Tann or had an improper ―spillover effect‖
    on the disposition of his case. And even assuming that some of the evidence might
    not have been independently admissible in a separate trial against Tann, severance
    would not have been required. See Johnson v. United States, 
    596 A.2d 980
    , 987
    (D.C. 1991) (―An appellant does not suffer [manifest] prejudice merely because a
    significant portion of the government‘s evidence admitted at trial is applicable only
    to his codefendants.‖) (internal quotation marks omitted).
    117
    Likewise, Tann‘s claim that the evidence was too unwieldy for the jury to
    keep straight, or that the jury likely grouped the various codefendants‘ actions
    together in its decision-making, finds no support in the record. Before opening
    statements and prior to deliberations, the court instructed the jury to consider each
    offense separately. See Mitchell v. United States, 
    985 A.2d 1125
    , 1137 (D.C.
    2009). In addition, the jurors deliberated at length and acquitted Tann of several
    charges, actions which demonstrated a careful analysis of the merits of each
    charge. See 
    Castillo-Campos, 987 A.2d at 493
    (noting that the jury acquitted
    defendants of several charges when finding that it was able to understand and
    process the evidence against each codefendant). In short, Tann has provided no
    evidence of ―manifest prejudice‖ that would have required severance of his case.
    Accordingly, the trial court did not commit error, let alone plain error.
    C. Laquanda Johnson’s Statements Admitted Under a Forfeiture-by-
    Wrongdoing Theory
    Appellants Cooper, Beaver, and Tann claim that the trial court erred by
    admitting several statements by Laquanda Johnson under a forfeiture-by-
    wrongdoing theory. Specifically, Laquanda made a number of statements to her
    sister, Shaunta Armstrong, and her mother, Karen Bolling, regarding her desire for
    118
    Kyara Johnson not to testify against Cooper out of fear of retaliation by the 22nd
    Street Crew. Bolling testified that Laquanda reported to her the contents of a
    conversation that she had with Cooper in which Cooper offered her drugs and
    money to keep Kyara off the stand. Further, Laquanda told her mother that Tann
    had approached her and made veiled threats about what would happen to her if
    Kyara testified.      Bolling also reported that Laquanda informed her that
    immediately following the Terrence Jones murder, Cooper had said to Laquanda,
    ―What‘s up L.J.? . . . I just did a nigger up the street.‖
    In the course of ruling on motions to suppress, the trial court found that these
    statements fit within the forfeiture-by-wrongdoing theory of admissibility because
    (1) Laquanda Johnson was murdered, in part, because appellants‘ coconspirator
    Alphonce Little wanted to eliminate Laquanda as a future government witness, (2)
    her killing was within the scope and in furtherance of the conspiracy, and (3)
    Little‘s action was reasonably foreseeable to all appellants, including Cooper,
    despite the fact that he was in jail at the time of her murder after being convicted
    for killing Terrence Jones.
    119
    ―Under the forfeiture-by-wrongdoing doctrine, a defendant forfeits his Sixth
    Amendment right to be confronted by a witness against him, as well as his
    objection to the introduction of hearsay, if he wrongfully procured the
    unavailability of that witness with the purpose of preventing the witness from
    testifying.‖ 
    Roberson, 961 A.2d at 1095
    ; Devonshire v. United States, 
    691 A.2d 165
    , 168 (D.C. 1997). Of course, this theory is not limited to situations where the
    defendant personally made the witness unavailable. ―[I]f the defendant conspired
    with another to prevent the witness from testifying, forfeiture ensues whether it
    was the defendant himself or another co-conspirator who made the witness
    unavailable so long as the actor‘s misconduct ‗was within the scope of the
    conspiracy and reasonably foreseeable to the defendant.‘‖ 
    Roberson, 961 A.2d at 1095
    (quoting United States v. Carson, 
    455 F.3d 336
    , 364 (D.C. Cir. 2006)); see
    also Jenkins v. United States, 
    80 A.3d 978
    , 994-95 (D.C. 2013). We review the
    court‘s rulings on admissibility under the forfeiture-by-wrongdoing theory for
    abuse of discretion. 
    Jenkins, 80 A.3d at 989
    .
    We find no abuse of discretion in the trial court‘s handling of this issue. The
    same conspiracy law principles that justified the use of Pinkerton liability to hold
    Cooper accountable for the substantive offense of Laquanda Johnson‘s murder
    120
    similarly validated the trial court‘s evidentiary finding here. The evidence showed
    that Laquanda was murdered by Alphonce Little during the course, and in
    furtherance, of the conspiracy to obstruct justice and prevent witnesses such as
    Laquanda from testifying against the 22nd Street Crew.
    Laquanda Johnson had significant value to the government as a witness,
    even after Cooper had been convicted of Terrence Jones‘s murder in 2006. As
    Little testified, she had information about illegal activities on 22nd Street by the
    22nd Street Crew members.54 Furthermore, Laquanda‘s statements about Tann‘s
    and Cooper‘s efforts to obstruct justice, in order to influence her sister‘s testimony
    and therefore the outcome of Cooper‘s trial could have been foreseeably admitted
    by the government in a future trial against appellants on the conspiracy and
    obstruction of justice offenses, with which no appellant had yet been charged as of
    the time of Cooper‘s 2006 conviction. As a consequence, Laquanda‘s murder was
    reasonably foreseeable to appellants as part of their conspiracy to inflict violence
    54
    On cross-examination, Cooper‘s defense counsel attempted to elicit from
    Little that ―the only reason‖ that Laquanda was killed was in retaliation for her past
    cooperation with the government, as opposed to any future threat to the gang.
    Little disagreed with the premise of Cooper‘s defense counsel‘s questions and
    testified that the murder was also because ―[the sisters] could have been telling on
    somebody [in the gang], telling on any other thing.‖
    121
    on persons, such as government witnesses, with interests contrary to theirs.

    ; 
    Roberson, 961 A.2d at 1096-97
    ; 
    Gatlin, 925 A.2d at 600
    .
    Therefore, we find no abuse of discretion by the trial court.55
    D. The Trial Court’s Finding of a Predicate Conspiracy
    Tann and Arnette dispute the validity of the trial court‘s determination that a
    predicate conspiracy had been established to justify admission of coconspirator
    55
    Cooper‘s brief makes the related argument that another of Laquanda
    Johnson‘s statements admitted into evidence under the forfeiture-by-wrongdoing
    theory was inadmissible because it was double hearsay. Laquanda told her sister,
    Shaunta Armstrong, that 22nd Street Crew member Eric Dreher stated to Laquanda
    that she should ―get Kyara off of 22nd Street and never come back‖ because
    Cooper had ―goons out there‖ looking for her. Although Cooper is correct that this
    testimony by Shaunta was double hearsay, there were hearsay exceptions at both
    levels. As 
    discussed supra
    , Laquanda‘s statements to Shaunta were admissible
    because of forfeiture-by-wrongdoing, which acts as a waiver to both Confrontation
    Clause and hearsay objections to admissibility. Dreher‘s statements to Laquanda
    were admissible under the coconspirator statement exception to the hearsay rule.
    As the trial judge found, there was sufficient independent, nonhearsay evidence
    presented that Dreher was a member of the 22nd Street Crew and a member of the
    conspiracy charged in this case. This evidence came in the form of testimony by
    former gang members Andre McDuffie, Donald Matthews, Devin Evans, Travis
    Honesty, and Alphonce Little that Dreher was a high-ranking gang member who
    recruited appellant Harris and others to be members of the crew, sold drugs with
    other 22nd Street Crew members, and was influential in the gang because of his
    willingness to engage in ―acts of violence‖ on behalf of the crew. Additionally,
    Dreher‘s statements could have been reasonably viewed as furthering the
    conspiracy‘s goal of obstruction of justice by wrongfully discouraging Laquanda
    from testifying at Cooper‘s 2006 trial. See Butler v. United States, 
    481 A.2d 431
    ,
    439 (D.C. 1984).
    122
    statements in furtherance of that conspiracy. At the outset of trial, given the
    number of (charged and uncharged) coconspirators that the government alleged to
    have participated in the activities of the 22nd Street Crew and the charged
    conspiracy, the trial judge was concerned, with justification, about tightly
    controlling the admission of coconspirator statements. See 
    Butler, 481 A.2d at 439
    (holding the trial judge responsible for determining the admissibility of
    coconspirators‘ statements in order to avoid ―the danger that the jury might convict
    on the basis of these statements without first dealing with the admissibility
    question‖).
    In order to better monitor the showing of a predicate conspiracy, the court
    ordered the government to ―bifurcate‖ its case-in-chief by opening with a
    ―conspiracy‖ phase, followed by a ruling from the court as to whether the
    government had met its burden of establishing a predicate conspiracy and the
    identities of the coconspirators, before the government moved into a ―substantive‖
    phase of its case wherein coconspirator statements could be admitted as evidence.
    After hearing from the gang ―insiders‖ previously discussed (Andre McDuffie,
    Donald Matthews, Devin Evans, and Alphonce Little), and police personnel who
    testified about illegal drug activity involving appellants, the court found that the
    123
    existence of a predicate conspiracy had been established for purposes of the
    hearsay issue.
    Specifically, the trial court found:
    [There] was a conspiracy, among other things, to
    purchase, package and [resell] illegal narcotics, to use
    weapons and violence to safeguard the conspiracy and
    retaliate against those who are not members of the
    conspiracy[] and who had attempted to invade the
    conspiracy‘s turf, and to promote the reputation of the
    conspiracy and its members in the 22nd Street
    neighborhood. [56]
    56
    The trial judge found the existence of a predicate conspiracy that was
    similar, but not identical to the one charged in Count 1 of the indictment, i.e., that
    appellants and others agreed ―to obstruct justice and to assault and kill anyone
    whose interests were contrary to those of the defendants and their associates.‖
    Instead, the trial judge appears to have found, for purposes of the evidentiary issue,
    that the goals of the predicate conspiracy tracked closely with the ―Objects of the
    Conspiracy‖ as listed on the second page of the superseding indictment: to
    ―retaliate for acts of violence perpetrated against the conspiracy and its members
    . . . protect illicit profits generated by the involvement of the conspiracy‘s members
    and associates in acts involving . . . trafficking in controlled substances . . . and . . .
    protect the conspiracy and its members . . . from conviction for criminal charges,
    and to retaliate against anyone who assisted law enforcement officials in the
    investigation into and prosecution of members of the conspiracy and their
    associates.‖ The trial court did not err in taking this approach to his findings.
    ―The conspiracy that forms the basis for admitting coconspirators‘ statements need
    not be the same conspiracy for which the defendant is indicted.‖ United States v.
    Acre, 
    997 F.2d 1123
    , 1128 (5th Cir. 1993). Indeed, statements in furtherance of a
    conspiracy may be admissible where there is no conspiracy charged in the
    indictment at all. United States v. Ayotte, 
    741 F.2d 865
    , 869 (6th Cir. 1984).
    124
    ―The trial court‘s decision to admit coconspirator testimony as nonhearsay
    will be upheld absent an abuse of discretion.‖ Harrison v. United States, 
    76 A.3d 826
    , 834 (D.C. 2013).       ―[A] coconspirator‘s out-of-court assertions may be
    admitted for their truth only if the judge finds it more likely than not that (1) a
    conspiracy existed, (2) the defendant had a connection with the conspiracy, and (3)
    the coconspirator made the statements during the course of and in furtherance of
    the conspiracy.‖ 
    Jenkins, 80 A.3d at 989
    -90. Appellants challenge the trial court‘s
    ruling as to the first two prongs of the coconspirator statement rule.
    Because the court‘s ruling came before the government put on its
    ―substantive‖ case, the judge did not have the benefit of the facts that went to the
    murder charges.57    Nevertheless, the judge made detailed findings as to each
    appellant and his membership in a conspiracy that are supported by the facts and
    not shown by Tann or Arnette to be clearly erroneous. 
    Id. at 989
    (accepting the
    factual findings of the trial court unless they are clearly erroneous when reviewing
    under an abuse of discretion standard). The trial judge found that the goals of the
    conspirators ―were accomplished through the establishment of [and] adherence to
    57
    In our opinion, this evidence would have significantly strengthened an
    already well-reasoned ruling.
    125
    and enforcement of rules of the group by both threats and violence.‖ The judge‘s
    findings sufficiently established the associational connection between the different
    appellants, and their joint support of the drug trafficking activities of the 22nd
    Street Crew, including the maintenance of its base of operations through acts of
    violence, such that there was no abuse of discretion in his ruling on the existence
    of a predicate conspiracy.
    E. Rap Lyrics and Beaver’s Webpage
    At trial, the government introduced the following evidence against
    appellants: (1) a rap CD containing songs performed by Rushing and an unindicted
    coconspirator, Michael Smith; (2) rap lyrics written by Tann which were found and
    read to the jury by his wife, Tracey; and (3) the contents of a webpage that had
    been created and posted by Beaver. The court ruled that the statements contained
    within these items were made in furtherance of a conspiracy and admissible against
    all appellants. Appellants now appeal that ruling.
    After the court required the government to make extensive redactions to the
    material on the rap CD, the government played approximately twelve minutes of
    the Rushing-Smith songs. According to testimony, the songs were being sold and
    played openly on 22nd Street. The song lyrics made reference to ―The Deuce,‖
    126
    ―Deuce Mob,‖ and the ―Young Gunz,‖ all names affiliated with the 22nd Street
    Crew. The lyrics also referred to the gang nicknames of Rushing, Beaver, Cooper,
    and Arnette. Furthermore, the lyrics tended to glorify criminal activities that were
    part of the lifestyle of the 22nd Street Crew members, including drug dealing,
    killing government informants, and killing rivals.
    The government also called Tann‘s wife, Tracey, to give evidence about rap
    lyrics that were written by Tann. According to Tracey, the lyrics were part of a rap
    project for which Tann had commercial aspirations. Tann‘s lyrics included
    references to the 22nd Street Crew‘s nickname ―D.E.U.C.E.,‖ drug dealing, and
    violent crime against ―snitches.‖ Tann‘s lyrics also arguably made specific
    references to the details of the Leslie Jones murder that were relied on by the
    government in its closing argument as evidence of his culpability.58
    58
    Tann‘s lyrics read: ―Screamin‘ D.E.U.C.E. Allday Southside[.] I hail
    from Death Valley[.] Bang my first pistol deep in dog Alley.‖ In closing
    argument, the government argued that by these words Tann described the Leslie
    Jones murder where he murdered Jones with a gun and then ran down an alleyway
    near 22nd Street known as ―Dog Alley.‖ Tyrone Curry, a government witness,
    testified that he saw a man who looked like Tann running from the scene of the
    Leslie Jones shooting ―toward the dog alley on 23rd Street.‖
    127
    Finally, the government put on evidence of a ―Black Planet‖ webpage that
    was stipulated to have been created and published by Beaver.        The webpage
    featured pictures of Beaver making hand signs affiliated with the 22nd Street Crew
    and a message from Beaver describing himself as ―DEUCEDEUCEBANGA.‖
    Beaver implied on the webpage that he was ready to commit violence against any
    ―dudes‖ that he found to be ―snitchin.‖
    Appellants attack the admission of the rap lyrics sung by Rushing and
    Michael Smith on several grounds: (1) there was insufficient evidence that either
    Smith or Rushing authored the lyrics; (2) Smith was not a proven coconspirator,
    and therefore his performance and singing of the song lyrics could not have
    reflected statements made in the course of the conspiracy; (3) the lyrics to the
    songs themselves were not in furtherance of the conspiracy; and (4) even if
    otherwise admissible, the song lyrics were unfairly prejudicial.      Appellants‘
    primary complaint about Tann‘s lyrics and Beaver‘s webpage is that the statements
    were not made in furtherance of the conspiracy.
    1. Authorship of the Rap Lyrics on the CD
    ―A party may make an admission by adopting or acquiescing in the
    statement of another. Whether a party has adopted the statement of another is a
    128
    preliminary question of fact for the trial judge, which is determined by considering
    the context and the surrounding circumstances of the claimed adoption.‖ Harris v.
    United States, 
    834 A.2d 106
    , 116-17 (D.C. 2003) (citations, internal quotation
    marks, and alterations omitted). While this rule ―does not require an explicit
    statement of adoption,‖ it does require ―some manifestation of a party‘s intent to
    adopt another‘s statements, or evidence of the party‘s belief in the truth of the
    statements.‖ Bridges v. Clark, 
    59 A.3d 978
    , 986 (D.C. 2013).
    Here, the ―surrounding circumstances of the claimed adoption‖ are that
    Rushing and Michael Smith sang the lyrics to rap songs for the purpose of
    recording a CD that was available for purchase and played publicly. There was no
    evidence that Smith or Rushing actually wrote or produced the lyrics to the songs.
    Appellants argue that the lyrics were created solely for ―artistic,
    entertainment purposes,‖ and not as a truthful recitation of events on 22nd Street or
    the attitudes of either the producers or singers. While certainly these songs may
    have been a form of artistic entertainment to persons listening on 22nd Street,
    some entertainment is fictional and some is intended to be a retelling of true and
    actual events. And lyrics to any song may well be intended to relay the truth in the
    129
    eyes of the singer. As the government points out, in these songs, ―the lyrics were
    primarily in the first-person and described individuals, places, and activities
    specifically related to the 22nd Street Crew.‖ We find that these facts were
    sufficient foundation upon which to establish that ―there was an unambiguous
    assent‖ by Michael Smith and Rushing to the statements contained in the lyrics that
    they sang. See Blackson v. United States, 
    979 A.2d 1
    , 7 (D.C. 2009).
    2. Whether Michael Smith was a Coconspirator
    Michael Smith was identified as a member of the 22nd Street Crew by a
    number of the government‘s witnesses:          Donald Matthews, Devin Evans,
    Alphonce Little, Tracey Tann, Travis Honesty, and Darryl Travers. Honesty and
    Travers testified that Smith was a ―hustler‖ who sold narcotics on 22nd Street from
    2001 until 2007 or 2008. This testimony reasonably established Smith‘s
    membership in a conspiracy, at a minimum, among members of the 22nd Street
    Crew to sell illegal narcotics. Matthews‘s testimony that Smith was part of a group
    of men who were ―coming up‖ in the organization, no later than 2002, with other
    crew members such as Beaver, also established a reasonable basis from which the
    trial judge could infer Smith‘s agreement with and support of the more violent
    aspects of criminal activity within the 22nd Street Crew. The testimony of the
    former gang members acting as government witnesses was that members increased
    130
    their influence in the organization by committing acts of violence against rivals,
    snitches, and other persons at odds with the interests of the organization.
    Once the government showed that Michael Smith was a member of the
    predicate conspiracy for purposes of the hearsay exception, it was not required to
    show that he was still a member of the conspiracy later in time. See United States
    v. (Rodney) Moore, 
    651 F.3d 30
    , 90 (D.C. Cir. 2011) (―[O]nce a defendant
    becomes a member of a conspiracy, he remains a member until he affirmatively
    withdraws or the conspiracy ends. Therefore, once the government proves that a
    defendant was a member of an ongoing conspiracy, it has proven the defendant‘s
    continuous membership in that conspiracy unless and until the defendant
    withdraws.‖) (citation omitted). There was no evidence of withdrawal by Smith.
    Consequently, there was sufficient evidence reasonably to show that Smith sang
    the rap lyrics on the CD during his involvement in the predicate conspiracy.
    3. Statements in Furtherance of the Conspiracy
    Appellants‘ third argument is that ―the lyrics purportedly authored by
    Beaver and Tann and those sung by Rushing and Michael Smith were inadmissible
    because there is no evidence that they were written or sung in furtherance of the
    charged conspiracy.‖     In countering this argument, the government emphasizes
    131
    that the statements in the rap songs, in Tann‘s lyrics, and on Beaver‘s webpage,
    made reference to the 22nd Street Crew, the members of 22nd Street Crew who
    were part of the charged conspiracy, and ―the structure of the conspiracy and the
    importance of [the] members‘ continued participation and loyalty.‖ The core of
    the government‘s ―in furtherance‖ argument is:
    [G]iven that (1) the CD was sold on 22nd Street and was
    listened to by conspirators and non-conspirators alike, (2)
    the web page was open to public view on the internet,
    and (3) Tann had aspired to produce a commercial rap
    CD with his lyrics, the statements at issue could be
    viewed as promoting the reputation and stature of the
    conspiracy in the community by spreading the
    conspiracy‘s message of violence and intolerance for
    those who would challenge it. [Citations and alterations
    omitted.]
    We find this line of argument persuasive and supported by case law. In essence,
    one message announced by the coconspirators‘ statements was internal and one was
    external; the internal message furthered the conspiracy by boosting the morale and
    reputation of the coconspirators through the glorification of its activities, while the
    external message reduced the likelihood of interference by outsiders with the
    coconspirators‘ affairs.
    132
    We held in (Brian) Williams v. United States, 
    655 A.2d 310
    , 314 (D.C.
    1995), that if a statement ―can reasonably be interpreted as encouraging [another
    person] to advance the conspiracy or serve to enhance the person‘s usefulness to
    the conspiracy, then the statement is in furtherance of the conspiracy and may be
    admitted.‖ (internal quotation marks omitted); see also 
    Carson, 455 F.3d at 366
    -
    67 (―[I]f the statements can reasonably be interpreted as encouraging a co-
    conspirator or other person to advance the conspiracy, or as enhancing a co-
    conspirator or other person‘s usefulness to the conspiracy, then the statements
    further the conspiracy and are admissible. Such statements include those that . . .
    motivate a co[-]conspirator‘s continued participation.‖) (internal quotation marks
    and citations omitted). Furthermore, numerous courts have held that threats and
    warnings by coconspirators intending to send a message to potential witnesses that
    they would be penalized for cooperating with the government are admissible under
    the coconspirator statement rule. See, e.g., United States v. Westmoreland, 
    312 F.3d 302
    , 309-10 (7th Cir. 2002) (statements admissible because in making them
    the coconspirators intended to preserve the conspiracy by frightening potential
    witnesses). Similarly, we find that the statements (contained in both the internal
    and external message of appellants‘ lyrics) made by the coconspirators and
    introduced into evidence advanced, and were in furtherance of, the conspiracy.
    133
    4. Unfair Prejudice
    Appellants‘ final contention is that the rap lyrics and songs were
    ―substantially more prejudicial than probative‖ because the content was
    particularly shocking and violent. This court has never discussed the prejudicial
    effect of violent rap lyrics, though other courts have. See, e.g., United States v.
    Gamory, 
    635 F.3d 480
    , 493 (11th Cir. 2011) (concluding that the playing of a rap
    video at trial was ―heavily prejudicial‖ because ―[t]he lyrics presented a substantial
    danger of unfair prejudice because they contained violence, profanity, sex,
    promiscuity, and misogyny and could reasonably be understood as promoting a
    violent and unlawful lifestyle‖ while ―not clearly probative of [the defendant‘s]
    guilt‖); State v. Cheeseboro, 
    552 S.E.2d 300
    , 313 (S.C. 2001) (finding that the
    ―minimal probative value‖ of a document containing the defendant‘s rap lyrics was
    ―far outweighed by its unfair prejudicial impact as evidence of appellant‘s bad
    character‖).
    Keeping in mind that ―rap lyrics may employ metaphor, exaggeration, and
    other artistic devices [] and can involve abstract representations of events or
    ubiquitous storylines,‖ (Deyundrea) Holmes v. State, 
    306 P.3d 415
    , 419 (Nev.
    134
    2013) (internal quotation marks and citation omitted), we must consider the
    probative value of the evidence. In other jurisdictions, this question has turned on
    the specificity with which the lyrics describe the facts surrounding the offense(s)
    charged.59 Similarly, we endeavor to determine to what extent the rap lyrics (as
    well as Beaver‘s webpage) should be considered ―autobiographical statements of
    acts relevant to the case.‖ Stuckey, 253 F. App‘x at 483. This is so as to avoid the
    undue risk of the statements ―being misunderstood or misused as criminal
    propensity or bad act evidence.‖ (Deyundrea) 
    Holmes, 306 P.3d at 418
    (internal
    quotation marks omitted).
    59
    Compare 
    id. at 417-20
    (no error where, in the defendant-authored rap
    lyrics at issue, the defendant described ―jack[ing]‖ someone for their necklace in a
    parking lot while wearing a ski mask, and the defendant was accused of accosting
    two men in a parking lot and stealing one man‘s chain necklace while wearing a
    ski mask), and United States v. Stuckey, 253 F. App‘x 468, 482-83 (6th Cir. 2007)
    (unpublished) (no error where the defendant rapped that he ―kills ‗snitches,‘ fills
    their bodies with holes, wraps them in blankets, and dumps them in the road‖ and
    the defendant was accused of shooting a man, wrapping his body in blankets, and
    dumping it in an alley), with 
    Cheeseboro, 552 S.E.2d at 313
    (error where
    references to leaving bodies in a pool of blood without fingerprints were ―too
    vague in context to support the admission‖ of the rap lyrics because the lyrics
    contained ―general references glorifying violence‖ only); see also State v. Hanson,
    
    731 P.2d 1140
    , 1144 n.7 (Wash. Ct. App. 1987) (error where the defendant‘s
    fictional writings were not logically relevant when ―[t]here was no attempt to show
    . . . that [the defendant] wrote about an incident so similar to the crime charged‖).
    135
    Here, the statements were autobiographical in that they discussed the 22nd
    Street Crew and its membership, living by the code required by the gang, selling
    drugs, killing snitches, and killing rivals. Given that appellants‘ conspiracy charge
    was hotly contested by each of them, the probative value of the content of this
    evidence was substantial. Considering also, with regard to the lyrics on the CD,
    that the trial court carefully reviewed each track of the CD to avoid an unfairly
    prejudicial effect (such that 45 minutes of songs were reduced by more than 30
    minutes and some tracks were eliminated in their entirety), we believe that the
    court did not abuse its discretion when it found that the prejudicial effect of the
    evidence did not substantially outweigh its probative value.60 See Legette v. United
    States, 
    69 A.3d 373
    , 388-89 (D.C. 2013). Therefore, we reject appellants‘ claims.
    F. Tann’s Outburst
    Appellants Harris and Arnette appeal the denial of their motions for a
    mistrial based on an ―outburst‖ by appellant Tann following his verdict.
    Approximately two weeks after the beginning of deliberations, the jury returned
    60
    While there is no abuse of discretion on this record, we could easily
    envision a case where lyrics, poetry, or other statements in a form traditionally
    understood to be artistic expression were not sufficiently specific to the charged
    crime so as to have such important probative value. Evidence that doubles as a
    type of art will often be a confusing mixture of truth and fabrication. Therefore,
    trial courts must very carefully scrutinize such materials and statements for unfair
    prejudice.
    136
    full verdicts against appellants Rushing and Beaver. The jury announced its full
    verdict against appellant Cooper the following day. Eight days later, the jury
    returned a partial verdict against Tann, including verdicts on his murder charges.
    At the same time, it announced partial verdicts against the remaining two
    appellants, Harris and Arnette. The jury found Harris and Arnette guilty of
    conspiracy and told the court that deliberations were continuing on their remaining
    counts.
    Once Tann heard that the jury convicted him of the three murders with
    which he was charged, Tann stood up and exclaimed:
    I don‘t see how I can get found guilty, and what type of
    court is this? I wasn‘t even there. . . . [N]owhere near
    . . . . I get found guilty and I‘m innocent. God going to
    challenge y‘all for this. I‘ll see y‘all in heaven. . . . I‘m
    innocent. How the fuck I get found guilty? . . . That‘s
    fucking – that‘s crazy.
    While     Tann    was    making these statements, the court             attempted
    unsuccessfully to call for order. The marshals escorted Tann out of the courtroom
    and into the holding cell. As the judge was dismissing the jurors, he told them that
    they should understand that the courtroom could be an emotional place, and they
    were not to let anything that had just happened impact their remaining
    137
    deliberations. Harris and Arnette immediately moved for a mistrial arguing that
    Tann‘s outburst would prejudice the jury against them, especially since the jury
    had already found Harris and Arnette guilty of a conspiracy rooted in obstruction
    of justice and violence against participants in the legal process. The trial court
    denied their motions.
    The following day, while the jury was in deliberations, the court held a more
    extensive hearing on the facts surrounding Tann‘s outburst. The court indicated
    that it had observed Tann stand up, speak loudly using profanity, and untuck his
    shirt while loosening his tie. Prior to escorting Tann out of the courtroom, one
    marshal pointed his Taser at Tann but did not fire. The court found that Tann‘s
    conduct was not violent or threatening to the jury despite his reference to the
    afterlife. Further, the court observed no reaction from the jury that constituted
    significant concern. Throughout the incident, Arnette and Harris remained seated
    and did not react.
    At the motions hearing, both Harris and Arnette reiterated their concerns
    about prejudice, and Harris requested that the jurors be made available for voir
    dire. Arnette specifically declined to request voir dire. The court denied Harris‘s
    138
    request reasoning that the danger of voir dire was that it might create more
    problems than it solved by triggering safety concerns in the jurors that the court did
    not believe that they had.
    Several days later, the jury returned the remainder of its verdicts involving
    Tann. The jury acquitted him of several charges and convicted him of several
    others.   In subsequent days, the jury returned separate verdicts against Harris and
    Arnette. Unlike Harris, Arnette was acquitted of a number of the charges against
    him.
    In a post-trial motion for a new trial, Harris‘s counsel alleged that she spoke
    with jurors after all of the verdicts had been rendered. According to the motion,
    jurors stated that they believed Tann made a death threat against the jury in the
    course of his outburst and that they otherwise observed Tann consistently threaten
    witnesses throughout the course of the trial. In response, the government noted
    that not all of the jurors remained to speak with the attorneys and not all of those
    that did speak expressed the same view. While a few referred to a ―death threat,‖
    the jurors were not worried – some chuckled when discussing Tann‘s statement
    and ―a number of jurors‖ expressly stated that they were not concerned.
    139
    Furthermore, none of the jurors indicated that they associated Tann‘s statements
    with the other defendants.
    This court reviews the denial of a motion for a mistrial and the trial court‘s
    investigation into jury exposure to unadmitted evidence for an abuse of discretion.
    Ransom v. United States, 
    932 A.2d 510
    , 517 (D.C. 2007); Al-Mahdi v. United
    States, 
    867 A.2d 1011
    , 1018-20 (D.C. 2005). A jury‘s exposure to unadmitted
    evidence implicates a defendant‘s Sixth Amendment right to an impartial jury. See
    Medrano-Quiroz v. United States, 
    705 A.2d 642
    , 649 (D.C. 1997).
    ―Where, as here, the impartiality of [the jury] has been plausibly called into
    question, it is the responsibility of the trial judge to hold a hearing to determine
    whether the allegation of bias has merit.‖ 
    Id. Upon such
    a claim, ―it is the
    government‘s burden to demonstrate that the [jury‘s] contact with extraneous
    information was harmless or non-prejudicial.‖ (David) Hill v. United States, 
    622 A.2d 680
    , 684 (D.C. 1993). ―[T]he evidence of record must justify a high degree
    of confidence that the likelihood of juror partiality has been rebutted.‖ 
    Al-Mahdi, 867 A.2d at 1019
    . Otherwise, ―the court is obliged to declare a mistrial‖ or grant
    other adequate relief. Parker v. United States, 
    757 A.2d 1280
    , 1287 (D.C. 2000).
    140
    Although a hearing is required, ―the extent and type of the trial court‘s
    investigation into the improper contact are confided to the court‘s discretion and
    reviewable only for abuse.‖ Leeper v. United States, 
    579 A.2d 695
    , 699 (D.C.
    1990). There is ―no per se rule that individual questioning of each juror is always
    required,‖ and ―the trial judge has broad discretion to fix the exact procedures by
    balancing the need to make a sufficient inquiry against the concern that the inquiry
    not create prejudicial effects by unduly magnifying the importance of an
    insignificant occurrence.‖ 
    Al-Mahdi, 867 A.2d at 1019
    n.13 (citations and
    alterations omitted).
    Harris and Arnette argue that the jurors might have viewed Tann‘s
    statements as a threat against them and paired that statement with the government‘s
    allegations that the coconspirators had agreed to retaliate against anyone who
    undermined the conspiracy. In doing so, appellants argue that the jury might have
    considered Tann‘s outburst as direct evidence of their guilt of the violent offenses
    (associated with the Terrence Jones-Richard Queen and James Taylor-Bernard
    Mackey incidents) of which they had not yet been convicted. Furthermore, the
    jury may have feared that Harris and Arnette, if acquitted, would carry out Tann‘s
    threat against them.
    141
    Even taking the jury‘s disputed post-trial statements for all they are worth,61
    the trial court did not abuse its discretion in denying the motion for a mistrial
    without questioning the jurors. Tann‘s statements did not expressly implicate his
    codefendants in any way; the trial court gave a prompt curative instruction, even
    taking care to do so sua sponte to avoid the jury linking Tann‘s comments to either
    of his codefendants;62 and the jury did not contact the judge about the outburst or
    register any sort of anxiety, even though it had previously demonstrated its
    willingness to reach out to the court with questions and concerns. Finally, the
    court properly considered the risk that further investigation would turn an
    insignificant matter in the jurors‘ minds into a significant one – a possibility that
    61
    The rule regarding juror‘s post-trial statements is that ―inquiry [is
    allowed] into the existence of conditions or the occurrence of events,‖ but not
    ―inquiry into the thought processes of the jurors.‖ Fortune v. United States, 
    65 A.3d 75
    , 83 (D.C. 2013). Applied to this case, the Fortune rule means that the
    jurors‘ statements may be used to challenge the trial judge‘s determination that
    Tann‘s statements did not constitute a threatening or violent event, but not to show
    the effect Tann‘s statements had on the jury‘s deliberative process.
    62
    Out of the jury‘s presence, the court added that it deliberately gave its
    instruction ―in a way that didn‘t look like it was coming as a request from counsel,
    but from me.‖
    142
    was well within his discretion to take into account.63 
    Al-Mahdi, 867 A.2d at 1019
    n.13.
    In arguing otherwise, appellants rely on several of this court‘s decisions,
    none availing. The cases they cite involved allegations of juror bias that turned on
    facts that the trial court had no way of learning about without questioning the
    jurors. See 
    Al-Mahdi, 867 A.2d at 1021
    (juror contact with third party), 
    Ransom, 932 A.2d at 515-20
    (extraneous information in jury room); 
    Parker, 757 A.2d at 1285-87
    (juror contact with third party); Artisst v. United States, 
    554 A.2d 327
    ,
    330-32 (D.C. 1989) (juror dishonesty in pretrial voir dire about acquaintance with
    defendant). It is crucial here, by contrast, that the trial judge actually observed
    Tann‘s outburst and viewed its effect (or lack thereof) on the jury when
    determining the correct course of action. We find no abuse of discretion in his
    choice.
    63
    Notably, Arnette‘s counsel stated that he agreed with the trial court‘s
    decision to not voir dire the jury for the reasons articulated by the court in its
    ruling.

    A. Evidentiary Issues
    1. Search of Beaver’s Jail Cell
    Approximately one year before trial in this case was about to begin, Cooper
    and Beaver met Freddie Lee Bailey, another prison inmate, while the three were in
    a holding cell. Cooper asked Bailey whether he was housed on the same floor as
    several of the known government cooperators in this case. Cooper further inquired
    whether Bailey would be interested in assaulting the government‘s witnesses in
    various ways. Bailey testified that he refused Cooper‘s solicitation.
    Subsequently, because Beaver was temporarily a government cooperator, he
    was transferred to a part of the jail where other government cooperators, including
    Freddie Lee Bailey, were housed.          Beaver remained there even after his
    cooperation ended and proceedings in this case started.        While this trial was
    ongoing, Beaver sent a letter to Bailey stating that his temporary cooperation was
    merely for purposes of disrupting the government‘s case.        Bailey reported this
    information to prison officials, which resulted in a search of Beaver‘s jail cell and
    the seizure of a second letter from his trash can. The second letter contained
    remarks about Beaver‘s regrets that he had not ―crushed‖ Alphonce Little for being
    144
    a government cooperator. The government admitted portions of both letters at
    trial.
    During a suppression hearing, the details of the search were fleshed out.
    Beaver‘s first letter to Freddie Lee Bailey had been given to a prison official,
    Investigator Alphonso Ashmeade. On December 23, 2008, Ashmeade talked to
    Detective Jeffrey Mayberry, one of the detectives working with the prosecution on
    this case, about the letter and other threats that had been made by Cooper and
    Beaver against Bailey. When the prosecution team arrived to meet Bailey the
    following day, Ashmeade showed Mayberry and others the first letter written by
    Beaver. Ashmeade told Mayberry that he would search Beaver‘s cell for security
    reasons pursuant to his authority as a prison official. Mayberry requested that if a
    prison cell search was to be conducted that any items taken by prison officials from
    Beaver or Cooper‘s cell be held pending application for a warrant. According to
    Mayberry, on the afternoon of December 24, 2008, Ashmeade informed him that
    he conducted a search and took various items from Beaver‘s cell. Mayberry
    reiterated that Ashmeade should hold on to the items pending a warrant. Several
    days later, detectives working with the prosecution team obtained a search warrant
    and ultimately came into possession of the letter that was in Beaver‘s trash can.
    145
    Beaver argued before the trial court, and does so again on appeal, that the
    search by prison officials resulting in the seizure of the second letter about
    ―crushing‖ Alphonce Little was in violation of his Fourth Amendment rights. As a
    factual matter, he contends that the warrantless search occurred not on December
    23rd, but on December 24th, and at the direction of the prosecution. For support,
    Beaver points to inconsistencies between the suppression hearing testimonies of
    Investigator Ashmeade and Detective Mayberry. The primary inconsistency
    involved the date of the search. Ashmeade testified that he conducted the
    ―security‖ search on the 23rd. This timeline did not match up with the testimony
    of Mayberry, who believed that the search occurred on December 24th, after the
    first letter was brought to the attention of the prosecution. Beaver also makes
    much of the fact that Ashmeade stated that he conducted the search for safety
    purposes, but made no effort to remove Freddie Lee Bailey from his cell block
    where he was on the same floor as Beaver and Cooper. Based on these facts,
    Beaver extrapolates that Ashmeade conducted a warrantless evidentiary search
    after meeting with the prosecution team on December 24th and at its direction.
    146
    However, both Detective Mayberry and Investigator Ashmeade testified that
    the search was conducted by prison officials without any prompting by prosecution
    representatives. The trial court found that regardless of the date of the search, and
    any other inconsistencies in the testimony, there was no affirmative evidence to the
    contrary. Moreover, the court found that prison officials had a basis to search the
    cell because they had reason to believe that there was a danger to government
    witnesses then housed in the jail.
    ―Our review of a trial court‘s denial of a motion to suppress is limited.‖
    Joseph v. United States, 
    926 A.2d 1156
    , 1160 (D.C. 2007). ―Our standard of
    review for a trial court‘s ruling on a motion to suppress tangible evidence requires
    that the facts and all reasonable inferences therefrom must be viewed in favor of
    sustaining the trial court‘s ruling.‖ (Robert) Howard v. United States, 
    929 A.2d 839
    , 844 (D.C. 2006) (alteration omitted). ―Essentially, our role is to ensure that
    the trial court had a substantial basis for concluding that no constitutional violation
    occurred.‖ Kaliku v. United States, 
    994 A.2d 765
    , 780 (D.C. 2010) (internal
    quotation marks omitted).
    In Hudson v. Palmer, 
    468 U.S. 517
    , 525-26 (1984), the Supreme Court held
    that prisoners were not protected by the Fourth Amendment against unreasonable
    147
    searches of their prison cells. The Court concluded that ―[t]he recognition of
    privacy rights for prisoners in their individual cells simply cannot be reconciled
    with the concept of incarceration and the needs and objectives of penal
    institutions.‖ 
    Id. at 526.
    Further, the Court determined that ―society would insist
    that the prisoner‘s expectation of privacy always yield to what must be considered
    the paramount interest in institutional security.‖ 
    Id. at 528.
    However, in United
    States v. Cohen, 
    796 F.2d 20
    (2d Cir. 1986), while acknowledging the holding in
    Hudson, the Second Circuit held that in the narrow instance where a prison cell
    search was initiated by the prosecution solely to obtain evidence, a pretrial detainee
    retained a limited Fourth Amendment right to privacy within his cell ―sufficient to
    challenge the investigatory search ordered by the prosecutor.‖ 
    Id. at 24.
    We need not decide whether to adopt Cohen‘s reasoning because we hold
    that the trial court did not abuse its discretion in making the factual finding that the
    search of Beaver‘s jail cell was not conducted at the direction of the prosecution,
    and therefore, was necessarily not a search for purposes of the Fourth Amendment.
    See United States v. Hogan, 
    539 F.3d 916
    , 923-24 (8th Cir. 2008) (―Even if this
    court were to adopt [Cohen], it does not apply here, as the search of [the
    148
    defendant‘s] cell was instigated by jail officials for security reasons and was not
    intended solely to bolster the prosecution‘s case.‖).
    As the trial court correctly noted, regardless of whether the search occurred
    on December 23rd or 24th, the dispositive fact is that both Detective Mayberry and
    Investigator Ashmeade consistently testified that the search was conducted by
    prison officials, without any input or prompt from the prosecution team.
    Ashmeade also explicitly stated that the search was conducted in response to
    legitimate concerns regarding Freddie Lee Bailey‘s safety.
    On appeal, Beaver merely speculates that the inconsistencies between
    Detective Mayberry and Investigator Ashmeade‘s testimony, and the prison‘s
    failure to move Bailey from his cell, proved that the search was conducted at the
    prosecution‘s behest and that Ashmeade sought to cover up his complicity in the
    scheme after the fact. We will not overturn the trial court‘s findings based on such
    conjecture. The trial court was free to credit portions of either witness‘s testimony
    while discounting any inconsistencies. See Bragdon v. United States, 
    668 A.2d 403
    , 406 (D.C. 1995) (per curiam); see also Bose Corp. v. Consumers Union, 
    466 U.S. 485
    , 512 (1984) (―When the testimony of a witness is not believed, the trier of
    149
    fact may simply disregard it. Normally the discredited testimony is not considered
    a sufficient basis for drawing a contrary conclusion.‖). Accordingly, Beaver has
    no Fourth Amendment grounds upon which to challenge the prison search of his
    cell that led to the discovery of the second letter. Thus, the trial court did not err in
    denying his motion to suppress.
    2. Evidence of Uncharged Misconduct, Incarceration, and Fear
    Testimony
    a. Testimony of Andre McDuffie
    Cooper, Tann, Rushing, Harris, and Arnette make claims related to the
    admission of ―other crimes‖ evidence by the government. Prior to trial, the
    government informed the trial court of its intent to put on evidence of criminal
    activity outside the time frame of the charged conspiracy in order to show the
    background to the conspiracy and the associational relationship among appellants
    and their coconspirators. The trial court, after reviewing cases from other
    jurisdictions, particularly United States v. Mathis, 
    216 F.3d 18
    (D.C. Cir. 2000)
    and United States v. Lokey, 
    945 F.2d 825
    (5th Cir. 1991), ruled that it would permit
    the government to elicit this type of evidence. Based on the government‘s
    representations, the court found that there was a relevant purpose to demonstrating
    150
    the joint criminal activities of appellants and others, with minimal risk of
    prejudice.
    The government‘s vehicle for this type of evidence was several ―insider‖
    witnesses, who we have mentioned throughout this opinion, with long-standing ties
    to the 22nd Street Crew. Andre McDuffie was one of these witnesses and the first
    witness called by the government in this case. During his testimony, the
    government asked him whether he knew Rushing. McDuffie said that he did and
    that he was responsible for Rushing‘s training in the 1990s when Rushing was a
    new gang member. Then, McDuffie testified that he taught Rushing a number of
    gang-related skills, including ―how to kill.‖
    Several appellants objected to this ―how to kill‖ testimony at a break in
    Andre McDuffie‘s examination and eventually moved for a mistrial. Appellants‘
    chief objection was that the inference to be drawn from this testimony was that in
    order to ―get in‖ to the 22nd Street Crew, a gang member had to kill or otherwise
    commit serious acts of violence. Therefore, all appellants, who had been labeled
    by the government as 22nd Street Crew members, must have committed killings
    unrelated to the charged murders. The trial court denied appellants‘ motions for
    151
    mistrial.   However, it agreed that the testimony was unfairly prejudicial and
    ordered the testimony stricken.       The judge then gave the following curative
    instruction:
    Mr. McDuffie testified that with regard to Mr. Rushing,
    he said he saw him every day, and then he said he sold
    drugs every day. This was long before this conspiracy
    ever began. And he also said at another point that he
    taught Mr. Rushing how to kill, how to survive. Now,
    I‘m striking that testimony. When I strike testimony, that
    means you are told to disregard it. You can‘t consider it,
    you can‘t think about it as you deliberate in this case.
    And particularly with regard to the testimony about
    allegedly teaching Mr. Rushing to kill, both the
    government and the defense agree that they know of no
    evidence and they have never been aware of any
    evidence that this witness ever taught Mr. Rushing how
    to kill. So, it is extremely important that you strike it.
    There is no known basis for this testimony, and
    consequently you are not to consider it in any way, and
    you are not to discuss it when it comes time to deliberate
    in this case.
    Appellants now appeal the denial of their motions for mistrial.
    ―We review the decision to deny a mistrial motion for abuse of discretion.‖
    (Ronald) Wynn v. United States, 
    80 A.3d 211
    , 219 (D.C. 2013). ―This court will
    not overturn the trial court‘s decision [to deny a mistrial motion] unless it appears
    unreasonable, irrational, or unfair, or unless the situation is so extreme that the
    152
    failure to reverse would result in a miscarriage of justice.‖ Lee v. United States,
    
    562 A.2d 1202
    , 1204 (D.C. 1989) (citation omitted).
    ―In a conspiracy prosecution, the government is usually allowed
    considerable leeway in offering evidence of other offenses ‗to inform the jury of
    the background of the conspiracy charged, to complete the story of the crimes
    charged, and to help explain to the jury how the illegal relationship between the
    participants in the crime developed.‘‖ 
    Mathis, 216 F.3d at 26
    (quoting United
    States v. (Zolton) Williams, 
    205 F.3d 23
    , 33-34 (2d Cir. 2000)). Moreover, ―wide
    latitude is allowed in presenting evidence, and it is within the discretion of the trial
    court to admit evidence which even remotely tends to establish the conspiracy
    charged.‖ 
    Castillo-Campos, 987 A.2d at 493
    .
    Even if the evidence of other crimes is admissible for purposes of
    establishing the conspiracy, ―the next question is whether [its] probative value is
    substantially outweighed by undue prejudice.‖ 
    Lokey, 945 F.2d at 835
    ; United
    States v. Morton, 
    50 A.3d 476
    , 482 (D.C. 2012) (―[E]ven if evidence falls outside
    153
    Drew[64] or within a Drew exception and thus is otherwise admissible, it must be
    excluded if the trial court determines that its probative value is substantially
    outweighed by the danger of unfair prejudice.‖) (internal quotation marks and
    alteration omitted). The trial court, while apparently finding that Andre McDuffie‘s
    testimony may have been relevant to the legitimate prosecutorial goal of
    establishing the associational relationship between the members of the conspiracy,
    found that the probative value of the ―how to kill‖ testimony was substantially
    outweighed by the danger of unfair prejudice.65        ―[W]e owe a great deal of
    deference‖ to the trial court on such a finding. 
    Jenkins, 80 A.3d at 999
    .
    64
    Drew v. United States, 
    331 F.2d 85
    (D.C. Cir. 1964) (holding that
    evidence of other crimes is inadmissible to prove a defendant‘s disposition to
    commit the crime charged but may be admissible for other legitimate non-
    disposition purposes).
    65
    We note that the prejudice to appellants seems to have been fairly
    significantly lessened by the context of Andre McDuffie‘s testimony. First,
    McDuffie testified that he ―taught‖ Rushing to kill – not that he participated in
    joint killings with Rushing or was aware of any evidence that Rushing practiced
    this part of McDuffie‘s teachings. Second, the strongest inference to be drawn
    from McDuffie‘s testimony was that when the ―little locs‖ were taught the skills of
    gang membership, it was the older members only that performed acts of violence.
    According to McDuffie, the ―little locs‖ appear to have learned by observation: ―If
    we had to go make a move on somebody, so far as [to] inflict the act of violence,
    we would take [the little locs] with us and let them see how we do it.‖
    154
    We owe equally great deference to the trial court when reviewing its
    selection of a remedial measure responsive to such problematic testimony. See
    United States v. McLendon, 
    378 F.3d 1109
    , 1113 (D.C. Cir. 2004) (―[W]e should
    not lose sight of the fact that the same judge who initially weighed the [Fed. R.
    Evid. 403] balance against admission of the evidence, subsequently determined
    that the [evidence] did not warrant a mistrial.‖). ―A mistrial is a severe remedy – a
    step to be avoided whenever possible, and one to be taken only in circumstances
    manifesting a necessity therefor.‖ Najafi v. United States, 
    886 A.2d 103
    , 107
    (D.C. 2005); see also (Richard) Clark v. United States, 
    639 A.2d 76
    , 78 (D.C.
    1993) (―Assuming, for the sake of argument, that [the evidence] constituted ‗other
    crimes‘ evidence, we conclude that [it] did not result in prejudice so great as to
    render the trial court‘s refusal to grant a mistrial an abuse of discretion.‖).
    Here, the offending testimony was a very brief reference at the outset of an
    extremely lengthy trial. Cf. Veney v. United States, 
    936 A.2d 811
    , 828-29 (D.C.
    2007) (other crimes evidence harmless, in part, because objectionable testimony
    heard on the first day of a three-day trial). The reference was not repeated by the
    government, or its witnesses, and not argued in closing. And the trial court gave a
    very strong, and almost immediate, curative instruction stating that there was ―no
    155
    evidence‖ that Andre McDuffie had taught Rushing to kill. See 
    McLendon, 378 F.3d at 1114
    (no abuse of discretion in denying a motion for mistrial based on
    exposure of jury to evidence determined to violate Fed. R. Evid. 403 because of
    ―the brevity of the offending testimony and the clarity of the district court‘s
    [curative] instructions‖). Therefore, we find that the trial court did not abuse its
    discretion in denying the motions for mistrial.
    b. Testimony of Darryl Travers
    Rushing makes a separate ―other crimes‖ argument based on the testimony
    of another government witness, Darryl Travers. During direct-examination,
    Travers made reference to statements that Rushing had made to him about being
    housed in the same section of the jail as 22nd Street Crew member Stephen Gray.
    On cross-examination, various defendants brought out the fact that Travers himself
    had been released from prison in order to assist the government with its
    investigation. In response to this bias cross-examination, on re-direct, the
    government elicited from Travers that if he remained in prison he would have had
    safety concerns as a government cooperator. Appellants objected and moved for a
    mistrial on the grounds that the inference was that if Travers remained in jail, he
    would be harmed by one of the appellants. The trial court declined to order a
    156
    mistrial, but it sustained the objection and instructed the jury that there was no
    evidence that Travers would have any safety concerns had he remained in jail.
    We find no abuse of discretion based on the trial judge‘s treatment of Darryl
    Travers‘ testimony.      As to Travers‘ reference to the fact of Rushing‘s
    incarceration, there was minimal prejudice to Rushing because many of his jail
    calls were played for the jury, at which time the jurors inevitably became aware
    that Rushing was incarcerated during the period leading up to the trial. Moreover,
    neither Travers‘ testimony, nor any other evidence, linked Rushing‘s incarceration
    with any of the offenses of which he was charged in this case, particularly the
    murder of Laquanda Johnson and assault of Keisha Frost, which was the central
    event in the government‘s case against Rushing. (David) Washington v. United
    States, 
    760 A.2d 187
    , 196 (D.C. 2000) (prejudicial effect limited where ―there was
    no evidence as to what crime may have resulted in appellant‘s supposed
    incarceration‖ as opposed to ―the situation where the crime charged and the prior
    arrest involve the same offense‖) (internal quotation marks omitted). And the
    testimony about Travers‘ fear of remaining in prison, even if improper, did not
    require the trial court to grant the motion for a mistrial. The testimony was a brief
    reference in a very lengthy trial and was fully mitigated by the trial court‘s curative
    157
    instruction. Consequently, we grant Rushing no relief on the basis of these claims.
    See Chase v. United States, 
    656 A.2d 1151
    , 1155 n.8 (D.C. 1995) (no abuse of
    discretion by trial court in denying motion for mistrial where government
    attempted to elicit ―fear‖ testimony because denial of motion was not
    ―unreasonable, irrational or unfair‖).
    3. Evidentiary Rulings During Cooper’s Case-in-Chief
    Cooper argues that the trial court‘s various erroneous evidentiary rulings
    collectively deprived him of the right to present a complete defense. See Heath v.
    United States, 
    26 A.3d 266
    , 280-81 (D.C. 2011) (―[W]hether an erroneous
    exclusion of defense evidence violates the defendant‘s constitutional right to
    present a defense depends upon whether there exists a reasonable probability that
    the omitted evidence . . . would have led the jury to entertain a reasonable doubt
    that did not otherwise exist.‖) (emphasis omitted). After examining his claims, we
    reject his argument.
    a. Statements by Tamika Bradshaw
    Cooper argues that the trial court erred when it prevented him, during his
    testimony, from repeating a statement made to him by a woman named Tamika
    Bradshaw. Cooper denied murdering Terrence Jones and testified that he first
    learned about the Terrence Jones shooting from ―[t]his girl name[d] Tamika.‖
    158
    Cooper‘s defense counsel then asked Cooper what Bradshaw had said to him.
    The government objected to the admissibility of Bradshaw‘s exact statement
    (although it did not specify the grounds). The trial court called the parties to the
    bench, and Cooper‘s defense counsel stated that Bradshaw‘s statement was not
    hearsay because it was offered to show Cooper‘s state of mind and relevant
    because ―it‘s how [Cooper] found out about the shooting.‖     Without explanation,
    the trial court sustained the objection.      Cooper‘s defense counsel then asked
    Cooper where he was when he ―became aware that there had been a shooting.‖
    Cooper replied that he was ―[in] the parking lot . . . [a]cross from the basketball
    court‖ on 22nd Street.
    Assuming that the trial court should have allowed Cooper to testify as to
    Bradshaw‘s statement under the state-of-mind exception to the rule against
    hearsay, her precise statement was of very minimal importance, and there was no
    harm because Cooper was able to present the substance of what Bradshaw
    conveyed to him. See United States v. Terry, 
    702 F.2d 299
    , 314 (2d Cir. 1983)
    (error in suppressing evidence harmless where its essence was nonetheless
    conveyed to the jury by defense counsel).
    159
    b. Statements by Laquanda Johnson
    Cooper also claims that the court erred in not admitting statements for the
    truth of the matter allegedly made by Laquanda Johnson to him in the course of a
    conversation between Cooper and Laquanda following the Terrence Jones
    shooting. The statements were, in effect, that she knew that Cooper was not
    involved in the shooting because she had seen him in a parking lot on 22nd Street
    at the time.
    Cooper argued to the trial court that because the government had elicited
    certain statements by Laquanda Johnson to his disadvantage under a forfeiture-by-
    wrongdoing theory, Laquanda‘s statements favorable to him should also be
    admitted. The government registered a hearsay objection. The trial court agreed
    with the government that the forfeiture-by-wrongdoing exception to the hearsay
    rule was not designed to advantage the wrongdoer; therefore, the statements were
    not admissible for their truth and the court instructed the jury that they were
    admissible for state-of-mind purposes only. The court again limited the
    admissibility of Laquanda‘s statements to their effect on Cooper‘s state of mind
    when Cooper sought to repeat her statements in the context of explaining that
    160
    another individual, Patrick Williams, overheard the same conversation between
    Laquanda and Cooper after the Terrence Jones murder.
    The trial court did not err in its treatment of this testimony. In Sweet v.
    United States, 
    756 A.2d 366
    , 379 (D.C. 2000), we held that ―it is only the party
    who wrongfully procures a witness‘ absence who waives the right to object to the
    adverse party‘s introduction of the witness‘ prior out-of-court statements.‖ 
    Id. (alterations omitted)
    (quoting United States v. Houlihan, 
    92 F.3d 1271
    , 1283 (1st
    Cir. 1996)).   We also explicitly stated that the forfeiture-by-wrongdoing rule
    ―which provides for the waiver of objection by the party who causes the witness
    absence cannot logically strip the government of its hearsay objections.‖ 
    Sweet, 756 A.2d at 379
    (internal quotation marks omitted).
    c. Statements by Cooper to Brandon Elzie
    Finally, Cooper claims that the court erred by excluding his statement to a
    prison guard, Brandon Elzie. Cooper attempted to elicit from Elzie the fact that he
    had told Elzie that he could not be in the same part of the jail as Freddie Lee Bailey
    because Bailey was a cooperating witness, and therefore Elzie should escort him to
    another part of the jail. This testimony was offered by Cooper to show that
    161
    Bailey‘s testimony, which was that Cooper made inculpatory statements to him
    while they were together in a holding cell, was untrue.
    The government raised a hearsay objection, arguing that Cooper‘s ―self-
    serving‖ statement was being offered for the truth of fact that Cooper was not
    permitted to be in the presence of a government witness. Attempting to negotiate
    an acceptable middle ground, the trial court asked Cooper‘s defense counsel if he
    would be amenable to asking Elzie if Cooper informed him of ―something‖ that
    caused Elzie to take Cooper away from Bailey.             Although Cooper‘s defense
    counsel stated that he ―just [didn‘t] think any of it[] [is] hearsay,‖ he agreed to ask
    the question in the way proposed by the trial court.
    Cooper‘s defense counsel then asked Elzie what he did ―based upon the
    information that Mr. Cooper gave you.‖ Elzie replied, ―In turn, I then escorted Mr.
    Cooper back upstairs.‖       Assuming arguendo that the trial court should have
    admitted the contents of Cooper‘s statements to Elzie to show Cooper‘s state of
    mind, any error was harmless. The trial judge‘s handling of Elzie‘s testimony
    allowed Cooper to rebut the substance of Bailey‘s statements, which was Cooper‘s
    purpose in calling Elzie to the stand. 
    Terry, 702 F.2d at 314
    .
    162
    In sum, even assuming error in two of these evidentiary rulings, there was no
    violation of Cooper‘s constitutional right to present a complete defense. Any
    prejudice to Cooper was very minimal because he was permitted to elicit evidence
    that put the defense theories before the jury. See (Maurice) Morris v. United
    States, 
    622 A.2d 1116
    , 1128-29 (D.C. 1993) (―even if the judge erred, the defense
    suffered little, if any prejudice‖ because appellant‘s case was ―clearly before the
    jury‖ and the excluded testimony ―would not have bolstered appellant‘s case‖).
    Therefore, we reject Cooper‘s claim based on these evidentiary rulings.
    4. Admission of Tann’s Videotaped Statement
    During the prosecution‘s rebuttal case, the government played a portion of
    Tann‘s videotaped statement to the police on matters relevant to the Leslie Jones
    murder. In the videotaped statement, Tann made references to visiting Darryl
    Travers on the evening of the murder, which conflicted with the testimony of
    several of Tann‘s alibi witnesses who had testified that Tann was with them that
    evening.
    The tape did not make reference to any appellant other than Tann. Nor was
    any appellant other than Tann charged with the Leslie Jones murder (although his
    murder was listed as an overt act on the conspiracy charge). Cooper, the only
    163
    appellant convicted under a vicarious liability theory – for the Laquanda Johnson
    murder only – now raises a claim pursuant to Akins v. United States, 
    679 A.2d 1017
    (D.C. 1996) based on the admission of the videotape.
    ―[I]n a joint conspiracy trial where the government relies on a theory of
    vicarious liability, statements may not be introduced under the statements of [a]
    party opponent exception to the rule against hearsay . . . unless they are admissible
    as coconspirators‘ statements in furtherance of the conspiracy . . . .‖ 
    Id. at 1031.
    However, Cooper was not prosecuted under a vicarious liability theory for the
    conspiracy count of which the murder of Leslie Jones was an overt act. Instead,
    Cooper was tried as a principal in the conspiracy.       Because Tann‘s statement
    impacted Cooper on the overt act of the conspiracy charge only, a charge for which
    he was not prosecuted under a theory of vicarious liability, Akins is inapplicable
    and Cooper‘s claim is meritless.
    B. Instructional Issues
    1. Obstruction of Justice Instruction
    Appellants Beaver, Cooper, and Tann were charged with obstruction of
    justice under D.C. Code § 22-722 (a)(2)(A) and (a)(6). Appellants challenge the
    164
    trial court‘s obstruction of justice jury instruction and allege that it amounted to a
    constructive amendment of the indictment.
    The relevant counts, as listed in the indictment, were as follows:
    Between on or about April 17, 2004, and on or about
    April 30, 2004 . . . Cooper . . . corruptly persuaded, and
    endeavored to cause or induce, Laquanda Johnson, the
    sister of a witness in an official proceeding, to wit, the
    investigation into the April 17, 2004 murder of Terrence
    Jones and assault of Richard Queen . . . with the intent to
    influence, delay and prevent the truthful testimony of
    Kyara Johnson in that proceeding . . . in violation of
    [D.C. Code § 22-722 (a)(2)(A) and (a)(6) (2012 Repl.)].
    Between on or about April 30, 2004, and on or about July
    11, 2006 . . . Cooper . . . Tann . . . Beaver . . . Gilliam . . .
    and other persons . . . corruptly persuaded, and
    endeavored to cause or induce, Laquanda Johnson, with
    the intent to persuade her to influence, delay, and prevent
    the truthful testimony of her sister, Kyara Johnson, a
    witness in an official proceeding, to wit, United States v.
    Lannell Cooper . . . in violation of [D.C. Code § 22-722
    (a)(2)(A) and (a)(6) (2012 Repl.)].[66]
    Between on or about June 1, 2006, and on or about July
    11, 2006 . . . Tann . . . corruptly persuaded and by
    threatening letter and communication, endeavored to
    influence, intimidate and impede Donnise Harris, a
    witness in an official proceeding, to wit, the case of
    United States v. Saquawn Harris . . . with the intent to
    66
    See Section VII (D) supra. Count 25 has been included here again for
    clarity.
    165
    influence, delay, and prevent the truthful testimony of
    Donnise Harris in that proceeding . . . in violation of
    [D.C. Code § 22-722 (a)(2)(A) and (a)(6) (2012 Repl.)].
    Prior to final jury instructions, the government requested that the trial court
    use the pattern jury instruction for the ―catch-all‖ version of obstruction of justice
    under D.C. Code § 22-722 (a)(6) for Counts 24 and 25 involving the Johnson
    sisters. Criminal Jury Instructions for the District of Columbia, No. 6.101F (5th
    ed. rev. 2013). Appellants did not object, and the court agreed to do so. When the
    instructions on the elements of Count 24 were given, the court instructed the jury,
    in relevant part, as follows:
    [T]he essential elements of obstructing justice under this
    count . . . are, first, that the defendant corruptly, or by
    means of force, obstructed or impeded or endeavored to
    obstruct or impede the due administration of justice and
    any official proceeding in the Superior Court of the
    District of Columbia. [Emphasis added]
    The trial court instructed the jury in accordance with the D.C. Code § 22-722
    (a)(6) pattern instruction, except that the court inadvertently changed the phrase
    ―threats of force‖ to ―means of force‖ when describing one potential manner in
    which appellants could have obstructed justice. The trial court did so for each
    obstruction of justice count, including Tann‘s Count 41 which described Donnise
    Harris as the victim. These instructions went without objection. The court also
    166
    issued written instructions to the jury; however, the written instructions did not
    contain the ―means of force‖ language. Instead, the written instructions used the
    phrase ―threats of force‖ as authorized by the pattern jury instruction for § 22-722
    (a)(6).
    After the verdicts, but prior to sentencing, Cooper filed a motion for a new
    trial alleging that the flawed instruction amounted to a constructive amendment of
    the indictment. Cooper‘s argument was that by instructing the jury that it could
    convict if it found that obstruction of justice had been committed by a ―means of
    force,‖ the court permitted the jury to consider a theory of liability on which
    appellants were not indicted. Further, Cooper and other appellants pointed to
    evidence at trial that went toward a ―force‖ theory of obstruction of justice, as
    opposed to the ―persuasion‖ theory of obstruction of justice that was explicitly
    charged in the language of the indictment, thereby enhancing the likelihood of
    prejudice as a result of the instruction. After a post-trial hearing, the trial court
    denied appellants‘ motions.
    Our first task is to determine the correct standard of review of this issue on
    appeal.      ―[P]lain error review applies to a claim that an indictment has been
    167
    constructively amended if an objection has not been made at trial level.‖
    (Alexander) Smith v. United States, 
    801 A.2d 958
    , 962 (D.C. 2002). Despite this
    principle, appellants allege that their claims should not be subject to plain error
    review because (1) they were ―essentially preserved in the trial court . . . by
    appellants‘ post-verdict motions for a new trial‖; (2) the government invited the
    error; (3) appellants ―reasonably relied on the judge‘s [written] jury instructions
    which did not include [the means of force] phrase‖; and (4) ―there is a strong
    likelihood that appellants did not actually hear the precise words uttered by the
    judge.‖
    Appellants‘ arguments about the standard of review are unpersuasive. Their
    argument that the claim was ―essentially preserved‖ by way of the post-conviction
    motions for a new trial must fail because such post-trial motions do not amount to
    a ―timely objection,‖ and thus, will not save an appellant from plain error review.
    See (Tristan) Smith v. United States, 
    847 A.2d 1159
    , 1160 (D.C. 2004) (per
    curiam) (superseded by statute on other grounds); United States v. (Chevalier)
    Thompson, 
    27 F.3d 671
    , 673 (D.C. Cir. 1994) (―[A] post-verdict motion for a new
    trial is not the same as a timely objection: the delay eliminates any chance that the
    judge could correct the error without a duplicative trial, and according review as if
    168
    a timely objection had been raised virtually invites strategic behavior by defense
    counsel.‖). Furthermore, there is no authority for appellants‘ remaining arguments.
    The ―point of the plain-error rule‖ is to oblige the defendant to advise the judge
    when a mistake occurs; therefore, the rule ―requires defense counsel to be on his
    toes, not just the judge . . . .‖ United States v. Vonn, 
    535 U.S. 55
    , 73 (2002); see
    also Davis v. United States, 
    984 A.2d 1255
    , 1259 (D.C. 2009). Consequently, we
    review for a constructive amendment using the plain error standard.
    The Fifth Amendment prohibits any person from being ―held to answer for a
    capital, or otherwise infamous crime, unless on a presentment or indictment of a
    Grand Jury . . . .‖ U.S. CONST amend. V. ―[W]here a trial court broadens the
    possible grounds for conviction by adding another factual basis to those contained
    within the indictment, the court constructively – and impermissibly – amends the
    indictment.‖ Wooley v. United States, 
    697 A.2d 777
    , 781 (D.C. 1997). Only a
    grand jury may ―broaden‖ the charges in an indictment. Stirone v. United States,
    
    361 U.S. 212
    , 215-16 (1960).
    Here, there were essentially two possible constructive amendments that
    could have occurred: (1) by the addition of the phrase ―threats of force‖ in the
    169
    written instructions and (2) by the addition of the phrase ―means of force‖ in the
    oral instructions. Neither phrase was included in the language of the indictment.
    However, addressing each issue in turn, we find that appellants are owed no relief
    based on the inclusion of either phrase in the jury instructions under the plain error
    standard.
    A claim of plain error based on the addition of the phrase ―threats of force‖
    is foreclosed by our case law that holds an appellant cannot satisfy the fourth prong
    of plain error when the indictment at issue includes a citation to a criminal statute
    from which a trial court recites when instructing a jury, even if the language of the
    indictment does not otherwise track the wording of the cited offense. Bolanos v.
    United States, 
    938 A.2d 672
    , 687 (D.C. 2007); (Alexander) 
    Smith, 801 A.2d at 961-62
    .     In Bolanos, one of several defendants was charged with aggravated
    assault while armed (―AAWA‖) by an indictment that alleged the offense was
    committed by ―knowingly or purposely caus[ing] serious bodily injury‖ to the
    
    victim. 938 A.2d at 686
    . However, the Bolanos jury instructions included an
    alternative mens rea, proper under another subsection of the AAWA statute but not
    explicitly alleged in the indictment, ―that is, the defendant manifested extreme
    indifference to human life by knowingly engaging in conduct which created a
    170
    grave risk of serious bodily injury.‖ 
    Id. In rejecting
    appellant‘s claim of plain
    error based on a constructive amendment, we held:
    While the indictment failed to state both subsections of
    the aggravated assault statute, it did include a citation
    that encompassed both subsections; thus, [appellant] had
    notice he would be required to defend against both
    prongs. We find that [appellant] has failed to show that a
    miscarriage of justice occurred, in light of the notice he
    received through the citation to the aggravated assault
    statute included in the indictment.[67]
    Here, while the phrase ―threats of force‖ found in the written jury
    instructions was not used in the indictment, the indictment did cite to D.C. Code
    § 22-722 (a)(6), which includes this phrase in describing the offense of obstruction
    of justice. Therefore, under our precedent, appellants cannot prevail on the basis
    of the inclusion of the phrase ―threats of force‖ in the written instructions.
    67
    
    Id. at 687.
    We came to the same conclusion in (Alexander) Smith where
    the trial court‘s jury instruction added a second means of committing aggravated
    assault that was not explicitly charged in the language of the indictment. There,
    we held ―even if we assume that the evidence and instruction plainly amended the
    language of the indictment, there is no risk that the fairness, integrity or public
    reputation of judicial proceedings will be affected where the indictment included a
    citation that encompassed both subsections of the aggravated assault statute, and
    the evidence amply supported appellant‘s conviction of aggravated 
    assault.‖ 801 A.2d at 960-62
    .
    171
    Appellants‘ argument based on the ―means of force‖ language mistakenly
    read by the trial court during its oral jury instructions also falls short; this time the
    claim fails on the third prong of the plain error standard, which requires that
    appellants ―demonstrate that the error affected [their] substantial rights by showing
    a reasonable probability that it had a prejudicial effect on the outcome of [their]
    trial[s].‖ Comford v. United States, 
    947 A.2d 1181
    , 1189 (D.C. 2008). First, the
    written instructions did not include the language ―means of force.‖ See generally
    People v. Wilson, 
    187 P.3d 1041
    , 1069-70 (Cal. 2008) (―To the extent a
    discrepancy exists between the written and oral version of jury instructions, the
    written instructions provided to the jury will control.‖). Although the trial court
    did not instruct the jury that the written instructions controlled in the event of a
    conflict with its oral instructions, it is doubtful in this case that the phrase ―means
    of force‖ had a meaningful influence upon the jury‘s verdict. The trial court‘s
    words were uttered near the end of month seven of a nine-month trial and during
    an instructional period that lasted the better part of two court sessions and involved
    forty-nine counts relating to six defendants. A much more reasonable scenario is
    that the jurors relied upon the written instructions, which used the ―threats of
    force‖ language, during their extensive deliberations.
    172
    Second, the government did not argue for appellant‘s guilt based on a
    68
    ―means of force‖ theory of liability.        See Portillo v. United States, 
    62 A.3d 1243
    ,
    1260 (D.C. 2013) (no plain error where, in a burglary case, the government argued
    an entry-with-intent-to-steal theory of liability as charged, as opposed to the
    additional entry-with-intent-to-assault theory added by trial court in jury
    instructions). Finally, appellants have not identified ―any deficiency in the defense
    strategy at trial due to the discrepancy between the indictment and the jury
    instructions relating to the [obstruction of justice] charge[s].‖ 
    Id. Therefore, appellants
    fail to meet their burden on the third prong of plain error review and we
    reject their claims.69
    68
    When referring to the evidence on Counts 24, 25, and 41, the government
    recounted testimony that Tann asked Donnise Harris to testify favorably for
    appellant Harris; that Cooper approached Laquanda Johnson and offered her a
    bribe of drugs and money to influence Kyara Johnson‘s testimony; and that Dewey
    Chappell was working with Beaver, Tann, and Brian Gilliam to find the sisters to
    ―change their testimony.‖ While the government‘s argument described how some
    of this testimony explained efforts by the coconspirators involved the threats of
    force and contemplated the use or means of force the government‘s argument did
    not contend that any of acts underlying these obstruction of justice counts were
    executed by such a means or use of force.
    69
    We also note that Counts 24, 25, and 41 cited to D.C. Code § 22-722
    (a)(2)(A), which makes unlawful the knowing use of ―physical force‖ to
    ―influence, delay, or prevent the truthful testimony of [a] person in an official
    proceeding . . . .‖ This means that even if appellants‘ ―means of force‖ claims
    survived the third prong of plain error review, our decisions in Bolanos and
    (continued…)
    173
    2. Lesser-Included Offense Instruction:           Relationship Between
    Felony and Second-Degree Murder
    Appellants Tann and Arnette were charged with one count of first-degree
    premeditated murder while armed and two counts of first-degree felony murder
    related to the death of Terrence Jones. The two underlying felonies alleged were
    the attempted robbery of Terrence Jones and the completed robbery of Richard
    Queen. At the MJOA stage, the government agreed that there was insufficient
    evidence on the first-degree premeditation element of the premeditated murder
    count for both appellants. The court ruled that the count would be reduced to the
    lesser-included offense of second-degree murder while armed of Terrence Jones.
    Therefore, for the Terrence Jones murder, the jury was charged with rendering
    verdicts on (1) one second-degree murder count for both appellants and (2) two
    first-degree felony murder charges for each.
    During final jury instructions, the trial court instructed the jury that it could
    find both appellants guilty of the lesser-included offense of second-degree murder
    (…continued)
    (Alexander) Smith would require us to deny them relief because they could not
    ―show that a miscarriage of justice occurred, in light of the notice [they] received
    through the citation to [the obstruction of justice] statute included in the
    indictment,‖ which put them on ―notice that [they] would be required to defend
    against‖ a use-of-physical-force theory. 
    Bolanos, 938 A.2d at 687
    .
    174
    while armed, even if it found reasonable doubt as to the first-degree felony murder
    charges. Ultimately, the jury found Tann and Arnette each guilty of three counts
    of second-degree murder while armed: the second-degree murder charge that had
    been reduced from first-degree premeditated murder and two counts of second-
    degree murder as lesser-included offenses of the first-degree felony murder
    charges.
    Appellants now argue that the jury was improperly instructed. They contend
    that second-degree murder is not a lesser-included offense of first-degree felony
    murder under the ―elements‖ test in Blockburger v. United States, 
    284 U.S. 299
    (1932) and Byrd v. United States, 
    598 A.2d 386
    (D.C. 1991). Their claim is that
    second-degree murder requires the element of ―malice aforethought‖ – an element
    not contained in the offense of first-degree felony murder. However, appellants‘
    argument is foreclosed by our decisions that hold second-degree murder is, in fact,
    a lesser-included offense of first-degree felony murder. See Towles v. United
    States, 
    521 A.2d 651
    , 656-58 (D.C. 1987) (en banc).        Therefore, their claims
    afford them no basis for relief.
    175
    3. Attitude and Conduct Instruction
    During final instructions, the court issued the jury an ―attitude and conduct‖
    instruction. No appellant objected. Tann, Arnette, and Harris now argue that this
    instruction was fundamentally similar to the instruction deemed flawed in Jones v.
    United States, 
    946 A.2d 970
    (D.C. 2008), for unduly favoring a collective result
    over the individual opinions of the jurors. We find no plain error in the instruction.
    Appellants are correct that the instruction contained an element found
    problematic in Jones: a statement that the ―final test‖ of the jurors‘ service turned
    on their verdicts, not their earlier opinions. However, the instruction did not
    contain the ―purposive‖ language that we have identified as underlying the Jones
    holding. See Lampkins v. United States, 
    973 A.2d 171
    , 173 (D.C. 2009) (flaw in
    Jones was informing the jury that its ―purpose should not be to support your own
    opinion, but rather to ascertain and to declare the truth‖); see also Grant v. United
    States, 
    85 A.3d 90
    , 99-100 (D.C. 2014) (error was in telling the Grant jury that its
    purpose was to reach a verdict thereby expressing to the jurors that consensus was
    preferred to genuine agreement).
    176
    Additionally, the instant instruction also (1) included language praised in
    McClary v. United States, 
    3 A.3d 346
    , 355 (D.C. 2010), explaining the purpose of
    jurors not pre-announcing opinions, and (2) contained wording similar to that
    approved by Jones, reminding jurors not to surrender their honestly held opinions
    and informing them that it was their duty to reach verdicts only if they could
    conscientiously do 
    so. 946 A.2d at 974
    . Accordingly, we cannot say that it should
    have been clear or obvious to the trial court that there was error in the instruction.
    In any event, appellants cannot meet prong three of the plain error test because the
    jury clearly engaged in extensive and discerning deliberations before returning
    verdicts. 
    Id. at 976
    (lengthy deliberations informed the court‘s determination that
    Jones could not show a ―reasonable probability‖ that the erroneous instruction
    changed the verdict).
    C. Closing and Rebuttal Argument
    All appellants argue that the cumulative impact of several allegedly
    improper remarks made by the government during its closing and rebuttal
    arguments requires reversal. We disagree and decline to grant appellants relief.
    1. Government’s Closing Argument
    Near the beginning of its closing argument, the government attempted to
    explain why culpability for the Laquanda Johnson murder extended beyond
    177
    Alphonce Little, the 22nd Street Crew member who shot her and Keisha Frost.
    The government made several statements to the effect that the government had a
    responsibility not to ―turn [its] back[]‖ on the community and ignore the larger
    criminal problem on 22nd Street. In the course of this explanation, the government
    briefly transitioned from ―we‖ statements to a single ―you‖ statement directed at
    the jury when it stated, ―[We are] asking you, at this point, to do what the
    community requires.‖70     Several appellants objected and the court sustained their
    70
    The prosecutor‘s argument was:
    This is not a situation that you can just sum up in
    three lines. It‘s not, Laquanda Johnson was killed;
    Alphonce Little was arrested; Alphonce Little pled
    guilty.
    There‘s much, much more to what happened on
    [the night of Laquanda Johnson‘s murder].
    Now, the defendants behind me would very much
    like that you stop right there. And it would have been
    easy to just call it case closed. . . .
    But to do so would have required that we turn a
    blind eye to what had been happening there for years.
    We would have had to turn our backs on that community.
    We would have had to turn our backs on that entire two-
    block area. We would have had to ignore the other
    victims.
    (continued…)
    178
    objections. After returning from a break in the government‘s argument, the court
    instructed the jurors that they did not represent the community and, in essence, that
    they were not to follow that line of the government‘s argument
    At the very end of its closing argument, the government referenced the
    testimony of one of its witnesses, Tyrone Curry. Under cross-examination about
    his reasons for cooperation with the government, Curry said that his sister had been
    killed six months earlier in the area around 22nd Street and that he had come to the
    conclusion that ―[E]nough is enough. How many people got to die before you say
    something?‖ The government referred the jury back to Curry‘s testimony as it
    concluded its closing argument and then used Curry‘s quote to argue: ―Ladies and
    gentlemen, enough is enough. You need to hold these men accountable for what
    they‘ve done.‖71
    (…continued)
    And we’re asking you, at this point, to do what that
    community requires. We owed it to that community to
    investigate this thoroughly. [Emphasis added].
    71
    The full argument was as follows:
    Like I said, [it] didn‘t start on July 11[;] it didn‘t
    end on July 11. The evidence has shown you the men
    behind me have caused too much pain and suffering to
    (continued…)
    179
    2. Government’s Rebuttal Argument
    During his closing argument, Cooper made the case that what the
    government‘s evidence had shown was not a criminal conspiracy defined by
    specific time periods and goals, but merely an ongoing participation in a
    community attitude that embraced a drug culture and black market. Furthermore,
    Cooper argued that the government was biased against him and had allowed
    emotion and preconceived notions about the appellants‘ guilt to bias itself in favor
    of certain witnesses in the case. In Harris‘s closing, he asserted that some of the
    government‘s witnesses were motivated to lie by the prospect of relocation
    assistance and money from the government. He further noted that some witnesses
    had received thousands of dollars from the government
    (…continued)
    22nd Street. . . . And it makes me think back to the one
    thing Tyrone Curry said. He said it on the stand, and I
    want to make sure I get it right because he said it better
    than I could have. He was being cross-examined about
    why it was that he finally came forward, and he said,
    ―My sister was killed six months ago, and I came to the
    conclusion that enough is enough. How many people
    gotta die before you say something?
    Ladies and gentlemen, enough is enough. You
    need to hold these men accountable for what they’ve
    done. [Emphasis added].
    180
    The government responded in rebuttal that the law of conspiracy was
    designed in such a way that showing concrete time periods and single objectives
    was not required. The government further remarked that if the law was set up
    differently, then prosecuting criminal organizations such as the ―Italian Mafia‖
    would be too difficult.72   The trial court overruled immediate objections and ruled
    against later motions for a mistrial. However, it instructed the jury that the ―mafia‖
    comment was ―unfortunate.‖ The trial court further told the jury that it should not
    be thinking about any particular historical group when weighing the evidence in
    this case, particularly groups with traditionally negative connotations.
    Later in rebuttal argument, the government returned to the explanation of its
    charging strategy, telling the jury the purpose behind its expansive prosecution of
    the 22nd Street Crew was because it had ―an obligation not to just look at what is
    72
    With regard to the ―Italian Mafia,‖ the prosecutor stated:
    There‘s no requirement [in the law of conspiracy]
    that says it has to be a limited period of time. . . . There‘s
    no requirement that it has to be just one objective . . . .
    There‘s no requirement that it can only be about one
    [l]ittle incident. And think about it[;] it makes perfect
    sense. If that were the only thing the conspiracy law
    could prosecute, it‘d never prosecute gangs[;] it‘d never
    prosecute organized crimes. All those Italian Mafia
    families, they’d never get prosecuted. [Emphasis added].
    181
    right before us, but to dig deeper. It‘s just like a weed in the sidewalk, right? You
    can pluck off that yellow top, and a Dandelion is coming back.‖73
    Finally, when concluding rebuttal, the government responded to the
    argument that it was biased against appellants and in favor of certain government
    witnesses.    Attempting to exploit the use of the term ―bias,‖ the government
    explained that it had no ―bias‖ against appellants, but instead was ―biased‖ in favor
    of its witnesses because of the immensely difficult and dangerous task of
    73
    With regard to the reference to pulling out the weeds, the quote was:
    We have an obligation to get to the truth. We have
    an obligation not to just look at what is right before us,
    but to dig deeper. It’s just like a weed in the sidewalk,
    right? You can pluck off that yellow top, and a
    Dandelion is coming back. We have an obligation to get
    to the root of the problem, and we didn‘t do that with
    Terrence Jones[;] we didn‘t do that. We went forward[;]
    we prosecuted Lannell Cooper alone[;] we didn‘t
    prosecute [D]euce-[D]euce as a whole, and it didn‘t
    work. We can take out Alphonce Little, but there‘s going
    to be somebody else, because Alphonce Little is just the
    weapon in the hands. That‘s our obligation[;] it was to
    do more than just look at what was right before us[;] it
    was our obligation to dig deeper and find the truth, and
    we are firmly convinced that when you go in the back
    and you dig deeper, you will find the truth and when you
    look at all of that evidence in the back you will hold
    these men accountable . . . . [Emphasis added].
    182
    cooperating with the government in a case such as this one.74 When the defense
    objected to this line of argument, the trial court stated that it believed that the
    rebuttal was a fair response to appellants‘ closings. Nevertheless, out of caution,
    the court issued an instruction that the jury was to disregard any reference to the
    personal opinions or ―bias‖ expressed by any of the attorneys during closing
    arguments.
    3. Analysis
    The standard governing our review of prosecutorial misconduct in closing or
    rebuttal argument is ―well-settled.‖ Finch v. United States, 
    867 A.2d 222
    , 225
    (D.C. 2005). ―We start by determining whether the challenged comments were, in
    fact, improper. If they were, we must determine whether the trial judge erred or
    74
    With regard to the government‘s ―bias,‖ the prosecutor argued:
    We‘re not biased against Mr. Cooper or Mr.
    Rushing or Mr. Beaver or Mr. Arnette or Mr. Harris or
    Mr. Tann. We are biased in favor of our witnesses,
    because we ask these folks to come in here and do the
    unthinkable. We ask them to sit on that stand, look at
    you, air all of their baggage and point the finger at these
    men behind me and call them out for what they did. And
    when that happens, they get attacked for it and that‘s the
    way it works. . . .
    So is it personal? Is there a bias? Maybe there is,
    but it’s not against [the defendants]. It’s for those people
    who do what is asked. [Emphasis added].
    183
    abused his discretion in responding to them.‖ 
    Id. ―[A]bsent some
    improper ruling
    or omission by the trial judge, we cannot ordinarily reverse a conviction, and our
    ultimate focus must therefore be on what the judge did or failed to do.‖ Irick v.
    United States, 
    565 A.2d 26
    , 33 (D.C. 1989) (footnote omitted).
    Appellants allege two types of improprieties in the government‘s closing and
    rebuttal arguments. Their first contention is that the government made several
    statements designed to inflame the passions of the jury or urge the jury to send a
    message based on policies apart from the consideration of the evidence, including:
    the argument to the jury about doing the community‘s bidding, the argument that
    ―enough is enough,‖ the reference to ―pulling out the weeds,‖ and the analogy to
    the Italian Mafia. See McGriff v. United States, 
    705 A.2d 282
    , 289 (D.C. 1997);
    Powell v. United States, 
    455 A.2d 405
    , 410 (D.C. 1982). The other assertion made
    by appellants is that the government improperly vouched for the credibility of its
    witnesses by openly declaring, during argument, its bias in favor of them. See
    
    Finch, 867 A.2d at 226
    .
    Even assuming appellants‘ contentions are correct that these remarks by the
    government were improper, we nevertheless find no grounds for reversal. When
    testing for harmlessness in the context of closing and rebuttal arguments, ―this
    184
    court may [] affirm the convictions [if it is] satisfied that the appellant did not
    suffer ‗substantial prejudice‘ from the prosecutor‘s improper comments.‖ 
    Finch, 867 A.2d at 226
    (citing Kotteakos v. United States, 
    328 U.S. 750
    , 765 (1946));
    (Ivery) Gardner v. United States, 
    898 A.2d 367
    , 375 (D.C. 2006) (―where, as
    occurred here, there were multiple instances of asserted improper comments . . . we
    determine whether the cumulative impact of the errors substantially influenced the
    jury‘s verdict‖) (internal quotation marks omitted).
    Factors to be considered in assessing harmlessness include ―the gravity of
    the misconduct, its relationship to the issue of guilt, the effect of any corrective
    action by the trial judge, and the strength of the government‘s case.‖ 
    Irick, 565 A.2d at 32
    . We first note that the government‘s closing and rebuttal arguments
    were very lengthy. Moreover, they were part of an extended period of argument
    by the parties (nearly two weeks) in a trial that lasted nine months from opening
    statements to the final verdict. In comparison, the government‘s alleged missteps
    took the form of relatively brief references amid protracted arguments about the
    complex and numerous facts of the case. See (Vonn) Washington v. United States,
    
    884 A.2d 1080
    , 1089 (D.C. 2005); (Maurice) 
    Morris, 622 A.2d at 1126
    (―the
    185
    offending comment was a relatively brief reference during a lengthy closing
    argument‖) (internal quotation marks omitted).
    Each time that appellants objected, the trial court gave timely and effective
    curative instructions. See 
    McGriff, 705 A.2d at 289
    . We discern no abuse of
    discretion. Moreover, because the government‘s potentially improper remarks
    tended to follow appellants‘ attacks on the motives and strategies of the
    prosecution, many of these arguments were generally collateral and not focused on
    the key matters relevant to the question of appellants‘ guilt. See Bates v. United
    States, 
    766 A.2d 500
    , 510 (D.C. 2000) (remarking on the peripheral nature of the
    improper comments by the prosecutor in evaluating harm).
    The most clearly improper remark – asking the jury to do what the
    community requires – appears to have been inadvertently made; the rest of the
    government‘s remarks are more ambiguous as to their impermissibility. See, e.g.,
    
    Irick, 565 A.2d at 35
    (―Despite decisions in the dozens, the law governing what a
    prosecutor may or may not say about the credibility of a [witness] is not always
    easy to discern or apply.‖) Finally, the jury‘s findings appeared to carefully parse
    through the evidence against each appellant, ultimately acquitting several
    186
    appellants of the most serious charges against them. See Brewer v. United States,
    
    559 A.2d 317
    , 323 (D.C. 1989). Therefore, we can confidently say that appellants
    did not suffer substantial prejudice as a result of any improprieties, taken either
    individually or collectively, in the government‘s arguments.
    D. Discovery
    Appellants make three discovery related arguments. Cooper alone brings a
    claim related to the government‘s loss of his phone calls from jail. All appellants
    bring Brady75 claims involving the government‘s witnesses Dewey Chappell and
    Kyara Johnson.
    1. Loss of Cooper’s Jail Phone Calls
    Cooper argues that the trial court erred in not giving the jury a ―missing
    evidence‖ instruction as a discovery sanction for the government‘s loss of a
    number of his phone calls from jail. There was extensive evidence of jail phone
    calls made by multiple appellants admitted by the parties at trial. In the course of
    the investigation into this case, the prosecutors received a number of CDs
    containing calls made by Cooper from jail between June 2005 and November
    2006. As it was preparing for discovery, the government sent the CDs to its
    75
    Brady v. Maryland, 
    373 U.S. 83
    (1963).
    187
    technology unit for copying. In the process, the recordings of certain calls were
    lost and enough time had passed that the original recordings were no longer
    maintained by the jail. Approximately 90 calls that Cooper made in June 2006
    were estimated to have been lost.
    During pretrial motions, Cooper brought the issue to the attention of the trial
    court and asked the judge to prepare to give the jury a ―missing evidence‖
    instruction. Cooper argued, as he does on appeal, that he would have been able to
    use the contents of the missing calls for the impeachment of government witnesses,
    or alternatively, as nonhearsay verbal acts by him.
    After a motions hearing, the trial court found that the loss by the government
    was unintentional. The court also found that there was no evidence that any of the
    material would have been favorable to Cooper.         Therefore, the court denied
    Cooper‘s request for a missing evidence instruction. However, the court prohibited
    the government from eliciting testimony from any witness about conversations that
    would have been on the missing calls.          Additionally, parties introduced a
    stipulation into evidence stating, in essence, that the June 2006 calls were lost by
    the government and efforts to recreate them had failed.
    188
    Cooper argues that the trial court erred in refusing to give the ―missing
    evidence‖ instruction, i.e., that:
    If evidence relevant to an issue in this case was only
    within the power of one party to produce, was not
    produced by that party, and its absence has not been
    sufficiently explained, then you may, if you deem it
    appropriate, infer that the evidence would have been
    unfavorable to the party who failed to produce it.
    However, you should not draw such an inference from
    evidence that in your judgment was equally available to
    both parties or which would have duplicated other
    evidence or that you think was unimportant.
    Criminal Jury Instructions for the District of Columbia, No. 2.300 (5th ed. rev.
    2013).
    Superior Court Criminal Rule 16 (a)(1)(A) requires the government to
    disclose to the defendant any relevant written or recorded statements made by the
    defendant of which it has knowledge, or that it would discover in the exercise of
    due diligence, and to make those statements available to the defense for inspection,
    copying, or photographing. This court has noted that ―[t]he duty to produce
    discoverable evidence entails the antecedent duty to preserve that evidence.‖ Allen
    v. United States, 
    649 A.2d 548
    , 553 (D.C. 1994).
    189
    If a trial court concludes that the government‘s failure to preserve evidence
    constituted a violation of Rule 16, ―[i]n fashioning the appropriate sanction, the
    court should weigh the degree of negligence or bad faith involved, the importance
    of the evidence lost, and the evidence of guilt adduced at trial.‖         (Anthony)
    Robinson v. United States, 
    825 A.2d 318
    , 331 (D.C. 2003). The trial court may
    select from the ―extremely broad‖ range of sanctions for corrective action that is
    ―just under the circumstances.‖ Tyer v. United States, 
    912 A.2d 1150
    , 1165 (D.C.
    2006). ―We review the denial of a request for a missing evidence instruction for
    abuse of discretion,‖ 
    id. at 1164,
    and we ―will not reverse the trial court‘s decision
    as to what sanctions, if any, to impose . . . unless there is an error which has
    substantially prejudiced a defendant‘s rights.‖ 
    Allen, 649 A.2d at 553
    (emphasis
    omitted).
    The government agrees with Cooper that the recorded jail calls were
    discoverable and does not dispute the trial court‘s characterization of the
    government‘s loss of the recordings as the result of ―substantial negligence‖ and
    ―real carelessness‖ constituting a Rule 16 violation. However, our review of the
    record supplies no basis for this court to disturb the trial judge‘s conclusion
    regarding the minimal importance of the missing evidence to the defense
    190
    (particularly in light of the doubts he properly expressed regarding whether Cooper
    would have been able to make use of any of the statements that may have been
    contained in the lost recordings).76 
    Tyer, 912 A.2d at 1166
    .
    Because the missing evidence instruction ―essentially creates evidence from
    non-evidence,‖ we have said that trial courts should take care that its use does not
    unfairly change ―the tone of the evidence‖ or invite the jury to ―give undue weight
    to the presumed content of testimony not presented.‖ Id.; Thomas v. United States,
    
    447 A.2d 52
    , 58 (D.C. 1982). Any claim of prejudice that Cooper makes related to
    the trial court‘s refusal to administer a missing evidence instruction is undermined
    by the corrective measures that the trial court did employ, which included both a
    prohibition against the government eliciting any testimony regarding the contents
    of the missing calls, and the administration of a stipulation informing the jury that
    the calls had been lost while in possession of the government. Therefore, we find
    no abuse of discretion in the trial court‘s choice of remedy.
    76
    Cooper, even on appeal, has not provided any specificity as to how he
    would have used the contents of the calls.
    191
    2. Dewey Chappell
    Dewey Chappell was a government witness with ties to appellants and the
    22nd Street Crew. He was arrested for unrelated criminal activity on January 23,
    2009, as this trial was ongoing. Subsequently, he became a cooperating witness
    for the government. His testimony was focused on the efforts of Cooper and others
    to obstruct justice with regard to the Johnson sisters in the aftermath of the
    Terrence Jones murder, and Harris‘s flight into hiding following the James Taylor
    murder.
    Prior to his testimony, the government made extensive disclosures related to
    Dewey Chappell‘s criminal history and other potential impeachment material. As
    part of these disclosures, the government informed appellants that a gun had been
    taken by law enforcement from Chappell‘s home on January 23, 2009, during his
    arrest.     The government also disclosed that Chappell‘s fingerprints had been lifted
    from the gun.
    Dewey Chappell was impeached extensively on bias by various defense
    counsel during his cross-examination. After the government rested its case, and
    during the defense cases-in-chief, the National Integrated Ballistics Network
    192
    (―NIBN‖) made the government aware that there was a possible link between the
    gun that had been taken from Chappell‘s home and a homicide that occurred in
    January 2009 prior to his arrest. The government did not disclose this fact to the
    defense.
    The government also made a conscious effort not to discuss the matter with
    Dewey Chappell so that he would not be aware of the link, and therefore he would
    not have any additional motive to curry favor with the government. About a week
    later, while the defense cases were still ongoing, the match was confirmed by
    NIBN.
    However, Dewey Chappell was apparently never considered a suspect by the
    government in the January 2009 murder. After the merits portion of this trial
    ended, but before sentencing, Chappell was debriefed about the ballistic link and
    told investigators that he was unaware of any facts related to that homicide. He
    also indicated that the gun found at his home belonged to a person who previously
    stored it at the home of Chappell‘s relative. Chappell had agreed to take the
    weapon and store it at his house once police started ―snooping around‖ his
    relative‘s home.
    193
    Before sentencing was conducted, the government reversed course and
    decided to disclose the ballistics information to appellants. However, the
    government argued that there was no discovery violation because the information
    would not have been relevant unless Dewey Chappell had known of the ballistics
    link at the time that he testified for the government. Therefore, he had no reason to
    curry favor with the government through cooperation.
    All appellants argued that they were entitled to a new trial. Their argument
    was that by not disclosing the information, the government prevented them from
    (1) cross-examining Dewey Chappell on his perceived fear of prosecution for the
    January 2009 homicide, (2) showing that Chappell was hiding a weapon and
    therefore hindering the January 2009 homicide investigation, and (3) investigating
    the possible connection between that weapon and the murders of which appellants
    were convicted in this case. After a hearing, the trial court denied appellants‘
    motions for a new trial, finding no discovery violation. Appellants now renew
    their claims, in essence, on appeal.
    Brady issues are mixed questions of law and fact. Mackabee v. United
    States, 
    29 A.3d 952
    , 959 (D.C. 2011). While a trial court‘s findings of ―historical
    194
    fact‖ are reviewed for clear error, where the court‘s findings ―concern[] the legal
    consequences of historical facts,‖ they are reviewed de novo.            
    Id. (internal quotation
    marks omitted).
    ―[T]he suppression by the prosecution of evidence favorable to an accused
    upon request violates due process where the evidence is material either to guilt or
    punishment, irrespective of the good faith or bad faith of the prosecution.‖ 
    Brady, 373 U.S. at 87
    ; (Wesley) 
    Williams, 881 A.2d at 561
    . ―The evidence is material
    only if there is a reasonable probability that, had the evidence been disclosed to the
    defense, the result of the proceeding would have been different.‖          
    Id. at 562
    (quoting United States v. Bagley, 
    473 U.S. 667
    , 682 (1985)).           Such material
    evidence may include impeachment matters. (Michael) Robinson v. United States,
    
    50 A.3d 508
    , 519 (D.C. 2012).
    The non-disclosure concerning Dewey Chappell was not material under
    Brady, and we find no grounds for relief. ―Impeachment evidence is not material
    if the witness does not have knowledge of the underlying fact.‖ Ifelowo v. United
    States, 
    778 A.2d 285
    , 295 n.13 (D.C. 2001) (quoting Williams v. Scott, 
    35 F.3d 159
    , 162 (5th Cir. 1994)); Blunt v. United States, 
    863 A.2d 828
    , 835 (D.C. 2004)
    195
    (―When evaluating the possibility of bias in adverse testimony, the objective
    likelihood of prosecution and the subjective intent of the government to prosecute
    are irrelevant[.] Rather, it is the witness‘ belief that prosecution is possible that
    can produce bias.‖) (citations and internal quotation marks omitted).        This is
    because, of course, a witness cannot be motivated to act in a certain way if he has
    no knowledge that he should be motivated to do so.
    Here, there is no evidence that Dewey Chappell was aware of the NIBN
    finding linking the weapon found at his house to the January 2009 homicide. In
    fact, the government went out of its way to avoid exposing Chappell to knowledge
    of the ballistic link so that he would not have motive to ―curry favor‖ and avoid
    prosecution. Therefore, the undisclosed evidence lacked the necessary impeaching
    qualities so as to be material under Brady.
    Moreover, on this record, we see no evidence that would suggest that the
    ballistics information had investigatory value to appellants such that its non-
    disclosure would have violated the government‘s disclosure obligations.
    
    Mackabee, 29 A.3d at 961
    (mere speculation that evidence might have led to
    discovery of exculpatory evidence insufficient to establish a Brady violation).
    196
    Finally, we agree with the trial court that the extensive cross-examination of
    Dewey Chappell on issues related to bias, including based on the weapon that was
    found in his home, was such that had the ballistic evidence been disclosed there
    was still no reasonable possibility that the results of this case would have been
    different. See 
    Fortson, 979 A.2d at 662-63
    ; Watson v. United States, 
    940 A.2d 182
    , 187-88 (D.C. 2008).
    3. Kyara Johnson
    Kyara Johnson, as an eyewitness to both the Terrence Jones and Laquanda
    Johnson murders, was a critical government witness. She testified in Cooper‘s
    2006 trial about Terrence Jones‘s murder, and again in this trial about that murder
    and her sister‘s. In the weeks following Laquanda‘s murder, Kyara gave grand
    jury testimony about the night of Laquanda‘s death. Before the grand jury, Kyara
    testified that she saw Alphonce Little flee the scene of the crime by jumping on the
    back of a moped driven by another man wearing his hair in dreadlocks and
    carrying a gun. At trial, however, she testified on direct-examination that she
    heard a moped but had not seen Little driven away on one.
    On cross-examination, Kyara Johnson acknowledged that she had lied in the
    grand jury. She also testified that she had informed the government that she had
    197
    been told the story about Alphonce Little and the moped by her friend Shaquita
    Long. Apparently, the fact that Kyara was told about the moped by Long was not
    previously known to appellants before this testimony. During a break in cross-
    examination, appellants made motions alleging a discovery violation.     Rushing
    claimed that Long was an exculpatory witness because her testimony would
    support a version of events where Little was not escorted from the murder scene by
    Rushing and Beaver in Rushing‘s car.      Beaver and Rushing, joined by Cooper,
    renew that claim on appeal.
    The government responded that Kyara Johnson‘s grand jury testimony about
    Alphonce Little and the moped had long been available to the defense.
    Additionally, the government proffered, Shaquita Long told the government at the
    outset of the investigation into Laquanda Johnson‘s murder that she never saw
    Little drive away on a moped. Instead, Long informed the government that she
    saw various 22nd Street Crew members driving on 22nd Street on a moped about
    an hour before the shooting.
    The trial court found no discovery violation, but ordered the government to
    make Long available to appellants for interviewing. The court also offered to
    198
    allow appellants to reopen their cases, if necessary, to the extent that Long could
    not be located prior to the completion of their cases (which were scheduled to
    begin three days after Kyara Johnson‘s testimony for the government finished).
    We find no Brady violation based on these facts involving Kyara Johnson
    and Long. Defense counsel acknowledged that they knew of the inconsistency
    between Alphonce Little‘s and Kyara‘s version of events and used it to cross-
    examine both of them concerning the moped. Rushing went on to argue in closing
    that the inconsistency undermined Little‘s credibility.
    As far as Long was concerned, the government proffer was unchallenged
    that she would testify that she never saw a moped. This fact renders immaterial the
    government‘s ―failure‖ to identify her as the source of Kyara Johnson‘s
    information for her grand jury testimony.         Our finding of immateriality is
    supported by the fact that defense counsel never made any further mention of
    Long. Nor did they ask for any sort of continuance in order to interview Long, or
    subpoena her for trial, despite the express invitation of the trial court to do so.
    (Wesley) 
    Williams, 881 A.2d at 563
    (importance of potentially exculpatory
    199
    witnesses decreases where no attempt is made to receive a continuance in order to
    investigate their testimony).
    E. Grand Jury Claims
    Appellants Tann, Arnette, and Harris bring three claims raised at trial based
    on the government‘s misuse of the grand jury: two focused on improprieties in the
    pre-indictment process and a third alleged abuse of the grand jury after the
    superseding indictment in this case was handed down. Pre-indictment, appellants
    argue that the government improperly influenced the grand jury process by
    summarizing testimony given to previous grand juries instead of calling live
    witnesses; appellants also contend that prosecutors presented incompetent evidence
    to the grand jury in violation of Tann‘s marital privilege.              Post-indictment,
    appellants contend that the government unlawfully used the grand jury as a
    discovery tool when prosecutors called a witness to the grand jury for purposes of
    ―locking-in‖ his testimony after appellants had already been indicted. We find that
    the trial court did not abuse its discretion in handling these matters at trial.
    Therefore, appellants are entitled to no relief based on their claims.
    Two grand juries were convened and issued indictments against appellants.
    In October 2007, a grand jury indicted all appellants except Rushing. In February
    200
    2008, after Alphonce Little gave the government new information about Rushing‘s
    role in the Laquanda Johnson murder, a second grand jury handed down the
    superseding indictment upon which the government proceeded in this case.
    Apparently, the only new evidence presented to the second grand jury was the
    testimony of Detective Mayberry reciting Rushing‘s recently discovered
    involvement in Laquanda‘s murder. The prosecutor also summarized numerous
    transcripts of testimony from previous grand jury investigations, and then
    prosecutors left those transcripts and accompanying exhibits with the grand jury
    for its consideration.77
    During the testimony of Tracey Tann, the issue of marital privilege was
    raised. The Tanns were married in April 2004 – approximately one year after the
    Leslie Jones murder. Prior to their marriage, Tann told Tracey that he killed a man
    named ―Bone‖ (Leslie Jones‘s nickname) on 22nd Street. On cross-examination,
    Tann‘s defense counsel elicited the discrepancy between the location where Tracey
    testified that Tann told her the murder was committed (22nd Street), and the
    location where it actually occurred (Shipley Market), in an attempt to undermine
    77
    The government represented that the reason summaries were provided
    was that the transcripts, which referenced exhibits, would not make sense to the
    reviewing grand jury without explanation.
    201
    her testimony. In response, the prosecution sought to introduce, on re-direct,
    Tracey‘s grand jury testimony to the effect that after their marriage Tann told her
    (in confidence) that he had actually committed the murder at Shipley Market.
    The trial court recognized the marital privilege issue and noted that Tracey
    could not testify to that fact at trial. Moreover, after reviewing her grand jury
    testimony, the court found that Tracey should not have testified about that
    privileged statement before the grand jury.   At trial, Tann and Harris, now joined
    by Arnette on appeal, argued for dismissal of the indictment based on Tracey‘s
    incompetent testimony and the prosecutor‘s summarizing of evidence to the grand
    jury. The trial judge, relying primarily on Bank of Nova Scotia v. United States,
    
    487 U.S. 250
    (1988), rejected both of appellants‘ pre-indictment claims.
    The final grand jury issue was raised during discussions about the
    anticipated testimony of a government witness, Willie Jones. The government
    intended to call Willie Jones to describe a conversation that he had with Tann, after
    the Terrence Jones murder, in which Tann told him that Tann had approached a
    different government witness in a threatening manner. Tann objected, essentially,
    on grounds that the proffered testimony was vague and irrelevant.              After
    202
    reviewing Willie Jones‘s grand jury testimony in the course of ruling on the
    objection, the trial court noticed that his testimony was given after the date of the
    superseding indictment in this case.
    Sua sponte, the court raised the issue that it was improper to call witnesses to
    participate in grand jury investigations in order to obtain evidence on already
    indicted cases. The government represented that Willie Jones was subpoenaed to
    give evidence on other unindicted murders still under investigation by the grand
    jury. The government further proffered that it had learned that Willie Jones had
    facts relevant to the instant case during a pre-grand jury interview. According to
    the government, Willie Jones then testified about the facts of this case incidental to
    his testimony about other unindicted matters.
    The court disagreed with the government‘s representations and found that
    Willie Jones‘s testimony about the already indicted offenses in this case was the
    dominant purpose of his grand jury appearance. However, after a series of
    pleadings and hearings, the court found that it would be inappropriate to prohibit
    Willie Jones from testifying because the government properly uncovered the
    information underlying his testimony during a pre-grand jury interview pursuant to
    203
    a lawfully issued subpoena. Instead, the court ruled that the proper remedy would
    be to prohibit the government from using Willie Jones‘s grand jury testimony in
    any way during trial.
    1. Pre-indictment
    ―[A]s a general matter, a [federal] court may not dismiss an indictment for
    errors in grand jury proceedings unless such errors prejudiced the defendants.‖
    Bank of Nova 
    Scotia, 487 U.S. at 254
    ; (Phillip) Williams v. United States, 
    757 A.2d 100
    , 105 (D.C. 2000) (adopting the same standard for District of Columbia
    courts). Except for cases involving ―fundamental‖ errors ―in which the structural
    protections of the grand jury have been so compromised as to render the
    proceedings fundamentally unfair,‖ dismissal of the indictment is appropriate only
    ―if it is established that the violation substantially influenced the grand jury‘s
    decision to indict, or if there is grave doubt that the decision to indict was free from
    the substantial influence of such violations.‖ (Phillip) 
    Williams, 757 A.2d at 105
    (internal quotation marks omitted) (quoting Bank of Nova 
    Scotia, 487 U.S. at 256
    -
    57).
    Here, the record clearly reflects that the trial court applied and quoted the
    correct standard from Bank of Nova Scotia in deciding whether to dismiss the
    204
    indictment despite the improper exposure of privileged marital testimony to the
    grand jury.78 Similar to the record in (Phillip) Williams, the record in this case
    shows that the grand jury had compelling evidence before it other than the
    testimony admitted in error.      Specifically, the grand jury heard premarital
    testimony from Tracey describing how Tann killed a man named ―Bone,‖ who was
    related to one of his rivals.      Therefore, Tracey‘s incompetent post-marital
    testimony was largely cumulative with her testimony that was properly before the
    grand jury.   Furthermore, the grand jury had powerful testimony from two
    eyewitnesses describing Leslie Jones‘s murder: Alphonce Little, testifying that he
    saw Tann shoot Leslie Jones, and Tyrone Curry, describing how he heard gunshots
    and observed Tann run from the scene of the shooting immediately thereafter.
    Consequently, the trial court correctly concluded that the premarital
    statements, and other evidence going to Tann‘s murder of Leslie Jones, were
    78
    See D.C. Code § 14-306 (b) (2012 Repl.) (―In civil and criminal
    proceedings, a spouse or domestic partner is not competent to testify as to any
    confidential communications made by one to the other during the marriage or the
    domestic partnership.‖); (Cotey) Wynn v. United States, 
    48 A.3d 181
    , 189 (D.C.
    2012) (―[t]he word ‗proceeding‘ may comfortably be used to describe
    investigations by a grand jury‖); In re Grand Jury Investigation, 
    431 F. Supp. 2d 584
    , 592 (E.D. Va. 2006) (―[I]t is . . . well-established that the marital privilege
    may be invoked during grand jury testimony.‖) (citing United States v. (Thomas)
    Morris, 
    988 F.2d 1335
    , 1337 (4th Cir. 1993)).
    205
    ―compelling evidence‖ for the grand jury to find probable cause even setting aside
    the privileged post-marital testimony. We find that the problematic testimony did
    not ―raise a substantial question, much less a grave doubt, as to whether [it] had a
    substantial effect on the grand jury‘s decision to charge.‖ Bank of Nova 
    Scotia, 487 U.S. at 263
    .
    Appellants‘ argument about the way in which testimony was presented to the
    grand jury which issued the superseding indictment amounts to the type of
    reliability challenge which, on these facts, also does not establish prejudice under
    the Bank of Nova Scotia standard. See 
    id. at 262-63
    (determining that dismissal of
    indictment not warranted on the basis of a reliability challenge to the accuracy of
    IRS agents‘ tandem reading of transcripts before the grand jury given no showing
    of prejudice). Regarding the use of transcripts in the grand jury generally, we note
    that this court has ―sanctioned the prosecutor‘s use of a transcript of a witness‘
    prior sworn grand jury testimony in a later, separate grand jury proceeding.‖ Miles
    v. United States, 
    483 A.2d 649
    , 654 (D.C. 1984); see also United States v.
    Calandra, 
    414 U.S. 338
    , 344-45 (1974) (―The grand jury‘s sources of information
    are widely drawn, and the validity of an indictment is not affected by the character
    of the evidence considered.‖)
    206
    As to the prosecutor‘s summaries of the testimony contained in the
    transcripts that were presented to the grand jury, we find that the record does not
    reflect ―any attempt by the prosecutor to deceive the grand jury.‖ 
    Miles, 483 A.2d at 654
    . The prosecutor represented, without contradiction, that she accurately
    summarized the testimony in the transcripts and left the transcripts with the grand
    jury for its review. Indeed, the prosecutor also stated that the second grand jury
    was correctly alerted that Alphonce Little had perjured himself before the prior
    grand jury. Where there is no indication that the grand jury was in any way misled
    based on the manner of the government‘s presentation of the evidence, we have no
    basis to find that the trial court abused its discretion in refusing to dismiss the
    indictment.
    2. Post-Indictment
    Finally, with regard to the trial court‘s fashioning of an appropriate remedy
    for the government‘s improper elicitation from Willie Jones before the grand jury
    of information concerning already indicted matters, we again review for an abuse
    of discretion, and find none. See United States v. Breitkreutz, 
    977 F.2d 214
    , 217
    (6th Cir. 1992) (reviewing for abuse of discretion the trial court‘s denial of the
    defendant‘s motion to grant appropriate relief based on allegations of post-
    indictment government misuse of the grand jury to ―‗lock-in‘ incriminating
    207
    testimony‖).   ―While a grand jury wields broad investigatory powers prior to
    returning an indictment, courts uniformly have held that, once a targeted individual
    has been indicted, the government must cease its use of the grand jury in preparing
    its case for trial.‖ See Resolution Trust Corp. v. Thornton, 
    41 F.3d 1539
    , 1546
    (D.C. Cir. 1994) (internal quotation marks and alterations omitted); see also
    Beverly v. United States, 
    468 F.2d 732
    , 743 (5th Cir. 1972) (―It is a misuse of the
    grand jury to use it as a substitute for discovery.‖).
    However, in fashioning an appropriate remedy where a post-indictment
    violation of the grand jury process has occurred, federal courts impose one that
    ―fit[s] the circumstances of the particular case.‖        See, e.g., United States v.
    Kovaleski, 
    406 F. Supp. 267
    , 271 (E.D. Mich. 1976). We believe this is the
    rational and proper standard for trial courts to apply.
    Here, the trial court‘s decision to bar the government from using Willie
    Jones‘s grand jury testimony at trial put the government in exactly the same
    position it would have been in absent its misuse of the grand jury. The government
    learned relevant information from Willie Jones during a proper pre-grand jury
    interview and could have subpoenaed him directly as a trial witness, rather than
    208
    having him testify at the grand jury on already indicted matters. It is unchallenged
    that the government had a legitimate purpose in originally subpoenaing Willie
    Jones to the grand jury; namely, to learn about unindicted matters under
    investigation.
    Accordingly, given these facts, the trial court‘s choice of remedy – to permit
    the government to call Willie Jones as a witness but to prohibit it from using his
    grand jury testimony in any way – seems fitting and not in error. Cf. 
    id. at 271
    (precluding the government from calling the witness at trial was ―the only effective
    remedy‖ on the facts of that case). Therefore, appellants‘ grand jury claims are
    denied.
    X. Merger
    Appellant Tann argues for merger of the following convictions: (1) his three
    convictions for second-degree murder of Terrence Jones, (2) his three PFCV
    convictions arising out of the Terrence Jones murder, (3) his two PFCV
    convictions arising out of the James Taylor-Bernard Mackey incident, (4) his two
    PFCV convictions arising out of the armed robbery and AWIKWA of Richard
    Queen, and (5) his PFCV convictions arising out of the Queen facts with his PFCV
    convictions arising out of the Terrence Jones facts.
    209
    Appellant Arnette joins Tann as to arguments (1) and (2). The government
    concedes arguments (1), (2), and (3), but contends that Tann‘s two PFCV
    convictions for the armed robbery and AWIKWA of Richard Queen do not merge
    with each other or with his remaining PFCV conviction for the Terrence Jones
    murder. This court reviews merger issues de novo. Nero v. United States, 
    73 A.3d 153
    , 159 (D.C. 2013).
    The Double Jeopardy Clause protects defendants against multiple
    punishments for the same offense, but does not prohibit multiple punishments for
    ―separate criminal acts.‖ Owens v. United States, 
    497 A.2d 1086
    , 1094-95 (D.C.
    1985). ―[A]s a general rule, where two predicate armed offenses do not merge, a
    defendant may be convicted of separate counts of PFCV relating to each offense
    . . . .‖ Stevenson v. United States, 
    760 A.2d 1034
    , 1035 (D.C. 2000). The rule,
    however, is susceptible to a limited exception: ―multiple PFCV convictions will
    merge, even if the predicate felony offenses do not merge, if they arise out of a
    defendant‘s uninterrupted possession of a single weapon during a single act of
    violence.‖ Matthews v. United States, 
    892 A.2d 1100
    , 1106 (D.C. 2006); see also
    Nixon v. United States, 
    730 A.2d 145
    , 153 (D.C. 1999) (applying the rule of lenity
    210
    and holding that three PFCV convictions merged into one where the defendant
    fired several times into a car containing multiple victims).
    In determining whether multiple PFCV convictions are based on a single act
    or distinct acts of violence, we apply the so-called ―fork-in-the-road‖ or ―fresh
    impulse‖ test. 
    Matthews, 892 A.2d at 1106
    ; 
    Stevenson, 760 A.2d at 1037
    (―If at
    the scene of the crime the defendant can be said to have realized that he has come
    to a fork in the road, and nevertheless decides to invade a different interest, then
    his successive intentions make him subject to cumulative punishment . . . .‖).
    Under that test, Tann‘s PFCV convictions related to the robbery and
    shooting of Richard Queen do not merge. Donald Matthews testified that Tann
    and other men pinned Queen against a car, beat him, and went through his pockets,
    that Queen tried to run away, and that Tann picked up a gun that had fallen to the
    ground and shot Queen in the back. Tann reached a ―fork-in-the-road‖ and had the
    opportunity for a ―fresh impulse‖ when Queen began to run and Tann picked up
    the gun and made the decision to shoot. See 
    Baker, 867 A.2d at 1010
    ; Sanders v.
    United States, 
    809 A.2d 584
    , 604 (D.C. 2002); 
    Stevenson, 760 A.2d at 1037
    -38.
    211
    Similarly, Tann‘s Richard Queen-related PFCV convictions do not merge
    with his PFCV conviction for aiding and abetting Cooper‘s murder of Terrence
    Jones. Tann argues that the convictions should merge because the Terrence Jones-
    Richard Queen incident ―was a rapidly developing, short-lived assaultive event.‖
    However, in 
    Harrison, 76 A.3d at 826
    , we concluded that two defendants‘
    convictions for AWIKWA and first-degree felony murder did not merge on facts
    showing that one defendant shot one victim at nearly the same time as the other
    defendant shot a second victim. 
    Id. at 831-32.
    We also held that the defendants‘
    resulting PFCV convictions did not merge because the ―separate shootings arose
    from fresh impulses and targeted different victims.‖ 
    Id. at 844;
    see also Wages v.
    United States, 
    952 A.2d 952
    , 964 (D.C. 2008) (PFCV convictions for the shooting
    of different victims merge only when ―there was a single shooting incident, that is,
    one assaultive act that resulted in multiple victims‖). In the same way, Tann‘s
    PFCV associated with his robbery and shooting of Richard Queen does not merge
    with his PFCV related to Cooper‘s shooting of Terrence Jones because the two
    PFCV offenses involved ―separate assaulting acts.‖ 
    Harrison, 76 A.3d at 844
    .
    Therefore, we leave unmerged his PFCV convictions arising out of the armed
    robbery and AWIKWA of Richard Queen.
    212
    XI. Conclusion
    In the final analysis, we reverse the judgment at trial as to the following:
    Beaver‘s CPWL judgment of conviction, Arnette‘s PFCV judgment of conviction
    related to the armed robbery of Richard Queen, and Arnette‘s judgment of
    conviction for armed robbery. We remand the case to the trial court with the
    following instructions: (1) to enter a judgment of conviction against Arnette for
    the lesser-included offense of robbery79 and (2) to merge the following judgments
    of conviction – Tann‘s three judgments of conviction for second-degree murder of
    Terrence Jones, Arnette‘s three judgments of conviction for second-degree murder
    of Terrence Jones, Tann‘s three PFCV judgments of conviction associated with his
    convictions for the murder of Terrence Jones, Arnette‘s two remaining PFCV
    judgments of conviction arising out of the murder of Terrence Jones, and Tann‘s
    two PFCV judgments of conviction arising out of the James Taylor-Bernard
    Mackey incident. In all other respects, the judgments of conviction are affirmed.
    So ordered.

    213
    GLICKMAN, Associate Judge, concurring in part and dissenting in part: For
    the most part, I join the per curiam opinion disposing of the appeals in these
    several cases. I cannot join Section VII.C, however. In that section, my colleagues
    hold that appellants Harris and Tann could be liable for aiding and abetting Robert
    Foreman‘s shooting of James Taylor and Bernard Mackey even if Harris and Tann
    were unaware of Foreman‘s presence or actions and did not intend to assist or
    encourage Foreman in his criminal activity.        I believe my colleagues in the
    majority base that holding on an erroneous theory of accomplice liability—a novel
    theory of their own devising, and one not relied on at trial or argued on appeal.
    As the per curiam opinion explains in more detail, the shootings occurred on
    May 4, 2006, at a playground on 22nd Street Southeast.             According to the
    government‘s proof at trial, after Omar Harrison verbally abused and slapped
    Ashley Tyndle, several members of the 22nd Street Crew, including Harris and
    Tann, rushed to Tyndle‘s defense. Harris and Tann fired several shots at Harrison.
    Foreman, another member of the Crew, arrived on the scene a few moments later
    and, unbeknownst to Harris and Tann, independently decided to join in the
    shooting. Foreman missed Harrison but the evidence supported a finding that he
    hit, and killed, Taylor. He also may have fired the shot that injured Mackey. Over
    appellants‘ objections, the trial court instructed the jury that Harris and Tann could
    214
    be found guilty for these two shootings as aiders and abettors based on their
    participation in ―the crime‖ (i.e., their own shooting at Harrison) even if they did
    not knowingly or intentionally assist or encourage the principal assailant (i.e.,
    Foreman). The jury found Harris and Tann guilty of first-degree murder while
    armed for Taylor‘s death and of assault with intent to kill while armed for the
    wounding of Mackey.
    The fundamental issue on which I differ with my colleagues is whether a
    person can be found guilty as an aider and abettor under the law of the District of
    Columbia without proof that he intended to assist or encourage the principal
    offender. I think not. Sitting en banc, we declared in Wilson-Bey that it is a
    ―requirement [for aiding and abetting liability] that the accomplice be shown to
    have intended that the principal succeed in committing the charged offense.‖ 1 We
    elaborated, in a subsequent decision, that this court has ―adopted the doctrine that
    ‗in order for a person to be held accountable for the specific intent of another under
    an aiding and abetting theory of principal liability, the aider or abettor must have
    knowingly aided the other person with the intent that the other person commit the

    903 A.2d 818
    , 831 (D.C. 2006) (en banc).
    215
    charged crime.‘‖2 This core requirement has a long history, which is reviewed in
    Judge Learned Hand‘s influential opinion defining accomplice liability under
    federal law in United States v. Peoni.3 The Supreme Court endorsed Hand‘s
    definition in Nye & Nissen v. United States,4 and it now is well settled that ―the
    specific intent to facilitate the commission of a crime by another‖ is an essential
    element of aiding or abetting under the general federal aiding and abetting statute,
    18 U.S.C. § 2.5 ―The intent necessary to support a conviction for aiding and
    abetting goes beyond the mere knowledge that the defendant‘s action would tend
    to advance some nefarious purpose of the principal. Rather, the defendant must act

    associate himself with the [principal‘s] venture, that he participate in it as in
    something that he wishes to bring about, that he seek by his action to make it
    succeed‖).

    , 849 (D.C. Cir. 1982)); see also, e.g.,

    134 S. Ct. 1240
    , 1245 (2014) (―[U]nder §2 ‗those who
    provide knowing aid to persons committing federal crimes, with the intent to
    facilitate the crime, are themselves committing a crime.‘‖) (quoting Central Bank

    216
    with the specific intent of facilitating or advancing the principal‘s commission of
    the underlying crime.‖6 Because ―our aiding and abetting statute does not differ
    substantially from its federal counterpart,‖ we ―look to the federal courts‘
    interpretation of the federal statute in construing our own.‖7
    Thus, contrary to the position espoused by the government and implemented
    by the trial court in this case,8 for a defendant to be liable as an aider or abettor, ―it
    is not sufficient that he intentionally engaged in acts which, as it turned out, did
    give assistance or encouragement to the principal‖; in addition, ―the accomplice

    (internal quotation marks and brackets
    omitted).
    8
    The government‘s position, at trial and on appeal, is that ―it is an
    accomplice‘s intentional participation in a crime, not his association with a
    principal, that gives rise to aiding and abetting liability.‖ Br. for Appellee at 204.
    The government thus argues that Harris and Tann were aiders and abettors if, by
    shooting at Harrison, they ―incited‖ Foreman to join in the attack, even if they did
    so unknowingly and unintentionally. The trial court instructed the jury in
    accordance with this theory. But the government has cited no authority supporting
    its claim that unintentional incitement can constitute aiding and abetting. Cf.
    BLACK‘S LAW DICTIONARY 880 (10th ed. 2014) (defining ―incitement‖ in the field
    of criminal law as ―[t]he act of persuading another person to commit a crime‖).
    Nor has the government been able to find any case, from any jurisdiction, holding
    a defendant liable as an aider and abettor for the independent criminal act of
    another that the defendant did not intentionally encourage or assist in some way.
    217
    must have intended to give the aid or encouragement‖ to the principal.9 For the
    same reason, it is not sufficient that the defendant merely had the same mens rea as
    the principal.10 There is ―a dual mental state requirement‖ for accomplice liability:
    the accomplice not only must have ―the culpable mental state required for the
    underlying crime committed by the principal‖; he also must ―assist[] or
    encourage[] the commission of the crime committed by the principal with the
    intent to promote or facilitate such commission.‖11
    This does not mean the accomplice always must know the identity of the
    principal offender. It almost always is the case, of course, that an accomplice does
    know whom he is intentionally assisting or encouraging to commit an offense,
    because they are co-participants in the venture (even if the accomplice may not

    We have held that ―where a specific mens rea is an element of a criminal

    know the principal‘s name). But it is possible in some circumstances to be an aider
    and abettor – to help or induce another person to commit a crime, and to do so
    knowingly and intentionally – without knowing who that other person is. A typical
    example is the person who knowingly attaches himself to a large group, such as a
    lynch mob, a criminal gang, or a vigilante body, that is engaged in or bent on
    breaking the law. Such a person may intentionally assist or encourage others in the
    group to commit illegal acts, and thereby be liable for their offenses as an aider and
    abettor, even though (given the size of the group, the chaos of the action, or other
    circumstances) he may not know who is in the group or who the principal
    offenders in it are.12 But one cannot be liable as an aider and abettor without
    having the intent to assist or encourage a principal actor at all. One cannot be an
    inadvertent accomplice.
    The trial court therefore erred in allowing the jury to find Harris and Tann
    guilty on the government‘s novel theory that they aided and abetted Foreman if, by
    shooting at Omar Harrison themselves, they unknowingly and unintentionally
    ―incited‖ Foreman to join in the attack.       It is beside the point that Foreman

    72 P.2d 609

    intended to aid and abet Harris and Tann; that has things backwards. Accomplice
    liability depends on whether the accomplice intended to encourage or assist the
    principal, not on whether the principal intended to encourage or assist the
    accomplice.
    My colleagues agree that the trial court erred by instructing the jury in
    accordance with the government‘s theory of aiding and abetting. Yet in spite of
    their agreement on this point, they affirm appellants‘ convictions on the basis of a
    novel theory of their own devising that suffers from the same defects as the
    government‘s theory. Under this theory, Harris and Tann are liable as Foreman‘s
    accomplices even if they did not intend to encourage or assist Foreman, because
    (1) they shared a ―community of purpose‖ with Foreman and (2) it was reasonably
    foreseeable that their actions would inspire someone who shared their community
    of purpose to commit the crime.13
    To evaluate this theory of aiding and abetting liability without intentional
    support for the principal, it is important to understand two things about its central
    concepts.     First, the term ―community of purpose‖ does not imply concerted
    13
    See ante at 74.
    220
    activity on the part of the principal and putative accomplice. According to my
    colleagues, the requisite ―community of purpose‖ may exist in the absence of any
    agreement, understanding, or cooperation between them with respect to the crime
    in question; indeed, they may be unaware of each other and acting independently,
    albeit to the same criminal end.14 Second, and most critically, my colleagues‘
    theory of accomplice liability treats reasonable foreseeability as the legal
    equivalent of intentionality.15
    This represents a considerable expansion of the doctrine of accomplice
    liability, for, as discussed above, it is a basic requirement in American criminal law
    that an accomplice actually ―must intend that his acts have the effect of assisting or
    encouraging‖ the principal.16 That the putative accomplice reasonably should have
    foreseen the principal‘s actions (and, for that matter, that he would have approved
    14
    Ante at 77 n.28; see also ante at 75 n.27 (―[A] ‗community of purpose‘
    necessarily implies that there exists some tacit, if not always explicit, agreement or
    understanding between all involved (such as a code of conduct), even if there is no
    agreement to commit a specific crime.‖ (majority‘s emphasis)).

    Ante at 75 and n.26; see also ante at 81 n.32 (―[W]e rely on the principle
    that Harris and Tann could be found to have intended the reasonably foreseeable
    consequences of their acts.‖). The jury in this case, of course, was not required to
    make a finding that Foreman‘s intervention was reasonably foreseeable to Harris
    and Tann, let alone that the two defendants intended their actions to assist anyone.

    of them had he foreseen them) is not enough. Reasonable foreseeability is not the
    legal equivalent of intentionality; as this court explained in Wilson-Bey, to equate
    the two concepts is to confuse intentionality with the mental state on which mere
    negligence is based.17     Often enough, people do not intend the reasonably
    foreseeable consequences of their actions. While a trier of fact is permitted to infer
    that a defendant did intend the reasonably foreseeable consequences of his acts, a
    trier of fact is not and cannot be required to do so, and cannot be presumed to have
    done so.18
    My colleagues‘ theory of accomplice liability for the principal actor‘s
    reasonably foreseeable acts seems to be patterned on the doctrine of Pinkerton
    conspiracy liability. To establish Pinkerton liability, however, the government
    17

    ; see also, e.g., Robinson v. United
    States, 
    100 A.3d 95
    , 106 (D.C. 2014) (―Wilson-Bey rejected the proposition (and
    any jury instruction incorporating it) that a defendant may be held liable as an aider
    and abettor based on a merely negligent state of mind—i.e., for acts of
    confederates that were merely ‗reasonably foreseeable‘ to the defendant or the
    ‗natural and probable consequences‘ of the criminal venture in which the defendant
    intentionally participated—when a degree of mens rea higher than negligence was
    required to convict the principal actor for those acts.‖).

    442 U.S. 510

    person intends the ordinary consequences of his voluntary acts‖ held to
    unconstitutionally shift the burden of persuasion).
    222
    must prove ―that an agreement existed, that a substantive crime was committed by
    a co-conspirator in furtherance of that agreement, and that the substantive crime
    was a reasonably foreseeable consequence of the agreement between the
    conspirators.‖19 My colleagues‘ theory substitutes ―community of purpose‖ for the
    conspiratorial agreement that is the sine qua non of Pinkerton. But this is no small
    difference, because Pinkerton liability for the reasonably foreseeable acts of co-
    conspirators is based on the existence of an agency relationship between the
    conspirators. Such a relationship is created by their agreement but not by their
    mere ―community of purpose‖ as my colleagues use that term.20
    In essence, I think it fair to say that my colleagues‘ ―community of purpose‖
    theory of unintentional aiding and abetting is what this court warned against in
    Wilson-Bey: a hybrid that, without adequate justification, ―conflat[es] the two
    doctrines [of conspiracy and aiding and abetting] into one omnibus and sprawling
    theory of vicarious criminal liability.‖21 It is telling that the majority opinion cites
    the ―broader conspiracy to kill ‗outsiders‘ among the 22nd Street Crew members‖

    as constituting both the evidence of ―the community of purpose that, as a factual
    matter, was shared between Tann, Harris, and Foreman at the time of the
    shooting,‖ and the reason it was ―foreseeable to Harris and Tann that other 22nd
    Street Crew members in the area—including, unbeknownst to them, Foreman—
    would respond by joining in the effort to shoot Omar Harrison.‖22 The effect is to
    uphold Harris and Tann‘s convictions on a theory that they were Foreman‘s co-
    conspirators rather than a theory that they were his aiders and abettors. But the
    government has not relied on the doctrine of Pinkerton liability here. Harris and
    Tann were not charged with the Taylor/Mackey shootings under Pinkerton, and the
    government contended in the trial court that it ―was not required to show a prior
    association between Harris [or Tann] and the third shooter . . . . [as] [s]uch an
    association, while relevant under a vicarious-liability theory, was not, in the
    government‘s view, necessary for aiding and abetting.‖23 Perhaps the government
    misjudged its trial strategy, but if so, it is not the job of this court to remedy the
    government‘s mistake.

    In lieu of providing a sound rationale for their hybrid theory of aiding and
    abetting, my colleagues claim it is grounded in the common law. In support of that
    claim, they cite five cases.    None of them is from this jurisdiction, or from
    Maryland (whence our common law derives24), and none is from a court adhering
    to the Peoni doctrine. Four of the five cases were decided before Peoni, and the
    fifth was decided not under common law, but under a statutory amalgamation of
    aiding and abetting with conspiracy principles that has no counterpart in the law of
    our jurisdiction. None of the five cited cases approves the theory of aiding and
    abetting that my colleagues espouse; nor, I believe, would the courts in those cases
    find Harris and Tann liable as Foreman‘s accomplices on such a theory.
    In the two Kentucky cases, Whitt v. Commonwealth25 and Landrum v.
    Commonwealth,26 the appellate court held that the defendant could not be
    convicted of aiding and abetting a homicide in the absence of proof that he shared
    the intent or purpose of the principal, who had intervened, independently and
    without the defendant‘s knowledge, in the defendant‘s altercation with the

    decedent. My colleagues infer that the result would have been different had there
    been evidence that the principal and the putative aider and abettor shared the same
    purpose.27     That inference is belied, however, by the subsequent decision of
    Kentucky‘s highest court in Haynes v. Commonwealth.28
    The Haynes decision is rather on point. ―Upon receiving word that his two
    sons, the appellants John Robert and Tounsel [Ray] Haynes, were engaged in what
    might be called a ‗shoot-out‘ with William Caudill, the appellant Joe Haynes
    armed himself with a rifle, went to the scene of the affray, and shot and killed
    Caudill.‖29     All three appellants were convicted of manslaughter, and they
    appealed. With respect to the two sons, who were tried as aiders and abettors of
    their father‘s homicide, the Court of Appeals of Kentucky said ―[t]he question is,
    under what circumstances does a person engaged in an affray become an aider and

    But cf.

    abettor of another who intervenes uninvited, even assuming that they ‘share the
    criminal intent or purpose’‖?30
    Contrary to my colleagues‘ theory of aiding and abetting, the court reversed
    the two sons‘ convictions for lack of evidence that they sought their father‘s
    intervention or did anything to provide ―assistance or encouragement‖ to him,
    regardless of any shared criminal intent or purpose they and their father had in
    shooting at Caudill.31 Nothing in Haynes supports my colleagues‘ notion that the

    Whitt, 298 S.W. at 1103

    Id. Specifically, the
    court said,
    There is no evidence from which it may be reasonably
    inferred, as distinguished from speculation, that either
    of the sons sent for the father. There is no evidence
    even that John Robert knew he had arrived until after
    the killing. The clear weight of the evidence is that
    John Robert had stopped shooting before the father
    appeared and that Tounsel Ray never fired a shot
    during the entire proceeding. All that Tounsel Ray
    could have done that he did not do, as he lay in his
    place of protection behind a rock and saw his father‘s
    approach, was to ask him to stay back, but that
    omission would not itself amount to assistance or
    encouragement. Nor, of course, does the fact that
    Tounsel may have provoked the encounter. On
    balance, bearing in mind the great principle of
    (continued…)
    227
    outcome would have been different had there been evidence that Joe Haynes‘s
    intervention was foreseeable to his sons. On the contrary, there was such evidence
    in the case—as the court expressly acknowledged, Tounsel Haynes (who may have
    provoked the gun battle) saw his father coming to their aid and did not ask him to
    ―stay back‖—and the court held that it did not ―amount to assistance or
    encouragement.‖32
    The cases from New Mexico and Utah, State v. Ochoa33 and State v. Kukis,34
    likewise do not support the thesis that a defendant may be convicted as an aider
    and abettor without proof that he intentionally encouraged or assisted the principal.
    The two cases merely illustrate that a member of a criminal mob who intentionally
    helped other members commit a crime may be found guilty of aiding and abetting
    them even if he does not know which particular member of the mob actually

    perpetrated the offense.35 Neither Ochoa nor Kukis suggests that a defendant could
    be found guilty as an accomplice if he lacked the intent to aid or abet others in the
    mob to break the law.36 Rather, as the Supreme Court of New Mexico said in a
    subsequent case, ―a jury cannot convict a defendant on accessory liability for a
    crime unless the defendant intended the principal‘s acts.‖37
    Lastly, the Illinois intermediate appellate court‘s decision in People v.
    Cooks38 is similar to Ochoa and Kukis except that the defendant was a member of a
    criminal gang rather than a mob, and the case involves the application of a hybrid
    35
    That proposition does not apply to sustain the convictions of Harris and
    Tann in this case. They were not prosecuted for the offenses against Taylor and
    Mackey on the theory that they had intentionally encouraged or assisted an attack
    on Omar Harrison by a group (i.e., the 22nd Street Crew) that happened to include
    Foreman. Had such a theory been properly presented to the jury and resulted in
    conviction, my opinion on appeal might be different. See Rosemond v. United
    States, 
    134 S. Ct. 1240
    , 1245, 1248-50 (2014). But that is not the situation with
    which we are confronted.
    36
    It should be noted, however, that the Utah court accepted the doctrine,
    which we rejected in Wilson-Bey, of accomplice liability for criminal acts that are
    the ―probable and natural consequences‖ of the common design, even if those
    consequences were not part of the accomplice‘s original intent.

    state statute (rather than common law) providing, inter alia, that a person is
    ―legally accountable‖ for the conduct of another person in furtherance of their
    ―common criminal design or agreement.‖39 The defendant in Cooks was convicted
    under this provision for a murder committed by an unidentified gunman based on
    circumstantial evidence that the two were fellow gang members retaliating in a
    ―joint action‖ against members of a rival gang.40 Although the identity of the
    second gunman was not established at trial, nothing in the court‘s opinion suggests
    39
    Ill. Rev. Stat. 1985, ch. 38, par. 5-2(c), which provided that a person is
    ―legally accountable‖ for the conduct of another when
    (c) either before or during the commission of an offense, and with the
    intent to promote or facilitate that commission, he or she solicits, aids,
    abets, agrees, or attempts to aid that other person in the planning or
    commission of the offense.
    When 2 or more persons engage in a common criminal design or
    agreement, any acts in the furtherance of that common design
    committed by one party are considered to be the acts of all parties to
    the common design or agreement and all are equally responsible for
    the consequences of those further acts. Mere presence at the scene of a
    crime does not render a person accountable for an offense; a person's
    presence at the scene of a crime, however, may be considered with
    other circumstances by the trier of fact when determining
    accountability.
    The statute appears to combine conspiracy and aiding and abetting principles,
    including the natural and probable consequences doctrine that Wilson-Bey rejected.

    that the defendant‘s conviction would have been upheld absent evidence that he
    and the unknown gunman were acting together and in concert with each other. The
    Illinois Supreme Court has made clear that, even under the state‘s common design
    rule, a defendant must have ―the intent to promote or facilitate [the principal‘s]
    commission‖ of an offense.41
    In sum, I submit that my colleagues have crafted an unprecedented and
    unsound rationale for upholding Harris and Tann‘s convictions—a rationale that is
    irreconcilable with Wilson-Bey and other binding decisions of this court. I am
    compelled to add that this exercise in judicial creativity is all the more
    objectionable because it is done sua sponte and without the benefit of any briefing
    or other input by the parties on the merits of the ―community of
    purpose/foreseeability‖ theory of accomplice liability or its application in this case.
    I think it ill-advised, unfair to the parties, and contrary to this court‘s norms for the
    majority to develop and rely on this unforeseeable reshaping of a major doctrine in
    41
    People v. Perez, 
    725 N.E.2d 1258
    , 1266 (Ill. 2000). ―Accountability‖
    under Illinois law, the court explained, ―focuses on the degree of culpability of the
    offender and seeks to deter persons from intentionally aiding or encouraging the
    commission of offenses. Thus, unless the accomplice intends to aid the
    commission of a crime, no guilt will attach.‖

    (emphasis in the
    original; internal quotation marks and citation omitted).
    231
    the criminal law without affording the parties the opportunity to address it in
    supplemental briefing.42 In the past, when this court has considered deciding an
    appeal on a basis ―the parties failed to identify and brief‖—a discretionary
    departure from the general rule that points not urged on appeal are deemed to be
    waived—we have taken care to ―ensure procedural fairness, both to the
    government and to the defense, by providing each party with the opportunity to
    brief‖ the issue.43 This is so even when the issue injected by the court involves
    settled legal principles. There is no reason to deviate from that rule of basic
    fairness here.
    42
    By the same token, I think it unfair and inappropriate for the majority to
    find that the trial court‘s ―erroneous‖ failure to instruct the jury on the ―community
    of purpose‖ theory of liability was harmless without affording Harris and Tann an
    opportunity to address that question. (Parenthetically, for myself, I am not
    persuaded to find harmless the trial court‘s erroneous rulings and instructions
    rejecting the requirement that an accomplice must intend to encourage or assist the
    principal.)

    232
    For the foregoing reasons, I respectfully dissent from Section VII.C of the
    per curium opinion and would reverse the convictions of Harris and Tann arising
    from the shootings of Taylor and Mackey.
