    KING, Circuit Judge:
    The appellants in these consolidated proceedings, Mohammad
    Omar    Aly    Hassan,     Ziyad    Yaghi,        and   Hysen   Sherifi,    were     tried
    jointly in the Eastern District of North Carolina and convicted
    of   several      offenses    arising        from       terrorism   activities.        On
    appeal, the trio presents myriad challenges to their convictions
    and sentences.            As explained below, we reject the appellants’
    various contentions of error and affirm.
    I.
    A.
    On July 22, 2009, the federal grand jury in eastern North
    Carolina returned an indictment against the appellants and five
    others,       alleging     multiple      terrorism        conspiracies     and   related
    offenses.       Bench warrants were issued for all eight defendants
    on July 23, 2009, and, four days later, seven were arrested.                           In
    September 2009, a superseding indictment was returned, followed
    on     November     24,    2010,    by      the    operative     second     superseding
    indictment        (the    “Indictment”).            The    Indictment      alleged     the
    following       offenses     that     are    particularly        relevant     to     these
    appeals:
    •       Count One charged the eight defendants with
    conspiring to violate 18 U.S.C. § 2339A, that is,
    to provide material support and resources for
    violations of 18 U.S.C. § 956 (the “Count One
    conspiracy”);
    3
    •        Count Two charged the eight defendants with the
    conspiracy    offense  of  violating   18    U.S.C.
    § 956(a), i.e., to commit outside the United
    States   acts    that would   constitute    murder,
    kidnapping, and maiming if committed within the
    United States (the “Count Two conspiracy”);
    •            Counts    Four    and   Eight  charged   conspiracy
    ringleader     Daniel   Boyd  (“Boyd”),   his   son
    Zakariya,    and   appellant  Hysen  Sherifi   with
    possessing firearms in furtherance of a crime of
    violence — particularly, the Count Two conspiracy
    — in contravention of 18 U.S.C. § 924(c); and
    •            Count Eleven charged Boyd and Sherifi with
    conspiring to kill members of the uniformed
    services of the United States in attacks on
    military personnel and installations in Virginia
    and elsewhere, in violation of 18 U.S.C. § 1117
    (the “Count Eleven conspiracy”).
    None of the other charges in the Indictment were lodged
    against any of the appellants.                 Count Three charged Boyd with
    receiving a firearm and ammunition in interstate commerce, with
    knowledge that the offenses set forth in Counts One and Two
    would       be   committed   therewith,    in    contravention   of   18   U.S.C.
    § 924(b).         Counts Five, Nine, and Ten charged Boyd (and in Count
    Five,       Boyd’s   son   Dylan)   with   knowingly   selling   firearms    and
    ammunition to a felon, in violation of 18 U.S.C. §§ 922(d)(1)
    and 924.          Counts Six and Seven charged Boyd with making false
    statements to the government by misrepresenting his plans to
    meet others — including appellants Mohammad Omar Aly Hassan and
    Ziyad Yaghi — when Boyd travelled to the Middle East in 2007, in
    4
    contravention of 18 U.S.C. § 1001(a)(2).                      In Counts Twelve and
    Thirteen,         defendant   Anes     Subasic      was   charged      with    knowingly
    making      false       statements    to    procure    his    naturalization          as   a
    citizen, in violation of 18 U.S.C. § 1425(a).
    On February 9, 2011, Boyd pleaded guilty to the Count One
    and Count Two conspiracies, and, pursuant to his plea agreement
    with the government, Counts Three through Eleven were dismissed
    as to him.          Dylan and Zakariya Boyd each pleaded guilty to the
    Count       One    conspiracy,       and,    in   exchange,      the   other        charges
    against them were dismissed.                 Boyd was sentenced to 216 months
    in prison, and his sons Dylan and Zakariya were sentenced to 84
    months       and    93     months,     respectively.            Subasic       was    tried
    separately from the appellants, convicted of the four offenses
    alleged against him, and sentenced to 360 months.                             As for the
    appellants, Hassan was convicted of the Count One conspiracy and
    sentenced to 180 months; Yaghi was convicted of the Count One
    and   Count       Two    conspiracies       and   sentenced     to   380   months;       and
    Sherifi was convicted of the Count One, Count Two, and Count
    Eleven      conspiracies,      plus     Counts     Four   and    Eight,    and      he   was
    sentenced to 540 months. 1
    1
    Although seven of the eight defendants were apprehended
    and successfully prosecuted, the eighth, Jude Kenan Mohammad,
    apparently remains at large.  Mohammad was charged solely with
    the Count One and Count Two conspiracies. Other than Mohammad,
    each of the defendants was convicted of the Count One

    B.
    The      parties       and        the    trial    court       were      in    substantial
    agreement on the essential elements of the offenses tried before
    the jury. 2    First, to obtain a conviction under 18 U.S.C. § 2339A
    for the Count One conspiracy, the government was required to
    prove    as   to     each    appellant:              (1)    that       he    entered   into       a
    conspiracy;     (2)     that      the        objective     of    the    conspiracy        was    to
    provide material support or resources; and (3) that he then knew
    and intended       that     the        provision      of   such     material       support       or
    resources would be used in preparation for, or in carrying out,
    a violation of 18 U.S.C. § 956.                       See United States v. Chandia,
    
    675 F.3d 329
    , 332 n.1 (4th Cir. 2012).                            “[M]aterial support or
    resources,”     as    used        in    § 2339A,      includes         currency     and    other
    property,     training,        weapons,         expert     advice       or    assistance        and
    personnel.         See      § 2339A(b)(1).                 To    prove       the   Count        Two
    conspiracy alleged under 18 U.S.C. § 956(a), the government was
    obliged to show as to each appellant:                           (1) that he entered into
    conspiracy. Boyd, Yaghi, Sherifi, and Subasic were convicted of
    the Count Two conspiracy. Hassan was acquitted of the Count Two
    conspiracy, and that charge was dismissed as to Zakariya and
    Dylan Boyd.
    2
    At trial, there was debate over whether Count One
    required, as an essential element of the offense, the commission
    of an overt act.    The trial court ruled that no overt act was
    necessary.   On appeal, the appellants have abandoned any issue
    in that regard.
    6
    a conspiracy; (2) knowing and intending that the objective of
    the conspiracy was murder, kidnapping, or maiming outside the
    United States; (3) that the conspiracy was entered into within
    the United States; and (4) that a conspirator, not necessarily a
    defendant or an appellant, committed an overt act in furtherance
    of the conspiracy within the jurisdiction of the United States. 3
    The Indictment identified the purposes and objects of the
    Count One and Count Two conspiracies, which were generally to
    advance   violent   jihad,   support   and   participate   in    terrorist
    activities outside the United States, and commit acts of murder,
    kidnapping, and maiming outside the United States.              The manner
    3
    Section 2339A of Title 18 criminalizes “provid[ing]
    material support or resources . . . knowing or intending that
    they are to be used in preparation for, or in carrying out, a
    violation of [certain enumerated statutes].”       18 U.S.C.
    § 2339A(a).     Importantly, one of the statutes listed in
    § 2339A(a) is 18 U.S.C. § 956.      Section 956 provides, in
    pertinent part, that
    [w]hoever, within the jurisdiction of the United
    States, conspires with one or more other persons,
    regardless of where such other person or persons are
    located, to commit at any place outside the United
    States an act that would constitute the offense of
    murder, kidnapping, or maiming if committed in the
    . . . United States shall, if any of the conspirators
    commits an act within the jurisdiction of the United
    States to effect any object of the conspiracy, [be
    guilty of an offense against the United States].
    18 U.S.C. § 956(a)(1).   The appellants have not challenged the
    grand jury’s decision to charge the Count One and Count Two
    conspiracies as separate offenses.     As a result, we need not
    examine whether Counts One and Two were merged for any purpose.
    7
    and   means    by   which   the     conspiratorial      objects     were    to   be
    accomplished by the defendants and their conspirators included
    the following:
    •      To   prepare   to become  “mujahideen”  and  die
    “shahid” — that is, as martyrs in furtherance of
    violent jihad;
    •      To radicalize others, mostly young Muslims or
    converts to Islam, to believe in “fard’ayn,” the
    idea that violent jihad is a personal obligation
    on the part of every good Muslim;
    •      To offer financing and training in weapons, and
    to assist in arranging overseas travel and
    contacts so that others could wage violent jihad;
    •      To raise money to support efforts in training and
    equipping   personnel,   and   to   disguise    the
    destination of such monies from the donors; and
    •      To obtain assault weapons such as the AK-47, and
    to develop familiarity and skills with the
    weapons   of   choice   used by   mujahideen  in
    Afghanistan and elsewhere.
    Multiple      overt   acts    were      specifically    alleged      in    the
    Indictment     that    relate      to   the     Count   One   and    Count       Two
    conspiracies, including, inter alia:
    •   In late 2006, Yaghi travelled to Jordan to engage
    in violent jihad;
    •   In late 2006, Boyd purchased a Bushmaster carbine
    rifle and magazine;
    •   In early 2007, Boyd purchased a Ruger mini 14
    long gun;
    •   In early 2007, Boyd purchased airline tickets to
    Israel from the United States for himself and his
    sons;
    8
    •    In early 2007, plane tickets were purchased for
    Yaghi and Hassan to travel from the United States
    to Israel;
    •    In June 2007, Boyd, his son Zakariya, Yaghi, and
    Hassan departed Raleigh, North Carolina, for
    Israel.    Having failed in their attempts to
    engage in violent jihad, the four men returned to
    the United States in late July 2007;
    •    Upon his arrival back in the United States, Boyd
    lied to federal agents by denying that he had
    intended to meet Hassan and Yaghi in Israel;
    •    In February 2008, Boyd solicited money to fund
    the travel of “brothers” overseas to engage in
    violent jihad;
    •    In June 2008, Boyd accepted $500 in cash from
    Sherifi to help fund violent jihad;
    •    In June 2008, Boyd showed Sherifi how to use a
    Kalashnikov AK-47;
    •    In June 2008, Sherifi departed North Carolina for
    Kosovo to engage in violent jihad;
    •    In November 2008, Boyd purchased a Mossburg
    rifle, a .357 revolver, and a Century Arms rifle;
    •    In early 2009, Boyd purchased an Ishmash SAGA
    .308 rifle, three Century Arms rifles, a Ruger
    5.56 rifle, and a Smith & Wesson .223 rifle;
    •    In April 2009, Sherifi returned from Kosovo to
    the United States for the purpose of soliciting
    funds and personnel to support the mujahideen;
    and
    •    In June and July 2009, Boyd, Sherifi, and
    Zakariya Boyd trained in military tactics and the
    use of weapons in Caswell County, North Carolina.
    With respect to the essential elements of Counts Four and
    Eight — which were tried against Sherifi alone — the government
    9
    was required to establish:                    (1) that Sherifi knowingly possessed
    a firearm on or about June 10, 2009, and again on or about July
    7, 2009; and (2) that he did so to further the crime of violence
    alleged in Count Two.                   See 18 U.S.C. § 924(c). 4            Those charges
    arose from the weapons training sessions conducted by Boyd and
    others in 2009 in Caswell County.
    Finally,       to    secure      Sherifi’s      conviction        under   18    U.S.C.
    § 1117        on     the    Count      Eleven     conspiracy,       the    government        was
    required        to    demonstrate:              (1)   that   Sherifi      entered      into    a
    conspiracy; (2) the object thereof was to kill or attempt to
    kill        officers       and    employees      of   the    executive     branch      of    the
    federal government (here, members of the uniformed services), on
    account of — or while such officers and employees were engaged
    in — the performance of their official duties; and (3) that at
    least        one     overt       act    was     committed     in    furtherance        of    the
    conspiracy. 5              Count       Eleven    identified        several    overt         acts,
    4
    Pursuant to 18 U.S.C. § 924(c), a “crime of violence” is a
    felony offense that, “by its nature, involves a substantial risk
    that physical force against the person or property of another
    may be used in the course of committing the offense.”     Section
    956(a) of Title 18 — the Count Two conspiracy statute — falls
    within that definition.
    5
    Section 1117 of Title 18 provides, in pertinent part, that
    “[i]f two or more persons conspire to violate [certain sections]
    of this title, and one or more of such persons do any overt act
    to effect the object of the conspiracy, each shall be [guilty of
    an offense against the United States].”    Section 1114 is among
    the enumerated sections, and makes it a crime to “kill[] or
    (Continued)
    10
    including the following:         In June 2009, Sherifi’s coconspirator
    Boyd conducted reconnaissance at the Quantico, Virginia Marine
    Corps Base; also in June 2009, Boyd reviewed maps of Quantico,
    intending the maps to be used to plan and coordinate an attack
    on   the   base;   and,   in   July    2009,   Boyd   possessed    weapons   and
    ammunition that would be used at Quantico, asserting that they
    were for the base and to attack Americans.
    C.
    During the post-Indictment period leading to the trial, the
    appellants    filed    multiple       pretrial   motions   in     the   district
    court, several of which sought to curtail the government’s case.
    For example, the appellants challenged the government’s expert
    witness and moved to exclude evidence obtained pursuant to the
    Foreign Intelligence Surveillance Act (“FISA”).                   The district
    court disposed of some of the appellants’ evidentiary challenges
    prior to trial.       First, after conducting a Daubert hearing, the
    court authorized the trial testimony of the government’s expert,
    Evan Kohlmann, subject to specified limitations.                See Daubert v.
    Merrell Dow Pharm., Inc., 
    509 U.S. 579
    (1993).                     Second, the
    court considered and rejected the appellants’ challenges to the
    attempt[] to kill any officer or employee of the United States
    . . . while such officer or employee is engaged in or on account
    of the performance of official duties.” 18 U.S.C. § 1114.
    11
    government’s      FISA-derived       evidence.        After    conducting     an    in
    camera and       ex   parte    review   of      relevant   materials,   the    court
    ruled that such evidence was admissible.                      Finally, the court
    considered several other evidentiary challenges, holding some of
    them in abeyance pending the trial proceedings.
    Before      trial,       the    prosecution      moved    to   preclude       the
    appellants from arguing to the jury that their alleged unlawful
    conduct    was   protected      by   the   First    Amendment.      Although       the
    trial court agreed with the government “that there is no First
    Amendment defense to the crimes with which [the appellants] are
    charged,” the court determined “that granting the government’s
    motion would go too far.”             See United States v. Boyd, No. 5:09-
    cr-00216, slip op. at 8-9 (E.D.N.C. July 12, 2011), ECF No.
    1222.     The court further explained:
    While the government correctly points out that the
    First Amendment provides no constitutional right to
    actively support violent crime, the wording of the
    government’s motion would suggest that defendants
    should not be allowed to mention the First Amendment
    at all at trial, a restriction that strikes the court
    as inappropriate.     As defendants note, it is the
    government’s burden at trial to prove that defendants
    engaged in unlawful conduct.      Based on defendants’
    briefs, it seems that defendants intend to challenge
    exactly what “conduct” the government contends is
    unlawful.   This is a permissible argument to make.
    However, in making opening and closing arguments and
    in questioning witnesses, defendants may not invite
    jury nullification by suggesting that the First
    Amendment is a defense to the crimes charged.     Both
    sides may submit proposed jury instructions regarding
    the First Amendment, and such proposals will be
    considered by the court at the appropriate time.

    II.
    During the trial itself — which was conducted in New Bern
    over a three-week period in September and October of 2011 — the
    government presented approximately forty witnesses.                     Of those,
    about twenty-two were law enforcement officers, including FBI
    agents   and   employees.       Other    prosecution        witnesses    included
    expert     Kohlmann,     three      informants,            and   three      named
    coconspirators (Boyd and his sons Dylan and Zakariya), as well
    as former friends and associates of the defendants. 6                     Of the
    three appellants, only Sherifi presented evidence.                     During his
    trial presentation,      Sherifi   called         three   witnesses,    including
    himself.
    A.
    Our description of the trial evidence is provided in the
    light most favorable to the government.                   See United States v.
    Burgos, 
    94 F.3d 849
    , 862-63 (4th Cir. 1996) (en banc).                       That
    evidence   established      a   series       of    conspiratorial      activities

    During the course of the terrorism investigation resulting
    in the Indictment and prosecution, the government collected the
    FISA-derived evidence, as well as other audio recordings, such
    as those made by informants wearing recording devices.        The
    prosecution used computer records and a number of those
    recordings in evidence plus materials seized from social media
    and other internet sites.

    centering on Boyd, who, after pleading guilty to two of eleven
    charges, became the prosecution’s chief trial witness.
    1.
    A citizen of the United States who converted to Islam as a
    child, Boyd had, as a young adult, spent time in Pakistan and
    Afghanistan in the 1980s and early 1990s.                 While living abroad,
    Boyd participated in the Afghan resistance against the Soviet
    occupation    and   received        the     nickname    “Saifulla,”    which,      in
    Arabic, means “Sword of God.”                Boyd later learned that he had
    been in a training camp operated or funded by the notorious al-
    Qaida    leader   Osama    bin     Laden.       Boyd   returned   to   the    United
    States in the early 1990s, and, after another trip to Pakistan,
    settled with his family near Raleigh.
    Boyd     thereafter         grew   increasingly      radicalized        in   his
    religious    beliefs      and,    by    2004,   began   to   espouse   a     violent
    ideology, including the view that the killing of non-Muslims was
    a “fard,” or “fard’ayn,” that is, a religious obligation imposed
    by Islam.     As Boyd became more extreme, he disassociated himself
    from the Islamic community in the Raleigh area.                   Boyd then began
    to meet and discuss his violent religious views with others at
    his Raleigh home and at the Blackstone Halal Market, a grocery
    store he owned and operated for about a year in nearby Garner.
    The appellants met and talked with Boyd on numerous occasions
    during the course of the conspiratorial activities, during which
    14
    they often discussed violent jihad.                           Boyd explained that, to
    him, jihad required “doing something to fulfill [his] obligation
    in    Islam,”      and     was    “suggestive          of    [men]    actually         involving
    [themselves]            with     going     and        physically      helping       with       the
    resistance         or     fighting       against        . . .       the    NATO    forces       in
    Afghanistan or Iraq, or anyplace, really.”                          J.A. 1549. 7       Boyd and
    the appellants “were at a point of agreement or a meeting of the
    minds” as to this ideology and understanding of violent jihad.
    
    Id. at 1549-50.
    2.
    a.
    About 2005, the FBI initiated a criminal investigation into
    Boyd’s      activities.           By    mid-2006,       the   FBI     had    introduced        its
    first       informant,            Abdullah           Eddarkoui,           into     the        Boyd
    investigation.            In that capacity, Eddarkoui grew close to Boyd
    and   his    family,       eventually         interacting       with       Boyd   on    a    daily
    basis.        In    2007,      the      FBI    introduced       a    second       confidential
    informant,         Alvin       Harris,        into     its    investigation.                Harris
    obtained      a    job     with        another       Boyd    business,       a    construction
    company called Saxum Walls.                      Like informant Eddarkoui, Harris
    became a close friend of the Boyd family.                                  Harris generally
    7
    Citations herein to “J.A. ___” refer to the contents of
    the Joint Appendix filed by the parties in these appeals.
    15
    spent several days a week with Boyd.                    Boyd eventually helped
    Harris obtain a passport so that Harris could travel abroad to
    engage in violent jihad.
    Appellant Yaghi met Boyd in 2006 when Yaghi, then eighteen
    years old, approached Boyd at an Islamic center in Durham.                       The
    two men initially spoke about Boyd’s experiences in Afghanistan,
    after which Yaghi obtained Boyd’s phone number.                   That same year,
    the    FBI   also   opened     an   investigation      into     Yaghi,   which   was
    eventually merged into the Boyd investigation.
    In the months that followed their first meeting in 2006,
    Boyd and Yaghi had several conversations, primarily at Islamic
    centers      in   the    Raleigh    area   and   in    Boyd’s    home.     The   men
    discussed various topics, including Boyd’s experiences overseas,
    plus his views on Islam and violent jihad.                      Yaghi also sought
    Boyd’s advice about Jordan, because Yaghi wanted to travel in
    that    country     to    visit     relatives    and    study     Islam.     Yaghi
    explicitly asked Boyd where in Jordan he would find the “best
    brothers.”        J.A. 1548.       This inquiry referred to Muslim men who
    were “going to pray” and maintain “the bonds of fellowship and
    Islam,” and those who “understood [the] obligation of jihad” and
    could help Yaghi “gain access” to violent resistance movements.
    
    Id. at 1550-51.
             In response, Boyd told Yaghi about a mosque in
    Jordan where he could find the “best brothers.”
    16
    In October 2006, Yaghi travelled to Jordan.            Shortly before
    Yaghi left the United States, Boyd and several others — who
    understood and shared Boyd’s violent and extremist ideology —
    met in a parking lot outside a Durham Islamic center to wish
    Yaghi well.     Boyd described this as a “joyous send-off,” during
    which Boyd and the others gave Yaghi gifts, including an Afghan
    blanket and a “traditional Pashtun hat.”           J.A. 1561-62.      The men
    wished Yaghi well, sending him off with the valediction “may we
    meet   again   in   heaven,”    which   conveyed   their   hope   that   Yaghi
    would make his way to the battlefield, and, if he died, find his
    way to heaven.      
    Id. at 1555,
    1562.        According to Boyd, the terms
    “battlefield” and “battlefront” were used to refer to locations
    where Muslims were then actively waging violent jihad against
    the    “kuffar,”    including    wars    in   Afghanistan,    Iraq,   Kosovo,
    Chechnya, Somalia, Palestine, and Kashmir.             As Boyd and others
    explained to the jury, “kuffar” is a derogatory term, commonly
    used by violent Muslims to refer to non-Muslims.                  See 
    id. at 989-90,
    1399-1400, 1557.        Boyd and his coconspirators shared the
    view   that    getting   to    the   jihadist   battlefield    and    fighting
    against the kuffar was a necessary and laudable aspiration.
    While in Jordan in 2006, Yaghi remained in touch with Boyd
    by phone and email.       In November 2006, Yaghi sent Boyd an email
    explaining that it was “getting more and more obvious that the
    true believer[s]” of Islam — such as Yaghi and Boyd — were
    17
    “under attack by the kuffar and by ‘muslims.’”                      J.A. 4000.     As
    Boyd explained, Yaghi’s reference to “muslims” in that email
    meant    those   who    claimed    to    be    believers      but    who   were   not
    actually “true believers.”              
    Id. at 1556-57.
            Boyd recalled a
    “shared understanding amongst a lot of the rhetoric online and
    some of the people in the community” that those who shared his
    beliefs were “under attack . . . physically in the different
    battlefields,” as well as “under attack ideologically from the
    . . .    naysayers     of   our   religion,”     who    did    not    believe     that
    Muslims    had   an    obligation    to    defend      those   fighting      on   the
    jihadist battlefields.        
    Id. at 1557.
    Prior to his departure for Jordan, Yaghi told Boyd that he
    hoped to find a wife overseas.                While abroad, Yaghi wrote Boyd
    that Yaghi was waiting to see how his “marriage” would go before
    planning to “make [his] next move,” concluding by advising Boyd
    that they would “meet in a far better place than this earth.”
    J.A. 4000.       It was understood by Boyd and his associates that
    the phrases “getting married” and “finding a wife” were code for
    seeking to reach the battlefield to engage in violent jihad.
    
    Id. at 1592.
    8        During some of their exchanges while Yaghi was
    8
    Kohlmann, the prosecution’s expert, explained to the jury
    that speaking in a coded manner is common in jihadist cells:
    “Frequently, in communications, individuals will talk about
    getting married as a euphemism for engaging in a violent
    extremist act, often a suicidal act, the idea being that you
    (Continued)
    18
    abroad,    Boyd     recalled    Yaghi     seeming      “frustrated”        that    Boyd
    “wasn’t able to fulfill any real helpful role for [Yaghi] to,
    you know, get inside somewhere to a battlefield.”                     
    Id. at 1560-
    61.
    While    in    the   Middle     East     in    2006,    Yaghi   also        posted
    numerous      statements       and   copious         information      on     Facebook
    concerning     his    adherence      to   the       violent   jihadist      ideology.
    Yaghi consistently praised the teachings of Anwar al-Awlaki, an
    imam and cleric who was born in the United States and later
    became an al-Qaida militant in Yemen.                  Al-Awlaki was well known
    as an al-Qaida leader who espoused violent and radical jihadist
    views. 9   While overseas, Yaghi also kept in touch with appellant
    will be married to the virgins of paradise after the act is
    completed.” J.A. 379.
    9
    Al-Awlaki grew to prominence in the United States during
    the late 1990s as a cleric and activist.           Following the
    September 11, 2001 terrorist attacks, al-Awlaki came under
    suspicion for his associations with two of the 9/11 hijackers.
    Al-Awlaki was thereafter linked to other terrorist activities
    within   the   United  States,   often  communicating   with   the
    perpetrators via email.       In 2003, al-Awlaki departed this
    country for Yemen and never returned, eventually becoming an
    active high-ranking member of al-Qaida. Al-Awlaki published his
    extreme views — particularly that violent jihad against America
    was a binding obligation on Muslims — through speeches and
    writings, which were widely disseminated on the internet.       As
    Kohlmann    explained,   al-Awlaki’s   teachings   “have    proven
    extraordinarily popular among extremists living in western
    countries,” and have “regularly surfaced” in cases of “homegrown
    terrorists.”    J.A. 299.   In 2011, al-Awlaki was killed by a
    drone strike in Yemen.

    Hassan, who had been his good friend for some time.                    Yaghi and
    Hassan corresponded with one another largely through Facebook.
    In   their    Facebook     postings,    Hassan    and    Yaghi    discussed   the
    teachings     of     al-Awlaki   and   posted   rap    songs   and   poems   about
    their animosity towards the non-Muslim kuffar.                   One of Yaghi’s
    Facebook postings included the following:
    [F]eds tryed ta get at me but im quick wit the
    trickery thas how I stay slippery / kuffar get smoked
    like hickory / dickery dock i pull the glock so fast
    the clock dont have chance ta tock / or tick let the
    shots rip then I stop the shit / pop my wrists I don’t
    give uck if cops exist / im above the law already
    explained how im quick on the draw / heard the battle
    in fallujahs ferocious / niggas runnin out of ammo but
    they stay strapped wit explosives / rpg 7s I aint
    worried if all them niggas die cuz inshallah they all
    going ta heaven[.]
    J.A. 4395.         Hassan also posted violent rhymes, including the
    following:
    I used to smoke tree / but I dont do that shit no more
    that shits far / only thing I smoke now is fuckin
    kuffar / getting high off their deaths / fuck buryin
    them, let the animals eat their flesh / leave their
    bones for weapons or for conditioning my shins[.]
    
    Id. at 4388.
             Hassan and Yaghi actively promoted the violent
    views and teachings of al-Awlaki by providing literature and
    videos to others, both within and outside the conspiracies.
    In     2007,    after   Yaghi    returned   to    North     Carolina    from
    Jordan, he continued his friendship with Boyd.                   The two men met
    on a substantial number of occasions throughout 2007.                        Yaghi
    also introduced Hassan to Boyd and accompanied Hassan to Boyd’s
    20
    home at least twice. 10        During their visits with Boyd, the three
    men discussed the “obligation of jihad,” which Boyd explained as
    the need “to go and actually defend against the specific wars in
    Iraq and Afghanistan that were taking place,” and to fight in
    other wars that were “going on in the Muslim world,” such as in
    Chechnya and Palestine.          J.A. 1653-64.
    b.
    In   February    2007,    Yaghi     learned   that   Boyd    would     be
    travelling to Israel and Palestine with his sons.                   Yaghi asked
    to accompany Boyd to the Middle East and asked if Hassan could
    join them as well.        Because the Boyds were taking a family trip,
    Boyd told Yaghi that he and Hassan could not travel with the
    Boyds.        Boyd   agreed,   however,   to   facilitate    the   purchase    of
    plane tickets for Yaghi and Hassan to fly to Israel.                  Yaghi and
    Hassan then gave Boyd money for their tickets, and Boyd arranged
    through a travel agency for a wire transfer of the necessary
    funds.       Boyd believed that Hassan and Yaghi wanted to travel
    overseas in an effort to “get to a battlefront somewhere.”                   J.A.
    1587.        Boyd also told informant Eddarkoui that he had asked
    Yaghi and another boy (whom Boyd did not specifically identify)
    to “go somewhere overseas for jihad.”                 
    Id. at 780.
          In the
    10
    Although Hassan had been “peripherally known to the Boyd
    family during his teenage years,” J.A. 3071, Hassan did not meet
    Boyd until 2007, when Hassan was approximately twenty years old.
    21
    months leading to their June 2007 trip, Hassan and Yaghi sought
    Boyd’s   advice    about    travelling      in   Israel    and    Palestine,   and
    about the locations they should visit.                 Hassan and Yaghi also
    told Boyd that they hoped “to get married” and find wives while
    they sojourned in the Middle East.           
    Id. at 1571.
    Hassan and Yaghi discussed being familiar with firearms and
    assault weapons, as well as the need for training in their use,
    both with one another and with Boyd.               Hassan and Yaghi knew that
    Boyd maintained a large stockpile of such weapons.                        Boyd had
    built    his   weapons     arsenal   over    the    years,   and     it   included
    numerous assault rifles and handguns.                The Boyd sons were also
    familiar with such weapons.          Prior to 2006, for example, Dylan
    Boyd showed an AK-47 to a high school friend.                    Hassan and Yaghi
    discussed the need to obtain such weapons to use in implementing
    their beliefs in violent jihad.             In early 2007, Hassan wrote on
    Yaghi’s Facebook page, “[Y]o, theres an AK in Garner for sale —
    only 250 dollar . . . us 3 could get it for real.”                    J.A. 4383.
    Hassan also posted a link to a YouTube video concerning the
    basics   of    shooting    and   marksmanship.        In   March    2007,   Hassan
    purchased a small caliber rifle from a sporting goods store in
    North Carolina.       Several months later, Hassan and Yaghi gave
    Boyd a car ride from a mosque in Durham where the three men had
    been attending religious services.               During the ride, Hassan and
    22
    Yaghi    showed    Boyd   the    small   rifle,       explaining    that   they    had
    purchased it for “training” and “target practice.”                   
    Id. at 1796.
    c.
    Boyd and his son Zakariya departed for Israel on June 12,
    2007, and Hassan and Yaghi left the very next day.                         Boyd and
    Zakariya    were    denied      entry    into    Israel,      however,     and    they
    instead went to Jordan via France.                    The Boyds toured Jordan,
    staying with a friend, and they concluded their Jordanian trip
    in the town of Salt, where they were joined by Dylan Boyd.                        Like
    the Boyds, Yaghi and Hassan were denied entry into Israel; they
    instead detoured to Jordan via Germany.
    While abroad, Hassan and Yaghi repeatedly sought to contact
    Boyd by email and telephone.              They received no responses from
    Boyd, however, notwithstanding that Boyd had email access during
    his travels.       Hassan and Yaghi also attempted to reach Boyd by
    calling his home in North Carolina, but they were unable to make
    contact.     Boyd    later      told    the   FBI     that,   as   the   trips    were
    originally planned, he was to meet Hassan and Yaghi when they
    arrived in Israel and “hook them up” with persons who would
    assist    their    travels      in   Israel     and    Palestine.        J.A.    1584.
    Hassan and Yaghi were to “go on their way from there,” 
    id., that is,
    they would ultimately find their way to the battlefield and
    participate in violent jihad.
    23
    While      the    four    men     were    travelling          in    the    Middle    East,
    rumors circulated in Raleigh that Boyd had sent Hassan and Yaghi
    overseas to go to the battlefield — specifically to engage in
    violent jihad.          Boyd learned that Aly Hassan, Hassan’s father in
    North Carolina, was upset by those rumors.                                 Boyd called the
    senior     Hassan       from    Jordan,        and    the     two        men    had   a   heated
    discussion about the younger Hassan’s travel plans.                                   Boyd told
    the senior Hassan that Boyd was not in touch with either Hassan
    or Yaghi, and he could not get a message to them.
    d.
    After Boyd and his sons, on the one hand, and Hassan and
    Yaghi,     on    the    other,    returned       from       their    2007       trips     to   the
    Middle East, Hassan and Yaghi remained close friends.                                      Their
    contacts with Boyd, however, diminished substantially.                                    Hassan
    and Yaghi neither emailed nor phoned Boyd, but they visited him
    at   the    Blackstone         Halal    Market       in     Garner        on    at    least    two
    occasions, in the fall of 2007 and again in the spring of 2008.
    During one of those visits, Yaghi introduced Boyd to defendant
    Jude Kenan Mohammad.
    Mohammad had been raised in the United States, though his
    father     was    from       Pakistan    and    still       lived        there.        Boyd    and
    Mohammad became good friends, often discussing such matters as
    Boyd’s experiences fighting in Afghanistan, Mohammad’s relatives
    in   Pakistan,         and   their     shared       radical    and        violent     religious
    24
    views.     Mohammad also spoke of the evils of westernized living.
    In the fall of 2008, Mohammad talked of travelling to Pakistan
    to   “go   back    with      his    people,”       which     Boyd    “assumed      was    to
    eventually      try    to    get    to     the    battlefield.”           J.A.    1605-06.
    Mohammad also stayed at the Boyd home when the Boyds were on
    vacation.         While      in    Boyd’s    home,     Mohammad       reviewed      Boyd’s
    materials    on       violent      jihad    and     extremist       Islamic      ideology.
    Mohammad    passed      along       some    of     those   jihadist       materials       to
    others, including Yaghi.              His mother recalled dramatic changes
    in Mohammad’s behavior during 2008, after he began to espouse
    Boyd’s violent jihadist ideology.                     In October 2008, Mohammad
    went to Pakistan.            Following his departure, Mohammad’s mother
    confronted Yaghi — who had moved into Mohammad’s apartment —
    about the changes in her son.                    Yaghi advised her that Mohammad
    was “in the same place” that Yaghi had been “a year prior.”                               
    Id. at 1904-05.
            Boyd   explained       that    being    in    the    “same    place”
    metaphorically referred to Mohammad having the understanding and
    beliefs that Yaghi espoused with respect to violent jihad.                                
    Id. at 1744.
    e.
    Aside from the aforementioned encounters at the Blackstone
    Halal    Market,      Boyd    had   little       contact   with     either       Hassan    or
    Yaghi after their return from the 2007 trip to the Middle East.
    In January 2009, Yaghi and Hassan were arrested on unrelated
    25
    charges. 11      While detained, Hassan asked his then paramour to
    email       al-Awlaki    directly       to    seek   advice      on   Hassan’s       behalf.
    Hassan also asked her to remove from Facebook some of Hassan’s
    postings, messages, and videos, specifically those relating to
    violent jihad.          In March 2009, Boyd contacted Yaghi, seeking to
    ascertain what, if anything, Yaghi may have discussed with law
    enforcement       officers       while        he   was     in    custody.        In    that
    conversation with Boyd, Yaghi denied being a snitch.                            Otherwise,
    Hassan and Yaghi failed to keep in touch with Boyd, and the
    government has conceded that they were not part of Boyd’s inner
    circle after late 2007.
    Although       the    defense     lawyers     for    both      Hassan    and    Yaghi
    emphasized       their       clients’    termination        of   communications            with
    Boyd, the evidence — viewed in the proper light — established a
    “parallel set of initiatives” that the prosecution proved were
    being carried on by Hassan and Yaghi in 2008 and 2009.                                     See
    United       States     v.    Boyd,     No.    5:09-cr-00216,         slip     op.    at    19
    (E.D.N.C. Oct. 10, 2011), ECF No. 1494 (“Sufficiency Opinion
    I”).     As the district court explained, after his return from the
    2007 trip to the Middle East, Yaghi gave a speech at the Islamic
    11
    According to court records, Hassan, Yaghi, and another
    man were charged with kidnapping and restraining a student at
    North Carolina State University during a robbery.       Hassan
    pleaded guilty to false imprisonment, and Yaghi pleaded guilty
    to felonious restraint.
    26
    Association     of        Raleigh    promoting       jihad       and    the   corresponding
    moral obligation to commit violence against non-Muslims.                                Hassan
    and Yaghi regularly communicated with one another through email
    and Facebook about jihadist ideology and continued to discuss
    and engage in weapons training.                      Hassan espoused increasingly
    violent   and    extremist          jihadist       views    during       that     period,   as
    demonstrated         by     his     Facebook       postings.            The     trial    court
    emphasized that Hassan was highly proficient in using technology
    to disseminate his beliefs and in seeking to recruit others to
    his   violent    ideology.            See    
    id. at 25.
        Hassan       also    became
    progressively fervent in his support of al-Awlaki.
    Hassan befriended an individual named Jamar Carter in late
    2006 or early 2007, first meeting Carter at a UPS store where
    Carter worked near Raleigh.                 Hassan and Yaghi introduced Carter
    to the Islamic religion, and shared with Carter their beliefs in
    violent jihad and appreciation for the teachings of al-Awlaki.
    At one point, Hassan showed Carter videos depicting car bombings
    and   expressed       his     view    that     such      actions       were     permissible.
    Carter,   having           decided     that        his     views       of     Islam     varied
    dramatically from those of Hassan and Yaghi, eventually ceased
    associating with them.
    Boyd’s lack of contact with Hassan and Yaghi after 2007 was
    attributed      by    the     prosecution       to       several       factors,    including
    Boyd’s concern that Hassan and Yaghi talked too much and drew
    27
    unwanted attention to Boyd and his family.                     As the trial court
    observed, Boyd was questioned by FBI agents twice in the summer
    of 2007, once in July and again in August, and Boyd thus grew
    ever more concerned that he was under FBI surveillance.                            See
    Sufficiency Opinion I at 18.           During his meetings with the FBI,
    the agents asked Boyd about his travels abroad and his contacts
    with    Hassan    and    Yaghi.     Boyd    misled     the     FBI    concerning   the
    extent of his contacts with Hassan and Yaghi, initially failing
    to reveal that he had planned to meet Hassan and Yaghi in 2007
    while they were travelling abroad in the Middle East.
    3.
    a.
    In March 2008, a mutual friend introduced Boyd to appellant
    Sherifi, who was then about twenty-three years old.                      Sherifi and
    Boyd    became    close     friends,    and       Sherifi      often    visited    the
    Blackstone Halal Market where he and Boyd discussed their shared
    views advocating a violent jihadist ideology. 12                     Boyd and Sherifi
    believed that dying “shahid” — as a martyr — was an important
    goal    for   a   good    Muslim.      In       the   spring    of     2008,   Sherifi
    introduced Boyd to defendant Subasic.
    12
    The Blackstone Halal Market closed in approximately mid-
    2008.   Thereafter, several of the coconspirators met regularly
    in Boyd’s home.
    28
    Sherifi, Boyd, Dylan, and Zakariya made regular efforts to
    raise money to support jihadist causes — that is, to fund their
    own travels or to send money to other “brothers” to further
    violent jihadist efforts overseas.           In June of 2008, Sherifi
    gave Boyd $500 cash for the “sake of Allah.”             J.A. 1657.     Boyd
    explained “that this money was to be used to either help get
    somebody over there to the battlefield or get it to the people
    who   were   already   there   fighting.”     
    Id. On July
      21,   2009,
    shortly before his arrest, Sherifi received a $15,000 check from
    a man named Elbaytam, who lived in Raleigh and attended the same
    mosque as Sherifi.       Elbaytam may have intended the funds for
    charity, consistent with the Muslim custom of “zakat,” i.e.,
    charitable giving based on accumulated wealth.            Sherifi advised
    informant Eddarkoui, however, that the money would instead be
    used to support jihadist efforts.           On July 23, 2009, Sherifi
    deposited $5,000 cash into his bank account.
    Sherifi also spoke with Boyd about his desire to travel
    abroad to join in violent jihad.            In June 2008, Sherifi told
    Boyd about the challenges that Sherifi faced in obtaining the
    necessary travel documents.        Sherifi also speculated that when
    “there was Shari’ah” he could travel anywhere.               J.A. 4035. 13
    13
    Shari’ah is a term used to generally describe the moral
    and religious rules of Islam, as well as its teachings.
    29
    Boyd suggested that if Sherifi could not travel, he should “make
    jihad” in the United States.          
    Id. Sherifi promptly
    responded in
    the affirmative, intoning “Inshallah,” or “God willing.”                 
    Id. In July
    of 2008, Sherifi was finally able to travel, and he
    departed for Kosovo.          Sherifi advised some friends in Raleigh
    that he would be visiting family, while telling others that he
    was “looking for a way to go somewhere to make Jihad.”                         J.A.
    765-66.     Boyd and Sherifi thereafter remained in close contact,
    continuing their discussions about violent jihad.                 Boyd advised
    Sherifi about getting to the “battlefield” and finding others
    who adhered to his and Boyd’s extremist Islamic views.                  Boyd and
    Sherifi    also   discussed    Sherifi’s     plans   while   he   was    abroad.
    Sherifi hoped ultimately to travel to Jerusalem, and he also
    considered travelling to Chechnya or Syria to aid in violent
    jihadist movements.       In January 2009, Sherifi wrote Boyd that he
    had obtained travel documents to a location that, though not his
    planned    destination,    was   “a   good   place   to   seek    the   greatest
    pleasure of Allah.”        
    Id. at 4011.
            Sherifi also remained in
    contact with informant Eddarkoui, advising him of efforts to
    obtain weapons and participate in weapons training with like-
    minded persons in Kosovo.        In November of 2008, Sherifi wrote to
    Eddarkoui that “Allah ha[d] opened a way for [him].”                     
    Id. at 4009.
        Zakariya explained that opening or finding a way, in the
    context of violent jihad, meant that Allah had provided a “safe
    30
    route    that    you   wouldn’t     get   in     trouble    through   to   reach   a
    current battlefield.”         
    Id. at 2468-69.
    In January 2009, the FBI introduced a third confidential
    source into its investigation:                 Melvin Weeks, a Staff Sergeant
    in the United States Army at Camp Bondsteel, Kosovo.                          After
    meeting at a local mosque, Sherifi and Weeks soon became good
    friends.        Sherifi,     who   believed      that   jihad   meant   “to   fight
    physically with weapons against the enemies of Islam, wherever
    they are at and whoever they might be,” J.A. 1947, thereafter
    began to discuss his violent jihadist beliefs with Weeks and
    made efforts to convert him.                   As Weeks explained, jihad, to
    Sherifi, was not “the jihad of the Prophet Mohammad,” but rather
    “just murderous acts against innocent soldiers and civilians.”
    
    Id. at 2018.
          Over the next few months, Sherifi provided Weeks
    with literature and videos, including a video of a beheading,
    coupled with the explanation that it was “[w]hat happens to the
    one who leaves the din,” i.e., one who leaves the religion of
    Islam.      
    Id. at 1973.
              Sherifi also introduced Weeks to the
    teachings of al-Awlaki, providing him with an al-Awlaki writing
    entitled “44 Ways to Support Jihad,” in which the Imam explained
    how devoted “brothers” could assist violent jihadist causes by
    providing    money     and   translating        extremist   texts,    among   other
    things.     Weeks testified that Sherifi believed the “whole point
    of governance” was to impose Shari’ah law, and that Sherifi did
    31
    not    respect   any    other   form     of    government.          
    Id. at 2001-02.
    According to Weeks, Sherifi viewed everyone who did not share
    Sherifi’s beliefs in violent ideology to be an enemy of Islam,
    including     “[e]verybody        that    America      [or     its        allies    were]
    fighting against.”        
    Id. at 1949.
    While Sherifi was abroad in Kosovo, he also spent time with
    some     like-minded      individuals         who   agreed     with       Sherifi       and
    advocated violent jihad.            As a prime example of such contacts,
    Sherifi spoke with Bajram Asllani, also known as Abu Hatab, who
    was a native of Kosovo.             Asllani, at the time of trial, was
    “wanted by the United States government” on “charges of material
    . . . support      to   terrorism      and     conspiracy      to    kill,      maim    and
    injure    overseas.”       J.A.     2897.       Asllani       was   also       wanted    in
    Serbia, where he had been tried and convicted in absentia for
    his involvement in a “conspiracy to blow up several buildings.”
    
    Id. After Sherifi
    returned to the United States from Kosovo, he
    maintained contact with Asllani, speaking with him at least once
    using a video camera on a computer.                  According to Sherifi’s own
    testimony, he spoke with Asllani several times and translated
    documents    for   him,    though    Sherifi        claimed    never      to    have    met
    Asllani in person.          Sherifi also wired Asllani money so that
    Asllani, who was still in Kosovo, could obtain travel documents.
    32
    b.
    During the course of his conspiratorial activities, Boyd
    secured and maintained an extensive firearm and weapons arsenal,
    which he kept in and about his home and vehicles.               Boyd and his
    sons    generally     carried   firearms    on   their    persons,   and     Boyd
    regularly purchased large quantities of ammunition.                    Zakariya
    explained      that     Boyd    focused     on   obtaining     armor-piercing
    ammunition as well as deadly hollow-point handgun ammunition.
    Beginning in 2008, Boyd voiced an interest in relocating his
    family overseas and talked about moving to Jordan.                   Boyd even
    began    to   sell    his   personal   property,   including    some    of    his
    firearms, in preparation for such a move.                 Boyd was concerned
    that he would not be able to travel with his entire arsenal and,
    as a result, built a weapons bunker beneath his back porch and
    deck, where he planned to store some of the firearms.                  In July
    2009, Boyd, Sherifi, and Harris spent several days working on
    the     weapons   bunker.       The    weapons   bunker    consisted    of    an
    entrenchment roughly six feet deep and was lined with sandbags
    for protection and stability.
    c.
    In May 2009, Sherifi returned to the United States from
    Kosovo, leaving his wife in that Balkan country.                Sherifi told
    friends in Raleigh that he had returned to North Carolina to
    save money to buy a family farm in Kosovo.                   Sherifi advised
    33
    others that he planned for the farmland in Kosovo to be used by
    his jihadist “brothers” en route to the “battlefield.”
    That spring, Boyd and Sherifi discussed and developed a
    scheme    to   attack       the    Quantico       Marine         Corps      Base     in   eastern
    Virginia.      While abroad, Sherifi had identified Camp Bondsteel
    in   Kosovo    as     a     potential       target         for     attack,         because       the
    “brothers” hated the presence of American soldiers in Kosovo.
    After     returning       to    this      country,      Sherifi            worked    delivering
    medical supplies to various locations, including the Fort Bragg
    Army Post in North Carolina.                 Sherifi boasted to Boyd about how
    easy it was, as a delivery truck driver, to access such military
    facilities.         Boyd    and     Sherifi      then      identified          Quantico        as   a
    target, in part because Boyd was already familiar with Quantico,
    having lived there as a child.                    As a result, Boyd travelled to
    Quantico to get a closer look, supplementing his reconnaissance
    efforts    with     online        research      on   Google           and    other    websites.
    Following his visit to Quantico, Boyd reported to Sherifi that
    it was easy to access the base.
    On    several        occasions,       Boyd      and    Sherifi          discussed         their
    planned attack        on    Quantico,        and,    at     least       once      talked       about
    kidnapping     a    Marine      officer,        “a   general          or    someone       of   high
    rank.”      J.A.     1697.         Boyd    proposed        holding          the     officer     for
    ransom, seeking        in      return     the    release         of    an    Islamic      scholar
    being imprisoned by the United States.                       As part of this scheme,
    34
    Boyd    suggested    cutting   off    the    Marine’s    ring   finger       and
    “sen[ding] his finger with one of his rings” to Marine officials
    so that the Marines would “know it was him” and that he was
    Boyd’s prisoner.      
    Id. d. In
    the summer of 2009, Sherifi participated in two weapons
    training   sessions    in   Caswell   County,    North   Carolina.       Those
    sessions involved Boyd and others, including informants Harris
    and Eddarkoui.      The first session occurred on June 10, 2009, and
    the second was conducted about a month later, on July 7, 2009.
    The sessions took place on a rural property that Harris had
    obtained   for   weapons     training,      telling   the   group    that    it
    belonged to one of his relatives.             The property was actually,
    however, under government control and FBI surveillance.                     Boyd
    organized the “practice” sessions with the “idea . . . that they
    would use this [training] in furtherance if they were to go to
    try and fight somewhere.”       J.A. 1820.      During the sessions, Boyd
    instructed his trainees on military tactics and weapons skills,
    showing them how to use a variety of firearms.               At the second
    session, Boyd taught the trainees more about military maneuvers.
    Boyd also had his trainees practice their firearms skills while
    he fired automatic weapons, so that they would become accustomed
    to using weapons while being subjected to the sound of gunfire.
    35
    Sherifi attended and participated in both training sessions, and
    he sought to recruit others to the second session.
    On July 22, 2009, soon after the second training session,
    the initial indictment was returned in these proceedings.                   Boyd
    and his coconspirators had planned a third session for July 27,
    2009, the very date on which they were arrested.                   After the
    arrests, the FBI seized Boyd’s weapons arsenal from his home,
    together   with   various   and   sundry   gas   masks,    computers,       cell
    phones, and cash. 14   Fifteen of the firearms were loaded at the
    time of their seizure.        A corresponding search of the North
    Carolina home of Sherifi’s parents resulted in the seizure of
    packed suitcases and a money belt containing $10,000 in cash.
    B.
    During   the   trial, the      appellants     raised    a     number     of
    evidentiary   objections    and   reiterated     various   First    Amendment
    arguments, some related to the court’s jury instructions.                     On
    October 7, 2011, at the close of the government’s case, the
    appellants moved for judgments of acquittal.               The trial court
    14
    At the time of the initial indictment and during his
    ongoing conspiratorial activities, Boyd possessed more than
    forty weapons.  Boyd’s arsenal included assault weapons, sniper
    rifles, handguns, shotguns, and tens of thousands of rounds of
    ammunition. See J.A. 4274-79 (cataloging Boyd’s arsenal). Boyd
    had at least ten assault weapons, including several Bushmasters
    and AK-47s; at least twenty rifles and shotguns; and more than a
    dozen handguns.
    36
    denied    each      of     the    acquittal       requests,          explaining          that   the
    evidence, viewed in the light most favorable to the prosecution,
    was   sufficient         for     the    jury     to    find   each     of     the    appellants
    guilty of the charged offenses.                        The appellants renewed their
    acquittal motions — again on sufficiency grounds — at the close
    of all the evidence, and then again after the jury returned its
    verdicts.      The acquittal motions were all denied.
    The    prosecution’s            closing        argument       reiterated          the    key
    evidence      linking          each     of      the    appellants        to       the     charged
    conspiracies, focusing on the covert and secretive nature of the
    appellants’ plans.               The prosecution sought to underscore the
    violent tendencies of the appellants and their coconspirators,
    as    evidenced      by    their       fascination       with    weapons,          postings      on
    Facebook, and day-to-day communications with one another.                                       The
    prosecutors         also       explained        the     government’s          view        of     the
    evidence,     particularly             Boyd’s    testimony,       plus      that     of       expert
    Kohlmann concerning home-grown terrorism cells.                             Conversely, the
    defense      lawyers       focused       on     what    they     characterized            as    the
    scattered      and         vague        evidence        supporting          the      conspiracy
    allegations,        contending          that     the    prosecution          had     failed       to
    establish     any     concrete         object     thereof,       resulting          in    a    fatal
    deficiency in its case.                 Moreover, the defense lawyers attacked
    the    credibility         of    Boyd     and     his    sons,       arguing        that       their
    potential      to    receive          life     sentences       had    been     substantially
    37
    reduced by their testimony against the appellants.                            The defense
    also    asserted      that      the     FBI       informants      were      not    credible,
    emphasizing     that       all    had        been      paid    for    their       testimony.
    Finally, the lawyers stressed that, under the First Amendment,
    the    appellants     should      not       be    convicted     because      the    evidence
    against them consisted primarily of protected speech and, in any
    event, failed to prove the charged conspiracies.
    On   October       13,    2011,      after        the   closing      arguments    and
    instructions,       the    jury    deliberated           and   returned      its    separate
    verdicts.       On    January         13,     2012,      the   court     sentenced      each
    appellant,    and     it    thereafter           filed    three    sentencing       opinions
    explaining the sentences imposed.                        These consolidated appeals
    followed.     We possess jurisdiction pursuant to 28 U.S.C. § 1291
    and 18 U.S.C. § 3742(a). 15
    III.
    By    their        appeals,          the       appellants       challenge        their
    convictions    in     multiple        respects.           First,     they    contend    that
    their convictions cannot stand because the trial court committed

    this case by our district court colleague, who patiently
    addressed the various issues presented. The record convincingly

    reversible error in its First Amendment analysis.                                 Second, the
    appellants        pursue    recognition        of    several       evidentiary        errors,
    seeking relief by way of a new trial.                          Finally, they maintain
    that their motions for judgments of acquittal were erroneously
    denied, in that the trial evidence was legally insufficient to
    sustain     any    of   their     convictions.            We   begin     with       the    First
    Amendment, followed by other issues.
    A.
    The      appellants       contend       that    the      trial     court       committed
    reversible      error      in   its    handling      of   the      argument        that    their
    speech      espousing      violent         jihad    was   protected          by     the    First
    Amendment.        Concomitantly, the appellants assert that they never
    agreed    to    take    action        in   connection       with    their         beliefs    and
    expressions, and thus were prosecuted purely for their offensive
    discourse.         Of   course,       their    argument        ignores       that    the    jury
    found — as it was required to do in order to convict — that the
    appellants had, in fact, agreed to take action in furtherance of
    violent jihad.
    1.
    The First Amendment provides that “Congress shall make no
    law . . . abridging the freedom of speech.”                         U.S. Const. amend.
    I.    The Supreme Court has explained that, “as a general matter,
    the   First       Amendment     means       that     government        has    no     power    to
    restrict       expression       because      of    its    message,       its      ideas,     its
    39
    subject matter, or its content.”                    United States v. Stevens, 
    559 U.S. 460
    ,     468     (2010)     (internal        quotation          marks    omitted).
    Notwithstanding the foregoing, the First Amendment’s protections
    are     not     absolute,      and    the   Court       has      approved        government
    “restrictions       upon      the    content     of    speech       in    a   few   limited
    areas, . . . including obscenity, defamation, fraud, incitement,
    and speech integral to criminal conduct.”                           
    Id. (citations and
    internal quotation marks omitted).                   Moreover, the Court has been
    clear    that     prohibited         conduct        cannot    “be    labeled        ‘speech’
    whenever the person engaging in the conduct intends thereby to
    express an idea.”             Wisconsin v. Mitchell, 
    508 U.S. 476
    , 484
    (1993) (internal quotation marks omitted).
    The statutes underlying the appellants’ various convictions
    serve, inter alia, to criminalize providing, and conspiring to
    provide, material support for terrorism, see 18 U.S.C. § 2339A;
    conspiring to murder, kidnap, or maim outside the United States,
    
    id. § 956(a);
           and   conspiring       to    kill    a   federal         officer   or
    employee, 
    id. § 1117.
                   Often, those offenses involve speech.
    For example, the § 2339A convictions in United States v. Stewart
    were premised on evidence that the defendants provided material
    support — personnel — to a § 956(a) conspiracy by communicating
    to the conspirators the messages of “‘spiritual’ leader” Abdel
    Rahman that were intended to induce “criminal acts of violence.”
    See 
    590 F.3d 93
    , 112-16 (2d Cir. 2009).                             The Second Circuit
    40
    rejected the defendants’ First Amendment argument that, because
    “the     government         established       only        that     they     provided       the
    underlying conspiracy with Abdel Rahman’s ‘pure speech,’” the
    defendants          “did       not      provide          ‘personnel’        within         any
    constitutional interpretation of section 2339A.”                             
    Id. at 115.
    In so doing, the Stewart court determined that the issue was one
    of protected speech, rather than pure speech, and that Rahman’s
    “call to arms” was not protected.                   
    Id. The court
    explained that
    “[w]ords that instruct, solicit, or persuade others to commit
    crimes       of    violence      violate      the        law    and   may    be    properly
    prosecuted.”             
    Id. (alteration and
       internal     quotation         marks
    omitted).
    The     appellants’       First     Amendment           contention    is    somewhat
    different         than    that   of     the    Stewart          defendants.         As     the
    appellants would have it, their convictions unconstitutionally
    rest on their own protected speech, i.e., mere expressions of
    belief    in      violent      jihad.      The      appellants        invoke      Holder    v.
    Humanitarian Law Project, 
    130 S. Ct. 2705
    (2010), wherein the
    Supreme Court recently entertained a First Amendment challenge
    to 18 U.S.C. § 2339B (making it a federal crime to knowingly
    provide material support or resources to “a foreign terrorist
    41
    organization” designated as such by the Secretary of State). 16
    The   Humanitarian    Law      Project     plaintiffs   “claimed    that    they
    wished to provide support for the humanitarian and political
    activities of [foreign terrorist organizations in Turkey and Sri
    Lanka] in the form of monetary contributions, other tangible
    aid, legal training, and political advocacy, but that they could
    not do so for fear of prosecution under § 
    2339B.” 130 S. Ct. at 2714
    .      Although      the     Supreme      Court   concluded     that,   “in
    prohibiting the particular forms of support that plaintiffs seek
    to provide to foreign terrorist groups, § 2339B does not violate
    the freedom of speech,” 
    id. at 2730,
    the Court emphasized “that
    Congress   has   [not]      banned   [the     plaintiffs’]   pure    political
    speech,” 
    id. at 2722
    (internal quotation marks omitted).                    That
    is,
    [u]nder the material-support statute, plaintiffs may
    say anything they wish on any topic.   They may speak
    and   write  freely  about  the   [foreign  terrorist
    organizations], the governments of Turkey and Sri
    16
    The Humanitarian Law Project decision concerned the
    constitutionality of § 2339B, rather than § 2339A.      Section
    2339A(a) prohibits the provision of “material support or
    resources” while “knowing or intending that they are to be used
    in preparation for, or in carrying out,” violations of certain
    terrorism   statutes.      Meanwhile,   § 2339B(a)(1) prohibits
    “knowingly provid[ing] material support or resources” to an
    organization that has been designated as a “foreign terrorist
    organization” by the Secretary of State. Thus, both § 2339A and
    § 2339B criminalize the provision of “material support,” but
    they have some different elements.        See United States v.
    Chandia, 
    514 F.3d 365
    , 372 (4th Cir. 2008).
    42
    Lanka, human rights, and international law.    They may
    advocate before the United Nations.        . . .    The
    statute does not prohibit independent advocacy or
    expression of any kind.    Section 2339B also does not
    prevent plaintiffs from becoming members of the
    [organizations] or impose any sanction on them for
    doing so.    Congress has not, therefore, sought to
    suppress ideas or opinions in the form of “pure
    political speech.”    Rather, Congress has prohibited
    “material support,” which most often does not take the
    form of speech at all. And when it does, the statute
    is carefully drawn to cover only a narrow category of
    speech to, under the direction of, or in coordination
    with foreign groups that the speaker knows to be
    terrorist organizations.
    
    Id. at 2722-23
        (alteration        and    internal     quotation   marks
    omitted); see also 
    Stewart, 590 F.3d at 115
    (“The government
    does not deny that section 2339A may not be used to prosecute
    mere advocacy or other protected speech, but contends that the
    defendants were prosecuted for criminal actions that did not
    amount to protected speech.”).
    The appellants rely on Humanitarian Law Project for the
    proposition that they could not be convicted under § 2339A for
    simply     speaking,     writing   about,     or   even   joining   a    terrorist
    organization.      That proposition, however, does not undermine any
    of the appellants’ convictions.              Their convictions rest not only
    on their agreement to join one another in a common terrorist
    scheme,     but   also    on   a   series    of    calculated    overt    acts   in
    furtherance of that scheme.          For example, each of the appellants
    travelled abroad seeking to reach locations considered to be
    jihadist battlefields, with the hope and intent of engaging in
    43
    violent jihad.          To prepare themselves for jihad, the appellants
    trained with weapons and took instruction from Boyd.                                 Moreover,
    Sherifi    and     Yaghi       endeavored           to    recruit        others     into     the
    conspiracies:           Sherifi       through        explicit       efforts        to   recruit
    Sergeant Weeks, and Yaghi by introducing Mohammad and Hassan to
    Boyd.
    Furthermore,       it    was      entirely        consistent       with      the    First
    Amendment to make “evidentiary use of [the appellants’] speech
    to establish the elements of [their] crime[s] or to prove motive
    or intent.”        See 
    Mitchell, 508 U.S. at 489
    .                          Indeed, because
    “the    essence    of    a     conspiracy          is    an   agreement       to    commit    an
    unlawful act,” United States v. Jimenez Recio, 
    537 U.S. 270
    , 274
    (2003) (emphasis added) (internal quotation marks omitted), the
    supporting       evidence       may      necessarily          include       a      defendant’s
    speech.    See United States v. Rahman, 
    189 F.3d 88
    , 117 (2d Cir.
    1999)    (including       conspiracy          in    list      of    offenses       that    “are
    characteristically committed through speech”).                            Such is the case
    here, where the appellants engaged in extensive conversations
    with Boyd and others about the necessity of waging violent jihad
    and    their   shared     goal      of    reaching        the      jihadist      battlefield.
    Meanwhile,     evidence        such      as   Sherifi’s         discussions        with    Weeks
    about the religious obligation to engage in jihad, as well as
    Sherifi’s statements to Eddarkoui about plans to recruit Weeks
    for    violent    jihad        in   Somalia,        allowed        the    jury     to     attach
    44
    nefarious intent to what otherwise might have been considered
    innocent    acts.         As    further      examples,        Hassan’s      and       Yaghi’s
    Facebook postings advocating violent jihad, as well as their
    conversations      with    Boyd      to    that     effect,       serve   as    compelling
    support for the jury’s finding that Hassan and Yaghi travelled
    abroad with the hope of acting on their beliefs by engaging in
    jihad and fighting against the “kuffar.”
    As    the    Sixth     Circuit        explained       with    regard      to     another
    terrorism    prosecution         under     18     U.S.C.    § 2339A,      “[f]orming        an
    agreement to engage in criminal activities — in contrast with
    simply talking about religious or political beliefs — is not
    protected speech.”             United States v. Amawi, 
    695 F.3d 457
    , 482
    (6th Cir. 2012).          In that case, “although the conspiracy was
    closely     related    to,       and       indeed    proved        by,    many       of    the
    defendants’ conversations about political and religious matters,
    the conviction was based on an agreement to cooperate in the
    commission [of] a crime, not simply to talk about it.”                               
    Id. The Amawi
    analysis is readily applicable here.                         Put succinctly, the
    First   Amendment     was       no   bar    to    the   government’s           use    of   the
    appellants’      speech    to    demonstrate         their    participation           in   the
    charged conspiracies.
    2.
    In any event, the appellants contend that the jury was not
    fully instructed — and thus misled — on the scope of the First
    45
    Amendment’s     protections.       The    trial    court’s     First    Amendment
    instruction advised the jury as follows:
    I turn your attention now to the First Amendment to
    the United States Constitution, which establishes
    certain rights which accrue to each defendant.     The
    First Amendment provides, in part, that Congress shall
    make no law respecting an establishment of religion or
    prohibiting the free exercise thereof or abridging the
    freedom of speech or of the press or the right of the
    people to be peaceably assembled.       The right of
    freedom of speech and to engage in peaceful assembly
    extends to one’s religion and one’s politics.   Having
    instructed you concerning rights of each defendant
    pursuant to the First Amendment, I also instruct you
    that the First Amendment is not a defense to the
    crimes charged in the indictment.
    J.A.    3567-68.     Although     the    appellants    offered       eleven   other
    First Amendment instructions, their appeal focuses on just three
    of     those   proposals.       Specifically,       they     argue    that    their
    proposed instructions 37, 40, and 45 were erroneously excluded
    from     the   court’s   charge     to    the     jury. 17     Those     proposed
    instructions were as follows:
    17
    The appellants also challenge on First Amendment grounds
    the trial court’s rejection of proposed instruction 28. Rather
    than pertaining to any protections accorded by the First
    Amendment, however, that proposal reflects the appellants’
    (incorrect) interpretation of the elements of the Count One
    conspiracy.
    The appellants have further suggested that the trial
    court’s charge was not just deficient but also incorrect,
    because the court affirmatively instructed that the First
    Amendment was not a defense to the crimes charged.        The
    appellants failed to adequately address that claim in their
    opening brief, however, and therefore have abandoned it.  See
    Edwards v. City of Goldsboro, 
    178 F.3d 231
    , 241 n.6 (4th Cir.
    (Continued)
    46
    Number 37:     [Each appellant’s] right to exercise
    religion guarantees his right to believe and profess
    whatever religious doctrine he desires.
    Number 40:   The First Amendment protects speech that
    encourages others to commit violence, unless the
    speech is capable of producing imminent lawless
    action.    Speech that makes future violence more
    likely, such as advocating for illegal action at some
    indefinite time in the future, is protected.    Thus,
    speech may not be punished just because it makes it
    more likely that someone will be harmed at some
    unknown time in the future.
    Number 45:   The First Amendment right to free speech
    protects the right of an individual or group to
    advocate for the use of force or advocate for the
    violation of law so long as the speech is:     1) not

    Pursuant to Rule 30(d) of the Federal Rules of Criminal
    Procedure, “[a] party who objects to any portion of the
    instructions or to a failure to give a requested instruction” is
    required to “inform the court of the specific objection and the
    grounds   for   the  objection   before   the    jury  retires   to
    deliberate.” A “failure to object in accordance with this rule”
    will, in most instances, preclude appellate review. See United
    States v. Ebersole, 
    411 F.3d 517
    , 526 (4th Cir. 2005).          The
    appellants    made  arguments   in   favor    of   their   proposed
    instructions — including numbers 37, 40, and 45 — prior to the
    court’s charge to the jury.    The record reveals, however, that
    the appellants only identified instructions 37, 47, and 48 in
    their post-charge objections. Nevertheless, the government does

    We review for abuse of discretion a trial court’s decision
    to either give or refuse to give a proposed instruction.                       See
    United   States    v.   Lighty,   
    616 F.3d 321
    ,    366    (4th    Cir.   2010)
    (internal quotation marks omitted).             In assessing a claim of
    instructional error, “we do not view a single instruction in
    isolation; rather we consider whether taken as a whole and in
    the context of the entire charge, the instructions accurately
    and   fairly   state     the   controlling     law.”         United   States   v.
    Passaro, 
    577 F.3d 207
    , 221 (4th Cir. 2009) (internal quotation
    marks omitted).         Thus, “[a] district court commits reversible
    error in refusing to provide a proffered jury instruction only
    when the instruction (1) was correct; (2) was not substantially
    covered by the court’s charge to the jury; and (3) dealt with
    some point in the trial so important, that failure to give the
    requested instruction seriously impaired the defendant’s ability
    to conduct his defense.”           
    Lighty, 616 F.3d at 366
    (internal
    quotation marks omitted).
    Even if the three rejected instructions correctly recite
    the   legal       principles      espoused     therein,        the    appellants
    nevertheless fail in two essential respects.              That is, they have
    not, however, raise any contention of waiver for failure of the
    appellants   to  properly   object under  Rule   30(d).    More

    three instructions at issue.

    dealt with points so important that the court’s failure to give
    them seriously impaired the appellants’ ability to conduct their
    defenses.       The court’s First Amendment instruction substantially
    covered the appellants’ right to freely exercise and express
    their      religious     beliefs,       echoing       proposed      instruction       37.
    Proposals       40     and     45,     encompassing       the       First      Amendment

    import     in   this    case.        Put    simply,    the   appellants        were   not
    prosecuted for inciting violence, cf., e.g., 
    Stewart, 590 F.3d at 115
    ,      nor    would     the       instructions      have      permitted      any
    convictions      on    that    ground.       Accordingly,       the    court    did   not
    abuse its discretion by declining to give — in haec verba —
    proposed instruction 37, 40, or 45. 19

    Additionally, Hassan raises the trial court’s failure to
    instruct on the Second Amendment insofar as it “protects an
    individual right to possess a firearm unconnected with service
    in a militia, and to use that [weapon] for traditionally lawful
    purposes, such as self-defense within the home.”    See J.A. 463
    (further specifying that mere possession of a firearm “does not
    in and of itself make a defendant guilty of a crime”). Notably,
    Hassan was neither charged with nor convicted of any offense
    involving his possession of a firearm, and he cannot show that
    the lack of a Second Amendment instruction prejudiced his
    defense.
    49
    B.
    We turn now to the various evidentiary issues presented by
    the appellants.        First, they assert that the trial court erred
    in    admitting    the    opinion     evidence       of     Evan     Kohlmann,     the
    government’s expert witness.              Next, Hassan and Yaghi maintain
    that the admission of their Facebook pages and certain videos
    was   erroneous.         Hassan     and    Yaghi     also    challenge       selected
    evidence   against     them   as    being      inadmissible        lay   opinion    and
    improper hearsay.        Finally, Yaghi contends that the court erred
    in admitting evidence that the prosecution obtained improperly
    pursuant to FISA court orders.
    We assess challenges to a trial court’s evidentiary rulings
    for abuse of discretion.           See United States v. Hornsby, 
    666 F.3d 296
    , 307 (4th Cir. 2012).            In reviewing an evidentiary ruling
    under that standard, “we will only overturn [a] ruling that is
    arbitrary and irrational.”          United States v. Cole, 
    631 F.3d 146
    ,
    153 (4th Cir. 2011) (internal quotation marks omitted).                            With
    those principles in mind, we address the various evidentiary
    challenges.
    1.
    The appellants first contend that the expert testimony of
    Evan Kohlmann was inadmissible under Federal Rule of Evidence
    702   because     it   was    irrelevant       and   failed        to    satisfy    the
    foundational requirements established by the Supreme Court in
    50
    Daubert   v.   Merrell   Dow   Pharmaceuticals,   Inc.,   
    509 U.S. 579
    (1993).   The appellants also maintain that, even if Kohlmann’s
    evidence was admissible under Rule 702, it was yet inadmissible
    under Rule 403 because its probative value was outweighed by the
    potential for unfair prejudice.
    a.
    As the Supreme Court has explained, Rule 702 “imposes a
    special obligation upon a trial judge to ensure that any and all
    scientific testimony is not only relevant, but reliable.”          Kumho
    Tire Co., Ltd. v. Carmichael, 
    526 U.S. 137
    , 147 (1999) (internal
    quotation marks omitted). 20       In Daubert, the Court identified
    five factors for use in evaluating the reliability of proposed
    expert testimony:
    (1) whether the particular scientific theory “can be
    (and has been) tested”; (2) whether the theory “has
    been subjected to peer review and publication”; (3)
    20
    Pursuant to Rule 702, “[a] witness who is qualified as an
    expert by knowledge, skill, experience, training, or education
    may testify in the form of an opinion or otherwise” if the
    following requirements are satisfied:
    (a) the expert’s scientific, technical, or other
    specialized knowledge will help the trier of fact to
    understand the evidence or to determine a fact in
    issue; (b) the testimony is based on sufficient facts
    or data; (c) the testimony is the product of reliable
    principles and methods; and (d) the expert has
    reliably applied the principles and methods to the
    facts of the case.
    Fed. R. Evid. 702.
    51
    the “known or potential rate of error”; (4) the
    “existence and maintenance of standards controlling
    the technique’s operation”; and (5) whether the
    technique has achieved “general acceptance” in the
    relevant scientific or expert community.
    See United States v. Crisp, 
    324 F.3d 261
    , 265-66 (4th Cir. 2003)
    (quoting 
    Daubert, 509 U.S. at 593-94
    ).                   The Daubert test is
    flexible; “[r]ather than providing a definitive or exhaustive
    list, Daubert merely illustrates the types of factors that will
    bear on the inquiry.”          
    Id. at 266.
    On April 30, 2010, the government alerted the appellants
    that it intended to call Kohlmann as an expert witness with
    respect to various aspects of Islamic extremism.                  Specifically,
    it   was   anticipated     that     Kohlmann     would      testify   about    the
    “meaning and context of various words and phrases used by the
    defendants which are commonly used by persons practicing extreme
    Islam”; the “structure and leadership of groups adhering to the
    principles     of    Islamic    extremism”;     and   the   “manner    and    means
    employed by extremist Islamic groups to recruit individuals and
    the process of radicalization which occurs within such groups.”
    J.A. 204-07.        The appellants sought to bar Kohlmann’s testimony,
    asserting,     inter    alia,     that   the    prosecution     was   unable    to
    satisfy the Daubert test.
    The trial court — after conducting a Daubert evidentiary
    hearing and allowing ample opportunity for cross-examination of
    Kohlmann   —    denied    the    pretrial      exclusion    motion    by   written
    52
    opinion.      See United States v. Boyd, No. 5:09-cr-00216 (E.D.N.C.
    Sept. 16, 2011), ECF No. 1443 (the “Daubert Opinion”).                                       The
    court therein determined that Kohlmann’s proposed testimony was
    both     reliable          and      relevant,       thus       satisfying       Rule     702’s
    requirements.             To its credit, the court did not rule broadly
    that all of Kohlmann’s potential testimony was relevant.                                     The
    court instead made clear that it would not “allow testimony on
    all    of    the    information           included      in    Kohlmann’s      very     lengthy
    expert reports,” 
    id. at 6,
    explaining that “the government is on
    notice      that     only      expert      testimony         relevant    to   the     case   is
    admissible         and    it     should    tailor       its    examination      of    Kohlmann
    accordingly,”            
    id. at 11.
         The     trial      court    also   noted     that
    questions about Kohlmann’s credentials and opinions were “ideal
    fodder for vigorous cross examination.”                        
    Id. at 8.
    The trial court did not abuse its discretion in deciding
    that Kohlmann’s proposed evidence satisfied Rule 702.                                The court
    heard and considered testimony about Kohlmann’s credentials and
    techniques and was convinced that he possessed “the requisite
    knowledge, skill, experience, training, and education to testify
    on various aspects of the trend of decentralized terrorism and
    homegrown terrorism.”                Daubert Opinion 7.                 In so ruling, the
    court       gave     particular           attention      to     the     Daubert       factors,
    including      thorough          assessments       of    whether      Kohlmann’s       methods
    were subject to peer review, his “consultation with others in
    53
    the field,” and “whether or not his research findings [were]
    based in a sound methodology.”              
    Id. at 9
    .
    The     trial    court’s      assessment        of    Kohlmann’s          credentials
    fulfilled       its    gatekeeping       obligation         under    Daubert,          and   the
    court did       not    err    in   deciding     that    Kohlmann’s         testimony         was
    reliable as well as relevant to the issues to be presented.
    Notably, we have previously approved of Kohlmann’s expertise in
    terrorism matters, ruling that his testimony would “assist the
    trier of fact to understand the evidence or to determine a fact
    in issue.”        See United States v. Benkahla, 
    530 F.3d 300
    , 309
    (4th Cir. 2008) (internal quotation marks omitted). 21                           There, the
    trial evidence was also “complicated, touching by necessity on a
    wide        variety    of     ideas,     terms,    people,          and     organizations
    connected to radical Islam.”                
    Id. at 309.
                We thus ruled that
    the    trial     court       had   not   abused    its       discretion          in    deeming
    “lengthy testimony about various aspects of radical Islam . . .
    appropriate, and indeed necessary, for the jury to understand
    the evidence and determine the facts.”                         
    Id. at 310
    (internal
    quotation       marks       and    punctuation    omitted).               That        reasoning
    applies equally today, because the evidence in this case was
    21
    Our Benkahla analysis focused largely on the relevance of
    Kohlmann’s testimony because, as Judge Wilkinson explained,
    Kohlmann’s “qualifications were obviously substantial and the
    district court acted well within its discretion in determining
    that they were sufficient.” See 
    Benkahla, 530 F.3d at 309
    n.2.
    54
    similarly        complex,     involving         the    testimony      of      multiple
    coconspirators and informants.              The evidence in each case also
    involved     terminology      and     concepts        that   were    likely     to    be
    unfamiliar to jurors.         In such settings, the relevance of expert
    testimony is quite evident.
    b.
    The appellants also challenge the trial court’s failure to
    exclude Kohlmann’s testimony under Rule 403, maintaining that
    its probative value was substantially outweighed by the risk of
    unfair prejudice. 22        We apply a “highly deferential” standard of
    review to such an issue, and a trial court’s “decision to admit
    evidence over a Rule 403 objection will not be overturned except
    under      the     most     extraordinary        circumstances,        where         that
    discretion has been plainly abused.”                  United States v. Udeozor,
    
    515 F.3d 260
    ,    265    (4th    Cir.   2008)      (internal     quotation    marks
    omitted).        We have emphasized that relevant evidence should only
    be excluded under Rule 403 “when there is a genuine risk that
    the emotions of a jury will be excited to irrational behavior,
    and this risk is disproportionate to the probative value of the
    22
    Pursuant to Rule 403, a trial court “may exclude relevant
    evidence if its probative value is substantially outweighed by a
    danger of . . . unfair prejudice, confusing the issues, [or]
    misleading the jury.”
    55
    offered evidence.”             United States v. Siegel, 
    536 F.3d 306
    , 319
    (4th Cir. 2008).
    Here, the district court carefully balanced — both before
    and during trial — the relevance of Kohlmann’s testimony against
    the potential prejudice arising therefrom.                      Although linking the
    appellants          to     extremist      jihadist       groups     was        undoubtedly
    prejudicial, it was not unfairly so.                     Indeed, the charges that
    were lodged against the appellants meant that the prosecution
    would necessarily seek to establish that link.                            See 
    Benkahla, 530 F.3d at 310
        (rejecting    Rule    403    challenge       to   Kohlmann’s
    testimony,         despite    potential     prejudice,      where       relevance    could
    not be doubted and trial judge could decide that probative value
    outweighed any prejudicial risk); United States v. Williams, 
    445 F.3d 724
    ,    730    (4th    Cir.    2006)     (explaining          that,     though
    prejudicial, “as is all evidence tending to show a defendant’s
    guilt,”       the    challenged      evidence      was    nevertheless         admissible
    because       the   risk     of   unfair   prejudice      did     not    “substantially
    outweigh the probative value of the evidence” (emphasis added)).
    In these circumstances, the court did not abuse its discretion
    in overruling the appellants’ Rule 403 objections. 23
    23
    The appellants also assert that Kohlmann’s testimony was
    irrelevant under Rules 401 and 402 because “[c]riminal behavior
    must be judged by the conduct of individual defendants applied
    to the particularized elements of the pertinent criminal
    statute, not the characteristics of any class of defendants ‘as

    Next,   Hassan    and     Yaghi   contend    that   several    prosecution
    exhibits consisting of Facebook pages and the files embedded
    therein — including videos hosted on YouTube (and maintained by
    Google)    —    were     not     properly      authenticated.        Hassan    also
    challenges,     on     hearsay    and     other    grounds,   two    videos   used
    against him by the prosecutors.                First, he maintains that the
    court erred in admitting a physical training video that he had
    posted on a website called RossTraining.com.                    Second, Hassan
    claims that a video seized from his cell phone by the FBI was
    also erroneously admitted.
    a.
    The trial court ruled that the Facebook pages and YouTube
    videos were self-authenticating under Federal Rule of Evidence
    902(11), and thus that they were admissible as business records.
    That    the    Facebook        pages     and   YouTube     videos    were     self-
    authenticating business records was not, however, the end of the
    trial court’s inquiry.           The court also required the government,
    pursuant to Rule 901, to prove that the Facebook pages were
    linked to Hassan and Yaghi.

    assertion   constitutes  a   distinct  relevancy  challenge  to
    Kohlmann’s testimony, it is rejected.

    Rule    902(11)     authorizes      the       admission    in    evidence         of
    records that satisfy the requirements of Rule 803(6)(A)-(C), “as
    shown by a certification of the custodian . . . that complies
    with    a   federal    statute    or   a   rule      prescribed    by    the    Supreme
    Court.”       Rule 803(6), in turn, provides that business records
    are admissible if they are accompanied by a certification of
    their custodian or other qualified person that satisfies three
    requirements:         (A) that the records were “made at or near the
    time by — or from information transmitted by — someone with
    knowledge”;      (B)    that   they    were      “kept     in    the    course      of   a
    regularly      conducted    activity       of    a    business”;       and    (C)    that
    “making the record was a regular practice of that activity.” 24
    Turning to Rule 901, subdivision (a) thereof provides that, to
    “establish that evidence is authentic, the proponent need only
    present     ‘evidence    sufficient        to    support    a    finding      that   the
    matter in question is what the proponent claims.’”                           See United

    find that the evidence is authentic.”               
    Id. Hassan’s and
       Yaghi’s   Facebook       pages       were    captured      via
    “screenshots,” taken at various points in time and displaying
    Hassan’s     and     Yaghi’s     user     profiles        and     postings.           The
    screenshots of the Facebook pages also included photos and links
    to the YouTube videos.           On the Facebook pages, Hassan and Yaghi
    had posted their personal biographical information, as well as
    quotations and listings of their interests.                     Each Facebook page
    also contained a section for postings from other users, on what
    is called a “wall.”             Meanwhile, the videos in question were
    retrieved     from        Google’s      server.           In     establishing         the
    admissibility of those exhibits, the government presented the
    certifications       of   records    custodians      of    Facebook       and     Google,
    verifying that the Facebook pages and YouTube videos had been
    maintained     as    business     records     in    the    course       of    regularly
    conducted      business         activities.               According          to    those
    certifications, Facebook and Google create and retain such pages
    59
    and videos when (or soon after) their users post them through
    use of the Facebook or Google servers. 25
    After evaluating those submissions, the trial court ruled
    that the requirements of Rule 902(11) had been satisfied.                                 The
    court then determined that the prosecution had satisfied its
    burden      under    Rule   901(a)      by     tracking      the    Facebook     pages     and
    Facebook      accounts      to    Hassan’s      and     Yaghi’s      mailing     and     email
    addresses         via    internet         protocol          addresses.         In        these
    circumstances,          there     was     no        abuse    of     discretion      in    the
    admissions of any of the Facebook pages and YouTube videos.
    b.
    Turning to the physical training video uploaded by Hassan
    to    RossTraining.com,          Hassan      maintains       that    the   trial    court’s
    refusal      to     admit   his    own       related        postings   contravened        the
    evidentiary “rule of completeness.”                         The rule of completeness
    has its origins at common law, and is codified in Rule 106 of
    the   Federal       Rules   of    Evidence.           Pursuant      thereto,     “[w]hen    a
    writing or recorded statement or part thereof is introduced by a
    25
    The appellants’ contention that the Facebook and Google
    certifications are insufficient because they were made for
    litigation purposes several years after the postings occurred is
    entirely unpersuasive.    It would make no sense to require a
    records custodian to contemporaneously execute an affidavit
    attesting to the accuracy of a business record each time one is
    created or maintained, when there is no pending litigation or
    need for such a certification.
    60
    party, an adverse party may require the introduction at that
    time    of    any    other        part    or    any     other       writing       or    recorded
    statement          which     ought        in         fairness        to     be         considered
    contemporaneously with it.”                     United States v. Moussaoui, 
    382 F.3d 453
    ,       481     (4th    Cir.        2004)    (internal          quotation       marks
    omitted).      As we have explained, a trial court, in applying the
    rule    of    completeness,         may     allow       into       the    record        “relevant
    portions      of    [otherwise]          excluded      testimony          which    clarify       or
    explain the part already received,” in order to “prevent a party
    from misleading the jury” by failing to introduce the entirety
    of the statement or document.                   See United States v. Bollin, 
    264 F.3d 391
    ,    414       (4th     Cir.    2001).         Nevertheless,            the    rule    of
    completeness does not “render admissible . . . evidence which is
    otherwise inadmissible under the hearsay rules.”                                United States
    v. Lentz, 
    524 F.3d 501
    , 526 (4th Cir. 2008) (internal quotation
    marks omitted).            Nor does the rule of completeness “require the
    admission      of    self-serving,         exculpatory             statements      made     by    a
    party which are being sought for admission by that same party.”
    
    Id. The physical
            training         video       posted        by      Hassan        on
    RossTraining.com           depicted       Hassan        in     a    series        of    physical
    training workouts.           It opened with a series of quotations on the
    video screen, such as “[t]here is no God but ALLAH and Muhammad
    is his Messenger,” the “strong Muslim is better than the weak
    61
    Muslim,” and “[l]et’s please ALLAH and train hard.”                                   Trial Ex.
    399; J.A. Vol. XIV.              The training video concluded with the words
    “support       our    troops,”      which      appeared       on   the    screen      above    an
    Arabic phrase and an image of an assault rifle.                                   
    Id. After Hassan
          had     uploaded      the      training    video      to     RossTraining.com,
    other        users     of    the     website         posted    various          comments      and
    questions,         some     of   which       were    critical      of     Hassan.        Hassan
    responded to them with postings of his own, including an apology
    for any controversy his training video had caused.                                Hassan then
    posted additional statements about his beliefs and his support
    of those troops fighting “for the truth.”                          J.A. 2377.         In one of
    those        subsequent     postings,         Hassan    said       that    he    “do[es]      not
    support terrorists.”               
    Id. 26 Hassan’s
    defense lawyer thus sought
    to introduce into evidence — under the rule of completeness —
    26
    Hassan’s   assertion  that   he   “do[es]                              not     support
    terrorists” was part of a lengthier statement:
    The troops I support are the ones who fight for truth,
    whether   he  is  Arab,   American,  Spanish,  Europe,
    whatever, it doesn’t matter as long as he fights for
    the truth. PS, I do not support terrorists.
    J.A. 2377.         In posting his apology, Hassan asserted:
    Islam is a religion of peace but when attacked we
    fight back strong.   I will edit the video but will
    probably keep my religious beliefs . . . because part
    of my religious faith is to become strong and in
    healthy shape.
    
    Id. at 2377-78.
    62
    the follow-up statements posted by Hassan.             The court, however,
    sustained the hearsay objection interposed by the prosecution
    and excluded those statements.
    Hassan’s excluded statements, though possibly exculpatory,
    do not fall within any hearsay exception that would authorize
    their admission into evidence.          Nor was the jury likely to have
    been confused or misled by their exclusion.                The court simply
    ruled that Hassan’s follow-up postings on RossTraining.com could
    not be used to establish the truth of any matter asserted —
    specifically, to show that Hassan did not support terrorists.
    That ruling was not an abuse of the court’s discretion.
    c.
    Hassan next challenges the prosecution’s use against him of
    the video that the authorities had seized from his personal cell
    phone.   The cell phone video showed Hassan firing a rifle at an
    outdoor location near the Islamic Center in Raleigh.                     Hassan
    maintains   that   the   cell   phone    video   was   irrelevant    to     the
    prosecution’s case because it was not created until early 2009,
    two years after he stopped having regular contact with Boyd.
    Hassan also   contends    that,   even    if   relevant,    the   cell    phone
    video was unduly prejudicial under Rule 403, because it shows
    Hassan using a firearm and thereby could have caused the jury to
    improperly associate Hassan with Boyd’s weapons arsenal.
    63
    Because       the     cell     phone      video        was    relevant       to   Hassan’s
    weapons training with Yaghi, it was also relevant to whether
    Hassan was yet involved — even in 2009 — in the ongoing Count
    One conspiracy.            As for Hassan’s claim of prejudice, “[t]he mere
    fact that the evidence will damage the defendant’s case is not
    enough — the evidence must be unfairly prejudicial, and the
    unfair prejudice must substantially outweigh the probative value
    of the evidence.”            See 
    Williams, 445 F.3d at 730
    .                        Put simply,
    the cell phone video of Hassan firing a rifle did not present a
    sufficient “danger of unfair prejudice” to warrant its exclusion
    under   Rule        403.      Indeed,        at      least      one      government      witness
    admitted that there was no reason to believe that Hassan’s mere
    possession or firing of the rifle was illegal.                                 Moreover, there
    was no suggestion that Hassan or Yaghi had participated in the
    weapons    training         sessions       of     2009        or    in    the     creation     and
    preservation of Boyd’s weapons arsenal.                            In these circumstances,
    the   trial    court        did    not    err     in    its     ruling      with     respect    to
    Hassan’s cell phone video.
    3.
    Hassan and Yaghi next contend that three witnesses gave
    improper      lay    opinion       evidence        when       they       testified      to   their
    understandings         of     what       Hassan        and    Yaghi       meant    by    certain
    statements      or     on    particular         occasions.               The    following      are
    challenged as erroneously admitted:                          (1) Boyd’s understanding of
    64
    what Hassan and Yaghi meant in statements to Boyd during face-
    to-face conversations and in email exchanges; (2) Dylan Boyd’s
    understanding of why Hassan and Yaghi wanted to accompany the
    Boyds on their 2007 trip to the Middle East; and (3) Jamar
    Carter’s testimony regarding his understanding of Yaghi’s use of
    the phrase “jihad.”
    Pursuant to Federal Rule of Evidence 701, a lay witness may
    testify to opinions when such evidence is “(a) rationally based
    on     the   witness’s    perception;        (b)      helpful    to     clearly
    understanding the witness’s testimony or to determining a fact
    in issue; and (c) not based on scientific, technical, or other
    specialized knowledge within the scope of Rule 702.”                  Rule 701
    thus   “allows   testimony    based   on     the    person’s    reasoning    and
    opinions about witnessed events.”            United States v. Offill, 
    666 F.3d 168
    , 177 (4th Cir. 2011).             Lay witnesses are not entitled
    to opine broadly or generally; rather, “lay opinion testimony
    must be based on personal knowledge.”              United States v. Johnson,
    
    617 F.3d 286
    , 292 (4th Cir. 2010).              In contrast to Rule 702,
    which governs expert testimony, Rule 701 “permits lay testimony
    relating to a defendant’s hypothetical mental state.”                   
    Offill, 666 F.3d at 177
    .     Applying those principles, we have ruled that
    testimony    regarding    a   witness’s      understanding      of    what   the
    defendant    meant   by   certain     statements       is   permissible      lay
    testimony, so long as the witness’s understanding is predicated
    65
    on his knowledge and participation in the conversation.                                         See,
    e.g., United States v. Min, 
    704 F.3d 314
    , 325 (4th Cir. 2013);
    
    Offill, 666 F.3d at 177
    -78.
    Having     evaluated       the       trial     court’s         admission        of    the
    challenged lay opinion testimony, we are satisfied that none of
    its       rulings    constituted          an    abuse       of    discretion.             In    each
    instance, the lay testimony stemmed directly from the witness’s
    conversations with Hassan and Yaghi, and was therefore based on
    that witness’s perceptions.                    Furthermore, the testimony clearly
    assisted the jury in understanding the appellants’ conversations
    and statements.              Lay opinion testimony is particularly useful
    when, as here, the terms and concepts being discussed, such as
    “kuffar,”          “best     brothers,”         finding          “the        battlefield,”       and
    “shahid,”          are     likely    to    be     unfamiliar            to     the   jury.        In
    particular, the government introduced a substantial amount of
    evidence      relating         to   the    coded      and    convoluted          communications
    between the conspirators.                  In such circumstances, the witnesses
    were entitled, under Rule 701, to explain their understandings
    and impressions of Hassan’s and Yaghi’s statements and actions.
    As    a    result,       the    court’s        rulings      with    respect          to   the    lay
    evidence were not an abuse of its discretion.
    4.
    Hassan     and     Yaghi    next       maintain         that        certain     evidence
    admitted by the trial court constituted inadmissible hearsay.
    66
    Rule 801 of the Federal Rules of Evidence defines hearsay as any
    statement that a “declarant does not make while testifying at
    the current trial,” and that is offered “in evidence to prove
    the truth of the matter asserted in the statement.”
    First, Hassan contends that Boyd’s testimony regarding a
    conversation between Boyd and a shared acquaintance (the “mutual
    contact”) of Hassan’s father and Boyd constituted multi-level
    hearsay.       Boyd explained that the “mutual contact” advised him
    that   Hassan’s       father    “believed          both    [Hassan         and   Yaghi]     had
    travelled with [Boyd] to . . . try to get to a battlefield.”
    J.A.    1760    (emphasis       added).             Hassan       maintains        that    this
    statement      was    admitted       to    establish       that       he   had,    in     fact,
    travelled      with    Boyd    to     the     Middle      East    with      the    hope     and
    intention      of    making    it    to     the    battlefield.            The    government
    contends to the contrary:                 that such testimony was not admitted
    for the truth of the matter asserted, but simply to establish
    Boyd’s understanding of why Hassan’s father was angry with Boyd,
    thus providing context for a phone call between the two men.
    Boyd’s testimony about his phone conversation with Hassan’s
    father was not inadmissible hearsay.                      Assessed in the context of
    the other evidence, the prosecution elicited the testimony in
    order to show the basis for Boyd’s belief that Hassan’s father
    was angry with Boyd.                As the prosecution demonstrated, Boyd’s
    interactions         with     the     elder        Hassan,       as    well       as     Boyd’s
    67
    understanding of rumors in the Raleigh Islamic community about
    the travel of Hassan and Yaghi to the Middle East in 2007, were
    relevant at trial, in that they offered a plausible explanation
    for the cessation of Boyd’s relationship with Hassan and Yaghi.
    Second, turning to a specific hearsay challenge interposed
    by Yaghi, he maintains that a police detective’s testimony that
    law   enforcement       began   to   investigate        Yaghi    in   2006      after
    “receiv[ing] information from the Muslim community that [he] was
    traveling     to   Jordan    . . .   with   the   intent    to    participate      in
    jihad in Iraq,” J.A. 2256, constituted inadmissible hearsay.                       As
    with Boyd’s testimony about the elder Hassan, the prosecution
    contends    that    the     detective’s     testimony    was     simply   used    as
    relevant background, and to explain the origins of the Yaghi
    investigation.         Because Yaghi did not object at trial to the
    detective’s        testimony      concerning       the     origins        of      the
    investigation, we review Yaghi’s hearsay challenge solely for
    plain error.       See United States v. Smith, 
    441 F.3d 254
    , 262 (4th
    Cir. 2006).
    Under    plain    error    review,    an    appellate      court    may    only
    correct an error when:          “(1) there is an error; (2) the error is
    plain; (3) the error affects substantial rights; and (4) the
    court determines, after examining the particulars of the case,
    that the error ‘seriously affect[s] the fairness, integrity, or
    public reputation of judicial proceedings.’”                    United States v.
    68
    Williamson, 
    706 F.3d 405
    , 411 (4th Cir. 2013) (quoting United
    States v. Olano, 
    507 U.S. 725
    , 732 (1993)).                                    The plain error
    standard is thus a high bar that is difficult to clear.                                             To
    establish     that      an    error     affected             his    substantial         rights,     an
    appellant must demonstrate that “the error actually affected the
    outcome     of    the       proceedings.”              
    Id. (internal quotation
             marks
    omitted).        Even if the first three prongs of plain error review
    have been satisfied, an appellant must convince the reviewing
    court     that        the     error     “seriously             affect[s]          the    fairness,
    integrity,        or    public        reputation             of     judicial       proceedings.”
    
    Olano, 507 U.S. at 732
    .
    Put    simply,         the      trial       court       did       not    plainly       err    in
    admitting the detective’s testimony.                           In context, his statement
    concerning        the       inception        of        the     Yaghi       investigation            was
    presented        as    background       to    explain             how    the   law      enforcement
    officer became involved in the case.                              The detective’s statement
    also supports the inference, however, that some members of the
    Muslim community of Raleigh believed that Yaghi had travelled
    abroad with the hope of engaging in jihad, and that some in the
    law enforcement community likewise thought that Yaghi had done
    so.     Nevertheless, the government introduced a vast amount of
    other    trial        evidence     to    that          effect.            Thus,    even      if    the
    detective’s       statements          would   have           been       subject   to     a   hearsay
    69
    objection,        the    court’s     admission      thereof    would     not    satisfy
    either of the final two prongs of plain error review.
    5.
    On July 27, 2009, well before trial, the government gave
    notice     that     it    intended     to   use     evidence     it   had      collected
    pursuant to FISA.            The appellants moved to suppress the FISA
    evidence,       or,      alternatively,       for    disclosure        of     the   FISA
    materials. 27      The district court, after an in camera and ex parte
    review of the FISA materials, denied the appellants’ motion and
    explained its reasoning.              See United States v. Boyd, No. 5:09-
    cr-00216    (E.D.N.C.       June     22,    2011),   ECF   No.    1174      (the    “FISA
    Opinion”).        Yaghi challenges the rulings embodied in the FISA
    Opinion, asserting that the electronic surveillance orders were
    not supported by probable cause because, when the orders were
    issued in June 2007, there was no evidence that Yaghi was an
    agent of a foreign power, as required by FISA.                              Yaghi seeks
    disclosure of the FISA materials to support his contentions or,
    in the alternative, asks that we review those materials de novo
    to assess whether probable cause existed.
    27
    The FISA applications, as well as the electronic
    surveillance orders issued by the FISA Court and any returns
    filed in connection with them, are collectively referred to as
    the “FISA materials.”
    70
    FISA established a detailed framework whereby the executive
    branch     “could      conduct     electronic        surveillance       for       foreign
    intelligence purposes without violating the rights of citizens.”
    United States v. Hammoud, 
    381 F.3d 316
    , 332 (4th Cir. 2004) (en
    banc), vacated on other grounds, 
    543 U.S. 1097
    (2005).                            Subject
    to      certain     exceptions         not        relevant      here,        “electronic
    surveillance      of    a    foreign      power    or    its   agents       may   not   be
    conducted unless the FISA Court authorizes it in advance,” and
    “[e]ach application to the FISA Court must first be personally
    approved     by     the      Attorney      General.”           United        States     v.
    Squillacote,      
    221 F.3d 542
    ,    553     (4th      Cir.    2000)    (internal
    quotation    marks      omitted).          Where,       as   here,    the    target     of
    electronic surveillance is a “United States person,” the FISA
    Court
    may issue an order authorizing the surveillance only
    if the FISA judge concludes that there is probable
    cause to believe that the target of the surveillance
    is a foreign power or agent of a foreign power, that
    proposed minimization procedures are sufficient under
    the terms of the statute, that the certifications
    required by [50 U.S.C.] § 1804 have been made, and
    that the certifications are not clearly erroneous.
    
    Id. (internal quotation
    marks omitted). 28
    28
    The FISA provisions, in pertinent part, define a “United
    States person” as “a citizen of the United States, [or] an alien
    lawfully   admitted  for   permanent  residence.”     50  U.S.C.
    § 1801(i). Yaghi, as a naturalized citizen of this country, is
    a United States person.
    71
    FISA identifies several requirements for the government’s
    use of information obtained pursuant to a FISA order, as well as
    the essential procedures for challenging a prosecutor’s use of
    such    information.           See       50    U.S.C. §    1806.        Under       those
    procedures, a defendant may move to suppress evidence that was
    “obtained or derived from such electronic surveillance,” where
    the information was “unlawfully acquired” or “the surveillance
    was not made in conformity with an order of authorization or
    approval” under FISA.           
    Id. § 1806(e).
               When faced with such a
    suppression motion, “if the Attorney General files an affidavit
    under oath that disclosure or an adversary hearing would harm
    the national security of the United States,” 
    id. § 1806(f),
    “the
    district      court   must    review      in   camera     and   ex   parte    the    FISA
    application and other materials necessary to rule,” 
    Squillacote, 221 F.3d at 553
    .
    FISA    provides      that    a    district      court    may   only     divulge
    “portions of the application, order, or other materials relating
    to the surveillance . . . where such disclosure is necessary to
    make    an     accurate      determination         of     the    legality      of    the
    surveillance.”        50 U.S.C. § 1806(f); see United States v. Rosen,
    
    447 F. Supp. 2d 538
    , 546 (E.D. Va. 2006).                       We have emphasized
    that, where the documents “submitted by the government [are]
    sufficient” to “determine the legality of the surveillance,” the
    72
    FISA materials should not be disclosed.                  
    Squillacote, 221 F.3d at 554
    .
    Because the Attorney General filed an appropriate affidavit
    in this case, in response to the appellants’ motion to suppress,
    the district court conducted an in camera and ex parte review of
    the FISA materials and determined that there was probable cause
    to support the FISA orders.                  The court then articulated and
    correctly applied the principles established by FISA and our
    precedent,     reviewing    the      FISA     materials       “de    novo    with    no
    deference accorded to the . . . probable cause determinations,
    but   with     a     presumption        of     validity        accorded      to      the
    certifications.”        FISA    Opinion       15.      Moreover,      as    the    court
    recognized, because the statutory application was properly made
    and approved by a FISA judge, it carried a strong presumption of
    veracity and regularity.             
    Id. at 14-15;
    see United States v.
    Pelton, 
    835 F.2d 1067
    , 1076 (4th Cir. 1987).
    We    have    conducted     an    independent       review      of    the     FISA
    materials    and    likewise    conclude        that    the    FISA    applications
    demonstrated probable cause to believe that Yaghi was an agent
    of a foreign power when the FISA orders were issued.                              Having
    conducted    that    review,    we     are    satisfied       that    the   materials
    submitted to the court by the government were sufficient to show
    73
    that the FISA surveillance was proper.              We therefore decline to
    order any further disclosure of the FISA materials. 29
    C.
    Having resolved the appellants’ evidentiary challenges that
    bear on admissibility, we turn to their principal contention on
    appeal:     that the evidence was insufficient to support their
    various convictions.         At the close of the prosecution’s case-in-
    chief, at the conclusion of the trial evidence, and after the
    jury’s return of its verdicts, the appellants challenged the
    sufficiency of the evidence.           The district court ruled that each
    of their challenges was without merit, as articulated in the
    court’s   opinions      of   October    10   and   December   1,   2011.   See
    Sufficiency Opinion I; United States v. Boyd, No. 5:09-cr-00216
    (E.D.N.C.   Dec.   1,    2011),   ECF    No.   1558   (“Sufficiency    Opinion
    II”).
    29
    We have heretofore reviewed de novo a district court’s
    determination that a FISA application established probable
    cause. 
    Squillacote, 221 F.3d at 554
    ; 
    Hammoud, 381 F.3d at 331
    .
    Some of our sister circuits, however, have utilized a more
    deferential standard of review. See, e.g., United States v. El-
    Mezain,   
    664 F.3d 467
    ,  567   (5th Cir.   2011)  (conducting
    “independent in camera review” and applying abuse of discretion
    standard); United States v. Abu-Jihaad, 
    630 F.3d 102
    , 130 (2d
    Cir. 2010) (explaining that “FISA warrant applications are
    subject to minimal scrutiny by the courts, both upon initial
    presentation and subsequent challenge” (internal quotation marks
    omitted)). We are satisfied that probable cause existed in this
    case under any of these standards.
    74
    We review de novo a trial court’s denial of a motion for
    judgment of acquittal.         See United States v. Osborne, 
    514 F.3d 377
    , 385 (4th Cir. 2008).              Applying that standard, it is well
    settled that “[t]he verdict of a jury must be sustained if there
    is substantial evidence, taking the view most favorable to the
    [g]overnment, to support it.”                 Glasser v. United States, 
    315 U.S. 60
    ,   80   (1942).        As    we    have    explained,          “substantial
    evidence”     is   that   which   “a    reasonable         finder    of    fact   could
    accept as adequate and sufficient to support a conclusion of a
    defendant’s guilt beyond a reasonable doubt.”                   United States v.
    Moye, 
    454 F.3d 390
    , 394 (4th Cir. 2006) (en banc) (internal
    quotation marks omitted).           We examine “circumstantial as well as
    direct evidence,” and remain mindful that “a conviction may rely
    entirely on circumstantial evidence.”                 United States v. Bonner,
    
    648 F.3d 209
    , 213 (4th Cir. 2011).                    In so doing, we accord
    deference to “the jury’s resolution of all evidentiary conflicts
    and    credibility     determinations.”              
    Id. Simply put,
      “[a]
    defendant challenging the sufficiency of the evidence faces a
    heavy burden.”      
    Id. (internal quotation
    marks omitted).
    After our independent and de novo review of the voluminous
    trial record, we are satisfied that the evidence presented was
    sufficient to sustain the appellants’ various convictions.                         The
    evidence,     though      largely      circumstantial,         was        nevertheless
    substantial.       That evidence readily supports the determination
    75
    that a rational finder of fact could (and in fact did) deem the
    evidence adequate to support each conviction beyond a reasonable
    doubt.
    1.
    We turn first to Yaghi, who challenges the sufficiency of
    the   evidence   on    the    Count   One    and    Count   Two    conspiracies,
    maintaining in particular that none of the evidence supports an
    inference   that      he     agreed   to    participate     therein.         Yaghi
    emphasizes that Boyd and his sons denied under oath entering
    into any agreements with him, and he argues that it was not
    otherwise   proved     that     he    had   entered     into      even   a   tacit
    conspiratorial agreement.
    To convict Yaghi on Count One, the government was obliged
    to prove:   (1) that he entered into a conspiracy; (2) that the
    objective thereof was to provide material support or resources;
    and (3) that he then knew and intended that such support or
    resources would be used in preparation for, or in carrying out,
    a separate conspiracy to murder, kidnap, or maim outside of the
    United States.     See 18 U.S.C. § 2339A; United States v. Chandia,
    
    514 F.3d 365
    , 372 (4th Cir. 2008). 30              With respect to the first
    30
    Although the Indictment alleged a series of overt acts in
    furtherance of the Count One conspiracy, proof of the commission
    of an overt act in a § 2339A conspiracy is not required by
    statute.   See 18 U.S.C. § 2339A; see also 
    Stewart, 590 F.3d at 114-16
    (setting out elements of § 2339A without including overt
    (Continued)
    76
    element, the government was obliged to prove a conspiracy — that
    is,   an      agreement    between   two    or    more   persons     to   engage   in
    illegal activity.           See United States v. Burgos, 
    94 F.3d 849
    ,
    857-58 (4th Cir. 1996) (en banc). 31              Yaghi’s involvement in such
    a conspiracy was adequately demonstrated if the evidence showed
    “a slight connection between [him] and the conspiracy.”                       United
    States v. Kellam, 
    568 F.3d 125
    , 139 (4th Cir. 2009) (internal
    quotation marks omitted). 32           Furthermore, the “existence of a
    tacit        or   mutual   understanding     is   sufficient    to    establish    a
    act requirement); cf. supra note 2 (observing that                        appellants
    asserted at trial that overt act was not required).                        The Count
    Two conspiracy, by contrast, requires proof that at                        least one
    overt act in furtherance thereof was committed within                     the United
    States. See 18 U.S.C. § 956(a)(1).
    31
    The trial court instructed                 the   jury   on    the    law   of
    conspiracy, explaining that
    [i]f a defendant understands the unlawful nature of a
    plan or scheme and knowingly and intentionally joins
    in that plan or scheme on one occasion, that is
    sufficient to convict him for conspiracy, even though
    the defendant hadn’t participated before and even
    though the defendant played only a minor part.
    J.A. 3573-74.   The court also instructed that the prosecution
    had no obligation to “prove that a conspiracy has a discrete,
    identifiable organization structure.” 
    Id. at 3573.
         32
    The conspiracy instructions emphasized that a defendant
    can be a coconspirator “without knowing [the conspiracy’s] full
    scope or all of its members, and without taking part in the full
    range of its activities.” J.A. 3573. Moreover, the trial court
    advised the jury that “[o]nce a defendant willfully joins in a
    conspiracy,” he “is presumed to continue in that conspiracy
    unless and until he takes affirmative steps to withdraw.”    
    Id. at 3574.
    77
    conspiratorial agreement, and proof of such an agreement need
    not     be      direct    —     it    may    be    inferred     from    circumstantial
    evidence.”        
    Id. (internal quotation
    marks omitted). 33
    On        the    second    element      of    the   Count     One    conspiracy,
    “material support or resources” is defined as “any property,
    tangible        or    intangible,       or    service,”       including    “currency,”
    “training,”           “expert    advice      or     assistance,”        “weapons,”    or
    “personnel.”             18   U.S.C.    § 2339A(b)(1). 34        The    third   element
    required the government to establish that Yaghi acted “with the
    knowledge or intent” that such material support or resources
    would      be    used    to   commit    a    specific     violent      crime,   in   this
    instance a violation of 18 U.S.C. § 956.                      See 
    Stewart, 590 F.3d at 113
    .
    Turning to the Count Two conspiracy, the government was
    obliged to show that:                (1) Yaghi entered into a conspiracy; (2)
    knowing and intending that the objective thereof was murder,
    33
    The court explained to the jury that a conspiracy “may be
    proved wholly by circumstantial evidence,” J.A. 3572, which can
    consist of “a defendant’s relationship” with other conspirators
    and “the length of this association,” as well as “the
    defendant’s attitude and conduct, and the nature of the
    conspiracy,” 
    id. at 3573.
          34
    The court further defined “training” as “instruction or
    teaching designed to impart a specific skill as opposed to
    general knowledge,” J.A. 3574-75, and defined “personnel” as
    “one or more persons, which can include a defendant’s own
    person,” 
    id. at 3575.
    78
    kidnapping,     or   maiming   outside     the   United   States;   (3)   the
    conspiracy was entered into within the United States; and (4) a
    conspirator committed an overt act in furtherance thereof within
    the jurisdiction of the United States.            See 18 U.S.C. § 956(a);
    United States v. Wharton, 
    320 F.3d 526
    , 538 (5th Cir. 2003).
    After our de novo assessment of the evidentiary record, we,
    like the trial court, are satisfied that there was sufficient
    evidence   to   support   each   of   Yaghi’s     conspiracy   convictions.
    That evidence includes the following:
    •     In 2006, Yaghi sought           out Boyd at an Islamic
    center in Durham to ask          about Boyd’s experiences
    in Afghanistan.   Yaghi         and Boyd became friends,
    and Yaghi shared Boyd’s         beliefs in the necessity
    of violent jihad;
    •      In the fall of 2006, Yaghi travelled to Jordan,
    seeking   to  reach   the   battlefield.      Yaghi
    maintained contact with Boyd during the trip;
    •      Prior to and during his 2006 trip to Jordan,
    Yaghi discussed violent jihad with Boyd.  Before
    his departure, Yaghi asked Boyd how and where he
    could find the “best brothers,” and mentioned
    “finding a wife.”       Those terms were coded
    references for seeking others who shared Yaghi’s
    beliefs in violent jihad and could help Yaghi
    make his way to the battlefield;
    •      After returning from his 2006 trip to Jordan,
    Yaghi   brought   Hassan   to Boyd’s   home,   thus
    recruiting    another    man  to   the    terrorism
    conspiracies;
    •      Yaghi thereafter again sought Boyd’s assistance
    in travelling to the Middle East, and Boyd
    purchased plane tickets for Yaghi and Hassan to
    fly to Israel in the summer of 2007;
    79
    •    In 2007, as he prepared to travel to the Middle
    East with Hassan, Yaghi indicated a “readiness to
    join” Boyd in waging violent jihad;
    •    Yaghi flew to the Middle East with Hassan in 2007
    with the hope of engaging in violent jihad.
    Yaghi and Hassan were denied entry into Israel
    and were unable to reach the battlefield.     The
    men thereafter returned to the United States;
    •    Yaghi and Hassan made unsuccessful efforts to
    contact Boyd while they were in the Middle East
    in 2007;
    •    Yaghi facilitated an introduction between Boyd
    and defendant Jude Kenan Mohammad in 2008.
    Coupled with Mohammad’s subsequent departure for
    Pakistan and his “insistence” on finding “a way
    to the battlefield,” this evidence shows that
    Yaghi recruited Mohammad into both conspiracies.
    See Sufficiency Opinion I at 17; 35
    •    Yaghi posted messages on Facebook promoting his
    radical and violent jihadist beliefs.       Those
    postings continued after Yaghi’s contacts with
    Boyd diminished, justifying the jury’s finding
    that Yaghi and Hassan — independent of Boyd —
    continued to engage in initiatives in furtherance
    of the conspiracies; and
    •    In late 2007, Yaghi made a speech to an Islamic
    group in Raleigh, advocating that its members
    consider violent jihad.    From such statements,
    and from Yaghi’s efforts to convert others to his
    beliefs in violent jihad, the jury was entitled
    to find Yaghi’s continuing participation in the
    conspiracies.
    35
    In referencing the opinions of the district court on the
    sufficiency issues, we do not accord any deference to the
    court’s analysis; we quote those opinions only where we agree
    that they are supported by the record.
    80
    The trial evidence fully supports the jury’s finding that
    Yaghi believed in violent jihad and acted on those beliefs in
    concert with coconspirators.                   Yaghi understood and acquiesced in
    the   objectives       of    the       Count    One       and    Count    Two     conspiracies,
    i.e.,     providing         material       support           and      resources         for,     and
    committing acts of murder outside the United States.                                    Moreover,
    numerous    overt      acts    were        undertaken           in    furtherance        of     each
    conspiracy, including Yaghi’s 2007 trip to the Middle East and
    his   efforts     to    recruit         others        into      the    conspiracies.             The
    verdict against Yaghi must therefore be sustained.

    Sherifi       challenges            each        of        his      five      convictions,
    maintaining that, at best, the trial evidence reflected only his
    religious and political beliefs, and perhaps his approval of the
    misdeeds    of    others.          In     addition         to     proving       that    Sherifi’s
    conduct    fulfilled         the       elements       of     the      Counts      One    and     Two
    conspiracies,       the      government             was     required        to     satisfy       the
    elements of      the    other          charges      lodged        against    Sherifi.           With
    respect    to    Sherifi’s         fifth       offense       of      conviction,        the    Count
    Eleven    conspiracy,        the       government          was     obliged       to     show    that
    Sherifi    entered      into       a    conspiracy         to     kill    federal       employees
    engaged    in    the   performance             of    their       official        duties,       and   a
    conspirator committed an overt act in furtherance thereof.                                       See
    18 U.S.C. § 1117.            As to Counts Four and Eight — the firearms
    81
    charges —     the   prosecution     was      required    to   “present   evidence
    indicating that the possession of a firearm furthered, advanced,
    or helped forward a crime of violence.”                 United States v. Khan,
    
    461 F.3d 477
    ,   489   (4th   Cir.   2006)    (internal      quotation   marks
    omitted).     Count Four alleged that Sherifi possessed a firearm
    on June 10, 2009, in furtherance of the Count Two conspiracy,
    and Count Eight alleged that he possessed a firearm on July 7,
    2009, also in furtherance of the Count Two conspiracy.
    Substantial     evidence     supports       each    of    Sherifi’s    five
    convictions, beginning with the following that relates to his
    involvement in the Count One and Count Two conspiracies:
    •      In 2008, Sherifi grew close to Boyd, visiting in
    Boyd’s home and spending time with Boyd’s family.
    In discussions with Boyd, Sherifi confirmed his
    adherence to the violent jihadist ideology he
    shared with Boyd, plus the need to act in
    accordance therewith;
    •      Sherifi openly advocated his disdain for the laws
    and government of the United States, believing
    Shari’ah to be the true law;
    •      In 2008, Sherifi travelled to Kosovo, advising
    associates in Raleigh that he was going there to
    be closer to the battlefield;
    •      Sherifi talked with Boyd and others in Raleigh
    about his efforts to join violent jihadist
    efforts abroad, as well as his attempts to
    radicalize and recruit Sergeant Weeks;
    •      While in Kosovo, Sherifi participated in firearms
    training with like-minded individuals.    At one
    point, Sherifi was in contact with persons who
    82
    were considering Camp Bondsteel — where Weeks was
    stationed — as a target for jihad;
    •      Sherifi believed that jihad “was just murderous
    acts against innocent soldiers and civilians”;
    •      After returning to the United States, Sherifi
    assisted Boyd in preparing a bunker under Boyd’s
    home to conceal Boyd’s weapons arsenal;
    •      Sherifi participated in Boyd’s efforts to raise
    money to support violent jihadist causes, and
    gave Boyd $500 in cash to that end; and
    •       While back in the United States, Sherifi made
    efforts to raise funds to purchase “farmland in
    Kosovo   from  which   to   launch off  to  the
    battlefield” in Kosovo, Syria, and elsewhere.
    See Sufficiency Opinion I at 21.
    The foregoing evidence readily satisfies the elements of
    the Count One and Count Two conspiracies as to Sherifi.              Sherifi
    wilfully partook in those conspiracies, and sought to provide
    money and personnel to support violent jihadist causes, in this
    country and abroad.     Even more so than Yaghi and Hassan, Sherifi
    advocated   his   extreme   and   violent   beliefs    to   Boyd   and   other
    members of the conspiracy, demonstrating his intention to act on
    those beliefs.    The evidentiary record shows that a multitude of
    overt acts were committed in furtherance of the conspiracies,
    including   the   weapons   training     sessions,    the   construction    of
    Boyd’s weapons bunker, travel abroad, and consistent efforts to
    join violent jihadist battlefields.         The verdict against Sherifi
    on Counts One and Two must therefore be sustained.
    83
    The evidence supporting Sherifi’s conviction on the Count
    Eleven conspiracy included the following:
    •     In June 2008, Sherifi expressed to Boyd his
    willingness to wage violent jihad in the United
    States if unable to do so abroad;
    •     While   in    Kosovo,   Sherifi    discussed the
    possibility of targeting the American military
    post at Camp Bondsteel for violent jihad;
    •     In 2009, Boyd shared his plans to attack the
    Marine Corps Base at Quantico with Sherifi, who
    readily agreed to participate;
    •     Sherifi   told   Boyd    about   his   experiences
    delivering goods to Fort Bragg, explaining how a
    person could easily gain entry into an American
    military facility as a truck driver; and
    •      Boyd proposed kidnapping a Marine officer and
    took steps in connection with the Count Eleven
    plot, including touring Quantico and conducting
    research about the base.
    As   with   the   Count   One   and   Count   Two   conspiracies,   the
    evidence of Sherifi’s agreement with Boyd to participate in an
    attack on Quantico is sufficient to support his Count Eleven
    conviction.      Cf. In re Terrorist Bombings of U.S. Embassies in
    E. Africa, 
    552 F.3d 93
    , 113 (2d Cir. 2008) (deeming evidence
    sufficient to sustain § 1117 conviction).           The evidence is more
    than adequate to support a rational fact-finder’s determination
    that Sherifi knowingly joined Boyd in a plot to target Quantico
    for an attack, and that overt acts were committed in furtherance
    84
    thereof.        Sherifi’s conviction on the Count Eleven conspiracy
    must therefore also be sustained.
    Turning to Sherifi’s convictions on the firearms charges,
    those too must be upheld, given the prosecution’s evidence that
    Sherifi     participated            in    weapons      training          sessions        in   North
    Carolina on June 10 and July 7, 2009, where Boyd taught military
    tactics and weaponry skills in preparation for violent jihad.
    There     was    substantial             evidence      to    support          a   finding       that
    Sherifi, on both of those occasions, possessed and used at least
    one firearm for training purposes, in furtherance of the Count
    Two conspiracy.              Sherifi’s convictions on Counts Four and Eight
    are therefore also sustained.
    3.
    Hassan, who was convicted of the Count One conspiracy only,
    maintains that there was a dearth of evidence, testimonial or
    otherwise,           showing    that        he   entered          into    a       conspiratorial
    agreement       with        anyone.         Hassan    emphasizes          that      he    was    not
    involved        in     any     of     the    audio      recordings            introduced        into
    evidence, and that the FBI informants neither interacted with
    Hassan nor heard Boyd mention him.
    Reviewing the evidence de novo and acknowledging that the
    evidence        against        Hassan       is   not        as     overwhelming          as     that
    implicating           the     other       appellants,            there    was       nevertheless
    substantial evidence proving that Hassan was involved in the
    85
    Count     One   conspiracy. 36   The    evidentiary   support   for   his
    conviction includes the following:
    •      Beginning in 2006 and continuing through mid-
    2007, Hassan maintained regular contact with
    Boyd, often meeting at the Blackstone Halal
    Market;
    •      In 2006 and 2007 Boyd was stockpiling weapons and
    surrounding himself with like-minded individuals
    called “good brothers.”     Those brothers shared
    the view that the killing of non-Muslims was a
    prescribed obligation.    Yaghi and Hassan shared
    Boyd’s beliefs in the necessity of violent jihad;
    •      Seeking a jihadist battlefield, Yaghi travelled
    to Jordan in the fall of 2006.        While there,
    Yaghi maintained contact with Hassan, all the
    while expressing the hope that Hassan would make
    it to the battlefield.       Hassan also “offered
    veiled encouragement to defendant Yaghi while he
    was   on   this   expedition”    overseas.     See
    Sufficiency Opinion I at 12;
    •      In early 2007, Yaghi and Hassan sought Boyd’s
    assistance in obtaining plane tickets to travel
    to the Middle East;
    •      Before departing for the Middle East in 2007,
    Hassan and Yaghi sought Boyd’s advice, including
    methods of overseas travel to avoid detection.
    Boyd had discussions with Hassan “about killing
    and maiming.” 
    Id. at 13;
    36
    That Hassan was acquitted of the Count Two conspiracy is
    not accorded any weight in our analysis.    Even if that verdict
    is inconsistent with the guilty verdict on Count One, a jury is
    permitted to return an inconsistent verdict if it sees fit to do
    so. See United States v. Powell, 
    469 U.S. 57
    , 63 (1984). The
    question before us relates solely to the Count One conspiracy
    and whether — viewed in the light most favorable to the
    prosecution — that charge was properly proven against Hassan.
    86
    •   Hassan and Yaghi trained with weapons prior to
    their 2007 trip overseas as “part of their
    continued training” for violent jihad.  
    Id. at 20.
    •   During a drive with Boyd in 2007, Hassan
    brandished a .22 caliber rifle, which Hassan and
    Yaghi said they had purchased for training and
    target practice;
    •   In   2007,  exchanges   between Yaghi   and Boyd
    indicated that Boyd, who was experienced on the
    battlefield, validated the like-mindedness of
    Yaghi and Hassan. As the trial court related, a
    “readiness to join” Boyd “reasonably could be
    concluded” on Hassan’s part. 
    Id. at 12;
    •   Using plane tickets purchased through Boyd,
    Hassan travelled with Yaghi in 2007 to the Middle
    East, and sought to enter Israel and Palestine;
    •   Boyd advised his associates in Raleigh that he
    had asked Hassan and Yaghi to go overseas to
    engage in violent jihad;
    •   After   arriving in the Middle East, Hassan and
    Yaghi   sought on several occasions to contact
    Boyd;
    •   Following his return from the 2007 Middle East
    trip with Yaghi, Hassan’s contacts with Boyd
    diminished   substantially.     Another  set   of
    initiatives was then undertaken by Yaghi and
    Hassan that, as the trial court explained,
    “subscribed to [tenets] of violent jihad espoused
    by Daniel Boyd.” 
    Id. at 19;
    •   Hassan’s postings on Facebook and other social
    media confirmed his beliefs in violent jihad and
    demonstrated his desire to further the violent
    causes and ideology espoused by Boyd and others;
    •   The physical training video that Hassan posted on
    RossTraining.com   showed  his   determination to
    train physically for violent jihad;
    87
    •         Hassan showed Jamar Carter videos of car bombings
    and offered praise for the people fighting in
    such a manner.    Hassan’s view of jihad “deemed
    suicide bombings righteous.” 
    Id. at 19;
    •         Hassan’s nefarious intentions were substantiated
    when,   in  January  2009,  he   “instructed  his
    paramour to remove his postings on his Facebook
    page” as well as “postings on ‘Muslim Gangsta For
    Life,’” which endorsed his radical ideology. 
    Id. at 23;
    •         Hassan had ties to Anwar al-Awlaki and sought al-
    Awlaki’s counsel in early 2009 on an important
    matter; and
    •         Hassan’s connection to al-Awlaki, coupled with
    Kohlmann’s   explanation   of  al-Awlaki’s   far-
    reaching influence in the “development of home-
    grown terrorists,” 
    id. at 23-24,
    show that Hassan
    “endorsed, collected and distributed preachings
    [that] repeatedly called for Jihad against the
    United States.” 
    Id. at 25.
    In    these    circumstances,       there     was     substantial      evidence
    proving that       Hassan    joined    and    agreed     to   participate    in    the
    Count    One    conspiracy    and     that,   in   fact,      he    participated    in
    multiple overt acts in furtherance thereof.                        As a result, the
    trial evidence supports Hassan’s conviction on the Count One
    conspiracy, and his contention to the contrary is rejected.
    D.
    Before turning to the various sentencing issues presented
    here, I will exercise a point of personal privilege with respect
    to the investigation and prosecution of this important case.
    The trial record reveals that the appellants strove to conceal
    their nefarious activities from outsiders uncommitted to violent
    88
    revolution around the world, habitually congregating in secret
    to    discuss   their    plans     and   to    reinforce,      in     the   manner   of
    zealots,    each    other’s        resolve.          That    the     conspiracy      was
    infiltrated and almost all of its cohorts arrested before they
    could bring their criminal schemes to fruition should in no way
    inspire the conclusion that the appellants have been prosecuted
    for merely harboring ideas, convicted of nothing more than an
    Orwellian “thoughtcrime.”
    To the contrary, the evidence reveals that the appellants
    are   dangerous    men   who     freely    and       frequently      exercised     their
    constitutional      right     to    speak,      to     be    sure,    but    who    also
    demonstrated a steadfast propensity towards action.                         Before the
    appellants’ actions could escalate to visit grievous harm upon
    the government, other countries, or innocent civilians, the FBI
    and its associates timely intervened.                   The laudable efforts of
    law enforcement and the prosecutors have ensured that, on this
    occasion at least, we will not be left to second-guess how a
    terrorist attack could have been prevented.
    Absent the long reach of the federal conspiracy statutes,
    the government would have been forced to pursue the appellants
    with one hand tied behind its back.                   No such constraint served
    to hinder the investigation and prosecution of the appellants,
    however,    and    we   are   reminded        once    more   that     the   charge    of
    conspiring to commit a federal crime has yet to relinquish its
    89
    well-earned reputation as — in the words of Learned Hand — the
    “darling     of    the   modern     prosecutor’s               nursery.”          Harrison     v.
    United States, 
    7 F.2d 259
    , 263 (2d Cir. 1925).                                    Judge Hand’s
    profound observation is as true now as it was nearly ninety
    years ago.
    Over the course of the modern legal era, the pursuit of
    federal conspiracy convictions has doubtlessly been a boon to
    United     States      Attorneys.             And       it     is    eminently       fair      and
    reasonable to say that the implementing statutes — particularly
    those that dispense with the commission of an overt act as an
    element of the crime — sometimes paint with a broad brush.                                     Cf.
    Krulewitch v. United States, 
    336 U.S. 440
    , 450 (1949) (Jackson,
    J.,   concurring)        (“[T]he    conspiracy               doctrine      will    incriminate
    persons on the fringe of offending who would not be guilty of
    aiding   and      abetting     or   of    becoming            an    accessory,      for     those
    charges only lie when an act which is a crime has actually been
    committed.”).          But    our   system         of   government         and    law    reposes
    great and solemn trust in federal prosecutors to exercise their
    discretion        as   instruments       of    right          and   justice,       and    it    is
    therefore “for prosecutors rather than courts to determine when
    to use a scatter gun to bring down the defendant.”                               
    Id. at 452.
    Indeed, the societal utility of conspiracy prosecutions as
    a   weapon     against       evildoers        is    manifest         not    merely       in    the
    substantive elements of the offense, but also in the procedural
    90
    mechanisms enabling its ready proof, even against those only
    marginally involved.       See, e.g., Fed. R. Evid. 801(d)(1)(E) (“A
    statement . . . is not hearsay [that] was made by the party’s
    coconspirator during and in furtherance of the conspiracy.”).            A
    person intending to only be “in for a penny,” with the slightest
    connection to an established conspiracy, actually risks being
    “in for a pound.”     It is somewhat unique in this case that Boyd,
    the prosecution’s star witness, was also the ringleader of the
    conspiracies.       This    was   thus   a   top-down    prosecution   of
    conspiracy offenses, with Boyd and his sons — having departed
    the dock and ascended the witness stand — implicating others
    more peripherally involved.        That fact matters not, however, in
    the context of the criminal culpability of these appellants.
    Put succinctly, the specter of federal criminal liability cannot
    help but serve as an intense deterrent to those who otherwise
    would be bent on violence.
    We have faithfully applied the well-settled principles of
    conspiracy law in this case, both in letter and in spirit.              In
    so doing, we have come to the ineluctable conclusion that the
    government      legitimately      and    appropriately    charged      the
    appellants, and the convictions it thereby obtained are without
    infirmity.

    Finally, having rejected all challenges to the appellants’
    convictions,       we       turn          to       their    contentions             concerning        the
    sentences imposed by the district court.                                     The court announced
    those     sentences             during         a    January       13,        2012     hearing,        and
    thereafter filed a sentencing opinion as to each appellant.                                           See
    United    States       v.       Boyd,      No.      5:09-cr-00216            (E.D.N.C.        Jan.    18,
    2012), ECF No. 1653 (the “Sherifi Sentencing Opinion”); United
    States v. Boyd, No. 5:09-cr-00216 (E.D.N.C. Jan. 18, 2012), ECF

    Hassan,       who          was       convicted          of       solely      the       Count     One
    conspiracy,       had       a    base      offense         level      of     33     under     the    2011
    edition    of    the     Sentencing                Guidelines.          Because         the   district
    court    deemed    Hassan            to   be       subject       to    the    enhancement           for    a
    “federal crime of terrorism” under Guidelines section 3A1.4 (the
    “terrorism enhancement”), his offense level increased by twelve
    levels     to     45.             The      court          then     applied          two     additional
    enhancements to Hassan — a three-level adjustment for having
    selected victims on the basis of their religion, ethnicity, or
    national        origin,          see       
    id. § 3A1.1(a)
                (the     “hate         crime
    enhancement”),          and      a    two-level            adjustment         for    attempting           to
    92
    obstruct justice by asking his paramour to delete Facebook and
    other internet postings, see 
    id. § 3C1.1
    — resulting in a total
    offense    level   of    50.        The    court       declined        to   grant      Hassan’s
    request for a four-level “minimal participant” reduction under
    Guidelines section 3B1.2.             With the offense level of 50 and the
    terrorism enhancement’s automatic criminal history category of
    VI,   Hassan’s     advisory      Guidelines         range        was    life      in    prison.
    Nevertheless,      § 2339A(a)       of     Title       18   provides        for    a    maximum
    penalty of only fifteen years.                    Thus, Hassan’s advisory range
    fell to 180 months (fifteen years), which was the very sentence
    imposed.
    After applying both the terrorism enhancement and the hate
    crime enhancement to Yaghi, the sentencing court determined that
    his   adjusted     offense     level       was    48     and     his    criminal        history
    category was VI.         The resulting advisory Guidelines ranges were
    180 months for the Count One conspiracy and life imprisonment
    for the Count Two conspiracy.                   The court sentenced Yaghi to 180
    months on Count One and to a concurrent sentence of 380 months
    on Count Two, for an aggregate sentence of 380 months.
    Sherifi,     who   was    convicted         of     the     Count      One,       Two,   and
    Eleven    conspiracies,        plus       the    Count      Four    and      Eight      firearm
    offenses,    received     the    terrorism         enhancement,             the   hate    crime
    enhancement,       and    a     three-level            enhancement          for     targeting
    government     officers        or     employees             as     victims,        see        USSG
    93
    § 3A1.2(a).       The court calculated Sherifi’s advisory Guidelines
    ranges as follows:        180 months (the statutory maximum) on Count
    One; life in prison on Count Two; 60 months (consecutive to any
    other sentence) on Count Four; 300 months (consecutive to any
    other sentence) on Count Eight; and life in prison on Count
    Eleven.        Rather   than   a   life    sentence,    the    court      imposed    an
    aggregate sentence of 540 months. 37
    On appeal, each of the appellants challenges the sentencing
    court’s application of the terrorism enhancement.                      In addition,
    Hassan contends that the court erred in refusing to grant his
    request for a minimal participant reduction.                       Meanwhile, Yaghi
    and Sherifi challenge the substantive reasonableness of their
    sentences.
    B.
    1.
    The   primary    sentencing        issue   pursued     by    the   appellants
    relates to the district court’s application of the terrorism
    enhancement.       More specifically, each appellant contends that
    the    court    clearly   erred     in     finding   that     he     possessed      the
    specific intent necessary for application of that enhancement.
    In    assessing    whether     a   court    committed    procedural        error     by
    37
    Sherifi was sentenced to concurrent 180-month terms on
    Counts One, Two, and Eleven; a consecutive 60-month term on
    Count Four; and a consecutive 300-month term on Count Eight.
    94
    improperly calculating the advisory Guidelines range, we review
    its    “legal     conclusions    de    novo    and    its   factual        findings   for
    clear error.”          United States v. Lawing, 
    703 F.3d 229
    , 241 (4th
    Cir. 2012).
    The terrorism enhancement has two components.                            The first
    bears    upon     a    defendant’s    offense    level:        If    the    offense    of
    conviction       “is    a   felony    that    involved,     or      was    intended    to
    promote, a federal crime of terrorism,” the applicable offense
    level increases by twelve levels or to a minimum of level 32.
    See USSG        § 3A1.4(a).     The    second    component       of       the   terrorism
    enhancement results in a criminal history category of VI — the
    maximum under the Guidelines.                
    Id. § 3A1.4(b).
            For purposes of
    the enhancement, the phrase “federal crime of terrorism” has the
    meaning specified in 18 U.S.C. § 2332b(g)(5).                       
    Id. § 3A1.4
    cmt.
    n.1.    Thus, a “federal crime of terrorism” is an offense that
    (A) is calculated to influence or affect the conduct
    of government by intimidation or coercion, or to
    retaliate against government conduct; and
    (B) is a violation of [an enumerated statute].
    18     U.S.C.    § 2332b(g)(5).         In     this    case,     the       statutes    of
    conviction for Count One (18 U.S.C. § 2339A) and Count Two (18
    U.S.C. § 956(a)) are among those enumerated in § 2332b(g)(5)(B)
    and, as a result, satisfy the second prong of the definition of a
    “federal crime of terrorism.”            Thus, only the first prong of the
    95
    definition — § 2332b(g)(5)(A)’s specific intent requirement —
    is implicated here.
    As we explained in our series of Chandia decisions, a court
    deciding       whether    to     impose   the    terrorism          enhancement         must
    “resolve       any    factual     disputes      that     it     deems      relevant      to
    application      of    the     enhancement,”     and     then,      if   it     finds   the
    requisite intent, “should identify the evidence in the record
    that supports its determination.”               United States v. Chandia, 
    514 F.3d 365
    , 376 (4th Cir. 2008) (“Chandia I”); see also United
    States    v.     Chandia,      395   F.   App’x.       53,    56    (4th       Cir.   2010)
    (“Chandia II”) (unpublished); United States v. Chandia, 
    675 F.3d 329
    , 331 (4th Cir. 2012) (“Chandia III”).                      In his first appeal,
    we    affirmed       Chandia’s    convictions      but       vacated     his    sentence,
    remanding for fact finding as to whether he possessed the intent
    required   for       application     of   the   terrorism          enhancement.         See
    Chandia 
    I, 514 F.3d at 376
    .               We also vacated and remanded in
    Chandia’s second appeal, explaining that the sentencing court
    had    “again        concluded    that    Chandia       deserved         the    terrorism
    enhancement      . . .    without     resolving     relevant        factual      disputes
    . . . and without explaining how the facts it did find related
    to Chandia’s motive.”             Chandia II, 395 F. App’x. at 54.                      The
    court complied with our mandate in the subsequent resentencing
    proceedings, finally prompting our affirmance in Chandia’s third
    appeal.    See Chandia 
    III, 675 F.3d at 331-32
    .                      Here, abiding by
    96
    our directives in Chandia I and Chandia II, the district court
    resolved the relevant factual disputes and identified, as to
    each appellant, the evidence that supported an individualized
    application of the terrorism enhancement.           See Hassan Sentencing
    Opinion   8   n.5;   Yaghi      Sentencing      Opinion    4    n.5;       Sherifi
    Sentencing Opinion 3 n.5. 38
    Beginning   with   the    sentencing    court’s      determination       that
    Hassan possessed the intent necessary for application of the
    terrorism enhancement, the issue is whether the court erred in
    ruling that Hassan’s actions were “calculated to influence or
    affect the conduct of government by intimidation or coercion, or
    to   retaliate   against      government    conduct.”          See   18     U.S.C.
    § 2332b(g)(5)(A).       The    court    found    that     Hassan     had    built
    relationships with Yaghi and Boyd “based on their shared view of
    Islam, including the goal of waging violent jihad in various
    parts of the world.”          Hassan Sentencing Opinion 8 n.5.                 The
    court explained that Hassan “became part of a loose group of
    conspirators whose goal was to kill non-Muslims, specifically
    38
    Because the appellants’ sentencing proceedings were
    conducted prior to the issuance of our Chandia III decision, the
    district court did not have the benefit of our ruling that “a
    preponderance of the evidence is the appropriate standard of
    proof for establishing the requisite intent for the terrorism
    enhancement.”    
    See 675 F.3d at 339
    .       Being appropriately
    cautious, the court applied the more stringent “clear and
    convincing evidence” standard.
    97
    those they believed were living unjustly in Muslim lands.”                                          
    Id. To further
    support its finding on specific intent, the court
    turned to the record, identifying, in particular, the following:
    that Hassan shared Boyd’s view that jihad imposed an obligation
    on   Muslims      of      “physically          helping          with     the       resistance       or
    fighting against . . . the NATO forces in Afghanistan or Iraq,
    or   anyplace,       really,”       J.A.       1549;          Hassan’s      2007    trip       to   the
    Middle East with Yaghi, for the purpose of finding “those who
    could assist him and defendant Yaghi to join the mujahideen,”
    Hassan    Sentencing        Opinion        8    n.5;          that    Hassan       and   Yaghi,      in
    advance of their 2007 trip to the Middle East, “brandished a
    firearm    to    Daniel      Boyd    in        veiled         reference       to    their      shared
    goals,”   id.;       Hassan’s      role        in        advancing     “jihadist         propaganda
    including the teachings of Anwar al-Awlaki,” as well as Hassan’s
    efforts   to     create      and    disseminate               “his    own    rhetoric”         on   the
    internet, id.; and that Hassan was “trying to offer himself as a
    fighter” and supporting terrorism and extremism by “attempting
    to be a part of it on the battlefield, and supporting those who
    would,”    J.A.      3794.         Premised              on    that    evidence,         the    court
    properly found that Hassan possessed “the motive and intent to
    influence       or     affect       the        conduct           of     the    government           by
    intimidation         or    coercion            or        retaliate       against         government
    conduct.”       See 
    id. 98 In
        its    sentencing           of    Yaghi,      the    district      court       also
    conducted a detailed analysis, finding by clear and convincing
    evidence that he possessed the specific intent necessary for the
    terrorism      enhancement.             The       court   observed     that        Yaghi    had
    initiated a corrupt relationship with Boyd when he “sought out”
    Boyd at an Islamic center in Durham “to learn more about . . .
    Boyd’s time in Afghanistan and presumably to learn more about
    traveling abroad to commit violent jihad.”                             Yaghi Sentencing
    Opinion    4   n.5.        As     further         proof   that    Yaghi’s     conduct       was
    calculated to influence or affect the conduct of government by
    intimidation or coercion, the court relied on his travels in
    2006 and 2007 to the Middle East, each time seeking, in the
    court’s words, “to engage in violent jihad.”                            
    Id. The court
    determined that Yaghi’s communications to Boyd, as well as his
    postings on Facebook, “evidence[d] his intent to wage violent
    jihad and acceptance of radical Islam.”                         
    Id. Moreover, Yaghi’s
    travels   in      the    Middle    East,          his   relationships       with    Boyd    and
    Hassan,    and     his    advocacy           of    violent    jihad   on     the     internet
    “through raps and other postings,” convincingly demonstrated his
    intent    to   participate         in    conduct        calculated     to    influence       or
    affect government.          
    Id. During Yaghi’s
    sentencing hearing, the
    court    observed        that   his      conduct        had   gone    “beyond       words    to
    actions,” and that, despite Yaghi’s “very limited resources, [he
    still went] back over and he trie[d] to go to Israel.”                                     J.A.
    99
    3901.        In    these    circumstances,            application     of    the   terrorism
    enhancement to Yaghi was supported by a preponderance of the
    evidence.
    As with Hassan and Yaghi, the district court made detailed
    factual      findings        with    respect          to   the    application       of     the
    terrorism         enhancement       to     Sherifi.          In     assessing     Sherifi’s
    motives, the court found particular importance in his “return to
    the    United      States    [from       Kosovo]      in   2009     with   the    intent    to
    solicit funds and personnel” to support the mujahideen.                                    See
    J.A. 3853.          The court explained that Sherifi hoped “that he
    would be able to secure farmland from which to launch various
    challenges against military occupation or intervention.”                                   
    Id. Like Hassan
    and Yaghi, Sherifi had developed a relationship with
    Boyd    on    the    basis    of    their       shared      “goal    of    waging    violent
    jihad.”           Sherifi    Sentencing         Opinion      3    n.5.      Sherifi       also
    developed         relationships          with    coconspirator        Subasic       and    the
    notorious Serbian terrorist Asllani.                       The court credited each of
    those relationships, as well as Sherifi’s participation in the
    firearms training conducted in Caswell County, his receipt of
    $15,000 to support the mujahideen, and his “efforts to convert
    [Sergeant] Weeks,” as evidence of Sherifi’s specific intent to
    intimidate, coerce, or retaliate against government.                                See 
    id. Those findings,
    which are not clearly erroneous, support the
    court’s application of the terrorism enhancement to Sherifi.

    2.
    The only other sentencing challenge lodged by Hassan, who
    insists      that     he     was    the    least      culpable      of    the   defendants,
    relates to the district court’s refusal to award him a four-
    level      minimal     participant         reduction        under     Guidelines    section
    3B1.2(a).         We have evaluated Hassan’s contention of error on
    that point, and we are satisfied that the court did not clearly
    err in denying Hassan’s request.                      See United States v. Powell,
    
    680 F.3d 350
    , 358 (4th Cir. 2012).                     In a conspiracy prosecution,
    a minimal participant reduction is not automatically awarded to
    the     least     culpable         conspirator.             To   be      entitled   to      the
    reduction,        a   defendant        must    show    by    a   preponderance         of   the
    evidence that his role in the offense of conviction “makes him
    substantially less culpable than the average participant.”                                  See
    
    id. at 358-59
            (internal      quotation     marks       omitted).       Although
    Hassan      may       have      been       less      active      than      many     of      his
    coconspirators, he has failed to establish that he was a minimal
    participant.          Thus, the court’s ruling to that effect was not
    clearly erroneous, and is not to be disturbed.
    3.
    Turning         to    Yaghi    and      Sherifi’s       contentions       that     their
    sentences were substantively unreasonable, we review for abuse
    of discretion a challenge to the reasonableness of a sentence.
    See United States v. Susi, 
    674 F.3d 278
    , 282 (4th Cir. 2012).
    101
    If, as here, there is “no significant procedural error, then we
    consider the substantive reasonableness of the sentence imposed,
    taking into account the totality of the circumstances, including
    the extent of any variance from the Guidelines range.”                                     
    Id. (internal quotation
    marks omitted).                   As a general rule, “[w]e
    apply a presumption of reasonableness to a sentence within or
    below a properly calculated guidelines range.”                      United States v.
    Yooho Weon, 
    722 F.3d 583
    , 590 (4th Cir. 2013).
    Yaghi maintains that his aggregate sentence of 380 months
    is    unreasonably       harsh,    and    particularly      so     in    light        of    his
    difficult childhood and his peaceful nature.                       Before sentencing
    Yaghi,    the    court     considered      the   contents     of    his        Presentence
    Report, resolved his objections thereto, and properly calculated
    his    advisory     Guidelines       range.         The   court         then    carefully
    evaluated each of the 18 U.S.C. § 3553(a) factors.                        In so doing,
    the    court     weighed     the    nature    and    circumstances             of    Yaghi’s
    offenses of conviction, the need for the sentence imposed, and
    his    history    and     characteristics.          The    court        emphasized         the
    seriousness        of      Yaghi’s       conspiracy       convictions               and    his
    “escalating      contact     with    the   state    criminal       justice           system,”
    explaining that such conduct showed his “disregard for liberty
    and property rights of others,” and his readiness to “resort to
    force.”          See     Yaghi      Sentencing      Opinion        8.           In        these
    circumstances, the court did not act unreasonably, nor did it
    102
    abuse    its   discretion.       Yaghi’s    challenge   to     the      substantive
    reasonableness     of    his    aggregate    sentence     of      380    months   is
    therefore rejected.
    Finally, like Yaghi, Sherifi maintains that his aggregate
    sentence of 540 months is substantively unreasonable.                      Notably,
    Sherifi does not challenge the reasonableness of the consecutive
    sentence of 360 months imposed on his two firearms offenses —
    Counts Four (60 months) and Eight (300 months).                         Rather, he
    contends that, because 360 months for those two convictions is
    adequate punishment and serves as a sufficient deterrent, the
    court    should    not   have     imposed    any   additional           consecutive
    sentences on his conspiracy convictions.                Prior to sentencing
    Sherifi, the court properly calculated the advisory Guidelines
    ranges for each of his offenses of conviction.                          Then, after
    assessing Sherifi’s background and his role in the offenses, the
    court imposed sentences on the conspiracy offenses that were
    substantially below those authorized by statute and recommended
    by the Guidelines.        In these circumstances, the court did not
    abuse its discretion in its sentencing of Sherifi, and we are
    unable    to   disturb   its    sentencing    decisions      on    the    basis   of
    substantive unreasonableness.
    103
    V.
    Pursuant   to   the   foregoing,   we   reject   the    various
    contentions of error presented by the appellants and affirm the
    judgments of the district court.
    AFFIRMED
