    ____________________________________)
    In November 1999, a Riverside County jury found defendant Richard
    Nathan Simon guilty of the first degree murders of Vincent Anes and Sherry
    Magpali (Pen. Code,1 § 187, subd. (a)), the second degree murder of Michael
    Sterling with the personal use of a firearm (ibid.), the rape of Magpali (§ 261,
    subd. (a)(2)), and the kidnapping of Magpali (§ 207, subd. (a)). The jury further
    found true the special circumstance allegations of multiple murder (§ 190.2, subd.
    (a)(3)), that Simon committed Anes‘s murder while engaged in the commission of
    a robbery (former § 190.2, subd. (a)(17)(i), now § 190.2, subd. (a)(17)(A)), and
    that Simon committed Magpali‘s murder while engaged in the commission of a
    robbery, kidnapping, and rape (id., subd. (a)(17)(i)-(iii), now subd. (a)(17)(A)-
    (C)).

    Code.

    The jury was unable to reach a decision at the first penalty trial, so the court
    declared a mistrial. The court then empaneled a new jury, which fixed the penalty
    as death after a second penalty trial.2 The trial court automatically reviewed the
    verdict (§ 190.4, subd. (e)), declined to modify it, and sentenced Simon to death.
    This appeal is automatic. (§ 1239, subd. (b).) For the reasons that follow,
    we affirm the judgment in its entirety.
    I. BACKGROUND
    A. Guilt Phase
    1. Prosecution Evidence
    a. The Killings of Vincent Anes and Sherry Magpali
    On the evening of December 2, 1995, Vincent Anes drove his girlfriend
    Sherry Magpali and their friends Jose and Eugene Menor to a party in Moreno
    Valley. About two hours later, the four left the party, went bowling, and visited
    nearby Taco Bell and Claim Jumper restaurants. Not long after midnight, Anes
    dropped Magpali off near her house and drove the Menor brothers home. Jose
    then observed Anes make a U-turn and travel back toward Magpali‘s residence.
    Around 1:00 a.m., Kenneth Riomales, Jason and John Marianas, and Noah
    Maling drove by Pedrorena Park and saw Anes‘s car in the parking lot. Assuming
    Anes was with Magpali, they did not stop. No more than half an hour later, the
    group returned, checked on the car, and saw a bullet-ridden naked body in the rear
    seat. Although the body‘s face was covered, they suspected it was Anes. Without
    immediately calling 911, the group drove to Anes‘s nearby house and asked
    Anes‘s mother if her son was home. When Anes‘s mother confirmed that he was
    2        Unless otherwise noted, the ―penalty phase‖ refers to this second penalty
    trial.
    2
    not, Riomales called 911 and the group returned to Pedrorena Park with Anes‘s
    mother, brother, and grandfather. Officers met the group within minutes and
    confirmed that Anes was deceased.
    The investigating officers observed that Anes‘s body was missing a ring
    and necklace that he had been wearing earlier that evening. Also missing was a
    large speaker from the car‘s trunk. From the vehicle, investigators collected eight
    9-millimeter shell casings and three 9-millimeter projectiles. They also found a
    jacket holding some of Magpali‘s possessions, including a camera with
    photographs of the couple from that evening‘s party.
    Nearby, officers found Anes‘s underwear and T-shirt on a basketball court.
    The underwear had been cut along the edges of the waist and legs, and the crotch
    had been cut or ripped out. Officers also found torn pieces of Magpali‘s
    undergarments as well as Anes‘s pants, belt, and sock on the roof of a restroom.
    Magpali‘s bra was on the ground near that restroom. Officers recovered 29 latent
    fingerprints from the vehicle and six from the restroom door, but none matched
    any prints within the automated statewide fingerprint identification system.
    Later that morning, officers found Magpali‘s body several miles away on
    the side of Interstate 215 in Sun City, clothed only in jeans and a blouse. Rings
    and a necklace she had been wearing that night were missing. Investigators noted
    blood under her head, and bloodstains on her right hand and jeans. They
    recovered two 9-millimeter shell casings near Magpali‘s body and two 9-
    millimeter projectiles in the dirt beneath her head. Investigators also applied ―tape
    lifts‖ to collect trace evidence that may have adhered to Magpali‘s body and
    clothing.
    Evidence from the victims‘ bodies was later collected at the coroner‘s
    office. Plant material was collected from Anes‘s penis and thigh, but there was no
    indication of sexual assault. Anes‘s autopsy revealed eight gunshot wounds, all
    3
    received within a span of seconds to a minute or two, and from a gun fired
    between three and 18 inches away. In total, five 9-millimeter projectiles were
    removed from Anes‘s body. The other three had been found in the vehicle.
    Magpali‘s autopsy revealed two gunshot wounds to the head, with holes consistent
    with a medium caliber weapon fired from at least 18 to 24 inches away.
    Inconclusive evidence indicated that a third projectile may have grazed Magpali‘s
    face. Toxicology screenings of Anes and Magpali came back negative for alcohol
    and drugs.
    Trace evidence collected from Magpali‘s body included fibers, fingernail
    clippings, swabs from her hands and vagina, and brushings from the hair on her
    head and pubic region. Brushings from her pubic hair, as well as the vaginal
    swab, revealed the presence of sperm. Her jeans and shirt showed possible semen
    stains, in addition to plant material and bloodstains. And although no signs of
    vaginal trauma were detected, Magpali‘s legs had fingertip bruising and scratches
    consistent with being held forcefully. When police later obtained a DNA profile
    from Simon‘s blood sample, it matched the DNA profile exhibited in the sperm
    fraction present on the vaginal swab taken from Magpali‘s body and in the stains
    from the crotch area of her jeans. Simon was the only possible source of the DNA
    samples obtained from those sperm fractions.
    Other trace evidence on Magpali‘s body included red fibers on her jeans
    and on the back of her right leg. These fibers were later determined to be
    consistent with carpet fibers from a 1981 Dodge Colt, which was owned at the
    time by Curtis Williams,3 an associate of Simon‘s. Upon further inspection, this
    3      Williams was arrested in connection with the murders of Anes and Magpali
    on October 6, 1999. He was tried and convicted in separate proceedings and is not
    involved in this appeal.
    4
    vehicle contained two bullet-sized holes, one at the front edge of the glove box
    and one behind it, which tested ―weakly positive‖ for lead. While possible that
    one bullet created both holes, no projectile was found in Williams‘s car.
    Preliminary examination of the recovered projectiles and shell casings from
    both crime scenes showed that all projectiles were probably fired from the same
    gun. The cartridge casings, in particular, exhibited a distinctive impression left by
    the gun‘s firing pin, which was entered into the Federal Bureau of Investigation‘s
    Drugfire system.
    On January 18, 1996 — less than seven weeks after the bodies of Anes and
    Magpali had been discovered — Simon was pulled over for a traffic stop with two
    passengers in the car. All occupants were arrested, the car was impounded, and an
    inventory search revealed a nine-millimeter handgun containing 17 rounds under
    the front passenger‘s seat. Mamie Meeks — Simon‘s front seat passenger —
    testified that earlier that day Simon had driven to a nearby home to pick up a gun
    he had said he needed for protection from ―some of the gang bangers or something
    in San Bernardino he didn‘t get along with.‖ Meeks explained that upon being
    pulled over, Simon gave the gun to Meeks and told her to put it under the seat.
    Simon called Meeks from jail the next day, asking her to claim ownership of the
    weapon. When she refused, Simon became angry and told Meeks that he was
    going to ―fuck her up.‖ This threat prompted Meeks‘s relocation to Nevada for
    several months. Simon was eventually released from custody.
    On May 7, 1996, cartridge casings from the gun found in Simon‘s
    possession were test fired. They matched the impression previously entered into
    the Drugfire system. Further examination revealed that all 10 cartridge casings
    recovered from the Anes and Magpali crime scenes had been fired from that gun.
    5
    b. The Killing of Michael Sterling
    The night of May 25, 1996, officers responding to a call arrived at an
    apartment complex in Moreno Valley. The officers found Vernice Haynes in a
    field across from the complex‘s parking lot, kneeling next to Michael Sterling,
    who had been shot. Sterling was conscious at the time, but he died of a single
    gunshot wound to the chest shortly after paramedics transported him to Riverside
    Hospital.
    Haynes — Sterling‘s then-fiancée — testified that on the night of the
    incident, she and Sterling had been visiting an apartment where Davinna Gentry,
    Sterling‘s cousin, lived with Williams, Gentry‘s boyfriend. Around 8:00 p.m.,
    Simon, joined by Jamal and Raheen Brown, knocked on the door. When Gentry
    opened it, Simon asked if ―Droopy‖ (i.e., Williams) was home. Gentry turned to
    look at Williams, stepping away from the door, at which point Simon entered and
    shook Williams‘s hand.
    Williams introduced Simon to Sterling, the two shook hands, and Simon
    asked Sterling where he was from. After Sterling identified himself as a member
    of the Inland Empire (IE) gang, Simon — who claimed membership in a rival
    gang — became angry, cursing at Sterling. Sterling stood up and lifted his shirt,
    showing that he was unarmed, and told Simon that he had just been released from
    prison and was ―trying to be cool.‖ According to both Gentry and Haynes, Simon
    then told Jamal and Raheen to go get his gun, but they refused. At trial, Jamal
    denied that Simon had made this request.
    Williams attempted to usher Simon outside to talk. Simon responded by
    swinging his fist at Williams and asking why he was hanging out with ―IE.‖
    Gentry asked Simon to leave, as she did not want fighting in her home. Around
    this time, Simon asked Williams if he could use the bathroom, and during his
    absence Gentry told Williams to get Simon out of the house.
    6
    Testimony conflicted on the events that followed. Gentry testified that after
    Simon used the bathroom, he appeared to have calmed down, apologized to
    Sterling and Williams, shook Sterling‘s hand, hugged Sterling, and left the
    apartment with Williams in tow. According to Haynes, Simon cooled down,
    apologized, and hugged Sterling before going to the bathroom. Haynes testified
    further that during Simon‘s absence, she told Sterling that she wanted to leave
    because she was afraid Simon was going to shoot them. But Sterling, worried
    what might happen to Williams, preferred to stay. Haynes also said that when
    Simon exited the bathroom, he apologized again to Sterling, but struck Williams in
    the face with his elbow and yelled at Williams for having Sterling in the house. At
    some point, though, Simon exited the house, and Williams followed.
    Testimony again conflicted on the events that transpired after Simon and
    Williams went outside. According to Haynes, she and Gentry urged Sterling to
    stay inside, but he insisted on leaving to check on Williams. Haynes testified that
    she asked Gentry if there was a back door so that she could go get Sterling‘s
    brothers, but Gentry told her not to leave the house. And as she and Gentry were
    arguing, Haynes said she heard three shots.4 Haynes then testified that Williams
    returned within moments; he appeared to have been in a fight. She ran outside,
    observed Simon and one of his friends running toward Simon‘s car, saw Sterling
    staggering in the field across the street, and ran toward Sterling. Sterling fell to
    the ground and told Haynes that he would be going back to jail.
    When interviewed by police, Gentry‘s version of the events was consistent
    with Haynes‘s testimony in that Gentry said she was inside the apartment when
    she heard gunfire. At trial, however, Gentry claimed that the transcript of her
    4      After the incident, Haynes told officers she had heard four shots.
    7
    taped interview with police was incorrect. Gentry testified instead that after
    Sterling exited the house, Haynes became upset and ran into the bathroom. Gentry
    claimed she then ran out the back door and looked over the gate to see what was
    happening. Gentry said that she could only see shadows, but could tell that
    Sterling was leaning on Simon‘s car, and heard Simon tell Sterling to get off the
    vehicle. When Sterling stood up, she heard two shots together, and a third three to
    four minutes later.
    Jamal Brown also testified at trial, acknowledging that he and his brother
    Raheen accompanied Simon to Gentry‘s apartment that evening. Jamal recalled
    arguments both inside and outside of the apartment, but he testified that Simon
    never told him to go get a gun. Jamal testified further that he did not remember
    how many shots were fired and was not paying attention to what was going on
    immediately before the shooting. When an officer interviewed Jamal on May 31,
    1996, however, Jamal said he had heard two shots. During that interview, Jamal
    also said that Simon had shown him a gun the day of the incident. And although
    Jamal claimed not to have witnessed the events immediately preceding the
    shooting, he told the officer that Simon ―totally shot [Sterling] cold blooded.‖
    When they arrived at the scene, officers found a spent shell casing under a
    stairway across from where Sterling fell. Sterling‘s autopsy showed that he was
    killed by a single gunshot wound to the torso from a .22-caliber bullet traveling
    slightly downward, slightly forward, and from about two feet away. Sterling‘s
    toxicology screening was positive for marijuana and showed a blood-alcohol
    content of 0.10 percent at the time of death.
    On May 26, 1996, officers arrested Simon and searched his home. The
    search was conducted in accordance with a condition of Simon‘s probation for a
    1993 attempted robbery conviction. The condition required that Simon ―[s]ubmit
    [his] person and property under [his] control to search or seizure at any time of the
    8
    day or night . . . with or without a warrant, or probable cause.‖ During the search,
    officers found a .22-caliber handgun under Simon‘s mattress, a box of CCI brand
    ammunition, and a clip loaded with several brands of bullets. Investigators later
    determined that the shell casing recovered from the Sterling crime scene was fired
    by this gun, and the projectile from Sterling‘s body could have been fired by this
    gun.
    2. Defense Evidence
    The defense theory of the Anes/Magpali murders was that Williams alone
    was responsible for killing the two teens. In support of this theory, the defense
    presented evidence that Williams would have had access to the murder weapon
    during the relevant time period. Defense witnesses testified that on January 18,
    1996, when Simon was stopped for the traffic violation, he had gone with Meeks
    to a residence on Fay Avenue to pick up the gun. Witnesses testified further that
    Williams regularly visited a friend at that house.
    As to the Sterling homicide, the defense argued that the offense amounted
    to less than first degree murder based in part on character evidence suggesting
    Sterling had a propensity for violence. Haynes, Sterling‘s fiancée at the time,
    testified that Sterling had been in prison for assaulting another man, and that he
    had been in jail on other occasions.
    B. Penalty Phase
    At the penalty phase, the prosecution relied on the circumstances of the
    crimes and Simon‘s previous misconduct as evidence in aggravation supporting
    imposition of the death penalty. The prosecution presented testimony relating to
    the circumstances of the convicted offenses, as well as victim impact evidence on
    behalf of Magpali, Anes, and Sterling. As to previous misconduct, the prosecution
    introduced evidence that jail personnel had found shanks in Simon‘s cell on two
    9
    occasions. The prosecution also introduced evidence of a letter, purportedly
    written by Simon while in jail, to his cousin Terri Richardson. The letter, which
    referenced committing possible acts of violence against other inmates, was
    admitted to show Simon‘s motive or intent for possessing a shank on the first
    occasion. The letter stated, for example, ―I‘ll hurt one of these fools . . . . I‘m
    tired of these punk ass fools in here . . . .‖ It continued, ―I‘m not going to take this
    shit too much longer. . . . I‘m going to lay one of they ass out. I‘ll beat the shit
    out of one of these fools.‖ The letter was signed, ―Still you cuz, Nate.‖
    The defense presented evidence in mitigation. In making the case for
    mitigation, the defense focused on Simon‘s psychological background, including
    testimony from relatives about Simon‘s childhood and expert testimony discussing
    organic brain damage. Simon‘s mother, who eventually became a police officer,
    testified that she had been in several abusive relationships during Simon‘s
    formative years. One of those relationships was with her patrol sergeant, who
    became physically abusive toward both her and Simon. On one occasion, this man
    punched Simon for teasing the man‘s youngest son. On another, the man tied
    Simon‘s hand to a door with a belt and beat him severely. When Simon was in his
    late teens, he was knocked unconscious during a fight at a park in Compton.
    About a year later, Simon moved from California to Michigan to live with
    relatives. While there, he suffered a gunshot wound to the head, causing him to
    lose sight in his left eye. After being hospitalized for his injuries, Simon returned
    to California. His cousin Richardson testified that Simon seemed different when
    he came back from Michigan. But Simon was supportive of Richardson during
    her pregnancy. Another of Simon‘s female relatives, his half sister, testified that
    she considered Simon a positive role model who had discouraged her from
    engaging in criminal behavior.
    10
    The defense also offered testimony from two medical experts. The first,
    Dr. David Fukuda, treated Simon during the time he was incarcerated pending
    trial. Dr. Fukuda prescribed medication to control Simon‘s seizures and ordered
    skull X-rays and a computerized axial tomography (CAT) scan, which revealed
    bullet fragments lodged in Simon‘s right nasal bone and left eye socket. The CAT
    scan also revealed encephalomalacia of the right frontal lobe with deformity of the
    overlying cranium consistent with Simon‘s previous surgery to treat the gunshot
    wound he sustained in this area. The second expert, neurologist Dr. Kenneth
    Nudleman, examined Simon prior to trial. Dr. Nudleman reviewed Simon‘s
    medical records and ordered additional neurological testing. From these sources,
    Dr. Nudleman concluded that Simon suffered from significant organic brain
    damage primarily to the right frontal lobe and, to a lesser extent, the left frontal
    lobe. He found roughly 20-25 percent of Simon‘s right frontal lobe was missing.
    This part of the brain, Dr. Nudleman explained, is involved with impulse function
    and anger control.
    During rebuttal, the prosecution introduced an undated and unaddressed
    letter that had been enclosed in the Richardson letter and was purportedly directed
    toward Simon‘s wife, Keisia. The letter, introduced to rebut evidence of Simon‘s
    good character, contained threatening and explicit language. It read, for instance:
    ―If I can‘t get you, I‘m getting the closest thing to you, bitch. . . . [¶] I‘m going to
    get you, bitch. . . . I‘m the one to be scared of. . . . [¶] I‘m already a dead man
    walking, . . . so can‘t shit you say or do hurt me. But I can do a whole lot to hurt
    you. . . . [¶] You are now considered road kill, bitch, and if you run from it, your
    best friend takes your place.‖ The letter was signed, ―Until doomsday, yours that
    is; [¶] Nate, (rides again).‖
    11
    II. DISCUSSION
    A. Issue Affecting Both Phases
    1. Stun Belt
    Simon claims the trial court erred by requiring him to wear a remote-
    controlled stun belt as a security measure during the guilt and penalty phases.5
    We disagree.
    a. Background
    On September 13, 1999, the first day of jury selection, defense counsel
    requested that ―no chains, shackles, cuffs [or] anything of that sort be worn by the
    defendant during the course of the trial.‖ Defense counsel stated that he had been
    told Simon was wearing a Remote Electronically Activated Control Technology
    (REACT) stun belt that day, an arrangement defense counsel opposed unless the
    court could provide adequate justification. Defense counsel also complained that
    the belt was placed in such a manner — near Simon‘s left hip — that some jurors
    might be able to notice it.
    The trial court granted the motion that Simon be unshackled. But the court,
    relying on a series of incidents described by the bailiff, denied Simon‘s request to
    have the stun belt removed. At the court‘s behest, the bailiff detailed the
    following incidents on the record: in June 1996, Simon had a fight with another
    inmate; less than a year later, in April 1997, jail personnel found a shank in
    Simon‘s cell; in July 1998, Simon refused to obey a deputy‘s order, and jail
    personnel found excess food in his cell; in September 1998, Simon refused to
    return to his cell during a lockdown, and jail personnel found two plastic shanks in
    5       A stun belt is a device worn around the waist that delivers an incapacitating
    electric shock when activated by a court security officer. (See People v. Mar
    (2002) 
    28 Cal.4th 1201
    , 1204 (Mar).)
    12
    Simon‘s cell; in August 1999, jail personnel found feces stored in a container in
    Simon‘s cell, along with cleaning products; and that same month, Simon
    threatened a new deputy.
    In denying Simon‘s motion, the trial court expressed particular concern
    about the shanks and incidents of fighting. The court also noted that it had
    inquired into why the feces and cleaning supplies were significant and learned
    from the bailiff, as well as from another deputy who was present during their
    discussion, that these items are commonly used in making explosives.
    Defense counsel next indicated that Simon was uncomfortable because the
    position of the stun belt prevented him from leaning back in his chair. Defense
    counsel also requested that the belt be placed on Simon‘s right side to make it
    more difficult for the jury to notice its presence. The trial court asked whether the
    belt could be worn on either side, to which the bailiff responded that the belt could
    only be placed on the left side. The court then asked if the inability to lean back is
    a typical problem with the belt, and the bailiff explained that an extra cushion
    positioned on the right side usually solved this problem.
    Defense counsel interjected to raise another concern: Simon had a prior
    injury to his left hip area that was causing him discomfort. The cushion, defense
    counsel explained, did not improve Simon‘s ability to lean back, and he was
    worried Simon would appear uncomfortable in front of the jury. Defense counsel
    also argued that Simon should not have to wear the stun belt at all because there
    had been no indication that Simon was a flight risk, and because searching him
    prior to his entering the courtroom would alleviate any concerns about his bringing
    in weapons.
    The trial court declined to change its positon. The court explained that its
    primary concern was not necessarily that Simon would bring a shank into the
    courtroom or attempt to escape. Rather, the concern was that the shanks, fights,
    13
    and bomb-making materials indicated to the court that Simon was a danger to
    others. The court noted further: ―When we bring 75 good citizens into the
    courtroom, I think we need to do everything we can to make sure that they are
    protected, as well as our own staff and counsel. And I think that . . . some kind of
    restraint is appropriate.‖ The court also prepared a minute order, dated September
    13, 1999, which read: ―Oral Motion By DEFENSE regarding NO RESTRAINTS
    ON DEFT DURING TRIAL is called for hearing. [¶] Motion Granted. [¶]
    Defendant to remain unshackled during trial. [¶] Motion denied as to React Belt.
    Defendant to wear React Belt during trial.‖
    Simon renewed his objection to wearing the stun belt on July 16, 2001, at
    the start of the penalty phase. Defense counsel noted the absence of any incidents
    during the three and a half month trial of the guilt phase, and during the year and a
    half since a mistrial had been declared at the first penalty trial. Defense counsel
    acknowledged that the stun belt was ―less obtrusive and noticeable than shackles
    or something of that sort,‖ but he added that the stun belt was still a ―fairly
    obtrusive item‖ and could be seen if Simon were not wearing a jacket.
    The trial court solicited information from a sheriff‘s deputy, who reminded
    the court of incidents with the shanks and the fight involving another inmate. The
    deputy also mentioned that Simon had claimed to be a member of the Crips gang
    and had been verbally aggressive toward deputies on several occasions since 1998
    and as late as 2001. The deputy noted further that Simon had written a letter in
    1997 containing racial slurs and mentioning a possible attempt to assault a
    Hispanic inmate. Finally, the deputy opined that because Simon had already been
    convicted, he had nothing to lose. Simon was therefore considered ―a very high
    security risk‖ who was being housed accordingly.
    Defense counsel argued that neither the charges brought against Simon nor
    the nature of his crimes could alone justify requiring him to wear the stun belt.
    14
    Further, defense counsel objected to the vagueness of the deputy‘s references to
    Simon‘s alleged verbal aggression toward his jailers. He questioned the reliability
    of the information and noted that the deputy was not under oath. The deputy
    interjected at that point, explaining that an incident had happened that morning.
    The trial court then asked for input from the prosecutor, who argued that
    Simon had exhibited violent tendencies by taking the time to manufacture
    weapons in his cell, and that the court should ensure the safety of the courtroom by
    requiring Simon to wear the stun belt. The prosecutor also noted the possibility of
    using another type of stun belt that is worn on the leg rather than the waist. A
    deputy explained that this device is called a Band-It, but it was being used at
    another facility so it was not available that day. The deputies would need two
    days‘ lead time in order to obtain it.
    After reflecting on the views expressed by counsel and the relevant
    information, the trial court ruled that Simon should continue to wear the stun belt
    for the penalty phase. The court agreed with defense counsel that verbal
    aggressiveness, the threats in the letter, and the nature of the charges and possible
    punishment did not warrant use of the stun belt. The court also agreed that Simon
    was unlikely to bring a weapon to court. Nonetheless, Simon‘s previous
    possession of shanks demonstrated a potential willingness to commit violence.
    Observing that only one or two armed deputies would be present, the court
    reiterated its concern for the safety of the more than 90 people that would be in the
    courtroom. The court also stated it would ―certainly direct the deputies at this
    time to put [the stun belt] on in such a way that it is as unobtrusive as possible.‖
    In this vein, the court asked again whether the belt could be put on Simon‘s right
    side. Although the deputies had previously told the court this was not possible,
    they now informed the court that the belt could in fact be placed on Simon‘s right
    side for the penalty phase. The court also asked the deputies to look into the
    15
    possibility of obtaining the Band-It, but defense counsel did not press the matter
    further.
    b. Legal Standard
    A trial court has broad power to maintain courtroom security and orderly
    proceedings, and its decisions on these matters are reviewed for abuse of
    discretion. (People v. Bryant, Smith and Wheeler (2014) 
    60 Cal.4th 335
    , 389
    (Bryant, Smith and Wheeler).) That discretion, however, must yield to principles
    of due process. (Ibid.) To that end, we have held that physical restraints of any
    kind are inappropriate in the courtroom while the jury is present, unless there is a
    manifest need for such restraints. (People v. Duran (1976) 
    16 Cal.3d 282
    , 290-
    291 (Duran).) This ―manifest need‖ standard applies equally to use of a stun belt.
    (Mar, 
    supra,
     28 Cal.4th at pp. 1218-1220.) In determining whether there is a
    manifest need to restrain the defendant, courts consider several factors, including
    evidence that the defendant poses a safety or flight risk or is likely to disrupt the
    proceedings. (Bryant, Smith and Wheeler, at p. 389.) The use of physical
    restraints in the absence of a record showing of violence, a threat of violence, or
    other nonconforming conduct is an abuse of discretion. (Duran, at p. 291.)
    No formal hearing is required. But when the use of restraints is based on
    conduct of the defendant that occurred outside the presence of the trial court,
    sufficient evidence of such conduct must be presented on the record so that the
    court may make its own determination of the nature and seriousness of the conduct
    and whether there is a manifest need for such restraints. (Mar, supra, 28 Cal.4th
    at p. 1221.) The court may not, we have emphasized, merely rely on the judgment
    of law enforcement or court security officers or the unsubstantiated comments of
    others. (Ibid.) The court‘s determination must be based on facts, not rumor or
    innuendo. (People v. Cox (1991) 
    53 Cal.3d 618
    , 652.) And even when the record
    16
    establishes a manifest need for restraints, the restraint imposed must be the least
    obtrusive or restrictive one that would be effective under the circumstances.
    (Duran, supra, 16 Cal.3d at p. 291; Mar, at p. 1226.)
    c. Analysis
    Simon argues first that the trial court abused its discretion by applying a
    lower standard at the guilt phase to reject his request to have the stun belt
    removed. According to Simon, the court improperly applied something akin to a
    ―good cause‖ standard — rather than the required manifest need standard. In
    support of his contention, Simon points to the fact that the court, after sustaining
    Simon‘s objection to being shackled, appears to have treated the stun belt issue as
    a separate matter. Simon also points to the trial court‘s statement that use of the
    stun belt was ―appropriate‖ (instead of ―necessary‖) as suggesting that it applied
    something lower than the manifest need standard prescribed by Duran and Mar.
    But Simon‘s guilt phase and penalty phase trials predated Mar. In that
    case, we held for the first time that the record must demonstrate a manifest need
    — rather than mere good cause — for imposition of a stun belt. And even if the
    trial court‘s use of the word ―appropriate,‖ rather than ―necessary,‖ may suggest it
    applied a lower standard, the record as a whole establishes that the manifest need
    standard was met. (See People v. Mayfield (1993) 
    5 Cal.4th 142
    , 196 [―The record
    of the hearing as a whole persuades us, however, that even though the court, in
    isolated instances, misstated the applicable standard, it nevertheless applied the
    proper concept‖].)
    The record shows that, at the guilt phase, the trial court based its decision
    on Simon‘s violent behavior in custody and his potential danger to others in the
    courtroom. In particular, the court‘s decision was based on Simon‘s fight with
    another inmate; the discovery, on two different occasions, of shanks in Simon‘s
    17
    cell; the discovery of feces and cleaning products, which Simon had stored in a
    container for possible use as an explosive; and Simon‘s threat against a corrections
    deputy. The court stated on the record that these incidents showed that Simon was
    a potential danger to jurors, court staff, and counsel. Likewise, at the penalty
    phase, the court relied on Simon‘s previous possession of shanks as evidence of
    his potential readiness to commit violence.
    The trial court‘s findings and analysis were sufficient to show a manifest
    need for the stun belt. As we have held previously, a defendant‘s disruptive
    behavior while in jail, including possession of shanks or explosives, justifies the
    imposition of restraints. (See, e.g., People v. Wallace (2008) 
    44 Cal.4th 1032
    ,
    1050 [evidence of fighting with inmates and possession of illegal razors]; People
    v. Lewis and Oliver (2006) 
    39 Cal.4th 970
    , 1032 [defendant attacked another
    inmate and threatened to kill deputies]; People v. Combs (2004) 
    34 Cal.4th 821
    ,
    838 [defendant possessed two shanks in jail and threatened jail deputies]; People
    v. Alvarez (1996) 
    14 Cal.4th 155
    , 190-192 [fights with inmates, threatening
    deputies, and possession of weapons and an explosive device].)
    In addition, the record shows the trial court was ―aware of its obligation
    [under Duran] to make its own determination on the need for restraints, and not
    simply defer to the wishes of the prosecutor or courtroom security personnel.‖
    (Bryant, Smith and Wheeler, supra, 60 Cal.4th at p. 391.) The court explained that
    it needed to state on the record the reasons justifying resort to the stun belt and
    identified the specific incidents supporting use of that restraint. The court further
    demonstrated an understanding of its duty under the Duran line of cases by noting
    at the start of the penalty phase that the mere fact of Simon‘s conviction and
    potential sentence could not justify imposition of the stun belt. (See Duran, supra,
    16 Cal.3d at p. 293 [―we cannot condone physical restraint of defendants simply
    because they are prisoners already incarcerated on other charges or convictions‖];
    18
    see also People v. Hawkins (1995) 
    10 Cal.4th 920
    , 944 [―We agree with defendant
    that his record of violence, or the fact that he is a capital defendant, cannot alone
    justify his shackling‖].) Instead, the court relied on Simon‘s history of possessing
    shanks, a circumstance we have held sufficient to show a manifest need for
    restraints. (See People v. Combs, supra, 34 Cal.4th at p. 838.)
    Simon contends that the incidents of violence supporting the trial court‘s
    decision were not described in sufficient detail because the bailiff had no personal
    knowledge of the events. This argument is unavailing. We have found that a trial
    court can base its decision to restrain a defendant on reliable facts provided by law
    enforcement or counsel. (See, e.g., People v. Wallace, supra, 44 Cal.4th at
    pp. 1049-1050 [upholding trial court‘s imposition of restraints where deputy
    represented that defendant had 16 rules violations while in jail]; People v. Medina
    (1995) 
    11 Cal.4th 694
    , 731 [prosecutor‘s representations of facts, made without
    objection or rebuttal by defendant, properly supported trial court‘s ruling to
    impose restraints].) Unlike in People v. Cox, 
    supra,
     53 Cal.3d at page 651, where
    the trial court‘s decision was based on ― ‗rumors floating through the jail‘ ‖ about
    an escape attempt, the court here grounded its decision on incidents that had
    already occurred and for which the bailiff provided specific dates. The court also
    explained that it had inquired further into the significance of the feces and
    cleaning supplies, learning that these items could be used in tandem to create
    explosives. Moreover, as in People v. Medina, 
    supra,
     11 Cal.4th at page 731,
    Simon did not dispute his possession of the shanks and bomb-making components,
    or his altercation with another inmate. At the penalty phase, defense counsel did
    object on vagueness grounds to the deputy‘s references to Simon‘s verbal
    aggressiveness, but the court did not base its decision thereon. To the contrary,
    the court explicitly stated that verbal aggression would not warrant imposing the
    19
    stun belt on Simon. The court based its rulings at both the guilt and penalty
    phases on uncontested facts related by the bailiff and sheriff‘s deputies.
    Simon argues further that the trial court abused its discretion because it did
    not consider whether the stun belt was the least restrictive or obtrusive restraint
    under the circumstances. Underlying Simon‘s argument is his claim that the trial
    court failed to consider the potential psychological consequences of his wearing a
    stun belt and the physical effects from electric shock on individuals with certain
    medical conditions — considerations we discussed extensively in Mar. (See Mar,
    
    supra,
     28 Cal.4th at pp. 1225-1230.) But we expressly stated that our discussion
    of these factors was included as guidance for ―future trials.‖ (Id. at p. 1225, italics
    added.) Because the proceedings below were held prior to our decision in Mar,
    the trial court was ―not required to foresee and discuss each of the concerns
    detailed in that opinion.‖ (People v. Lomax (2010) 
    49 Cal.4th 530
    , 562.) The trial
    court, therefore, cannot be said to have abused its discretion. (See Bryant, Smith
    and Wheeler, supra, 60 Cal.4th at p. 391.)
    Simon‘s broader argument also founders. The record shows the trial court
    was deliberate in its choice of restraint, ruling that although the stun belt was
    appropriate, shackles were not. And defense counsel later conceded that the stun
    belt was less obtrusive than traditional shackles. The court also explained that it
    was not necessarily concerned Simon would bring in weapons or escape; rather, its
    concern was that Simon‘s tendency toward violence posed an undue risk to those
    in attendance. Thus, simply searching Simon before he entered the courtroom, as
    defense counsel had recommended, was not enough to protect the public in the
    court‘s view.
    The record further indicates the trial court attempted to make the device as
    comfortable and unobtrusive as possible. After Simon complained before the guilt
    phase that the stun belt was causing discomfort to his left hip area, the court
    20
    allowed an extra cushion for Simon and inquired about having the belt
    repositioned. Although Simon indicated that the pillow did not ease his
    discomfort, when defense counsel objected to the belt at the start of the penalty
    phase, he did not argue that Simon had actually been uncomfortable during the
    guilt phase — defense counsel noted only that a pillow had to be provided to
    alleviate Simon‘s discomfort. The court also directed the deputies to place the belt
    on Simon ―in such a way that it is as unobtrusive as possible.‖ The court then
    asked them to look into obtaining the Band-It — a stun belt worn on the leg, rather
    than the waist — for the remainder of the penalty phase. This device was not
    available, however, because it was being used at another facility. But the court did
    ask the deputies to investigate obtaining the device, and Simon never raised the
    issue again. Contrary to Simon‘s assertions, the court considered less restrictive
    security measures and implemented available procedures to address his discomfort
    and mitigate the stun belt‘s obtrusiveness.
    We therefore hold that the trial court‘s decision to restrain Simon with the
    stun belt was not an abuse of discretion.
    B. Guilt Phase Issues
    1. Warrantless Blood Draw
    Simon argues that two blood samples taken following his arrest for the
    Sterling homicide were illegally obtained. As a result, Simon contends, the DNA
    evidence extracted from the second sample — evidence that connected Simon to
    the Anes and Magpali murders — ought to have been suppressed. We find any
    error harmless.
    a. Background
    Simon was arrested in connection with the Sterling homicide between 3:30
    and 4:00 a.m. on May 26, 1996. A few hours after Simon had been arrested and
    21
    transported to the local police station, at approximately 7:00 a.m., investigating
    officers arranged for a nurse to draw a sample of Simon‘s blood. Several hours
    after the first blood draw, a nurse took a second blood sample. Hair and saliva
    samples were also taken. The second blood sample was used to create a DNA
    profile that was compared to DNA samples taken from the scene of the Anes and
    Magpali murders. The police did not obtain a warrant for either blood sample.
    Simon moved to suppress all evidence involving the blood samples,
    including the results of DNA testing, on grounds that the samples had been
    obtained without a warrant and absent any exception to the warrant requirement.
    In opposing the motion, the prosecution explained that at the time the samples
    were taken, Simon was on probation for a 1993 attempted robbery conviction.
    According to the prosecution, then, the taking was authorized by a probation
    search condition — which the investigating officers knew of at the time — that
    required Simon to ―[s]ubmit your person and property under your control to search
    or seizure at any time of the day or night . . . with or without a warrant, or
    probable cause.‖ The prosecution argued in the alternative that the first blood
    sample, drawn within hours of Simon‘s arrest for the Sterling homicide, was
    needed to determine Simon‘s level of intoxication and state of mind at the time of
    the homicide, and that the dissipation of such evidence over time created an
    exigent circumstance that excused the warrant requirement. Finally, the
    prosecution maintained that Simon‘s DNA profile, which was derived from the
    second blood sample, would inevitably have been discovered given that the first
    sample had been obtained lawfully and police already had evidence linking Simon
    to the Anes/Magpali murders at the time of Simon‘s May 26 arrest.
    Following a hearing, the trial court denied Simon‘s motion to suppress. In
    the court‘s view, the probation search term ―does include the right to search the
    person, . . . including even the bodily fluids, hair, [and] various other samples that
    22
    might be taken.‖ The court therefore concluded that the blood draws, which the
    parties later agreed had been conducted in a ―legally and medically prescribed
    manner,‖ were lawful. Simon contends that this ruling was erroneous and that
    admission of the DNA evidence derived from the warrantless blood draws violated
    his rights to be free of unreasonable searches and seizures under the federal and
    California constitutions.
    b. Legal Standard
    A defendant may move to suppress evidence under section 1538.5 on
    grounds that a search without a warrant was unreasonable. A warrantless search is
    presumptively unreasonable, and the prosecution bears the burden of
    demonstrating a legal justification for the search. (People v. Redd (2010) 
    48 Cal.4th 691
    , 719.) In reviewing a trial court‘s ruling on a motion to suppress, we
    defer to the trial court‘s factual findings, express or implied, where supported by
    substantial evidence. (Ibid.) And in determining whether, on the facts so found,
    the search was reasonable for purposes of the Fourth Amendment to the United
    States Constitution, we exercise our independent judgment. (Ibid.)
    c. Analysis
    We have not addressed whether a general probation search condition, such
    as the one to which Simon was subject, authorizes a warrantless, nonconsensual
    blood draw. (Cf. People v. Jones (2014) 
    231 Cal.App.4th 1257
    , 1266 [postrelease
    community supervision search condition, which provided that ― ‗[t]he person, and
    his or her residence and possessions, shall be subject to search at any time of the
    day or night, with or without a warrant . . . ,‘ ‖ encompassed warrantless blood
    draws].) And we need not do so here: even if the May 26 blood draws exceeded
    the scope of Simon‘s probation search condition, the trial court‘s decision not to
    23
    suppress the DNA evidence derived from those blood draws was harmless in this
    case.
    At the time of Simon‘s arrest on May 26, 1996, investigators had
    significant evidence linking him to the murders of Anes and Magpali. Five
    months earlier — in January — Simon had been pulled over and found in
    possession of a nine-millimeter handgun. By May 7 — almost three weeks before
    Simon‘s arrest for the Sterling murder — investigators had determined that this
    particular gun was the source of the 10 cartridge casings found near the bodies of
    Anes and Magpali. In addition, the officers who ordered the blood draw knew that
    Simon had recently shot and killed another person (i.e., Sterling).
    So when Simon‘s blood was drawn, he was in custody for the Sterling
    homicide, and the police had key evidence tying him to the murders of Anes and
    Magpali — namely, Simon had been found in possession of the murder weapon.
    Given this evidence, and the fact Simon was lawfully in custody for a separate
    homicide, the trial court would have, to a near certainty, ordered a subsequent
    blood sample be taken from Simon even if the initial samples had been drawn
    unlawfully. That new sample would have disclosed Simon‘s DNA profile — the
    very information used against him at trial. Any error in not suppressing the blood
    samples was therefore harmless. (See People v. Siripongs (1988) 
    45 Cal.3d 548
    ,
    569 [finding any error in not suppressing warrantless blood draw ―harmless‖
    because ―even had the [trial] court ruled the blood sample unlawfully drawn,
    [probable cause existed so] it could have later ordered a new blood sample to be
    drawn‖].)6
    6       Following oral argument in this case, the United States Supreme Court held
    that the search-incident-to-arrest doctrine does not justify law enforcement‘s
    failure to obtain a warrant before drawing the blood of someone lawfully arrested
    (footnote continued on next page)
    24
    2. Severance
    Simon argues that the trial court committed reversible error in denying his
    motion to sever the Anes/Magpali counts from the Sterling counts. We find no
    error.
    a. Background
    Before the guilt phase, Simon moved to sever the Anes/Magpali charges
    (counts 1-5)7 from the Sterling charges (counts 6-7),8 and made several arguments
    for why joinder of the offenses would be ―so prejudicial that it would deny [him] a
    fair trial.‖ First, Simon argued that evidence from each incident was not cross-
    (footnote continued from previous page)
    on suspicion of drunk driving. (See Birchfield v. North Dakota (June 23, 2016,
    No. 14-1468) ___U.S.___ [
    2016 WL 3434398
    ].) Warrantless blood draws, in
    other words, cannot be justified as a search incident to arrest. This holding does
    not change the result here because, we conclude, any error in not suppressing the
    blood samples was harmless. And we need not consider the extent, if any, to
    which a search incident to arrest differs from a probation search.
    7       Count 1 charged Simon with the murder of Anes. It also alleged that he
    used a firearm during the murder and that the murder was committed during the
    commission of a robbery. Anes‘s missing jewelry and speaker were the basis for
    the robbery allegation. Count 2 charged Simon with the murder of Magpali. It
    also alleged that he used a firearm during the murder and that the murder was
    committed during the commission of a robbery, kidnapping, and rape. Magpali‘s
    missing jewelry was the basis for the robbery allegation. Count 3 charged Simon
    with the rape of Magpali. It also alleged that he used a deadly weapon during the
    rape and that the rape was committed during the course of a kidnapping. Count 4
    charged Simon with kidnapping Magpali. It also alleged that he used a firearm
    during the commission of the kidnapping. Count 5 charged Simon with
    possession of a firearm — on or about December 3, 1995 — after previously being
    convicted of attempted robbery.
    8      Count 6 charged Simon with the murder of Sterling. It also alleged that he
    used a firearm during the murder. Count 7 charged Simon with possession of a
    firearm — on or about May 25, 1996 — after previously being convicted of
    attempted robbery.
    25
    admissible because the events were unrelated. Second, he contended that evidence
    from both incidents was highly inflammatory. Simon noted that the Anes/Magpali
    incident involved the killing of two teenagers, one of whom was sexually
    assaulted, and the Sterling shooting appeared to be gang related. Third, Simon
    claimed that the evidence supporting the Sterling charges was relatively weak
    compared to the ―strong‖ Anes/Magpali charges. And fourth, Simon argued that
    because the Sterling charges did not independently give rise to special
    circumstances warranting the death penalty, their joinder with the Anes/Magpali
    capital offenses would be highly prejudicial.
    Following a hearing, the trial court denied Simon‘s motion to sever. The
    court offered the following explanation: ―it does appear to me that there is some
    potential prejudice. However, I don‘t think that that prejudice outweighs the
    benefits. And so without saying more, I‘m going to deny the motion.‖
    b. Legal Standard
    Section 954, in relevant part, permits the joinder of ―two or more different
    offenses of the same class of crimes or offenses.‖ Joinder is ordinarily favored
    because it avoids the increased expenditures of funds and judicial resources that
    may result from separate trials. (See Alcala v. Superior Court (2008) 
    43 Cal.4th 1205
    , 1220 (Alcala).) Joinder, therefore, ―is the course of action preferred by the
    law.‖ (Ibid.) Nonetheless, a trial court has discretion to sever properly joined
    charges in the interest of justice and for good cause. (§ 954; see People v.
    Merriman (2014) 
    60 Cal.4th 1
    , 37.)
    Our review proceeds in two steps. First, we examine whether, in light of
    the information available at the time, the trial court abused its discretion in
    denying the severance motion prior to the guilt phase. (People v. Mendoza (2000)
    
    24 Cal.4th 130
    , 161 (Mendoza).) Where, as here, the statutory requirements for
    26
    joinder are met,9 a defendant must make a ―clear showing of prejudice‖ to
    establish that the trial court abused its discretion in denying the motion. (Id. at
    p. 160.) A defendant seeking severance of properly joined charged offenses must
    make a stronger showing of potential prejudice than would be necessary to
    exclude evidence of other crimes in a severed trial. (People v. Soper (2009) 
    45 Cal.4th 759
    , 774.)
    Second, even if the trial court‘s ruling was proper as a matter of state law,
    we will reverse the judgment if the defendant shows that joinder of the charges
    actually resulted in ―gross unfairness‖ amounting to a denial of due process during
    the guilt phase. (Mendoza, 
    supra,
     24 Cal.4th at p. 162.)
    c. Analysis
    i. Abuse of Discretion
    We analyze severance questions by considering a case‘s specific facts.
    Whether a trial court abused its discretion in denying severance depends, thus, on
    the particular circumstances of each case. (People v. Sandoval (1992) 
    4 Cal.4th 155
    , 172.) The factors we consider are as follows: (1) whether the evidence
    relating to the various charges would be cross-admissible in separate trials,
    (2) whether any of the charges are unusually likely to inflame the jury against the
    defendant, (3) whether a weak case has been joined with a strong case or with
    another weak case, and (4) whether one of the charges is a capital offense or the
    joinder of the charges converts the matter into a capital case. (People v. Elliott
    (2012) 
    53 Cal.4th 535
    , 551.)
    9      Because murder, rape, robbery, and kidnapping are all assaultive crimes
    against the person, the Anes/Magpali incident and the Sterling incident both
    involved ―offenses of the same class of crimes,‖ thus satisfying the statutory
    requirements for joinder under section 954. (See People v. Ramirez (2006) 
    39 Cal.4th 398
    , 438-439; People v. Rhoden (1972) 
    6 Cal.3d 519
    , 524-525.)
    27
    We find that Simon has failed to establish a ―clear showing‖ of potential
    prejudice under these factors. (Mendoza, 
    supra,
     24 Cal.4th at p. 160.) So he
    cannot show the trial court abused its discretion in denying his motion to sever.
    (a) Cross-admissibility
    The prosecution conceded below that evidence for the separate incidents
    would not be cross-admissible in separate trials. Although cross-admissibility of
    evidence is often an independently sufficient condition justifying a trial court‘s
    denial of severance, it is not a necessary one. (See Alcala, 
    supra,
     43 Cal.4th at
    pp. 1221-1222, 1227.) In the absence of cross-admissibility, we turn to the
    remaining factors to assess whether the trial court abused its discretion. (See
    People v. McKinnon (2011) 
    52 Cal.4th 610
    , 630-631 (McKinnon).)
    (b) Particularly Inflammatory Charges
    Simon has not made a clear showing of potential prejudice under this
    factor. Comparing the two sets of charges, it appears plain that the Anes/Magpali
    murders were more likely to inflame the jury‘s passions. The victims, though no
    longer minors, were still teenagers. One of them was shot eight times, while the
    other was kidnapped from the scene and raped before being shot twice in the head.
    The facts of the gang-related Sterling murder, though far from innocuous, were
    unlikely to evoke the same emotions as the Anes/Magpali crimes.
    Indeed, courts have recognized that sex crimes can be quite inflammatory,
    especially when they involve young victims. (See Williams v. Superior Court
    (1984) 
    36 Cal.3d 441
    , 452 (Williams) [―It is true that the present case does not
    involve the ‗highly inflammatory‘ issue of sex crimes against children‖],
    superseded by statute on another ground as stated in Alcala, 
    supra,
     43 Cal.4th at
    p. 1229, fn. 19.) In Coleman v. Superior Court (1981) 
    116 Cal.App.3d 129
    (Coleman), a Court of Appeal case on which the parties rely, the defendant was
    28
    charged with sex crimes against an 11-year-old child and a 13-year old child. The
    appellate court deemed it prejudicial to join these charges with a more serious
    murder charge, in part, because sexual crimes against children are ―highly
    inflammatory‖ and might have ―a very serious prejudicial effect upon the jury.‖
    (Id. at p. 139.)
    But the animating concern underlying this factor is not merely whether
    evidence from one offense is repulsive, because repulsion alone does not
    necessarily engender undue prejudice. (See People v. Capistrano (2014) 
    59 Cal.4th 830
    , 850 (Capistrano).) Rather, the issue is ― ‗ ―whether strong evidence
    of a lesser but inflammatory crime might be used to bolster a weak prosecution
    case‖ on another crime.‘ ‖ (Ibid.) In Capistrano, for instance, we held that
    joinder of a brutal rape incident with a separate robbery did not unduly inflame the
    jury against the defendant. (Ibid.) We so held, in part, because the evidence of the
    separate robbery was far from weak — the defendant had admitted his
    participation in the robbery. (Ibid.) We therefore found no abuse of discretion
    because there was little risk that details of the rape would have bolstered an
    otherwise weak robbery charge.
    Coleman illustrates the flip side of this point. There, the Court of Appeal
    explained that the evidence supporting the more serious murder charge was
    relatively weak. (See Coleman, supra, 116 Cal.App.3d at p. 138.) Indeed, ―the
    only evidence connecting defendant to the [murder] consists of the palm and
    thumb prints identified at the scene of the crime.‖ (Ibid.) ―If a juror has a
    reasonable and appropriate doubt about the identity of the murderer,‖ continued
    the court, ―the juror may find it difficult to maintain that doubt in the face of direct
    evidence concerning repulsive crimes against minors committed by [defendant].‖
    (Ibid.) As a result, the Court of Appeal found the trial court had abused its
    discretion in denying the defendant‘s motion to sever. (Id. at pp. 139-140.)
    29
    The situation here is similar to that in Capistrano. There is no reason to
    presume that the potentially inflammatory evidence of sex crimes from the
    Anes/Magpali incident was likely to prejudice Simon regarding the Sterling
    charges. Without question, the details of the Anes/Magpali incident are
    disturbing. But any effect this evidence would have had on the jury as a result of
    joinder was not unduly prejudicial given that the Sterling murder was no more
    serious an offense and was also supported by strong evidence. Unlike in Coleman,
    where joinder of inflammatory evidence was used to bolster a more serious — but
    weaker — case, the Anes/Magpali charges here independently gave rise to the
    death penalty by involving several special circumstance allegations. The
    Anes/Magpali murders, thus, cannot be characterized as the ―lesser‖ crimes.
    (Capistrano, supra, 59 Cal.4th at p. 850.) Moreover, unlike in Coleman, where
    the evidence supporting the joined murder charge was relatively weak, here — for
    reasons discussed below — the Sterling homicide was supported by strong
    evidence.
    There is little chance, likewise, that joinder of the Sterling matter
    prejudiced Simon with respect to the more inflammatory Anes/Magpali murders.
    True, we have recognized that gang evidence, even if relevant, can be ―highly
    inflammatory.‖ (McKinnon, supra, 52 Cal.4th at p. 655; see also Williams, supra,
    36 Cal.3d at p. 453 [explaining that ―evidence of gang membership . . . might
    indeed have a very prejudicial, if not inflammatory effect on the jury in a joint
    trial‖].) But Simon does not explain why introducing evidence of a gang rivalry
    was sufficiently inflammatory that denial of severance constituted an abuse of
    discretion. And our case law is to the contrary.
    In McKinnon, we held that the proffered gang evidence ―was not unduly
    inflammatory.‖ (McKinnon, supra, 52 Cal.4th at p. 631.) The defendant there
    was charged with two unrelated murders. In the first, the defendant walked up to a
    30
    stranger, placed a gun against that person‘s head, and shot him ―for no apparent
    reason.‖ (Id. at p. 620.) In the second, the defendant was engaged in an argument
    with a rival gang member before fatally shooting him. (Ibid.) In addition to
    evidence of gang name, membership, and rivalry, the prosecution submitted
    evidence that the defendant had shot the latter victim in retaliation for a separate
    gang-related murder. (Id. at pp. 624-625.)
    On appeal, the defendant argued that joinder of the charges was prejudicial
    because gang evidence from the second incident was unduly inflammatory.
    (McKinnon, supra, 52 Cal.4th at p. 631.) We rejected that argument for three
    reasons: (1) the prosecution did not present any other evidence of gang violence
    aside from evidence that the murder was related to a prior gang-related killing, (2)
    any inflammatory effect of the gang evidence ―paled in comparison‖ to the
    prejudicial impact of the ―absolute senselessness‖ of the first incident, and (3) any
    inflammatory effect was not prejudicial because both cases were supported by
    strong evidence. (Ibid.)
    So too here. In this case, as in McKinnon, the gang evidence from one
    incident (i.e., the Sterling murder) was not likely to alter the outcome of the other
    (i.e., the Anes/Magpali murders). In fact, there was even less gang evidence
    introduced here than in McKinnon. In that case, in addition to gang name,
    membership, and rivalry, evidence was introduced of a separate gang-related
    killing. (McKinnon, supra, 52 Cal.4th at p. 631.) The only gang evidence
    admitted here, in contrast, was limited testimony that Sterling‘s gang affiliation
    served as the impetus for Simon‘s rage. Furthermore, any inflammatory effect of
    the limited gang evidence here ―paled in comparison‖ to the prejudicial effect of
    the murder, kidnapping, and rape charges in the Anes/Magpali incident. (Ibid.)
    This point is even clearer here than was the case in McKinnon, where the
    31
    prejudicial impact of the other crime was its ―senselessness‖ (ibid.); here, the
    Anes/Magpali charges were both senseless and gruesome.
    Unlike in Williams, moreover, where gang affiliation was used to implicate
    the defendant as the perpetrator, the gang evidence here was neither relied on nor
    was it necessary to link Simon to the strongly supported Anes/Magpali charges.
    (Cf. Williams, supra, 36 Cal.3d at p. 453.) Not only was there DNA evidence
    linking Simon to the Anes/Magpali murders, but Simon was also found in
    possession of the gun used to kill both victims. What made the gang evidence in
    Williams prejudicial — to wit, that a jury not otherwise convinced beyond a
    reasonable doubt of the defendant‘s involvement might use gang evidence to tip
    the scales and convict — is therefore not a concern in the present case. (See also
    Capistrano, supra, 59 Cal.4th at p. 853 [joinder of attempted murder charge did
    not deprive defendant of a fair trial where the only evidence of defendant‘s gang
    membership was the victim‘s testimony that ―he believed defendant was a gang
    member‖]; People v. Sandoval, 
    supra,
     4 Cal.4th at p. 173 [defendant failed to
    show requisite prejudice from joinder of other murder charges because any
    ―inflammatory effect of defendant‘s gang membership as to the [other] case was
    neutralized by the fact that the victims were also gang members‖].)
    Only when a defendant has made a clear showing of potential prejudice
    may we find an abuse of discretion in this context. (See Mendoza, 
    supra,
     24
    Cal.4th at p. 160.) There was none here. Simon has not shown the potentially
    inflammatory evidence from the Anes/Magpali incident would have altered the
    outcome of the Sterling charges, or vice versa.
    (c) Weak Case Joined to Strong Case
    Simon fails to establish a clear showing of potential prejudice under this
    factor because neither the Anes/Magpali incident nor the Sterling incident was a
    32
    weak case that needed joinder to bolster the likelihood of conviction. (See People
    v. Balderas (1985) 
    41 Cal.3d 144
    , 173-174.)
    The core prejudice concern arising in connection with this issue is that
    jurors may aggregate evidence and convict on weak charges that might not merit
    conviction in separate trials. (Williams, supra, 36 Cal.3d at p. 453.) This concern
    is especially pronounced when evidence of a lesser but inflammatory incident
    might be used to bolster a weak prosecution case as to another incident.
    (Capistrano, supra, 59 Cal.4th at p. 850.) But even where evidence from one
    incident could be considered ―inflammatory‖ as the term is understood in our case
    law (see id. at pp. 850-851), we will find no abuse of discretion if the evidence of
    guilt for each of the joined incidents is sufficiently compelling (see, e.g.,
    McKinnon, 
    supra,
     52 Cal.4th at p. 631 [―This was not a matter in which a weak
    case was joined with a strong case, or with another weak case, thereby ‗causing a
    spillover effect that might have unfairly altered the outcome of the trial.‘
    [Citation.] Strong evidence supported both cases‖]).
    Such is the case here. Both the Anes/Magpali and Sterling charges were
    supported by strong evidence that would likely have merited conviction in
    separate trials. As to the Anes/Magpali incident, Simon conceded below that
    strong evidence supported these charges. The most damaging piece of evidence
    was that Simon‘s DNA profile matched the DNA profile of semen evidence
    collected from Magpali‘s body and clothing. Such evidence, we have held many
    times, indicates a strong case. (See, e.g., People v. Scott (2015) 
    61 Cal.4th 363
    ,
    396; People v. Hartsch (2010) 
    49 Cal.4th 472
    , 494; People v. Geier (2007) 
    41 Cal.4th 555
    , 576.) In addition, Simon was found in possession of the gun used to
    kill Anes and Magpali during a traffic stop less than seven weeks after the
    murders. Simon also exhibited a guilty mind following that stop in trying to
    coerce Meeks, Simon‘s front seat passenger, to claim ownership of the firearm.
    33
    As to the Sterling incident, Simon concedes there was ―strong proof‖ he
    shot and killed Sterling. Nonetheless, Simon argued below that the Sterling
    charges were ―weak‖ because evidence purportedly suggested the killing was
    justified as self-defense or could be mitigated to manslaughter by imperfect self-
    defense. Although the availability of defense theories may be relevant under this
    factor, there was very little to support the defenses Simon offered in this case.
    There was no meaningful evidence either that Sterling was armed or that he was
    the aggressor. Quite the opposite. There was substantial evidence in the record
    that Simon was the aggressor. In light of the admittedly strong proof that Simon
    shot and killed Sterling, combined with testimony that Simon was the aggressor,
    we find these charges supported by strong evidence. (See People v. Johnson
    (2015) 
    61 Cal.4th 734
    , 752 [―Although defendant presented an alibi defense to
    [one of the murders], a mere imbalance in the evidence between the joined crimes
    does not signal a risk that one charge will be prejudicially bolstered‖].)
    Simon‘s possession of the gun used to kill Anes and Magpali, DNA
    evidence linking Simon to Magpali‘s rape, and uncontroverted evidence that
    Simon — after having been the aggressor — shot Sterling indicate that both
    incidents were supported by strong evidence. Consequently, we find no clear
    showing of potential prejudice under this factor.
    (d) Capital Offense
    Although joinder resulted in the Sterling murder being charged as a capital
    offense, Simon has not clearly shown potential prejudice under this factor because
    joining the charges neither converted the entire matter into a capital case nor
    bolstered the possibility of Simon receiving a death sentence.
    Denials of severance involving capital charges generally require a ―higher
    degree of scrutiny and care.‖ (Williams, supra, 36 Cal.3d at p. 454.) Even greater
    34
    scrutiny is required, we have said, when the joinder of separate murder charges
    gives rise to the special circumstance allegation of multiple murder. (Ibid.) But
    nothing in our prior cases suggests that severance is required whenever capital
    charges are involved. (People v. Balderas, supra, 41 Cal.3d at p. 171.) Further,
    where one of two joined murder incidents would independently give rise to a
    capital charge, there is less risk of prejudice. (See People v. Johnson, supra, 61
    Cal.4th at p. 752 [explaining that ―joinder of the two killings did not convert the
    matter into a capital offense because [one of the killings] included two kidnapping
    and robbery special-circumstance allegations and thus made defendant eligible for
    the death penalty‖]; People v. Ruiz (1988) 
    44 Cal.3d 589
    , 607 [―unlike the
    situation in Williams, joinder of the Tanya murder charge did not convert the case
    into a capital one, for the properly joined Pauline/Tony charges alone satisfied the
    multiple-murder special-circumstance statute‖].)
    Here, joining the charges did not convert the matter into a capital case, and
    the separate offenses were supported by strong evidence. Without joinder, Simon
    would still have faced the death penalty based on the special circumstance
    allegations that the murder of Anes was committed during the commission of a
    robbery and the murder of Magpali was committed during the commission of a
    robbery, kidnapping, and rape. (Former § 190.2, subd. (a)(17)(i)-(iii), now
    § 190.2, subd. (a)(17)(A)-(C).) Moreover, the multiple-murder special-
    circumstance allegation was available to the prosecution, even if the Sterling
    murder had not been joined, because the Anes/Magpali incident involved two
    murders. (See People v. Ruiz, supra, 44 Cal.3d at p. 607.) As a result, joining the
    charges did not convert the matter into a capital case.
    Furthermore, there was strong evidence supporting each incident. So
    neither case posed an undue risk of unjustified conviction. (See People v. Myles
    (2012) 
    53 Cal.4th 1181
    , 1202 [―In the present case, the evidence supporting each
    35
    of the murder cases was not weak and neither case posed the risk of an
    unjustifiable conviction‖]; People v. Thomas (2012) 
    53 Cal.4th 771
    , 800 [finding
    ―no significant risk of an unjustified conviction on any of the murder charges
    because . . . evidence in both cases was strong‖].) Because joinder did not bolster
    the possibility of conviction, joinder also did not bolster the possibility of the
    death penalty being imposed as punishment. We find no clear showing of
    potential prejudice under this factor.
    ii. Gross Unfairness
    Even if we find that the trial court did not abuse its discretion in denying
    severance pretrial, we must also determine ―whether events after the court‘s ruling
    demonstrate that joinder actually resulted in ‗gross unfairness‘ amounting to a
    denial of defendant‘s constitutional right to fair trial or due process of law.‖
    (People v. Merriman, supra, 60 Cal.4th at p. 46.) We find no violation of due
    process.
    In determining whether joinder resulted in gross unfairness, we have
    observed that a judgment will be reversed on this ground only if it is reasonably
    probable that the jury was influenced by the joinder in its verdict of guilt. (People
    v. Merriman, supra, 60 Cal.4th at p. 49.) But, as noted above, both the
    Anes/Magpali charges and the Sterling charges were supported by strong evidence
    warranting conviction had the incidents been tried separately. What is more, the
    fact that the jury found Simon guilty of first degree murder in the killings of Anes
    and Magpali, but only second degree murder of Sterling, ―strongly suggests that
    the jury was capable of weighing the evidence and differentiating among [the]
    various charges.‖ (People v. Lucas (2014) 
    60 Cal.4th 153
    , 217, disapproved on
    another ground in People v. Romero and Self (2015) 
    62 Cal.4th 1
    , 53, fn. 19; see
    also People v. Jones (2013) 
    57 Cal.4th 899
    , 927 [―Where the jury returns a guilty
    36
    verdict of a lesser crime, or, as here, fails to convict at all on some charges, we are
    confident the jury was capable of, and did, differentiate among defendant‘s
    crimes‖]; People v. Ruiz, supra, 44 Cal.3d at p. 607 [―the fact that the jury found
    defendant guilty of only second degree murder of Tanya strongly suggests that the
    jury was capable of differentiating between defendant‘s various murders‖].)
    Simon argues nonetheless that joinder resulted in gross unfairness because
    the trial court failed to adequately caution jurors against considering evidence
    from the Anes/Magpali incident when rendering a verdict on the Sterling counts,
    and vice versa. But the court instructed the jury, pursuant to CALJIC No. 17.02,
    as follows: ―Each count charges a distinct crime. You must decide each Count
    separately. The defendant may be found guilty or not guilty of any or all of the
    crimes charged. Your finding as to each Count must be stated in a separate
    verdict.‖ Defense counsel also reminded the jury of its duty to consider the facts
    separately in his closing argument. Absent some showing to the contrary — a
    showing Simon has not provided — we presume the jury followed these
    instructions. (See People v. Merriman, supra, 60 Cal.4th at pp. 48-49 [―The
    record shows moreover that the jury was instructed on the elements of each of the
    charged crimes, told that ‗each count charges a distinct crime,‘ and directed to
    ‗decide each count separately.‘ (CALJIC No. 17.02.) Absent some showing to
    the contrary, we presume the jury followed the court‘s instructions. [Citation.]
    No such showing was made here‖].)
    Simon‘s reliance on Bean v. Calderon (9th Cir. 1998) 
    163 F.3d 1073
    (Bean) is unavailing. In that case, the Ninth Circuit held that, despite the state trial
    court‘s having instructed the jury pursuant to CALJIC No. 17.02, the court‘s
    refusal to sever two sets of charges deprived the defendant of a fair trial. (Id. at
    p. 1083.) Bean is distinguishable on several grounds. First, the prosecutor during
    closing argument there ―repeatedly urged the jury to consider evidence of Bean‘s
    37
    ‗modus operandi‘ to determine whether he was guilty of both [sets of] crimes.‖
    (Ibid.) Although the prosecutor here, in a couple of instances during closing
    argument, appeared to cross-reference the two incidents, these isolated remarks
    over the course of 80 pages of transcript did not approach the repeated conflation
    of events found in Bean. Second, unlike in Bean, there is no ―substantial
    disparity‖ (id. at p. 1085) between the strength of the two cases here such that the
    evidence from one risked strengthening an ―otherwise weak case‖ (id. at p. 1083).
    As explained above, the evidence supporting both sets of charges was quite strong
    here. Simon was arrested with the Anes/Magpali murder weapon, and Simon‘s
    DNA profile matched that of semen evidence collected from Magpali.
    Uncontroverted evidence also showed that Simon — after having been the
    aggressor — shot Sterling in the chest. Third, unlike in Bean, there is ―affirmative
    evidence of the jury‘s ability to assess the [two incidents] separately.‖ (Id. at
    p. 1086.) The jury here found Simon guilty of first degree murder in the killings
    of Anes and Magpali, but only second degree murder of Sterling. We therefore
    have no compelling reason to doubt that the jury succeeded in sufficiently
    compartmentalizing the evidence. (Id. at p. 1085.)
    What we conclude in light of these factors is that Simon has not shown
    joinder to have resulted in gross unfairness such that he was deprived of a fair
    trial.
    3. Failure to Instruct on Imperfect Self-Defense
    Simon argues that the trial court erred in failing to instruct the jury on
    imperfect self-defense with respect to the Sterling homicide. We see no error.
    a. Background
    In arguing before the trial court for jury instructions on self-defense,
    defense counsel cited testimony that Sterling had been convicted of a prior assault,
    38
    Haynes‘s statements that she observed an argument outside between Sterling and
    Simon, testimony by Haynes and Gentry that they heard three gunshots fired
    (implying the existence of another gun), testimony by Gentry that Sterling was
    bigger than Simon, and testimony that the fatal shot was fired at close range.
    From this evidence, defense counsel asserted, ―it appears from the record at least a
    reasonable inference could be drawn that Mr. Simon and Mr. Sterling are arguing
    with each other.‖
    The prosecutor conceded there was evidence that Sterling and Simon had
    been arguing, but that any potential third shot fired most likely came from the
    same gun. The prosecutor continued that the defense failed to make a case for
    imperfect self-defense ―because there‘s no evidence whatsoever of any fear or
    honest belief on [Simon‘s] part here,‖ and ―[b]ecause we have no idea whatsoever
    of any aggressive behavior by Mr. Sterling toward Mr. Simon.‖
    The trial court denied Simon‘s request for a jury instruction on imperfect
    self-defense, stating ―No, I don‘t see it, to be honest with you. I don‘t think
    there‘s a factual basis for this . . . .‖ The instructions jurors did receive gave them
    the option to find Simon guilty of the lesser included offense of voluntary
    manslaughter under a heat of passion or sudden quarrel theory, or to acquit Simon
    based on a theory of complete self-defense. Simon now challenges the trial
    court‘s refusal to instruct the jury on imperfect self-defense, arguing that a jury
    could have concluded that he had an actual but unreasonable belief that he needed
    to defend himself against imminent harm from Sterling.
    b. Legal Standard
    An instance of imperfect self-defense occurs when a defendant acts in the
    actual but unreasonable belief that he or she is in imminent danger of great bodily
    injury or death. (People v. Duff (2014) 
    58 Cal.4th 527
    , 561.) Imperfect self-
    39
    defense differs from complete self-defense, which requires not only an honest but
    also a reasonable belief of the need to defend oneself. (People v. Elmore (2014)
    
    59 Cal.4th 121
    , 133-134.) It is well established that imperfect self-defense is not
    an affirmative defense. (See People v. Barton (1995) 
    12 Cal.4th 186
    , 199-201
    (Barton).) It is instead a shorthand way of describing one form of voluntary
    manslaughter. (Id. at p. 200.) Because imperfect self-defense reduces an
    intentional, unlawful killing from murder to voluntary manslaughter by negating
    the element of malice, this form of voluntary manslaughter is considered a lesser
    and necessarily included offense of murder. (People v. Breverman (1998) 
    19 Cal.4th 142
    , 154.)
    A trial court has a sua sponte duty to instruct the jury on a lesser included
    uncharged offense if there is substantial evidence that would absolve the defendant
    from guilt of the greater, but not the lesser, offense. (People v. Waidla (2000) 
    22 Cal.4th 690
    , 733 (Waidla).) Substantial evidence is evidence from which a jury
    could conclude beyond a reasonable doubt that the lesser offense was committed.
    (People v. Manriquez (2005) 
    37 Cal.4th 547
    , 587-588 (Manriquez); see also
    Barton, 
    supra,
     12 Cal.4th at p. 201, fn. 8 [―Substantial evidence is evidence
    sufficient to ‗deserve consideration by the jury,‘ that is, evidence that a reasonable
    jury could find persuasive‘ ‖].) Speculative, minimal, or insubstantial evidence is
    insufficient to require an instruction on a lesser included offense. (Mendoza,
    
    supra,
     24 Cal.4th at p. 174; see also Barton, at p. 201 [―the need to [instruct sua
    sponte on imperfect self-defense] arises only when there is substantial evidence
    that the defendant killed in unreasonable self-defense, not when the evidence is
    ‗minimal and insubstantial‘ ‖ (fn. omitted)].)
    We review de novo a trial court‘s decision not to give an imperfect self-
    defense instruction. (See Manriquez, 
    supra,
     37 Cal.4th at p. 581; see also Waidla,
    
    supra,
     22 Cal.4th at p. 733 [―An appellate court applies the independent or de
    40
    novo standard of review to the failure by a trial court to instruct on an uncharged
    offense that was assertedly lesser than, and included, in a charged offense‖].)
    c. Analysis
    According to Simon, ―a theory of unreasonable self-defense was supported
    by the evidence since jurors may have concluded that [he] actually believed in the
    need for self-defense, but that his belief was not objectively reasonable.‖ In
    support of this claim, Simon emphasizes how, after his initial showing of
    aggressive behavior, he apologized, shook Sterling‘s hand, and hugged him before
    leaving the apartment.
    We disagree. The facts, though hardly pellucid, suggest that Simon — not
    Sterling — was the aggressor in their confrontation. It was Simon who began
    cursing at Sterling after the latter identified himself as a member of IE, an
    apparent rival of Simon‘s gang. Despite Sterling lifting up his shirt to prove that
    he was unarmed, Simon asked for someone to retrieve the gun Simon had brought
    to the apartment. Simon asserts he was a changed man once he returned from the
    bathroom, claiming that he had ―calmed down‖ at that point and that he had
    apologized to Sterling as he shook his hand. Yet moments later, Simon walked
    over to Williams and elbowed him in the face. When Gentry sought to intervene,
    Simon told her to ―shut up,‖ threatening to shoot her too. Once outside, Simon
    and Sterling began to argue. And in an interview with police, Jamal Brown said
    that Simon ―totally shot [Sterling] cold blooded.‖ Jamal remarked that Simon had
    ―shot [Sterling,] what for I don‘t know.‖ Jamal also insisted that he had heard
    only two gunshots.
    Simon, meanwhile, does not point to any evidence indicating that Sterling
    was the aggressor. Nor does Simon present evidence that he ever perceived that
    Sterling –– who was unarmed –– posed a risk of imminent peril. Given the
    41
    paucity of support for Simon‘s position, our decision in Manriquez is also
    instructive. (Manriquez, supra, 37 Cal.4th at pp. 580-583.) There, we rejected the
    defendant‘s claim that the trial court improperly refused his request for a jury
    instruction on imperfect self-defense, noting that the record was ―devoid of
    evidence‖ supporting the defendant‘s subjective fear. (Id. at p. 581.) The
    evidence there included how the defendant had allegedly told officers he ― ‗had
    heard some threats‘ ‖ that the victim wanted to kill him. (Id. at p. 582.) A witness
    to the murder testified that the defendant appeared angry when he left the room to
    meet the victim, that the victim was unarmed, and that the victim asked the
    defendant, ― ‗What is your problem with me?‘ ‖ (Id. at pp. 561-562.) The
    defendant did not testify at trial. (Id. at pp. 567-568.)
    The record here is equally devoid of evidence tending to show Simon‘s
    subjective fear of Sterling. Simon, like the defendant in Manriquez, initiated any
    aggressive interactions — here, by cursing at Sterling for being a member of a
    rival gang. Similarly, the record indicates that Sterling was unarmed. Simon also
    did not testify, and there is no evidence he ever told anyone that he had acted out
    of fear.
    To the extent Simon argues that the trial court‘s decision to give an
    instruction on complete self-defense required it to also instruct on imperfect self-
    defense, we find no error. Because we conclude there was not substantial
    evidence supporting Simon‘s actual belief that he was in imminent danger of great
    bodily injury or death, the trial court would not have erred had it likewise refused
    to instruct on complete self-defense. (See People v. Rodriguez (1997) 
    53 Cal.App.4th 1250
    , 1270 [―Further, just because the court permitted instructions on
    perfect self-defense does not mean that substantial evidence supported the giving
    of an imperfect self-defense instruction. To the contrary, it would not have been
    error for the trial court to have denied perfect self-defense instructions with regard
    42
    to Contreras because no substantial evidence supported such a defense‖]; see also
    People v. De Leon (1992) 
    10 Cal.App.4th 815
    , 824 [―It is hard to fault appellant‘s
    logic. If there was substantial evidence of his ‗honest belief‘ for self-defense
    purposes, there was substantial evidence of his ‗honest belief‘ for imperfect self-
    defense purposes. [¶] But we are satisfied, and so hold, there was not substantial
    evidence of ‗honest belief‘ for either self-defense or imperfect self-defense‖].)
    We conclude the trial court did not err in refusing Simon‘s request to
    instruct on imperfect self-defense.
    C. Penalty Phase Issues
    1. Victim Impact Evidence
    Simon argues that the trial court committed reversible error in admitting
    victim impact evidence during the penalty phase of his trial. We are not
    convinced.
    a. Background
    Prior to the penalty phase, Simon moved to exclude victim impact evidence
    on multiple grounds. First, Simon called for exclusion of testimony regarding the
    appropriate punishment for or characteristics of Simon. The trial court agreed.
    Second, Simon requested to limit victim impact testimony to a single surviving
    family member. The trial court denied the motion, noting that ―California has
    never placed‖ such a limitation. Third, Simon sought to exclude emotional,
    tearful, or angry testimony, explaining that some testimony had been very
    emotional in the first penalty trial. The trial court agreed that testimony may not
    be so emotional that it becomes unduly prejudicial. The court reasoned, however,
    that it could not ex ante exclude or even distinguish what qualifies as ―overly
    emotional or inflammatory.‖ The court therefore ruled that this issue was
    something to monitor as the proceedings developed.
    43
    Fourth, Simon moved to exclude any testimony or evidence regarding
    awards or academic achievements of the victims — a request the trial court
    promptly denied. Fifth, Simon asked to exclude artwork by Magpali. The trial
    court denied the motion but stipulated that such evidence not be ―overly time
    consuming or overly prejudicial.‖ Similarly, Simon moved to exclude ―testimony
    regarding future plans‖ of the victims. The trial court ruled such evidence
    admissible, reiterating again that such testimony may not be overly time
    consuming or specific.
    Sixth, Simon sought to exclude photographs and testimony going back to
    the victims‘ births, suggesting that any such evidence be limited to ―a period of
    time closer to the time of death.‖ The trial court denied Simon‘s objections to
    both the baby photographs and the testimony. And seventh, Simon requested that
    all victim impact evidence be excluded because such testimony is so broad that it
    violates the Eighth Amendment to the United States Constitution and article 1,
    section 17 of the California Constitution. The trial court denied the motion while
    repeating that there would be limitations. The court recognized that the critical
    question is whether victim impact evidence becomes ―overly time consuming,
    overly repetitious, things of that nature,‖ which could not be determined at a
    pretrial hearing.
    b. Evidence Presented
    i. Sherry Magpali
    Two victim impact witnesses testified regarding Sherry Magpali: her sister
    Jasmine and brother Jeffrey.
    At the time of her death, Sherry was a 19-year-old student at a local
    community college, having graduated magna cum laude from high school the year
    before. Jasmine and Jeffrey described their sister as a creative, fun person with a
    44
    lot of friends. Sherry enjoyed singing, playing dress up, and taking pictures with
    her siblings. She also hoped to become an artist and was interested in graphics,
    Japanese animation, and poetry. Some of Sherry‘s artwork was entered into
    evidence, along with photographs of Sherry as a baby, young child, and young
    adult.
    The night of the incident, Sherry asked Jasmine and Jeffrey to go with her
    to the party, but both declined. The next day, her siblings were at a church retreat
    when they were pulled aside and told they had to be taken home. Although they
    were not told what had happened, Jasmine said she already knew something was
    wrong. Jasmine described getting home, hearing people screaming, seeing her
    mother lying on the floor after fainting, and no one telling her what was going on.
    Jasmine did not learn about how her sister was murdered until she read the
    newspaper. Jasmine described being angry when she heard about the way her
    sister was killed. And as a result of her sister‘s death, Jasmine said she became
    introverted and was no longer a trusting person. She said her brother Jeffrey
    became the same way.
    Jeffrey testified that at first he did not believe Sherry had been murdered
    because she was such a strong person. He said it hurt knowing how his sister died
    and that it would have been different if Sherry had died some other way, like in a
    car accident or from a medical condition. He said it was also difficult to attend the
    funeral because that was when he realized his sister was really gone.
    Jasmine described the impact of Sherry‘s death on their mother. For years
    after the incident, Jasmine woke up to her mother crying in the middle of the
    night. She also explained that the family did not talk to each other much anymore;
    holidays, she said, felt empty.
    45
    ii. Vincent Anes
    Regarding Vincent Anes, three victim impact witnesses testified: his
    mother Priscilla Severson, his stepfather Timothy Severson, and his brother Dino
    Anes. Jurors were shown approximately 11 photographs of Vincent, ranging from
    age seven to death.
    Priscilla described Vincent as a good, sweet, and thoughtful boy who was
    never in trouble. Vincent was a playful, but obedient, son who always did his
    homework and helped his younger brother with math. Vincent had a close
    connection with his stepfather, who taught Vincent how to work on cars. At the
    time of his death, Vincent was a senior in high school and a good student. Vincent
    planned on joining the military, then going to college to become a dentist.
    The night of the incident, Priscilla was awakened by Vincent‘s friends,
    asking if he was home. She did not understand what Vincent‘s friends were
    saying, though, and thought Vincent might have just been in a car accident. Dino
    was also awakened and recalled people panicking and screaming. Priscilla called
    her parents, who lived nearby, and they all drove to the park. On the way, Dino
    prayed that his brother was still alive.
    Upon arrival, Priscilla and Dino saw Vincent‘s car but were still unaware
    that Vincent was dead. An ambulance arrived too, but no one seemed to be
    helping the person in the car — this was the first indication to Dino that his
    brother was dead. It was only after Priscilla‘s father told her the person in the
    vehicle was Vincent that she knew her son had died.
    Timothy testified that he blamed himself for Vincent‘s death. Timothy,
    who served in the military and was stationed in Nevada at the time, described how
    it was difficult to cope with knowing he had left his family in a place where
    Vincent was murdered. The night of the incident, Timothy was awakened by a
    coworker saying that he had a phone call. Because Priscilla was so distraught,
    46
    though, she was unable to speak, so her brother had to explain what had occurred.
    Timothy processed paperwork through the Red Cross and got permission from his
    superiors to leave, but he was only able to stay with his family in California for a
    few weeks. It was difficult to leave so quickly, he told the jury.
    Priscilla explained that home life was happy before Vincent‘s death. After
    the incident, though, she became very fearful and strict toward Dino. Afraid that
    something similar to what happened to Vincent might happen to her other son,
    Priscilla would turn the ringer of the house phone off on the weekends so that
    Dino‘s friends could not reach him. Although she stopped doing this at some
    point because it was not fair to Dino, she still lived in fear whenever Dino left the
    house. Priscilla also explained that she was bothered by the way Vincent died and
    that she still had nightmares.
    Vincent‘s death had a significant impact on Dino, who said he became a
    loner. Dino testified that it was difficult to accept his brother‘s death because of
    how he was killed; had Vincent died because of a car accident or a medical
    condition, it would have been different. Dino could not accept how his brother
    was ―brutally murdered‖ and ―humiliated.‖ Dino went on to explain that when he
    could not sleep at night, he thought about his brother. Dino said he did not pray
    anymore because God did not answer his prayers the night Vincent was murdered.
    The family moved away from the area four months after the incident, but
    for two years Priscilla traveled to visit the cemetery three or four times a week.
    Priscilla described how she saved all of Vincent‘s belongings, including the last
    bottle of soda she had shared with him. She explained that the family no longer
    celebrated holidays, finding it meaningless to even put up a Christmas tree.
    47
    iii. Michael Sterling
    Michael Sterling‘s sister-in-law, Dyanne Sterling, testified about the effect
    of Michael‘s death on her husband (i.e., Michael‘s brother) and son. Michael was
    very close to his three brothers, who were all affected by Michael‘s death.
    Dyanne‘s son, who was six when Michael died, was also affected. He cried
    frequently and missed his uncle.
    c. Legal Standard
    In a capital case, the Eighth and Fourteenth Amendments to the United
    States Constitution permit introduction of evidence about the victim or the impact
    of the defendant‘s acts on the victim‘s friends and family. (Payne v. Tennessee
    (1991) 
    501 U.S. 808
    , 825-827.) Such victim impact evidence is only barred by the
    federal Constitution if it is so unduly prejudicial that it renders the trial
    fundamentally unfair. (People v. Kopatz (2015) 
    61 Cal.4th 62
    , 90 (Kopatz).)
    Fundamental unfairness results when testimony ―invite[s] the jury to make its
    penalty determination on a purely irrational basis.‖ (People v. Taylor (2010) 
    48 Cal.4th 574
    , 646.) California law provides further that victim impact evidence is
    admissible under section 190.3, factor (a) as a ―circumstance of the crime.‖
    (People v. Edwards (1991) 
    54 Cal.3d 787
    , 835-836 (Edwards).) Pursuant to
    factor (a), trial courts may allow emotional though relevant evidence, but not
    irrelevant information or inflammatory rhetoric that elicits purely emotional or
    irrational responses from the jury. (Id. at p. 836; see also People v. Pollock (2004)
    
    32 Cal.4th 1153
    , 1180.)
    We review the trial court‘s admission of victim impact evidence for abuse
    of discretion. (People v. Trinh (2014) 
    59 Cal.4th 216
    , 245.)
    d. Analysis
    On appeal, Simon raises three arguments. First, the amount and nature of
    the victim impact evidence proffered below violated the due process clause of the
    48
    Fourteenth Amendment to the United States Constitution. Second, the scope of
    victim impact evidence admissible under section 190.3, factor (a) should be
    limited to characteristics of the victims known or reasonably apparent to Simon at
    the time of the offense, and a more expansive interpretation renders the statute
    unconstitutionally vague under the Eighth Amendment to the United States
    Constitution and article I, section 17 of the California Constitution. Third, the
    proposed victim impact evidence should have been excluded under Evidence Code
    section 352 because the risk of undue prejudice substantially outweighed the
    evidence‘s probative value.
    i. Due Process
    Simon argues that the victim impact evidence presented below violated the
    due process clause of the Fourteenth Amendment to the United States Constitution
    because it was so unduly prejudicial that it rendered the penalty phase
    fundamentally unfair. Simon contends the amount, and emotional nature, of the
    victim impact evidence was so inflammatory that the jury was led to make a
    ―passionate, irrational, and purely subjective‖ decision based on the sorrow of the
    victims‘ families.
    But we need not address whether the amount or emotional nature of the
    victim impact evidence was unconstitutionally prejudicial. Because Simon failed
    to properly object to the evidence, he forfeited the issue on appeal. (See People v.
    Wilson (2005) 
    36 Cal.4th 309
    , 357 [concluding that ―defendant forfeited his claim
    because he failed to object to the testimony as exceeding the scope of section
    190.3, factor (a)‖].) Although Simon raised many objections to the scope of
    permissible victim impact evidence prior to the penalty phase, the trial court
    reached few express rulings: (1) testimony need not be limited to one witness per
    victim, (2) evidence of awards, artwork, achievements, and future plans were not
    49
    per se inadmissible, and (3) testimony and evidence need not be limited to the time
    surrounding the victims‘ deaths.
    The trial court also warned that the victim impact evidence should not be
    overly time consuming or overly emotional, but the court deferred making any
    specific rulings on this score pretrial. It was therefore incumbent upon Simon to
    monitor the victim impact evidence on an ongoing basis during the penalty phase
    and raise any specific objections at that time. (See People v. Romero and Self,
    supra, 62 Cal.4th at pp. 45-46 [finding victim impact evidence claim ―forfeited‖
    because the ―motion in limine sought to broadly exclude all victim impact
    evidence on constitutional grounds, and did not specifically object to the
    admission of any particular witness‘s testimony anticipated in this case‖; instead,
    ―it was incumbent on defendants to object if they believed the testimony actually
    presented was ‗excessive, improper, inflammatory, and highly prejudicial‘ ‖].)
    Even if Simon‘s claim were not forfeited, his argument fails on the merits
    because the victim impact evidence was not unduly prejudicial. The family
    members‘ testimony here properly described the nature of their relationships with
    the victims, how they learned about the crimes, and how the crimes impacted their
    lives. (See Kopatz, supra, 61 Cal.4th at p. 91 [finding no error where ―the family
    members‘ testimony properly explained the nature of their relationship with the
    victims, the immediate effects of the murders, and the residual and continuing
    impact of the murder on their lives‖]; People v. Chism (2014) 
    58 Cal.4th 1266
    ,
    1326-1327 (Chism) [finding no error where the family members‘ testimony ―was
    limited to explain the nature of their relationship with the victim, the immediate
    effects of the murder, and the residual and continuing impact of the murder on
    their lives‖].) Furthermore, neither the number of witnesses — six — nor the
    amount of testimony — 59 pages‘ worth — was excessive. (See, e.g., People v.
    Romero and Self, supra, 62 Cal.4th at p. 46 [no error where victim impact
    50
    testimony consisted of six witnesses spanning 96 pages of the reporter‘s
    transcript]; see also People v. Pearson (2013) 
    56 Cal.4th 393
    , 464-467 [victim
    impact testimony of 13 witnesses]; People v. Nelson (2011) 
    51 Cal.4th 198
    , 219-
    221 [victim impact testimony of one victim‘s six family members].)
    Moreover, the content of the victim impact evidence was not so emotional
    that it became unduly prejudicial. Simon is likely correct that the testimony
    painted a picture of ―the complete devastation of two families,‖ but that is to be
    expected when loved ones have been brutally murdered. (See Kopatz, supra, 61
    Cal.4th at pp. 90-91 [explaining that the devastating effect of a capital crime on
    loved ones and the community is generally relevant and admissible]; Chism,
    supra, 58 Cal.4th at p. 1328 [―Evidence presented at the penalty phase need not be
    devoid of emotional content‖].) The question is not simply whether victim impact
    evidence was emotional or demonstrated the devastating effect of the crime;
    rather, it is whether the testimony invited an irrational response from the jury.
    (See People v. Tully (2012) 
    54 Cal.4th 952
    , 1030.) Simon, however, provides no
    persuasive basis for us to conclude that the testimony presented in this case
    triggered such a response. And our review of the record indicates the testimony
    was not so emotional that the trial court‘s failure to exclude it amounted to an
    abuse of discretion or rendered Simon‘s trial fundamentally unfair. (See People v.
    Trinh, supra, 59 Cal.4th at pp. 245-246.)
    ii. Vague
    Simon argues that in Edwards, 
    supra,
     
    54 Cal.3d 787
    , we incorrectly held
    that victim impact evidence admitted under section 190.3, factor (a) may
    encompass facts unknown to the defendant at the time of the offense. As support,
    Simon relies on Justice Kennard‘s concurring and dissenting opinion in People v.
    Fierro (1991) 
    1 Cal.4th 173
    , which advanced such an interpretation. (Id. at
    51
    pp. 262-263 (conc. & dis. opn. of Kennard, J.).) Simon also argues that
    interpreting section 190.3, factor (a) to include facts unknown or not reasonably
    apparent to him at the time of the offense renders the statute unconstitutionally
    vague.
    As Simon acknowledges, however, we have rejected these arguments ––
    and we have done so repeatedly –– since Edwards was decided. (See, e.g.,
    People v. Montes (2014) 
    58 Cal.4th 809
    , 877; People v. Zamudio (2008) 
    43 Cal.4th 327
    , 364-365; People v. Lewis and Oliver, supra, 39 Cal.4th at p. 1057;
    People v. Boyette (2002) 
    29 Cal.4th 381
    , 445, fn. 12.) Simon offers no different or
    persuasive reason for us to revisit our prior rulings.
    iii. Evidence Code Section 352
    Evidence Code section 352 provides: ―The court in its discretion may
    exclude evidence if its probative value is substantially outweighed by the
    probability that its admission will (a) necessitate undue consumption of time or (b)
    create substantial danger of undue prejudice, of confusing the issues, or of
    misleading the jury.‖ Simon contends that the victim impact evidence should have
    been excluded under this provision as substantially more prejudicial than
    probative. What he argues is that the victim impact evidence was ―bound to
    intensify natural feelings of sympathy for the victims and their families and may
    have encouraged a desire for retribution against [Simon by] inviting an emotional
    and purely subjective response‖ because it was not limited to a single witness or to
    the time surrounding the victims‘ deaths, and it was ―emotionally charged and
    detailed.‖
    We find no abuse of discretion here. (See People v. Brady (2010) 
    50 Cal.4th 547
    , 583 [reviewing cumulative effect of victim impact testimony under
    Evid. Code, § 352 for abuse of discretion].) The victim impact evidence was not
    52
    unduly prejudicial because the testimony did not invite the jury to form an
    ― ‗irrational, purely subjective response.‘ ‖ (Edwards, 
    supra,
     54 Cal.3d at p. 836.)
    The testimony here properly described how the murders impacted the witnesses‘
    lives and did not paint a picture of the crimes as any more disturbing than the
    evidence already showed. (See Kopatz, supra, 61 Cal.4th at p. 91; Chism, supra,
    58 Cal.4th at pp. 1326-1327.) Nor was it improper for the family members to
    testify that the nature of the murders made the aftermath especially difficult for
    them. (See People v. Montes, supra, 58 Cal.4th at p. 880 [finding no error where
    each of the ―relative[s] testified the unexpected and abrupt nature of [the victim‘s]
    death made it especially painful‖].) As a result, Simon has failed to show the trial
    court abused its discretion in concluding that the probative value of the victim
    impact evidence was not substantially outweighed by any risk of undue prejudice.
    2. Victim Impact Instructions
    Simon argues that the trial court failed to fulfill its sua sponte duty to
    properly instruct the jury as to victim impact evidence. We find no error.
    a. Background
    At the penalty phase, the trial court instructed jurors with a modified
    version of CALJIC No. 8.84.1: ―You will now be instructed as to all of the law
    that applies to the penalty phase of this trial. [¶] . . . [¶] You must determine what
    the facts are from the evidence received during the trial unless you are instructed
    otherwise. You must accept and follow the law that I state to you. You may
    consider pity, sympathy, or mercy for the defendant in determining the penalty in
    this case which you find to be warranted under the circumstances. [¶] You must
    neither be influenced by bias or prejudice against the defendant, nor swayed by
    public opinion or public feeling. Both the People and the defendant have the right
    to expect that you will consider all the evidence, follow the law, exercise your
    53
    discretion conscientiously, and reach a just verdict.‖ The trial court also instructed
    the jury with CALJIC No. 8.85.
    On appeal, Simon acknowledges that he ―did not request an instruction
    regarding the appropriate use of victim impact evidence.‖ He argues, however,
    that this failure did not absolve the trial court of its sua sponte duty to provide
    jurors with the guidance necessary for them to properly consider the victim impact
    evidence in the case. According to Simon, the trial court‘s failure to give an
    appropriate limiting instruction violated his ―right to a decision by a rational and
    properly-instructed jury, his due process right to a fair trial, and his right to a fair
    and reliable capital penalty determination‖ under the federal and state
    constitutions.
    Simon contends that an appropriate instruction, derived from State v.
    Koskovich, (N.J. 2001) 
    776 A.2d 144
    , 177, and Commonwealth v. Means, (Pa.
    2001) 
    773 A.2d 143
    , 159, would have been: ―Victim impact evidence is simply
    another method of informing you about the nature and circumstances of the crime
    in question. You may consider this evidence in determining an appropriate
    punishment. However, the law does not deem the life of one victim more valuable
    than another; rather, victim impact evidence shows that the victim, like the
    defendant, is a unique individual. Your consideration must be limited to a rational
    inquiry into the culpability of the defendant, not an emotional response to the
    evidence. Finally, a victim-impact witness is precluded from expressing an
    opinion on capital punishment and, therefore, jurors must draw no inference
    whatsoever by a witness‘s silence in that regard.‖
    b. Legal Standard
    In general, a defendant‘s failure to request a clarifying jury instruction
    forfeits any objection thereto. (People v. Russell (2010) 
    50 Cal.4th 1228
    , 1273;
    54
    see also People v. Arias (1996) 
    13 Cal.4th 92
    , 171 [―defendant‘s failure to request
    a clarifying instruction waives that claim‖]; People v. Rodrigues (1994) 
    8 Cal.4th 1060
    , 1192 [―if defendant believed the instruction was unclear, he had the
    obligation to request clarifying language. . . . [¶] . . . [¶] Defendant‘s failure to
    request such clarifications at trial bars appellate review of the issue‖].)
    Nonetheless, a trial court has a duty to instruct sua sponte ―on those general
    principles of law that are closely and openly connected with the facts before the
    court and necessary for the jury‘s understanding of the case.‖ (People v. Price
    (1991) 
    1 Cal.4th 324
    , 442.)
    c. Analysis
    Simon concedes that he failed to request a clarifying jury instruction
    pertaining to victim impact evidence. His claim, hence, is forfeited. (See People
    v. Russell, supra, 50 Cal.4th at p. 1273.)
    Simon argues nevertheless that the trial court had a sua sponte duty to
    deliver an appropriate limiting instruction akin to the one proposed above. We
    have rejected the same argument — and the exact same proposed instruction —
    before. Indeed, we have repeatedly held that the trial court‘s use of jury
    instructions CALJIC Nos. 8.84.1 and 8.85 is sufficient to address a defendant‘s
    concerns about the proper use of victim impact evidence, and is consistent with his
    or her federal and state constitutional rights to due process, a fair trial, and a
    reliable penalty determination. (See People v. Zamudio, supra, 43 Cal.4th at
    pp. 369-370; see also People v. Carrington (2009) 
    47 Cal.4th 145
    , 198 [―We
    previously have rejected these same contentions‖]; People v. Bramit (2009) 
    46 Cal.4th 1221
    , 1245 [―We recently considered this instruction and concluded it is
    neither required nor appropriate‖].)

    As the jury here was instructed according to CALJIC Nos. 8.84.1 and 8.85,
    and Simon offers no persuasive reason to revisit our prior rulings, we see no error.
    3. Prosecution Rebuttal Evidence
    Simon argues that the trial court committed reversible error by admitting
    irrelevant and highly prejudicial rebuttal evidence at the penalty phase. We are
    not persuaded.
    a. Background
    During the penalty phase, Simon presented expert witness testimony
    regarding his brain injuries, as well as testimony from his mother and relatives
    regarding his difficult childhood and their loving relationships with him. Simon‘s
    family members testified that he was a good role model, a ―disciplined young
    person,‖ and ―quite a good kid.‖ His cousin Richardson testified that Simon was
    supportive and helpful when she was pregnant. Simon‘s half sister also testified
    that Simon had given her good advice in the past, dissuading her from adopting a
    lifestyle of crime.
    At the close of the defense‘s case, the prosecution sought to introduce as
    rebuttal evidence a letter that Simon purportedly had written to his wife, Keisia,
    while incarcerated. The letter contained threatening and explicit language directed
    at Keisia, calling her ―bitch‖ and ―roadkill‖ and warning that Simon would ―get‖
    her. The prosecution argued that it was admissible to counter the evidence Simon
    had introduced of his good character. In particular, the letter was necessary to
    counter the defense evidence that Simon was ―a person of such character that he‘s
    important for his family members to maintain a relationship with him, maybe
    someone they can go to for advice.‖ Defense counsel objected to the letter‘s
    admission, stating: ―I haven‘t gone into [Simon‘s] character trait for violence.‖
    The trial court overruled this objection, and the letter was read to the jury.
    56
    Simon now contends that the trial court committed reversible error in
    admitting this evidence. This decision, he contends, violated his rights to have
    reasonable time limits placed on the admission of aggravating evidence, to receive
    due process and a fair trial, and to a reliable penalty determination. Simon asserts
    that because he did not introduce any evidence relating to his character for
    nonviolence, evidence showing his character for violence constituted improper
    rebuttal.
    b. Legal Standard
    When a defendant claims that his or her general character weighs in favor
    of mercy, a prosecutor is entitled to rebut that claim with evidence or argument
    offering a different account of the defendant‘s character. (See People v. Loker
    (2008) 
    44 Cal.4th 691
    , 709 [―When a defendant places his character at issue
    during the penalty phase, the prosecution is entitled to respond with character
    evidence of its own‖]; People v. Rodriguez (1986) 
    42 Cal.3d 730
    , 791.) If the
    defendant‘s good character evidence ―was not limited to any singular incident,
    personality trait, or aspect of his background‖ and ―painted an overall picture of an
    honest, intelligent, well-behaved, and sociable person incompatible with a violent
    or antisocial character,‖ the prosecution may introduce appropriate rebuttal
    evidence of the scope offered. (People v. Mitcham (1992) 
    1 Cal.4th 1027
    , 1072.)
    But that scope must still be specific, as we have rejected the idea that any evidence
    introduced for the defendant‘s good character will open the door to any and all bad
    character evidence from the prosecution. (People v. Rodriguez, supra, 42 Cal.3d
    at p. 792, fn. 24.)
    A trial court has broad discretion when determining the admissibility of
    rebuttal evidence, and we review a trial court‘s decision to admit such evidence for
    abuse of discretion. (See People v. Valdez (2012) 
    55 Cal.4th 82
    , 170 [―absent
    57
    palpable abuse, an appellate court may not disturb the trial court‘s exercise of that
    discretion‖].)
    c. Analysis
    Admitting the letter here was not an abuse of discretion. The vile,
    threatening language Simon employed in the letter to his wife undermined the
    defense‘s evidence that Simon was supportive of the women in his life and was
    someone they could turn to for sound advice. The letter‘s menacing language —
    including repeated threats to Keisia‘s life — suggested that Simon possessed
    negative, aggressive attitudes toward women that stood in stark contrast to the
    testimony of his positive character attributes.
    Our decision in People v. Rodriguez, supra, 
    42 Cal.3d 730
    , is instructive.
    There, we affirmed the ability of the prosecutor to rebut evidence of the
    defendant‘s general character. (Id. at p. 791.) The prosecutor referred to an
    incident where the defendant had supposedly reached for a sawed-off shotgun in
    the back seat during a traffic stop. (Id. at pp. 745, 791.) We held that the incident
    was properly admitted, as it rebutted evidence that the defendant ―was a kind,
    loving, contributive member of his community, regarded with affection by
    neighbors and family.‖ (Id. at p. 791.) Similarly, the defense evidence here
    sought to portray Simon as a kind individual who was supportive of the women in
    his life. The letter refuted that portrayal.
    As the letter, though sharply worded, was relatively short in comparison to
    the good character evidence the defense had offered, and because it pertained
    directly to that evidence, we conclude the trial court did not abuse its discretion in
    allowing it.
    58
    4. Reference to Other Murder Cases
    Simon claims that the trial court violated his rights to counsel and due
    process at the penalty phase by refusing to allow defense counsel to refer to other
    prominent murder cases during closing argument. We disagree.
    a. Background
    During closing argument, defense counsel urged the jury when considering
    whether Simon deserved the death penalty to ―put him in that category of
    convicted offenders of special circumstances murder, and then evaluate whether
    he‘s the worst in that — or among the worst in that category.‖ Using a pyramid
    graphic to illustrate the different categories of murder, defense counsel argued that
    only a narrow group of people liable for a special circumstances murder qualify
    for the death penalty. Defense counsel then referred to the murderers Timothy
    McVeigh and Charles Manson as points of comparison for the jurors to consider
    when deciding if Simon deserved to die. After hearing this remark, the prosecutor
    objected.
    During a discussion outside the jury‘s presence, the trial court stated, ―I
    think the comparison argument need be made to a point, up to the point to where
    we‘re talking about first degree murders are not available for death penalty,‖ but it
    expressed concerns with comparing first degree murders with special
    circumstances. The prosecutor contended that defense counsel‘s argument that
    Simon was ―not as bad as‖ Timothy McVeigh and Charles Manson was improper
    because the penalty phase requires an individual determination based on the
    defendant‘s own crime and background. The prosecutor cited People v. Jenkins
    (2000) 
    22 Cal.4th 900
    , 1052 to support the proposition that under section 190.3,
    factor (a), a jury‘s consideration of the circumstances of the crime committed must
    be individualized, not comparative. The court sustained the objection, agreeing
    with the prosecutor that ―[i]t comes down to an individual determination of guilt
    59
    and not a comparative balancing of whether or not [Simon‘s] crime is worse than
    Timothy McVeigh‘s.‖ The court did not, however, give a curative instruction to
    the jury.
    On appeal, Simon relies on People v. Millwee (1998) 
    18 Cal.4th 96
    , 153 to
    show that during penalty phase closing argument counsel may discuss ―other cases
    and crimes in order to assist jurors in exercising sentencing discretion.‖ Simon
    suggests that trial courts may only limit the scope of defense counsel‘s closing
    argument when that argument would be overly time consuming. Further, Simon
    contends that because the trial court here based its ruling on an incorrect
    interpretation of law, its limitation cannot be an appropriate exercise of discretion.
    Simon maintains that these alleged errors were prejudicial and ―skewed the
    weighing process in favor of the prosecution,‖ resulting in the denial of Simon‘s
    rights to due process, a fair trial, effective assistance of counsel, and a reliable
    penalty determination.
    b. Legal Standard
    Criminal defendants enjoy a constitutional right to have counsel present
    closing argument to the trier of fact. (People v. Benavides (2005) 
    35 Cal.4th 69
    ,
    110; see Herring v. New York (1975) 
    422 U.S. 853
    , 858 [―There can be no doubt
    that closing argument for the defense is a basic element of the adversary
    factfinding process in a criminal trial‖].) This right, however, is subject to certain
    limits. (People v. Benavides, supra, at p. 110.) A trial court may impose
    reasonable time limits and may ensure that argument does not ―stray unduly from
    the mark.‖ (People v. Marshall (1996) 
    13 Cal.4th 799
    , 854-855.) Trial courts
    have broad discretion to control the duration and scope of closing arguments. (See
    Herring v. New York, 
    supra, at p. 862
     [―In all these respects [the trial court] must
    have broad discretion‖].)
    60
    We review a trial court‘s decision to limit defense counsel closing
    argument for abuse of discretion. (See People v. Rodrigues, 
    supra,
     8 Cal.4th at
    p. 1184.)
    c. Analysis
    On numerous occasions, we have upheld a trial court‘s refusal to allow
    defense counsel to compare the defendant to specific well-known murderers or
    their crimes. (See, e.g., People v. Virgil (2011) 
    51 Cal.4th 1210
    , 1285-1287;
    People v. Hughes (2002) 
    27 Cal.4th 287
    , 399-400; People v. Roybal (1998) 
    19 Cal.4th 481
    , 528-529 (Roybal); People v. Marshall, 
    supra,
     13 Cal.4th at pp. 853-
    855.) So long as the defendant is allowed to ―make his central point and to argue
    in general terms that there were ‗worse cases‘ than his,‖ the trial court‘s refusal is
    within its broad discretion. (People v. Hughes, at p. 400.) As relevant to the
    present case, we have held that a trial court‘s instruction that jurors may not
    compare the defendant‘s crime with any other crime does not constitute prejudicial
    error. (Roybal, at p. 529.)
    As an initial matter, we disagree with Simon‘s suggestion that a trial court
    may only limit defense counsel‘s closing argument if it is overly time consuming.
    To the contrary, trial courts have ―broad discretion‖ to limit both the duration and
    scope of closing arguments. (Herring v. New York, 
    supra,
     422 U.S. at p. 862.)
    Thus, the trial court‘s decision to preclude Simon‘s defense counsel from making
    specific references to well-known murderers need not be based on time
    considerations only.
    We also disagree with Simon‘s contention that the trial court improperly
    limited defense counsel during closing argument. The trial court‘s refusal to allow
    defense counsel to compare Simon‘s crimes with the murders committed by the
    likes of Timothy McVeigh and Charles Manson was well within its broad
    61
    discretion. (See People v. Virgil, supra, 51 Cal.4th at pp. 1285-1287 [finding no
    abuse of discretion where trial court prohibited defense counsel from referencing
    prosecutions of O.J. Simpson and the Menendez brothers].)
    We upheld a similar limitation in People v. Farley (2009) 
    46 Cal.4th 1053
    (Farley). In Farley, the defendant argued that the trial court erred by prohibiting
    defense counsel from arguing at closing that the defendant‘s crimes were not as
    bad as other capital defendants. (Id. at pp. 1129-1130.) Defense counsel sought to
    refer to infamous murderers like Richard Ramirez, David Carpenter, and Ramon
    Salcido. (Id. at p. 1130.) But the trial court ―ruled that counsel would ‗not be
    permitted to engage in a comparative analysis of other death penalty cases or other
    murder cases . . . .‘ ‖ (Ibid.) While the trial court barred defense counsel from
    mentioning specific cases, names, and penalties, it permitted counsel to argue
    ― ‗this is not a child torture case or something like that.‘ ‖ (Ibid.) We upheld the
    trial court‘s refusal, explaining that counsel was not precluded from making his
    central point that the ―defendant‘s murders were not ‗the worst of the worst.‘ ‖
    (Id. at p. 1131.) The same is true here. Although the trial court below did not
    allow defense counsel to mention specific names, defense counsel was still
    permitted to ask the jury to consider if Simon was among the worst in the category
    of convicted offenders of special-circumstances murder. As in Farley, then, we
    find no constitutional violation.
    Nor would we likely have found such a violation had the trial court
    instructed the jury against comparing Simon‘s crimes to any others. (See Roybal,
    
    supra,
     19 Cal.4th at pp. 528-529.) In Roybal, defense counsel sought to compare
    the defendant‘s case to the so-called ―Billionaire Boys Club‖ murders. (Id. at
    p. 528.) The trial court sustained an objection by the prosecutor and instructed
    jurors, ― ‗[Y]ou may not attempt to compare this crime, this murder, with any
    other murder. In other words, you can‘t indulge in comparisons. . . . You focus on
    62
    the facts associated with this case, with this defendant, with this crime.‘ ‖ (Ibid.,
    italics added.) We upheld the trial court‘s instruction, reasoning that the defendant
    could still argue his central point that the circumstances of his crime were
    mitigated by his background and emotional and mental disorders. (Id. at p. 529.)
    Here, as in Roybal, Simon‘s defense counsel was not precluded from
    making his central argument that not every person (Simon included) found liable
    for special circumstances murder deserves the death penalty. And even had the
    trial court admonished the jury with a curative instruction following defense
    counsel‘s comparative references — which the court did not do — Roybal
    demonstrates that such an instruction would likely have been proper. (Roybal,
    supra, 19 Cal.4th at p. 529.) Thus, the trial court‘s decision here did not constitute
    an abuse of discretion.
    5. Other Challenges to the Death Penalty Statute
    Simon raises numerous challenges to California‘s death penalty scheme
    that we have repeatedly considered and rejected. He fails to persuade us to
    reconsider our previous holdings. As a result, we again conclude:
    The death penalty is not unconstitutional for failing broadly to ―adequately
    narrow the class of murderers eligible for the death penalty.‖ (Bryant, Smith and
    Wheeler, supra, 60 Cal.4th at p. 468.) Section 190.3, factor (a), which permits the
    jury to consider the circumstances of a defendant‘s crime in determining whether
    to impose the death penalty, does not license the jury to impose death in an
    arbitrary and capricious manner in violation of the Fifth, Sixth, Eighth, and
    Fourteenth Amendments to the United States Constitution. (People v. Boyce
    (2014) 
    59 Cal.4th 672
    , 723 (Boyce); People v. Enraca (2012) 
    53 Cal.4th 735
    ,
    769.)
    63
    Nor is the death penalty unconstitutional ―for failing to require proof
    beyond a reasonable doubt that aggravating factors exist, outweigh the mitigating
    factors, and render death the appropriate punishment.‖ (Boyce, supra, 59 Cal.4th
    at pp. 723-724.) This conclusion is not altered by the United States Supreme
    Court‘s decisions in Apprendi v. New Jersey (2000) 
    530 U.S. 466
    , and Ring v.
    Arizona (2002) 
    536 U.S. 584
    . (Boyce, at p. 724.) Neither does the federal
    Constitution require that the jury make written findings regarding aggravating
    factors. (People v. DeHoyos (2013) 
    57 Cal.4th 79
    , 150.)
    Section 190.3 does not require California courts to undertake a comparison
    between the case at bar and other similar cases with respect to the relative
    proportionality of the sentence imposed. Nor does the federal Constitution
    mandate such intercase proportionality review. (People v. Contreras (2013) 
    58 Cal.4th 123
    , 173.)
    During the penalty phase, the jury may consider a defendant‘s
    unadjudicated criminal activity and need not unanimously agree beyond a
    reasonable doubt that such criminal activity occurred. (People v. Nelson, 
    supra,
    51 Cal.4th at p. 226.)
    The use of adjectives such as ―extreme‖ and ―substantial‖ in the list of
    potential mitigating factors in section 190.3 does not unconstitutionally obstruct
    the jury‘s ability to consider mitigating evidence. (People v. Martinez (2010) 
    47 Cal.4th 911
    , 968; see Boyce, supra, 59 Cal.4th at p. 724.) Moreover, the trial
    court ―need not instruct the jury that mitigating factors can be considered only in
    mitigation.‖ (Boyce, at p. 724.)
    California does not deny capital defendants equal protection of the law by
    providing certain procedural protections to noncapital defendants that are not
    afforded to capital defendants. (People v. Williams (2013) 
    58 Cal.4th 197
    , 295.)
    64
    International norms and treaties do not render the death penalty
    unconstitutional as applied in this state. (People v. Williams, supra, 58 Cal.4th at
    pp. 295-296.)
    Finally, the cumulative impact of these purported deficiencies in
    California‘s death penalty scheme does not render the penalty unconstitutional.
    We have rejected each of Simon‘s challenges to the death penalty statute, and
    these challenges are no more persuasive when considered together. (See People v.
    Williams, supra, 58 Cal.4th at p. 296; People v. Garcia (2011) 
    52 Cal.4th 706
    ,
    764-765.)
    65
