    Opinion for the Court filed PER CURIAM.
    PER CURIAM: The Hostage Taking Act, 18 U.S.C. § 1203,
    prescribes criminal penalties for foreign nationals who abduct
    American citizens. In this case, nationals of the Republic of
    3
    Trinidad and Tobago abducted wealthy individuals, held them
    captive in the island’s mountainous forests, and extorted
    ransoms from terrified family and friends. The scheme
    proved quite profitable—at least until they kidnapped an
    American citizen and ran headlong into the Hostage Taking
    Act. The conspirators were extradited to the United States,
    tried, and convicted of violating the Act. But does that statute
    apply if, as defendants allege, the victim secured his United
    States citizenship through fraud? The district court held that it
    does, and for the reasons set forth in this opinion, we agree.
    Rejecting all of the conspirators’ other challenges, we affirm
    their convictions in all respects.
    I.
    By early 2005, defendants Wayne Pierre, Ricardo De
    Four, and Zion Clarke had perfected their hostage-taking
    protocol and regularly extorted six-figure ransoms
    (Trinidadian dollars). Looking to up the ante, the three
    enlarged their organization to include defendants Kevon
    Demerieux, Kevin Nixon, Christopher Sealey, and Anderson
    Straker, and set their sights on Trinidad-native Balram
    Maharaj, whom they believed had amassed a fortune in the
    United States. Although naturalized as an American citizen in
    1995, Maharaj frequently visited his children in Trinidad.
    Defendants, assisted by a host of unindicted co-conspirators,
    planned to abduct Maharaj during one of those visits.
    On the night of April 6, 2005, defendants executed their
    plan. Sealey and Nixon, armed with handguns, dragged
    Maharaj from Samaan Tree Bar in Aranguez, Trinidad and
    forced him into a getaway car while De Four drove ahead in a
    separate vehicle to clear the way. Sealey and Nixon delivered
    Maharaj to an isolated camp deep within the forest where
    Clarke and Demerieux guarded him. A nightmare ensued.
    4
    The two guards tied Maharaj to a post and gave him little
    food and water. Suffering from severe diabetes, hypertension,
    and tuberculosis, Maharaj pleaded for medication. Clarke and
    Demerieux ignored his pleas while their co-conspirator,
    Winston Gittens, used Maharaj’s worsening health as leverage
    to demand three million Trinidadian dollars from his family.
    Bound and gagged, Maharaj repeatedly refused defendants’
    attempts to record a “proof of life” video, even when Straker
    threatened to harm Maharaj’s son. After six days in captivity,
    Maharaj slipped into a diabetic coma and died.
    Well aware that they had killed a United States citizen,
    defendants voted to conceal their crime. “No body, no
    evidence, no case,” proclaimed Pierre. Using a machete and
    their bare hands, Clarke, Demerieux, and Pierre removed
    Maharaj’s internal organs and dismembered his body. They
    packed the remains in Styrofoam containers and buried them in
    the woods.      As with most buried secrets, however,
    defendants’ misdeeds eventually surfaced.
    In late 2005, the Trinidad and Tobago Police Service
    began an investigation of defendants’ hostage-taking ring.
    Assisted by the FBI, Trinidadian police ultimately uncovered
    evidence of Maharaj’s death. The United States extradited
    defendants and charged them with conspiracy and
    hostage-taking resulting in death in violation of the Hostage
    Taking Act. The facts and circumstances surrounding the
    kidnapping are largely undisputed—indeed, five of the seven
    defendants confessed.         Defendants primarily argue that
    Maharaj misrepresented key facts on his immigration
    applications, thus negating his United States citizenship—an
    essential element of a Hostage Taking Act prosecution. The
    district court rejected this argument, as well as numerous other
    objections. After a ten-week trial, the jury convicted
    5
    defendants of all charges, and the district court sentenced them
    to life imprisonment without the possibility of release.
    Defendants now appeal their convictions on numerous
    grounds. We address the arguments pertaining to Maharaj’s
    citizenship in Part II and then consider defendants’ other
    arguments in Parts III through XI.
    II.
    Enacted to fulfill the United States’ obligations under the
    International Convention Against the Taking of Hostages, the
    Hostage Taking Act, 18 U.S.C. § 1203, makes extraterritorial
    hostage-taking a criminal offense when the victim is a United
    States national. On appeal, it is undisputed that at the time of
    his death Balram Maharaj possessed an authentic certificate of
    naturalization.
    Before trial, however, defendants uncovered evidence
    they claim demonstrates that Maharaj obtained his
    naturalization through fraud. According to this evidence,
    Maharaj, formerly Aladdin Barlow John, first entered the
    United States in 1967 as a non-immigrant transit en route to
    Canada. Following a short visit there, Maharaj returned to the
    United States, briefly settling in New York before enlisting in
    the Army in 1968. He deserted seven months later. In order
    to avoid prosecution for desertion, Maharaj completed a
    clemency program and was ultimately discharged from the
    Army as undesirable.
    In April 1986, the Immigration and Naturalization Service
    (INS), having discovered that Maharaj had overstayed his 1967
    transitory permit, ordered him to leave the United States. But
    instead of leaving, he petitioned INS for permanent-resident
    alien status, also known as a green card. Asked on his green
    6
    card application whether he had ever been convicted of a crime
    involving moral turpitude, Maharaj checked “no” even though,
    defendants claim, he had once pleaded guilty to petty larceny
    and was on probation. Maharaj also checked “no” when
    asked whether he had ever suffered an “attack of insanity,”
    narcotic drug addiction, or chronic alcoholism, even though his
    ex-wife would years later attest in an unrelated proceeding that
    he had previously spent time in a mental-health facility,
    attempted suicide, and chronically abused alcohol and
    prescription drugs. INS granted Maharaj’s petition.
    After maintaining permanent-resident status for five years,
    Maharaj applied for full naturalization in 1994. On the
    application, Maharaj checked “no” when asked whether he had
    ever been ordered deported. And when asked whether he had
    ever knowingly committed a crime for which he had not been
    arrested, he checked “no” even though his ex-wife had testified
    that he once physically assaulted and raped her. INS granted
    Maharaj citizenship in 1995.
    The question whether Maharaj’s misrepresentations
    negated his citizenship and, in turn, defendants’ guilt, was the
    most contested issue throughout the proceedings in the district
    court. Defendants first raised the issue in a motion to dismiss
    the indictment, arguing that because conviction under the
    Hostage Taking Act requires U.S. citizenship and because
    Maharaj’s fraud negated his citizenship, the district court
    lacked jurisdiction. The district court disagreed. Citing a
    long and unbroken line of Supreme Court precedent, see, e.g.,
    United States v. Zucca, 
    351 U.S. 91
    , 95 & n.8 (1956); see also
    Bindczyck v. Finucane, 
    342 U.S. 76
    , 83 (1951), the district
    court held that 8 U.S.C. § 1451, which permits the United
    States Attorney to institute denaturalization proceedings in a
    federal district court, is the exclusive procedure for voiding the
    citizenship of a person naturalized due to fraud. United States
    7
    v. Clarke, 
    628 F. Supp. 2d 1
    , 9 (D.D.C. 2009). Citizenship,
    the court held, remains valid until a district court, acting upon a
    United States Attorney’s section 1451 motion, determines that
    naturalization was “procured by concealment of a material fact
    or fraud.” 
    Id. at 6
    (quoting 8 U.S.C. § 1451(a)). Given that
    no district court had ever made such a finding as to Maharaj,
    the court denied the motion. 
    Clarke, 628 F. Supp. 2d at 10
    .
    The district court also granted the government’s motion in
    limine to exclude from trial any evidence regarding Maharaj’s
    alleged fraud. 
    Id. at 13.
    Conviction under the Hostage
    Taking Act, the court held, requires the government to prove
    that the victim acquired citizenship by birth or naturalization.
    
    Id. at 13.
    Evidence disputing whether the victim should have
    been naturalized or the circumstances surrounding
    naturalization is irrelevant. 
    Id. The court
    therefore rejected
    defendants’ argument that they had a Sixth Amendment right
    to present evidence regarding Maharaj’s alleged fraud to the
    jury. 
    Id. at 14.
    “[T]he jury,” the district court concluded,
    “may not decide the validity of Maharaj’s citizenship.” 
    Id. at 13.
    At trial, the government offered Maharaj’s certificate of
    naturalization and two passports as evidence of his citizenship.
    An employee of the U.S. Citizenship and Immigration Service
    testified that INS issued the certificate of naturalization in
    1995. A State Department Fraud Program Manager testified
    that Maharaj’s two passports, issued in 1995 and 2000, were
    authentic. On cross examination, however, defense counsel
    pointed out that Maharaj’s 1995 passport was unsigned and, as
    the witness conceded, invalid. See 22 C.F.R. § 51.4(a) (“A
    passport book is valid only when signed by the bearer in the
    space designated for signature[.]”). The district court struck
    the 1995 passport from evidence and ruled that challenges to
    the authenticity of the 2000 passport, issued solely on the basis
    8
    of the stricken 1995 passport, were fair game. In sum, then,
    the district court permitted defendants to argue that the
    citizenship documents were inauthentic, i.e., forged or
    counterfeit, but barred them from collaterally attacking INS’s
    decision to naturalize Maharaj.
    In its final instructions, the district court reminded the jury
    that the victim’s citizenship was an essential element of the
    crime that the government must prove beyond a reasonable
    doubt. The 2000 passport and the naturalization certificate,
    the court instructed, may be considered as evidence of
    citizenship. In closing arguments, defense counsel pressed
    this point, claiming that the invalidity of the 1995 passport
    called into question the authenticity of the 2000 passport, as
    well as the naturalization certificate.
    After the jury returned a guilty verdict, defendants,
    reiterating their earlier arguments, moved for a judgment of
    acquittal, or alternatively a new trial. Relying on its prior
    reasoning, the district court denied the motion. United States
    v. Clarke, 
    767 F. Supp. 2d 12
    , 65 (D.D.C. 2011).
    The criminal trial was not the only forum in which
    defendants challenged Maharaj’s citizenship. Prior to trial,
    defendants submitted affidavits to the United States Attorney
    for the District of Columbia detailing Maharaj’s alleged fraud
    and requesting initiation of section 1451 proceedings. When
    the U.S. Attorney took no action, defendants petitioned the
    district court for a writ of mandamus requiring the U.S.
    Attorney to initiate denaturalization proceedings.            The
    government moved to dismiss pursuant to Federal Rules of
    Civil Procedure 12(b)(1) for lack of jurisdiction and 12(b)(6)
    for failure to state a claim. The district court granted the Rule
    12(b)(1) motion, finding that defendants lacked constitutional
    standing because they failed to demonstrate that their requested
    9
    remedy—initiation of section 1451 proceedings—would
    redress their claimed injury, i.e., denial of the right to present
    evidence in the criminal trial. It is “wholly speculative,” the
    court concluded, whether the U.S. Attorney could meet the
    high burden of proof necessary to denaturalize Maharaj,
    “especially in light of evidentiary problems that may arise so
    long after Maharaj’s death and his inability to defend himself.”
    Clarke v. Holder, 
    767 F. Supp. 2d 106
    , 109 (D.D.C. 2011).
    Alternatively, the district court found that even if defendants
    could establish standing, they failed to meet the threshold
    requirements for mandamus relief because the U.S. Attorney
    had no clear duty to seek posthumous denaturalization of
    Maharaj. 
    Id. at 112–13.
    On appeal, defendants argue that the district court lacked
    jurisdiction under the Hostage Taking Act and erred in
    excluding evidence contesting the validity of Maharaj’s
    naturalization. Defendants also appeal the district court’s
    denial of their petition for a writ of mandamus. We address
    each issue in turn.
    The Criminal Conviction
    Defendants argue that “[s]ubject matter jurisdiction . . .
    hinges entirely on Mr. Maharaj’s citizenship.” Def. Br. 12.
    This, however, misapprehends the nature of federal court
    jurisdiction in criminal cases. A claim that an element of the
    offense is unsatisfied—that the victim was not a United States
    citizen, for example—goes only to a defendant’s guilt or
    innocence. In other words, jurisdiction hinges not on the
    merits, but rather on the court’s constitutional or statutory
    power to adjudicate the case. Lamar v. United States, 
    240 U.S. 60
    , 64 (1916) (“Jurisdiction is a matter of power, and
    covers wrong as well as right decisions.”). Under 18 U.S.C.
    § 3231, federal district courts possess statutory authority over
    10
    “all offenses against the laws of the United States.” Because
    violation of the Hostage Taking Act is an offense against the
    laws of the United States, our jurisdictional inquiry ends and
    we turn to the merits of defendants’ appeal. United States v.
    Fahnbulleh, 
    752 F.3d 470
    , 476 (D.C. Cir. 2014) (“If an
    indictment or information alleges the violation of a crime set
    out in Title 18 or in one of the other statutes defining federal
    crimes, that is the end of the jurisdictional inquiry.”) (internal
    quotation marks omitted).
    Defendants make two arguments. They first claim that
    the district court’s exclusion of evidence regarding Maharaj’s
    alleged fraud violated their constitutional right to present a
    complete defense. They also argue that the district court
    removed the citizenship question from the jury, thus relieving
    the government of its burden to prove Maharaj’s citizenship
    beyond a reasonable doubt.
    With respect to both arguments, our starting point is the
    text of the Hostage Taking Act. Section 1203(b)(1)(A)
    criminalizes hostage-taking that occurs outside the United
    States if “the person seized or detained is a national of the
    United States.” A “national of the United States” is, in turn,
    defined by reference to the Immigration and Nationality Act as
    “a citizen of the United States.” 18 U.S.C. § 1203(c); 8 U.S.C.
    § 1101(a)(22). By its plain language, then, section 1203
    broadly protects United States citizens. The statute imposes
    no restriction on this protection. It does not, for example,
    exclude citizens who, in retrospect, are unworthy of the honor.
    Nor does it exclude persons whose citizenship might at some
    later time be invalidated. In other words, section 1203
    protects victims according to their status at the time of the
    hostage-taking.
    11
    True, section 1203 is written in the present tense—the
    statute applies if “the person seized or detained is a national of
    the United States.” But that clause appears in a criminal
    statute that requires examination of past events—whether the
    victim was seized or detained. See Cullen v. Pinholster, 
    131 S. Ct. 1388
    , 1398 (2011) (use of backward-looking language
    such as “resulted in” and “involved” in federal habeas statute,
    28 U.S.C. § 2254(d), requires examination of the state-court
    decision at the time it was made). A more familiar statute, the
    Armed Career Criminal Act, provides a helpful parallel. The
    ACCA imposes a sentence enhancement if the defendant “has
    three previous convictions . . . for . . . serious drug offense[s]”
    for which “a maximum term of imprisonment of ten years or
    more is prescribed by law.” 18 U.S.C. § 924(e) (emphasis
    added). As the Supreme Court has explained, “[t]he plain text
    of ACCA” therefore “requires the court to determine whether a
    ‘previous conviction’ was for a serious drug offense.” McNeill
    v. United States, 
    131 S. Ct. 2218
    , 2221–22 (2011) (emphases
    added). To answer that “backward-looking question,” the
    Court held that the sentencing court must “consult the law that
    applied at the time of that conviction.” 
    Id. at 2222.
    So too
    here. Determining whether an American citizen was seized or
    detained under the Hostage Taking Act requires examination
    of the victim’s status at the time of the abduction.
    This focus on status at the time of the crime is hardly
    unusual. For instance, convictions under the federal statute
    that bars felons from possessing firearms rest solely upon the
    fact of the prior felony. Lewis v. United States, 
    445 U.S. 55
    ,
    62–65 (1980). The validity of the prior conviction is
    irrelevant even when that conviction is patently
    unconstitutional. Id.; see also Custis v. United States, 
    511 U.S. 485
    , 493–97 (1994) (defendants in federal sentencing
    proceedings may not, with a narrow exception for certain
    convictions obtained in violation of the right to counsel,
    12
    challenge the validity of prior state convictions used to
    enhance sentences under the Armed Career Criminal Act).
    Likewise, defendants accused of providing material support to
    designated foreign terrorist organizations in violation of 18
    U.S.C. § 2339B may not challenge the validity of the
    designation. United States v. Hammoud, 
    381 F.3d 316
    , 331
    (4th Cir. 2004) (en banc) (“Congress has provided that the fact
    of an organization’s designation as an FTO is an element of
    § 2339B, but the validity of the designation is not.”), rev’d on
    other grounds, 
    543 U.S. 1097
    (2005); see also United States v.
    Mandel, 
    914 F.2d 1215
    , 1222 (9th Cir. 1990) (defendants
    charged with illegally exporting items on the Secretary of
    Commerce’s Commodity Control List may not challenge the
    validity of the Secretary’s designation).
    Finally, our interpretation of the Hostage Taking Act
    reinforces its purpose. When President Reagan proposed the
    bill that ultimately became the Act, he declared that it would
    “send a strong and vigorous message to friend and foe alike
    that the United States will not tolerate terrorist activity against
    its citizens[.]”     President’s Message to the Congress
    Transmitting Proposed Legislation to Combat International
    Terrorism, Pub. Papers, Admin. of Ronald Reagan 3–4 (Apr.
    26, 1984). This “strong and vigorous message” would be
    severely diluted if foreign nationals could target American
    citizens for abduction and then avoid prosecution in the United
    States by impugning the victim’s character. This is especially
    true where, as here, defendants targeted the victim not only
    because he was an American, but also because he had assets in
    the United States. Permitting them to escape prosecution by
    arguing that Maharaj was undeserving of United States
    citizenship would weaken the protection Congress intended to
    extend to Americans abroad.
    13
    For all of these reasons, the district court properly
    excluded evidence of Maharaj’s alleged fraud as irrelevant.
    Congress has vested sole naturalization authority in the
    Attorney General, 8 U.S.C. § 1421(a), and a certificate of
    naturalization represents conclusive evidence of the Attorney
    General’s determination, Tutun v. United States, 
    270 U.S. 568
    ,
    577 (1926); 8 U.S.C. § 1443(e). As explained above, whether
    the Attorney General, acting through INS, should have issued a
    certificate to Maharaj—as opposed to whether the certificate
    was itself authentic—is irrelevant under the Hostage Taking
    Act.
    The Mandamus Proceedings
    This brings us to defendants’ appeal of the district court’s
    denial of their petition for a writ of mandamus requiring the
    United States Attorney to initiate posthumous denaturalization
    proceedings against Maharaj under 8 U.S.C. § 1451. Recall
    that the district court denied the petition on the grounds that
    defendants lacked standing and, alternatively, that they failed
    to meet the requirements for mandamus relief. Clarke v.
    Holder, 
    767 F. Supp. 2d 106
    , 116 (D.D.C. 2011). Because we
    agree with the former ruling, we need not address the latter.
    In order to have Article III standing to bring their
    mandamus action, defendants must prove that they suffered (1)
    an “injury in fact” that is (2) “fairly . . . traceable to the
    challenged action,” and that is (3) likely to be “redressed by a
    favorable decision.” Lujan v. Defenders of Wildlife, 
    504 U.S. 555
    , 560–61 (1992) (internal quotation marks omitted). The
    district court found that defendants failed to establish the third
    element, redressability, i.e., “a substantial likelihood that the
    relief requested will redress the injury claimed.” Duke Power
    Co. v. Carolina Envtl. Study Grp., Inc., 
    438 U.S. 59
    , 75 n.20
    (1978) (internal quotation marks omitted).            Reviewing
    14
    defendants’ evidence, the district court thought it “wholly
    speculative” whether the government could meet section
    1451’s burden of proving fraud by “clear, unequivocal, and
    convincing evidence.” 
    Clarke, 767 F. Supp. 2d at 109
    , 112
    (quoting Fedorenko v. United States, 
    449 U.S. 490
    , 505
    (1981)). Given this, defendants’ alleged “injury—their
    hostage taking convictions—is not redressable by an order
    directing [the government] to initiate [a section 1451]
    proceeding.” 
    Clarke, 767 F. Supp. 2d at 109
    .
    Defendants challenge the district court’s conclusion on
    two grounds. First, they claim that their “injury is the lack of
    opportunity to present a defense,” which is “necessarily . . .
    redressed if the Government is compelled to bring a § 1451
    hearing against Mr. Maharaj.” Def. Mandamus Br. 9.
    Second, they argue that the district court’s evidentiary rulings
    in the criminal trial, together with its dismissal of their
    mandamus petition, ensnare them in a catch-22: defendants
    “could not show the citizenship evidence at trial because the
    district court had ruled that a Government-initiated § 1451
    proceeding was the exclusive avenue for presenting such
    evidence, but they could not present the evidence in a § 1451
    proceeding because the district court would not allow them to
    challenge the Government’s inaction.” 
    Id. at 8.
    Both arguments are foreclosed by the conclusion we
    reached in the previous section, i.e., that conviction under the
    Hostage Taking Act depends upon the victim’s citizenship at
    the time of the crime. Balram Maharaj possessed American
    citizenship when defendants abducted him in 2005. Whatever
    happens now is irrelevant. In other words, even if the
    government were to strip Maharaj of his United States
    citizenship under section 1451, defendants’ convictions would
    stand because Maharaj possessed a valid naturalization
    certificate at the time of the crime. Defendants’ alleged injury
    15
    is therefore incapable of redress not because the outcome of the
    section 1451 proceeding is too speculative (as the district court
    found), but because the outcome of those proceedings could
    not possibly affect defendants’ right to present a full defense to
    a charge under the Hostage Taking Act.
    We reach this conclusion despite section 1451’s
    relation-back provision, which provides that denaturalization
    on account of fraud “shall be effective as of the original date of
    the [naturalization] order and certificate.” 8 U.S.C. § 1451(a).
    Based on this provision and pre-section 1451 case law
    espousing the relation-back principle, defendants argue that
    denaturalization on account of Maharaj’s fraud would
    retroactively void his naturalization, meaning that he never
    possessed citizenship and thus was not a national under the
    Hostage Taking Act. Def. Mandamus Br. 11 n.8.
    The Supreme Court, however, has rejected mechanical
    application of section 1451’s relation-back principle.
    Costello v. Immigration and Naturalization Service, 
    376 U.S. 120
    , 130 (1964). In Costello, the Court examined section
    1451’s language and legislative history to determine whether
    the provision applied to the “general deportation provisions” of
    the Immigration and Nationality Act. 
    Id. at 129.
    The Court
    concluded that Congress intended the relation-back provision
    simply to codify pre-existing case law that retroactively voided
    fraudulently-acquired naturalization for the purpose of
    determining derivative citizenship, i.e., citizenship conveyed
    to children through the naturalization of one or both parents.
    
    Id. Calling relation-back
    a “legal fiction,” the Court refused,
    absent express congressional command, to extend that fiction
    to require deportation of a denaturalized individual on the
    theory that crimes committed prior to his denaturalization
    rendered him an alien despite possession of a then-valid
    naturalization certificate. 
    Id. at 130,
    132.
    16
    Likewise, nothing in the text or legislative history of
    section 1451—or the Hostage Taking Act—suggests that
    Congress intended the relation-back doctrine to apply in a
    criminal prosecution. Indeed, as explained above, applying
    the doctrine in this context would weaken the purpose of the
    Hostage Taking Act. See supra at 11. We therefore decline,
    as did the Supreme Court in Costello, to extend the legal fiction
    of relation-back into the realm of criminal law. See 
    Costello, 376 U.S. at 130
    .
    III.
    Objections to Introduction of Evidence of Other Crimes
    Defendants challenge the district court’s admission, over
    their repeated objections, of evidence of three other, uncharged
    hostage takings that occurred within four months of the
    Maharaj hostage taking. 1 We conclude that the district court
    did not err in admitting that evidence. It was relevant under
    Rule 404(b) as background showing how the conspiracy
    1
    All defendants, with the exception of Straker, state in a footnote in
    their brief their intention to join this argument. Def. Br. 29 n.9.
    While adoption by reference pursuant to Federal Rule of Appellate
    Procedure 28(i) may streamline the appeal of common legal issues, it
    threatens to confuse those issues that litigants do not share. See
    United States v. Renteria, 
    720 F.3d 1245
    , 1251 (10th Cir. 2013),
    cert. denied, 
    134 S. Ct. 969
    (2014); United States v. Santana-Pérez,
    
    619 F.3d 117
    , 122 (1st Cir. 2010). The evidence of other crimes
    was admitted only against Pierre, De Four, and Clarke. The
    remaining defendants, against whom the evidence was not admitted,
    fail to articulate how it affected their rights. Any potential prejudice
    to them of being tried jointly with the defendants against whom the
    prior-crimes evidence was admitted is addressed in connection with
    objections that certain defendants’ trials should have been severed.
    17
    formed and certain defendants’ intent. Given the care the
    district court took to limit and focus the evidentiary
    presentation, its prejudicial potential did not outweigh its
    probative value under Rule 403.
    A.
    Before trial, the government submitted a notice of its
    intent to introduce evidence that some of the defendants
    participated in uncharged hostage takings. The district court
    admitted the evidence as relevant to issues other than the
    defendants’ bad character—namely “the background of the
    conspiracy and how the relationships between the participants
    developed, as well as defendants’ motive, intent, knowledge,
    preparation, and plan.” United States v. Straker, 
    567 F. Supp. 2d
    174, 178–79 (D.D.C. 2008). The evidence was strongly
    probative, in the district court’s view, and thus its value was
    not substantially outweighed by the “fairly low” danger of
    unfair prejudice. 
    Id. at 179.
    The district court restricted the government’s presentation
    of the “other crimes” evidence in order to avoid “unnecessary
    presentation of cumulative evidence and to minimize the
    danger of unfair prejudice.” 
    Id. The district
    court precluded
    the government from introducing any evidence concerning the
    Gopaul hostage taking—an offense in which the hostage takers
    apparently killed the victim after they received an
    unsatisfactory ransom offer—because that evidence presented
    “the most likely case for some degree of unfair prejudice.” 
    Id. Additionally, the
    court permitted the government to introduce
    only three of the four other uncharged hostage takings the
    government identified, id.; see also J.A. 961–62, and limited
    the testimony on those to three hours each. J.A. 3171–72.
    The government accordingly introduced at trial evidence
    that defendants Pierre and De Four participated in three of the
    18
    uncharged hostage takings, and that defendant Clarke
    participated in two of them. The evidence came in through
    the testimony of the four cooperating co-conspirators and six
    additional witnesses, including the victim of one hostage
    taking and Trinidadian law enforcement officials involved in
    investigating the other hostage takings. The district court
    gave limiting instructions to the jury periodically during the
    trial, informing it that the evidence of other hostage takings
    was admissible only against the specific defendants the jury
    found were involved in them and explaining the purposes for
    which the evidence could, and could not, be considered. See
    
    Clarke, 767 F. Supp. 2d at 27
    –28.
    B.
    On appeal, defendants argue that the district court’s
    admission of evidence of the three uncharged hostage takings
    violated Rule 404(b) because it was not admitted for any of the
    valid purposes enumerated in that Rule, but impermissibly to
    show their bad characters and propensity to commit the
    charged crimes.      The evidence’s probative value was
    substantially outweighed by its unfair prejudicial effect, they
    assert, and was presented in a confusing and prejudicial
    manner, so should have been excluded under Rule 403.
    The evidentiary limitation in Rule 404(b) implements the
    fundamental tenet of our criminal justice system that
    defendants may be convicted only for violating the law, not for
    being bad people. United States v. Sutton, 
    801 F.2d 1346
    ,
    1360 (D.C. Cir. 1986). The Rule prohibits the admission of
    evidence of a crime, wrong, or other bad act “when offered for
    the purpose of proving that a defendant acted in conformity
    with his character, but allows admission so long as the
    evidence is offered for any other relevant purpose.” United
    States v. Lawson, 
    410 F.3d 735
    , 741 (D.C. Cir. 2005); United
    19
    States v. Bowie, 
    232 F.3d 923
    , 930 (D.C. Cir. 2000); see also
    Fed. R. Evid. 404(b)(1). Relevant, non-propensity purposes
    include “proving motive, opportunity, intent, preparation, plan,
    knowledge, identity, absence of mistake, or lack of accident.”
    Fed. R. Evid. 404(b)(2).
    Even if a court determines that the prosecution’s
    other-crimes evidence is relevant to an issue apart from
    propensity, the evidence may nonetheless be excluded under
    Rule 403 if its “probative value is substantially outweighed by
    a danger of . . . unfair prejudice, confusing the issues,
    misleading the jury, undue delay, wasting time, or needlessly
    presenting cumulative evidence.” Fed. R. Evid. 403; 
    Bowie, 232 F.3d at 930
    . Even if it is concededly relevant, unduly
    prejudicial evidence may be excluded to prevent jurors from
    impermissibly relying on biases, dislikes, or the emotional
    impact of the evidence, for example by drawing on
    assumptions about a defendant’s bad character, rather than
    proof of the criminal conduct charged.              The Rule’s
    requirement that the danger of unfair prejudice substantially
    outweigh probative value calls on us, in close cases, to lean
    towards admitting evidence. United States v. Douglas, 
    482 F.3d 591
    , 600 (D.C. Cir. 2007); United States v. Manner, 
    887 F.2d 317
    , 322 (D.C. Cir. 1989).
    We review a district court’s admission of other-crimes
    evidence for abuse of discretion, United States v. Mathis, 
    216 F.3d 18
    , 25–26 (D.C. Cir. 2000), according “substantial
    deference” to the district court, 
    Lawson, 410 F.3d at 741
    ; see
    also United States v. Long, 
    328 F.3d 655
    , 660 (D.C. Cir. 2003).
    We review Rule 403 balancing decisions “only for grave
    20
    abuse.” 
    Douglas, 482 F.3d at 596
    (internal quotation marks
    omitted). 2
    1.
    The district court did not abuse its discretion in concluding
    that evidence of particular defendants’ involvement in
    uncharged hostage takings was relevant to both how those
    defendants started to work together as kidnappers, and their
    motive and intent to kidnap wealthy civilians to extort ransom
    money. “In a conspiracy prosecution, the government is
    usually allowed considerable leeway in offering evidence of
    other offenses” to, for example “inform the jury of the
    background of the conspiracy charged” or “help explain to the
    jury how the illegal relationship between the participants in the
    crime developed.” 
    Mathis, 216 F.3d at 26
    (internal quotation
    marks omitted); see 
    Manner, 887 F.2d at 322
    . Evidence that
    defendants jointly engaged in other criminal activity can be
    relevant to shed light on how the “relationship of mutual trust”
    developed between those individuals. See United States v.
    Escobar-de Jesús, 
    187 F.3d 148
    , 169 (1st Cir. 1999)
    (collecting cases).        The district court admitted the
    other-crimes evidence as tending to show that a criminal
    relationship formed between Pierre, De Four, Clarke, and the
    cooperating co-conspirators during other, uncharged hostage
    takings. That prior criminal relationship helped to explain
    how Pierre, De Four, and Clarke knew they could rely on one
    2
    “[T]he principles governing what is commonly referred to as
    other crimes evidence are the same whether the conduct occurs
    before or after the offense charged.” United States v. Latney, 
    108 F.3d 1446
    , 1450 (D.C. Cir. 1997) (internal quotation marks omitted).
    It makes no difference, therefore, that two of the uncharged hostage
    takings occurred before the Maharaj hostage taking and that one
    occurred after.
    21
    another during the Maharaj hostage taking. The district court
    did not impermissibly admit evidence of the uncharged hostage
    takings merely to allow the government to provide the jury
    with general background information that completed the
    prosecutor’s narrative, see 
    Bowie, 232 F.3d at 929
    , but rather
    admitted it as tending to establish how the defendants in this
    case formed the Maharaj hostage-taking conspiracy.
    The uncharged hostage takings were also relevant to
    establish the defendants’ state of mind. Information showing
    that Pierre, De Four, and Clarke had worked closely before on
    very similar hostage takings helped to dispel any doubt as to
    whether they knowingly and intentionally joined together to
    carry out these crimes in order to extract significant ransoms.
    Intent, knowledge, and motive are “well-established
    non-propensity purposes for admitting evidence of prior
    crimes or acts.” 
    Bowie, 232 F.3d at 930
    ; see also Fed. R.
    Evid. 404(b)(2). As we have previously observed, evidence
    relevant to intent and motive “is particularly probative where
    the government has alleged conspiracy.” 
    Mathis, 216 F.3d at 26
    (internal quotation marks omitted). To prove conspiracy to
    commit hostage taking, the government was required to
    establish that the conspiracy was knowingly formed and that
    defendants willfully participated in the plan to commit it with
    the intent to further some purpose of the conspiracy. See
    United States v. Yunis, 
    924 F.2d 1086
    , 1096 (D.C. Cir. 1991).
    Potential juror doubt about whether any of these three
    defendants was somehow mistakenly swept up into activities
    he did not know were part of a criminal conspiracy is
    powerfully undermined by the evidence of similar criminal
    teamwork with some of the same people, both before and after
    the Maharaj hostage taking. Any questions about motive also
    tended to be put to rest by evidence that the conspirators
    successfully obtained ransoms in the other, uncharged hostage
    takings. The district court thus permissibly held that the
    22
    other-crimes evidence was relevant for non-propensity
    purposes. 3
    2.
    That conclusion does not end our inquiry. Even where
    other-crimes evidence is relevant for a non-propensity purpose,
    it nevertheless is inadmissible under Rule 403 if the potential
    for prejudice from introducing the evidence outweighs its
    probative value. See 
    Douglas, 482 F.3d at 600
    . We see no
    reason, however, to disturb the district court’s carefully
    reasoned Rule 403 determination. See Straker, 
    567 F. Supp. 2d
    at 179. The district judge identified the strong probative
    value of the evidence for the purposes we have just discussed:
    to show the defendants’ willingness to trust one another and
    work together to kidnap civilians as a means to extort ransom
    3
    Defendants also assert that the district court erred by concluding
    that evidence of the uncharged hostage takings was probative of their
    modus operandi. We express no view on that question because,
    even if defendants were correct, it makes no difference here, given
    that the evidence was properly admitted for other permissible
    purposes. It is worth noting, however, that the defendants’
    argument appears to hinge on a misunderstanding of the district
    court’s opinion. Defendants point to the district court’s discussion
    of ways in which the other hostage takings were similar to the
    charged offense, and its observation that they were all close in time.
    Straker, 
    567 F. Supp. 2d
    at 178. The district court did not thereby
    hold that the evidence was admissible to show a similar modus
    operandi in both the charged and uncharged offenses. That part of
    its analysis instead related to whether the evidence of the uncharged
    hostage takings met the “threshold level of similarity” to the charged
    hostage taking, without which it could not have admitted the
    evidence as relevant to defendants’ intent, motive, and knowledge.
    See 
    id. (citing Long,
    328 F.3d at 661); see also 
    Manner, 887 F.2d at 321
    .
    23
    money. The danger of unfair prejudice was minimal because
    the other-crimes evidence added “‘no emotional or other
    pejorative emphasis not already introduced by the evidence’”
    of the crime charged in this case. 
    Id. (quoting Lawson,
    410
    F.3d at 742). Indeed, the facts of this kidnapping are
    significantly more damning because, unlike the uncharged
    other crimes the judge allowed the prosecution to establish, this
    one went awry. After defendants held their victim, an
    American citizen, hostage for seven days without necessary
    diabetes medication, he died. Several defendants then
    dismembered his body with a machete and packed the pieces in
    two large coolers in an effort to conceal their crime.
    The district court effectively barred cumulative
    evidentiary presentations and used safeguards to minimize any
    potential prejudice from the admission of the other-crimes
    evidence. In addition to limiting the number of other crimes
    about which the prosecution could introduce evidence, and
    strictly rationing the trial time allowed for those evidentiary
    presentations, Straker, 
    567 F. Supp. 2d
    at 179; see also J.A.
    961–62; J.A. 3171–72, the court paid careful attention to the
    nature of the testimony that was introduced and prevented the
    government from soliciting testimony about particularly
    prejudicial details. See J.A. 3462–66; J.A. 3686–88. The
    court excluded all evidence of two uncharged hostage takings,
    including the one that raised the greatest risk of unfair
    prejudice. As already noted, the evidence in that kidnapping
    suggested that the captors intentionally killed their hostage in
    response to an insufficient ransom offer, see Straker, 
    567 F. Supp. 2d
    at 179—a response arguably even more brutal than
    the deprivation of life-sustaining medication that led to the
    predictable demise of the victim in this case.
    Defendants further argue that the uncharged
    hostage-takings evidence was “wholly unnecessary” to the
    24
    government’s case, such that any minimal probative value was
    substantially outweighed by the prejudice it caused, in
    violation of Rule 403. Defendants find unpersuasive the
    theories discussed above, regarding the probativeness of the
    other-crimes evidence to questions of relationship, motive, and
    intent; they contend that the government had ample, less
    prejudicial ways to make the same points. Defendants
    contend that the evidence was unnecessary to show their
    relationships, given other evidence that the defendants formed
    friendships in boyhood or during military service. That
    evidence, however, does not speak to their repeated experience
    of trusting one another to carry through with felonious
    conspiracies without revealing their activities to law
    enforcement. Defendants also contend that the evidence of
    the uncharged hostage takings was unnecessary to show their
    intent or motive because they did not raise innocent-motive
    defenses. That argument ignores the government’s burden,
    regardless of the nature of the defense, to prove beyond a
    reasonable doubt that defendants knowingly and intentionally
    joined the conspiracy to kidnap Maharaj. See 
    Douglas, 482 F.3d at 597
    ; Old Chief v. United States, 
    519 U.S. 172
    , 187–88
    (1997). In sum, the district judge’s careful sorting of the
    other-crimes evidence and the limitations he placed on how
    much other-crimes evidence the prosecution could use
    successfully allowed the evidence which was most probative
    while avoiding unfair prejudice. The district court did not
    abuse its discretion by refusing to exclude the evidence of the
    uncharged hostage takings under Rule 403.
    3.
    Lastly, we turn to defendants’ argument that the
    government presented evidence of the uncharged hostage
    takings in such a “disorganized and confusing fashion” that
    they were prejudiced. Def. Br. 56 (citing United States v.
    25
    Sampol, 
    636 F.2d 621
    , 645 (D.C. Cir. 1980); United States v.
    Foskey, 
    636 F.2d 517
    , 524 n.6 (D.C. Cir. 1980)). As we
    discuss more fully, infra, in connection with the post-trial
    severance motion, the district court concluded that the jury was
    able to correlate the evidence with each defendant against
    whom it was properly introduced, and to avoid spillover
    consideration of evidence against defendants to whom it did
    not relate. See 
    Clarke, 767 F. Supp. 2d at 26
    –27. Defendants
    have failed to persuade us that the district court abused its
    discretion in so concluding. The government presented
    evidence about the other hostage takings, in part through
    testimony of cooperating co-conspirators who spoke about
    some of the uncharged offenses before describing the charged
    offense in greater detail.          Because the cooperating
    co-conspirators generally testified about the hostage takings in
    chronological order and each hostage taking involved a
    different victim, the jury was provided with clear guideposts
    with which to differentiate and compartmentalize each event.
    The district court repeatedly and carefully instructed the
    jury as to which defendants were involved in which of the other
    crimes, and cautioned the jurors to consider evidence only
    against those specific defendants, thereby protecting all of the
    defendants against any potential confusion stemming from the
    other-crimes evidence.         See 
    Long, 328 F.3d at 662
    (“[L]imiting instructions ordinarily suffice to protect the
    defendant’s interests.” (citing Spencer v. Texas, 
    385 U.S. 554
    ,
    561 (1967)). The court gave limiting instructions concerning
    the evidence of other hostage takings six times throughout the
    course of the trial: after opening statements, the first time that
    the other-crimes evidence was introduced by the government,
    at several points during the trial, and as part of the final jury
    instructions. In the various instructions, the court cautioned
    the jury that the evidence of the uncharged hostage takings was
    admissible for only limited purposes: informing the jurors of
    26
    the background of the conspiracy, helping them decide
    whether there were relationships between the co-conspirators,
    and aiding their determinations as to whether the defendants
    had motive, intent, knowledge, or a plan to commit the
    Maharaj hostage taking. The court also made clear that the
    other-crimes evidence was admissible only against the
    particular defendants the jurors found were involved in those
    other crimes, alternating between specifically naming the
    defendants involved in the other hostage takings and generally
    referring to those defendants. Juries are presumed to follow
    instructions that caution them to draw only permissible
    inferences from Rule 404(b) evidence. See United States v.
    Brown, 
    597 F.3d 399
    , 405–06 (D.C. Cir. 2010). The district
    court’s detailed instructions guided the jurors to
    compartmentalize and properly consider the evidence of
    uncharged hostage takings.
    Defendants have identified a handful of examples where
    the district judge expressed some confusion regarding the
    presentation of evidence of the uncharged hostage takings. In
    several instances, the district court identified potential
    confusion only to reinforce to the prosecution the importance
    of making clear to the jury which hostage taking the witness
    was discussing. Several references to confusion were made
    during bench conferences out of the jury’s hearing. The
    record portions on which defendants rely demonstrate not that
    the evidence was presented in a misleading fashion, but rather
    that the district court took great care to reduce the potential for
    confusion. The isolated examples of confusion identified by
    defendants do not show that the other-crimes evidence was so
    unclear or misleading that the jury was unable to follow the
    district court’s limiting instructions.
    Defendants claim the government’s closing argument
    intensified confusion about the other-crimes evidence by
    27
    stating that the same “crew” or “organization” carried out all of
    the hostage takings, and that Pierre was the “godfather” of the
    crew. Contrary to defendants’ characterization, however, no
    prosecutor argued that Pierre’s crew committed all of the
    hostage takings. The government’s closing did refer to the
    “crew” or group of individuals involved in the Maharaj hostage
    taking. The government also argued that Pierre was involved
    in all of the hostage takings, and indeed was in charge during
    each of those hostage takings. The evidence presented at trial
    supported each of those points. What the government did not
    assert was that Pierre led the same crew in each instance, and
    the trial evidence and judge’s instructions protected against
    any such conclusion. 4
    For all of these reasons, we conclude that the district court
    acted within its sound discretion in admitting at trial evidence
    about three uncharged hostage takings.
    4
    For similar reasons, the argument that the proof at trial represented
    a material variance from the indictment, even if preserved below, is
    meritless. Even if we were to assume that the trial evidence in this
    case materially varied from the indictment (and the defendants give
    us little reason to think that is the case), the defendants nonetheless
    cannot show the requisite substantial prejudice. Given the focused
    and limited nature of what was actually argued or established
    regarding other incidents involving groups led by Pierre and the
    district court judge’s careful limiting instructions, it simply was not
    the case that the jury here was “substantially likely” to consider
    against the defendants evidence of a RICO conspiracy not charged in

    IV.
    Confrontation Clause Challenge to Use of
    Codefendants’ Statements
    Defendants next contend that the district court violated
    their Sixth Amendment rights to confront the witnesses against
    them when it admitted into evidence redacted confessions
    made by their fellow defendants that inculpated them in the
    Maharaj hostage taking. 5 We conclude that the admission of
    the redacted confessions did not violate the Confrontation
    Clause, with the exception of the violation acknowledged by
    the government, which, in view of the independent and
    overwhelming evidence in support of the conviction, was
    harmless.
    A.
    The conspiracy was alleged to have involved at least a
    dozen men, seven of whom were tried jointly in this case.
    After they were arrested, five of the defendants gave
    statements to law enforcement officials confessing their own
    5
    In a footnote, all defendants, save Straker, seek to join this
    argument. Def. Br. 60 n.27. As discussed supra note 1, adoption
    by reference is permitted only to the extent we can readily apply the
    proponent’s arguments to the adopter’s case. Some of the
    defendants’ Confrontation Clause arguments are purely legal and
    can readily be adopted. Others are fact-specific, rendering adoption
    by reference inappropriate. Clarke, Demerieux, and Nixon have
    made fact-specific arguments that explain how they believe their
    constitutional rights were violated by the introduction of their
    codefendants’ out-of-court statements. We therefore limit our
    consideration of defendants’ fact-specific arguments to those
    particular defendants.

    participation in the Maharaj hostage taking. Before trial, the
    government filed a notice of its intent to introduce at trial the
    out-of-court statements made by codefendants Clarke,
    Demerieux, and Sealey. 6 Defendants objected on Sixth
    Amendment grounds to the admission of the statements and
    also moved to sever their trials. The district court concluded
    that separate trials would not be necessary because each
    statement could be adequately redacted and other safeguards
    used in order fully to protect the non-declarant defendants’
    Sixth Amendment confrontation rights. The district court
    ordered the government to redact the statements to remove
    references identifying defendants other than the declarant
    whenever possible. When full redaction was not possible, the
    court instructed the government to replace a particular name
    with a neutral term, sufficient to “avoid creating an inevitable
    association with a particular defendant or defendants when the
    statement is viewed together with other evidence.” J.A. 2079.
    The court also provided the government with a detailed set of
    guidelines, recounted below, specifying the types of neutral
    terms that would be acceptable and those that would not, along
    with other safeguards of defendants’ confrontation rights.
    6
    The government introduced ten confessions made by five
    different defendants. Two of those defendants, De Four and
    Straker, testified at trial. Defendants cannot raise Confrontation
    Clause challenges to the admission of those pretrial statements, as
    they had the opportunity to subject De Four and Straker to
    cross-examination. See, e.g., Crawford v. Washington, 
    541 U.S. 36
    ,
    68–69 (2004). Furthermore, none of the defendants identifies any
    statements or redactions in those confessions that implicated him.
    On appeal, therefore, we focus on defendants’ arguments concerning
    the introduction of Clarke, Demerieux, and Sealey’s confessions.
    30
    B.
    Defendants contend that the use of neutral-pronoun
    redactions was inadequate, and that the Confrontation Clause
    instead demands full redaction of codefendants’ confessions to
    eliminate any reference to fellow defendants that jurors might
    infer to be references to non-declarant defendants. See
    Richardson v. Marsh, 
    481 U.S. 200
    (1987). Alternatively,
    redactions used here were inadequate because, defendants
    claim, when a redacted confession was considered alongside
    the other evidence presented at trial, it inevitably pointed an
    inculpatory finger at a particular defendant, contrary to Gray v.
    Maryland, 
    523 U.S. 185
    (1998).
    The government responds that the Confrontation Clause
    does not require removal of all references to defendants,
    anonymized as the remaining references were, and that full
    redaction would have substantially diminished the value of the
    statements against the declarants themselves. Full redactions
    were not always practicable in this case, the government
    contends, because the declarants were charged with
    conspiracy. Eliminating from their statements all references
    to their co-conspirators jointly on trial would have “deprived
    the government of powerful conspiracy evidence” that it was
    entitled to use. Gov’t Br. 94.
    We review de novo the district court’s legal conclusions
    under the Confrontation Clause, United States v. Wilson, 
    605 F.3d 985
    , 1003 (D.C. Cir. 2010), and subject to harmless-error
    analysis any legal errors it may have made, United States v.
    Moore, 
    651 F.3d 30
    , 69 (D.C. Cir. 2011).
    1.
    The Confrontation Clause of the Sixth Amendment
    provides a criminal defendant with the right “to be confronted
    31
    with the witnesses against him,” including the right to
    cross-examine those witnesses. U.S. Const. Amend. VI; see
    Pointer v. Texas, 
    380 U.S. 400
    , 404 (1965). Use of a
    defendant’s own confession against him raises no
    confrontation issues. The admission of a codefendant’s
    confession implicating another defendant, however, poses
    special risks to the defendant’s confrontation rights. When
    the declarant expressly implicates another defendant yet
    renders himself unavailable for cross examination by asserting
    his Fifth Amendment right not to testify, use of his statement
    violates the defendant’s right to confront his accuser. See
    Bruton v. United States, 
    391 U.S. 123
    , 137 (1968). But at
    least when (1) the jury is instructed to consider the confession
    against the declarant only, and (2) redactions are made such
    that the statement, together with other trial evidence, neither
    expressly identifies defendants nor creates any inevitable
    association between them and the criminal activity the
    statement describes, there is no Sixth Amendment violation.
    See Richardson, 
    481 U.S. 200
    , 211; United States v.
    Washington, 
    952 F.2d 1402
    , 1406–07 (D.C. Cir. 1991).
    The framework for analyzing limitations on use of
    codefendants’ statements is established by a trilogy of
    Supreme Court Confrontation Clause cases: Bruton, 
    391 U.S. 123
    , Richardson, 
    481 U.S. 200
    , and Gray, 
    523 U.S. 185
    . The
    district judge who presided over defendants’ joint trial in
    Bruton admitted into evidence a non-testifying codefendant’s
    confession incriminating the 
    defendant. 391 U.S. at 124
    .
    The Supreme Court found a Sixth Amendment violation,
    overruling a prior decision sustaining a conviction in similar
    circumstances, because that precedent placed unwarranted
    confidence in the efficacy of limiting jury instructions. 
    Id. at 126
    (overruling Delli Paoli v. United States, 
    352 U.S. 232
    (1957)). The Bruton Court acknowledged that it is unrealistic
    to expect a jury to rely on a statement when deciding the guilt
    32
    of the confessing codefendant, yet ignore the same statement
    when considering the guilt of the defendant it mentions as an
    accomplice. 
    Id. at 131,
    135–36. Justice Stewart summed up
    the inadequacy of limiting jury instructions in such settings:
    “A basic premise of the Confrontation Clause . . . is that certain
    kinds of hearsay are at once so damaging, so suspect, and yet
    so difficult to discount, that jurors cannot be trusted to give
    such evidence the minimal weight it logically deserves,
    whatever instructions the trial judge might give.” 
    Id. at 138
    (Stewart, J., concurring) (internal citation omitted).
    The Court has since established that non-testifying
    codefendants’ statements may be introduced at joint trials if
    sufficient redactions can be made and adequate jury
    instructions given to protect the rights of codefendants. In
    Richardson, the codefendant’s confession was fully redacted to
    eliminate all references to the 
    defendant. 481 U.S. at 203
    .
    The confession only implicated the defendant when it was
    considered alongside her own testimony, placing her at the
    scene of a critical conversation the confession described. 
    Id. at 205–06,
    208. The Court found no Confrontation Clause
    violation in Richardson because the statement was “not
    incriminating on its face,” but became potentially
    incriminating “only when linked with evidence introduced
    later at trial.” 
    Id. at 208.
    Even then, the inference was not
    obvious, such that the limiting jury instructions sufficed to
    guard against the remaining risk of “inferential incrimination.”
    
    Id. In contrast
    to the “[s]pecific” and “vivid” incriminating
    statement at issue in Bruton that created an “overwhelming
    probability” that jurors would fail to heed limiting instructions,
    
    id. at 208–09,
    the redacted statement in Richardson made any
    incriminating implication sufficiently indirect that jury
    instructions could be counted on to “dissuad[e] the jury from
    entering onto the path of inference in the first place.” 
    Id. at 208.
                                   33
    The adequacy under the Confrontation Clause of redacting
    a non-testifying codefendant’s statement depends on how
    effectively the redaction eliminates the statement’s accusatory
    implication. Evaluations of such effectiveness are necessarily
    contextual. In Gray v. Maryland, the prosecution only
    crudely redacted a codefendant’s statement by whiting out the
    names of Gray and the other alleged perpetrator (who had since
    died), leaving blank spaces separated by 
    commas. 523 U.S. at 188
    . The police witness reading to the jury from the
    confession said “deleted” or “deletion” each time he
    encountered a blank. 
    Id. Such redaction
    did little, if
    anything, to cure the prejudice to the defendant. The Court
    determined that the “blank space in an obviously redacted
    confession . . . points directly to the defendant, and it accuses
    the defendant in a manner similar to [the non-testifying
    codefendant’s] use of Bruton’s name or to a testifying
    codefendant’s accusatory finger,” and thus requires the same
    result as in Bruton. 
    Id. at 194.
    Even though the redacted
    confession in Gray never named the defendant on trial, it called
    the jurors’ attention to his codefendants’ inculpation of him
    with sufficient clarity that no limiting jury instruction could
    suffice. The difference in outcomes in Gray and Richardson
    depended “in significant part upon the kind of, not the simple
    fact of, inference.” 
    Id. at 196.
    Gray “involve[d] inferences
    that a jury ordinarily could make immediately, even were the
    confession the very first item introduced at trial,” 
    id., whereas the
    inferences in Richardson were attenuated.
    The Supreme Court has not yet determined the
    permissibility under the Sixth Amendment of the type of
    redaction at issue here, which eliminated names and
    identifying references to specific defendants (without signaling
    that changes had been made), but left intact some of the
    statements’ descriptions of people doing things to advance the
    crimes with which the defendants were charged. Indeed, the
    34
    Court in Richardson was careful to note that it “express[ed] no
    opinion on the admissibility of a confession in which the
    defendant’s name has been replaced with a symbol or neutral
    
    pronoun.” 481 U.S. at 211
    n.5. The redactions in this case
    fall somewhere between the full redaction that Richardson
    sustained, and the obviously inculpatory blank spaces and
    deletions that Gray held to be insufficient. The Court has,
    however, hinted how redactions might effectively be used in
    cases involving several perpetrators: In disapproving the
    obvious redactions in Gray, the Court noted that the
    incriminating references to “Me, deleted, deleted, and a few
    other guys” could have been changed to “Me and a few other
    
    guys.” 523 U.S. at 196
    .
    Our circuit has infrequently considered the kind of
    neutral-pronoun redactions approved by the district court in
    this case. Evaluation of the potential inculpatory implications
    of a non-testifying codefendant’s redacted confession is
    necessarily contextual.      We have held that putatively
    anonymized references to a defendant in a codefendant’s
    statement violated Bruton where the statement still called
    attention to the declarant’s accusation against the defendant.
    See Serio v. United States, 
    401 F.2d 989
    , 990 (D.C. Cir. 1968)
    (per curiam). Elsewhere, we found neutral-pronoun redaction
    constitutionally adequate where, describing a transaction in
    which several people were involved, a statement was redacted
    to replace the defendant’s name with neutral pronouns that, in
    context, did not inevitably refer to the defendant. See
    
    Washington, 952 F.2d at 1406
    ; see also United States v.
    Applewhite, 
    72 F.3d 140
    , 145 (D.C. Cir. 1995).
    Serio, a case we decided immediately after Bruton and
    that, like Bruton, involved just two alleged perpetrators, held
    that the admission of a codefendant’s confession in which the
    defendant’s name was replaced with the phrase “another man”
    35
    violated the defendant’s confrontation right because of the
    “well-nigh inevitable association of [the defendant] as the
    ‘other man’ referred to in [his codefendant’s] 
    confession.” 401 F.2d at 989
    –90. After Richardson but before Gray,
    however, we sustained in Washington the use of nonobvious,
    neutral-pronoun redaction together with limiting jury
    instructions in circumstances in which the redacted statement
    could have referred to several individuals other than the
    
    defendant. 952 F.2d at 1406
    . In that context, the neutrally
    redacted statement created no “inevitable association” between
    the defendant and the inculpatory conduct the statement
    describes. 
    Id. (citing Serio,
    401 F.2d at 990). Washington
    questioned whether Serio’s “inevitable association” standard
    might be more protective of defendants’ rights than the Sixth
    Amendment requires, but left that matter undecided because
    that challenge failed even under Serio. 
    Id. Here, too,
    we see
    no need to consider whether Serio is overprotective, because
    that standard was satisfied here.
    In sum, at least when “all references to the defendant in a
    codefendant’s statement are replaced with indefinite pronouns
    or other general terms, the Confrontation Clause is not violated
    by the redacted statement’s admission if, when viewed
    together with other evidence, the statement does not create an
    inevitable association with the defendant, and a proper limiting
    instruction is given.” 
    Washington, 952 F.2d at 1406
    –07. In
    such circumstances, provided that the jury is instructed not to
    consider the codefendant’s statements as evidence against
    anyone but the declarant himself, as happened here, Bruton is
    not violated. 7
    7
    Our approval of the use of neutral pronouns and other general
    terms accords with that of other circuits. See, e.g., United States v.
    Vasilakos, 
    508 F.3d 401
    , 407–08 (6th Cir. 2007) (collecting federal
    36
    2.
    In their Bruton challenge, defendants first argue that the
    district court erred by failing to require the government to
    redact fully the codefendants’ confessions to eliminate even
    anonymized references to other perpetrators. They assert that
    neutral-pronoun redactions do not adequately protect
    defendants’ confrontation rights because they leave in place
    inevitable associations with the defendants. In their view,
    only full redaction would suffice. Defendants further contend
    that, even if the Sixth Amendment permits jurors to hear
    anonymized references to defendants’ criminal activity, the
    redactions here were inadequate. The sheer number of
    redactions, combined with grammatical errors in redaction,
    they claim made it clear to the jury in this case that the
    confessions were altered, and thus impermissibly pointed the
    finger at them.
    We do not accept the defendants’ claim that anything short
    of full redaction violates their confrontation rights. The
    prosecution made full redactions in several places where it
    could do so without creating unacceptable confusion or
    distortion. But, as Washington makes clear, the Confrontation
    Clause does not always mandate full redactions. Carefully
    made neutral-pronoun redactions can avoid the defect of
    elisions so crude that they “obviously refer directly to
    someone, often obviously the defendant.” 
    Gray, 523 U.S. at 196
    .     The critical question is whether the redactions
    adequately conceal the fact that the declarant identified the
    defendant in particular—a fact that, if known, would make it
    appellate decisions); see also United States v. Ramos-Cardenas, 
    524 F.3d 600
    , 608–09 (5th Cir. 2008); United States v. Vega Molina, 
    407 F.3d 511
    , 519–21 (1st Cir. 2005); United States v. Sutton, 
    337 F.3d 792
    , 799–801 (7th Cir. 2003).
    37
    unlikely that a jury would be able to follow a limiting
    instruction. See 
    id. Viewing the
    text of the statements as a whole and in the
    context of the facts and evidence in the case, we disagree that
    the redactions made it obvious that the statements referred to
    specific defendants. The neutral-pronoun redactions here
    were a far cry from those in Gray, where the method of
    redaction only strengthened the inference that the
    Confrontation Clause required be attenuated. Despite the
    need for frequent redactions in this case, each resulting
    statement resembled a confession that a defendant might have
    made if he were trying to avoid identifying his co-conspirators.
    A defendant endeavoring not to point the finger at his
    confederates would need repeatedly to rely on the kinds of
    vague references, such as “them” and “the other guy,” that
    these redacted statements use. In fact, even before his
    statement was redacted, Clarke referred to his co-conspirators
    as “fella” or “fellas” six times in two transcript pages. The
    government noted such speech patterns, making efforts when
    crafting the redactions to mimic the speaker’s own language
    patterns and word choices to make the redactions
    inconspicuous.       The single, ungrammatical redaction
    identified by defendants—in which Clarke’s statement
    erroneously omitted a definite article before referring to “other
    guy”—did not make it obvious that the statement had been
    redacted: the awkward language could just as plausibly have
    resulted from a misstatement (by either the declarant or
    testifying officer) or typographical error in transcribing the
    confession.
    Defendants also contend that the confessions, redacted as
    they were, violated their confrontation rights because, when
    considered alongside the other evidence presented at trial, the
    confessions created inevitable inculpatory associations with
    38
    particular defendants. When a confession is redacted with
    neutral pronouns, a jury, after hearing all of the evidence
    presented in the case, may still very well be able to draw
    inferences that the “other guy” mentioned in the confession
    was actually one of the defendants. Bruton is not violated,
    however, whenever a jury may be able to draw such an
    inference. Instead, it is violated when the inferences are so
    strong and obvious that a jury cannot be expected to follow
    limiting instructions. See 
    Gray, 523 U.S. at 196
    .
    The evidence identified more than a dozen different men
    involved in the crimes charged in this case, making it unlikely
    that the jury would readily link a statement’s mention of a
    “person” or “guy” to a specific defendant. See 
    Washington, 952 F.2d at 1406
    ; see also United States v. Vasilakos, 
    508 F.3d 401
    , 408 (6th Cir. 2007); United States v. Vega Molina, 
    407 F.3d 511
    , 520 (1st Cir. 2005); United States v. Sutton, 
    337 F.3d 792
    , 799 (7th Cir. 2003). There were seven defendants
    standing trial and four cooperating co-conspirators who
    testified against them, plus several unindicted individuals
    whom the cooperators implicated in the hostage taking, not to
    mention the participants in the other kidnappings admitted into
    evidence, whom the jury could not be sure played no role in
    this case. To further attenuate any inculpatory inference,
    Clarke’s redacted statements repeatedly referred to someone
    named “Igloo,” an apparently fictitious character made up by
    Clarke, to whom he ascribed the actions of several different
    members of the conspiracy. Because of the number of
    identified participants, the statements, redacted as they were
    and accompanied by limiting instructions, supported no
    “inevitable association” between the persons described and
    any of the alleged co-conspirators standing trial, let alone a
    particular defendant.
    39
    Defendants contend that the redacted statements
    impermissibly identified them because of the recognizable
    roles they played in the crime. Clarke and Demerieux acted as
    guards at the camp, and Sealey and Nixon were the gunmen
    who abducted Maharaj from the bar. Each of Clarke and
    Demerieux’s redacted statements refers to the “other guy” or
    “another fella” at the camp with the victim. Sealey’s redacted
    statement refers to himself and “the other man” abducting the
    victim. Defendants argue that, despite those redactions, the
    jury would inevitably associate each of them with a particular,
    unnamed “guy” or “fella” based on other trial testimony:
    Cooperators Jason Percival and Russel Joseph both stated that
    Clarke and Demerieux were at the campsite for the vast
    majority of the time between when Maharaj was abducted and
    when he died, and, in testifying that they were present when the
    victim was abducted, they identified Sealey and Nixon as the
    men who entered the bar and abducted Maharaj.
    The discernible roles some defendants played were not so
    clear and exclusive as defendants contend, however, but often
    overlapped with the activities of other defendants and
    co-conspirators. For example, the evidence showed that,
    when Clarke and Demerieux were guarding the hostage at the
    camp, there were often other men, whether defendants or
    cooperating co-conspirators, present at the campsite. In light
    of the multiple comings and goings at the campsite, any
    reference to someone else there did not obviously refer to
    Clarke or Demerieux. 8 Similarly, although the testimony
    showed that Sealey and Nixon were the two gunmen who
    8
    Clarke and Demerieux also argue that because their statements
    were interlocking and reinforced one another, it furthered the
    inevitable association. Given our conclusion the redactions
    obscured the references to each man in the other’s statement, we
    disagree that the statements were interlocking.
    40
    abducted Maharaj from the bar, it also showed that many other
    people were at the scene of the abduction or involved in the
    getaway.     Accordingly, even in light of the evidence
    introduced at trial concerning each defendant’s role in the
    hostage taking, anonymized references to the “other guy” or
    “another fella” in the confessions avoided creating an
    inevitable association between a confession and any particular
    complaining defendant.
    Inevitable associations were not created, in large part,
    because the district court established guidelines for redaction,
    and closely supervised the redaction process in order to ensure
    that the admission of the confessions at trial did not violate
    Bruton and its progeny:
    First, the trial judge required full redactions where
    feasible without distorting the statement’s meaning.
    See 
    Richardson, 481 U.S. at 211
    .
    Second, when it was impossible to redact fully a
    portion of a confession, the district court directed
    the government to use only non-obvious, partial
    redactions, replacing the defendants’ proper names
    or nicknames with a variety of neutral pronouns to
    make the resultant statements appear natural and
    match the defendants’ own speech.
    Third, the court required that the statements be
    scrubbed of any other designations or identifiers
    based on a defendant’s physical characteristics or
    role in the hostage taking (such as driver or guard).
    See Harrington v. California, 
    395 U.S. 250
    , 253
    (1969); United States v. Nash, 
    482 F.3d 1209
    , 1218
    (10th Cir. 2007); United States v. Hoover, 
    246 F.3d 1054
    , 1059 (7th Cir. 2001).
    41
    Fourth, the court directed that redactions avoid
    referring to specific numbers of persons, in order
    further to weaken the jury’s ability to correlate the
    statements’ references to unnamed individuals with
    members of otherwise-identified pairs or clusters of
    defendants.
    Fifth, the court reviewed drafts of the prosecution’s
    redacted statements and required additional
    changes to conform them to the court’s Bruton
    guidelines.     That safeguard helped to avoid
    clumsiness in redactions that could have been
    inculpatory.
    Sixth, by only allowing prosecution witnesses to
    use the statements to aid in their testimony without
    admitting the documents themselves into evidence,
    the court ensured that the jury did not see written
    (and perhaps discernibly altered) copies of the
    redacted confessions.
    Finally, and perhaps most importantly, the district
    court recognized that redactions would be effective
    to protect defendants’ confrontation rights because
    of the large number of actors involved in the
    alleged crime. As the court observed, the greater
    the number of alleged perpetrators involved in the
    charged offense, the more indirect the inference
    that the jury could draw from the redacted
    statements.
    Given the context of this case and the care the district court
    took regarding use of codefendants’ redacted statements, any
    inferences created by the statements were attenuated.
    Defendants do not contend, nor do we believe based on our
    review of the record, that a jury could from a statement alone
    42
    immediately make a connection between a specific defendant
    and one of the “guys,” “fellas,” or other people the statement
    mentions. When considered along with the other evidence
    presented at trial and with appropriate limiting instructions, the
    redacted confessions introduced here created no inevitable
    association between the persons the declarants described and
    particular defendants. 9
    For all of these reasons, we conclude that the redacted
    statements admitted into evidence at defendants’ trial did not
    violate Bruton.
    9
    Defendants also argue that the Supreme Court’s decision in
    Crawford, should increase the skepticism with which we review
    Bruton claims. See 
    541 U.S. 36
    . Crawford announced a general
    rule of inadmissibility of out-of-court statements by witnesses who
    are unavailable and so not subject to cross-examination. The Court
    there dealt with statements that, unlike the statements here, were not
    otherwise admissible as codefendant confessions. The Crawford
    Court held that the admissibility against a defendant of a testimonial
    statement by a non-testifying declarant depends, not merely on the
    statement’s reliability, but on whether the defendant had a prior
    opportunity to cross-examine the declarant, because the
    Confrontation Clause establishes “that reliability be assessed in a
    particular manner: by testing in the crucible of cross-examination.”
    
    Id. at 6
    1. Crawford applies to statements admitted against a
    defendant; a statement that has been effectively Bruton-ized,
    however, is one that has been redacted so that it can, with appropriate
    limiting jury instructions, be deployed only against the declarant and
    not against the objecting codefendant. See 
    Bruton, 391 U.S. at 135
    –
    36; see also 
    Richardson, 481 U.S. at 206
    . Crawford accordingly
    does not apply here, where we have determined that the statements
    are admissible under the Bruton line of cases because, properly used,
    they create no inevitable inculpating association with defendants.
    43
    3.
    Finally, we conclude that the error acknowledged by the
    government—cooperating co-conspirator Leon Nurse’s use of
    Nixon’s name while testifying about the contents of an out-of
    court confession made by Sealey—was harmless. A Bruton
    error does not necessarily require reversal, because “[i]n some
    cases the properly admitted evidence of guilt is so
    overwhelming, and the prejudicial effect of the codefendant’s
    admission is so insignificant by comparison, that it is clear
    beyond a reasonable doubt that the improper use of the
    admission was harmless error.” Schneble v. Florida, 
    405 U.S. 427
    , 430 (1972). This is such a case.
    At trial, cooperator Nurse testified that, when he and
    Sealey were incarcerated pending trial, Sealey told Nurse
    about his participation in the kidnapping. Nurse had been
    instructed for his testimony regarding Sealey’s out-of-court
    statement not to refer to any other defendant by name, but
    violated that instruction by naming Nixon when recounting
    Sealy’s confession. Nurse recounted that Sealey “said at the
    scene—at the scene of the kidnapping, [s]ir, he said that Mr.
    Nixon didn’t really want to come out of the—.” 
    Clarke, 767 F. Supp. 2d at 35
    . Recognizing the error, the district court
    immediately instructed the jury to disregard that piece of
    testimony. The government concedes that was a Bruton
    violation.
    The error was harmless beyond a reasonable doubt in view
    of its limited inculpatory value and the ample other evidence of
    Nixon’s guilt presented during the ten-week trial. Nurse used
    Nixon’s name only a single time. That single, explicit
    reference merely placed Nixon at the scene of the hostage
    taking, and did not describe his ensuing actions.             In
    comparison to that isolated utterance, the other evidence of
    44
    Nixon’s guilt was overwhelming. Cooperators Joseph and
    Percival each testified in detail about Nixon’s involvement in
    the hostage taking. Joseph testified that he drove Nixon and
    Sealey to the bar where Maharaj was abducted, that Nixon was
    armed, and that Nixon entered the bar and moments later
    returned with Sealey and the victim. After Nixon and Sealey
    forced Maharaj into the back of the getaway car, Joseph stated,
    he drove the group to a cocoa field and Nixon and Sealey led
    the victim into the field and left him there. Joseph further
    recounted that he and Nixon later returned to move Maharaj
    from the cocoa field to the campsite where Clarke and
    Demerieux guarded him. Cooperator Percival’s testimony
    closely paralleled and reinforced Joseph’s account. Both men
    also testified that, during the abduction, Nixon wore a Rasta
    hat, a detail that was corroborated by an eyewitness who did
    not participate in the abduction. Given the overwhelming
    evidence of Nixon’s guilt, Nurse’s single reference to Nixon
    was harmless beyond a reasonable doubt.
    V.
    Brady/Napue Claim
    The Constitution’s “fair trial guarantee,” United States v.
    Ruiz, 
    536 U.S. 622
    , 628 (2002), requires the prosecution to
    timely turn over any information in the government’s
    possession that is materially favorable to a criminal defendant,
    Brady v. Maryland, 
    373 U.S. 83
    (1963), and forbids the
    prosecution’s introduction of false testimony, Napue v. Illinois,
    
    360 U.S. 264
    (1959). Those are grave obligations, grounded
    in both the Fifth and Sixth Amendments to the Constitution.
    See 
    Ruiz, 536 U.S. at 628
    .
    Six of the defendants—Clarke, De Four, Nixon, Sealey,
    Demerieux, and Pierre—argue that the prosecution violated
    45
    both Brady and Napue. Specifically, those defendants object
    that Agent William Clauss’s and Sergeant Wendell Lucas’s
    testimony misleadingly implied that Clarke led them to the
    campsite where Maharaj had been held, when in fact Clarke led
    them to another location. The defendants also argue that the
    prosecutors violated both Brady and Napue when they elicited
    testimony from Percival indicating that Demerieux “hit the
    man [i.e., Maharaj] in his head with a big stone and dent his
    head,” even though available x-ray evidence revealed no such
    head injury. Lastly, the defendants argue that the prosecution
    breached its Brady obligations when it failed timely to turn
    over cooperator Russell Joseph’s initial confession, which
    identified someone other than De Four as a driver in the
    kidnapping. 10
    The prosecution’s behavior leaves much to be desired,
    falling far short of this court’s expectations. Nevertheless,
    each of the defendants’ claims ultimately fails on the merits.
    A Brady violation occurs when the prosecution (i) fails to
    disclose to the defense, whether willfully or inadvertently, (ii)
    exculpatory or impeachment evidence that is favorable to the
    accused, and (iii) the withholding of that information
    10
    Before the district court, Clarke and Demerieux moved for a new
    trial based on the campsite issue; Demerieux moved for a new trial
    based on the x-ray evidence; and De Four and Sealey moved for a
    new trial based on the Joseph confession. The other defendants did
    not raise or join those individual claims below, and so review as to
    them is for plain error only. See United States v. Johnson, 
    437 F.3d 69
    , 74 (D.C. Cir. 2006). Moreover, because the defendants’ brief
    addresses the Brady and Napue claims only as they specifically
    relate to Clarke, Demerieux, and De Four, all of the other defendants
    on each claim have failed to make even a plausible argument for
    relief, so their arguments fail at the starting gate.
    46
    prejudices the defense. See United States v. Andrews, 
    532 F.3d 900
    , 905 (D.C. Cir. 2008) (citing Strickler v. Greene, 
    527 U.S. 263
    , 281–82 (1999)); see also 
    Brady, 373 U.S. at 87
    .
    When, as here, disclosure by the prosecution happened late
    rather than not at all, the defendant must show a “reasonable
    probability that an earlier disclosure would have changed the
    trial’s result” to establish prejudice. United States v. Dean, 
    55 F.3d 640
    , 663 (D.C. Cir. 1995); see also United States v.
    (Ralph) Wilson, 
    160 F.3d 732
    , 742 (D.C. Cir. 1998) (defendant
    bears burden of proving “reasonable probability”). In this
    context, a “reasonable probability” means “a probability
    sufficient to undermine our confidence in the actual outcome
    that the jury would have acquitted.” United States v.
    Tarrantino, 
    846 F.2d 1384
    , 1417 (D.C. Cir. 1988).
    The district court denied each of the Brady claims. The
    government argues that the ruling should be reviewed only for
    clear error, reasoning that “[t]he clearly erroneous standard
    ordinarily governs review of a judge’s findings in a criminal
    case on issues other than the defendant’s guilt,” including
    review of a district court’s “conclusion that [the defendant]
    suffered no prejudice by his late access to the evidence[.]”
    United States v. Paxson, 
    861 F.2d 730
    , 737 (D.C. Cir. 1988)
    (first alteration in original). Since Paxson was decided,
    however, the Supreme Court has clarified that “there is never a
    real ‘Brady violation’ unless the nondisclosure was so serious
    that there is a reasonable probability that the suppressed
    evidence would have produced a different verdict.” 
    Strickler, 527 U.S. at 281
    . That prejudice element requires an inquiry
    into “material[ity],” 
    Andrews, 532 F.3d at 905
    , and
    materiality under Brady is a “question of law,” subject to de
    novo review, United States v. Oruche, 
    484 F.3d 590
    , 595 (D.C.
    Cir. 2007). Accordingly, our review is de novo.
    47
    A Napue violation occurs when the government
    introduces false or misleading testimony or allows it to go
    uncorrected, see Giglio v. United States, 
    405 U.S. 150
    , 153
    (1972), even though the government knew or should have
    known that the testimony was false, see, e.g., United States v.
    Agurs, 
    427 U.S. 97
    , 103 (1976). If a defendant makes that
    showing, a new trial is required if there is “any reasonable
    likelihood that the false testimony could have affected the
    judgment of the jury[.]” United States v. Gale, 
    314 F.3d 1
    , 4
    (D.C. Cir. 2003) (quoting 
    Agurs, 427 U.S. at 103
    ).
    Because none of the Napue violations asserted on appeal
    was raised below, we review for plain error, reversing only if
    we perceive that “(1) there is error (2) that is plain and (3) that
    affects substantial rights, and (4) . . . the error seriously affects
    the fairness, integrity, or public reputation of judicial
    proceedings.” 
    Johnson, 437 F.3d at 74
    (citing United States v.
    Olano, 
    507 U.S. 725
    , 732 (1993)).
    A.
    At trial, both Agent Clauss’s and Sergeant Lucas’s
    testimony misleadingly indicated that Clarke led them to the
    campsite where Maharaj was held. But, in fact, Maharaj was
    never held at that campsite, and the government knew the
    testimony was misleading at the time it was given. The
    government nevertheless chose not to reveal that to the defense
    until the overnight recess after the defense cross-examination
    of Agent Clauss, when it faxed a diagram of the campsite with
    a cover memo stating it was “believed to be Clauss diagram
    from false campsite.” J.A. 3936–38.           The prosecution
    admitted that “[w]e knew, the government knew that this was
    not going to be the right campsite.” J.A. 3945.
    48
    The district court found both that “the government knew”
    all along that the testimony was about a false campsite, and that
    the testimony misled the court (“I know I didn’t know it”), and
    “confused” the jury. J.A. 3964–65. The district court
    nevertheless denied the motion for a new trial because,
    “notwithstanding the government’s failure to disclose the
    evidence earlier, Clarke was able to incorporate it into his
    defense.” 
    Clarke, 767 F. Supp. 2d at 53
    .
    The government’s use of knowingly misleading testimony
    that confuses the court, jury, and defense alike, compounded
    by its greatly delayed release of information revealing the
    deceptive content, is deeply disappointing and troubling
    behavior, unbefitting those who litigate in the name of the
    United States. See, e.g., United States v. Ash, 
    413 U.S. 300
    ,
    319 (1973) (“The primary safeguard against abuses of [the
    prosecutorial process] is the ethical responsibility of the
    prosecutor, who, as so often has been said, may ‘strike hard
    blows’ but not ‘foul ones.’”) (quoting Berger v. United States,
    
    295 U.S. 78
    , 88 (1935)).
    But prosecutorial misbehavior alone does not a Brady
    violation make.      A reasonable possibility of concrete
    prejudice from the false testimony or the delayed disclosure
    must be shown. That has not been demonstrated here.
    Moreover, the testimony was corrected, and Clarke failed to
    demonstrate that the misleading content of the initial testimony
    could nevertheless have affected the judgment of the jury.
    Clarke’s Napue challenge thus also fails.
    To begin with, all parties agreed on a stipulation to be read
    to the jury exposing the government’s misleading presentation:
    The parties, meaning the government, the United States of
    America, and Mr. Clarke, stipulate and agree that the
    49
    campsite that FBI Agent Clauss and Sergeant Lucas
    testified about that was visited by Zion Clarke in the
    custody of law enforcement personnel on January 6, 2006,
    was not a location to where Mr. Maharaj was ever taken or
    at which he was ever held.
    J.A. 4713–14.
    That stipulation dispelled the confusion and set the
    groundwork for defense arguments countering the testimony.
    Indeed, it was materially indistinguishable from Clarke’s
    proposed curative instruction to the jury. 11 The only
    difference is that the stipulation did not include the phrase “it is
    now conceded by the government.”                 The defendants,
    however, have not demonstrated how the omission of that
    single phrase could have had any material impact on the jury’s
    consideration of all the relevant evidence presented in the case.
    Clarke’s counsel, moreover, used that stipulation in closing
    arguments to attack Agent Clauss and Sergeant Lucas’
    credibility. The jury thus was fully aware that both agents had
    misled them, and that the campsite to which Clarke had led law
    enforcement was not, in fact, a crime scene. That left the jury
    free to draw whatever inference it found more persuasive from
    Clarke’s actions.
    Defendants object that earlier disclosure would have
    permitted a more thoroughgoing presentation of a defense
    theory that Clarke led police to the wrong campsite precisely
    because he was not involved in the actual crime. But
    11
    Clarke’s counsel proposed the following stipulation: “[Y]ou
    heard testimony yesterday that Zion Clarke led agents to the
    campsite where Mr. Maharaj was held. It is now conceded by the
    government that that was not the campsite where Mr. Maharaj was
    held.” J.A. 3963.
    50
    defendants identify no evidence that Clarke was unable to
    present or any argument that he was precluded from making as
    a result of the tardy disclosure. Nor did Clarke request a
    continuance to develop this defense or ask that a mistrial be
    declared. The specific showing of concrete prejudice that
    Brady requires thus has not been made.
    Finally, the extensive evidence of Clarke’s guilt confirms
    that the ill-timed disclosure could not have affected the
    outcome. The jury heard Clarke’s four separate, “exhaustive
    and detailed” confessions, 
    Clarke, 767 F. Supp. 2d at 54
    , as
    well as corroborating testimony from Joseph and Percival.
    Most relevantly, the jury heard that, on the day after leading
    officers to the false campsite, Clarke led them to the site where
    Maharaj was held and ultimately buried. Accordingly, the
    defendants have not met their burden of demonstrating a
    reasonable probability that either the misleading testimony or
    its belated disclosure made a difference in the outcome of their
    cases.
    B.
    At trial, prosecutors asked Percival if Kenneth Pierre
    (Wayne Pierre’s brother, an uncharged, non-testifying, alleged
    co-conspirator) had said anything about Maharaj’s condition
    during the kidnapping. According to Percival’s reply,
    Kenneth Pierre had said that Demerieux “hit the man in his
    head with a big stone and dent his head.” J.A. 3436. But
    when Trinidadian police x-rayed Maharaj’s skull to investigate
    this claim, they found no such damage to his skull.
    Defendants did not learn of this x-ray evidence until the
    government turned over Agent Clauss’s grand jury testimony
    referring to the x-ray weeks after Percival testified.
    51
    Demerieux’s counsel moved for a mistrial, arguing that
    she would have obtained testimony from the person who
    conducted the x-ray if she had known earlier that it existed.
    But the prosecution noted that Dr. Des Vignes, the Trinidadian
    forensic pathologist who conducted Maharaj’s autopsy, had
    reported that he “did not see any fracture on [Maharaj’s] head,”
    and that all parties had that report long in advance of Percival’s
    testimony. J.A. 4610–11, Gov’t Br. 136. The district court
    denied the motion for a mistrial, finding that “the evidence was
    disclosed in time for [Demerieux’s] counsel to make effective
    use of it.” 
    Clarke, 767 F. Supp. 2d at 41
    .
    This Brady claim fails because there is no reasonable
    probability that earlier disclosure would have affected the
    jury’s verdict. First, the substance of the x-ray evidence—the
    absence of any fractures in Maharaj’s skull—had already been
    disclosed to the defense through Dr. Des Vignes’s report,
    which had been released to defense counsel well before
    Percival’s testimony. Thus the delayed release of the x-ray
    itself did not deprive the defense of its powerful ammunition
    for cross-examination.
    Second, Demerieux’s counsel made extensive use of the
    late-developing x-ray evidence to undermine Percival’s
    credibility, including by dramatically confronting the
    Trinidadian forensic pathologist with the x-ray of Maharaj’s
    skull showing no fracture. Demerieux’s closing argument
    underscored that the x-ray was “proof positive [that] what
    Jason Percival claims happened didn’t happen.” J.A. 5131.
    Demerieux fails to demonstrate how earlier release of the x-ray
    evidence would have made it any clearer to the jury that,
    whatever else Mr. Maharaj may have suffered, there was no
    support for Percival’s testimony that Demerieux hit Mr.
    Maharaj over the head with a rock.
    52
    Third, earlier access to the x-ray evidence could not have
    overcome the abundant evidence of Demerieux’s guilt,
    including his two confessions, and Joseph’s testimony that
    Demerieux guarded Maharaj and took part in his
    dismemberment. The reality is that the alleged assault with
    the rock formed a small part of a very large trial. Evidence of
    Demeriux’s involvement in a brutal kidnapping and in
    dismembering Mr. Maharaj’s body made the issue of whether
    Mr. Maharaj was also hit with a rock of little relevance. There
    thus is no reasonable possibility that the delayed disclosure
    affected the jury’s judgment, or that earlier disclosure would
    have made any difference on the jury’s consideration of the
    case.
    Finally, Demerieux’s Napue claim also fails. For many
    of the same reasons, he has not shown any reasonable
    probability that the misleading testimony influenced the jury’s
    verdict.
    C.
    In his initial confession after his arrest in 2006, Russell
    Joseph claimed that Ricardo Stevenson (who was not charged
    in this case) drove the “clear car” after Maharaj’s abduction. 12
    But at trial, Joseph testified that defendant De Four drove the
    clear car. The defense learned of the earlier confession a mere
    two hours before Joseph took the stand.
    De Four promptly raised a Brady objection. His counsel
    acknowledged, however, that the disclosure came in time for
    him “to use” the initial confession in cross-examination. In
    12
    The “clear car” was tasked with clearing the roads ahead of the
    get-away car, watching for police, and relaying information back.
    Gov’t Br. 8.
    53
    addition, the court granted a mid-trial continuance that
    afforded De Four’s counsel an “opportunity to conduct an
    additional investigation in Trinidad,” including five days to
    depose witnesses there. J.A. 4018.
    The district court subsequently denied De Four’s Brady
    motion, reasoning that the disclosure came early in a
    two-month long trial and that the lengthy continuance mid-trial
    had allowed the defendants to conduct further investigation.
    For that reason, the “disclosure occurred in time for defense
    counsel to use it effectively.” 
    Clarke, 767 F. Supp. 2d at 44
    .
    The court also held that any error was harmless, because the
    evidence of De Four’s guilt was “overwhelming.” 
    Id. at 46–
    47.
    The district court properly denied the Brady claim because
    the belated disclosure was not prejudicial. The record shows
    that De Four made powerful use of Joseph’s contradictory
    statements. De Four forced Joseph to admit on the stand and
    in front of the jury that he had lied to police when he accused
    an innocent man in a capital crime, and that he had done so to
    protect himself. And De Four’s counsel skewered the
    inconsistency in Joseph’s explanation for his lies, which was
    that Trinidadian police told him to leave the “soldiers” out of
    his account. As it turns out, both Stevenson and De Four were
    soldiers in the Trinidadian military, so there was no reason to
    finger Stevenson rather than De Four in the initial confession.
    But devastating cross-examination alone does not answer
    De Four’s claim of prejudice. He argues that the belated
    disclosure impaired his entire defense strategy.            More
    specifically, De Four argues that the pre-trial disclosure that
    Brady required would have allowed him to argue that Joseph
    was right the first time and that Stevenson was the real clear car
    driver. In so doing, De Four continues, his defense could have
    54
    undermined other critical testimony from Percival linking him
    to the crime by demonstrating a pattern of kidnappings in
    which Stevenson was the clear car driver.
    De Four, however, does not argue that earlier disclosure
    would have prompted a different strategy at trial. Instead, he
    claims that he would have made the same arguments that
    ultimately “foundered at trial for lack of proof,” Def. Br. 108,
    but that he would have provided more evidence to back them
    up. This is not a case, in other words, in which the defense
    would have had to turn on a dime to change its trial strategy in
    light of late-disclosed evidence. Instead, the initial Joseph
    confession fit hand-in-glove with the third-party defense
    strategy De Four’s counsel had planned all along.
    De Four claims that earlier disclosure would have alerted
    him to the importance of the Gopaul kidnapping, a previous
    crime in which Stevenson drove the clear car. Armed with
    that evidence, De Four argues that he would have had a better
    shot at convincing the jury that Percival had orchestrated a web
    of lies designed to frame him.
    The district court had already ruled that the government
    could not introduce evidence about the Gopaul kidnapping,
    given its potential to prejudice the jury. The record shows that
    De Four had ample time to reevaluate the importance of the
    Gopaul kidnapping and, if he desired, seek the court’s
    permission to incorporate it into his third-party defense. Early
    in June, just after the start of the trial, De Four had a transcript
    of Percival’s testimony identifying Stevenson as the clear car
    driver in the Gopaul kidnapping. In July, his counsel
    interviewed Stevenson in Trinidad during a week-long break in
    the trial. If De Four needed still more time to investigate after
    the disclosure of Joseph’s confession, he could have sought a
    55
    further continuance from the district court for that purpose.
    But he did not.
    On top of that, overwhelming evidence supported the
    jury’s decision to convict. De Four confessed at length to his
    participation in the crime.          His cell phone records
    corroborated that confession. And other witnesses confirmed
    De Four’s role in the crime, including one witness who
    testified that De Four actively participated in planning the
    abduction and later reported back on its success. Nothing in
    Joseph’s first confession or in the Gopaul case lends credibility
    to De Four’s argument that the police tricked him into
    confessing.
    De Four himself admits, in fact, that the jury was not
    “required to acquit him if they believed that he did not drive the
    clear car,” and argues only that “the Government’s case against
    him would surely have been weaker.” Def. Br. 108. Maybe
    so, but not so much weaker that it would have made a
    difference.     The evidentiary weight against De Four
    eliminates any reasonable probability that more or earlier
    investigation would have changed the outcome. 13
    Finally, all six defendants ask us to consider the
    cumulative impact of the Brady and Napue violations on the
    trial. That approach might work in a case where multiple
    errors affect the same defendant. If the prosecution fails to
    turn over two pieces of impeachment evidence, for example, an
    error-by-error approach might find no Brady violation in either
    case because for each scenario the evidence as a
    whole—including the evidence left unimpeached because of
    13
    The district court also denied Sealey’s Brady motion arising from
    this same tardy disclosure. Because Sealey’s arguments on appeal
    make no showing of prejudice, his claim fails as well.
    56
    the other alleged violation—would be enough to sustain the
    conviction. But the synergistic force of the omitted evidence
    considered together might well generate a reasonable
    probability of altering the evidentiary balance. Taking all the
    errors together thus keeps the Brady inquiry from devolving
    into a game of evidentiary whack-a-mole. See Kyles v.
    Whitley, 
    514 U.S. 419
    , 420 (1995) (“[T]he state’s disclosure
    obligation turns on the cumulative effect of all suppressed
    evidence favorable to the defense, not on the evidence
    considered item by item.”).
    But a cumulative approach does not help the defendants
    here. Each alleged violation only affected one of the
    defendants, and no two errors affected the same defendants.
    There simply was no defendant-specific cumulative impact
    that could alter the prejudicial effect of the prosecution’s
    substantial missteps.
    VI.
    Miranda Claims
    Sealey and Demerieux challenge the denial of their
    motions to suppress custodial statements that they gave to the
    Trinidadian police and to the FBI on the ground that their
    statements were obtained in violation of Miranda v. Arizona,
    
    384 U.S. 436
    (1966). Because the Trinidadian and FBI
    interrogations were independent and distinct, and because
    Sealey and Demerieux do not challenge the legal sufficiency of
    the Miranda warnings that the FBI gave before questioning, we
    hold that no violation of Miranda occurred. 14
    14
    De Four and Straker purport to join Demerieux’s and Sealey’s
    Miranda claims. Def. Br. 115 n.50. But “Fifth Amendment rights
    
    57 A. 1
    .
    The FBI began its investigation into the Maharaj hostage
    taking in April 2005, led by Special Agent Clauss. A separate
    investigation by Trinidadian police was already underway, led
    by Constable Phillip Forbes. Between April 2005 and
    January 2006, FBI Agent Clauss flew to Trinidad five times.
    He traveled there twice in April or May 2005, to begin the
    investigation. He returned in October, at which time the
    Trinidadian police brought a new witness to the U.S. Embassy
    for an interview with FBI agents. Constable Forbes remained
    present during the interview, but did not ask any questions.
    The following month, Agent Clauss returned to meet the
    new Trinidadian homicide detective assigned to the case,
    Sergeant Lucas. Agent Clauss informed Sergeant Lucas that
    the FBI had an ongoing investigation, but did not attempt to
    direct the investigation of the Trinidadian police. Agent
    Clauss explained that the Trinidadian police “were conducting
    their own investigation regarding what they believed was a
    homicide,” while he and his partner, FBI Agent Edgar Cruz,
    were investigating the hostage taking. J.A. 2479. “They
    were parallel investigations that were clearly similar in
    nature,” Agent Clauss testified, “but I didn’t feel a need to tell
    them what they should or shouldn’t do, nor would I be in a
    place to do that[.]” 
    Id. Agents Clauss
    and Cruz returned to Trinidad on January 3,
    2006, and met with Sergeant Lucas and his team of
    are, a fortiori, personal rights” in which De Four and Straker cannot
    share. Bryson v. United States, 
    419 F.2d 695
    , 699 (D.C. Cir. 1969).
    58
    investigators. Sergeant Lucas told Agent Cruz that the
    Trinidadian police planned to make their first arrests the
    following morning. True to their word, the Trinidadian police
    arrested Clarke and Demerieux the next day. The FBI was not
    invited to participate in the arrests. But Agents Clauss and
    Cruz did question Demerieux later that day with “members of
    the Trinidad[ian] police force[.]” United States v. Clarke, 
    611 F. Supp. 2d 12
    , 40 (D.D.C. 2009).
    Demerieux was again interviewed by the Trinidadian
    police and FBI agents on January 5th, “albeit briefly.”
    
    Clarke, 611 F. Supp. 2d at 40
    . The district court found that,
    during both interviews, Demerieux (i) was “notified of his
    rights” under both U.S. and Trinidadian law, (ii) “agreed to
    waive his rights,” (iii) “did not request a lawyer,” and (iv) “was
    not mistreated, threatened or coerced by law enforcement[.]”
    
    Id. at 41.
    Concluding that they had insufficient evidence to
    hold Demerieux, the Trinidadian police released him. 
    Id. After his
    arrest, Clarke, who was in Trinidadian custody,
    agreed to show the Trinidadian police a forest camp where he
    claimed Maharaj had been held. Agents Clauss and Cruz
    were invited to accompany a “large group of Trinidad[ian]
    police officers” to the site. 
    Clarke, 611 F. Supp. 2d at 26
    .
    The next day, Clarke identified the location “where the two
    containers holding the victim’s remains were buried.” 
    Clarke, 767 F. Supp. 2d at 21
    . The FBI later assisted with the
    recovery and identification of those remains. 
    Id. The Trinidadian
    police also arrested Straker on January
    6th. 
    Straker, 596 F. Supp. 2d at 84
    . A few days later,
    Sergeant Lucas informed Agent Clauss of the arrest. 
    Id. at 85.
    Sergeant Lucas then allowed Agent Clauss to interview
    Straker, remaining present during that interview. 
    Id. 59 On
    March 31, 2006, the Trinidadian police rearrested
    Demerieux, and Sergeant Lucas informed Agent Clauss of the
    arrest later that same day. 
    Clarke, 611 F. Supp. 2d at 41
    . The
    district court found that, when Agent Clauss and Sergeant
    Lucas spoke on the phone, they “did not discuss the substance
    of the investigation and Clauss did not attempt to direct the
    investigative efforts of the Trinidad[ian] police in any way.”
    
    Id. 2. When
    the Trinidadian police rearrested Demerieux, they
    “informed him of his rights under Trinidad[ian] law,” which
    include, among others, the right to remain silent, the right to
    speak with a legal representative, relative, or friend, and a
    warning that statements may be used against the accused in
    court. 
    Clarke, 611 F. Supp. 2d at 22
    , 41. Demerieux neither
    invoked his rights nor requested to contact a lawyer. Once at
    the police station, Demerieux “indicated that he wanted to give
    a statement.” 
    Id. at 42.
    The Trinidadian police reiterated the
    warnings required under Trinidadian law, and specifically
    advised Demerieux “that he had the right to contact a lawyer,
    relative or friend.” 
    Id. Demerieux reaffirmed
    his desire to
    give a statement. The Trinidadian police then contacted a
    Justice of the Peace, who met privately with Demerieux,
    questioning him about how the police had treated him and
    whether he had voluntarily agreed to give a statement. 
    Id. Demerieux said
    that he had been treated well and confirmed his
    desire to give a statement. The Justice of the Peace explained
    to Demerieux that he had the right to contact an attorney and
    informed him that he did not have to give a statement. 
    Id. Once that
    meeting concluded, “Demerieux was ready to give a
    formal statement.” 
    Id. 60 A
    Trinidadian officer transcribed Demerieux’s statement
    by hand, including “a certification that expressed Demerieux’s
    understanding of his rights, his waiver of his rights and his
    desire to give a statement.” 
    Clarke, 611 F. Supp. 2d at 42
    .
    That certification was read aloud to Demerieux, who indicated
    his understanding and signed his name. After finishing his
    statement, Demerieux was given the opportunity to review it,
    and the Trinidadian police also read it aloud to him. 
    Id. After Demerieux
    made several changes, he “signed the
    statement and acknowledged that it was true and had been
    made of his own free will.” 
    Id. Agents Clauss
    and Cruz arrived back in Trinidad the next
    day. 
    Clarke, 611 F. Supp. 2d at 43
    . The Trinidadian police
    “granted the FBI access to Demerieux,” who “agreed to
    conduct an interview with them.” 
    Id. Agent Clauss,
    though
    aware that Demerieux had given a statement the day before,
    testified that he had neither seen it nor discussed its substance
    with anyone from the Trinidadian police. 
    Id. Agents Clauss
    and Cruz then began their own interview
    with Demerieux. They presented him with an international
    advice of rights form, which they read to him “verbatim[.]”
    
    Clarke, 611 F. Supp. 2d at 43
    . The form generally advised
    Demerieux of his Miranda rights, but informed him that
    appointment of counsel could not be assured while he
    remained in foreign custody. 15 Agent Clauss also “explained
    Demerieux’s rights to him in a more informal way.” 
    Id. 15 The
    form stated in full:
    We are representatives of the U.S. government. According to
    our laws, you are entitled to certain rights. Before we ask you
    61
    any questions, we want to be certain that you understand such
    rights.
    You do not have to speak to us nor do you have to answer any
    questions. Even though you may have spoke[n] to the
    Trinidad[ian] authorities, you do not have to speak to us right
    now. If you do speak to us, everything that you say can be used
    against you in a court of law, in the United States or anywhere
    else.
    In the United States, you would have the right to seek advice from
    an attorney before we asked you any questions and to have an
    attorney with you during your interrogation. If you were in the
    United States and could not afford an attorney, you would be
    provided an attorney at no cost before submitting to any
    questions, if you so desired. Since you are not in our custody,
    nor are we in the United States, we cannot assure that you will
    have access to an attorney, nor can we assure that you will be
    provided with an attorney before we ask you any questions, or
    when we are asking such questions. If you wish to have an
    attorney but Trinidad[ian] authorities do not allow you access to
    one, or if they refuse to provide you an attorney at this time, you
    may opt not to speak to us. If you decide to speak to us without
    an attorney present, you reserve the right to decline to answer our
    questions at any time.
    Moreover, you should understand that if you choose not to speak
    to us, that fact may not be used as evidence against you in a court
    of law in the United States.
    It ends with the following statement and waiver of rights:
    I have read this notice of my rights and I understand what my
    rights are.
    I am prepared to give a statement and to answer questions.
    62
    “After the verbal warnings, Demerieux then initialed and
    signed the form, waiving his rights and agreeing to speak to the
    agents.” 
    Clarke, 611 F. Supp. 2d at 43
    . Demerieux never
    requested an attorney. 
    Id. The two
    FBI agents conducted the
    three-hour interview alone, without anyone from the
    Trinidadian police participating. 
    Id. The district
    court found
    that “the FBI treated Demerieux fairly and there is no evidence
    of any coercive tactics.” 
    Id. 3. The
    Trinidadian police arrested Sealey on August 8, 2006.
    
    Straker, 596 F. Supp. 2d at 102
    . Later that day, Sealey told a
    Trinidadian police officer that he wanted to talk about the
    kidnapping. In response, the officer “identified herself as a
    Trinidad[ian] police officer, and cautioned him as to his rights
    under Trinidad[ian] law[.]” 
    Id. After Sealey
    reiterated his
    desire to talk, the Trinidadian officer “requested the presence
    of a Justice of the Peace.” 
    Id. The Justice
    of the Peace spoke
    “privately with Sealey.” 
    Id. at 102.
    After that meeting, the
    Justice of the Peace advised the officer that Sealey wanted to
    speak with his father. 
    Id. Sealey, his
    father, and the Justice
    of the Peace then had a private meeting, at which, according to
    the Justice of the Peace’s handwritten certification, Sealey
    I do not wish to have an attorney at this time.
    I understand and know what I am doing.
    I have received no promises or threats nor have I been subjected
    to pressure or coercion of any sort.
    Dkt. 258-5 (Aug. 11, 2008).
    63
    confirmed that he was making his statement “knowingly and
    voluntarily.” 
    Id. Meanwhile, having
    been notified of Sealey’s arrest, FBI
    Agent Marvin Freeman arrived at the police station. 
    Straker, 596 F. Supp. 2d at 102
    . The Trinidadian officers did not
    “include Freeman in their preparations, having had no
    discussions with him about the investigation before that day.”
    
    Id. at 103.
    During Sealey’s interview by Trinidadian officers,
    Agent Freeman sat in an adjacent cubicle “over 10 feet away
    and could hear the interview taking place.” 
    Id. The Trinidadian
    police officers did not consult with Agent Freeman
    during the interview, and “Freeman did not make any
    suggestions to the officers about any areas of inquiry.” 
    Id. One Trinidadian
    police officer read Sealey his rights under
    Trinidadian law, and asked him to sign the following
    statement: “‘I, Michael Bourne, also known as Christopher
    Sealey and Boyie, wish to make a statement. I want someone
    to write down what I say. I have been told that I need not say
    anything unless I wish to do so and that whatever I say may be
    given in evidence. I have also been told that I have the right to
    retain a legal adviser.’” 
    Straker, 596 F. Supp. 2d at 103
    .
    Sealey signed the statement, and Sealey’s father and the Justice
    of the Peace signed as witnesses. 
    Id. Sealey confessed
    to his role in the kidnapping, and a
    Trinidadian police officer handwrote a transcript. 
    Straker, 596 F. Supp. 2d at 103
    . She then read the transcript to Sealey,
    who made corrections, each of which he signed. 
    Id. Sealey also
    handwrote the following statement:           “The above
    statement has been read to me, and I have been told that I can
    correct or add anything I wish. This statement is true. I have
    made it of my own free will.” 
    Id. Sealey’s father
    and the
    Justice of the Peace signed as witnesses, and the Justice of the
    64
    Peace wrote an additional certification about the interview,
    “summarizing his initial private meeting with Sealey and his
    father and Sealey’s waiver of rights, and then confirming that
    Sealey had been read the full statement in the presence of his
    father before making the handwritten certification that it was
    correct.” 
    Id. at 104.
    After they finished questioning Sealey, the Trinidadian
    police allowed Agent Freeman to interview him. 
    Straker, 596 F. Supp. 2d at 104
    . Agent Freeman read Sealey his rights
    based on an “‘international advice of rights’ form.” Id.; see
    supra note 15. Sealey signed the form, and his father, who
    remained present throughout, signed as a witness, along with
    another Trinidadian police officer. 
    Id. at 105.
    The district
    court found that “Sealey did not ask to stop the interview, nor
    did he appear to be in distress or discomfort.” Straker, 596 F.
    Supp. 2d. at 105.
    B.
    Before trial, Demerieux moved to suppress his March 31st
    statement to the Trinidadian police, and his April 1st statement
    to the FBI. 
    Clarke, 611 F. Supp. 2d at 40
    . Sealey likewise
    moved to suppress the statements he made on August 8, 2006,
    both to the Trinidadian police and to the FBI. Straker, 596 F.
    Supp. 2d at 105.
    As relevant here, both argued that the statements were
    inadmissible because the Trinidadian police and the FBI were
    engaged in a “joint venture,” and accordingly Miranda
    warnings were required before the interviews by the
    Trinidadian police. Id.; 
    Clarke, 611 F. Supp. 2d at 40
    . They
    also contended that the statements should be suppressed
    because they were involuntary. See 
    Straker, 596 F. Supp. 2d at 105
    ; 
    Clarke, 611 F. Supp. 2d at 40
    .
    65
    The district court rejected both motions. See 
    Straker, 596 F. Supp. 2d at 108
    –09; 
    Clarke, 611 F. Supp. 2d at 44
    –45.
    Relying on the government’s concession, the court assumed
    that Miranda applies to FBI questioning of non-resident aliens
    held in foreign custody abroad. 
    Clarke, 611 F. Supp. 2d at 29
    & n.12 (quoting Gov’t Opp’n to Clarke Mot. at 20 (Dkt. No.
    353)); see also 
    id. at 43–44.
    The court noted, however, that
    Miranda did not govern the interrogations by the Trinidadian
    police unless those interrogations were “the product of a joint
    venture,” which exists when “‘United States law enforcement
    agents actively participate in the questioning of the defendant
    or the foreign officials act as agents or virtual agents of the
    United States.’” 
    Id. at 43–44
    (quoting Straker, 
    596 F. Supp. 2d
    at 106).
    With respect to Demerieux’s March 31st statement to the
    Trinidadian police, the court found no “active participation” by
    the FBI, as Agents “Clauss and Cruz did not even arrive in
    Trinidad until the following day[.]” 
    Clarke, 611 F. Supp. 2d at 44
    . The district court further determined that the “two law
    enforcement entities were conducting independent
    investigations, they were not sharing information, and the FBI
    was in no way directing the activities of the Trinidad[ian]
    police.” 
    Id. Finding “no
    evidence that the Trinidad[ian]
    police were acting as agents, or virtual agents, of the FBI at the
    time he made his statement on March 31,” the district court
    concluded that there was no joint venture. 
    Id. The court
    further found that “Demerieux was well aware of his rights,
    voluntarily agreed to waive those rights, and gave a statement
    to the Trinidad[ian] police of his own free will.” 
    Id. The court
    reached the same conclusion about the voluntariness of
    Demerieux’s April 1st statement to the FBI. 
    Id. at 44–45.
                                    66
    With respect to Sealey’s August 8th statements, the
    district court found “simply no evidence” that the separate
    interviews of Sealey by the Trinidadian police and the FBI
    amounted to a joint venture. Straker, 
    596 F. Supp. 2d
    at 106.
    The district court found that the testimony “overwhelmingly
    established that there were two distinct interviews[.]” 
    Id. The court
    also determined that “the Trinidad[ian] police and
    Freeman were not acting jointly with respect to the
    investigation of Sealey at the time the interview took place,”
    finding that the FBI (i) “did not participate in Sealey’s arrest on
    August 8, 2006”; (ii) “was [not] even remotely involved in
    setting up Sealey’s interview with the Trinidad[ian] police”;
    and (iii) “was not allowed to participate in the Trinidad[ian]
    officers’ interview of Sealey, observe the interview, or submit
    any questions,” but was instead “only permitted to conduct [its]
    own separate interview.” 
    Id. at 106–07.
    Thus, “under even a
    broad view of the ‘joint venture’ standard,” the district court
    concluded, “[w]hatever information-sharing or cooperation
    might have occurred with respect to other defendants, there is
    nothing to support a finding that the Trinidad[ian] police and
    the FBI were acting ‘jointly’ on August 8, 2006[.]” 
    Id. at 107.
    C.
    The parties dispute the standard of review applicable to the
    joint-venture question. Demerieux and Sealey contend that
    the district court’s factual findings are reviewed for clear error,
    but that the ultimate question of whether the facts found
    constitute a joint venture is a legal question reviewed de novo.
    That is analogous to how we review a district court’s
    conclusion that, under the totality of the circumstances, an
    accused “waived his fifth and six[th] amendment rights
    ‘voluntarily, knowingly, and intelligently.’” United States v.
    Yunis, 
    859 F.2d 953
    , 958 (D.C. Cir. 1988) (quoting 
    Miranda, 384 U.S. at 444
    ). The government, by contrast, argues that
    67
    our review is for clear error only. We need not resolve the
    question in this case because, even reviewing de novo, we
    affirm.
    D.
    1.
    We note at the outset that the government concedes that
    the Fifth Amendment privilege against self-incrimination
    protects nonresident aliens facing criminal trial in the United
    States, even when, as here, the questioning by federal
    authorities took place abroad. Gov’t Br. 187–88 n.93
    (“Below, the government conceded the applicability of the
    Fifth Amendment to the FBI’s overseas actions.”); Oral Arg.
    Tr. 135:18–19 (“[W]e appropriately concede it[.]”); see also In
    re Terrorist Bombings of U.S. Embassies in E. Africa, 
    552 F.3d 177
    , 198–201 (2d Cir. 2008) (so concluding). Relatedly,
    despite some equivocation below, see 
    Clarke, 611 F. Supp. 2d at 29
    n.12, the government has conceded on appeal the
    applicability of Miranda to interrogations by U.S. authorities
    of individuals in foreign police custody, see Oral Arg. Tr. 135;
    Gov’t Br. 187–88 n.93. For those reasons, we assume,
    without deciding, that Miranda applies to statements obtained
    by U.S. authorities from suspects held in foreign custody
    abroad.
    The Fifth Amendment’s self-incrimination clause
    provides that no “person” “shall be compelled in any criminal
    case to be a witness against himself.” U.S. CONST. AMEND. V.
    As the Supreme Court held in Miranda, that privilege against
    compelled self-incrimination is “applicable during a period of
    custodial 
    interrogation.” 384 U.S. at 460
    –61. That is
    because “the compulsion to speak in the isolated setting of the
    police station may well be greater than in courts or other
    68
    official investigations,” 
    id. at 461,
    which “heightens the risk
    that an individual will not be ‘accorded his privilege under the
    Fifth Amendment . . . not to be compelled to incriminate
    himself,’” Dickerson v. United States, 
    530 U.S. 428
    , 435
    (2000) (quoting 
    Miranda, 384 U.S. at 439
    ) (alterations in
    original).
    To protect against that risk, Miranda set forth “concrete
    constitutional guidelines for law enforcement agencies and
    courts to 
    follow.” 384 U.S. at 442
    . “Those guidelines
    established that the admissibility in evidence of any statement
    given during custodial interrogation of a suspect would depend
    on whether the police provided the suspect with four
    warnings”: that “a suspect ‘has the right to remain silent, that
    anything he says can be used against him in a court of law, that
    he has the right to the presence of an attorney, and that if he
    cannot afford an attorney one will be appointed for him prior to
    any questioning if he so desires.’” 
    Dickerson, 530 U.S. at 435
    (quoting 
    Miranda, 384 U.S. at 479
    ).
    A different rule applies, however, to statements obtained
    abroad by foreign officials. See Wayne R. LaFave et al., 2
    Criminal Procedure § 6.10(d) (3d ed. 2013) (“[T]hough a
    defendant may be entitled to keep out of a prosecution in this
    country a confession by him which was involuntarily given to a
    foreign policeman, he may not obtain the suppression of a
    confession obtained by such an official merely because the
    Miranda warnings were not given.”). As a prophylactic rule,
    Miranda safeguards the constitutional privilege against
    compelled self-incrimination by deterring negligent or willful
    police misconduct that could impinge upon the Fifth
    Amendment right. See Oregon v. Elstad, 
    470 U.S. 298
    , 308
    (1985) (noting a principal aim of Miranda is “deterrence”);
    Michigan v. Tucker, 
    417 U.S. 433
    , 447 (1974) (discussing the
    “deterrent purpose of the exclusionary rule”). But because the
    69
    Miranda exclusionary rule would “have little, if any, deterrent
    effect upon foreign police officers,” In re Terrorist 
    Bombings, 552 F.3d at 202
    , courts have held that “statements obtained
    from a defendant by foreign law enforcement officers, even
    without Miranda warnings, generally are admissible” as long
    as they are “voluntary,” United States v. Abu Ali, 
    528 F.3d 210
    ,
    227 (4th Cir. 2008); see also LaFave, supra, § 6.10(d) n.59 (it
    is “commonly assumed” that the voluntariness requirement
    still applies to confessions obtained during overseas
    interrogations by foreign officers, but “it may well be that . . .
    the defendant can object only if the confession was obtained by
    methods making its reliability suspect or, perhaps, by methods
    which ‘shock the conscience’”). 16
    Under the “joint venture” doctrine, custodial statements
    obtained by foreign officials without Miranda warnings are
    inadmissible in United States courts if those officials were
    “engaged in a joint venture with, or . . . were acting as agents
    of, United States law enforcement officers.” Abu 
    Ali, 528 F.3d at 228
    . Demerieux and Sealey argue that the FBI and the
    Trinidadian police were engaged in such a coordinated, joint
    investigation, and accordingly the statements given to the
    Trinidadian police without Miranda warnings must be
    16
    We have never decided what standard determines the
    admissibility of statements obtained abroad by foreign police
    officers, though it has been suggested that the ordinary voluntariness
    standard governs. See 
    Yunis, 859 F.2d at 971
    (Mikva, J., specially
    concurring) (arguing that voluntariness standard should apply
    because, “[i]n Bram v. United States, 
    168 U.S. 532
    (1897), the Court
    excluded a confession from an American trial, notwithstanding that
    the coercive interrogation was conducted by a foreign police officer
    in a foreign country”). We need not decide that question today
    because Demerieux and Sealey do not dispute voluntariness distinct
    from their Miranda claims.
    70
    suppressed. Demerieux and Sealey also argue that their
    statements to the FBI should have been suppressed under
    Missouri v. Seibert, 
    542 U.S. 600
    (2004), which generally
    prevents police from sanitizing an unwarned statement by
    giving the suspect after-the-fact Miranda warnings and then
    having the suspect repeat the incriminating statement.
    2.
    The “joint venture” doctrine ensures that United States
    law enforcement agents cannot circumvent their obligations
    under Miranda just by outsourcing custodial interrogation to
    foreign agents while still “actively participat[ing] in the
    questioning conducted by foreign authorities,” United States v.
    Yousef, 
    327 F.3d 56
    , 145 (2d Cir. 2003), or by having “the
    foreign officials act as [their] agents or virtual agents,” Straker,
    
    596 F. Supp. 2d
    at 106.
    Demerieux and Sealey acknowledge that the FBI did not
    participate at all, let alone “actively participate,” 
    Yousef, 327 F.3d at 145
    , in the Trinidadian police interrogations, Oral Arg.
    Tr. 119:25–120:1 (“[T]his was clearly not a joint venture in the
    questioning[.]”). And Demerieux and Sealey do not attack as
    clear error the district court’s factual findings concerning the
    operational independence of the interrogations. 
    Id. at 109:8–
    9. Indeed, Demerieux and Sealey concede that, if the inquiry
    is confined to the days of their respective interrogations, there
    is nothing to support a conclusion that the Trinidadian police
    and the FBI were acting jointly. 
    Id. at 109:11–14.
    Focusing instead on several preceding incidents of
    cooperation between the two law enforcement agencies,
    Demerieux and Sealey assert that the cooperation rose to the
    level of a “prior joint investigative venture” from which the
    interrogations by the Trinidadian police “sprang.” Def. Br.
    71
    120. They point in particular to: (i) Agent Clauss’s meeting
    with the Trinidadian police in late 2005 and the resulting
    exchange of information between the two law enforcement
    agencies; (ii) the Trinidadian police’s aid to the FBI in securing
    an interview of a cooperating witness in January 2006; (iii) the
    joint trips by the FBI and the Trinidadian police to investigate
    campsite where Maharaj was said to be held and where
    Maharaj was buried, and the forensic assistance provided by
    the FBI during the discovery and autopsy of Maharaj’s
    remains; and (iv) the joint interview of Straker by the FBI and
    the Trinidadian police on January 9, 2006.
    We need not decide whether the joint-venture inquiry
    turns on the amount of coordination across the whole
    eighteen-month, multi-defendant investigation or only in the
    discrete interrogations to which Miranda could apply.
    Compare United States v. Emery, 
    591 F.2d 1266
    , 1268 (9th
    Cir. 1978) (inquiring into the totality of the involvement of
    U.S. law enforcement agents in the investigation and arrest of
    suspects), with Yousef, 
    327 F.3d 145
    –46 (inquiring into U.S.
    law enforcement officers’ participation in the interrogations to
    which Miranda could have applied). Even assuming that the
    nature of the full investigative relationship governs, the
    isolated incidents of routine cooperation between the
    Trinidadian police and the FBI do not amount to the type of
    closely coordinated investigative effort that would trigger the
    joint venture doctrine.
    To begin with, there was no “coordination and direction”
    of the Trinidadian investigation by the FBI. See Abu 
    Ali, 528 F.3d at 229
    . Nor is there evidence of “active” or “substantial”
    participation by U.S. law enforcement agents in the
    Trinidadian investigation. While FBI officers were physically
    present during one Trinidadian interrogation, such silent
    observation does not make the interrogation the FBI’s own for
    72
    purposes of Miranda. See 
    id. (“[M]ere presence
    at an
    interrogation does not constitute the ‘active’ or ‘substantial’
    participation necessary for a ‘joint venture[.]’”); see also
    Pfeifer v. Bureau of Prisons, 
    615 F.2d 873
    , 877 (9th Cir. 1980);
    Kilday v. United States, 
    481 F.2d 655
    , 656 (5th Cir. 1973).
    Nor is it enough that foreign law enforcement agents granted a
    U.S. law enforcement agent permission to question a suspect.
    See United States v. Heller, 
    625 F.2d 594
    , 599–600 & n.7 (5th
    Cir. 1980) (no joint venture where U.S. officers had to get
    permission from British authorities to interview the suspect,
    Mirandized the suspect when questioning him, and did not
    discuss with British authorities the separate un-Mirandized
    interrogation those authorities had conducted).
    Likewise, the forensic assistance provided by the FBI
    during the recovery, autopsy, and identification of Maharaj’s
    remains does not trigger Miranda both because the assistance
    was limited in time and scope, and because it served the FBI’s
    own independent investigative efforts. See United States v.
    Bagaric, 
    706 F.2d 42
    , 69 (2d Cir. 1983) (“[C]lose cooperation
    between American and Canadian officials [was] insufficient to
    upset [the trial court’s] finding that [the Canadian official]
    conducted the search on his own country’s authority and in
    connection with an ongoing Canadian investigation.”); see also
    
    Heller, 625 F.2d at 599
    –600 (no joint venture when, inter alia,
    participation by U.S. law enforcement officers in suspect’s
    arrest “was peripheral at most”); United States v. Mundt, 
    508 F.2d 904
    , 906–07 (10th Cir. 1974) (Miranda inapplicable
    where U.S. law enforcement officer “merely . . . played a
    substantial part in the events which led up to the arrest of
    [defendant], but once the arrest was made the Peruvian Police
    took over”).
    Instead, the types of joint ventures that have triggered
    Miranda have involved levels of coordination and interaction
    73
    far more extensive than what occurred here. There is no
    evidence in this case, for example, that the Trinidadian police
    were “acting on behalf of” the FBI “in an effort to extradite”
    Demerieux and Sealey to the United States. Cranford v.
    Rodriguez, 
    512 F.2d 860
    , 863 (10th Cir. 1975).
    Nor is this case like 
    Emery, 591 F.2d at 1268
    , on which
    Demerieux and Sealey heavily rely. There, agents of the U.S.
    Drug Enforcement Agency contacted Mexican officials about
    suspected drug activity, coordinated surveillance, supplied an
    undercover agent as the pilot for a drug transport plane in a
    Mexican sting operation, signaled when to arrest the suspects
    after determining that drugs were located in suitcases, and were
    present at the suspects’ interrogation. See 
    id. Such extensive
    coordination, active participation, and direction by U.S. law
    enforcement officers far surpasses the limited cooperation
    between the Trinidadian police and the FBI here. 17
    Indeed, if the isolated and infrequent interactions and
    courtesies that occurred here sufficed, all manner of routine
    international cooperation would be subject to Miranda’s
    strictures regardless of whether U.S. law enforcement officers
    have any practical authority over or responsibility for the
    interrogations and investigative measures undertaken by
    foreign officials. Miranda is a prophylaxis designed to
    regulate and deter the coercive conduct of domestic law
    enforcement officers. See In re Terrorist 
    Bombings, 552 F.3d at 202
    . It is not meant to police independent foreign
    investigative activities that U.S. law enforcement officers do
    not direct and cannot control.
    17
    We have found no case, and defendants have cited none, in which
    the type of occasional interactions at issue here amounted to a joint
    venture.
    74
    3.
    Because there was no joint venture, Seibert does not
    require suppression either. In Seibert, the Supreme Court
    evaluated a police protocol under which the interrogating
    officer deliberately withheld Miranda warnings until the
    suspect confessed, and then gave the full Miranda warnings
    post hoc before having the suspect repeat the confession.
    
    Seibert, 542 U.S. at 605
    –07 (plurality).
    When confronted with such question-first-and-warn-later
    tactics, courts must determine “whether it would be reasonable
    to find that in these circumstances the warnings could function
    ‘effectively’ as Miranda requires.” 
    Seibert, 542 U.S. at 611
    –
    12. The Seibert plurality focused on such factors as “the
    completeness and detail of the questions and answers in the
    first round of interrogation, the overlapping content of the two
    statements, the timing and setting of the first and the second,
    the continuity of police personnel, and the degree to which the
    interrogator’s questions treated the second round as continuous
    with the first.” 
    Id. at 6
    15. Concurring in the judgment,
    Justice Kennedy stated that he “would apply a narrower test
    applicable only in the infrequent case . . . in which the two-step
    interrogation technique was used in a calculated way to
    undermine the Miranda warning.” 
    Id. at 6
    22 (Kennedy, J.,
    concurring in the judgment).
    In light of the fractured decision in Seibert, courts have
    debated whether the plurality opinion’s multifactor test
    controls, or whether Justice Kennedy’s concurrence is the
    narrower rationale that is binding under Marks v. United
    States, 
    430 U.S. 188
    , 193 (1977). Compare United States v.
    Courtney, 
    463 F.3d 333
    , 338 (5th Cir. 2006) (“[W]e find
    Seibert’s holding in Justice Kennedy’s opinion concurring in
    75
    the judgment.”), with United States v. Heron, 
    564 F.3d 879
    ,
    884 (7th Cir. 2009) (“[T]he Marks rule is not applicable to
    Seibert,” as “Justice Kennedy’s intent-based test was rejected
    by both the plurality opinion and the dissent[.]”).
    We need not pick sides in that debate because (i) Seibert
    does not apply on these facts and, even if it did,
    (ii) Demerieux’s and Sealey’s statements were admissible
    under both the plurality’s and Justice Kennedy’s tests.
    First, Seibert applies only when the accused is questioned
    first, then warned later. 
    See 542 U.S. at 611
    –12. That did not
    happen here. The district court found—and Demerieux and
    Sealey do not dispute—that the Trinidadian police’s warnings
    under Trinidadian law were “functionally equivalent” to those
    required by Miranda. Straker, 
    596 F. Supp. 2d
    at 107 n.24;
    
    Clarke, 611 F. Supp. 2d at 44
    n.27; see also Oral Arg. Tr.
    111:9–18. Simply put, there was no two-step interrogation
    because (i) the Trinidadian police and the FBI were not acting
    in concert and, in any event, (ii) both gave warnings the
    adequacy of which under Miranda Demerieux and Sealey do
    not challenge.
    Second, Justice Kennedy’s test applies only when police
    deliberately use a two-step interrogation to thwart Miranda.
    See 
    Seibert, 542 U.S. at 622
    (Kennedy, J., concurring in the
    judgment). Such deliberate evasion is absent in this case.
    Demerieux and Sealey concede both that “there was no
    evidence of a protocol that directed the FBI to swoop in after
    [the Trinidadian police] secured a confession,” Reply Br. 59,
    and that the Trinidadian police and the FBI were not acting
    jointly on the days of their interrogations, see Oral Arg. Tr.
    119:25–120:6. There accordingly was no “interrogation
    technique designed to . . . undermine[] the Miranda warning
    76
    and obscure[] its meaning.” 
    Seibert, 542 U.S. at 618
    (Kennedy, J., concurring in the judgment).
    Third, even under the Seibert plurality’s multifactor test,
    Demerieux’s and Sealey’s claim would fail. Although both
    the Trinidadian police and the FBI thoroughly questioned
    Demerieux and Sealey, and thus elicited confessions the
    content of which largely overlaps, those two factors do not
    outbalance the other considerations demonstrating the efficacy
    of the intervening FBI Miranda warnings. To start, given the
    timing and setting of the first statement to the Trinidadian
    police and the second statement to the FBI, “a reasonable
    person” “could have seen” the FBI’s questioning “as a new and
    distinct experience” during which he retained “a genuine
    choice whether to follow up on the earlier admission” to the
    Trinidadian police. 
    Seibert, 542 U.S. at 615
    –16. The
    Trinidadian police began their interviews by apprising
    Demerieux and Sealey of their rights under Trinidadian law,
    while the FBI informed them of their rights under U.S. law.
    Those separate rounds of separate warnings not only made
    Demerieux and Sealey aware that each round of questioning
    was distinct, but also reminded them on each occasion that they
    had the right to remain silent. The distinctness of the
    interrogations is particularly stark for Demerieux, whose
    interrogation by the FBI came a day after his interrogation by
    the Trinidadian police. See 
    Clarke, 611 F. Supp. 2d at 42
    .
    Furthermore, unlike in Seibert, there was a sharp
    discontinuity of police personnel, and the FBI did not “treat[]
    the second [interrogation] as continuous with the first.”
    
    Seibert, 542 U.S. at 615
    . Not only were the FBI agents who
    interrogated Demerieux and Sealey different from the
    Trinidadian police officers who initially questioned them, but
    the FBI agents represented an entirely different law
    enforcement authority from an entirely different country.
    77
    Equally importantly, the FBI agents did not refer back to
    the prior Trinidadian interrogations in an effort to elicit the
    same confessions. In Seibert, by contrast, the “same officer”
    who conducted the first, unwarned interrogation returned “only
    15 to 20 minutes” later and led the suspect “over the same
    ground 
    again.” 542 U.S. at 613
    , 616. Indeed, that officer
    “set the scene” for the second round of questioning “by saying
    ‘we’ve been talking for a little while about what happened on
    Wednesday the twelfth, haven’t we?’” 
    Id. at 6
    16. And when
    the suspect equivocated or departed from her prior statement,
    the officer referred “back to the confession already given,”
    reinforcing the impression “that the further questioning was a
    mere continuation” of the earlier interrogation. 
    Id. Here, a
    reasonable person would have viewed the Trinidadian police’s
    and the FBI’s interrogations as two “independent
    interrogations.” 
    Id. at 6
    14.
    VII.
    Edwards Claim
    Defendant Straker separately challenges the denial of his
    motion to suppress the statement he gave to the FBI on July 29,
    2007, on the ground that it was obtained after he had invoked
    the right to counsel, in violation of Edwards v. Arizona, 
    451 U.S. 477
    (1981). Because Straker voluntarily reinitiated
    communication with the FBI, we reject his claim. 18
    18
    De Four and Sealey purport to join Straker’s argument. Def. Br.
    133 n.58. However, they cannot vicariously invoke Straker’s
    personal Fifth and Sixth Amendment protections under Edwards.
    See supra note 
    14, supra
    ; see also United States v. Sabatino, 
    943 F.2d 94
    , 96 n.1 (1st Cir. 1991) (“Sixth Amendment rights . . . are
    
    78 A. 1
    .
    The Trinidadian police arrested Straker on January 6,
    2006, interrogating him once that day and again the next.
    
    Straker, 596 F. Supp. 2d at 84
    –85. On both occasions the
    Trinidadian police informed Straker of his rights under
    Trinidadian law before questioning him, including the “right to
    remain silent, the right to communicate with a legal
    representative, relative, or friend, and a caution that the
    statement may be used against the accused.” 
    Id. at 85.
    Straker denied any knowledge of the kidnapping or killing.
    
    Id. A day
    later, on January 8th, Straker met with his attorney,
    who told “Straker not to sign any documents or speak to
    anyone.” 
    Id. On January
    9th, Sergeant Lucas allowed the FBI to
    interview Straker. Straker, 
    596 F. Supp. 2d
    at 85. During the
    interview, Sergeant Lucas and three FBI agents—Clauss, Cruz,
    and Freeman—sat at the table across from Straker. 
    Id. Agent Clauss
    read the standard FBI international
    advice-of-rights form to Straker, advising him of his Miranda
    rights with the standard caveat that appointment of counsel
    cannot be assured while he remains in foreign custody. 
    Id. at 86.
    Discussions were “calm [and] relaxed.” J.A. 2187.
    Straker’s conversational tone left both Sergeant Lucas and
    Agent Cruz with the “distinct impression that [Straker] wanted
    to cooperate,” J.A. 2291 (Agent Cruz), and was “trying to
    make a deal or something,” J.A. 2161 (Sgt. Lucas).

    443 U.S. 368
    , 380 (1979)).
    79
    About halfway through the interview, Straker told the
    agents that he had an attorney. Straker, 
    596 F. Supp. 2d
    at 86.
    Straker said that he did not wish to talk about the details of the
    case “at this time,” but would “rather talk to my attorney before
    I talk any further.” J.A. 2257. The session continued “for
    another hour or so,” with “intermittent questions from the FBI
    about Straker’s biographical and family information” and
    Straker otherwise “‘leading most of the conversation.’”
    Straker, 
    596 F. Supp. 2d
    at 86. Near the end of the session,
    Straker said that “‘after having access to his attorney, he would
    be willing to speak to the agents.’” 
    Id. at 87.
    Agent Clauss
    then advised Straker that, “after he talked to his attorney, if he
    wanted to make an attempt to contact” them, they “would be
    willing to follow up with him at that point.” J.A. 2191. To
    that end, Agent Freeman gave Straker his card, which
    contained his contact information at the U.S. Embassy in
    Trinidad. Straker, 
    596 F. Supp. 2d
    at 87. The FBI then
    ended the interview. 
    Id. “[A]bout two
    weeks” later, having met with his lawyer in
    the interim, Straker attempted to contact Agent Freeman by
    telephone. Straker, 
    596 F. Supp. 2d
    at 88–89, 94. There is
    no recording of Straker’s message, but Agent Freeman testified
    that “it was to the effect of ‘this is Anderson Straker; can you
    contact me?’” 
    Id. at 89.
    Agent Freeman never returned
    Straker’s call, however, because he was advised “not to do so”
    by a Trinidadian official in light of Straker’s “legal
    representation” in Trinidadian courts. 
    Id. at 89.
    Straker was formally charged by the Trinidadian
    authorities on January 10, 2006, and he remained “in custody
    in Trinidad” for the next eighteen months. Straker, 596 F.
    Supp. 2d at 87–89. The FBI did not attempt to contact him at
    any point during those intervening months. 
    Id. at 89.

    Straker was formally indicted in the United States on
    September 20, 2006. Straker, 
    596 F. Supp. 2d
    at 89. But he
    remained in Trinidadian custody until his extradition to the
    United States on July 29, 2007. 
    Id. After formally
    arresting
    Straker at the airport in Trinidad, Agent Clauss orally advised
    Straker of his Miranda rights and gave him an FBI advice of
    rights form, which included the full Miranda warnings. 
    Id. at 89
    & n.13. Straker signed the form’s waiver of rights,
    indicating that “I have read this statement of my rights and I
    understand what my rights are. At this time, I am willing to
    answer questions without a lawyer present.” 
    Id. at 89.
    Both
    Clauss and Cruz signed as witnesses, and, according to their
    testimony, “Straker appeared willing to sign and . . . did not
    raise any questions about his rights.” 
    Id. The FBI
    interviewed Straker upon arrival in Puerto Rico.
    Straker, 
    596 F. Supp. 2d
    at 90. Straker did not ask to stop the
    questioning “and overall seemed ‘cooperative.’”             
    Id. According to
    FBI notes, Straker “acknowledged having a role
    in planning the kidnapping of Balram Maharaj and described
    the roles of several co-defendants.” 
    Id. B. Straker
    moved to suppress his July 29, 2007 statement to
    the FBI. He argued that, because he had invoked his right to
    counsel when the FBI interviewed him in Trinidad in January
    2006, the FBI was barred from subjecting him to further
    custodial interrogation eighteen months later when he was
    extradited to the United States. See 
    Straker, 596 F. Supp. 2d at 84
    . Straker grounded his argument on Edwards v. Arizona,
    which held that, once a suspect invokes his right to counsel,
    police generally may not obtain a waiver of that right just by
    81
    later reopening the 
    interrogation. 451 U.S. at 484
    –85.
    Instead, the suspect must himself reinitiate any discussion. 
    Id. Straker argued
    that he had done nothing to invite a resumption
    of questioning, thus rendering his waiver of Miranda rights
    invalid.
    The district court denied Straker’s motion. Straker, 
    596 F. Supp. 2d
    at 99–100. The court again relied on the
    government’s concession that “the Fifth Amendment privilege
    against self-incrimination protects nonresident aliens facing a
    criminal trial in the United States even where the questioning
    by United States authorities takes place abroad.” 
    Id. at 90–91.
    The district court then noted that Edwards establishes a
    “bright-line” rule “barring police interrogation of a subject
    who has invoked his right to counsel unless the subject initiates
    further communications with the police.” 
    Id. at 91
    (citing
    Arizona v. Roberson, 
    486 U.S. 675
    , 681–82 (1988); Minnick v.
    Mississippi, 
    498 U.S. 146
    , 151–52 (1990)). Describing it as a
    “close call,” the district court concluded that the message
    Straker left for Agent Freeman a few weeks after the January 9,
    2006 interview “initiated” further communication with the FBI
    under Oregon v. Bradshaw, 
    462 U.S. 1039
    (1983) (plurality),
    and that Straker had voluntarily, knowingly, and intelligently
    waived his right to counsel. Straker, 
    596 F. Supp. 2d
    at 93–
    95.
    In so concluding, the district court credited the testimony
    of Agent Freeman, finding that Straker left “at least one voice
    mail message about two weeks after the January 9 interview,
    asking Freeman to call him.” Straker, 
    596 F. Supp. 2d
    at 94.
    The court also considered “the context in which the message
    was left” to be “important,” stressing that Straker had said in
    the first interview that “he wanted to leave the door open for
    further discussions” after he consulted his lawyer. 
    Id. Straker then,
    of his own initiative, used the business card that
    82
    the FBI agent had left him “for th[e] purpose” of reopening
    communication to call and ask Agent Freeman to speak with
    him. 
    Id. In the
    district court’s view, that sequence of events
    could “reasonably be construed to indicate that [Straker’s]
    initiation of communication [was] directed toward the
    investigation.” 
    Id. The district
    court also concluded that, upon his
    extradition, Straker voluntarily, knowingly, and intelligently
    waived his Fifth Amendment right to counsel before giving his
    July 29, 2007 statement, finding that (i) Straker had
    “familiarity generally with the Miranda warnings from his
    January 2006 interview”; (ii) Straker was properly advised of
    his Miranda rights by Agent Clauss on July 29, 2007 and
    agreed to waive those rights by signing the waiver on the FBI’s
    advice of rights form; (iii) the only “coercive circumstance” on
    July 29th was the handcuffs Straker wore; and (iv) the FBI had
    no contact with Straker in the eighteen months between the
    January 2006 interview and the July 2007 interview, leaving no
    opportunity for the FBI to “badger” Straker into signing the
    waiver. 
    596 F. Supp. 2d
    at 95–96. Finally, the court held
    that this waiver applied as well to Straker’s Sixth Amendment
    right to counsel post-indictment. 
    Id. at 100
    (citing Patterson
    v. Illinois, 
    487 U.S. 285
    (1988)).
    C.
    The district court’s factual findings are reviewed for clear
    error. See 
    Yunis, 859 F.2d at 958
    . The government argues
    that “initiation” is a fact question reviewed for clear error.
    Straker argues, however, that the ultimate question of whether
    those facts amount to an “initiation” under Edwards is
    reviewed de novo. Straker is correct. The question whether a
    given set of facts meets the legal threshold needed to overcome
    Edwards’s prophylactic protection of Fifth and Sixth
    83
    Amendment rights is reviewed de novo. See United States v.
    Whaley, 
    13 F.3d 963
    , 968–69 (6th Cir. 1994) (“While we
    accept, unless clearly erroneous, the facts that the district court
    found, whether those facts together constitute an ‘initiation’
    under Edwards is a legal question we review de novo.”); cf.
    
    Yunis, 859 F.2d at 958
    (waiver of Fifth and Sixth Amendment
    rights).
    D.
    1.
    Because the government does not contest the issue, we
    assume without deciding that both the Fifth Amendment
    privilege against self-incrimination and the Miranda and
    Edwards doctrines govern the admissibility at trial of
    statements obtained by U.S. authorities from nonresident
    aliens who first assert their right to counsel while held in
    foreign custody.
    Ordinarily a suspect can waive his Miranda rights. See
    Maryland v. Shatzer, 
    559 U.S. 98
    , 104 (2010). But special
    protections apply once the suspect has invoked his
    constitutional right to counsel during custodial interrogation.
    When that happens, the Supreme Court has interposed a
    “second layer of prophylaxis.” 
    Id. (quoting McNeil
    v.
    Wisconsin, 
    501 U.S. 171
    , 176 (1991)). “[W]hen an accused
    has invoked his right to have counsel present during custodial
    interrogation, a valid waiver of that right cannot be established
    by showing only that he responded to further police-initiated
    custodial interrogation.” 
    Edwards, 451 U.S. at 484
    . That is
    because, “if a suspect believes that he is not capable of
    undergoing [custodial] questioning without advice of counsel,
    then it is presumed that any subsequent waiver . . . is itself the
    product of the ‘inherently compelling pressures’ [of custodial
    84
    interrogation] and not the purely voluntary choice of the
    suspect.” 
    Roberson, 486 U.S. at 681
    (quoting 
    Miranda, 384 U.S. at 467
    ); see also Montejo v. Louisiana, 
    556 U.S. 778
    ,
    794–95 (2009) (Edwards prevents police from “badgering” a
    defendant into waiving his previously asserted “right to have
    counsel during custodial interrogation—which right happens
    to be guaranteed (once the adversary judicial process has
    begun) by [both the Fifth and Sixth Amendments.]”).
    Consequently, it is only when the subsequent questioning is “at
    the suspect’s own instigation” that a valid waiver of Miranda
    rights will be found. 
    Shatzer, 559 U.S. at 104
    (internal
    quotation marks omitted).
    The government does not dispute that Straker exercised
    his right to counsel during the January 9, 2006 interrogation
    when he said that he wanted to speak to his lawyer. As the
    case comes to us, the government has also conceded that
    Straker was in Miranda custody at the time of that
    interrogation, and that there was no break in that custody
    during the eighteen months leading up to the FBI’s July 29,
    2007 interrogation. Gov’t Br. 191 n.96. We thus assume
    that the “judicially prescribed prophylaxis” of Edwards applies
    on these facts, 
    Shatzer, 559 U.S. at 105
    , without needing to
    decide whether and for how long Edwards applies while the
    accused is held in continuing foreign custody. In addition,
    because Straker does not argue that any purported initiation of
    conversation with the FBI lapsed during the year and a half
    between when he left his phone message for Agent Freeman
    and the interrogation at which he confessed, we need not
    decide if an officer must immediately act upon, or whether a
    waiver of Miranda rights must follow closely on the heels of, a
    suspect’s “initiation” of conversation with the authorities.
    Once Straker invoked his right to counsel during an
    interrogation to which Miranda has been stipulated to apply,
    85
    the FBI could not “subject [him] to further interrogation . . .
    unless [Straker] himself initiate[d] further communication,
    exchanges, or conversations with the[m].” 
    Edwards, 451 U.S. at 484
    –85. The parties agree that the plurality opinion in
    Bradshaw governs our inquiry into whether Straker’s
    telephone call to Agent Freeman initiated discussion with the
    FBI. Straker Suppl. Br. 1 (“[T]he plurality opinion in Oregon
    v. Bradshaw does provide a framework for evaluating whether
    Straker evinced a willingness to engage in a generalized
    discussion.”); Gov’t Suppl. Br. 7–11 (arguing that the
    Bradshaw plurality controls the initiation question).
    Under the Bradshaw framework, whether Straker’s
    telephone message to Agent Freeman constitutes initiation
    turns on whether the statement “evinced a willingness and a
    desire for a generalized discussion about the investigation.”
    
    Bradshaw, 462 U.S. at 1045
    –46. On the other hand, if
    Straker’s statement concerned “routine incidents of the
    custodial relationship”—“such as a request for a drink of water
    or a request to use a telephone,” that would not suffice and the
    Edwards bar on further questioning would remain intact. 
    Id. at 1045.
    It bears noting that the “initiation” inquiry is distinct from,
    and antecedent to, the question whether “subsequent events
    indicated a waiver of the Fifth Amendment right to have
    counsel present during the interrogation.” 
    Bradshaw, 462 U.S. at 1044
    . The latter inquiry is rigorous, requiring that we
    determine whether the government has proven that the
    “purported waiver was knowing and intelligent,” 
    id. at 1046,
    and “indulge in every reasonable presumption against waiver,”
    Brewer v. Williams, 
    430 U.S. 387
    , 404 (1977). In conducting
    the initiation inquiry, by contrast, we ask not what the suspect
    intended to do, but what intention the police officer “could
    reasonably      have      ...    interpreted”     the      suspect’s
    86
    statements—even if “ambiguous”—to “evince[],” without any
    legal presumption one way or the other. 
    Bradshaw, 462 U.S. at 1045
    –46.
    Taken together and viewed from the perspective of a
    reasonable officer, both the content and the context of Straker’s
    message “evinced a willingness and a desire” to reinitiate
    communications with the FBI concerning the criminal
    investigation. Bradshaw, 
    462 U.S. 1045
    –46. Straker, in
    fact, does not dispute that he called the number Agent Freeman
    had given him and left a voicemail message “asking Freeman
    to call him back.” Straker, 
    596 F. Supp. 2d
    at 89, 94.
    The government concedes that statement, considered in
    isolation, would not evince a desire to resume discussion of the
    investigation because it gives no specific indication of what
    Straker wished to discuss. Oral Arg. Tr. 131. We agree.
    But that statement does not stand alone. When considered in
    context and on this record, an officer could reasonably have
    understood Straker’s statement as inviting renewed discussion
    about the investigation.           Like the statement in
    Bradshaw—“Well, what is going to happen to me
    now?”—Straker’s message asking Freeman “to call him back,”
    Straker, 
    596 F. Supp. 2d
    at 89, “could reasonably have been
    interpreted by the officer as relating generally to the
    investigation,” 
    Bradshaw, 462 U.S. at 1046
    .
    First, Straker left the voicemail just a couple weeks after
    specifically advising Agent Clauss and Agent Freeman that,
    once he spoke with his lawyer, he “would be willing to speak
    to” them. J.A. 2259. Indeed, as the district court explained,
    “[t]he record is compelling that Straker made his request for
    counsel subject to an understanding that he would have an
    opportunity to contact the FBI later if he so wished.” Straker,
    
    596 F. Supp. 2d
    at 93. Viewed in that context, Straker’s
    87
    voluntary decision to call Agent Freeman a couple weeks later
    and leave a message asking Freeman to call him back could
    reasonably have been viewed as Straker following up where he
    left off with the FBI and initiating discussion of the
    investigation. See United States v. Hart, 
    619 F.2d 325
    , 326–
    27 (4th Cir. 1980) (per curiam) (concluding that defendant,
    after having twice invoked his right to counsel, reinitiated
    communication with law enforcement when “he telephoned
    the Washington Field Office stating that he wished to speak
    with the arresting agent”).
    Second, when during the interview Straker “indicated that
    ‘after having access to his attorney, he would be willing to
    speak to the agents,’” Straker, 
    596 F. Supp. 2d
    at 87, Agent
    Clauss invited Straker, after talking with his attorney, to
    contact the FBI if he still wanted to talk. Agent Freeman then
    provided Straker a business card with a designated number to
    call “if he wanted to make an attempt to contact” them. J.A.
    2191. And that designated number is the one Straker used to
    make his call.
    Third, nothing about the context or content of Straker’s
    message suggests that it was “a necessary inquiry arising out of
    the incidents of the custodial relationship.” 
    Bradshaw, 462 U.S. at 1046
    . Because Straker was not in actual or even
    apparent U.S. custody during the weeks between the initial
    interrogation and Straker’s message, there is no plausible basis
    for concluding—and Straker does not even argue—that he was
    calling Agent Freeman to discuss his conditions of
    confinement or the future procedural course for him while in
    Trinidadian custody, neither of which the FBI could control.
    Moreover, when Straker called Agent Freeman, he had not yet
    been indicted in the United States, so a reasonable officer
    would not have interpreted Straker’s call as inquiring about
    extradition or other aspects of criminal processing. Nor
    88
    would it have made sense for Straker to call Agent Freeman to
    request a drink of water, see 
    Bradshaw, 462 U.S. at 1045
    ,
    discuss “procedural matters” like “bond, scheduling, and a
    preliminary hearing,” Haynes v. State, 
    934 So. 2d 983
    , 989–91
    (Miss. 2006), or talk about anything else relating to the routine
    aspects of being in police custody.
    Straker nevertheless argues (Suppl. Br. 1) that there was
    another possible reason for his call: an effort to seek the FBI’s
    aid in locating his father. He points to a conversation he had
    with Agent Clauss during the January 9th interrogation in
    which he stated that Clauss resembled his father and suggested
    that the FBI might be able to help find his father in the United
    States. Straker Suppl. Br. 8–11; see also Straker, 
    596 F. Supp. 2d
    at 86. But the district court found that the comment was
    understood at the time to be a “joke[],” Straker, 
    596 F. Supp. 2d
    at 86, part of what Agent Clauss described as a “jovial”
    story, not a serious request, J.A. 2187. In any event, the
    question is not whether the initiation of discussion about the
    investigation is the only possible explanation for Straker’s
    reaching out. The relevant question is whether a reasonable
    officer could have understood Straker’s telephone call as
    indicating that Straker wanted to talk generally about the
    investigation. Although we, like the district court, think this is
    a “close call,” Straker, 
    596 F. Supp. 2d
    at 94, considering the
    content and all the surrounding circumstances, the FBI agents
    could reasonably have interpreted Straker’s voluntary reaching
    out and the message he left as “evinc[ing] a willingness and a
    desire for a generalized discussion about the investigation”
    itself. 
    Bradshaw, 462 U.S. at 1045
    –46.
    2.
    While Straker initiated conversation with the FBI relating
    to the investigation, the burden remains on the government to
    89
    prove that, under the totality of the circumstances, Straker
    subsequently waived his Miranda rights voluntarily,
    knowingly, and intelligently. See 
    Bradshaw, 462 U.S. at 1044
    . Reviewing the district court’s finding of waiver de
    novo, see 
    Yunis, 859 F.2d at 958
    , we affirm.
    To begin with, the record amply demonstrates that Straker
    understood his rights and the significance of any waiver
    decision. During Straker’s January 2006 interview, the FBI
    advised him of his Miranda rights, and he “demonstrated that
    he understood his rights well enough to make an initial
    decision declining to speak about the investigation until he had
    consulted with his Trinidad[ian] attorney.” Straker, 596 F.
    Supp. 2d at 95. Agent Clauss advised Straker of his Miranda
    rights a second time during extradition, using the FBI’s
    standard advice-of-rights form. And Straker, having had
    eighteen months to consult with his attorney, signed the
    waiver-of-rights statement. 
    Id. There is
    no indication that
    Straker was coerced into signing that statement. Nor was
    there any opportunity for the FBI to badger Straker into doing
    so, since no one from the FBI even contacted Straker for the
    year and a half preceding his extradition. See 
    id. at 96–99.
    Straker does not challenge any of the district court’s
    factual findings and points to no facts undermining the
    reliability of the waiver, resting his argument entirely on the
    “presumption against waiver of constitutional rights.” Def.
    Br. 140. But the presumption is just that—a presumption that
    can be, and in this case was, overcome.
    3.
    Straker footnotes an argument that, because his Sixth
    Amendment right to counsel attached after the message he left
    for Agent Freeman, that message could not have constituted a
    90
    waiver of that right. Def. Br. 141 n.60. Maybe. But that is
    beside the point. We agree with the district court that the
    Miranda warnings provided by the FBI during Straker’s
    extradition—after his Sixth Amendment right to counsel had
    attached—“sufficiently apprised Straker of ‘the nature of his
    Sixth Amendment rights, and of the consequences of
    abandoning those rights, so that his waiver on [that] basis will
    be considered a knowing and intelligent one.’” Straker, 
    596 F. Supp. 2d
    at 101 (quoting 
    Patterson, 487 U.S. at 296
    )
    (alteration in original). Thus, when Straker validly waived his
    Fifth Amendment rights after being given Miranda warnings,
    he waived his Sixth Amendment right to counsel as well. See
    
    Patterson, 487 U.S. at 300
    (“So long as the accused is made
    aware of the dangers and disadvantages of self-representation
    during postindictment questioning, by use of the Miranda
    warnings, his waiver of his Sixth Amendment right to counsel
    at such questioning is knowing and intelligent.”) (internal
    quotation marks omitted); see also 
    Montejo, 556 U.S. at 795
    (“[T]he right under both [the Fifth and Sixth Amendments] is
    waived using the same procedure.”).
    VIII.
    Denial of Defendants’ Motions for Severance
    Defendants Sealey and Straker challenge the district
    court’s refusal to sever the charges against them, arguing that
    the evidence presented against their codefendants at trial
    compromised the jury’s ability to make an individualized
    determination of guilt as to each of them. 19
    19
    In footnotes, additional defendants seek to join Sealey and
    Straker’s severance arguments. The same legal standards apply to
    each defendant’s motion to sever, but the fact-specific nature of the
    91
    “Joint trials play a vital role in the criminal justice
    system,” promoting efficiency and avoiding the “scandal and
    inequity of inconsistent verdicts.” Zafiro v. United States,
    
    506 U.S. 534
    , 537 (1993) (internal quotation marks omitted).
    For these reasons, and to “‘conserve the time of courts,
    prosecutors, witnesses, and jurors,’” we have urged district
    courts to grant severance “sparingly.” United States v. Celis,
    
    608 F.3d 818
    , 844 (D.C. Cir. 2010) (quoting United States v.
    Mardian, 
    546 F.2d 973
    , 979 (D.C. Cir. 1976)). Severance is
    warranted where there is a “serious risk that a joint trial would
    compromise a specific trial right of one of the defendants, or
    prevent the jury from making a reliable judgment about guilt or
    innocence.” 
    Zafiro, 506 U.S. at 539
    . Where joinder of
    defendants in an indictment or trial “appears to prejudice a
    defendant,” district courts should, in their discretion, order
    separate trials. Fed. R. Crim. P. 14(a). Severance is not
    required, however, “when there is substantial and independent
    evidence of each [defendant’s] significant involvement in the
    conspiracy.” United States v. Moore, 
    651 F.3d 30
    , 96 (D.C.
    Cir. 2011) (alteration in original) (internal quotation marks
    omitted), aff’d on other grounds sub nom., Smith v. United
    States, 
    133 S. Ct. 714
    (2013). Moreover, “[a]bsent a dramatic
    disparity of evidence” against defendants whose trials might be
    joined, “any prejudice caused by joinder is best dealt with by
    inquiry renders adoption by reference inappropriate. See supra note
    5; United States v. Solis, 
    299 F.3d 420
    , 441 n.46 (5th Cir. 2002)
    (“[S]everance issues are fact-specific, requiring a showing of
    ‘specific compelling prejudice,’ and so cannot be [] adopted by
    reference.”) (internal citation omitted). Only Sealey and Straker
    have attempted to apply the law, as they see it, to the evidence that
    pertains to them. We decline to determine in the first instance,
    without defendant-specific briefing, how the law applies to their
    codefendants as well. See generally Carducci v. Regan, 
    714 F.2d 171
    , 177 (D.C. Cir. 1983).

    Cir. 1980); see 
    Zafiro, 506 U.S. at 539
    . “We review the denial
    of a motion to sever for abuse of discretion, which we will not
    find if the jury could reasonably compartmentalize the
    evidence introduced against each individual defendant.”
    
    Celis, 608 F.3d at 844
    (internal quotation marks omitted).
    Sealey argues that he suffered prejudice from the joint trial
    because he “participated in a kidnapping” but “had no part in”
    the victim’s death, creating a risk that the evidence against
    Sealey’s codefendants would “rub off” on him. Def. Br. 122–
    23. In addition, both Sealey and Straker contend that they
    were prejudiced by the introduction of evidence of past hostage
    takings, discussed supra Section III, in which they did not
    participate.    The district court addressed and rejected
    defendants’ “spillover prejudice” arguments, concluding that
    the substantial and independent evidence against Sealey and
    Straker enabled the jury to reasonably compartmentalize the
    evidence of guilt against each of them from the rest of the
    evidence at trial. 
    Clarke, 767 F. Supp. 2d at 26
    .
    Defendants assert that the district court misapplied the law
    governing severance. We see no legal error. The district
    court not only measured the strength of the evidence against
    Sealey and Straker, but also the degree to which it was
    independent of the evidence against their codefendants. Both
    assessments were critical to determining whether the evidence
    against them was sufficiently “substantial” and “independent.”
    See, e.g., 
    Celis, 608 F.3d at 844
    –45.
    The evidence the government introduced of Sealey and
    Straker’s guilt was both substantial and independent. A
    reasonable jury could have found that the government’s
    evidence established their culpability and role in the
    93
    conspiracy. As the district court determined, Sealey’s
    detailed confession to the Trinidadian police, a separate
    confession to the FBI, and trial testimony from two
    co-conspirators overwhelmingly supported the jury’s
    conclusion that he was one of the conspirators who abducted
    Maharaj at the Samaan Tree Bar.               Sealey, with his
    codefendants, participated in the getaway as well, transporting
    Maharaj to the cocoa fields where he was initially held. While
    the evidence did not show him to have participated in every
    stage, it sufficed to support the jury’s finding that Sealey
    played a significant role in the hostage taking.
    Straker, too, confessed to his role in the hostage taking,
    and his confession was supplemented by his own trial
    testimony and the trial testimony of three co-conspirators.
    Indeed, one of Straker’s co-conspirators testified that the
    kidnapping was Straker’s idea. The evidence of Straker’s
    guilt, like that of Sealey’s, was substantial and independent
    from the evidence introduced against their codefendants, such
    that the jury could readily compartmentalize the evidence
    against each of them from the rest of the evidence at trial.
    The presentation of other-crimes evidence also did not
    prejudice Sealey and Straker. That evidence did not concern
    them, and, as we have already discussed, the district court gave
    adequate limiting jury instructions in connection with the
    presentation of that evidence. Sealey and Straker fail to
    identify any defect in the manner in which the other-crimes
    evidence was presented that might have led the jury
    erroneously to apply it against them.
    Straker’s reliance on our decision in United States v.
    Sampol, 
    636 F.2d 621
    (D.C. Cir. 1980) (per curiam), is not
    persuasive. In that case, Ignacio Novo was charged alongside
    members of an underlying conspiracy to assassinate the
    94
    Chilean Ambassador to the United States. The charges
    against Novo, however, were limited to making false
    statements to a grand jury and misprision of a felony. We held
    that the joint trial prejudiced Novo because the “grossly
    disparate” charges and intermingled presentation of evidence
    at trial created a situation in which “[t]here was never [a] clear
    distinction between the different defendants and the evidence
    against each of them.” 20 
    Id. at 6
    45, 647. Disparate charges
    also led the Sixth Circuit to require severance in United States
    v. Davidson, 
    936 F.2d 856
    , 861 (6th Cir. 1991). There were
    no such defects here. Sealey and Straker were instrumental
    participants in the conspiracy to take Maharaj hostage, they
    were charged with the same offenses as their codefendants, and
    the evidence presented at trial was not intermingled so as to
    create the false impression that Sealey or Straker were
    involved in any of the uncharged conduct.
    If there were any such prejudice, moreover, it would have
    been cured by the district court’s carefully selected and crafted
    jury instructions. The judge gave well-timed cautions to
    jurors at key points: on the first day of trial; before the
    introduction of the other-crimes evidence; a final “Other
    Crimes Evidence” instruction at the close of trial; and a final
    instruction reiterating that “each defendant is entitled to have
    the issue of his guilt as to each of the crimes for which he is on
    trial determined from his own conduct and from the evidence
    that applies to him as if he were being tried alone.” J.A. 1929
    20
    A further distinguishing feature between this case and Sampol is
    that our holding there expressly rested on “a cumulation of
    circumstances” that prejudiced defendant Novo: confusion of
    charges, grossly disparate charges, and Novo’s inability to present a
    full defense and cross-examine witnesses whose testimony implied
    that he participated in additional crimes for which he was not
    charged. 
    Sampol, 636 F.3d at 651
    .
    95
    (emphasis omitted); see also J.A. 1931 (Instruction 2.55); J.A.
    3026–27, 3205–07.
    It is in the nature of a conspiracy prosecution that the
    evidence against each member will differ, and that the
    members of the conspiracy will have different roles. That
    some co-conspirators will be more central than others does not
    render joint trial inappropriate as long as the jury can
    reasonably compartmentalize the substantial and independent
    evidence against each defendant. See, e.g., 
    Celis, 608 F.3d at 844
    –45; United States v. Mejia, 
    448 F.3d 436
    , 446–47 (D.C.
    Cir. 2006). We find no abuse of discretion here, where the
    government presented substantial and independent evidence
    against Sealey and Straker establishing their significant roles in
    the conspiracy, and the district court sought to cure any
    potential prejudice with careful instructions to the jury.
    IX.
    Closing Argument
    Defendants Sealey and Nixon object to the government’s
    rebuttal closing argument, claiming that the prosecution
    advanced an alternative factual theory of guilt for Sealey and
    Nixon that was inconsistent with the evidence at trial and the
    government’s initial closing argument. 21         We review
    21
    Defendants De Four and Straker purport to adopt by reference
    Sealey and Nixon’s objection to the government’s rebuttal closing.
    Def. Br. 130 n.57. As discussed supra note 5, not every argument is
    an appropriate candidate for adoption by reference. Sealey and
    Nixon make a fact-specific objection to the government’s purported
    shift in theory of their guilt during closing argument. De Four and
    Straker do not explain how that objection could apply to them as
    well, and we refrain from guessing.
    96
    allegedly improper prosecutorial argument for “substantial
    prejudice,” and the district court’s denial of defendants’
    motions for new trials based on that objection for abuse of
    discretion. 
    Moore, 651 F.3d at 50
    .
    Sealey and Nixon contend that the government’s evidence
    and initial closing argument were aimed at proving that Sealey
    entered the Samaan Tree Bar, grabbed Maharaj, and dragged
    him outside to the waiting Nixon. They characterize the
    government’s rebuttal closing argument as advancing the
    contrasting theory that it was Nixon who entered the bar, not
    Sealey. After comprehensively reviewing the evidence at trial
    and the government’s two closing arguments, the district court
    found defendants’ characterization of the proceedings “wholly
    lacking in merit” and “simply not borne out by the record.”
    
    Clarke, 767 F. Supp. 2d at 91
    , 94. We do as well.
    The evidence at trial included testimony that two men
    entered the bar and “grabbed” Maharaj, J.A. 2895–96, and that
    Nixon exited first, followed by Sealey, who was “pulling
    [Maharaj] out of the bar,” J.A. 3061. Sealey’s statement to the
    Trinidadian police also indicated that he and another man both
    “went inside the bar,” and that both he and another man
    “end[ed] up sticking the man up.” J.A. 4395. Consistent
    with that evidence, the prosecutor argued in closing that both
    Sealey and Nixon entered the bar. J.A. 4966. Nothing in the
    government’s evidence at trial, or in its initial closing,
    suggested that Sealey alone entered the Samaan Tree Bar.
    In his closing argument, it was Sealey who argued that he
    was not the man who “went in and grabbed Mr. Maharaj”
    because some eyewitnesses described a muscular gunman
    wearing a “rasta hat,” and Sealey was neither muscular nor was
    there any evidence that he wore such a hat. J.A. 5094–97.
    Sealey’s argument implied that only one abductor entered the
    97
    bar, and that it was not him. In response, the prosecutor
    argued that the eyewitness testimony was not inconsistent with
    the government’s theory that both Sealey and Nixon entered
    the bar, and that it was Nixon who was muscular and wearing a
    “rasta hat.” J.A. 5194–95.
    We see no necessary inconsistency between the
    prosecutor’s rebuttal and the initial closing arguments, nor
    with the evidence at trial. The government argued throughout
    that Sealey and Nixon entered the Samaan Tree Bar and
    abducted Maharaj. The evidence supported that theory.
    Granted, two eyewitnesses testified that only one gunman
    entered, which presented Sealey and Nixon each with an
    opportunity to claim he was not involved. See Clarke, 767 F.
    Supp. 2d at 92. But, as the district court concluded, the fact
    that eyewitnesses may “have inconsistent recollections on
    some points is no surprise.” 
    Id. The jury
    could reasonably
    have credited testimony describing Nixon’s actions without
    also crediting the witnesses’ recollection that Nixon entered
    the bar alone. As the government consistently argued, other
    evidence supported the conclusion that both Sealey and Nixon
    abducted Maharaj.
    Defendants have failed to show the “substantial prejudice”
    from a prosecutorial argument that is required to warrant a new
    trial.    
    Moore, 651 F.3d at 50
    .           As just noted, the
    government’s evidence and closing arguments were consistent.
    We find no error—much less an abuse of discretion—in the
    district court’s denial of Sealey and Nixon’s motions for new
    trials based on the prosecutor’s rebuttal closing argument.
    98
    X.
    Due Process Claim
    Straker argues that he was deprived of his Fifth
    Amendment right to due process because he was unable to
    obtain “Blue Files” from Trinidadian authorities, which he
    contends are law enforcement records documenting charges,
    arrests, or convictions of persons in Trinidad, including the
    cooperating witnesses. 
    Clarke, 767 F. Supp. 2d at 70
    –71.
    Straker argues that the information might have assisted his
    impeachment of witnesses who testified against him. 
    Id. at 70–71.
    22
    The district court denied Straker’s motion for a new trial,
    finding no due process violation. We agree completely with
    the district court’s analysis and affirm. We review the denial
    of a motion for a new trial for an abuse of discretion, see
    United States v. Becton, 
    601 F.3d 588
    , 594 (D.C. Cir. 2010),
    though we review de novo the constitutional question whether
    any limitation on Straker’s defense violated his Fifth
    Amendment right to due process, see United States v. Lathern,
    
    488 F.3d 1043
    , 1045–46 (D.C. Cir. 2007).
    The “right to present a defense is a fundamental element of
    due process of law, and the preclusion of all inquiry by the
    defense on a particular aspect of the case violates that right.”
    United States v. Stewart, 
    104 F.3d 1377
    , 1384 (D.C. Cir. 1997)
    (citations and internal quotation marks omitted). Straker,
    however, has failed to demonstrate any material impairment of
    his defense.
    22
    Clarke, De Four, and Sealey adopt this claim. Def. Br. 141 n.61.
    Our analysis applies equally to those defendants.
    99
    First, Straker has not demonstrated that the “Blue Files” he
    sought even exist, and the government’s inquiries to
    Trinidadian officials suggest that they do not. Nor does
    Straker explain what information the Blue Files would have
    contained that he did not already receive in the arrest and
    conviction records provided to him by the prosecution. There
    thus is no evidence that the district court or prosecution
    impeded any viable avenue of inquiry.
    Second, Straker enjoyed a robust opportunity to
    cross-examine the cooperating witnesses and to attack their
    credibility based on the arrest and conviction records that the
    U.S. government disclosed. Straker makes no proffer that the
    Blue Files would have allowed him to pursue any line of
    impeachment that he did not already cover. On top of that,
    Straker had ample opportunity, even without the arrest records,
    to impeach the cooperating witnesses with their plea
    agreements and quests for leniency at sentencing. See 
    Clarke, 767 F. Supp. 2d at 67
    –71 (chronicling defense counsel’s
    “extensive” impeachment efforts).        That alone answers
    Straker’s claim that he was precluded from “all inquiry” into
    the witnesses’ credibility. See 
    Stewart, 104 F.3d at 1384
    (court did not “preclude all defense inquiry” into issue by
    “rul[ing] out repetitive questioning and further questioning of
    the expert witness”).
    Third, the Due Process Clause governs the conduct of the
    court and the prosecution, not of foreign governments’
    responses to letters rogatory. Straker, however, identifies
    nothing that either the court or prosecution did wrong. Quite
    the opposite, Straker acknowledges that the district court “was
    completely accommodating” in granting to defense counsel
    whatever investigative resources were needed, authorizing the
    issuance of letters rogatory seeking documents from Trinidad
    100
    through diplomatic channels, and permitting defense counsel
    to travel to Trinidad several times. Def. Br. 141 n.62. In
    addition, the U.S. government repeatedly inquired about the
    so-called “Blue Files” with “knowledgeable individuals in the
    Trinidadian government, and was informed” that such files did
    not exist. 
    Clarke, 767 F. Supp. 2d at 71
    .
    In sum, because Straker did not establish that the Blue
    Files even exist, that they contain any impeachment
    information materially different from what he already had and
    used, or that the district court or prosecution did anything at all
    to impair his presentation of a defense, no due process
    violation occurred, and the district court’s denial of the motion
    for a new trial was well within its discretion.
    XI.
    Admissibility of Expert Fingerprint Testimony
    Straker’s challenge to the admission of expert fingerprint
    testimony fares no better. 23
    To demonstrate Straker’s consciousness of guilt, the
    government introduced as evidence a note with an
    accompanying news article that Straker sent Percival in which
    Straker asked Percival not to testify. 
    Clarke, 767 F. Supp. 2d at 23
    . The news article suggested “that the U.S. Attorney’s
    Office did not have the power to ensure that a court would
    grant [Percival] leniency for his cooperation.” 
    Id. The note
    23
    De Four purports to join Straker’s argument. Def. Br. 145 n.65.
    De Four did not join Straker’s motion below, so we would review his
    claim for plain error only. Because we find no error at all, De
    Four’s claim necessarily fails.
    101
    was linked to Straker through the testimony of FBI fingerprint
    examiner Dawn Schilens. 
    Id. At the
    outset, Schilens testified “on her qualifications as
    an expert in the field of fingerprint identification and analysis,
    which included employment as a physical scientist/forensic
    examiner in the latent print operation unit of the FBI, her
    certification following an 18-month training program, and her
    experience in having conducted over 140,000 fingerprint
    comparisons.” 
    Clarke, 767 F. Supp. 2d at 73
    . When the
    government offered Schilens as an expert in the field of
    fingerprint identification, Straker did not object. 
    Id. After she
    testified, however, Straker moved to strike her testimony
    under Daubert v. Merrell Dow Pharmaceuticals, Inc., 
    509 U.S. 579
    (1993), arguing that Schilens failed “to articulate an error
    rate” in the fingerprint methodology she used. Clarke, 767 F.
    Supp. 2d at 73.
    The district court denied the motion to strike and the
    subsequent motion for a new trial, finding that “Schilens did
    present testimony on the error rate.” 
    Clarke, 767 F. Supp. 2d at 73
    . Finding no abuse of discretion, see United States v.
    Day, 
    524 F.3d 1361
    , 1369 (D.C. Cir. 2008), we affirm.
    The admission of expert testimony is governed by Federal
    Rule of Evidence 702. In Daubert, the Supreme Court held
    that Rule 702 requires a district court, before admitting expert
    testimony, to determine whether the “reasoning or
    methodology underlying the testimony is scientifically valid
    and . . . whether that reasoning or methodology properly can be
    applied to the facts in 
    issue,” 509 U.S. at 592
    –93. Among the
    factors Daubert instructed courts to consider in determining
    the reliability “of a particular scientific technique” is the
    “known or potential rate of 
    error.” 509 U.S. at 594
    .
    102
    Here, Schilens “testified that there are two different types
    of error—the error rate in the methodology and human error.”
    
    Clarke, 767 F. Supp. 2d at 73
    (citations omitted). She further
    testified that her “‘methodology, ACE–V, does not have an
    inherent rate of error’—that is, ‘[t]here is a zero rate of error in
    the methodology.’” 
    Id. (citations omitted)
    (alteration in
    original). But Schilens did not articulate the rate of human
    error, though she acknowledged the potential for such error.
    See 
    id. Straker contends
    that Schilens’s failure to articulate the
    rate of human error in the ACE-V methodology rendered her
    testimony based on that methodology inadmissible. That is
    wrong. The factors listed in Daubert “do not constitute a
    definitive checklist or test,” but rather “may or may not be
    pertinent in assessing reliability, depending on the nature of the
    issue, the expert’s particular expertise, and the subject of [the]
    testimony.” Kumho Tire Co. v. Carmichael, 
    526 U.S. 137
    ,
    150 (1999) (internal quotation marks and alteration omitted).
    No specific inquiry is demanded of the trial court. See 
    id. at 152.
    The reliability of Schilens’s fingerprint methodology was
    “properly taken for granted.” Kumho 
    Tire, 526 U.S. at 152
    .
    “Numerous courts have found expert testimony on fingerprint
    identification based on the ACE-V method to be sufficiently
    reliable under Daubert,” and “against such a backdrop, it is
    difficult to discern,” without more, “any abuse of discretion
    when the district court decides to admit expert testimony that
    relies on the ACE-V method.” United States v. Peña, 
    586 F.3d 105
    , 110–11 (1st Cir. 2009) (internal quotation marks
    omitted) (collecting cases).
    Beyond that, Straker has identified no harm resulting from
    the admission of Schilens’s testimony. Evidence at trial
    103
    showed that Straker played a pivotal role in the conspiracy
    from its inception, and the testimony of the cooperating
    witnesses established that he played a central role in plotting
    the crime’s execution. That testimony, coupled with Straker’s
    confession, constituted “devastating evidence” of Straker’s
    guilt. United States v. Smith, 
    640 F.3d 358
    , 368 (D.C. Cir.
    2011). There is no reasonable possibility that the admission
    of Schilens’s testimony with its omitted human error rate had
    any “discernible effect on the jury’s verdict.” 
    Id. XII. For
    the foregoing reasons, we affirm defendants’
    convictions and the judgment of the district court.
    So ordered.
