    OPINION
    GIBSON, Circuit Judge:
    Gwaine Lavon Collins was indicted, along with four other
    individuals, for six counts of conspiracy to possess with intent
    to distribute and to distribute methamphetamine, 
    21 U.S.C. §§ 846
     and 841(a)(1), and possession of methamphetamine,
    
    21 U.S.C. § 844
    . He was tried on the conspiracy count and on
    two counts of distribution: first, for distributing 919 grams of
    methamphetamine on August 10, 2004, and second, for dis-
    tributing 3,124 kilograms of methamphetamine on August 17,
    2004. Collins was convicted of each count after a trial by jury.
    At trial, Collins admitted to his participation in the drug sales,
    but he argued that he was entrapped to perform those sales by
    government informant James Kim. On appeal, he raises three
    arguments: (1) the district erred in refusing to require the gov-
    ernment to state its reason for striking the sole remaining
    African-American from the potential jury, Batson v. Ken-
    tucky, 
    476 U.S. 79
     (1986); (2) the government suppressed an
    audiotape recording of a conversation between Kim and
    another drug dealer in contravention of Collins’s constitu-
    tional rights under the compulsory process clause, Brady v.
    70                 UNITED STATES v. COLLINS
    Maryland, 
    373 U.S. 83
     (1963), and the confrontation clause;
    and (3) the district court erred when it refused to require the
    government to accept a subpoena for confidential informant
    Danny Yim, a principal witness in the uncharged misconduct
    of the defendant that Collins argued supported his entrapment
    defense. We affirm in all respects except the Batson issue, on
    which we reverse and remand for an evidentiary hearing.
    We need not recount Collins’s participation in the two
    August methamphetamine transactions because Collins does
    not dispute his involvement in those sales. Rather, we set
    forth the facts alleged at trial that are necessary to understand
    Collins’s entrapment defense, which is largely drawn from
    Collins’s own testimony.
    Collins and Kim befriended one another while incarcerated
    in the Metropolitan Detention Center in Los Angeles, Califor-
    nia. While in prison, Kim and Collins discussed Kim helping
    Collins become involved with Kim’s import/export business
    of (non-narcotic) goods. According to Collins, when he was
    released he soon contacted Kim, and they proceeded together
    on several potential business ventures, none of which appears
    to have been executed. Unbeknownst to Collins, Kim was
    already preparing to work as a government informant as far
    back as their time in prison together.
    The crux of Collins’s entrapment claim is that, according
    to Collins, in late June 2004, Kim became distraught because
    he needed a lot of money to pay off the escrow on his restau-
    rant, which was subject to a lien. According to Collins, Kim
    asked him to find some drugs they could sell. Collins claimed
    Kim was agitated and intoxicated when he told him about the
    restaurant problem. Despite Kim’s predicament, Collins
    claimed that he initially refused because he had no desire to
    get back into the drug business. But, Collins testified, Kim
    repeatedly called him, with some new “drama,” and continued
    to ask him about selling drugs. Collins testified that he tried
    to convince Kim that they could make the money Kim needed
    UNITED STATES v. COLLINS                  71
    through their other ventures and even offered to give Kim his
    share of the profits from a DVD import deal they had previ-
    ously discussed. Kim, however, was unresponsive to any of
    Collins’s inquires regarding the other business. Finally, Col-
    lins relented and helped Kim procure methamphetamine in
    July, although Collins claimed that he received no money
    from that deal, but rather did it solely to help the distraught
    Kim. After the uncharged deal in July, Collins claimed that he
    initially refused to be involved further with drugs. Collins
    relented again and participated in the two August deals, which
    formed the basis for his convictions. He admitted that he
    intended to invest his own money in a pound of methamphet-
    amine so he could sell it. Kim testified that Collins never said
    he did not want to do the drug deals, but that “he always
    wanted to do it.”

    [1] “[T]he Equal Protection Clause forbids the prosecutor
    to challenge potential jurors solely on account of their race or
    on the assumption that black jurors as a group will be unable
    impartially to consider the State’s case against a black defen-
    dant.” Batson, 
    476 U.S. at 89
    . When a defendant alleges a
    Batson violation, a three-part burden shifting test is used to
    determine if the potential juror was challenged on the basis of
    impermissible discrimination. At the outset, the defendant
    must make a prima facie showing that the challenge was
    based on an impermissible ground, such as race. 
    Id. at 96

    “This is a burden of production, not a burden of persuasion.”

    accord Johnson v. California, 
    545 U.S. 162
    , 170-71 (2005).
    “Second, if the trial court finds the defendant has made a
    prima facie case of discrimination, the burden then shifts to
    the prosecution to offer a race-neutral reason for the challenge
    that relates to the case.” Green,

    ; accord Bat-
    son,

    . “Third, if the prosecutor offers a race-
    neutral explanation, the trial court must decide whether the
    defendant has proved the prosecutor’s motive for the strike
    72                  UNITED STATES v. COLLINS
    was purposeful racial discrimination.” Green, 
    532 F.3d at 1030
    ; accord Johnson, 
    545 U.S. at 168
    ; Batson, 
    476 U.S. at 98
    .
    [2] Collins objected when the prosecution struck Juror No.
    9, the only remaining African-American member on the
    panel, and argued that she was struck on account of her race.
    The district court found that Collins failed to make a prima
    facie showing of discrimination and did not require the gov-
    ernment to explain why it peremptorily removed Juror No. 9.
    We generally review a district court’s Batson determination
    for clear error because of the intrinsically factual nature of the
    claim. Tolbert v. Page, 
    182 F.3d 677
    , 681-82 (9th Cir. 1999)
    (en banc). However, where the district court applies the
    wrong legal standard, we review the claim de novo. See
    Paulino v. Castro, 
    371 F.3d 1083
    , 1090 (9th Cir. 2004) (con-
    cluding that the state court applied the wrong standard by
    requiring defendant to “show a strong likelihood” of bias).
    The correct test for a prima facie case of discrimination is
    whether the defendant has shown that “(1) the prospective
    juror is a member of a cognizable racial group, (2) the prose-
    cutor used a peremptory strike to remove the juror, and (3) the
    totality of the circumstances raises an inference that the strike
    was motivated by race.” Boyd v. Newland, 
    467 F.3d 1139
    ,
    1143 (9th Cir. 2006) (internal quotation marks omitted), cert.
    denied, 
    127 S. Ct. 2249
     (2007). A pattern of striking panel
    members from a cognizable racial group is probative of dis-
    criminatory intent, but a prima facie case does not require a
    pattern because “the Constitution forbids striking even a sin-
    gle prospective juror for a discriminatory purpose.” United
    States v. Vasquez-Lopez, 
    22 F.3d 900
    , 902 (9th Cir. 1994);
    accord United States v. Esparza-Gonzalez, 
    422 F.3d 897
    , 904
    (9th Cir. 2005) (holding that prima facie case was shown
    where prosecutor struck the only Latino prospective juror as
    well as the only Latino potential alternate juror).
    When Collins objected to the government’s challenge of
    Juror No. 9, the district court offered the government the
    UNITED STATES v. COLLINS                   73
    opportunity to respond but the government declined, stating,
    “I don’t believe sufficient showing has been made.” The dis-
    trict court proceeded to rule that no prima facie case had been
    made. “First [African-American panel member was] excused
    by defense. First time [the government] has excused any
    [African-American panel members]. No pattern. No. Overrule
    without prejudice.” Collins protested, “I’m objecting that it
    can’t be a pattern because it’s the only one [African-American
    panel member] left.” The court did not address Collins’s argu-
    ment, but said “Okay. With the defense,” and voir dire contin-
    ued.”
    [3] Based on the court’s brief statements, we conclude that
    it applied an improper standard by requiring Collins to dem-
    onstrate a pattern of strikes against a cognizable racial group
    before requiring the government to state a reason. Vasquez-
    Lopez, 
    22 F.3d at 902
    . The government’s attempts on appeal
    to interpret the district court’s comments in any other way are
    unconvincing. Moreover, we conclude that the district court
    did not correct its error when Collins renewed his Batson
    motion after trial. Although the court recited the proper stan-
    dard at the post-trial hearing, it did not recognize its prior
    error: it said, “I have no reason to reverse the original ruling.”
    Consequently, we cannot be certain that the district court was
    not under the impression that a “pattern” of strikes was
    required. Therefore, we review de novo Collins’s equal pro-
    tection argument.
    [4] The first two elements of a prima facie case do not
    appear to be in dispute; Juror No. 9 is a member of a cogniza-
    ble racial group, and the prosecutor used a peremptory strike
    to remove her. Rather, the parties’ debate concerns whether
    the allegation gives “rise to an inference” of discrimination,
    which is a less burdensome standard of proof than the prepon-
    derance (“more likely than not”) standard. Johnson, 
    545 U.S. at 168
    . “[T]he burden for making a prima facie case is not an
    onerous one.” Boyd, 467 F.3d at 1151. At the prima facie
    stage of a Batson challenge, the burden of proof required of
    74                    UNITED STATES v. COLLINS
    the defendant is small, especially because proceeding to the
    second step of the Batson test puts only a slight burden on the
    government. This is because the government never bears the
    ultimate burden of persuading the district court that it did not
    act with a discriminatory purpose; that burden persists with
    the defendant. Johnson, 
    545 U.S. at 170-71
    . Rather, an easily
    met burden of proof momentarily shifts, at step two, to the
    government: to meet its burden, the government need only
    disclose its (nondiscriminatory) purpose for striking the
    potential juror. See 
    id. at 171
     (stating that the government sat-
    isfies its burden of proof even if it presents “only a frivolous
    or utterly nonsensical justification for its strike”). The ulti-
    mate burden then returns to the defendant at step three, and
    the defendant must persuade the district court that the govern-
    ment’s (nondiscriminatory) reason is pre-textual. 
    Id.
     A single
    inference of discrimination based on “all [the] relevant cir-
    cumstances” and the “totality of relevant facts” is sufficient to
    move the Batson inquiry to step two. See, e.g., Batson, 
    476 U.S. at 94, 96
    .
    [5] The government relies heavily upon Vasquez-Lopez, 
    22 F.3d at 902
    , where we said that “the fact that the juror was the
    one [b]lack member of the venire does not, in itself, raise an
    inference of discrimination.” See 
    id.
     (applying clear error
    standard of review). This should not be a controversial state-
    ment because it is not the prosecutor who chooses the panel
    members. Therefore, under a Batson challenge, we do not
    hold against the government the fact that the panel lacked
    African-American members.1 The lack of diversity in the
    panel, along with the removal of each African-American,
    however, does justify close scrutiny of the challenge. See
    United States v. Chinchilla, 
    874 F.2d 695
    , 698 n.5 (9th Cir.
    1989) (“However, although the striking of one or two mem-
    bers of the same racial group may not always constitute a
    1
    Collins does not raise a claim that the potential jurors were drawn from
    a nonrepresentative cross-section of the community. See Duren v. Mis-
    souri, 
    439 U.S. 357
    , 363-64 (1979).
    UNITED STATES v. COLLINS                           75
    prima facie case, it is preferable for the court to err on the side
    of the defendant’s rights to a fair and impartial jury.”). More-
    over, if we do not look closely at the prosecutor’s challenge
    of the sole African-American, it would be impossible for a
    defendant in Collins’s position to establish a case of prima
    facie discrimination.
    Courts have discussed several situations in which a prima
    facie case of discrimination may exist. The Supreme Court
    has said that the existence of a pattern of striking minority
    panel members is a relevant consideration that may raise an
    inference of discrimination. Batson, 
    476 U.S. at 96-97
    . We
    have found an inference of discrimination where the prosecu-
    tor strikes a large number of panel members from the same
    racial group, or where the prosecutor uses a disproportionate
    number of strikes against members of a single racial group.
    Fernandez v. Roe, 
    286 F.3d 1073
    , 1078 (9th Cir. 2002). Strik-
    ing members of more than one protected group is also rele-
    vant and may indicate a discriminatory intent. 
    Id. at 1079-80
    .
    A prosecutor’s questions and statements to the venire are rele-
    vant because they might provide insight into her motive. Bat-
    son, 
    476 U.S. at 97
    . Likewise, the fact that the prosecutor fails
    to “engage in meaningful questioning of any of the minority
    jurors” might indicate the presence of discrimination. Fernan-
    dez, 
    286 F.3d at 1079
    .
    [6] Despite a wealth of precedent in this area, this is a diffi-
    cult case because none of the aforementioned considerations
    apply. Juror No. 9 was the only African-American panel
    member subject to a strike by the government:2 The lack of
    other African-Americans in the jury pool renders mathemati-
    cal trends and patterns meaningless. The prosecutor may have
    only used 25% of his four challenges on African-Americans,
    2
    In total, there were three African-Americans on the venire. The first
    was struck by the defense, the second was Juror No. 9, and the third, a
    potential alternate juror, was struck for cause by the district court because
    he said it was his personal belief that anyone who went to trial was guilty.
    76                 UNITED STATES v. COLLINS
    but by the same logic, the prosecutor struck 100% of the
    remaining African-Americans from the jury. Moreover, the
    district court questioned the panel; therefore, we do not have
    the benefit of analyzing the prosecutor’s questions for dis-
    criminatory meaning.
    Collins argues that the prosecutor retained white jurors who
    gave answers similar to those given by Juror No. 9. Compara-
    tive juror analysis, a tool for conducting meaningful appellate
    review of whether a prima facie case has been established, is
    useful in analyzing such a claim. See Boyd, 467 F.3d at 1149-
    50 (holding that it was error for state appellate court not to
    review complete voir dire transcript because without such
    review there could be no comparative juror analysis);
    Esparza-Gonzalez, 
    422 F.3d at 904
     (stating that it is “relevant
    for the court to consider the differing treatment of similarly
    situated potential jurors”). Comparative juror analysis
    involves comparing the characteristics of a struck juror with
    the characteristics of other potential jurors, particularly those
    jurors whom the prosecutor did not strike. See Miller-El v.
    Dretke, 
    545 U.S. 231
    , 241, 247-48 (2005) (applying compara-
    tive juror analysis); Kesser v. Cambra, 
    465 F.3d 351
    , 360 (9th
    Cir. 2006) (en banc). An inference of discrimination may
    arise when two or more potential jurors share the same rele-
    vant attributes but the prosecutor has challenged only the
    minority juror.
    Juror No. 9 provided little information during voir dire. She
    lived in Compton, California, and was a medical records man-
    ager for USC Family Medicine. She did not state whether she
    was married or had children, but stated that no adult at home
    worked outside the house. Collins compares Juror No. 9’s
    answers to those of three other jurors who gave similar
    responses but were retained by the prosecutor: Juror No. 5, a
    health insurance claims examiner, who lived with her husband
    and 15 year-old son; Juror No. 6, a bookkeeper for a family-
    owned real estate business, who lived on the west side of Los
    Angeles and had prior civil jury experience; and Juror No. 10,
    UNITED STATES v. COLLINS                         77
    a financial analyst whose husband worked in computer sales
    and who had an adult daughter living at home. Collins con-
    tends that none of these jurors, like Juror No. 9, reported any
    connections or negative experiences with law enforcement,
    illegal drugs, or the criminal justice system.
    [7] In response, the government argues that these jurors are
    not similarly situated to Juror No. 9 because they were either
    married with children (Juror No. 5 and Juror No. 6) or had
    prior civil jury experience (Juror No. 6).3 The government
    cites these facts as potential non-racially motivated justifica-
    tions for a strike. Collins points out, however, that the govern-
    ment accepted another prospective juror, Juror No. 14, who
    was single and had no prior jury experience. Moreover, the
    record does not show whether Juror No. 9 actually had a hus-
    band or children. The court only asked the jurors to state
    whether there were “any adults living in the home that are
    employed outside of the home.” While several jurors used this
    question to identify the working adults as spouses or children,
    the court posed no question asking if jurors had a spouse or
    child. Juror No. 9 merely answered the question without giv-
    ing unsolicited answers. If the prosecutor was interested in
    marital or parenthood status, he does not appear to have asked
    the court to inquire specifically about that issue with Juror
    No. 9. Accordingly, comparative juror analysis does not
    reveal any meaningful distinctions between Juror No. 9 and
    other panel members who were retained by the government.
    [8] Thus, based on our review of the record, we conclude
    that an inference of discrimination did exist in this case. Com-
    parison of Juror No. 9’s characteristics with the characteristics
    of other similarly situated panel members who were allowed
    to serve reveals little distinction that could account for the
    prosecutor’s strike of Juror No. 9. In addition, the prosecutor
    3
    As a threshold matter, we note that there is no requirement that jurors
    be identically situated in order for meaningful comparison to take place.
    See Miller-El, 
    545 U.S. at
    247 n.6.
    78                    UNITED STATES v. COLLINS
    did not pursue further questioning before striking the only
    remaining African-American panel member. See Esparza-
    Gonzalez, 
    422 F.3d at 905
     (“[T]he prosecutor had very little
    hard information to base this decision on. Although the prose-
    cutor has no obligation to question all potential jurors, his
    failure to do so [before] removing a juror of a cognizable
    group . . . may contribute to a suspicion that this juror was
    removed on the basis of race.”). Finally, none of Juror No. 9’s
    answers to the court’s questions suggests a reason for her
    removal: nothing she said indicated a predisposition toward
    the defendant or a bias against the government.4 See Boyd,
    467 F.3d at 1147 (“[N]othing in the struck juror’s voir dire
    responses intimated a legitimate basis for removal.”).
    Although any of these factors standing alone may have been
    insufficient to establish a prima facie case, the totality of the
    circumstances raises an inference of impermissible discrimi-
    nation.
    [9] Consequently, the district court erred by not advancing
    to step two of the Batson inquiry. We remand, with instruc-
    tions that the court require the government to provide its rea-
    son for striking Juror No. 9. The district court should then
    determine, in the first instance, whether the strike was dis-
    criminatory.
    II.
    Collins next argues that the government failed to turn over
    an audiotape recording of a conversation between confidential
    informant Kim and Kim’s confederate Wenceslao Martinez,
    an individual not directly related to Collins’s case. The
    recording was finally disclosed, during post-trial proceedings.
    Collins contends that the recording establishes that informant
    Kim knew Oscar Torres, another drug dealer of Kim’s
    acquaintance, was looking to “get” Kim. Collins urges us to

    This is in stark contrast to the government’s other peremptory strikes,
    the reasons for which were readily apparent from the transcript.

    ing violated his right to due process under the Fourteenth
    Amendment. See Brady,

    reasonable probability that the disclosure of the evidence
    would have changed the trial’s result.” Ross,

    , 435 (1995)). In con-
    sidering this, “judges must undertake a careful, balanced eval-
    uation of the nature and strength of both the evidence the
    defense was prevented from presenting and the evidence each
    side presented at trial.” Id. at 1054 (internal quotation marks
    omitted). “In other words, the withheld evidence must be ana-
    lyzed in the context of the entire record.” Id. (internal quota-
    tion marks omitted).
    Collins gives three reasons why he believes the recording
    is favorable and material evidence. He contends that the
    recording (1) impeaches Kim by contradicting statements he
    made at trial, (2) similarly impeaches Agent Oz, and (3) is
    substantive proof that Kim had a motive to entrap Collins.5

    “Entrapment has two elements: (1) government inducement to commit
    the crime; and (2) the absence of predisposition to commit the crime. If
    the defendant is able to put entrapment in issue, the government bears the
    burden of negating the defense beyond a reasonable doubt.” Ross, 
    372 F.3d at 1108
     (citation omitted).
    80                  UNITED STATES v. COLLINS
    We consider together his two impeachment arguments.
    First, we observe that this is not a case in which the defense
    lacked notice of the alleged impeaching facts, such as the
    existence of the threat to Kim. Cf. Jernigan, 
    492 F.3d at
    1054-
    55. A Drug Enforcement Agency report of the recording was
    disclosed to Collins and documented the existence of the
    threat. Moreover, Collins asked Kim and Agent Oz about the
    threat on cross-examination. The question, then, is whether
    the recording of the actual conversation where the threat is
    relayed (as opposed to the fact of the threat) undermines con-
    fidence in the verdict.
    [11] With regard to the impeachment of Kim and Agent
    Oz, the recording adds little value. Evidence relevant to the
    impeachment of a witness adverse to the defendant may be
    favorable and material when “the reliability of the witness
    may be determinative of the defendant’s guilt or innocence.”
    United States v. Bracy, 
    67 F.3d 1421
    , 1428 (9th Cir. 1995).
    Kim’s reliability was important in refuting Collins’s conten-
    tion that he resisted committing the crimes and was convinced
    only through Kim’s persistence and withholding of other busi-
    ness opportunities upon which they were already involved
    together. However, there was already substantial evidence
    introduced at trial of Kim’s bias toward the government and
    his incentive to lie. For example, Kim admitted that he had
    been arrested for sending five pounds of methamphetamine to
    Hawaii and that he was cooperating with the government in
    exchange for several benefits, including release from jail
    without having to post a bond, cash, sentencing leniency, and
    immunity for other crimes. Furthermore, Kim’s restaurant, the
    source of his livelihood, was bought with drug money, and
    Kim admitted that the government had not (at the time of
    trial) made any inclination toward seizing the property or
    charging him with money laundering. In addition, the evi-
    dence of his bad character was overwhelming: Kim admitted
    that he smoked marijuana in jail, that he had been dealing
    drugs his entire adult life, that he dealt in quantities of drugs
    that netted him at least a million dollars in less than two years,
    UNITED STATES v. COLLINS                  81
    that he was arrested for committing domestic violence, and
    that he was arrested on another occasion where a handgun and
    a quarter pound of methamphetamine were seized from his
    house. Finally, Kim agreed that he was not the “type of per-
    son upon whose word someone can rely and count on.”
    Collins argues that the district court disregarded the value
    of impeachment by contradiction because Kim testified that
    he had never heard that another drug dealer (Torres) was mak-
    ing threats against him. Collins argues that the recording
    would have been evidence that Kim was lying because the
    recording reveals that Martinez told Kim that Torres was
    looking to “get him” and that he should stay away from Tor-
    res. However, Collins overstates the impeachment value of
    these statements. When asked about the phone conversation,
    Kim thrice said only that he did not remember learning about
    such a threat. Only after the fourth time, when asked by the
    district court, after some confusion, did Kim respond with a
    more definite “No, sir” to the question “Did anybody named
    Martinez ever call you up and talk to you about a threat on
    your life?” This exchange suggests that, even if Collins had
    the recording with which to impeach Kim, its impeachment
    value would have been little because on three occasions Kim
    said only that he did not remember a threat, not that one did
    not exist.
    Moreover, the fact that the threat was admitted into evi-
    dence by way of Agent Oz, who had listened to the recording
    and admitted that Martinez relayed a threat to Kim, under-
    mines the recording’s impeachment value as contradicting
    Kim’s trial testimony. Collins points out, however, that Agent
    Oz improperly characterized Kim’s response to that threat
    when she said, “I believe [Kim’s] comment [when told Torres
    was looking to kill him] was ‘I don’t think so.’ ” No such
    statement appears in the transcript of the recording. This, too,
    is weak impeachment evidence. Oz’s statement was tentative;
    she said, “I believe his comment was.” Furthermore, if we
    82                 UNITED STATES v. COLLINS
    keep reading Oz’s testimony, it is evident that she had a rea-
    son to believe that Kim did not take the threat seriously:
    He didn’t perceive a threat on his life. If I was to go
    into more detail about the relationship between those
    people I think you would understand why he didn’t.
    . . . The reason being . . . [Martinez and Torres] were
    always in a feud trying to get [Kim’s] business
    because he was a good customer. He bought a lot of
    dope from both of them. When that conversation was
    made it was after James Kim was released from jail.
    Her explanation is neither supported nor contradicted by the
    recording, and her explanation that she did not believe Kim
    took the threat seriously is not undermined by the tape. Con-
    sequently, we conclude that the recording has little value as
    impeachment evidence against either Kim or Oz. Certainly, it
    does not undermine our confidence in the verdict.
    [12] Finally, Collins contends the recording is material as
    proof that Kim actually knew about the threat and took it seri-
    ously. As we have explained, however, Agent Oz testified that
    a threat did exist. Kim admitted that he traded on his friend-
    ship with Collins to get Collins to find drugs for him on other
    occasions. Moreover, the existence of a threat was tangential
    to the question of whether Kim induced Collins to commit the
    crimes. In other words, Collins’s argument that the threat
    establishes a motive for Kim to entrap Collins—rather than
    setup more dangerous drug dealers threatening Kim—is atten-
    uated at best. The audiotape recording, while relevant and
    favorable, is not material, and its suppression did not infringe
    Collins’s right to due process.
    III.
    Collins also argues that the suppression of the tape violated
    his Sixth Amendment right of confrontation because he was
    unable to use the suppressed recording to impeach Agent Oz
    UNITED STATES v. COLLINS                   83
    and Kim. The primary purpose of the right of confrontation
    is “ ‘to secure for the opponent the opportunity of cross-
    examination.’ ” Davis v. Alaska, 
    415 U.S. 308
    , 315-16 (1974)
    (emphasis omitted) (quoting 5 J. Wigmore, Evidence § 1395
    (3d ed 1940)). Cross-examination affords an opportunity to
    demonstrate an adverse witness’ potential biases and motiva-
    tions. United States v. Larson, 
    495 F.3d 1094
    , 1102 (9th Cir.
    2007) (en banc), cert. denied, 
    128 S. Ct. 1647
     (2008). We
    have two standards of review for violations of the confronta-
    tion clause. De novo review applies when the district court
    excludes an area of inquiry. Larson, 
    495 F.3d at 1101
    . But we
    review for abuse of discretion a district court’s limitation on
    the scope of questioning. 
    Id.
    [13] Collins’s argument does not fit neatly within either
    claim because he is arguing, in effect, that suppression of
    material by the government, not the district court, violated his
    right to confront the witnesses against him in a meaningful
    manner. However, it is not clear that Collins’s contention is
    the law. See Pennsylvania v. Ritchie, 
    480 U.S. 39
    , 52 (1987)
    (plurality opinion) (stating that the confrontation clause is not
    a “constitutionally compelled rule of pretrial discovery”). We
    need not decide whether Ritchie controls this case, however,
    because we conclude that any violation was harmless beyond
    a reasonable doubt, for the same reasons we concluded that
    the recording was not material. See Larson, 
    495 F.3d at
    1107-
    08 (applying harmless error standard to confrontation clause
    claim). The recording was not so valuable as impeachment
    evidence that it affected Collins’s substantial rights.
    IV.
    Finally, Collins argues that the district court erred in refus-
    ing to order the government to serve a subpoena upon infor-
    mant Danny Yim, a resident of Hawaii. Yim was not involved
    in the two August transactions; rather, he was the buyer in an
    uncharged July methamphetamine deal, involving Collins and
    Kim. The government resisted disclosing Yim’s identity to
    84                 UNITED STATES v. COLLINS
    Collins because of Yim’s status as a confidential informant
    and because the government was not pursuing charges based
    on the July transaction.
    Collins, however, learned Yim’s identity independent of
    the government shortly before trial. Despite having learned
    Yim’s identity, Collins was unable to serve process upon
    Yim, as Yim avoided Collins’s investigators. The govern-
    ment, however, was still in contact with Yim, and Collins
    moved for the district court to order the government to pro-
    duce Yim or to accept service on behalf of Yim. The district
    court was skeptical of Yim’s relevance because Collins was
    not charged with the July transaction. Collins made an in
    camera proffer of the relevance of Yim’s testimony. He
    expected that Yim would testify that it was Kim who actually
    handed the drugs from the July transaction to Yim, not Col-
    lins; that Kim smoked methamphetamine with Yim; that Kim
    kept $6,000 of unreported money from the transaction; and
    that Kim helped Yim complete the drug deal by encouraging
    him to cash money orders in order to pay for the drugs. Col-
    lins contended that this evidence would show how Kim was
    desperate to entrap Collins in order to satisfy his debt to the
    government as a cooperating witness. The district court subse-
    quently denied Collins’s request, doubting its ability to order
    the government to serve a subpoena on behalf of the defense
    and remaining skeptical that Yim’s testimony was necessary
    to Collins’s entrapment defense.
    In Ritchie, the Supreme Court said that “[o]ur cases estab-
    lish, at a minimum, that criminal defendants have the right to
    the government’s assistance in compelling the attendance of
    favorable witnesses at trial and the right to put before a jury
    evidence that might influence the determination of guilt.” 
    480 U.S. at
    56 (citing cases). In Ritchie, and in the cases cited
    therein, the defendant was impeded from admitting favorable
    evidence because the government or the court took some
    action to block the defendant’s attempts. See 
    id. at 56-58
     (due
    process required that trial court review in camera confidential
    UNITED STATES v. COLLINS                  85
    report protected from disclosure by state law to determine if
    it was material to the defense); Cool v. United States, 
    409 U.S. 100
    , 102-03 (1972) (per curiam) (trial court violated
    defendant’s Sixth Amendment right to present exculpatory
    testimony of accomplice-witness when it instructed the jury
    that they could credit testimony only if they were convinced
    it was true “beyond a reasonable doubt”); Webb v. Texas, 
    409 U.S. 95
    , 97-98 (1972) (per curiam) (trial court impermissibly
    singled out convict-witness by implying that it expected the
    witness to lie and threatening the witness with prosecution for
    perjury where witness then refused to testify); Washington v.
    Texas, 
    388 U.S. 14
    , 23 (1967) (state violated defendant’s
    Sixth Amendment right of compulsory process by prohibiting
    defendant from admitting the testimony of an accomplice-
    witness).
    [14] Accordingly, and more specifically to the point in this
    case, we have said that, in some cases, the government has a
    duty to accept service of a subpoena for some confidential
    informants. United States v. Gonzalo Beltran, 
    915 F.2d 487
    ,
    488-89 (9th Cir. 1990) (per curiam). “A district court’s refusal
    to order the government to accept a subpoena for a confiden-
    tial informer produced the same effects as a decision to allow
    the government to exercise its privilege not to disclose the
    identity of a confidential informer.” 
    Id. at 488
    . We also stated
    that “[a]llowing the government to refuse to accept a sub-
    poena for an informer is also analogous to allowing the gov-
    ernment to deport witnesses whom a defendant may wish to
    subpoena.” 
    Id. at 489
    . In such cases, a “defendant cannot
    establish a violation of his right to compulsory process unless
    the defendant can show the testimony would have been ‘both
    material and favorable to the defense.’ ” 
    Id.
     (quoting United
    States v. Valenzuela-Bernal, 
    458 U.S. 858
    , 867 (1982)).
    [15] The similarity among all of these circumstances is that
    the government (or the court) is actively restraining or imped-
    ing the defendant from using a witness at trial. By contrast,
    Collins knew Yim’s identity prior to trial; the government
    86                  UNITED STATES v. COLLINS
    was not actively keeping Yim from testifying, either by pre-
    venting him from being served or by withholding his identity
    from the defense. Rather, Yim was resisting service of pro-
    cess. Collins argues that if the government had not resisted
    disclosing Yim’s identity, then he would have had more time
    in which to serve Yim. But, as Collins admits in his reply
    brief, he learned Yim’s identity before the district court had
    an opportunity to rule on the motion to compel disclosure.
    Consequently, we conclude that it was not the government’s
    fault that Yim did not testify and that there is no constitutional
    right that requires the government to accept service of sub-
    poena for Yim. To hold in Collins’s favor would create a rule
    that the government must accept a subpoena on behalf of any
    previously confidential informant that the defendant has been
    unable to serve through no fault of the government. The dis-
    trict court did not err.
    V.
    The judgment of the district court is AFFIRMED in part
    and REVERSED and REMANDED in part for the district
    court to conduct proceedings consistent with our opinion.
    GRABER, Circuit Judge, concurring:
    I concur fully in the opinion. I write separately only to
    encourage prosecutors to state their reasons for peremptory
    strikes at the time of a Batson challenge.
    As the opinion correctly holds, of course, if no prima facie
    case of discrimination has been made, a prosecutor is not
    required to give any explanation. The right to challenge a
    juror without cause is one that any litigant understandably
    wishes to guard. On the other hand, the burden of explaining
    the reasons for a challenge—in the alternative to arguing that
    no explanation is required—is minimal. Judicial economy
    UNITED STATES v. COLLINS                   87
    would be well served. See, e.g., Paulino v. Harrison, No. 07-
    55429, slip op. at 12179 (9th Cir. Sept. 4, 2008) (in a second
    appeal, upholding habeas relief in a Batson case when the
    prosecutor could not remember her reasons for exercising
    peremptory challenges at an evidentiary hearing held eight
    years after the trial). So would confidence in the fairness of
    a trial because, in fact, prosecutors usually have good and per-
    missible reasons for their challenges; refusing to state them
    can create unnecessary suspicion, as well as unnecessary liti-
    gation.
    O’SCANNLAIN, Circuit Judge, concurring in part and dis-
    senting in part:
    While I concur in Parts II, III, and IV of the court’s opin-
    ion, I cannot concur in Part I’s holding that there was a prima
    facie case of discrimination. Because I believe the panel
    majority applies the wrong standard of review and therefore
    reaches the wrong conclusion under Batson v. Kentucky, 
    476 U.S. 79
     (1986), I respectfully dissent from Part I of the court’s
    opinion.
    I
    Batson created a three-part burden shifting test which we
    must apply to ascertain if a juror was stricken for discrimina-
    tory reasons. See 
    id. at 96-98
    . Generally, we review a district
    court’s determinations at stage one of this test—whether a
    defendant has established a prima facie case of discrimination
    —for clear error. See Tolbert v. Page, 
    182 F.3d 677
    , 681-85
    (9th Cir. 1999) (en banc). The panel majority, however,
    adopts a de novo standard of review, asserting that the district
    court applied the improper legal standard. See Maj. Op. at 72-
    73 (citing Paulino v. Castro, 
    371 F.3d 1083
    , 1090 (9th Cir.
    2004)).
    88                     UNITED STATES v. COLLINS
    I am not so persuaded. Clear error review is appropriate
    here. Collins’ attorney objected to the government’s peremp-
    tory challenge of the remaining African-American juror, Juror
    No. 9, in open court.1 The district court overruled the objec-
    tion. According to the panel majority, the district court’s
    response suggests it believed a “pattern” of discrimination had
    to be shown. See Maj. Op. at 72-73. The majority rightly
    notes that under our precedent, such a showing is not required
    (and indeed would be impossible in situations where there is
    only one African-American juror on the panel). See United
    States v. Vasquez-Lopez, 
    22 F.3d 900
    , 902 (9th Cir. 1994).
    Rather, the Supreme Court has held that when assessing a
    stage-one Batson claim, the district court must determine
    whether the defendant has produced “evidence sufficient to
    permit the trial judge to draw an inference that discrimination
    has occurred.” Johnson v. California, 
    545 U.S. 162
    , 170
    (2005) (emphasis added).
    While the district court’s initial statement was perhaps
    inartfully worded, the court later clarified its language when
    responding to defendant’s motion for a new trial. The major-
    ity is correct to this extent: when rejecting Collins’ argument
    that he had established a prima facie Batson claim, the district
    court stated that it had “no reason to reverse the original rul-
    ing.” Maj. Op. at 73. But Judge Klausner—unlike the
    majority—did not stop there. The district court went on to say
    that “[t]here is no indication . . . that any of the facts or rele-
    vant circumstances have raised any inference that the chal-
    lenge was racially motivated.” The point was reiterated:
    “There is nothing in this case that [suggests] any inference
    that the challenge was racially motivated.” Thus, regardless of
    what the statement at trial might suggest, the district court
    clearly indicated that the “inference of discrimination” stan-
    dard enshrined in Johnson was applied. At the very least, any
    1
    Collins’ attorney had previously struck an African-American member
    of the venire. The district court, with the concurrence of both parties, also
    excused an African-American prospective alternate juror for cause.
    UNITED STATES v. COLLINS                            89
    potential legal error was cured.2 Accordingly, we should
    review the district court’s findings for clear error.
    II
    The panel majority correctly notes that only the third ele-
    ment of a prima facie case of discrimination is at issue:
    namely, does “the totality of the circumstances raise[ ] an
    inference that the strike was motivated by race.” Boyd v. New-
    land, 
    467 F.3d 1139
    , 1143 (9th Cir. 2006). The fact that the
    juror stricken was “the one [b]lack member of the venire does
    not, in itself, raise an inference of discrimination,”3 as the
    majority also appropriately emphasizes. Vasquez-Lopez, 
    22 F.3d at 902
     (“[I]t is not per se unconstitutional, without more,
    to strike one or more [b]lacks from the jury.” (citing Batson,
    
    476 U.S. at 101
    )); see also Maj. Op. at 74. Thus, to determine
    whether an “inference” of racial discrimination exists, the
    panel majority has only the nebulous “totality of the relevant
    facts” and circumstances to assess. Batson, 
    476 U.S. at 94
    ;
    Boyd, 467 F.3d at 1146. After such assessment, including the
    use of comparative juror analysis,4 the panel majority con-
    2
    At oral argument and in his reply brief, Collins asserts that the district
    court’s statement in response to the motion for a new trial should be con-
    sidered a “post-hoc” justification, “entitled to little weight.” Collins cites
    United States v. Mannino, 
    212 F.3d 835
    , 846 (3d Cir. 2000), in support of
    this claim. However, Mannino is inapposite, because in that case, the dis-
    trict court was hypothesizing about how it would have ruled in an alterna-
    tive scenario. In this case, the district court was not hypothesizing, but
    rather specifically stating the grounds for its decision.
    3
    While the statement is true, of course, it is again worth noting that
    Juror No. 9 was not the only African-American member of the venire in
    this case.
    4
    As the panel majority states, comparative juror analysis is a tool by
    which a court seeks out inferences of discrimination through a side-by-
    side comparison of the stricken juror and other potential jurors who were
    allowed to serve. See Boyd, 467 F.3d at 1147-48; Kesser v. Cambra, 
    465 F.3d 351
    , 362 (9th Cir. 2006); see also Miller-El v. Dretke, 
    545 U.S. 231
    ,
    241 (2005) (“If a prosecutor’s proffered reason for striking a black panel-
    ist applies just as well to an otherwise-similar nonblack who is permitted
    to serve, that is evidence tending to prove purposeful discrimination
    . . . .”).
    90                     UNITED STATES v. COLLINS
    cludes that the prosecutor’s actions “raise[ ] an inference of
    impermissible discrimination.” Maj. Op. at 78.
    I disagree. Considering the totality of circumstances, it is
    significant that Collins’ attorney struck the first African-
    American juror (Juror No. 2). Indeed, the prosecution had the
    opportunity to strike Juror No. 2 before Collins’ attorney did
    and declined to do so. While a pattern is not necessary for a
    finding of discrimination, the record nonetheless undermines
    any inference of discrimination. For similar reasons, it is rele-
    vant that Juror No. 9 was struck on the government’s third
    peremptory strike. Cf. United States v. Chinchilla, 
    874 F.2d 695
    , 698 (finding an inference of discrimination where the
    government used its first peremptory strike against a minority
    juror).
    Using comparative juror analysis, the panel majority and
    Collins claim that Juror No. 9 was situated similarly to Juror
    Nos. 5, 6, and 10.5 They assert that because the government
    struck Juror No. 9 but permitted the latter group to remain on
    the jury, a prima facie case of discrimination exists. However,
    an analysis of the voir dire transcript suggests entirely innocu-
    ous reasons for the government to dismiss Juror No. 9, but
    keep Nos. 5, 6, and 10.
    According to the transcript, Juror No. 9 was a female with
    no relationship to anyone in law enforcement, no negative
    experiences with law enforcement, and no prior jury experi-
    ence. Her familial status was unclear, but she stated that she
    did not live with any working adults. Juror Nos. 5, 6, and 10
    are similar in some respects, but there are significant differ-
    ences. Most notably, Juror No. 6 had prior civil jury experience,6
    5
    Collins also argues in his briefs that Juror No. 3 was similarly situated.
    However, unlike Juror No. 9, Juror No. 3 was dating a police officer and
    had previously served on a criminal jury.

    The panel majority and Collins argue that “prior jury experience” is not
    a sufficient basis upon which to distinguish Jurors No. 6 and No. 9
    UNITED STATES v. COLLINS                          91
    while Juror No. 5 and Juror No. 10 both indicated that they
    lived with another adult who worked outside the home. In
    fact, both Juror No. 5 and Juror No. 10 stated that they were
    married with children.
    Reasonable minds could differ as to the impact such dispar-
    ities could have on a juror’s service. However, there is no
    doubt that as the government asserts, these are “race-neutral,
    non-trivial” distinctions which cut against Collins’ claims that
    similarly situated jurors were treated differently. Given the
    deferential standard under which we review such determina-
    tions, see Tolbert, 
    182 F.3d at 681-85
    , on these facts, I cannot
    conclude that the district court committed clear error in ruling
    that no prima facie Batson claim was established.

    Because the majority employs the wrong standard of
    review and accordingly reaches what I believe to be an erro-
    neous conclusion, I am unable to join the court’s decision to
    remand for further proceedings on the Batson claim. I respect-
    fully dissent.
    because the prosecutor accepted another juror (Juror No. 14) who, like
    Juror No. 9, had not previously served on a jury. At a minimum, the two
    are not similarly situated because Juror No. 14 indicated that he lived with
    people who worked outside the home, said he had a relative whose partner
    worked in law enforcement, and stated that he could identify certain tat-
    toos which “indicate to [him] . . . things that [potential witnesses] have
    done.”
