    APPEAL FROM THE UNITED STATES DISTRICT COURT
    FOR THE DISTRICT OF NEW MEXICO
    (D.C. NO. 1:12-CR-00966-PJK-1)
    Margaret A. Katze, Assistant Federal Public Defender, Albuquerque, New
    Mexico, for Appellant.
    James R.W. Braun, Assistant United States Attorney (Damon P. Martinez, United
    States Attorney, with him on the brief) Albuquerque, New Mexico, for Appellee.
    Before TYMKOVICH, GORSUCH, and PHILLIPS, Circuit Judges.
    TYMKOVICH, Circuit Judge.
    Rayvell Vann was caught and convicted of carrying illegal drugs on an
    Amtrak train in New Mexico. He argues that he did not receive a fair trial
    because (1) the district court improperly denied his challenge to the government’s
    discriminatory strike of a potential juror because of the juror’s race; (2) the court
    improperly allowed expert testimony about the habits of drug traffickers; and (3)
    closing arguments misstated and embellished the evidence. Vann also contends
    that the district court erred in permitting him to waive his right to counsel during
    sentencing and proceed pro se.
    We conclude the district court did not err in finding the government’s
    reasons for dismissing the contested juror were racially neutral; the expert’s
    testimony was reliable based on his expertise and experience; and the prosecutor’s
    closing argument was not plainly erroneous. Moreover, we find no error in the
    district court’s decision to let Vann represent himself at sentencing. We exercise
    jurisdiction under 12 U.S.C. § 1291 and AFFIRM.
    I. Background
    Vann paid cash for a one-way Amtrak ticket for a two-day train ride from
    Los Angeles to Kansas City two hours before the train was set to depart. From
    his post in New Mexico, Agent Kevin Small of the Drug Enforcement Agency
    was tipped by a confidential source about the unusual circumstances of Vann’s
    Amtrak reservation.
    When the train made its regularly scheduled stop in Albuquerque, Agent
    Small boarded the train and located Vann. After a brief conversation, Agent
    Small asked to search Vann’s bags, and Vann consented. One of the bags
    -2-
    contained an out-of-place large pink gift box, and, after some discussion, Vann
    ultimately admitted that he was transporting codeine and painkiller pills.
    Vann was arrested, and a magistrate judge issued Agent Small a warrant to
    search the gift box. When Agent Small and another federal officer opened the
    box, they found padding that resembled home-insulation foam. After cutting into
    the foam, an odor of ether percolated from it, and the officers moved the
    receptacle outside to finish the process. After they finally opened it, they found
    two bottles of codeine, twenty-five OxyContin pills, and two jars containing
    approximately 100 grams of phencyclidine (PCP) apiece.
    Upon finding the narcotics, several officers, including Agent Small,
    interviewed Vann. During the interrogation, Vann admitted to dealing drugs in
    Nebraska and that he had purchased PCP in Los Angeles. He contended,
    however, that he had shipped the PCP he purchased via the United Parcel Service
    and thus did not know PCP was in the box.
    He was charged with possession with intent to distribute phencyclidine and
    codeine. A jury found Vann guilty of both charges. At sentencing, Vann excused
    his attorneys and proceeded pro se, and the district court ultimately sentenced him
    to fifteen years in prison.
    II. Analysis
    Vann raises four separate issues on appeal. First, he claims that the district
    court committed legal error during jury selection because it improperly
    -3-
    administered the three-part test under Batson v. Kentucky, 
    476 U.S. 79
    (1986),
    after the government used a peremptory strike against the sole African-American
    member of the venire. Second, Vann contends that the district court abused its
    discretion by allowing Agent Small to testify as an expert at trial. Third, he
    argues the district court plainly erred when it failed to sua sponte object to
    alleged misstatements by the prosecution during closing arguments. And fourth,
    he asserts error in the district court’s decision permitting him to waive his right to
    counsel during sentencing.
    We address, and ultimately reject, each of these arguments.
    A. Batson
    Vann first argues that the district court erred in rejecting a Batson
    challenge at trial and in a motion for a new trial.
    In the seminal case Batson v. Kentucky, 
    476 U.S. 79
    (1986), the Supreme
    Court made clear that the purposeful exclusion of a juror on the basis of race runs
    afoul of equal-protection principles in violation of a criminal defendant’s
    constitutional rights. As a result, it is impermissible for the prosecution, or any
    litigant for that matter, to use its challenges to strike a prospective jury member
    due to his or her race. 
    Id. at 85–86.
    Batson challenges are subject to the familiar burden-shifting framework
    that the Supreme Court further explained in Johnson v. California, 
    545 U.S. 162
    ,
    169–70 (2005):
    -4-
    First, the party challenging the strike as racially motivated “must make out
    a prima facie case ‘by showing that the totality of the relevant facts gives rise to
    an inference of discriminatory purpose.’” 
    Id. at 168
    (quoting 
    Batson, 476 U.S. at 93
    –94). If the district court moves on to steps two and three, as it did here, the
    “preliminary issue of whether the defendant had made a prima facie showing
    becomes moot.” Hernandez v. New York, 
    500 U.S. 352
    , 359 (1991).
    Second, if the proponent of the Batson challenge meets its initial burden on
    the prima facie case, then “the ‘burden shifts to the State to explain adequately
    the racial exclusion’ by offering permissible race-neutral justifications for the
    strikes.” 
    Id. (quoting Batson,
    476 U.S. at 94). The standard here is not high:
    “Although the prosecutor must present a comprehensible reason, ‘[t]he second
    step of this process does not demand an explanation that is persuasive, or even
    plausible’; so long as the reason is not inherently discriminatory, it suffices.”
    Rice v. Collins, 
    546 U.S. 333
    , 338 (2006) (quoting Purkett v. Elem, 
    514 U.S. 765
    ,
    767–68 (1995)).
    Finally, “‘if a race-neutral explanation is tendered, the trial court must then
    decide . . . whether the opponent of the strike has proved purposeful racial
    discrimination.’” 
    Johnson, 545 U.S. at 168
    (quoting 
    Purkett, 514 U.S. at 767
    ).
    “This final step involves evaluating the ‘persuasiveness of the justification’
    proffered by the prosecutor, but ‘the ultimate burden of persuasion regarding
    racial motivation rests with, and never shifts from, the opponent of the strike.’”
    -5-
    
    Rice, 546 U.S. at 338
    (quoting 
    Purkett, 514 U.S. at 768
    ); see also United States v.
    Nelson, 
    450 F.3d 1201
    , 1207 (10th Cir. 2006).
    We are concerned here only with the third step because each side concedes
    that its opponent met the burdens imposed at the first and second steps. The
    district court’s obligation at step three is to consider “all of the circumstances that
    bear upon the issue of racial animosity.” Snyder v. Louisiana, 
    552 U.S. 472
    , 478
    (2008); see also Miller-El v. Dretke, 
    545 U.S. 231
    , 251–52 (2005) (“[T]he rule in
    Batson . . . requires the judge to assess the plausibility of that reason in light of
    all evidence with a bearing on it.”). As our review of the district court’s
    application of Batson is a matter of process, we cannot assume that the district
    court evaluated the prosecutor’s credibility simply by virtue of its eventual ruling
    denying the Batson challenge. 
    Snyder, 552 U.S. at 479
    . 1
    Turning to the record, we recognize that the district court’s handling of the
    Batson challenge was streamlined. That said, at steps one and two, the Batson
    undertaking largely followed the blueprint. Indeed, after defendant raised the
    1
    We review the district court’s factual findings for clear error, United
    States v. Williamson, 
    53 F.3d 1500
    , 1508 (10th Cir. 1995), but we examine
    whether the district court applied the correct legal standard de novo, see e.g.,
    United States v. Yarrington, 
    640 F.3d 772
    , 778 (7th Cir. 2011). “The district
    court’s answer to the ultimate question of discriminatory intent represents a
    finding of fact of the sort accorded great deference on appeal because such a
    finding largely turns on the trial court’s evaluation of the prosecutor’s
    credibility.” 
    Nelson, 450 F.3d at 1207
    (internal quotation marks and citations
    omitted). In this case, however, Vann has not argued that the district court’s
    factual finding at Batson’s third step was clearly erroneous. For this reason, that
    argument is waived, and we do not address it here.
    -6-
    Batson challenge, the prosecution provided several nonracial reasons for striking
    the 49-year-old African-American juror:
    Your Honor, for starters, I had [this juror] singled out as
    a potential peremptory challenge prior to seeing him or
    knowing his ethnicity. [Co-counsel] can corroborate
    that.
    What I didn’t like about him, and the racially neutral
    reason as to why I am striking him, with race being no
    consideration, is, number one, he didn’t fill out the
    questionnaire. And I prefer having jurors that are
    educated, that have a stake in society, preferably with
    kids. He doesn’t even list an occupation, he’s seemingly
    unemployed. During the question-and-answer process,
    he seemed a little dazed and disengaged.
    So for those reasons, that’s my basis for striking him. I
    mean, especially – I can present this questionnaire to the
    Court. It’s not filled out. No, there’s no indication that
    he has any type of family or any type of job.
    App. Vol. V at 453–54.
    The prosecution next submitted the questionnaire as evidence, and the
    district court prematurely noted that “I will rule on your Batson argument.
    Nonracial reasons were given that make sense.” 
    Id. at 454.
    Usually, the district
    court would invite defense counsel to offer countervailing reasons as a rebuttal
    immediately following the government’s proffer of its nondiscriminatory reasons.
    This exchange would typically precede the district court’s ultimate decision on
    whether the given nondiscriminatory reason for the strike was genuine.
    -7-
    In this case, however, defense counsel recognized it was yet to be heard
    and requested an opportunity to rebut the government’s proposed reasons—the
    district court freely granted this request. Answering the call, defense counsel
    commented “[the juror] did respond when he was asked about prior juror service.
    He seemed attentive, articulate. I think there’s—we think the reasons offered by
    the government are disingenuous.” 
    Id. After that,
    the district court renewed its
    prior decision, stating “[the Batson challenge is] overruled, and the juror is
    stricken.” 
    Id. In light
    of those facts, the question we face is whether the district court
    committed legal error through its alleged failure to examine all of the
    circumstances surrounding the government’s professed reasons to strike the only
    African-American member of the jury pool. As we have said, based on Supreme
    Court precedent, the judge is required to “assess the plausibility of [the
    government’s nondiscriminatory] reason in light of all evidence with a bearing on
    it.” 
    Miller-El, 545 U.S. at 251
    –52 (emphasis added). Vann contends, at bottom,
    that the district court abdicated this responsibility, particularly because the record
    provides scant evidence of how the district court came to the conclusion that the
    government’s reasons were nondiscriminatory. 2
    2
    Vann’s briefing also implies that the district court’s approach, in and of
    itself, amounts to a misapplication of Batson. This is wrong because the court
    corrected any out-of-order concern by allowing defense counsel to make a
    response on the record. In any event, no rule requires that the district court even
    (continued...)
    -8-
    The record of the district court’s analysis at this point is sparse, of course.
    But that is not all that was developed on the claim. After trial, the defense filed a
    Rule 33 motion, arguing that all of the government’s race-neutral reasons for
    striking the African-American juror were pretextual. In this motion, defense
    counsel highlighted another member of the venire that was ultimately selected for
    jury service, whose questionnaire indicated that he might have been unemployed,
    like the stricken juror. It claimed this fact revealed the disingenuous nature of the
    government’s employment-related reason. Furthermore, Vann noted that the juror
    the government peremptorily struck had completed two years of college, which
    negated another of the government’s reasons; namely, that the juror was
    uneducated. As it had during jury selection, defense counsel also disputed the
    government’s description of the juror’s demeanor.
    The government responded to the motion and reasserted several of its
    reasons for striking the African-American juror, particularly stressing both his
    idiosyncratic failure to properly fill out the juror questionnaire 3 and his demeanor.

    hear from the party opposing the strike, only that it consider all of the relevant
    evidence. See Heno v. Sprint/United Management Co., 
    208 F.3d 847
    , 855 (10th
    Cir. 2000) (stating that the “trial court should ask challenging counsel to respond
    to the race-neutral reasons which have been proffered” (emphasis added)).
    3
    Of potential jurors who filled out the same form as the stricken juror,
    only one left the identical employment sections blank. That juror was never
    reached during the selection process because the jury was assembled prior to her
    number being called. Two other jurors did a less-than-complete job of filling out
    (continued...)
    -9-
    The government conceded that the stricken juror was as educated as persons
    selected to serve. It noted, however, that the juror’s indication that he completed
    only two years of college and his failure to specify a major suggested that he
    might have dropped out of college—this factor buttressed their suspicion based on
    his demeanor that he was disconnected from society. The government
    additionally responded to Vann’s argument about the similarly situated juror, a
    65-year-old Hispanic man. It challenged the relevance of the comparison because
    the juror chosen (1) completed a questionnaire, which was different from the
    excluded juror’s, that did not raise the same red flags for a failure to address
    several sections; and (2) was of retirement age and from an area where
    unemployment was more likely.
    The district court denied the motion. First, it stated that the similarity of
    some of the responses of the potential jurors was not enough to undermine the
    prosecutor’s race-neutral reasons. The court also found no showing of
    “purposeful discrimination,” under Batson and that a “credibility finding” was
    “implicit in the rationale for denying the objection: the government’s reasons
    were non-racial and rational.” App. Vol. III at 164.
    Based on our review of the entire record, we do not perceive a legal error in
    the application of the Batson test for several overlapping reasons. First, our case

    the similar sections, and the government used peremptory challenges against both
    of them.
    -10-
    law makes clear that the district court does not need to make a finding on the
    record with respect to how it assessed the evidence to rule on the Batson
    challenge. United States v. Castorena-Jaime, 
    285 F.3d 916
    , 929 (10th Cir. 2002);
    see also Saiz v. Ortiz, 
    392 F.3d 1166
    , 1180 (10th Cir. 2004) (“While explicit
    rulings are preferable, we can conclude in this case that the trial court implicitly
    ruled that the explanations offered by the prosecution were credible, believable,
    and race-and/or gender-neutral.”). 4 The bottom line is that a paucity of reasoning
    on the record to support the ultimate finding of nondiscrimination does not per se
    amount to a legal error in the application of Batson.
    In addition, when viewed from a wider lens, simply no evidence of animus
    existed for the district court to consider at the time it made its decision. The
    impartial district court must rely on the presentation of the parties in issuing its
    final ruling on a Batson challenge because, of course, there is no “independent
    duty on the trial court to pore over the record and compare the characteristics of
    jurors, searching for evidence of pretext, absent any pretext argument or evidence
    presented by counsel.” Johnson v. Gibson, 
    169 F.3d 1239
    , 1248 (10th Cir. 1999).
    And the record reveals that Vann did not present a comprehensive case during
    4
    A number of cases that Vann cites from other circuits do require that the
    district court explicitly state its factual findings of the prosecution’s credibility on
    the record. See, e.g., 
    Rutledge, 648 F.3d at 560
    (“Here too we conclude that
    remand is necessary for the district court to make explicit credibility findings.”).
    That rule does not come from the Supreme Court, however, and our prior
    decisions on this point control.
    -11-
    voir dire to counteract the government’s nonracially-motivated proffer. The
    prosecution submitted at least four separate nonracial reasons as to why it used a
    peremptory challenge against the African-American juror. In response, defense
    counsel only addressed the demeanor-based reason. 5 That left a minimum of three
    nondiscriminatory reasons intact. At least with respect to those reasons, we can
    hardly criticize the district court’s decision denying the Batson challenge because
    Vann “gave the district court no reasonable basis for questioning the
    government’s credibility in offering its race-neutral reasons.” United States v.
    Smith, 
    534 F.3d 1211
    , 1226 (10th Cir. 2008) (internal quotation marks omitted).
    Logically construed, the best way to interpret this series of events is that
    Vann failed to carry his burden of persuasion to demonstrate to the district court
    that the prosecutor’s use of a peremptory strike amounted to purposeful
    discrimination. This out-and-out failure is apparent on the record, and we refuse
    5
    It is true that when the juror’s demeanor is given as a reason for the
    strike, the trial court “must evaluate not only whether the prosecutor’s demeanor
    belies a discriminatory intent, but also whether the juror’s demeanor can credibly
    be said to have exhibited the basis for the strike attributed to the juror by the
    prosecutor.” 
    Snyder, 552 U.S. at 477
    . It is unclear how deep of a dive the district
    court took into the credibility of the demeanor-based reason for the government’s
    peremptory strike. Given that the government provided three additional reasons,
    however, we are hard pressed to find error in not fully analyzing the question of
    the stricken juror’s demeanor, notwithstanding the fact that the parties presented
    conflicting information.
    -12-
    to transform Vann’s inadequate effort to respond to the government into an error
    by the district court. 6
    To be sure, Vann further challenged the government’s proffered reasons
    after trial. With the benefit of hindsight, Vann constructed a rebuttal to the
    government’s nondiscriminatory reasons, challenging each as pretext for the
    allegedly racially motivated strike. We have serious reservations about a
    litigant’s decision to wait until his motion for a new trial to rebut certain of the
    government’s reasons. Other circuits share this concern, and some have found a
    Batson proponent’s failure to rebut the government’s nondiscriminatory reasons
    6
    Vann cites a number of extra-circuit cases where a court of appeals
    reversed the district court for failing to properly apply the Batson test. In many
    of those cases, the deficiency in the trial court’s application of Batson was
    apparent. See e.g., Coombs v. Diguglielmo, 
    616 F.3d 255
    , 263–64 (3d Cir. 2010)
    (finding that “it is clear from the record that the court effectively omitted the
    third step of the Batson inquiry by unreasonably limiting the defendant’s
    opportunity to prove that the prosecutor’s proffered reasons for striking Black
    jurors were pretextual, thereby improperly restricting the defendant’s ability to
    prove discriminatory intent” and criticizing the district court’s step two
    acceptance of the “prosecutor’s vague and elusive explanation and the apparent
    concession that he was not sure why he stuck Juror No. 1”); United States v.
    Collins, 
    551 F.3d 914
    , 922–23 (9th Cir. 2009) (reversing because the district
    court incorrectly ruled that step one of Batson required a pattern of racially
    motivated strikes); Jordan v. Lefevre, 
    206 F.3d 196
    , 201 (2d Cir. 2009) (“In an
    effort to save ‘an awful lot of time’ [the trial judge] ruled summarily on the
    Batson application after an extremely brief colloquy, and resisted counsel’s
    efforts to make arguments regarding the peremptory strikes so as to create a full
    record. The trial judge could not properly decide the third Batson step because he
    granted counsel no time to identify the relevant facts and assess the circumstances
    necessary to decide whether the race neutral reasons given were credible and
    nonpretextual. This cursory treatment of Jordan’s Batson application was not a
    meaningful inquiry . . . .”).
    -13-
    during the voir dire process amounts to forfeiture, see United States v. Jackson,
    
    347 F.3d 598
    , 605 (6th Cir. 2003), or even waiver, Wright v. Harris Cnty., 
    536 F.3d 436
    , 438 (5th Cir. 2008). Because we perceive no legal error by the district
    court under a less deferential standard, we need not go so far to decide this case.
    We will say, however, that such a rule is intuitively appealing, especially
    insofar as it appropriately matches the never-shifting burden of the Batson
    proponent to prove discriminatory intent behind the striker’s challenge.
    Practically speaking, a Batson challenge is best handled at the time when the
    judge and the attorney’s conduct are at issue, especially in a case like this one
    where defense counsel asserts that evidence of pretext came to light after the
    striker defends against the Batson challenge but before the jury is empaneled. See
    United States v. Hendrix, 
    509 F.3d 362
    , 371 (7th Cir. 2007) (finding no error
    when defendant fails to “cast doubt” on the government’s reasons “during voir
    dire”). Here, defense counsel could have specifically objected at any time during
    the process of voir dire. Yes, because the alleged pretext of some of the
    government’s reasons may only have been discovered as they sifted through the
    remainder of the venire, it would not make sense to require an absolutely
    contemporaneous rebuttal. But once the jury was comprised, Vann could have
    renewed his Batson challenge based on the comparison with the allegedly
    similarly situated juror, and likewise with any other reasons that sprouted up.
    This would have allowed the trial court to consider the questionnaires side-by-
    -14-
    side to address the government’s nondiscriminatory reasons. The fact that Vann
    waited until the jury was empaneled, the evidence was presented, and a verdict
    was rendered leaves the district court in a difficult spot. Instead, to preserve a
    Batson challenge, the best course of action is to address each of the government’s
    reasons at the time they were offered or when additional information is developed
    during voir dire.
    Even though we resist the application of waiver or forfeiture principles to
    Vann’s delayed rebuttal, in our review for legal error we underscore the nature of
    the information that was before the district court at the time of the Batson
    challenge; particularly, the uncontradicted nonracial reasons that remained for the
    government’s strike when jury selection closed. At that time, the district court
    was not presented with a side-by-side comparison of the stricken juror and his
    comparator. Nor did Vann challenge the government’s proffer of a lack of
    education or unemployment as reasons for the strike. Given the evidence
    presented to the district court during voir dire, we cannot find legal error in how
    it handled the Batson challenge.
    In any event, once the briefing on the motion for a new trial was before it,
    the district court reconsidered whether the nonracial reasons were pretextual
    based on the responsive reasons Vann provided. In other words, despite their
    untimeliness, those reasons were placed in front of the district court. But the end
    result was the same: Vann failed to meet his burden, and the district court
    -15-
    believed the government’s proffer of nonracial reasons. We thus ultimately
    cannot find error in the district court’s process at any point in the timeline.
    And finally, even though the district court’s review here was done in an
    abbreviated fashion, “[w]e traditionally presume, absent some indication in the
    record suggesting otherwise, that trial judges are presumed to know the law and
    apply it in making their decisions.” United States v. Ruiz-Terrazas, 
    477 F.3d 1196
    , 1201 (10th Cir. 2007) (quotation marks and alteration omitted). As a legal
    matter, we are convinced that the district court’s decision reflects a proper
    application of Batson—ending with a conclusion that, under the circumstances,
    the government’s facially nonracial reasons were credible and Vann failed to meet
    his burden to demonstrate otherwise. 7
    Considering the relatively sparse record on review, however, we emphasize
    that trial courts play a “pivotal role in evaluating Batson claims,” 
    Snyder, 552 U.S. at 477
    , and are the gatekeepers of fair juries. Batson cannot be reduced to a
    perfunctory check-the-box exercise, and, at step three, the district court must
    genuinely engage with the evidence presented by both sides to make a reasoned
    decision as to whether the government’s proffered nondiscriminatory reasons are
    genuine. We are satisfied that the district court did so here, but our task is
    7
    Vann also contends that the district court’s conclusion that “[n]onracial
    reasons were given that make sense” is only a step-two finding. Based on the
    record, we are convinced that, when combined with the district court’s reassertion
    that the Batson challenge was overruled because Vann failed to meet his burden,
    this was a step-three credibility finding.
    -16-
    considerably easier when we benefit from a factual record that memorializes the
    decision-making process at each step.
    In sum, we find the district court did not err in rejecting Vann’s Batson
    challenge.
    B. Expert Testimony
    Vann also claims that the district court erroneously allowed Agent Small to
    testify as an expert at trial. He particularly objects to testimony opining that PCP
    wholesalers do not typically package PCP for buyers, which solicited an inference
    that Vann must have knowingly packaged the PCP himself. This inference aimed
    to show that Vann was aware that he possessed a controlled substance, a
    necessary element of the crime charged. We review the district court’s decision
    to admit expert testimony for an abuse of discretion. United States v. Orr, 
    692 F.3d 1079
    , 1093–94 (10th Cir. 2012), cert denied, 
    133 S. Ct. 1300
    (2013). 8
    Expert testimony is admissible if it meets the standard set forth in Rule 702
    of the Federal Rules of Evidence: “A witness who is qualified as an expert by
    8
    The government contends that Vann’s failure to specifically object to the
    reliability of Agent Small’s expert testimony leaves our review only for plain
    error. Vann objected to Agent Small’s expert testimony in varying forms during a
    pretrial hearing and at trial, and we find these challenges sufficiently preserved
    the issue. And all things considered, this is not a case where a different result
    would occur as a result of our standard of review. For that reason, we review for
    an abuse of discretion.
    -17-
    knowledge, skill, experience, training, or education” can provide opinion
    testimony if:
    a) the expert’s scientific, technical, or other specialized
    knowledge will help the trier of fact to understand the
    evidence or to determine a fact in issue;
    b) the testimony is based on sufficient facts or data;
    c) the testimony is the product of reliable principles and
    methods; and
    d) the expert has reliably applied the principles and
    methods to the facts of the case.
    Fed. R. Evid. 702.
    Thus, the district court “must satisfy itself that the proposed expert
    testimony is both reliable and relevant, in that it will assist the trier of fact before,
    permitting a jury to assess such testimony.” United States v. Rodriguez-Felix,
    
    450 F.3d 1117
    , 1122 (10th Cir. 2006). As we said in United States v. Nacchio,
    this process has two parts:
    In determining whether expert testimony is admissible,
    the district court generally must first determine whether
    the expert is qualified “by knowledge, skill, experience,
    training, or education” to render an opinion. See Fed. R.
    Evid. 702. Second, if the expert is sufficiently qualified,
    the court must determine whether the expert’s opinion is
    reliable by assessing the underlying reasoning and
    methodology, as set forth in Daubert.
    
    555 F.3d 1234
    , 1241 (10th Cir. 2009) (en banc) (citing Daubert v. Merrell Dow
    Pharm., Inc., 
    509 U.S. 579
    (1993)).
    -18-
    Vann does not claim error in the district court’s finding that Agent Small
    was qualified to testify as an expert, and thus we only deal here with the
    reliability of the testimony. “[T]he law grants a district court the same broad
    latitude when it decides how to determine reliability as it enjoys in respect to its
    ultimate reliability determination.” Kumho Tire Co. v. Carmichael, 
    526 U.S. 137
    ,
    142 (1999). Along these lines, “our cases do not require district courts to
    extensively explain their reliability determinations.” United States v.
    Avitia-Guillen, 
    680 F.3d 1253
    , 1260 (10th Cir. 2012), cert. denied, 
    133 S. Ct. 466
    (2012).
    This court’s decision in United States v. Kamahele, 
    748 F.3d 984
    (10th Cir.
    2014), explains the circumstances under which police officers can testify as
    experts. That case reaffirmed that “police officers can testify as experts based on
    their experience ‘[b]ecause the average juror is often innocent of the ways of the
    criminal underworld.’” 
    Id. at 998
    (quoting United States v. Garcia, 
    635 F.3d 472
    ,
    477 (10th Cir. 2011)). Moreover, Kamahele specifically collected cases in which
    the court had allowed police officers to testify as experts regarding “means and
    methods of drug dealing.” 
    Id. (mentioning at
    least six cases that fit this model).
    Ultimately, the court upheld the officer’s testimony as an expert because he (1)
    “relied on multiple sources,” (2) “based his expert testimony on years of
    experience,” and (3) provided specific “insights into the distinctive traits” of his
    area of expertise. 
    Id. at 998
    –99.
    -19-
    Vann claims Agent Small’s testimony is unreliable because his experience
    in dealing with PCP is minimal and thus any criteria or data on which his
    opinions were based is insufficient. Furthermore, he argues that Agent Small
    fails to make a connection between some of the sources of his knowledge and his
    ultimate conclusions. But these arguments are unconvincing, especially insofar as
    Vann uses them to establish the district court’s abuse of discretion. The district
    court properly vetted Agent Small through a Daubert hearing and at trial,
    consistently giving the parties an opportunity to present their case for why Agent
    Small should or should not be allowed to testify. This process reflects due
    deliberation in a decision to admit an expert’s testimony as reliable. United
    States v. West, 
    671 F.3d 1195
    , 1201 n.6 (10th Cir. 2012). Indeed, on the basis of
    the record, this decision was well within the permissible scope of the district
    court’s authority.
    Even putting aside the deferential standard, Agent Small’s competence and
    reliability as an expert is not subject to criticism under the circumstances. He had
    worked numerous drug interdictions, observed legions of drug-smuggling
    methods, and caucused with criminals and professionals alike regarding the “tools
    of the drug trade.” This experience gave him dependable intelligence into the
    means and methods of drug transportation, as well as the typical relationship
    between wholesalers and dealers. And contrary to Vann’s assertions, Agent
    Small’s substantial experience in the drug trade generally is helpful in
    -20-
    establishing a foundation for his opinions and conclusions about PCP specifically.
    Regardless, Agent Small attested to numerous PCP arrests as well. Agent Small’s
    opinion testimony, acquired through his experience, training, and expertise as a
    DEA agent, was properly grounded and well reasoned—in short, it was reliable.
    Vann counters by pointing to a recent case where we found an abuse of
    discretion for admitting testimony of law enforcement personnel about drug
    traffickers display of “patron saints” for good luck while trafficking. See United
    States v. Medina-Copete, 
    757 F.3d 1092
    , 1105 (10th Cir. 2014). We held that it
    was inappropriate to admit speculative, meandering testimony regarding whether
    veneration of certain “narco” saints during a stop was evidence that the occupants
    of the vehicle knew that they were transporting drugs. Agent Small’s testimony is
    not vulnerable to the same attack.
    In addition, Medina-Copete is the exception not the rule, and, as noted, we
    have consistently allowed police officers to testify as to conclusions deriving
    from their expertise and experience. 
    Kamahele, 748 F.3d at 999
    ; United States v.
    Vazquez, 
    555 F.3d 923
    , 931 (10th Cir. 2009); 
    Garcia, 635 F.3d at 477
    ; United
    States v. Sturmoski, 
    971 F.2d 452
    , 459 (10th Cir. 1992); see also United States v.
    Roach, 
    582 F.3d 1192
    , 1206 (10th Cir. 2009) (collecting cases). At bottom, it is
    this circuit’s longstanding view that “police officers can acquire specialized
    knowledge of criminal practices and thus the expertise to opine on such matters.”
    United States v. Garza, 
    566 F.3d 1194
    , 1199 (10th Cir. 2009).
    -21-
    In the end, Vann cannot show an abuse of discretion in the district court’s
    decision to admit Agent Small’s expert testimony. As we noted in Nacchio, there
    is no abuse of discretion when “[t]here was a sufficiently developed record, a
    concrete reliability determination, and specific findings and discussion by the
    district court.” 
    Nacchio, 555 F.3d at 1256
    .
    C. Prosecutorial Misconduct
    Next, Vann claims the district court plainly erred in not sua sponte
    addressing alleged prosecutorial misconduct during closing arguments at trial.
    “[I]n cases of prosecutorial misconduct in which the defendant makes no
    objection, our precedent limits us to plain error review.” United States v. Taylor,
    
    514 F.3d 1092
    , 1095 (10th Cir. 2008). “Plain error occurs when there is (1) error,
    (2) that is plain, which (3) affects substantial rights, and which (4) seriously
    affects the fairness, integrity, or public reputation of judicial proceedings.”
    United States v. Alapizco-Valenzuela, 
    546 F.3d 1208
    , 1222 (10th Cir. 2008)
    (citations and quotation marks omitted).
    We use a two-step process when considering claims of prosecutorial
    misconduct. United States v. Ivy, 
    83 F.3d 1266
    , 1288 (10th Cir. 1996). First, we
    determine whether the conduct was improper; if so, we decide whether the
    improper conduct warrants relief. 
    Id. On plain-error
    review, the burden is on the
    defendant, and “reversal is warranted only when: (1) the prosecutor’s statement is
    plainly improper and (2) the defendant demonstrates that the improper statement
    -22-
    affected his or her substantial rights.” United States v. Fleming, 
    667 F.3d 1098
    ,
    1103 (10th Cir. 2011); see also United States v. Gonzalez-Montoya, 
    161 F.3d 643
    ,
    650 (10th Cir. 1998) (“In evaluating . . . incidents [of prosecutorial misconduct]
    for plain error, we will reverse only if, after reviewing the entire record, we
    conclude that the error is obvious and one that would undermine the fairness of
    the trial and result in a miscarriage of justice.” (quotation marks omitted)).
    “[R]eversal in the absence of contemporaneous objection is a rare exception
    rather than the rule.” United States v. Hill, 
    749 F.3d 1250
    , 1267 (10th Cir. 2014).
    “When evaluating allegedly inappropriate remarks of counsel for plain
    error, we must view the remarks in the context of the entire trial.” United States
    v. Lopez-Medina, 
    596 F.3d 716
    , 738 (10th Cir. 2010) (quotation marks omitted).
    And even when a remark during closing arguments is improper, curative
    instructions will typically immunize such a statement from affecting defendant’s
    substantial rights. See United States v. Rogers, 
    556 F.3d 1130
    , 1140–41 (10th
    Cir. 2009). Indeed, when “the jury was properly instructed that [statements and]
    arguments [of counsel] are not evidence and that [defendant] [c]ould only be
    convicted on the basis of evidence submitted at trial,” 
    id., we have
    consistently
    refused to find plain error based on misstatements by the prosecutor. See United
    States v. Fleming, 
    667 F.3d 1098
    , 1106 (10th Cir. 2011).
    Vann makes three claims of error, the first two of which target the
    prosecution’s presentation of related circumstantial evidence in its theory of the
    -23-
    case at closing, a theory that Vann labels “demonstrably false.” Aplt. Br. at 50.
    In short, the theory of the prosecution’s case for conviction was that, because
    Vann could have without incident walked on a plane with the codeine and the
    painkillers, his decision to take a train must have been with an awareness that he
    was smuggling PCP. Broadly speaking, Vann contends that this theory misstates
    the evidence. First, Vann points to the fact that the names were scratched off the
    bottles of codeine in this case. That evidence partially runs counter to Agent
    Small’s testimony that codeine is “something you can have with you on an
    airplane. Your name is on it, whatever, you can take it with you . . . It’s not a
    difficult thing.” App. Vol. V at 478–79. Thus, according to Vann, when the
    prosecution referred back to Agent Small’s testimony during closing in order to
    support its theory, it did so deceptively.
    Along the same lines, Vann argues that the prosecution’s construction of
    the evidence in closing was improper because Agent Small testified at the
    Daubert hearing that he “intercepted a lot of codeine cough syrup on the trains.”
    App. Vol. V at 229. As best as we can tell, Vann’s complaint is that this
    concession weakened the inference regarding Vann’s state of mind and this
    weakness should have been exposed to the jury. Taken together, these claims of
    errors find fault in the prosecutor’s broad counterfactual codeine-on-an-airplane
    theory.
    -24-
    As an initial matter, Vann’s argument misapprehends the purpose and
    nature of circumstantial evidence. Circumstantial evidence is indirect and thus it
    requires its proponent to ask that the jury draw a particular inference from certain
    information. Inferences vary in their strength, and the fact finder must evaluate
    whether an inference makes sense and weigh it accordingly. When a litigant
    argues that a piece of circumstantial evidence should lead the jury to a certain
    conclusion, that litigant is not committing misconduct or misstating the
    evidence—he is, to be blunt, lawyering. United States v. Dazey, 
    403 F.3d 1147
    ,
    1170 (10th Cir. 2005) (“The prosecutor is entitled to argue to the jury that it
    should draw reasonable inferences from the evidence to support the government's
    theory of the case.”).
    To prove that Vann knowingly transported the PCP, the government relied
    on a string of reasonable inferences—some stronger than others—that sought to
    show Vann’s state of mind and knowledge. Desert Palace, Inc. v. Costa, 
    539 U.S. 90
    , 100 (2003) (“[W]e have never questioned the sufficiency of
    circumstantial evidence in support of a criminal conviction, even though proof
    beyond a reasonable doubt is required.”). Given the abstract nature of the mens
    rea, this tactic is as uncontroversial as it is ubiquitous. United States v. Santos,
    
    553 U.S. 507
    , 521 (2008) (finding that “knowledge must almost always be
    proved” by circumstantial evidence); see also United States v. Haymond, 
    672 F.3d 948
    , 957 (10th Cir. 2012), cert. denied, 
    132 S. Ct. 2789
    (2012) (“[A] showing of
    -25-
    means rea may and often is inferred from circumstantial evidence.” (internal
    citations and quotation marks omitted)).
    Moreover, even conceding the alleged discrepancies between the evidence
    presented and statements made during closing, we simply do not see the
    prosecutor’s statements as improper in any way, as they were “grounded in earlier
    testimony and . . . relevant to an element of the crime.” Stouffer v. Trammell, 
    738 F.3d 1205
    , 1224 (10th Cir. 2013). Similar to the situation in United States v.
    Woods, 
    764 F.3d 1242
    (10th Cir. 2014), these “comment[s] [are], at worst,
    ambiguous and allow[] for several interpretations.” 
    Id. at 1246.
    With respect to
    the first statement, placing all of the stock in Agent Small’s comment that “[y]our
    name is on it” misses the mark. The point is that prescription medications, unlike
    substantial quantities of PCP (or another liquid), have a decent chance of making
    it through the airport security, whether in your carry-on or checked bag (and
    regardless of whether the names were displayed on the bottles). This was all part
    and parcel of a theory that someone carrying PCP may choose Amtrak.
    Nor does the fact that Agent Small had previously intercepted criminals
    transporting codeine on trains transform the prosecution’s theory into an
    impropriety. In Vann’s view, the government’s theory was entirely deductive—
    all drug dealers knowingly carrying only codeine use airplanes exclusively; Vann
    took a train; Vann was knowingly carrying more than codeine. Thus, says Vann,
    Agent Small’s concession that he has picked up codeine transporters on the train
    -26-
    reveals a logical fallacy. Of course, this indisputable syllogism was not the
    government’s case; rather, it simply argued that, in conjunction with the other
    evidence, it was unlikely that Vann would have taken the train unless he knew he
    was carrying PCP. Ultimately, the fact that the government’s theory was not
    airtight does not mean that it misstated the evidence. To be sure, the
    government’s theory is weakened by the fact that persons carrying codeine have
    been caught on trains or that the codeine bottles were without names, but that
    does not reveal the prosecutors’ misconduct. Sliced any way, these statements
    were not plainly improper.
    In addition, the district court instructed the jury that the lawyers’
    “statements and arguments are not evidence,” App. Vol. I at 511, and the
    prosecutor even issued the same caution at the outset of his closing argument,
    “[i]t’s always important to keep in mind that whatever us lawyers say, that is not
    evidence, so you need to go with your own memory of the testimony and the
    evidence, and make sure that everything that’s said is in line with the evidence,”
    App. Vol. 5 at 620–21. In light of these efforts to mitigate any misstatements—to
    the extent they can be considered misstatements—any error by the district court in
    not responding sua sponte is not reversible on plain-error review.
    And finally, assuming for the sake of argument that the district court erred,
    the unobstructed admission of these statements did not affect Vann’s substantial
    rights. United States v. Rosales-Miranda, 
    755 F.3d 1253
    , 1258 (10th Cir. 2014)
    -27-
    (“An error seriously affects the defendant’s substantial rights . . . when the
    defendant demonstrates that there is a reasonable probability that, but for the
    error claimed, the result of the proceeding would have been different.” (internal
    quotation marks and citation omitted)). Although it was circumstantial, the
    government presented significant evidence to permit a reasonable fact finder to
    conclude beyond a reasonable doubt that Vann knowingly possessed the PCP,
    including: (1) evidence that he admitted during an interview to purchasing PCP in
    Los Angeles; (2) evidence that he admitted to dealing drugs; (3) evidence of the
    suspicious plane-one-way-train-the-other travel plan; (4) evidence of his
    demeanor and inculpatory statements when confronted on the train; (5) evidence
    that it is unnecessary to travel to Los Angeles to purchase codeine and
    OxyContin; and (6) evidence that drug dealers typically purchase PCP out of Los
    Angeles. By any standard, the evidence was enough for the jury to convict
    without the alleged misstatements. See 
    Woods, 764 F.3d at 1248
    (explaining that
    where the other evidence of guilt is strong, any error by the district court in not
    correcting alleged prosecutorial misstatements does not affect defendant’s
    substantial rights). For this reason, Vann’s substantial rights were not affected by
    the alleged misstatements.
    On the third claim of misconduct, Vann claims the government improperly
    argued in rebuttal that the typical lower-level drug transporter, or “mule,”
    regularly breaks down when he finds that he is carrying more than he bargained
    -28-
    for. The government described Vann’s reticent reaction to the revelation that the
    agents found PCP in the box and used this argument to contend that Vann must
    have known he was carrying the PCP. The government had not, however,
    presented this as evidence during trial through the testimony of Agent Small or
    otherwise—a fact the government concedes. Aple. Br. at 28. Taken in context,
    however, this comment was merely a description of Vann’s reaction and
    demeanor when he was arrested. It was meant to emphasize the casualness and
    acknowledgment of the circumstances of his arrest.
    In any event, we have held in the past that a reference to facts not in
    evidence does not necessarily constitute plain error mandating reversal. See
    United States v. Oles, 
    994 F.2d 1519
    , 1524 (10th Cir. 1993). Furthermore, in a
    nearly identical context, we have found that a curative instruction negates the
    effect of the prosecution’s reference to facts outside of evidence in rebuttal. See
    United States v. Lawson, 
    968 F.2d 21
    , at *3 (10th Cir. 1992) (unpublished table
    decision). In this case, the district court provided a curative instruction.
    In sum, even assuming this was an error, it was neither plain nor did it
    affect substantial rights for all of the reasons expressed above.
    D. Waiver of Right to Counsel
    Finally, Vann argues that he did not knowingly waive his right to counsel at
    sentencing.
    -29-
    We review the validity of a waiver to the right to counsel de novo. United
    States v. Turner, 
    287 F.3d 980
    , 983 (10th Cir. 2002). It is well-settled that a
    criminal defendant retains his right to counsel during the sentencing phase of his
    case. Gardner v. Florida, 
    430 U.S. 349
    , 358 (1977). At any phase of the judicial
    proceedings, a defendant is permitted to represent himself as a matter of right,
    Faretta v. California, 
    422 U.S. 806
    , 819 (1975), and can do so by waiving his
    right to counsel. The waiver, however, must be “an intentional relinquishment or
    abandonment of a known right or privilege.” United States v. McConnell, 
    749 F.2d 1441
    , 1450–51 (10th Cir. 1984).
    In the normal course, we examine whether a defendant has effectively
    waived his right to counsel under a two-part test. “First, we must determine
    whether the defendant voluntarily waived his right to counsel [and] [s]econd, we
    must determine whether the defendant’s waiver of his right to counsel was made
    knowingly and intelligently.” United States v. Taylor, 
    113 F.3d 1136
    , 1140 (10th
    Cir. 1997). In this case, the voluntariness of Vann’s waiver is not suspected;
    thus, only the second prong is at issue.
    We reflect on the totality of the circumstances to decide whether a
    defendant has knowingly decided to proceed pro se. As we have noted, the true
    test for an intelligent waiver “turns not only on the state of the record, but on all
    the circumstances of the case, including the defendant’s age and education, his
    -30-
    previous experience with criminal trials, and representation by counsel before
    trial.” United States v. Padilla, 
    819 F.2d 952
    , 958 (10th Cir. 1987).
    To this end, the tried-and-true method for establishing that a waiver was
    knowing and intelligent is to “conduct a thorough and comprehensive formal
    inquiry of the defendant on the record to demonstrate that the defendant is aware
    of the nature of the charges, the range of allowable punishments and possible
    defenses, and is fully informed of the risks of proceeding pro se.” United States
    v. Willie, 
    941 F.2d 1384
    , 1388 (10th Cir. 1991). This so-called Faretta hearing
    ensures the defendant is not unwittingly or impulsively disposing of his
    constitutional right to counsel.
    And while the hearing itself is a known quantity, we have recognized that
    “[t]here are certain limited situations . . . where a waiver may be valid” even
    when the inquiry by the court is deficient. United States v. Hughes, 
    191 F.3d 1317
    , 1323 (10th Cir. 1999). In Hughes, for example, we found that “a waiver
    may be valid absent an inquiry by the court where ‘the surrounding facts and
    circumstances, including [the defendant’s] background and conduct, demonstrate
    that [the defendant] actually understood his right to counsel and the difficulties of
    pro se representation and knowingly and intelligently waived his right to
    counsel.’” 
    Id. (quoting Willie,
    941 F.3d at 1389) (brackets in Hughes).
    All of this goes to say that the Faretta hearing is one way—probably the
    best way—for the district court to satisfy itself that defendant’s waiver of a right
    -31-
    to counsel was done intelligently. But as the Eleventh Circuit persuasively
    concluded in a recent case, a Faretta hearing is only “a means to [an] end” of
    ensuring a voluntary and intelligent waiver, and the absence of that means is “not
    error as a matter of law.” United States v. Stanley, 
    739 F.3d 633
    , 645
    (11th Cir. 2014), cert. denied, 
    134 S. Ct. 2317
    (2014). In other words, a
    contemporaneous and comprehensive hearing is generally a sufficient condition to
    a knowing waiver, but it is not a necessary one.
    Moreover, although the timing of the Faretta hearing is certainly important,
    other courts have found that a proper Faretta hearing is not negated when
    defendant hesitates or declines to proceed pro se initially before later reasserting
    an interest to do so. United States v. Modena, 
    302 F.3d 626
    , 631 (6th Cir. 2002)
    (“Although Modena had an interim change of heart regarding his decision to
    proceed pro se, he ultimately gave the district court no reason to suspect that he
    was uncertain about representing himself.”). That point resonates here, as the
    government concedes that the district court did not perform a “thorough and
    comprehensive formal inquiry” of Vann immediately preceding his waiver during
    sentencing. See Aple. Br. at 32–33.
    Instead, the government contends that the inquiry performed in advance of
    trial was sufficient to satisfy the requirement. At that hearing, Vann ultimately
    withdrew his request to represent himself, but the court satisfactorily explained
    the dangers of self-representation. As we see it, there is no question that the
    -32-
    district court’s colloquy was sufficient vis-à-vis Vann’s trial representation: the
    court thoroughly examined defendant and articulated the responsibilities and
    drawbacks of representing oneself. App. Vol. V at 265–73.
    The inquiry prior to sentencing, by contrast, did not go into the same depth,
    and Vann stresses that the three-month span between trial and sentencing
    essentially neutralizes the efficacy of the earlier hearing. Prior to sentencing, the
    court did, however, discuss with Vann the problems that he was having with his
    lawyers and queried why he wanted to relieve them of their representation. The
    court also informed defendant that it thought his current counsel was competent
    and would do a better job advocating for Vann during the sentencing phase than
    he could do himself. Importantly, the district court also expressed concern about
    the delays associated with finding new attorneys, noting that “[y]ou have had two
    sets of lawyers. You have fired them both. Now, you want additional ones, and
    it’s just delay.” App. Vol. V at 703. Nevertheless, Vann chose to self-represent.
    It is clear from the record that the circumstances of this case permitted the
    district court to forego an additional comprehensive inquiry into waiver. In the
    main, the district court had explained the risks of self-representation throughout,
    including the detailed discussion prior to trial. Vann points to no case holding
    that an earlier, in-depth Faretta hearing cannot satisfy the constitutional standard
    when a defendant later waives his right to counsel. In the same vein, we have
    found nothing authoritative that requires a separate hearing of equal depth each
    -33-
    time the option of proceeding pro se arises. Such a rule would be unworkable.
    Again, the standard is simply that defendant is fully aware of the consequences of
    his decision to proceed without counsel. 9 The district court found that he was,
    and we agree.
    To be sure, a better course of action might be to re-conduct the colloquy to
    confirm the waiver. Still, in light of the district court’s ongoing dialogue with
    defendant regarding his issues with his attorneys and his desire for
    self-representation, the district court correctly assessed the totality of the
    circumstances surrounding defendant’s decision to excuse his attorneys and did
    not err in concluding that Vann’s waiver was knowing and intelligent.
    III. Conclusion
    We AFFIRM the district court’s decision.
    9
    The district court’s concern that Vann was delaying the proceedings by
    firing counsel and requesting new lawyers also brings this case directly into the
    guidance of Hughes, which found that purposeful delay by defendant evidenced a
    valid waiver. See 
    Hughes, 191 F.3d at 1324
    . Thus, the district court’s awareness
    of possible dilatory tactics further supports the decision to forego a subsequent
    Faretta hearing.
