    APPEAL FROM THE UNITED STATES DISTRICT COURT
    FOR THE DISTRICT OF KANSAS

    Before TYMKOVICH, Chief Judge, MATHESON and MORITZ, Circuit
    Judges.
    TYMKOVICH, Chief Judge.
    A jury convicted Jonathan Kearn of federal child pornography charges
    arising from pictures he took of his four-and-a-half year old daughter and shared
    on the internet. He was sentenced to a lengthy prison term followed by five years
    of supervised release.
    Kearn contends the district court committed various errors at trial and
    sentencing. First, Kearn raises several evidentiary objections. He argues that the
    government elicited hearsay testimony when it asked a witness about the contents
    of an inculpatory report written by an expert who did not testify at trial. Even
    assuming this testimony was hearsay, however, we find no plain error, since
    admitting it did not affect the outcome of the trial. Kearn also argues that
    testimony identifying certain images as “child pornography” was inadmissible,
    because it was not helpful to the jury. The testimony was helpful, however, since
    whether the images depicted sexually explicit conduct was a fact in issue. The
    testimony also helped explain steps in the investigation. Finally, Kearn argues
    that evidence was improperly admitted under Federal Rule of Evidence 404(b),
    but he fails to direct us to any evidence actually admitted under that rule.
    Second, Kearn argues the jury should have been instructed that they had to
    agree unanimously on which specific images formed the basis for conviction. In
    his view, all of the jurors had to agree that at least one specific image violated
    federal law. But this misstates the case law: unanimity is only required for
    elements of a crime, not for means of satisfying a given element. Different
    images satisfying the statutory criteria are merely different means.
    -2-
    Third, Kearn argues that a supervised-release condition that will prohibit
    him from contacting his victim—his youngest daughter—was improper, because it
    was not “reasonably related” to the offense of conviction, and because it
    interfered with his right of familial association. But he has waived these
    arguments, which he did not make at sentencing, by failing to argue for plain
    error.
    Finally, Kearn argues that the cumulative effect of the errors in this case
    mandates reversal. But we only identify one possible error here, so cumulative
    error analysis—which addresses whether multiple errors can prejudice a
    defendant—is unavailing.
    We thus conclude that none of the issues Kearn raises requires reversal.
    I. Background
    Detective Sergeant Stuart Butler, a police investigator in Australia,
    operated an undercover online persona that purports to trade in child pornography
    in order to help catch perpetrators. In 2013, “cheyenneandliberty@yahoo.com”
    began an e-mail exchange with Detective Butler, during which
    “cheyenneandliberty” sent several images of young girls later identified as
    Kearn’s daughters. In most of the pictures the girls were clothed, but one of the
    images showed the genitals of Kearn’s youngest, four-and-a-half year old
    daughter. “Cheyenneandliberty” also sent Detective Butler a link to three explicit
    videos of young girls who were not Kearn’s daughters. In these e-mails,
    -3-
    “cheyenneandliberty” described himself as a thirty-eight year old from Kansas,
    and a single father to four daughters: a four-and-a-half year old, two ten-year-old
    twins, and a thirteen year old. When Detective Butler asked him for a family
    photo, “cheyenneandliberty” sent him a photograph of Kearn standing with three
    of his daughters.
    Detective Butler looked at the data embedded in the digital images, which
    shows when they were taken and the device used to take them. The data showed
    the explicit images were taken with an iPhone 4s shortly before
    “cheyenneandliberty” sent the e-mails. This fact indicated to Detective Butler
    that “cheyenneandliberty” was not merely sending images he found on the
    internet, but taking the images himself. He therefore referred the exchange to the
    U.S. Department of Homeland Security.
    Investigators found the IP address used to send some of the images was
    associated with Kearn’s Kansas home address. Kearn’s age, family situation, and
    location matched the description given by “cheyenneandliberty.” Investigators
    executed a search warrant at Kearn’s house. Kearn’s daughters were present, and
    the investigating agent, Special Agent Cassidy Casner, recognized the girls from
    the images sent to Detective Butler. Investigators seized Kearn’s iPhone 4s—the
    same model that had taken the photographs—and footage from his home security
    system.
    -4-
    When Agent Casner reviewed the home security footage, it corroborated the
    e-mails sent to Detective Butler and the embedded data from the images. That is,
    the footage confirmed that Kearn was using his phone when the e-mails were sent;
    Kearn was with his daughters when the pictures were taken; and the daughters
    were wearing the same clothes shown in the pictures on the dates the pictures
    were taken.
    A grand jury indicted Kearn with (1) permitting his minor child to engage
    in sexually explicit conduct in violation of 18 U.S.C. § 2251(b); (2) distributing
    child pornography in violation of 18 U.S.C. § 2252(a)(2); and (3) possessing child
    pornography in violation of 18 U.S.C. § 2252(a)(4)(B).
    At trial, in addition to the home security footage and the e-mail exchange
    with Detective Butler, the government presented the expert testimony of Special
    Agent Craig Beebe, who specializes in forensic examinations of electronic
    evidence. Agent Beebe testified that Kearn’s iPhone contained explicit images of
    young girls, evidence of the “cheyenneandliberty” e-mail address, and two videos
    of Kearn’s youngest daughter naked with Kearn’s voice in the background. Agent
    Beebe also found one of the images e-mailed to Detective Butler on the iPhone.
    On Kearn’s computer, Agent Beebe found further evidence of
    “cheyenneandliberty,” the website through which Detective Butler’s undercover
    persona was contacted, and “ProudPapa,” a nom de plume used in the e-mails
    with Detective Butler.
    -5-
    Kearn testified at trial. He admitted he had taken the explicit photo and
    videos of his youngest daughter. But in his defense, he said she had reported
    being molested by her mother’s boyfriend and he had taken the photos and videos
    as evidence of the molestation. A sheriff’s report indeed showed that Kearn had
    reported this alleged molestation to the sheriff a year before the e-mail exchange
    with Butler. Kearn denied any knowledge of the “cheyenneandliberty” account or
    the explicit images on his phone other than the ones of his youngest daughter.
    Kearn operated a heating and air conditioning business from his home, and
    suggested a former employee with access to his iPhone could have downloaded
    the images and e-mailed them to Detective Butler.
    Kearn also presented evidence from his own computer expert, Andreux
    Doty. Doty testified he found only an isolated reference to “cheyenneandliberty”
    in a file created from the iPhone data. He testified he did not find any evidence
    in government materials he reviewed that the “cheyenneandliberty” e-mails had
    been sent from Kearn’s phone.
    The jury found Kearn guilty on all counts. The district court sentenced
    Kearn to 292 months in prison followed by five years of supervised release,
    during which he may not contact minors or the victim of the offense (his youngest
    daughter).
    -6-
    II. Analysis
    Kearn raises a number of issues on appeal. He argues various evidence
    introduced at trial was inadmissible on hearsay or relevancy grounds, and that the
    admission of the hearsay evidence violated his Confrontation Clause rights. He
    also contends the court should have instructed the jury to agree unanimously on
    which specific images were the basis for his conviction. He urges us to find these
    errors cumulatively mandate relief. And he submits that a supervised-release
    condition that will prohibit him from contacting his victim—his youngest
    daughter—was improper. 1
    Kearn did not raise these issues at trial, so we review them for plain error.
    “Under the plain error standard, [the appellant] must demonstrate: (1) an error,
    (2) that is plain, meaning clear or obvious under current law, (3) that affects
    1
    We do not address in detail two other issues Kearn raises. First, Kearn
    challenges the constitutionality of the Tenth Circuit reasonable-doubt instructions
    given at his trial, but we have recently upheld the constitutionality of those
    instructions. See United States v. Petty, 
    856 F.3d 1306
    , 1311 (10th Cir. 2017)
    (concluding that the Tenth Circuit Pattern Jury Instruction on reasonable doubt,
    “taken as a whole, adequately convey[s] the concept of reasonable doubt to the
    jury”).
    Second, Kearn argues that if we do not find plain error, we should remand
    to the district court for an evidentiary hearing on claims of ineffective assistance
    of counsel. But our decision in United States v. Galloway, 
    56 F.3d 1239
    (10th
    Cir. 1995) (en banc) forecloses that approach. See 
    id. at 1240
    (“Ineffective
    assistance of counsel claims should be brought in collateral proceedings, not on
    direct appeal. Such claims brought on direct appeal are presumptively
    dismissible, and virtually all will be dismissed.”).
    -7-
    substantial rights, and (4) that seriously affects the fairness, integrity, or public
    reputation of judicial proceedings.” United States v. Piper, 
    839 F.3d 1261
    ,
    1265–66 (10th Cir. 2016) (citing United States v. Rosales-Miranda, 
    755 F.3d 1253
    , 1257–58 (10th Cir. 2014)). Crucially, “[t]o satisfy the third prong of
    plain-error review, a defendant generally must demonstrate that an error was
    ‘prejudicial, meaning that there is a reasonable probability that, but for the error
    claimed, the result of the proceeding would have been different.’” United States
    v. Bustamante-Conchas, 
    850 F.3d 1130
    , 1138 (10th Cir. 2017) (en banc) (quoting
    United States v. Algarate-Valencia, 
    550 F.3d 1238
    , 1242 (10th Cir. 2008)).
    We review each of the issues raised in turn, and find no plain error as to
    any.
    A. Hearsay Testimony
    Kearn first contends the district court improperly admitted hearsay
    evidence through his expert witness. At trial, Kearn presented the testimony of
    computer expert Andreux Doty, who testified he did not find any evidence the
    “cheyenneandliberty” e-mails were sent from Kearn’s phone. On
    cross-examination, the government asked Doty what documents he had reviewed.
    As part of this line of inquiry, the government asked about a report prepared by a
    previously retained defense expert, Tammy Loehrs. Loehrs did not testify at trial.
    After Doty said he had read the Loehrs Report, the prosecutor asked him if “it
    would help [his] memory if [she] showed [him] a copy” of the report. R., Vol. 2
    -8-
    at 718. When he said yes, she showed him the report, which was marked as a
    Government Exhibit.
    The Loehrs Report, even though solicited by the defense, was substantially
    more inculpatory than Doty’s report. The prosecution asked Doty whether Loehrs
    “did a key word search for cheyenneandliberty . . . [that] resulted in over 1,000
    hits located in numerous folders on . . . both the phone and the hard drive[.]” R.,
    Vol. 2 at 726–27. The prosecution also asked whether the Loehrs Report located
    “45 hits” for the term ProudPapa—used in the e-mails with Detective Butler—on
    Kearn’s iPhone. R., Vol. 2 at 727. Doty said the Loehrs Report asserted both
    those points. On redirect, Kearn’s lawyer asked Doty more questions about the
    Loehrs Report, and Doty criticized the Loehrs Report for failing to “validate” the
    more-than-one-thousand hits for “cheyenneandliberty” in the report, and for
    indicating that files on the computer had been accessed after the computer had
    been taken into custody. R., Vol. 2 at 739–41.
    Kearn contends that eliciting the contents of the Loehrs Report from Doty
    violated Federal Rule of Evidence 802, which generally prohibits the admission of
    hearsay evidence, as well as the Confrontation Clause of the Sixth Amendment.
    Assuming without deciding that the Loehrs Report was hearsay and
    violated Kearn’s rights under the Confrontation Clause, Kearn cannot demonstrate
    that the district court plainly erred by admitting it. “To satisfy the third prong of
    plain-error review, a defendant generally must demonstrate that an error was
    -9-
    ‘prejudicial, meaning that there is a reasonable probability that, but for the error
    claimed, the result of the proceeding would have been different.’”
    
    Bustamante-Conchas, 850 F.3d at 1138
    (quoting United States v.
    Algarate-Valencia, 
    550 F.3d 1238
    , 1242 (10th Cir. 2008)). Kearn cannot do that
    here. 2
    The prosecution’s colloquy with Doty regarding the Loehrs Report is
    relatively short. The facts elicited about the report from Doty were: (1) “there
    2
    Kearn argues that under the third prong of plain-error analysis “prejudice
    for purposes of a Confrontation Clause violation focuses ‘on the particular
    witness, not on the outcome of the entire trial.’” Aplt. Br. at 27 (quoting United
    States v. Holloway, 
    826 F.3d 1237
    , 1249 (10th Cir. 2016)). But this conflates the
    prejudice requirement in the third prong of plain-error analysis with the showing
    of prejudice required to state a violation of the Confrontation Clause. Although
    the word “prejudice” appears in both contexts, the cases are not referring to the
    same inquiry.
    It is true that in order to state a violation of the Confrontation Clause, a
    defendant need only make a showing of prejudice as to a particular witness, not as
    to the trial as a whole. See, e.g., 
    Holloway, 826 F.3d at 1249
    . But the third prong
    of plain-error analysis is not where we address whether there has been a violation
    of the Confrontation Clause. Rather, it is at the first prong of plain-error analysis,
    when we ask whether there is error, that we look to whether there is a violation of
    the Confrontation Clause—and therefore, whether there is prejudice as to a
    particular witness.
    Here, then, because we assume error and decide the issue on the third
    prong, we ask not whether there has been a violation of the Confrontation Clause,
    but instead make the normal inquiry: whether there is a reasonable probability
    that, but for the error claimed, the result of the proceeding would have been
    different. See, e.g., United States v. Pablo, 
    696 F.3d 1280
    , 1293–94 (10th Cir.
    2012) (finding that an assumed Confrontation Clause violation did not affect a
    defendant’s substantial rights where the defendant would have been convicted
    even without the erroneous testimony).
    -10-
    was an application on [Kearn’s] phone that was for storing a photograph,” R.,
    Vol. 2 at 725; (2) “the Loehrs[] examination also determined that the [e]-mail
    cheyenneandliberty[] was being used on the iPhone with other accounts but
    [Loehrs] was unable to recover any actual [e]-mails,” R., Vol. 2 at 726; (3) “a key
    word search for cheyenneandliberty . . . resulted in over 1,000 hits . . . [on] both
    the phone and the [personal computer] hard drive,” R., Vol. 2 at 726–27; and
    (4) Loehrs found 45 hits for “ProudPapa” on the iPhone, R., Vol. 2 at 727.
    Most of these points came out in the properly admitted non-hearsay
    testimony of the prosecution’s expert witness, Agent Beebe. See R., Vol. 2
    at 565–66 (password-protected application on phone for storing photographs
    contained possible child pornography); R., Vol. 2 at 564–65 (examination
    revealed that the “cheyenneandliberty” e-mail address was being used on the
    phone); R., Vol. 2 at 580–81 (search results for “cheyenneandliberty” and
    “ProudPapa”). The only distinction is that Special Agent Beebe did not number
    the hits for “cheyenneandliberty” “over 1,000,” but that distinction is immaterial
    in context.
    For instance, Kearn admitted taking the explicit pictures and videos. The
    pictures were e-mailed using an IP address associated with Kearn’s house. The
    embedded data showed the pictures were taken shortly before they were e-mailed,
    which was a year after Kearn claimed his daughter had been molested. The home
    security system showed Kearn using his phone around the time the e-mails were
    -11-
    sent. Kearn’s phone contained evidence of the e-mail address from which the
    pictures were sent. Finally, Kearn’s phone contained other explicit photographs
    of children.
    Because the information elicited about the Loehrs Report did not affect the
    outcome of the trial, we find the district court did not commit plain error by
    admitting it.
    B. Helpfulness of Testimony
    Kearn next argues several statements by government witnesses violated
    Federal Rules of Evidence 701 and 702, which provide that opinion testimony
    must be helpful to the trier of fact to be admissible. See Fed. R. Evid. 701(b) (“If
    a witness is not testifying as an expert, testimony in the form of an opinion is
    limited to one that is . . . helpful to clearly understanding the witness’s testimony
    or to determining a fact in issue.”); 
    id. 702(a) (“A
    witness who is qualified as an
    expert by knowledge, skill, experience, training, or education may testify in the
    form of an opinion or otherwise if . . . the 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.”).
    He contends two prosecution witnesses improperly testified that certain
    images qualified as child pornography. In Kearn’s view, these statements were
    -12-
    inadmissible because they were not helpful to the jury. 3 For example, at trial the
    government asked Agent Beebe whether he prepared a report of his findings from
    searching Kearn’s phone. He answered: “Yes. In my preview I reported that I
    saw images that were child pornographic in nature.” R., Vol. 2 at 557. Later the
    government asked Agent Beebe whether he found “images that [he] believed were
    child pornography on the iPhone.” He responded yes. R., Vol. 2 at 566.
    Rule 701 applies to the lay testimony of Detective Butler and Agent
    Casner, and Rule 702 applies to the expert testimony of Agent Beebe. But
    “helpfulness” is similar for both lay and expert testimony. Testimony is not
    helpful if it “simply tell[s] the jury what result it should reach without providing
    any explanation of the criteria on which that opinion is based or any means by
    which the jury can exercise independent judgment.” United States v. Dazey, 
    403 F.3d 1147
    , 1171 (10th Cir. 2005). We have excluded this type of testimony
    because “it usurps the function of the jury in deciding the facts,” or because it
    “interferes with the function of the judge in instructing the jury on the law.” 
    Id. at 1171
    (internal quotation marks omitted).
    3
    Kearn also argues that testimony he distributed the images to Detective
    Butler and that he owned the iPhone on which the images were recovered violated
    these rules. But these are facts, not opinions, so these rules do not apply.
    In addition, Kearn cites Rule 704(b), which prohibits experts from
    testifying “about whether the defendant did or did not have a mental state or
    condition that constitutes an element of the crime charged or of a defense.” But
    none of the statements Kearn cites opine on his mental state or knowledge: that is,
    whether he possessed, produced, or disseminated the images knowingly.
    -13-
    In support of his argument that the testimony identifying child pornography
    was not helpful, Kearn points to a Seventh Circuit case, which found inadmissible
    a federal agent’s testimony that photos on the defendant’s computer met the
    federal definition of child pornography. United States v. Noel, 
    581 F.3d 490
    ,
    496–99 (7th Cir. 2009). The Noel court found that the agent’s testimony was
    “[l]ay testimony offering a legal conclusion” and thus “inadmissible because it
    [was] not helpful to the jury.” 
    Id. at 496.
    But the witness comments here are distinguishable from the comments in
    Noel, because these witnesses did not mention the legal definition, or tell the jury
    what to find. Indeed, the government made clear its questions did not concern the
    legal definition of child pornography. See R., Vol. 2 at 437–38.
    We resolved a similar question in United States v. Stanley, 
    896 F.2d 450
    ,
    451–52 (10th Cir. 1990). In Stanley, a U.S. Postal Inspector testified that he had
    “specialized in the investigation of prohibited mailings such as child
    pornography” for decades. 
    Id. at 451.
    The government offered as lay opinion
    testimony the inspector’s opinion that “several of the children depicted in
    sexually explicit conduct were under the age of eighteen.” 
    Id. at 451–52.
    On
    appeal, the defendant argued this testimony was not helpful because the pictures
    “spoke for themselves.” 
    Id. at 452.
    This court disagreed, finding that the
    inspector’s testimony was helpful (1) “in determining the age of the subjects,”
    which was “a fact in issue;” and (2) “as an explanation of why he ordered a
    -14-
    supervised delivery, obtained a search warrant, and seized the defendant’s
    package.” 
    Id. at 452.
    The same analysis holds here. Testimony about whether particular images
    were child pornography was helpful to the jury, since whether the images
    depicted “sexually explicit conduct” was a fact in issue. See R., Vol. 1 at 23–25
    (the indictment, citing 18 U.S.C. §§ 2251(b), 2252(a)(2), 2252(a)(4)(B)). And
    testimony about the law-enforcement officers’ views on the images was helpful as
    an explanation of why they took certain steps in their investigation.
    We therefore do not find the district court plainly erred by admitting this
    testimony.
    C. Rule 404(b) Evidence—Prior Similar Acts
    The government filed a pre-trial motion to introduce evidence “located on
    the defendant’s smart phone and computer, including but not limited to sexually
    explicit images of any minors, nude video clips of [Kearn’s youngest daughter],
    and search terms indicating an interest in such material.” R., Vol. 1 at 74. The
    government sought to introduce the evidence under Rule 404(b) to show “the
    defendant’s intent, knowledge, absence of mistake and lack of accident.” 
    Id. Kearn argues
    this was error, because the government did not “precisely articulate
    the purpose of the proffered evidence.” Aplt. Br. at 41 (citing United States v.
    Birch, 
    39 F.3d 1089
    , 1093 (10th Cir. 1994)).
    -15-
    Under Rule 404(b), “[e]vidence of a crime, wrong, or other act is not
    admissible to prove a person’s character in order to show that on a particular
    occasion the person acted in accordance with the character.” Fed. R. Evid.
    404(b). It may, however, “be admissible for another purpose, such as proving
    motive, opportunity, intent, preparation, plan, knowledge, identity, absence of
    mistake, or lack of accident.” 
    Id. The prosecutor
    must provide notice if he
    intends to offer such evidence at trial. 
    Id. We have
    held that “the government must precisely articulate the purpose of
    the proffered [404(b)] evidence.” United States v. Birch, 
    39 F.3d 1089
    , 1093
    (10th Cir. 1994). Moreover, the trial court must “specifically identify the purpose
    for which such evidence is offered.” 
    Id. (quoting United
    States v. Kendall, 
    766 F.2d 1426
    , 1436 (10th Cir. 1985)). “[A] broad statement merely invoking or
    restating Rule 404(b) will not suffice.” 
    Id. (quoting Kendall,
    766 F.2d at 1436).
    We have therefore held that a statement providing that the evidence’s purpose was
    “to prove the defendant’s knowledge, identity and absence of mistake or accident”
    “failed to articulate with precision the evidentiary purpose of the Rule 404(b)
    evidence it offered.” 
    Id. The broad
    statement offered by the government in its pre-trial motion
    tracks almost exactly the statement we found inadequate in Birch. But the
    government responds that the district court here never ruled on the pre-trial Rule
    404(b) motion. In its view, the evidence at trial was intrinsic to the charged
    -16-
    conduct, and was not admitted under Rule 404(b). The government’s brief
    canvasses the evidence, and explains the purpose for which each piece was
    admitted—making out the elements of the charged offenses. Because Kearn was
    on trial for knowingly distributing and possessing child pornography, sexually
    explicit images on his phone and search terms indicating his mental state did not
    need to come into trial under 404(b). They were the very point of the trial.
    Kearn does not point us to the district court’s ruling on the proposed
    evidence, and does not dispute the government’s assertion that the evidence at
    trial did not come in under Rule 404(b). There are no references to Rule 404(b)
    in the trial record, other than the government’s motion.
    Kearn, moreover, does not point to any evidence actually admitted under
    Rule 404(b), and does not rebut the government’s argument that none was. Given
    that, we cannot find that the district court erred here.
    D. Instruction on Unanimity of Theory
    Kearn next argues the district court erred in failing to instruct the jury that
    it must agree unanimously on which specific images were the basis for
    conviction. The district court only gave a general unanimity instruction. R., Vol.
    1 at 217 (“Your verdict on each count of the Indictment must be unanimous.”).
    Kearn argues this instruction was insufficient, and Tenth Circuit Criminal Pattern
    Jury Instruction § 1.24, at 37 (2011 ed., rev. 2017) (“Unanimity of Theory”) was
    legally required. The relevant part of that instruction provides that “in order to
    -17-
    return a guilty verdict, all twelve of you must agree upon which of the listed acts,
    if any, the defendant committed.” Since, argues Kearn, there were multiple
    images that arguably violated federal law, different jurors could have had in mind
    different images when finding Kearn guilty.
    We disagree that Instruction § 1.24 was required. Its use note explains that
    Instruction § 1.24 “should be used when the government introduces evidence
    that the defendant has committed multiple acts which may constitute an
    element of the crime.” 
    Id. (emphasis added).
    Instruction § 1.24 is a response to
    Richardson v. United States, 
    526 U.S. 813
    (1999), which involved different
    statutory language than the language relevant to Kearn’s conviction.
    Richardson involved a conviction under 21 U.S.C. § 848(a), which
    prohibits persons from “engag[ing] in a continuing criminal enterprise,” defined
    by the statute as a “‘violat[ion]’ of the drug statutes where ‘such violation is part
    of a continuing series of violations.’” 
    Id. at 815
    (quoting 21 U.S.C. § 848(a),
    (c)). The Supreme Court held that “a jury in a federal criminal case brought
    under § 848 must unanimously agree not only that the defendant committed some
    ‘continuing series of violations’ but also that the defendant committed each of the
    individual ‘violations’ necessary to make up that ‘continuing series.’” 
    Id. (quoting 21
    U.S.C. § 848(a), (c)).
    Richardson based its holding on a distinction between the elements of an
    offense and the means by which the government may satisfy an element.
    -18-
    Elements, the Court held, must be found unanimously by the jury. 
    Id. at 817.
    On
    the other hand, the jury need not agree unanimously on the means by which an
    element is proven. 
    Id. Consequently, “a
    federal jury need not always decide
    unanimously which of several possible sets of underlying brute facts make up a
    particular element, say, which of several possible means the defendant used to
    commit an element of the crime.” 
    Id. Instruction §
    1.24 applies to situations like the one in Richardson, where
    the government produces evidence the defendant has committed multiple acts that
    might be considered elements of the crime. See United States v. Sorensen, 
    801 F.3d 1217
    , 1237 (10th Cir. 2015) (describing Instruction § 1.24 as “anchored in
    Richardson’s holding” and finding fault in its use in a charge “far different from
    Richardson”), cert. denied, 
    136 S. Ct. 1163
    (2016). It does not apply to situations
    where multiple acts might be considered different means of satisfying the element
    requirement. 
    Id. Looking at
    the statutes under which Kearn was charged and convicted, we
    find they do not require unanimity as to which images formed the basis for
    conviction. Different images are merely different means of satisfying the element
    requirement, not different statutory elements.
    Kearn was convicted of three offenses: violations of 18 U.S.C. § 2251(b),
    18 U.S.C. § 2252(a)(2), and 18 U.S.C. § 2252(a)(4)(B). Stripped to the relevant
    language, we have:
    -19-
    •     “Any parent . . . who knowingly permits such minor to engage in . . .
    sexually explicit conduct for the purpose of producing any visual depiction
    of such conduct . . . shall be punished . . . [if the depiction travels in
    interstate commerce.]” 18 U.S.C. § 2251(b) (emphasis added).
    •     “Any person who . . . knowingly receives, or distributes, any visual
    depiction [in interstate commerce] . . . if—(A) the producing of such visual
    depiction involves the use of a minor engaging in sexually explicit conduct;
    and (B) such visual depiction is of such conduct . . . shall be
    punished . . . .” 18 U.S.C. § 2252(a)(2) (emphasis added).
    •     “Any person who . . . knowingly possesses . . . 1 or more [media] . . .
    which contain any visual depiction that has [traveled in interstate
    commerce] . . . if—(i) the producing of such visual depiction involves the
    use of a minor engaging in sexually explicit conduct; and (ii) such visual
    depiction is of such conduct; shall be punished . . . .” 18 U.S.C. §
    2252(a)(4)(B).
    All three statutes thus refer to “any visual depiction” meeting the statutory
    criteria. In other words, if the government has shown the jury that the defendant
    has produced (§ 2251(b)), distributed (§ 2252(a)(2)), or possessed (§ 2252(a)(4))
    any visual depictions of minors engaged in sexually explicit conduct, the jury
    may convict. The government’s evidence thus went to means of satisfying the
    statutory language, rather than different possible elements. Richardson and
    Instruction § 1.24 therefore have no application here.
    An example may clarify this interpretation. Suppose a statute makes the
    following conduct illegal: “The murdering of another in the room of a house with
    a blunt household instrument.” This statute thus has three elements: (1) “the
    murdering of another” (2) “in the room of a house” (3) “with a blunt household
    instrument.” The evidence at trial is that Peter and Paul were in a house alone
    -20-
    together, all entrances and exits to the house were locked, and Paul died from
    head trauma from a blunt instrument. Peter’s fingerprints and DNA were found
    on a candlestick, a wrench, and a lead pipe in the house, but it is not clear which
    was the murder weapon. It is also unclear where in the house the murder
    occurred. Under Kearn’s theory of the law, the jury cannot convict unless they
    unanimously agree on the murder weapon and the room where the murder
    occurred. But the holding of Richardson sets a lower bar than the rules of
    “Clue.” The jury need only unanimously agree that (1) Peter murdered Paul,
    (2) in the room of a house, (3) with a blunt household instrument. If the evidence
    at trial persuades them of those elements, they may convict. They need not agree
    unanimously on which room and weapon; the different weapons and rooms are
    merely means of satisfying the statutory elements. If six jurors are persuaded it
    happened in the library with a candlestick, and six jurors think it happened in the
    observatory with a lead pipe, that would not vitiate the conviction. So too here.
    Because unanimity as to which images formed the basis for conviction is
    not required, we do not find the district court erred.
    E. Cumulative Error
    Kearn argues the cumulative effect of the district court’s errors rendered
    his trial fundamentally unfair.
    “A cumulative-error analysis aggregates all errors found to be harmless and
    analyzes whether their cumulative effect on the outcome of the trial is such that
    -21-
    collectively they can no longer be determined to be harmless.” United States v.
    Toles, 
    297 F.3d 959
    , 972 (10th Cir. 2002). We have explained above why most of
    Kearn’s putative errors were not, in fact, errors. Kearn adds two more errors in
    the cumulative-error section of his brief.
    First, he argues that the district court erred by allowing government
    witnesses to provide expert testimony without satisfying the expert witness
    disclosure requirement. In his view, once the government established that Agent
    Casner and Detective Butler were trained to recognize child pornography, their
    testimony that certain images were child pornography was expert testimony. But
    we are not persuaded. Rule 701 “does not permit a lay witness to express an
    opinion as to matters which are beyond the realm of common experience and
    which require the special skill and knowledge of an expert witness.” Randolph v.
    Collectramatic, Inc., 
    590 F.2d 844
    , 846 (10th Cir. 1979). But “Rule 701 allows
    lay witnesses to offer ‘observations [that] are common enough and require . . . a
    limited amount of expertise, if any.’” James River Ins. Co. v. Rapid Funding,
    LLC, 
    658 F.3d 1207
    , 1214 (10th Cir. 2011). The testimony here—that child
    pornography involves sexually explicit imagery of children, and that certain
    explicit images qualified—did not go beyond the realm of common experience.
    They therefore did not constitute expert testimony.
    Second, Kearn argues that Detective Butler’s statement that
    “cheyenneandliberty” was a “contact child sex offender” was irrelevant and
    -22-
    prejudicial. R., Vol. 2 at 406. To put this statement in context, the prosecutor
    asked Detective Butler: “What else did you do as part of your investigation?” R.,
    Vol. 2 at 406. He responded: “As soon as I received even the first couple of
    images I was very alarmed by it and realized this guy was a contact sex offender
    and immediate action had to be taken, so I contacted Homeland Security
    Investigations in the USA and I referred the matter straight away.” 
    Id. Evidence is
    relevant if “(a) it has any tendency to make a fact more or less
    probable than it would be without the evidence; and (b) the fact is of consequence
    in determining the action.” Fed. R. Evid. 401. This portion of the testimony,
    taken as a whole, made it more probable that Kearn produced and distributed
    sexually explicit images through interstate commerce. That fact is of
    consequence, since it forms the basis of two of the three charges of the
    indictment. It is plainly relevant.
    Nor was it prejudicial. Under Federal Rule of Evidence 403, “[t]he court
    may exclude relevant evidence if its probative value is substantially outweighed
    by a danger of . . . unfair prejudice.” The supposed unfair prejudice here was in
    implying that Kearn was a contact sex offender. But the government’s entire
    theory of the case was that Kearn was a contact sex offender. Any prejudice
    added by Detective Butler’s statement was therefore minimal.
    Because this statement violated neither Rule 401 or 403, there was no error.
    -23-
    Thus, the only possible error we have identified is the admission of the
    hearsay evidence from the Loehrs Report. But “[t]he purpose of cumulative error
    analysis is to address whether the cumulative effect of two or more individually
    harmless errors has the potential to prejudice a defendant to the same extent as a
    single reversible error.” United States v. Rogers, 
    556 F.3d 1130
    , 1144 (10th Cir.
    2009) (emphasis added) (internal quotation marks omitted). Because we have not
    found multiple errors, cumulative error analysis is unavailing here. Moreover, as
    noted, the evidence of Kearn’s guilt was overwhelming, and we doubt, even
    absent any of Kearn’s alleged errors, the outcome of the trial would have been
    different.
    F. Supervised-Release Condition
    The district court sentenced Kearn to five years of supervised release
    following his term of imprisonment. One of the special conditions of his
    supervised release is that he may have no contact with the victim of the offense,
    i.e., his youngest daughter. Kearn has a 292-month (24 1/3 year) sentence, so his
    youngest daughter will be over 30 years old by the time Kearn is released from
    prison. Kearn objects to this condition, arguing the district court abused its
    discretion by imposing it.
    Kearn provides two reasons why this condition was improper. First, the
    condition is not “reasonably related” to the offense of conviction, as the statute
    requires. See 18 U.S.C. § 3583(d)(1). Second, he has a “fundamental right of
    -24-
    familial association,” and the district court did not have the requisite
    “compelling” reason for interfering with this right. Aplt. Br. at 49 (quoting
    United States v. Lonjose, 
    663 F.3d 1292
    , 1303 (10th Cir. 2011)).
    But Kearn has waived this issue by failing to argue for plain error. Neither
    of these arguments—reasonable relationship or familial association—was raised
    at sentencing. See R., Vol. 2 at 885–87 (relevant portion of the sentencing
    colloquy). Generally, “the failure to argue for plain error and its application on
    appeal . . . marks the end of the road for an argument for reversal not first
    presented to the district court.” Richison v. Ernest Grp., Inc., 
    634 F.3d 1123
    ,
    1131 (10th Cir. 2011).
    We therefore affirm the no-contact-with-victims condition. Kearn’s failure
    to argue these points under the plain-error standard marks the end of the road. 4
    III. Conclusion
    For the reasons above, we AFFIRM the judgment and sentence of the
    district court and DISMISS without prejudice Kearn’s claim of ineffective
    assistance of counsel.
    4
    It is worth noting that, like any special condition, the defendant can
    petition the court based on changed circumstances at the time of his release.
