    Before BRISCOE, Chief Judge, McKAY and GORSUCH, Circuit Judges.
    GORSUCH, Circuit Judge.
    For Rebecca Christie, life must have seemed more virtual than real. She
    usually awoke around noon, settled in before her computer, and logged on to
    World of Warcraft for gaming sessions lasting well past midnight. There she
    assumed a new identity in a fantastical world filled with dragons and demons
    where players staged heroic adventures with and against other players. All the
    while back in the real world Ms. Christie ignored the needs of her three-year-old
    daughter. The neglect didn’t prove fatal so long as Ms. Christie’s husband was
    around to provide some care. But nine days after her husband left for an out-of-
    state deployment, the child was dead from dehydration.
    Appealing second-degree murder and child abuse convictions, Ms. Christie
    raises significant questions about computer searches under the Fourth Amendment
    and the exclusion of witnesses from trial under the Sixth Amendment. The
    government’s cross-appeal raises important questions, too, touching on the
    Assimilative Crimes Act and the Fifth Amendment’s double jeopardy guarantee.
    In the end, however, we think the district court handled all these questions well
    and carefully and we see no grounds on which we might reverse its judgment in
    this tragic case.
    I
    Ms. Christie’s child began life a healthy baby girl. But by twenty-one
    months, something appeared badly wrong. She plummeted to the bottom fifth
    percentile in weight for her age and began suffering from chronic diarrhea. A
    -2-
    pediatrician prescribed PediaSure, a nutritional drink that helps children gain
    weight. That seemed to do the trick: the diarrhea soon stopped and BW (the
    district court and parties refer to the child by her initials) began gaining weight.
    By all appearances, she had turned a corner.
    But even the best cure won’t work if it isn’t administered. And it seems
    Ms. Christie and her then-husband Derek Wulf, himself a zealous gamer, weren’t
    up to the job. For her part, Ms. Christie would put BW to bed each night around
    10 p.m., shut BW’s door, and failed to retrieve the child until noon or later the
    following day. Because BW couldn’t open the door herself, Ms. Christie
    effectively locked the child away without food or water for fourteen or more
    hours a day. Even when BW was free to seek food and water it appears little was
    available to her. Ms. Christie let slip to investigators that the child was always
    hungry and would sometimes try to eat the food she left out for the family cats.
    Ms. Christie’s step-daughter (who visited on occasion) testified that Ms. Christie
    often wouldn’t feed her or BW until noon and that BW’s obvious hunger drove
    her to share her own food with BW.
    Eventually, Mr. Wulf faced a deployment on the other side of the country.
    With the little care he provided BW now gone with him and the child’s fate
    entirely in Ms. Christie’s hands, the child was in trouble. Already badly
    malnourished, she succumbed to dehydration in nine days. An autopsy revealed
    that no inborn disorder was to blame. BW simply died from being ignored.
    -3-
    Medical experts testified that BW’s desperate condition in the days before
    her death would have been blindingly clear. BW would have sought out water as
    a survival instinct. When that failed, she would have become lethargic and, on
    the day before her death, too weak to move. Her diapers wouldn’t have needed
    changing. She would have had sticky saliva and then no saliva at all. She would
    have developed cracked lips, sunken eyes, and a sunken abdomen.
    First responders confirmed that this is exactly what they saw when they
    found the child. They testified that BW’s lips were cracked and blue, her eyes
    glassy, and her eyelids so dry they couldn’t close. They said bones protruded
    from her body and her gums had turned black.
    Because BW died on an Air Force base, federal authorities bore the
    responsibility to investigate and the power to prosecute. They proceeded against
    Ms. Christie and Mr. Wulf separately. In our proceeding, a federal jury found
    Ms. Christie guilty of second-degree murder, two assimilated state law homicide
    charges, as well as an assimilated child abuse charge. After trial, the district
    court dismissed the two assimilated homicide charges and entered a twenty-five
    year sentence on the remaining second-degree federal murder and the assimilated
    child abuse charge.
    It is this judgment both sides now appeal.

    II
    Much of the evidence presented at trial against Ms. Christie came from the
    computer she so prized. From their forensic analysis, FBI investigators learned
    that Ms. Christie’s online activities usually kept her busy from noon to 3 a.m.
    with little pause. They learned that she was in a chat room only an hour before
    finding BW near death, and that she was back online soon afterwards. They
    learned from Ms. Christie’s messages to other gamers that she was annoyed by
    her responsibilities as a mother and “want[ed] out of this house fast.” When Mr.
    Wulf was slated for deployment, she announced to online friends that she would
    soon be free to “effing party.”
    Ms. Christie contends this evidence and more from her computer was
    uncovered in violation of her Fourth Amendment rights and the district court
    should have suppressed it from her trial. Because the court didn’t, because it
    admitted the proof against her, Ms. Christie says a new trial is required. To be
    precise, Ms. Christie doesn’t question whether the government’s seizure of the
    computer satisfied the Fourth Amendment. The government took possession of
    the computer in May 2006 with Mr. Wulf’s consent. Everyone accepts that he
    was at least a co-owner of the computer — it was a gift from his father — and
    everyone accepts he had at least apparent authority to relinquish its control.
    Instead, Ms. Christie attacks the propriety of the two searches the government
    undertook once it had control of the computer. To justify its searches the
    -5-
    government does not seek to rely on Mr. Wulf’s consent but points to a pair of
    warrants it sought and received, one for each search. It is these warrants Ms.
    Christie challenges, arguing they were issued in defiance of the Fourth
    Amendment.
    A
    The first warrant came in October 2006, some five months after authorities
    seized the computer. Ms. Christie argues this investigative delay — between
    seizure and search — was constitutionally impermissible, should have precluded
    any warrant from issuing, and itself requires the suppression of everything the
    government found.
    We do not doubt that an unreasonable delay in obtaining a search warrant
    can sometimes violate the Fourth Amendment. This much surely flows from the
    Fourth Amendment’s guarantee against “unreasonable searches and seizures.”
    U.S. Const. amend. IV. What, after all, is “reasonable” about police seizing an
    individual’s property on the ground that it potentially contains relevant evidence
    and then simply neglecting for months or years to search that property to
    determine whether it really does hold relevant evidence needed for trial or is
    totally irrelevant to the investigation and should be returned to its rightful owner?
    See, e.g., United States v. Burgard, 
    675 F.3d 1029
    , 1033 (7th Cir. 2012); United
    States v. Laist, 
    702 F.3d 608
    , 613-14 (11th Cir. 2012); United States v. Martin,
    -6-
    
    157 F.3d 46
    , 54 (2d Cir. 1998); United States v. Respress, 
    9 F.3d 483
    , 488 (6th
    Cir. 1993).
    In assessing the reasonableness of a delay in seeking a warrant, however,
    we must take account of “the totality of the circumstances” in each case as it
    comes to us, United States v. Sokolow, 
    490 U.S. 1
    , 8 (1989), wary of the
    temptation to impose “rigid rules, bright-line tests, and mechanistic inquiries,”
    Florida v. Harris, 
    133 S. Ct. 1050
    , 1055 (2013). What reasonably justifies a brief
    delay, for example, may not reasonably justify a longer one. Our task in each
    case is to “balance the nature and quality of the intrusion on the individual’s
    Fourth Amendment interests against the importance of the governmental interests
    alleged to justify the intrusion.” United States v. Place, 
    462 U.S. 696
    , 703
    (1983).
    Looking first to Ms. Christie’s side of the ledger, it’s hard to see a
    significant invasion of her Fourth Amendment interests flowing from the
    government’s delay. That’s not to say she never had an interest in the computer.
    Far from it. She was its primary user and she stored a great deal of personal data
    on the computer. We don’t question that is enough to establish some possessory
    and privacy interest in the computer the Fourth Amendment would recognize and
    protect. See United States v. Jacobsen, 
    466 U.S. 109
    , 113 (1984); United States
    v. Angevine, 
    281 F.3d 1130
    , 1133-34 (10th Cir. 2002).
    -7-
    The difficulty Ms. Christie faces comes from her husband’s actions and her
    own inactions. The fact is Mr. Wulf was at least a co-owner of the computer, he
    consented to its seizure, and Ms. Christie herself raised no objection to the
    seizure either at the time or in the following weeks and months. No call to the
    authorities, no letter, no motion to the court. Put differently, one individual with
    common and at least apparent authority over the computer freely gave it to
    authorities and the other individual never objected. In these circumstances, the
    government was entitled to assume under long-standing Supreme Court teachings
    that any Fourth Amendment interest in the computer’s continued possession had
    been voluntarily relinquished. See, e.g., United States v. Matlock, 
    415 U.S. 164
    ,
    171 (1974); United States v. Andrus, 
    483 F.3d 711
    , 716-20 (10th Cir. 2007). 1
    These features of our case also distinguish it from the primary case on
    which Ms. Christie relies: United States v. Mitchell, 
    565 F.3d 1347
     (11th Cir.
    2009). There, officers seized a computer without the consent of the (only) owner
    and, in doing so, at least presumptively impaired his possessory interest in it. 
    Id.
    1
    Ms. Christie says she did object to the seizure. But the district court
    found otherwise and that factual finding can only be overturned if clearly
    erroneous. See United States v. Ludwig, 
    641 F.3d 1243
    , 1247 (10th Cir. 2011).
    Seeking to meet that demanding standard, Ms. Christie stresses that, after Mr.
    Wulf consented to the computer’s seizure, she asked for copies of schoolwork she
    had stored on the computer — a request that, by all accounts, FBI Special Agent
    Chad Oakes refused. But this fact does not compel the inference Ms. Christie
    wanted the computer itself or objected to Mr. Wulf’s decision to give it to the
    authorities. In fact, during their conversation Agent Oakes told Ms. Christie he
    had already obtained Mr. Wulf’s permission for the seizure and Ms. Christie
    offered no objection in response.
    -8-
    at 1349-50. But when a computer is seized with a co-owner’s consent and no one
    else bearing a potential interest in the computer complains about the resulting
    delay, the degree of prejudice appears in an altogether different — and paler —
    light. See United States v. Johns, 
    469 U.S. 478
    , 487 (1985) (defendants who
    “never sought return of the property” failed to identify how “the delay in the
    search . . . adversely affected legitimate interests protected by the Fourth
    Amendment”); United States v. Stabile, 
    633 F.3d 219
    , 235-36 (3d Cir. 2011)
    (distinguishing Mitchell on the same grounds as we do); United States v. Burgess,
    
    576 F.3d 1078
    , 1097 (10th Cir. 2009).
    Shifting to the other side of the ledger, the government makes out at least a
    colorable case for holding onto the computer so long before undertaking a search.
    The agent who seized the computer and later searched it says that in between he
    was called upon to help with out-of-town undercover operations in other cases.
    No one before us disputes the existence of these operations. No one questions
    that they amounted to a higher law enforcement priority than the computer search
    in this case. Neither has Ms. Christie (who bears the burden of proof on her
    motion to suppress) developed evidence suggesting her case or the others could
    have been transferred to another available agent. In these circumstances, we
    hesitate to say the government lacked any colorable grounds for its delay.
    Having set out the parties’ competing (maybe incommensurable) interests,
    we must now try to “balance” or “weigh” them. As we see it, the government’s
    -9-
    side of the ledger reveals a colorable interest in prioritizing law enforcement
    efforts while Ms. Christie can point to little harm to her interests in light of her
    husband’s express consent and her lack of objection. Given this, we hold the
    delay in our case falls inside the bounds of constitutionally reasonable conduct, if
    not by a very great margin. In reaching the decision we do, we hardly mean to
    suggest a government agent’s need to attend to other assignments will always
    justify delay of this length. If, for example, the evidence showed the agent could
    have readily transferred his current case or his newly assigned responsibilities to
    someone else, our judgment might be different. If, too, Mr. Wulf had not
    voluntarily relinquished the computer or someone had sought its return, our
    judgment might be different. To decide this case we need only hold (and only
    hold) that when an investigator obtains property by consent and retains it without
    objection, and when his search is delayed by virtue of having to attend to other
    and higher law enforcement priorities and no evidence suggests a reassignment
    was reasonably possible, a five-month delay isn’t constitutionally unreasonable.
    See Stabile, 
    633 F.3d at 236
     (holding three-month search delay reasonable when
    officer was reassigned to another matter); Mitchell, 
    565 F.3d at 1353
     (holding a
    three-week delay unreasonable, but noting the case would be different if the
    government had shown the need to “diver[t] . . . law enforcement personnel to
    another case”).

    B
    Next Ms. Christie attacks the validity of the second warrant, this one issued
    in May 2009, to conduct a more thorough search of her computer. She argues this
    warrant violated the Fourth Amendment’s promise that “no Warrants shall issue”
    without “particularly describing the place to be searched, and the persons or
    things to be seized.” The concern originally animating this so-called
    “particularity requirement” was a wish to prevent the sort of warrants English
    kings once favored, ones that proscribed few limits on the scope of the search to
    be conducted and included no explanation why they were issued. Even today the
    particularity requirement remains a vital guard against “wide-ranging exploratory
    searches,” a promise that governmental searches will be “carefully tailored to
    [their] justifications.” Maryland v. Garrison, 
    480 U.S. 79
    , 84 (1987). Probable
    cause to believe a suspect possesses a stolen car may justify issuing a warrant
    authorizing the search of her garage but not necessarily her attic, and probable
    cause to believe a gang member is hiding weapons may merit a warrant to conduct
    a search of his home but not necessarily his grandmother’s. A warrant isn’t ever
    supposed to be a license for just “a general . . . rummaging.” United States v.
    Brooks, 
    427 F.3d 1246
    , 1251 (10th Cir. 2005).
    No doubt the particularity requirement and its underlying purposes are fully
    engaged when investigators seek to search a personal computer. Personal
    computers can and often do hold “much information touching on many different
    -11-
    areas of a person’s life.” United States v. Walser, 
    275 F.3d 981
    , 986 (10th Cir.
    2001). They can contain (or at least permit access to) our diaries, calendars, files,
    and correspondence — the very essence of the “papers and effects” the Fourth
    Amendment was designed to protect. U.S. Const. amend. IV. In today’s world, if
    any place or thing is especially vulnerable to a worrisome exploratory rummaging
    by the government, it may be our personal computers.
    This court’s efforts to apply the Fourth Amendment’s particularity
    requirement to computer searches are still relatively new. But the parties seem to
    agree that our cases already draw at least one recognizable line. On the one hand,
    we have held invalid warrants purporting to authorize computer searches where
    we could discern no limiting principle: where, for example, the warrant permitted
    a search of “‘any and all’ information, data, devices, programs, and other
    materials,” United States v. Otero, 
    563 F.3d 1127
    , 1132-33 (10th Cir. 2009)
    (alteration omitted), or “all computer and non-computer equipment and written
    materials in [a defendant’s] house,” Mink v. Knox, 
    613 F.3d 995
    , 1011 (10th Cir.
    2010). On the other hand, we have said warrants may pass the particularity test if
    they limit their scope either “to evidence of specific federal crimes or [to] specific
    types of material.” United States v. Riccardi, 
    405 F.3d 852
    , 862 (10th Cir. 2005);
    see also United States v. Campos, 
    221 F.3d 1143
    , 1147 (10th Cir. 2000); United
    States v. Burke, 
    633 F.3d 984
    , 992 (10th Cir. 2011); Brooks, 
    427 F.3d at 1252
    .
    -12-
    Having more or less agreed on the current state of our jurisprudence, the
    parties proceed to debate on which side of the line our warrant falls. Is it more
    like Otero and Mink, or more like Campos, Brooks, and Burke? The October
    2009 warrant authorized a search of Ms. Christie’s computer for
    [a]ll records and information relating to the murder, neglect, and abuse of
    [BW] from June 19, 2002 (date of birth) to May 4, 2006, (date computer
    seized), including:
    1.      All photographs of [BW].
    2.      All correspondence and/or documents relating to [BW].
    3.      All records and information, including any diaries or calendars,
    showing the day-to-day activities of Rebecca Christie and/or [BW].
    4.      All addresses and/or contact information of friends, families, or
    acquaintances who may have had regular contact with Rebecca
    Christie and/or [BW].
    According to Ms. Christie, paragraph 3 effectively permitted law
    enforcement to search any and all records and information on her computer for
    any and all purposes. And this, she says, authorized an unprincipled and
    unlimited search of the sort we held invalid in Otero and Mink.
    The government responds that all of its search efforts, including those
    authorized in paragraph 3, were restricted by the warrant’s opening language. In
    support of its interpretation, the government points to Brooks where this court
    read a similar warrant as “naturally” restricting all subsequently enumerated
    searches to the scope set forth at the warrant’s outset. See Brooks, 
    427 F.3d at 1252
    . Advocating a parallel construction here, the government says paragraph 3
    didn’t authorize it to rifle through Ms. Christie’s files looking for any sort of
    -13-
    incriminating evidence. Instead, it had to direct all of its search efforts, including
    those specified in paragraph 3, to information related “to the murder, neglect, and
    abuse” of BW. And that limiting direction, the government submits, is
    particularity enough under our case law.
    We find it hard to fault the government’s reasoning. Though the warrant
    before us is surely open to interpretation, Brooks did approve a similar one on the
    basis that its opening language limited the scope of all later enumerated searches
    to seeking evidence of particular federal crimes. At the very least, in light of
    Brooks we cannot deny that an objectively reasonable officer acting in good faith
    could have read the warrant before us in this same manner — as restricting the
    scope of any search to information “related to the murder, neglect, and abuse of”
    BW and thus analogous to the warrants we upheld in Brooks, Campos, and Burke.
    And to know just that much is to know suppression cannot follow. The Fourth
    Amendment’s exclusionary rule will “not bar the use of evidence obtained by
    police officers acting in good faith and with reasonable reliance on a facially
    valid search warrant.” United States v. Tisdale, 
    248 F.3d 964
    , 972 (10th Cir.
    2001) (citing United States v. Leon, 
    468 U.S. 897
    , 919-20 (1984)). In light of our
    past approval of a similar warrant, it seems more than a little difficult for us to
    say now that “a reasonably well trained officer would have known that the
    search” in this case “was illegal despite the magistrate’s authorization.” 
    Id.
    -14-
    Ms. Christie rejoins that if our current case law endorses the warrant in this
    case then our case law needs to be reexamined. In an age where computers permit
    access to most every “paper and effect” a person owns, she fears that merely
    restricting the government to a search topic or objective does little to prevent it
    from examining along the way virtually every bit and byte of our lives. Risking
    with it the possibility the government will claim to find “in plain view” evidence
    of crimes totally unrelated to the reasons spurring their search in the first place.
    The text of the Fourth Amendment says the government must identify with
    particularity “the place to be searched” and requiring it to describe that place
    tersely as “a computer” is to allow the government to traipse willy-nilly through
    an entire virtual world. To prevent that, Ms. Christie suggests a warrant must go
    further: it must specify limitations not just what the government may search for
    but how the government should go about its search.
    In reply, the government argues that it’s often difficult to know what search
    protocols might be reasonably required at the time of a warrant application,
    before the computer has been examined. Computer files can be misnamed by
    accident, disguised by intention, or hidden altogether, leaving investigators at a
    loss to know ex ante what sort of search will prove sufficient to ferret out the
    evidence they legitimately seek. See Burgess, 
    576 F.3d at 1093
    ; Brooks, 
    427 F.3d at 1252
    . Neither has the particularity requirement, the government points out,
    ever been understood to demand of a warrant “technical precision,” United States
    -15-
    v. Simpson, 
    152 F.3d 1241
    , 1248 (10th Cir. 1998), or “elaborate detail,” United
    States v. Triplett, 
    684 F.3d 500
    , 504 (5th Cir. 2012), but only “practical”
    limitations, Simpson, 
    152 F.3d at 1248
    , affording “reasonabl[e] specific[ity],”
    United States v. Adjani, 
    452 F.3d 1140
    , 1149 (9th Cir. 2006). Though this court’s
    efforts to apply the Fourth Amendment’s particularity requirement to computer
    searches are still relatively new and our existing treatment is far from
    comprehensive, it also seems difficult to square Ms. Christie’s demand for a how
    with our existing cases (Brooks, Burke, Campos, and Riccardi), all of which
    suggest a what may be particular enough. Indeed, we’ve gone so far as to suggest
    that it is “unrealistic to expect a warrant to prospectively restrict the scope of a
    search by directory, filename or extension or to attempt to structure search
    methods — that process must remain dynamic.” Burgess, 
    576 F.3d at 1093
    .
    This isn’t to say the Fourth Amendment has nothing to say on how a
    computer search should proceed. Even putting aside for the moment the question
    what limitations the Fourth Amendment’s particularity requirement should or
    should not impose on the government ex ante, the Amendment’s protection
    against “unreasonable” searches surely allows courts to assess the propriety of the
    government’s search methods (the how) ex post in light of the specific
    circumstances of each case. See, e.g., United States v. Ramirez, 
    523 U.S. 65
    , 71
    (1998) (“The general touchstone of reasonableness . . . governs the method of
    execution of the warrant.”); United States v. Angelos, 
    433 F.3d 738
    , 746 (10th
    -16-
    Cir. 2006). So even if courts do not specify particular search protocols up front
    in the warrant application process, they retain the flexibility to assess the
    reasonableness of the search protocols the government actually employed in its
    search after the fact, when the case comes to court, and in light of the totality of
    the circumstances. Unlike an ex ante warrant application process in which the
    government usually appears alone before generalist judges who are not steeped in
    the art of computer forensics, this ex post review comes with the benefit, too, of
    the adversarial process where evidence and experts from both sides can be
    entertained and examined. See Burgess, 
    576 F.3d at 1094
    ; United States v. Carey,
    
    172 F.3d 1268
    , 1275-76 (10th Cir. 1999); Orin S. Kerr, Searches and Seizures in
    a Digital World, 
    119 Harv. L. Rev. 531
    , 574-75 (2005).
    Whenever courts should review search protocols and whatever the scope of
    our authority to do so may be, one thing is certain. To undertake any meaningful
    assessment of the government’s search techniques in this case (the how), we
    would need to understand what protocols the government used, what alternatives
    might have reasonably existed, and why the latter rather than the former might
    have been more appropriate. Unfortunately, however, that we do not have in this
    case. Though Ms. Christie bore the burden of proof in her suppression
    proceeding, she offered little evidence or argument suggesting how protocols the
    government followed in this case were unreasonable or insufficiently particular,
    especially when compared with possible alternatives. Without more help along
    -17-
    these lines, we simply cannot assess rationally her challenge to the government’s
    search procedures in this case and must leave the development of the law in this
    arena to future cases.
    C
    In her final Fourth Amendment attack, Ms. Christie returns to the theme of
    faulting the government for its delay in seeking a warrant. This time the focus of
    her complaint is the second, May 2009 warrant. But the government’s delay in
    seeking this warrant poses much less of a concern than its delay in seeking the
    first warrant. After the government executed its first search warrant and found
    incriminating evidence, it was presumptively entitled to retain the computer
    through trial. “[T]he general rule is that” lawfully seized property bearing
    evidence relevant to trial “should be returned to its rightful owner once the
    criminal proceedings have terminated,” not before. United States v. Rodriguez-
    Aguirre, 
    264 F.3d 1195
    , 1212 (10th Cir. 2001); see also United States v.
    Thomson, 
    354 F.3d 1197
    , 1201 (10th Cir. 2003). Ms. Christie offers no reason to
    think her case an exception to this general rule. And without a right to the
    computer’s return until after trial, it’s hard to see how she had any interest that
    could be impaired by a second (and itself otherwise lawful) search during the
    period of the government’s lawful possession, let alone by the timing of that
    -18-
    second search. Neither does Ms. Christie identify any authority or reason
    suggesting otherwise. 2
    III
    When it comes to the conduct of the trial itself, Ms. Christie objects to the
    district court’s decision to exclude Mr. Wulf from the courtroom during the brief
    testimony of his ten-year-old daughter. Mr. Wulf’s exclusion, Ms. Christie
    insists, violated her Sixth Amendment right to a public trial. See U.S. Const.
    amend. VI (“in all criminal prosecutions, the accused shall enjoy the right to . . . a
    public trial”). According to Ms. Christie, before closing the courtroom in this
    way the district court had — but failed — to satisfy the detailed four-part test
    announced in Waller v. Georgia: “[1] the party seeking to close the hearing must
    advance an overriding interest that is likely to be prejudiced, [2] the closure must
    be no broader than necessary to protect that interest, [3] the trial court must
    2
    Ms. Christie presses two other suppression arguments, but neither merits
    extended discussion. First, in contesting the second warrant, she suggests the
    government lacked probable cause to think the computer contained evidence
    related to the charges against her. But by the time of the second warrant the
    government had amassed a great deal of evidence suggesting not only that BW
    died as a result of Ms. Christie’s neglectful treatment, but also that Ms. Christie’s
    computer would yield further valuable evidence. Second, Ms. Christie contends
    the temporal scope of the second warrant was overbroad, authorizing as it did a
    search for materials dated from BW’s birth to after her death. But evidence
    during this entire period — again, so long as it “relate[d] to the murder, neglect,
    and abuse of” BW — was relevant to the case. The government, for example, had
    to prepare to rebut the defense’s suggestion that BW’s death was caused by her
    preexisting medical problems rather than Ms. Christie’s neglect, and the
    government could do so only by showing that BW was (relatively) healthy before
    Ms. Christie assumed sole responsibility for her care.
    -19-
    consider reasonable alternatives to closing the proceeding, and [4] it must make
    findings adequate to support the closure.” 
    467 U.S. 39
    , 48 (1984).
    Waller’s stringent test, however, applies only to “the total closure of a
    trial.” United States v. Galloway, 
    937 F.2d 542
    , 546 (10th Cir. 1991). Here the
    courtroom was closed only to a single person (not the entire public), and only
    while a single witness (Mr. Wulf’s daughter) testified. Of course it’s still no
    small thing to exclude anyone from any portion of a trial. But where the potential
    invasion of Sixth Amendment interests is so much less likely, the test a district
    court must satisfy is correspondingly less onerous. We have explained that to
    support a partial closure of a trial, the district court need only identify a
    “‘substantial’ interest, rather than a ‘compelling’ one” and document it with
    “sufficient findings to allow the reviewing court” to assess the decision. 
    Id.
    Our cases have yet to inscribe a definitive and exhaustive list of what
    qualifies as a “substantial interest” and today we don’t claim the insight necessary
    to craft a definition sufficient to cover all future cases. But in light of existing
    precedent we can say this much: “safeguarding the physical and psychological
    well-being of a minor” qualifies not just a substantial interest but a compelling
    one. See Globe Newspaper Co. v. Superior Court for Norfolk Cnty., 
    457 U.S. 596
    , 607 (1982). Factors that may play into this calculus include the witness’s
    age and relationship to the person excluded from the courtroom, the nature of the
    -20-
    alleged offense, and the harm the witness may reasonably expect to face without
    the court’s protection. See Galloway, 
    937 F.2d at 546
    .
    In our case, there is no suggestion that Mr. Wulf’s presence would have
    posed a physical danger to his daughter: there was no need to close the
    courtroom to protect the girl in that sense. But there were concerns about
    protecting the girl’s psychological well-being. The district court observed that
    Mr. Wulf’s daughter was only ten years old. It heard her testify that “she would
    be afraid to talk” if her father was present, that she feared having to explain he
    too was sometimes negligent in caring for BW. And the court found that forcing
    the girl to testify in her father’s presence would place at risk her psychological
    well-being by undermining her long-term relationship with her father. No
    evidence before us suggests the district court’s assessment was wrong in any
    respect.
    Of course we must still consider this interest in “balance” against those the
    Sixth Amendment seeks to protect. A public trial is a potent disinfectant, a
    republican assurance against the corruption that breeds in collusive environments.
    Though the benefits public scrutiny brings to a trial may be diffuse and
    “frequently intangible,” Waller, 
    467 U.S. at
    49 n.9, the history of secret tribunals
    teaches that the right to a public trial serves many important interests, including
    at least these: it does much to ensure the trial is conducted fairly, to remind the
    lawyers and judge of their responsibilities to the accused and the importance of
    -21-
    their functions, to encourage possible witnesses to come forward, and to
    discourage perjury. See Nieto v. Sullivan, 
    879 F.2d 743
    , 753 (10th Cir. 1989)
    (citing Waller, 
    467 U.S. at 46
    ); In re Oliver, 
    333 U.S. 257
    , 266-70 (1948)
    (discussing the evolution of the public trial guarantee); Akhil Reed Amar, Sixth
    Amendment First Principles, 
    84 Geo. L.J. 641
    , 677-81 (1996); Max Radin, The
    Right to a Public Trial, 6 Temp. L.Q. 381 (1932).
    But in this case, none of these underlying Sixth Amendment interests was
    meaningfully impaired. The girl’s testimony lasted only minutes in a trial that
    lasted days. Save Mr. Wulf, all members of the public were free to attend even
    the girl’s testimony. Ms. Christie doesn’t claim the prosecutors or judge took
    their responsibilities any less seriously or that a witness was less likely to come
    forward. Neither does Ms. Christie argue this limited closure prompted the girl
    (let alone any other witness) to testify falsely, and she does not suggest the
    closure deprived her of an opportunity for effective cross examination.
    We do not mean to suggest in any way that the temporary exclusion of one
    individual from a trial will always be constitutionally acceptable. The Sixth
    Amendment is more demanding than that. But in the circumstances here we
    simply discern no meaningful Sixth Amendment interest to weigh against the need
    to protect a child’s psychological well-being, an interest that qualifies under the
    -22-
    precedent of the Supreme Court as substantial enough to justify even the
    temporary closure of a courtroom let alone the exclusion of a single witness. 3
    IV
    That takes us to the government’s cross-appeal. At the end of Ms.
    Christie’s trial, the jury convicted her of one federal charge (second-degree
    murder) and three crimes assimilated from New Mexico state law (intentional
    child abuse resulting in death, negligent child abuse resulting in death, and
    3
    Ms. Christie raises two other complaints about her trial and sentencing
    but both are significantly less compelling.
    First, she argues that the trial record contains insufficient evidence to
    sustain her second-degree murder charge. Everyone agrees that to prevail on that
    charge the government had to show “conduct which is reckless and wanton, and a
    gross deviation from a reasonable standard of care, of such a nature that a jury is
    warranted in inferring that defendant was aware of a serious risk of death or
    serious bodily harm.” United States v. Wood, 
    207 F.3d 1222
    , 1228 (10th Cir.
    2000). Ms. Christie says the government failed to prove she possessed the
    requisite state of mind in light of (among other things) her testimony professing
    ignorance of BW’s condition. But on a sufficiency challenge, an appellant must
    prove that no “rational trier of fact” could think the government met its burden.
    United States v. Hutchinson, 
    573 F.3d 1011
    , 1033 (10th Cir. 2009). And on the
    facts as we’ve outlined them, we have no doubt a rational juror could have
    disbelieved Ms. Christie’s account and concluded that she saw and disregarded
    BW’s glaring and dire symptoms.
    Second and for similar reasons, we reject Ms. Christie’s challenge to the
    district court’s application of a sentencing enhancement (U.S.S.G. § 3C1.1) for
    testifying falsely. Ms. Christie insists the district court’s finding — that she lied
    about being unaware of the severity of BW’s condition — was wrong. But to
    unseat the district court’s factual finding, she must show the court clearly erred.
    And just as we cannot say any rational juror had to believe her story over the
    government’s competing evidence, neither can we say the district court had to do
    so.
    -23-
    negligent child abuse not resulting in death). After receiving the verdict, the
    district court proceeded to dismiss the two assimilated homicide charges, leaving
    Ms. Christie responsible for second-degree murder and negligent child abuse not
    resulting in death. In explaining its dismissal of the assimilated homicide
    charges, the court pointed to the fact New Mexico does not permit more than one
    homicide conviction per death and, in this case, Ms. Christie already stood
    convicted for second-degree murder.
    This logic, the government now argues, was in error and the assimilated
    homicide charges should be reinstated. Ms. Christie claims error too but in the
    opposite direction. She argues the district court was right in dismissing the
    assimilated homicide charges at the end of trial but should never have permitted
    them to go the jury in the first place.
    For our part, we affirm the district court’s chosen middle path between
    these extremes. It’s clear to us that the district court had to dismiss the
    assimilated charges as a matter of law after trial for two separate but related
    reasons: the first grounded in the statutory commands of the Assimilative Crimes
    Act (ACA), 
    18 U.S.C. § 13
    , and the second based on our received double
    jeopardy doctrine. Whether the district court might have been obliged to dismiss
    the charges before trial as Ms. Christie argues is a question we don’t have to
    tangle with. We don’t because even assuming some conceivable error arose from
    -24-
    the district court’s decision to dismiss the assimilate homicide counts later rather
    than sooner, any such error was surely harmless.
    A
    Take the ACA first. With few exceptions, federal courts have abjured the
    power to fashion a federal common law of crime, holding that the Constitution
    generally assigns the job of specifying federal crimes and punishments to the
    Legislative Branch. See, e.g., Liparota v. United States, 
    471 U.S. 419
    , 424
    (1985); United States v. Hudson & Goodwin, 11 U.S. (7 Cranch) 32, 34 (1812).
    In the early days of the republic when federal criminal statutes were few
    (different days than our own), this meant federal enclaves — places like the
    military base in this case where the federal government alone enjoys sovereign
    power — were pretty literally lawless.
    Responding to this problem in the 1820s, Daniel Webster introduced the
    ACA. Instead of trying to write an exhaustive criminal code for federal enclaves,
    Webster sought more expeditiously and cleverly to borrow from preexisting state
    law. A testament to its efficacy and economy of design, the ACA remains today
    little changed from its original form, providing that anyone “guilty of any act or
    omission which, although not made punishable by any enactment of Congress,
    would be punishable if committed . . . within the jurisdiction of the State . . . in
    which [the federal enclave] is situated, . . . shall be guilty of a like offense and
    -25-
    subject to a like punishment.” 
    18 U.S.C. § 13
    (a); see also Lewis v. United States,
    
    523 U.S. 155
    , 160-61 (1998); 
    id. at 179
     (Scalia, J., concurring in the judgment).
    Sometimes questions about the propriety of an assimilated charge will arise
    and can be resolved early in a criminal case. If, for example, it’s clear that a
    federal statute applies to the defendant’s conduct and that the assimilation of a
    state law applying to that same conduct would “interfere with the achievement of
    a federal policy” or “effectively rewrite an offense definition that Congress
    carefully considered,” or enter a field Congress has expressed an “intent to
    occupy,” then the need for dismissing an assimilated crime may be evident even
    before trial. See 
    id. at 164
    .
    Sometimes, though, it will be difficult to resolve ACA questions until after
    trial. The statute after all, addresses not only which charges may be brought but
    also which punishments may be meted out, instructing that for crimes properly
    assimilated into federal proceedings courts may impose only “like punishment[s]”
    to those state courts can impose. See 
    18 U.S.C. § 13
    (a). In this way the statute
    plays an important role not just at trial but at sentencing, requiring federal courts
    “to provide a method of punishing a crime committed on government reservations
    in the way and to the extent that it would have been punishable if committed
    within the surrounding jurisdiction.” United States v. Sain, 
    795 F.2d 888
    , 890
    (10th Cir. 1986) (emphasis added). And, of course, not infrequently sentencing
    issues are difficult to anticipate in advance of trial.
    -26-
    In this case we are certain at least this latter sentencing-related feature of
    the ACA required the district court to dismiss the assimilated state law claims
    after trial. New Mexico, it turns out, prohibits the entry of convictions for child
    abuse-resulting-in-death alongside a conviction for any other form of homicide.
    See State v. Santillanes, 
    27 P.3d 456
    , 468 & n.3 (N.M. 2001); State v. Mann, 
    11 P.3d 564
    , 570 (N.M. 2000). It is, the parties before us both acknowledge, the
    state’s avowed penal policy that one death should result in only one homicide
    conviction: if the jury convicts on multiple homicide charges, all but the most
    serious must be vacated after trial. Here, Ms. Christie stood convicted of second-
    degree murder as well as the two child-abuse-resulting-in-death charges. Had she
    been tried in state court, there’s no question a state court would have dismissed
    the latter two charges after trial. The only way the district court could obey the
    ACA’s textual “like punishment” directive was to do the same. This circuit and
    others have unanimously interpreted the ACA’s “like punishment” mandate to
    require federal sentencing courts to abide any maximum and minimum prison
    terms proscribed by state law for an assimilated crime. See United States v.
    Garcia, 
    893 F.2d 250
    , 254 (10th Cir. 1989); see also United States v. Martinez,
    
    274 F.3d 897
    , 906 & n.12 (5th Cir. 2001) (collecting cases). When the maximum
    punishment a state court can impose for a conviction is “nothing,” it follows that
    the same must hold true in a federal ACA proceeding.
    -27-
    Neither can there be any question that a conviction on a defendant’s record
    amounts to a form of “punishment” subject to the ACA’s “like punishment”
    command. Even when it results only in a concurrent prison sentence or no prison
    sentence at all, a conviction surely bears “adverse collateral consequences that
    may not be ignored”: its presence on a defendant’s record may delay her
    “eligibility for parole or result in an increased sentence under a recidivist statute
    for a future offense,” it may be “used to impeach the defendant’s credibility” and
    it “certainly carries the societal stigma accompanying any criminal conviction.”
    Ball v. United States, 
    470 U.S. 856
    , 865 (1985). All of this is plainly
    “punishment” indeed. 
    Id.
    To be sure, the ACA requires like punishment, not precisely the same
    punishment. It is not necessary, for example, for federal courts to “duplicate
    every last nuance of the sentence that would be imposed in state court.” Garcia,
    
    893 F.2d at 254
    . And federal courts must depart from state guidance when
    Congress has expressed a specific and contrary penal policy. 
    Id.
     So, for
    example, we do not require district courts to follow state parole policies given
    Congress’s express abolition of parole in the federal system. See United States v.
    Pinto, 
    755 F.2d 150
    , 154 (10th Cir. 1985). Neither may federal courts ignore
    congressionally mandated sentencing guidelines in favor of state sentencing
    guidelines. See Garcia, 
    893 F.2d at 254
    . And federal courts cannot impose the
    death penalty relying on state law when doing so would upset Congress’s
    -28-
    judgment about when capital punishment is and is not warranted. See Lewis, 
    523 U.S. at 170
    . These examples of mandatory departures from the “like punishment”
    principle are all particular illustrations of the broader principle that when it comes
    to resolving competing congressional directions the specific (here, regarding
    parole, sentencing policy, and the death penalty) controls over the general (here,
    ACA’s generic “like punishment” principle). See RadLAX Gateway Hotel, LLC v.
    Amalgamated Bank, 
    132 S. Ct. 2065
    , 2071 (2012); Elwell v. Oklahoma ex rel. Bd.
    of Regents, 
    693 F.3d 1303
    , 1310 (10th Cir. 2012).
    Whether or not a conviction stands or falls, however, cannot be sensibly
    described as a nuance and we see no conflicting and more specific congressional
    direction in play in our case. Congress has not mandated, or even suggested, that
    a federal court must enter separate convictions for murder and the assimilated
    crimes. Instead, the only congressional direction we have is the ACA’s general
    command to impose only “like punishment” and, in the absence of any more
    specific direction, that command must be respected.
    B
    Apart from the ACA but not wholly unrelated to it, there remains the
    question of double jeopardy. The Supreme Court has said that the Double
    Jeopardy Clause of the Fifth Amendment protects not only against successive
    trials on the same charges but also against “multiple punishments for the same
    offense.” Whalen v. United States, 
    445 U.S. 684
    , 688 (1980) (quotation marks
    -29-
    omitted). Sometimes called a guarantee against “multiplicitous punishments,”
    this feature of due process doctrine “prevent[s] the sentencing court from
    prescribing greater punishment than the legislature intended.” Missouri v.
    Hunter, 
    459 U.S. 359
    , 366 (1983). Put plainly, federal courts cannot impose
    cumulative punishments unless Congress has authorized them. It may be a nice
    question whether this rather simple and intuitive rule flows more naturally from
    the double jeopardy clause or from the Constitution’s separation of powers, see
    Whalen, 
    445 U.S. at 689
    , but whatever its source, the result in this case is the
    same: the assimilated charges against Ms. Christie must go.
    In arguing as much, however, Ms. Christie makes a mistake. Because the
    New Mexico legislature precludes cumulative punishment for homicide, she
    reasons that the federal district court had no choice but to dismiss the state
    homicide charges in light of her federal second-degree murder conviction. But
    this line of thinking misconceives the assimilated homicide charges as state law
    charges and looks directly to the intent of the New Mexico legislature. This is a
    misconception because an assimilated charge is a federal charge. Offenses
    properly assimilated into federal law are no less part of federal law than, say,
    Congress’s statutorily defined second-degree murder charge. See Sain, 
    795 F.2d at 891
    . Indeed, if assimilated charges were truly state charges, a federal court
    would lack the authority to enforce them in the first place. Knowing this much,
    -30-
    we see it is Congress’s directions about cumulative punishment — not New
    Mexico’s — that must control our double jeopardy analysis.
    How can we discern whether Congress meant to authorize cumulative
    punishment in this case? Especially when the federal murder statute gives us no
    express direction on the issue? The Supreme Court has instructed us to apply the
    “same elements test” as a proxy for congressional intent in the usual case. See
    Blockburger v. United States, 
    284 U.S. 299
    , 304 (1932); see also Hunter, 
    459 U.S. at 367-68
    . This test requires us to “inquire[] whether each offense” at issue
    “contains an element not contained in the other.” United States v. Dixon, 
    509 U.S. 688
    , 696 (1993). If the answer is yes, we are told to say Congress
    authorized punishments for both offenses; if the answer is no, we are instructed to
    say Congress authorized punishment for only one offense. 
    Id.
     But whatever
    virtue the Blockburger “same elements test” may have as a proxy for
    congressional intent, it surely depends on an assumption that Congress wrote all
    the statutes in question, choosing whether to frame one offense with elements that
    do or do not overlap with elements of another. Our case, however, poses a
    quandary, given that Congress did not define the assimilated homicide offenses
    and could not have crafted their elements in light of the text of its own murder
    statute. Given this complication, what to do?
    The answer lies in the statute Congress did write: the ACA. When a
    federal statute contains a plainly expressed direction on the question of multiple
    -31-
    punishments, it — rather than Blockburger’s proxy — controls. See Garrett v.
    United States, 
    471 U.S. 773
    , 779 (1985) (“[T]he Blockburger presumption must of
    course yield to a plainly expressed contrary view on the part of Congress.”).
    After all, why employ a proxy for congressional intent when we have direct
    evidence of Congress’s wishes? See, e.g., United States v. Lovett, 
    964 F.2d 1029
    ,
    1042 (10th Cir. 1992); United States v. Hampton, 
    786 F.2d 977
    , 979-80 (10th Cir.
    1986). And in this case, the ACA tells us specifically and directly how much
    punishment Congress wants us to impose.
    All this takes us now full circle to our earlier statutory interpretation
    discussion. The ACA authorizes federal courts to impose “like punishment” and
    no more. This textual command expresses Congress’s judgment that federal
    punishment for assimilated crimes should be no more severe than what a state
    court can impose. And as we’ve already seen, “like punishment” in this case
    means no punishment at all because in similar circumstances New Mexico courts
    would have to dismiss both of the child-abuse-resulting-in-death convictions
    given the presence of another homicide conviction. So, as a matter of federal law
    and congressional direction — whether one conceives of the issue merely as one
    of statutory interpretation or more grandly as one of double jeopardy (or
    separation of power for that matter) — Ms. Christie cannot stand convicted of
    both second-degree murder and the dismissed offenses.
    -32-
    C
    One final issue we’ve alluded to remains to be confronted. Ms. Christie
    applauds the district court’s dismissal of the state homicide charges after the jury
    returned its verdict. But in her view the district court erred by failing to dismiss
    the charges before trial. The “like punishment” (ACA) and “multiplicitous
    punishment” (double jeopardy) problems we’ve discussed arose only at the end of
    the case when it came clear the jury found Ms. Christie guilty of second-degree
    murder under federal law and guilty as well of the two assimilated state homicide
    offenses. At that point, the district court had to act, it had to dismiss the
    assimilated homicide offenses, to honor the ACA’s “like punishment” command.
    But, as we’ve seen, the ACA speaks not only to the punishments federal courts
    may impose but also to the charges government may bring. And Ms. Christie
    contends an independent and equally apparent ACA charging problem arose
    before trial, a problem that the district court should have seen and failed to
    confront. She says the district court ignored the ACA’s textual command to
    assimilate “like” state offenses only when a defendant “is guilty of any act or
    omission . . . not made punishable by any enactment of Congress.” In her view,
    the federal murder and manslaughter statutes so completely occupy the field of
    homicide that they obviously leave no room for assimilating state law child abuse
    crimes. Accordingly, the district court should have dismissed those claims before
    -33-
    the case was placed before the jury. For its part, the concurrence agrees with Ms.
    Christie at least that far.
    We confess we are less sure. Lewis certainly teaches that the federal
    murder statute, 
    18 U.S.C. § 1111
    , occupies the field of killing with “malice
    aforethought” and, in doing so, precludes the assimilation of state charges
    covering that same ground. But it’s far from clear to us whether the two state
    charges at issue here trench on that territory. “Malice aforethought” is a common
    law term that denotes an intent to kill or to cause serious injury, or reckless
    disregard for human life. Wood, 
    207 F.3d at 1228
    . That mental state clearly does
    not extend to mere negligence, yet one of the state homicide charges at issue here
    aims specifically at negligent child abuse resulting in death. Even the other state
    child abuse offense at issue requires only an intent to abuse, see 
    N.M. Stat. Ann. § 30-6-1
    (D), and it’s not entirely clear whether that intent, as the state defines it,
    must amount to a reckless disregard for human life or an intent to kill or cause
    serious injury.
    Alternatively, we might examine whether the state offenses conflict with
    the federal definition of felony murder. But that course turns out to raise thorny
    questions of its own. For example, we have suggested that a killing in the course
    of committing any felony satisfies the malice requirement for second-degree
    murder. United States v. Pearson, 
    159 F.3d 480
    , 486 (10th Cir. 1998). The
    assimilated charges are, of course, in precisely that form: a killing in the course
    -34-
    of the assimilated felony of child abuse. But the common-law definition of felony
    murder endorsed in Pearson might be read more narrowly, as requiring the
    predicate felony to be one that was recognized at common law or one whose
    required mens rea would, if transferred to the homicide, meet the “malice
    aforethought” standard. See Wayne R. LaFave, Substantive Criminal Law
    § 14.5(b); cf. United States v. Chischilly, 
    30 F.3d 1144
    , 1159-60 (9th Cir. 1994)
    (finding no scope for federal felony murder outside the enumerated list of crimes
    amounting to first-degree murder). And it is entirely unclear whether the state
    homicide crimes could meet this narrower standard, or whether we’ve ever
    actually upheld a felony murder conviction that hasn’t met this narrower standard.
    Neither are we sure the assimilation of the two state offenses at issue
    before us necessarily offend the federal manslaughter statute. The two offenses
    do not purport to address situations in which a homicide occurs in the course of
    “a sudden quarrel or heat of passion,” as the federal voluntary manslaughter
    statute does. 
    18 U.S.C. § 1112
    (a). The two offenses, as well, are clearly unlawful
    and felonious acts under New Mexico law, and this may mean that one who
    commits them is necessarily not guilty of federal involuntary manslaughter. The
    federal involuntary manslaughter statute, after all, covers only killings “[i]n the
    commission of an unlawful act not amounting to a felony, or in the commission in
    an unlawful manner, or without due caution and circumspection, of a lawful act
    which might produce death.” 
    Id.
     (emphasis added). Additionally, the ACA
    -35-
    expressly contemplates the assimilation of at least some state homicide statutes
    that seem to overlap with federal manslaughter, see 
    18 U.S.C. § 13
    (b)(2)(A)(i)
    (increasing the punishment for assimilated DUI offenses resulting in death), so
    it’s not even clear Congress has any intent to occupy the field of unintentional
    homicides.
    Some day this court may have to resolve these tricky questions. We have
    no doubt that when it does, the court and litigants alike will be aided by the
    concurrence’s thoughtful discussion. But for now we don’t need to go so far. We
    don’t because even assuming (without deciding) that the district court committed
    an error by failing to dismiss the state homicide charges before trial as Ms.
    Christie and the concurrence contend, any such error was surely harmless. And
    on this more modest and entirely dispositive point, we and the concurrence find
    ourselves in full agreement.
    To be sure, Ms. Christie says she was prejudiced in the eyes of the jury.
    She acknowledges, of course, that the two state homicide charges were eventually
    dismissed after trial. But she says her defense was compromised by their
    presence until the end of trial. And at least theoretically she has a point. We do
    not doubt, for example, that the government could unduly prejudice a defendant in
    the eyes of the jury by presenting a proliferation of charges at trial that clearly
    have no lawful place there. It is not impossible to fathom a situation in which the
    sheer quantity of legally unauthorized charges might induce a jury to think the
    -36-
    defendant must be guilty of something. See United States v. Johnson, 
    130 F.3d 1420
    , 1426 (10th Cir. 1997); United States v. Ketchum, 
    320 F.2d 3
    , 8 (2d Cir.
    1963) (Friendly, J.); Pointer v. United States, 
    151 U.S. 396
    , 403 (1894).
    That, however, is not our case. The district court took care to instruct the
    jury to consider each count independently without regard to others. The number
    and character of the contested charges were relatively modest: just two
    challenged charges were placed before the jury, and both were lesser species of
    homicide than the federal murder charge everyone agrees was properly at issue.
    The evidence against Ms. Christie on each count of conviction was, as well,
    frankly overwhelming. Given all of these reassuring facts and the absence of any
    contrary indication that the jury was swayed by the number of charges rather than
    the evidence presented, we believe Rule 52(a) of the Federal Rules of Criminal
    Procedure permits us to “disregard[]” any conceivable error here on the ground
    that it did not affect Ms. Christie’s “substantial rights.” We simply do not see
    how the presence of these two charges during this trial with this evidence and
    these jury instructions could have made any difference. In concluding as much,
    we reach the same destination and by much the same reasoning we did in
    Johnson, where we held that any conceivable error arising from the district
    court’s failure to force the government to choose between charges before trial was
    harmless given the “overwhelming” evidence of guilt presented on the charges
    that properly remained by the time of final judgment. 
    130 F.3d at 1426
    .
    -37-
    So it is we decline to reverse the district court on this score, just as we find
    no other reversible error anywhere else in its careful treatment of this sad case.
    The judgment is affirmed.
    -38-
    Nos. 11-2106 & 11-2221, United States v. Christie
    BRISCOE, Chief Judge, concurring
    I join all but Part IV of the majority’s well reasoned opinion. Part IV of
    majority opinion addresses two issues: 1) Ms. Christie’s assertion that the state
    law homicide charges should not have gone to the jury and that she was
    prejudiced by the resulting multiplicitous counts and erroneous jury instructions,
    see Aplt. Br. at 19-27; and 2) the government’s cross-appeal in which it asserts
    that the district court erred in vacating the two state law homicide convictions,
    see Aplee Br. at 66-71. I would answer these questions by following the Supreme
    Court’s approach in Lewis v. United States, 
    523 U.S. 155
     (1998), to conclude that
    because Congress enacted 
    18 U.S.C. §§ 1111
    (a) and 1112(a)—which criminalize
    second-degree murder and involuntary manslaughter, respectively—there was no
    need to resort to the ACA as there was no gap in federal law to fill. Any
    differences with the majority, however, are only in reasoning and not result. I
    agree in the final analysis that any error in sending the state law homicide charges
    to the jury was harmless and that the district court did not err in vacating the state
    law convictions.
    I
    We review de novo whether a state law crime was properly assimilated
    under the ACA. United States v. Rocha, 
    598 F.3d 1144
    , 1147 (9th Cir. 2010). In
    Lewis, the Supreme Court established a two-step approach for determining
    whether the ACA permits the assimilation of a particular state law:
    [T]he ACA’s language and its gap-filling purpose taken
    together indicate that a court must first ask the question that
    the ACA’s language requires: Is the defendant’s “act or
    omission . . . made punishable by any enactment of Congress.”
    
    18 U.S.C. § 13
    (a) (emphasis added). If the answer to this
    question is “no,” that will normally end the matter. The ACA
    presumably would assimilate the statute. If the answer to the
    questions is “yes,” however, the court must ask the further
    question whether the federal statutes that apply to the “act or
    omission” preclude application of the state law in question,
    say, because its application would interfere with the
    achievement of a federal policy, because the state law would
    effectively rewrite an offense definition that Congress
    carefully considered, or because federal statutes reveal an
    intent to occupy so much of a field as would exclude use of the
    particular state statute at issue.
    523 U.S. at 164 (citations omitted). The parties agree that the defendant’s act or
    omission is made punishable by an act of Congress, so we need only evaluate
    whether the applicable federal statutes in this case, 
    18 U.S.C. § 1111
    (a) (second-
    degree murder) and 
    18 U.S.C. § 1112
    (a) (involuntary manslaughter) preclude
    application of 
    N.M. Stat. Ann. § 30-6-1
     (intentional or negligent child abuse
    resulting in death).
    “The primary question . . . is one of legislative intent: Does applicable
    federal law indicate an intent to punish conduct such as the defendant’s to the
    exclusion of the particular state statute at issue?” Id. at 166. In addressing this
    question, the Supreme Court noted in Lewis that, “ordinarily, there will be no gap
    -2-
    for the Act to fill where a set of federal enactments taken together make criminal
    a single form of wrongful behavior while distinguishing (say, in terms of
    seriousness) among what amount to different ways of committing the same basic
    crime.” Id. at 165. The Lewis court then applied this standard to determine if the
    ACA assimilated Louisiana’s first-degree murder statute. For several reasons, the
    Court concluded that the federal murder statutes precluded application of a first-
    degree murder statute like Louisiana’s:
    The most obvious such feature is the detailed manner in
    which the federal murder statute is drafted. It purports to
    make criminal a particular form of wrongful behavior, namely,
    “murder,” which it defines as “the unlawful killing of a human
    being with malice aforethought.” It covers all variants of
    murder. It divides murderous behavior into two parts: a
    specifically defined list of “first-degree” murders and all
    “other” murders, which it labels “second-degree.” This fact,
    the way in which “first-degree” and “second-degree”
    provisions are linguistically interwoven; the fact that the
    “first-degree” list is detailed; and the fact that the list sets
    forth several circumstances at the same level of generality as
    does Louisiana’s statute, taken together, indicate that Congress
    intended its statute to cover a particular field—namely,
    “unlawful killing of a human being with malice
    aforethought”—as an integrated whole. The complete
    coverage of the federal statute over all types of federal enclave
    murder is reinforced by the extreme breadth of the possible
    sentences, ranging all the way from any term of years, to
    death. There is no gap for Louisiana’s statute to fill.
    Id. at 169.
    The Supreme Court also considered Congress’s careful attention to the line
    between first- and second-degree murder and as to which crimes are punishable
    by death. Id. at 169-70. In addition, the Supreme Court found it notable that
    -3-
    Congress had referred to murder “as an example of a crime covered by, not as an
    example of a gap in, federal law.” Id. at 170. Finally, the Supreme Court
    rejected the government’s argument that the specific form of first-degree murder
    it sought to assimilate, which involved the killing of a child under twelve years of
    age, filled a child-related gap in the federal murder law. The Supreme Court said
    that “the consideration to which the Government points is not strong enough to
    open a child-related ‘gap’ in the comprehensive effort to define murder on federal
    enclaves.” Id. at 172. 1
    Applying this reasoning to the case at hand, I would conclude that the
    federal murder and involuntary manslaughter statutes preclude the assimilation of
    the state child-abuse-resulting-in-death statute in this case. As the Court
    explained in Lewis, the nature of the federal murder laws shows that Congress
    intended its first- and-second degree murder statute to cover the unlawful killing
    of a human being with malice aforethought. We should extend that reasoning to
    cover involuntary manslaughter, as well. The involuntary manslaughter charge
    picks up where the murder charges leave off, and should be considered as part of
    Congress’s effort to cover, as a whole, the killing of another person.
    1
    The federal murder statute has been amended since Lewis was decided.
    Federal law now classifies as first-degree murder “[e]very murder . . . committed
    in the perpetration of, or attempt to perpetrate . . . child abuse.” 
    18 U.S.C. § 1111
    (a). Child abuse is defined as “intentionally or knowingly causing death or
    serious bodily injury to a child.” § 1111(c)(3).
    -4-
    Moreover, permitting assimilation would seemingly run afoul of the
    Supreme Court’s concerns about “leav[ing] residents of federal enclaves
    randomly subject to three sets of criminal laws (special federal territorial criminal
    law, general federal criminal law, and state criminal law) where their state
    counterparts would be subject only to the latter two types.” Id. at 163. In New
    Mexico, “the general rule [is] that one homicide by the acts of one defendant
    should result in one homicide conviction.” State v. Mann, 
    11 P.3d 564
    , 570
    (N.M. Ct. App. 2000). If we permitted the government to assimilate the state
    laws in this case, Ms. Christie would be subject to additional charges merely for
    committing the crime on a federal enclave, even though state law forms the basis
    of two of the underlying convictions.
    Indeed, the government’s actions here seem to violate the spirit of the law.
    The purpose of the ACA is to allow prosecutors the option of using state law
    when federal law does not punish the specific crime at issue. It strikes me as
    disingenuous for prosecutors to argue that they need to borrow state law because
    federal law does not cover this conduct within the meaning of the ACA, but then
    prosecute on those “insufficient” federal charges as well—even though a state
    conviction for both murder and child abuse resulting in death in New Mexico
    would not be upheld because the state legislature intended these to be alternative
    charges.
    -5-
    II
    The government makes two arguments in response. First, the government
    argues that the state laws and the federal laws do not punish approximately the
    same behavior, which would argue in favor of assimilation. Second, the
    government argues that Lewis hinged on Congress’s efforts to limit the crimes for
    which the death penalty could be imposed. Although these arguments have some
    merit, neither of them is ultimately persuasive.
    While I agree with the government that these statutes no doubt cover
    different conduct, that alone is not dispositive. As the Supreme Court noted in
    Lewis:
    We concede at the outset the Government’s claim
    that the two statutes cover different forms of behavior.
    The federal second-degree murder statute covers a wide
    range of conduct; the Louisiana first-degree murder
    provision focuses upon a narrower (and different) range
    of conduct. We also concede that, other things being
    equal, this consideration argues in favor of assimilation.
    Yet other things are not equal; and other features of the
    federal statute convince us that Congress has intended
    that the federal murder statute preclude application of a
    first-degree murder statute such as Louisiana’s to a
    killing on a federal enclave.
    523 U.S. at 169. The Court then concluded that the state law was not assimilated.
    Likewise, while the federal and state statutes in this case cover different conduct,
    the other factors are paramount here. Congress has enacted a full set of homicide
    laws—including a first-degree murder statute that penalizes some forms of child
    -6-
    abuse. Further, it is unlikely Congress intended to grant federal prosecutors the
    ability to secure convictions based on state law using the ACA that state
    prosecutors could not secure in state court.
    As for the second argument, the Lewis court did, of course, discuss the
    death penalty. The Court supported its conclusion that Louisiana’s first-degree
    murder statute was not assimilated by noting that the Louisiana statute could have
    punished the conduct in question with the death penalty, while the federal murder
    statutes would not. The Court concluded that it would be unusual for Congress to
    extend the death penalty to additional crimes using the ACA given the effort
    Congress had already expended to carefully list and circumscribe the murder
    crimes that could be punished with the death penalty. This does not, however,
    fully distinguish Lewis, because Lewis does not hinge on the death penalty
    argument. As discussed above, most of Lewis’s reasoning is still relevant to this
    case, and should control. And here, it should preclude assimilation.
    III
    Therefore, like the majority, I would reject the government’s cross-appeal
    and also conclude the district court was ultimately correct in vacating the state
    law homicide convictions. However, my approach to the question of assimilation
    raises the question of whether the district court should have dismissed the state
    law homicide charges before they even went to the jury. Again, though, I agree
    with the majority that we can avoid resolving that vexing question in this case.
    -7-
    As regards Ms. Christie’s assertion that the state law homicide charges should not
    have gone to the jury, I agree with the majority that any error in permitting these
    charges to go to the jury was ultimately harmless.
