    GINSBURG, Senior Circuit Judge: At issue in this suit is
    the constitutionality of certain gun laws enacted by the
    District of Columbia. The district court determined as a
    matter of law that the District’s efforts “to combat gun
    violence and promote public safety” by means of its
    registration laws were “constitutionally permissible.” Heller
    v. District of Columbia, 
    45 F. Supp. 3d 35
    , 38 (D.D.C. 2014).
    Before this court, Dick Anthony Heller and his co-appellants
    challenge both the district court’s admission of, and its
    reliance upon, certain expert reports proffered by the District
    and the final order denying Heller’s and granting the
    District’s motion for summary judgment.
    We hold the district court’s admission of the challenged
    expert reports was not an abuse of discretion. We affirm in
    part and reverse in part the district court’s judgment in favor
    of the District.
    4
    I. Background
    In District of Columbia v. Heller (Heller I) the Supreme
    Court held the District of Columbia’s “prohibition of
    handguns held and used for self-defense in the home” was
    unconstitutional. 
    554 U.S. 570
    , 636 (2008). Immediately
    thereafter, the D.C. City Council revised the District’s gun
    laws by enacting the Firearms Registration Amendment Act
    of 2008 (FRA). D.C. Law 17-372.
    The FRA created a “new scheme for regulating firearms.”
    Heller v. District of Columbia, 
    670 F.3d 1244
    , 1248 (D.C.
    Cir. 2011) (Heller II). With limited exceptions, the FRA
    required the registration of all firearms in the District. D.C.
    Code § 7-2502.01. The law also imposed various conditions
    upon the registration of a firearm and limited the persons
    eligible to register a firearm by excluding, for example,
    individuals who within the prior five years had been
    convicted of certain drug or violent crimes or had a severe
    mental health problem, and individuals under the age of 18.
    
    Id. § 7-2502.03-.07.
    In addition, the FRA required the gun
    owner to renew the registration of his firearm(s) every three
    years, 
    id. § 7-2502.07a,
    and prohibited registration — and
    hence possession — of certain firearms, such as short-
    barreled rifles and assault weapons. 
    Id. § 7-2502.02.
    In July 2008 Heller filed suit challenging the District’s
    new registration scheme as inconsistent with the Second
    Amendment to the Constitution of the United States. The
    district court granted summary judgment to the District and
    Heller appealed.
    On that appeal, we upheld the constitutionality of the
    District’s “basic registration requirement,” insofar as that
    requirement pertained to handguns. Heller 
    II, 670 F.3d at 5
    1254-55. We also upheld the portion of the FRA prohibiting
    registration, and therefore possession, of assault weapons and
    magazines with a capacity in excess of 10 rounds. 
    Id. at 1247-48,
    1264.
    We reserved judgment as to the constitutionality of the
    District’s basic registration requirement for long guns, the
    conditions under which a registration certificate would be
    issued, and the duration for which such a certificate would be
    valid. 
    Id. at 1255,
    1258-60. We held that both the basic
    registration requirement for long guns, if not de minimis, and
    the conditions for registration were subject to intermediate
    scrutiny, and that the record as it then stood was not sufficient
    for us to evaluate whether those laws were narrowly tailored
    to serve an important governmental interest. 
    Id. at 1258.
    We
    therefore remanded the case to the district court for further
    evidentiary proceedings. 
    Id. at 1260.
    Subsequently, the D.C. Council enacted the Firearms
    Amendment Act of 2012, D.C. Law 19-170, which repealed
    certain of the conditions for registration, such as the
    requirement that a pistol be submitted for ballistic
    identification as part of the registration process, and reduced
    the burden upon registrants imposed by other provisions.
    Heller then filed an amended complaint to take account of
    these legislative changes.
    During discovery, Heller and the District offered the
    opinion testimony of, respectively, one and four expert
    witnesses. Heller v. District of 
    Columbia, 45 F. Supp. 3d at 40
    (Heller III). Largely upon the basis of their testimony, the
    district court entered summary judgment for the District.
    On this appeal, Heller argues the district court erred by
    admitting the opinion testimony of three of the District’s four
    6
    expert witnesses. In addition, Heller argues the district court
    erred in upholding as constitutional: (1) the basic registration
    requirement as it pertains to long guns, D.C. Code § 7-
    2502.01(a); (2) the requirement that one appear in person to
    register a firearm and be fingerprinted and photographed, 
    id. § 7-2502.04;
    (3) the requirement that the registrant bring with
    him the firearm to be registered, which requirement the
    Metropolitan Police Department (MPD) may or may not
    invoke as to a particular individual, 
    id. § 7-2502.04(c);
    (4) the
    expiration of the registration after three years, 
    id. § 7-
    2502.07a; (5) the imposition of certain fees for registration,
    
    id. § 7-
    2502.05(b); (6) the requirements that a registrant
    complete a firearms safety and training course or provide
    evidence of another form of training and that the registrant
    pass a test to demonstrate his knowledge of the District’s
    firearms laws, 
    id. §§ 7-2502.03(a)(13),
    7-2502.03(a)(10); and
    (7) the prohibition on registration of more than one pistol per
    person in any 30-day period, 
    id. § 7-
    2502.03(e).
    II. Analysis
    We first address the district court’s admission of the
    challenged expert reports and related testimony. We then turn
    to Heller’s constitutional challenges.
    A. The expert reports and testimony
    Heller moved to strike three of the four expert reports
    offered by the District during discovery, viz., those of Cathy
    Lanier, the Chief of the MPD, and of Mark Jones and Joseph
    Vince, Jr., both former agents of the Bureau of Alcohol,
    Tobacco, Firearms and Explosives (ATF), but not that of
    Daniel Webster, Director of the Johns Hopkins Center for
    Gun Policy. Heller argued the expert reports “fall short of the
    disclosure requirements under FED. R. CIV. P. 26(a) and that
    7
    their proposed testimony [was] too unreliable to be admitted
    under FED. R. EVID. 702.” The district court denied Heller’s
    motion.
    On appeal, Heller renews both arguments. We review the
    district court’s admission of expert testimony for abuse of
    discretion, whether that admission is challenged under the
    rules of evidence or under the rules of procedure. United
    States v. Day, 
    524 F.3d 1361
    , 1367 (D.C. Cir. 2008). We
    conclude that the district court did not abuse its discretion in
    admitting the challenged testimony.
    1. Federal Rule of Civil Procedure 26
    Federal Rule of Civil Procedure 26(a)(2)(B) provides that
    an expert witness must submit a written report containing,
    among other things, “a complete statement of all opinions the
    witness will express and the basis and reasons for them,” as
    well as “the facts or data considered by the witness in forming
    them.” A party who fails to comply with Rule 26(a)(2)(B)
    generally may not use that witness “to supply evidence on a
    motion … unless the failure was substantially justified or is
    harmless.” FED. R. CIV. P. 37(c)(1).
    The purpose of the rule is to avoid “unfair surprise to the
    opposing party.” Muldrow ex rel. Estate of Muldrow v. Re-
    Direct, Inc., 
    493 F.3d 160
    , 167 (D.C. Cir. 2007) (citation and
    internal quotation marks omitted). Admitting a report with an
    omission that does not cause “unfair surprise” we deem
    harmless. 
    Id. As the
    district court noted, each of the challenged expert
    reports contained an explicit statement as to the basis for that
    witness’s opinion, to wit, that his or her report was based “on
    my experience, my review of numerous studies and books, the
    8
    District of Columbia’s firearms laws and regulations, and
    discovery materials from this case made available to me.” In
    addition each report recounts in detail the expert’s relevant
    experience. The district court stated:
    Plaintiffs have had an opportunity to depose these
    experts and examine more fully the bases for their
    opinions ….       Where Defendants have provided
    adequate notice of the opinions they expect these
    experts to offer and Plaintiffs have had and continue to
    have opportunities to challenge these conclusions, the
    goals of Rule 26(a) are satisfied, and there is no basis
    for striking the reports and preventing these experts
    from testifying.
    Heller v. District of Columbia, 
    952 F. Supp. 2d 133
    , 139
    (D.D.C. 2013).
    The district court did not abuse its discretion in so
    holding. The experts’ reports adequately established the
    bases for the opinions they expressed in the reports and in
    their declarations. Heller had the opportunity to probe the
    bases for the witnesses’ opinions when he deposed them.
    2. Federal Rule of Evidence 702
    Rule 702 provides:
    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:
    (a)    the expert’s scientific, technical, or other
    specialized knowledge will help the trier of
    9
    fact to understand the evidence or to determine
    a fact in issue;
    (b)     the testimony is based on sufficient facts or
    data;
    (c)     the testimony is the product of reliable
    principles and methods; and
    (d)     the expert has reliably applied the principles
    and methods to the facts of the case.
    FED. R. EVID. 702.
    In Daubert v. Merrell Dow Pharmaceuticals, the
    Supreme Court held Rule 702 requires courts to ensure that
    expert testimony is “not only relevant, but reliable.” 
    509 U.S. 579
    , 589 (1993); see also Kumho Tire Co. v. Carmichael, 
    526 U.S. 137
    , 149 (1999) (noting that “Daubert’s general
    principles apply” not just to scientific testimony but to all “the
    expert matters described in Rule 702”). Therefore, courts are
    obligated to “determine whether [expert] testimony has a
    reliable basis in the knowledge and experience of [the
    relevant] discipline.” Kumho 
    Tire, 526 U.S. at 149
    (second
    alteration in original) (citation and internal quotation marks
    omitted). Nonetheless, the Supreme Court has said “the trial
    judge must have considerable leeway in deciding in a
    particular case how to go about determining whether
    particular expert testimony is reliable.” 
    Id. at 152.
    In this case the district court reasoned:
    [I]t appears here that the opinion evidence is
    connected to the existing facts – the registration
    requirements and the state of gun violence in the
    10
    District – by a methodology precisely contemplated by
    Daubert and Rule 702: each expert’s professional
    judgment obtained through long experience in the
    field. Each of the reports specifically identifies this
    experience as being the basis for the opinions
    proffered, and each provides some justification – in
    the form of information gained from the expert’s
    relevant experience – for those opinions.
    Heller v. District of 
    Columbia, 952 F. Supp. 2d at 142
    .
    As the district court rightly suggested, each of the
    challenged experts has decades of relevant experience. Still,
    the Advisory Committee notes to Rule 702 provide that a
    witness who is “relying solely or primarily on experience …
    must explain how that experience leads to the conclusion
    reached, why that experience is a sufficient basis for the
    opinion, and how that experience is reliably applied to the
    facts.” In this case the experts’ explanation of the connection
    between their experience and their conclusions was
    sometimes fatally sparse. Likewise, the district court failed
    meaningfully to evaluate the factual bases for the experts’
    opinions, noting only that they were supported by “some
    justification — in the form of information gained from the
    expert’s relevant experience.”
    As this court has noted, however, the “admission of
    [expert] testimony does not constitute an abuse of discretion
    merely because the factual bases for an expert’s opinion are
    weak.” Joy v. Bell Helicopter Textron, Inc., 
    999 F.2d 549
    ,
    567 (D.C. Cir. 1993). Nor is this a case in which the experts’
    reports consisted of “subjective belief or unsupported
    speculation,” which the rules of evidence preclude. 
    Id. at 570
    (citation and internal quotation marks omitted).
    11
    In addition to invoking his or her generalized
    “experience,” each expert claimed to have relied upon
    specific news stories, academic studies, or other research in
    forming an opinion. Moreover, each of the three experts was
    in a position to state whether the cited materials comported
    with his or her personal experience.
    In light of the challenged experts’ substantial relevant
    experience and the sources they cited in support of their
    conclusions — the above-noted stories, studies, and research
    — we hold the district court did not abuse its discretion in
    admitting the challenged expert reports and the subsequent
    expert declarations. Rather, as the district court noted,
    Heller’s “concerns about the conclusions [to which] these
    experts’ experience led them … go to the weight of the
    testimony,” not its admissibility. Heller v. District of
    
    Columbia, 952 F. Supp. 2d at 142
    .
    B. The constitutional challenges
    We review the district court’s summary judgment
    determination de novo, considering the evidence in the light
    most favorable to the non-moving party, i.e., Heller. See
    Ayissi-Etoh v. Fannie Mae, 
    712 F.3d 572
    , 576 (D.C. Cir.
    2013).
    In Heller II, we adopted a two-step approach to
    determining the constitutionality of the District’s gun
    registration laws: “We ask first whether a particular provision
    impinges upon a right protected by the Second Amendment; if
    it does, then we go on to determine whether the provision
    passes muster under the appropriate level of constitutional
    
    scrutiny.” 670 F.3d at 1252
    . We determined that level was
    intermediate scrutiny. 
    Id. at 1252-53.
                                   12
    For a challenged provision to survive intermediate
    scrutiny, the District has to show, first, that it “promotes a
    substantial governmental interest that would be achieved less
    effectively absent the regulation,” and second, that “the means
    chosen are not substantially broader than necessary to achieve
    that interest.” 
    Id. at 1258
    (quoting Ward v. Rock Against
    Racism, 
    491 U.S. 781
    , 782-83 (1989)). To meet the first
    requirement, the District must demonstrate that the harms to
    be prevented by the regulation “are real, not merely
    conjectural, and that the regulation will in fact alleviate these
    harms in a direct and material way.” Turner Broad. Sys., Inc.
    v. FCC, 
    512 U.S. 622
    , 662-64 (1994) (Turner I). We do not,
    however, review de novo the District’s evidence of the harm
    to be prevented and the likely efficacy of the regulation in
    preventing that harm. See 
    id. at 666.
    Rather, it is our remit to
    determine only whether the District “has drawn reasonable
    inferences based on substantial evidence.” 
    Id. If it
    has done
    so, and if the means chosen are not overbroad, then “summary
    judgment … is appropriate regardless of whether the evidence
    is in conflict.” Turner Broad. Sys., Inc. v. FCC, 
    520 U.S. 180
    ,
    185, 195-96, 211 (1997) (Turner II); see also Heller 
    II, 670 F.3d at 1263
    (upholding the District’s ban on assault weapons
    on the basis that “the evidence demonstrates a ban on assault
    weapons is likely to promote the Government’s interest in
    crime control”).
    1. Impingement
    In Heller II we held the basic registration requirement as
    applied to handguns did not impinge upon the Second
    Amendment and was therefore 
    constitutional. 670 F.3d at 1254-55
    (“[T]he basic requirement to register a handgun is
    longstanding in American law …. Therefore, we presume the
    District’s basic registration requirement including the
    submission of certain information does not impinge upon the
    13
    right protected by the Second Amendment. Further, we find
    no basis in either the historical record or the record of this
    case to rebut that presumption.”) (citations omitted); see also
    Heller 
    I, 554 U.S. at 626-27
    & n.26 (“longstanding” firearm
    regulations are “presumptively lawful”). We left open the
    question whether requiring the registration of long guns
    impinges upon the Second 
    Amendment. 670 F.3d at 1255
    n.**; see also D.C. Code § 7-2502.01(a). We now hold it
    does not.
    Requiring the registration of handguns is legally different
    from requiring the registration of long guns only in that “basic
    registration of handguns is deeply enough rooted in our
    history to support the presumption that [it] is constitutional,”
    Heller 
    II, 670 F.3d at 1253
    ; the registration requirement for
    long guns lacks that historical pedigree. 
    Id. at 1255.
    Even absent the presumption that attends the pedigree,
    however, the basic registration requirement as applied to hand
    guns falls into the category of requirements that are “self-
    evidently de minimis, for they are similar to other common
    registration or licensing schemes, such as those for voting or
    for driving a car, that cannot reasonably be considered
    onerous.” 
    Id. at 1254-55.
    On Heller’s previous appeal, we
    were unable to determine whether requiring the registration of
    long guns is similarly a de minimis burden because the record
    was “devoid of information concerning the application of
    registration requirements to long guns.” 
    Id. at 1255
    n.**. We
    therefore allowed Heller, during the discovery proceedings on
    remand, the opportunity to introduce evidence that might
    differentiate the registration requirement for long guns from
    other registration requirements that undoubtedly entail a de
    minimis burden upon a constitutional right. As the district
    court subsequently determined, however, Heller offered no
    evidence distinguishing the basic registration requirement as
    14
    applied to long guns. See Heller 
    III, 45 F. Supp. 3d at 51
    .
    Indeed, he did not even argue the point. 1
    Because the burden of the basic registration requirement
    as applied to long guns is de minimis, it does not implicate the
    second amendment right. Heller 
    II, 670 F.3d at 1255
    ; see
    also Justice v. Town of Cicero, 
    577 F.3d 768
    , 773-75 (7th Cir.
    2009) (holding local ordinance “requiring the registration of
    all firearms” is consistent with the Supreme Court’s ruling in
    Heller I). It is therefore constitutional.
    1
    In his reply brief in this court, Heller argued for the first time that
    the registration requirement impinges upon the Second Amendment
    right to bear arms because a person can “go to prison and receive a
    lifetime ban on possession of firearms for failure to register or
    reregister.” See D.C. Code §§ 7-2502.03, 7-2507.06, 7-2502.08
    (providing generally violation of the registration requirements may
    result in fines, imprisonment, and ineligibility to register weapons
    in the future). This assertion, however, is too little, too late. It
    comes too late because we do not ordinarily notice an argument that
    first appears in a reply brief. See Gunpowder Riverkeeper v. FERC,
    No. 14-1062, 
    2015 WL 4450952
    , at *5 (D.C. Cir. July 21, 2015)
    (“[A]rguments not clearly raised in a party’s opening brief are
    generally considered to be forfeit”). In any event, it is too little
    because in Heller II we instanced other licensing schemes we think
    impose a de minimis burden notwithstanding that failure to comply
    with those schemes may result in criminal penalties; so it is with
    the basic registration requirement for long guns. See Heller 
    II, 670 F.3d at 1254-55
    (describing licensing schemes “such as [that] for
    … driving a car” as “self-evidently de minimis”); D.C. Code § 50-
    1403.01(e) (providing that an individual found guilty of “operating
    a motor vehicle in the District” while that person’s license is
    “revoked or suspended” may be fined or imprisoned for up to one
    year).
    15
    The additional registration requirements, however, cannot
    be said to be de minimis. In Heller II, we held the additional
    requirements, as they then stood, “affect[ed] the Second
    Amendment right because they [we]re not de minimis” —
    that is, they “ma[d]e it considerably more difficult for a
    person lawfully to acquire and keep a firearm … for the
    purpose of self-defense in the home.” 
    Id. at 1255.
    The
    subsequent repeal of some of those requirements and the
    amendment of others somewhat reduced the burden imposed
    upon District residents’ exercise of their Second Amendment
    rights. The District does not go so far as to argue, however,
    that the amended requirements are de minimis. Those
    requirements are therefore subject to intermediate scrutiny.
    2. Intermediate scrutiny
    We previously identified two substantial governmental
    interests served by the registration requirements enacted by
    the District: (1) protecting police officers by enabling them to
    determine, in advance, whether guns may be present at a
    location to which they are called and (2) aiding in crime
    control. Heller 
    II, 670 F.3d at 1258
    . On remand, the District
    recharacterized the second interest as a broader interest in
    “promoting public safety.” Heller 
    III, 45 F. Supp. 3d at 49
    .
    On appeal, the District identifies more particularly its interest
    in “protecting police officers” and reiterates its interest in
    “promoting public safety” generally.
    Heller does not dispute that these are substantial
    governmental interests. Rather, he challenges the closeness of
    the fit between the asserted interests and the various
    registration requirements. We agree with Heller that the
    District has not offered substantial evidence from which one
    could draw a reasonable conclusion that the challenged
    requirements will protect police officers; but we think the
    16
    District has pointed to substantial evidence that some of the
    requirements — but not others — will promote public safety.
    a. Police protection
    Heller argues the registration requirements do not
    advance the District’s interest in protecting the police because
    MPD officers very rarely check the registration records in
    responding to a call, conducting an investigation, or executing
    a search warrant. The District responds that although the
    “MPD does not routinely check registration records prior to
    responding to a call for service … such a check is a tool
    available for use in appropriate circumstances.” It is
    undisputed that such checks have taken place, albeit rarely.
    Therefore, the question remains whether that “tool”
    promotes the District’s asserted interest in police protection.
    Discovery subsequent to our decision in Heller II indicates it
    does not.
    According to the deposition testimony of an MPD officer,
    District police “are trained to treat situations where there
    might be a crime in progress or domestic dispute or some
    other situation possibly involving violence as always having a
    potential to have a dangerous weapon present.” Further, one
    of the District’s expert witnesses stated that if the registration
    system indicated no weapon was present at an address, then
    officers “would continue to exercise caution.” The best the
    District’s expert could offer was that positive confirmation of
    a gun might raise officers’ “caution level … that much
    higher.”
    The testimony of the District’s own witnesses, therefore,
    indicates that the records established via the registration
    requirements, when queried at all, have little to no effect upon
    17
    the conduct or safety of police officers. In light of this
    additional evidence, we agree with the statement of our
    colleague in Heller II that the asserted interest in police
    protection “leaves far too many false negatives to satisfy …
    intermediate 
    scrutiny.” 670 F.3d at 1295
    (Kavanaugh, J.,
    dissenting).
    b. Public safety
    Drawing directly upon the Report of the Judiciary
    Committee of the D.C. Council with respect to the Firearms
    Amendment Act of 2012, the District claims the various
    registration requirements advance its interest in public safety
    by “distinguishing criminals from law-abiding citizens,
    enabling police to arrest criminals immediately, facilitating
    enforcement against prohibited persons obtaining or
    continuing to possess firearms, reducing gun trafficking, and
    increasing the difficulty for criminals to acquire guns.” We
    next address whether the District has, with regard to each
    challenged registration provision, offered substantial evidence
    from which it could reasonably have concluded the provision
    will mitigate various threats to public safety “in a direct and
    material way,” Turner 
    I, 512 U.S. at 664
    , whether in one of
    the ways anticipated by the D.C. Council or otherwise.
    i.      In-person appearance, fingerprinting, and
    photographing, D.C. Code § 7-2502.04
    The District has presented substantial evidence from
    which it could conclude that fingerprinting and photographing
    each person registering a gun promotes public safety by
    facilitating identification of a gun’s owner, both at the time of
    registration and upon any subsequent police check of the
    gun’s registration. The requirement that registrants appear in
    18
    person is necessary in order for a photograph and fingerprints
    to be taken.
    First, the fingerprinting requirement: The Report of the
    Committee on the Judiciary stated that “[t]he initial
    fingerprinting requirement is fundamental for the [MPD] to
    fulfill its public safety obligations in registering firearms —
    being able to screen the registrant to ensure that he or she is
    not disqualified from possessing a firearm.” In support of this
    assertion, the District points to the testimony of Chief Lanier,
    who said “[u]sing biometrics [i.e., fingerprints] to positively
    identify an individual is far more effective than relying simply
    on a name and social security number.” Chief Lanier
    reiterates this conclusion in her expert declaration, and it is
    echoed in Webster’s expert declaration.
    In addition, the District points to evidence suggesting
    background checks using fingerprints are more reliable than
    background checks conducted without fingerprints, which are
    more susceptible to fraud. Specifically, the District points to
    an investigation conducted by the U.S. Government
    Accountability Office, in which five “agents acting in an
    undercover capacity used … counterfeit driver’s licenses in
    attempts to purchase firearms from gun stores and pawnshops
    that were licensed by the federal government to sell firearms.”
    GAO-01-427, FIREARMS PURCHASED FROM FEDERAL
    FIREARM LICENSEES USING BOGUS IDENTIFICATION 2 (2001).
    Those attempts were, without exception, successful. 
    Id. at 2-
    3. The report concluded that federal background checks
    conducted by the firearm dealers “cannot ensure that the
    prospective purchaser is not a felon or other prohibited person
    19
    whose receipt and possession of a firearm would be
    unlawful.” 
    Id. at 2.
    2
    Heller argues the District has not experienced a problem
    with fraud in the registration of firearms. He also implies the
    problem is unlikely to arise, given the increased difficulty of
    manufacturing fraudulent identification documents today, as
    compared to 2001, when the GAO concluded its investigation.
    Even if this is true, however, a prophylactic disclosure
    measure such as the one at issue here survives intermediate
    scrutiny if the deterrent value of the measure will materially
    further an important governmental interest. See Barry v. City
    of New York, 
    712 F.2d 1554
    , 1559-61 (2d Cir. 1983)
    (upholding under intermediate scrutiny a law requiring
    financial disclosures by certain publicly employed individuals
    in the face of a right-to-privacy challenge on the basis that it
    could “help deter corruption,” despite a “virtually corruption-
    free history” (citation and internal quotation marks omitted)).
    The GAO study indicates the fingerprinting requirement
    would, indeed, help to deter and detect fraud and thereby
    prevent disqualified individuals from registering firearms.
    Regarding the requirement of a photograph: The
    Committee on the Judiciary emphasized “the importance of a
    registrant being able to present a registration certificate with a
    photograph, so police can quickly identify whether and to
    2
    The states in which the GAO conducted its study had adopted the
    National Instant Criminal Background Check System (NICS), see
    18 U.S.C. § 922(t), under which, then as now, the following
    information is required of each individual who undergoes a NICS
    check: (1) name, (2) sex, (3) race, (4) date of birth, and (5) state of
    residence. 28 C.F.R. § 25.7. A dealer may, in addition, report the
    purchaser’s Social Security or other identifying number and
    physical description. 
    Id. 20 whom
    the firearm has been legally registered.”                The
    Committee pointed to the testimony of Chief Lanier, who
    asserted that “a certificate with a photo helps to quickly and
    safely communicate” the fact of registration to police officers,
    which, “in turn, helps to keep both the officer and the
    registrant safe.” Heller, while maintaining that photographing
    a registrant will not deter fraud, does not contest that
    photographic confirmation of a registrant’s identity would be
    beneficial to public safety when the police encounter an
    armed registrant. See D.C. Code § 7-2502.08(c) (“Each
    registrant shall have in the registrant’s possession, whenever
    in possession of a firearm, the registration certificate, or exact
    photocopy thereof, for such firearm, and exhibit the same
    upon the demand of a member of the [MPD], or other law
    enforcement officer”).
    For the foregoing reasons, we believe the District has
    adduced substantial evidence from which it reasonably could
    conclude that fingerprinting and photographing registrants
    will directly and materially advance public safety by
    preventing at least some ineligible individuals from obtaining
    weapons and, more important, by facilitating identification of
    the owner of a registered firearm during any subsequent
    encounter with the police. Those requirements are therefore
    not unconstitutional.      The additional requirement that
    registrants appear in person to be photographed and
    fingerprinted is but a corollary necessary to implement those
    requirements. See Heller 
    II, 670 F.3d at 1249
    n.* (noting that
    administrative provisions “incidental to the underlying
    regime” are “lawful insofar as the underlying regime is
    lawful”).
    21
    ii.     Bringing the firearm, D.C. Code § 7-
    2502.04(c)
    The District argues that the “requirement that the firearm
    be made available for inspection allows MPD to verify that
    the application information is correct and that the firearm has
    not been altered or switched with another firearm.” The
    District, however, has offered no evidence — let alone
    substantial evidence — from which it can be inferred that
    verification will promote public safety. The district court
    acknowledged as much when it noted that not one of the
    District’s four experts “specifically addresse[d] the
    requirement that registrants bring the gun to be registered
    with them.” Heller 
    III, 45 F. Supp. 3d at 59
    . The district
    court nonetheless deemed it a “common-sense inference” that
    “if in-person appearance is necessary to verify the identity of
    the registrant, then physically bringing the gun is similarly
    necessary to verify the character of the registered weapon.”
    
    Id. Yet common
    sense suggests a person would not go to the
    trouble of obtaining a registration certificate for a weapon
    other than a weapon in his possession. On the contrary,
    common sense suggests that bringing firearms to the MPD
    would more likely be a threat to public safety; as Heller
    maintains, there is a “risk that the gun may be stolen en route
    or that the [would-be registrant] may be arrested or even shot
    by a police officer seeing a ‘man with a gun’ (or a gun case).”
    iii.    Re-registration, D.C. Code § 7-2502.07a
    The District has offered three justifications for the
    requirement that a gun owner re-register his firearm every
    three years. None is supported by substantial evidence from
    which the District could reasonably have concluded that
    requiring re-registration would advance an important
    governmental interest.
    22
    First, the District’s experts argued that re-registration
    “will improve public safety by making sure that, in the time
    since [the gun owner] first registered, [he has] not fallen into a
    category of persons prohibited from owning a firearm.”
    Heller 
    III, 45 F. Supp. 3d at 67-68
    . As Heller rightly points
    out, however, “District officials and experts conceded [that]
    background checks could be conducted at any time without
    causing the registrations to expire.” The re-registration
    requirement cannot survive intermediate scrutiny on the
    (dubious) basis that it will make this task easier. Cf.
    McCullen v. Coakley, 
    134 S. Ct. 2518
    , 2540 (2014) (“To meet
    the requirement of narrow tailoring, the government must
    demonstrate that alternative measures that burden
    substantially less speech would fail to achieve the
    government’s interests, not simply that the chosen route is
    easier”).
    Second, the District argues triennial re-registration will
    help to maintain the accuracy of the registration database.
    This seems self-evidently true, but it is far from an adequate
    reason for burdening every gun owner when there is already a
    requirement that gun owners report relevant changes in their
    information, such as a new address. D.C. Code § 7-2502.08
    (requiring such reporting). To the extent that a gun owner’s
    death or disposal of a registered gun is a fact of which the
    District should be aware, the District’s registration
    requirements as applied to any new owner within the District
    should satisfy that interest.
    Third, the District argues that it has “an interest in its
    residents verifying the whereabouts of their firearms” in order
    “to determine when firearms have been lost or stolen.”
    District law, however, separately requires a gun owner to
    report the loss or theft of a weapon “immediately upon
    23
    discovery” of the loss or theft, and imposes a monetary
    penalty for failure to do so. 
    Id. § 7-2502.08(a)(1).
    In
    contrast, the re-registration provision imposes no penalty for
    failure to re-register except the revocation of one’s
    registration certificate, but a person whose weapon has been
    lost or stolen no longer has need of a certificate. Although the
    District fails to make the argument express in its brief, the
    report of its Committee on the Judiciary, on which the brief
    relies in general, asserted that the re-registration provision
    may complement the loss-reporting provision because it
    “likely causes the owner to look for his or her gun if it hasn’t
    been used” for a while, but that is mere speculation. The re-
    registration process requires only that a gun owner affirm that
    he still has the registered weapon; it does not require the gun
    owner physically to examine the weapon. See 
    id. § 7-
    2502.07a. Therefore, there is no reason to believe that an
    owner who does not suspect his gun has been lost or stolen is
    likely to look for the registered weapon prior to re-registering
    it.
    iv.     Fees, D.C. Code § 7-2502.05
    Heller argues “[t]he District may not condition exercise
    of a fundamental constitutional right on the creation of a
    burdensome registration regime and then justify imposing
    ‘administrative costs’ to pay for it.” He does not argue the
    registration fees of $13 per firearm and $35 for fingerprinting,
    D.C. Mun. Regs. tit. 24, § 2320.3(c)(3), are unreasonably
    high.
    As we already said in Heller II, “administrative …
    provisions incidental to the underlying regime” — which
    include reasonable fees associated with registration — are
    lawful insofar as the underlying regime is 
    lawful. 670 F.3d at 1249
    n.*; see also Cox v. New Hampshire, 
    312 U.S. 569
    , 577
    24
    (1941) (holding, in response to a First Amendment challenge
    to a parade licensing statute, that a government may impose a
    fee “to meet the expense incident to the administration of the
    act and to the maintenance of public order in the matter
    licensed”); Kwong v. Bloomberg, 
    723 F.3d 160
    , 165–69 (2d
    Cir. 2013) (holding constitutional a $340 fee for a license to
    possess a handgun in one’s home). As such, reasonable fees
    associated with the constitutional requirements of registration
    and fingerprinting are also constitutional.
    v.      Education requirements, D.C. Code §§ 7-
    2502.03(a)(10), 7-2502.03(a)(13)
    The District has presented substantial evidence from
    which it could conclude that training in the safe use of
    firearms promotes public safety by reducing accidents
    involving firearms, but has presented no evidence from which
    it could conclude that passing a test of knowledge about local
    gun laws does so.           The safety training, therefore, is
    constitutional; the test of legal knowledge is not.
    Regarding the one-hour firearms safety course, available
    online or at the MPD, FIREARMS SAFETY TRAINING COURSE,
    https://dcfst.mpdconline.com/ (last visited Aug. 21, 2015), the
    District’s experts each testified to their belief in the value of
    training to prevent accidents. Heller responds that “the
    District’s experts cite no studies showing that mandatory
    training or testing in gun safety reduce unintentional
    discharges.” The District, however, need not present such
    evidence. Rather, the Supreme Court has “permitted litigants
    to justify … restrictions … based … on history, consensus,
    and simple common sense” when the three are conjoined. Cf.
    Lorillard Tobacco Co., 
    533 U.S. 525
    , 555 (2001) (internal
    quotation marks omitted). In this case, the District has
    offered anecdotal evidence showing the adoption of training
    25
    requirements “in most every law enforcement profession that
    requires the carrying of a firearm” and a professional
    consensus in favor of safety training. 3 Though its experts
    have characterized the training requirement as a matter of
    “common sense,” this is not a case in which the District has
    asked the court to rule upon the basis of “common sense”
    alone.
    None of the District’s experts, however, offers any reason
    to believe that knowledge of the District’s gun laws will
    promote public safety. Indeed, the closest the District’s
    experts came to addressing the subject was the statement by
    Chief Lanier that “in order to make registrants more clearly
    accountable under the law, it is important to be able to
    demonstrate that they were taught and aware of the
    requirements.”    This assertion, however, does not tie
    knowledge of the law to the District’s interest in public safety.
    Furthermore, even if acquiring knowledge of the law
    were demonstrably helpful, the imposition of a requirement
    that registrants prove their knowledge of the law on “a test
    prescribed by the Chief” is an additional burden, see D.C.
    Code § 7-2502.03(10), the utility of which is supported by no
    evidence whatsoever, not even anecdotal evidence.
    Moreover, only a few of the 15 questions in the test actually
    3
    J.A. 394 (Lanier declaration) (“California, Connecticut, Hawaii,
    Massachusetts, and Michigan all have laws requiring some sort of
    training or safety certification as part of the registration process,
    and other jurisdictions are considering instituting similar
    requirements”); J.A. 407 (Vince declaration) (stating that he “do[es]
    not know of one firearm expert or law enforcement trainer who has
    not strongly recommended attending and successfully passing a
    safety course prior to owning or using a firearm”).
    26
    prescribed by the Chief plausibly reflect a concern with public
    safety. 4
    Because the District has offered no evidence from which
    the court can infer it reasonably concluded that knowledge of
    its gun laws, as shown by passing its test, will promote public
    safety, on this record the requirement must be held
    constitutionally invalid.
    vi.     One-pistol-per-month rule, D.C. Code. § 7-
    2502.03(e)
    The District has not presented substantial evidence to
    support the conclusion that its prohibition on the registration
    of “more than one pistol per registrant during any 30-day
    period,” D.C. Code § 7-2502.03(e), “promotes a substantial
    governmental interest that would be achieved less effectively
    absent the regulation.” Heller 
    II, 670 F.3d at 1258
    (quoting
    Rock Against 
    Racism, 491 U.S. at 782-83
    ). It is therefore
    unconstitutional.
    The District argues that the limitation could reduce gun
    trafficking and that it would further promote public safety by
    limiting the number of guns in circulation, as the District
    “could reasonably conclude that more guns lead to more gun
    theft, more gun accidents, more gun suicides, and more gun
    crimes.”
    4
    Compare J.A. 834 (“When handling a firearm, you should always:
    (A) Treat it as if it is loaded; (B) Point it in a safe direction; (C)
    Both A and B”) with J.A. 834 (“To purchase ammunition in the
    District of Columbia you must have the following in your
    possession: (A) A U.S. Passport; (B) A valid firearm registration
    certificate; (C) A valid driver’s license”).
    27
    As for the District’s first argument, what little expert
    testimony it presented indeed indicates that limiting gun
    purchases in turn might limit trafficking in weapons. The
    experts’ conclusion that limiting gun registrations would
    likewise reduce trafficking is, however, unsupported by the
    evidence. For example, Chief Lanier stated “[s]tudies have
    shown that laws restricting the registration or purchase of
    multiple firearms in a given period are effective in disrupting
    illegal interstate trafficking of firearms.” Yet the only study
    she and the District’s other witnesses cited has nothing to do
    with “laws restricting registration,” as its title attests. See
    Douglas S. Weil & Rebecca C. Knox, Effects of Limiting
    Handgun Purchases on Interstate Transfer of Firearms, 275
    J. AM. MED. ASS’N 1759 (1996). One of the experts also
    testified from his own observation that when Virginia limited
    firearm purchases to one every 30 days, fewer guns bought in
    Virginia were used in crimes committed in the District;
    traffickers, he observed, instead sourced more guns through
    straw purchasers in Maryland. But even if this is true, the
    suggestion that a gun trafficker would bring fewer guns into
    the District because he could not register more than one per
    month there lacks the support of experience and of common
    sense.      Indeed, as Heller notes, even Chief Lanier
    acknowledged that the efficacy of purchasing limitations in
    preventing trafficking may have little bearing upon the
    efficacy of registration limitations in doing so.
    As for the District’s second argument, one of its experts
    testified that, in his opinion, “the most effective method of
    limiting misuse of firearms, including homicide, suicide, and
    accidental injuries, is to limit the number of firearms present
    in a home.” Accepting that as true, however, it does not
    justify restricting an individual’s undoubted constitutional
    right to keep arms (plural) in his or her home, whether for
    self-defense or hunting or just collecting, because, taken to its
    28
    logical conclusion, that reasoning would justify a total ban on
    firearms kept in the home. See Parker v. District of
    Columbia, 
    478 F.3d 370
    , 400 (D.C. Cir. 2007), aff’d sub nom.
    Heller I (rejecting the District’s argument that a ban on one
    type of gun was constitutional because the “prohibition …
    [did] not threaten total disarmament” and noting that, if such
    argument were adopted “[i]t could similarly be contended that
    all firearms may be banned so long as sabers were
    permitted”).
    III. Conclusion
    For the reasons set forth above, the district court’s final
    order is AFFIRMED with respect to: the basic registration
    requirement as applied to long guns, D.C. Code § 7-
    2502.01(a); the requirement that a registrant be fingerprinted
    and photographed and make a personal appearance to register
    a firearm, D.C. Code § 7-2502.04; the requirement that an
    individual pay certain fees associated with the registration of
    a firearm, D.C. Code § 7-2502.05; and the requirement that
    registrants complete a firearms safety and training course,
    D.C. Code § 7-2502.03(a)(13). The district court’s order is
    REVERSED with respect to the requirement that a person
    bring with him the firearm to be registered, D.C. Code § 7-
    2502.04(c); the requirement that a gun owner re-register his
    firearm every three years, D.C. Code § 7-2502.07a; the
    requirement that conditions registration of a firearm upon
    passing a test of knowledge of the District’s firearms laws,
    D.C. Code § 7-2502.03(a)(10); and the prohibition on
    registration of “more than one pistol per registrant during any
    30-day period,” D.C. Code § 7-2502.03(e).
    So ordered.
    KAREN LECRAFT HENDERSON, Circuit Judge, concurring
    in part and dissenting in part: Regulating firearms in order to
    combat gun violence is a grave and complex task. The
    Supreme Court has made that legislative endeavor
    considerably more difficult by “tak[ing] certain policy choices
    off the table,” Dist. of Columbia v. Heller, 
    554 U.S. 570
    , 636
    (2008), and divining a new—and incomplete, see 
    id. at 635—
    definition of what the Second Amendment protects. Heller
    has “hand[ed] our democratic destiny to the courts” by
    inviting litigants to draw them into this political thicket.
    J. Harvie Wilkinson III, Of Guns, Abortions, and the
    Unraveling Rule of Law, 95 VA. L. REV. 253, 257 (2009).
    Happily, the “dominoes” have not fallen as quickly as
    expected, 
    Heller, 554 U.S. at 680
    (Stevens, J., dissenting), as
    most of our sister circuits have afforded a healthy level of
    deference to the law-makers. But today I fear the majority
    has initiated a retreat—at least in part—from the practice of
    restraint.
    My colleagues uphold six District of Columbia firearms
    laws but strike down four of them. Because I would uphold
    them all, I concur in part and dissent in part. In my view, the
    firearms laws that my colleagues invalidate (hereinafter, the
    remaining laws) satisfy intermediate scrutiny and,
    accordingly, I would affirm the well-reasoned decision of the
    district court. See 
    45 F. Supp. 3d 35
    (D.D.C. 2014).
    I. GENERAL PRINCIPLES
    Since the Supreme Court’s decision in Heller, this Court
    analyzes Second Amendment challenges under a two-step
    framework. First, we ask whether the law “impinges upon”
    Second Amendment rights, i.e., whether it has “more than a
    de minimis effect” on the right to keep and bear arms. Heller
    v. Dist. of Columbia (Heller II), 
    670 F.3d 1244
    , 1252–53
    (D.C. Cir. 2011). Second, if it does, we evaluate it under “the
    appropriate level of constitutional scrutiny.” 
    Id. at 1252.
    In
    2
    an earlier iteration of this case, we concluded that the
    challenged laws were “not de minimis” because they were
    “novel” and “ma[d]e it considerably more difficult for a
    person lawfully to acquire and keep a firearm . . . [for] self-
    defense in the home.” 
    Id. at 1255
    (citing 
    Heller, 554 U.S. at 630
    ). We also determined that intermediate scrutiny, not
    strict scrutiny, is the proper yardstick because the laws “do
    not severely limit the possession of firearms.” 
    Id. at 1257
    (alteration and quotation marks omitted).
    Intermediate scrutiny has its genesis in the Supreme
    Court’s equal protection and free speech jurisprudence. See,
    e.g., Craig v. Boren, 
    429 U.S. 190
    , 197 (1976); United States
    v. O’Brien, 
    391 U.S. 367
    , 377 (1968). It is a middle-ground
    approach that “offer[s] proper protection in the many
    instances in which a statute adversely affects constitutionally
    protected interests but warrants neither near-automatic
    condemnation (as ‘strict scrutiny’ implies) nor near-automatic
    approval (as is implicit in ‘rational basis’ review).” United
    States v. Alvarez, 
    132 S. Ct. 2537
    , 2552 (2012) (Breyer, J.,
    concurring in judgment). It essentially imposes a balancing
    test: the law is constitutional if “the governmental interest
    outweighs the burden [on constitutional rights] and cannot be
    achieved by means that do not infringe . . . rights as
    significantly.” Minneapolis Star & Tribune Co. v. Minn.
    Comm’r of Revenue, 
    460 U.S. 575
    , 585 n.7 (1983). “[T]he fit
    between the challenged regulation and the asserted objective
    need only be reasonable, not perfect,” Schrader v. Holder,
    
    704 F.3d 980
    , 990 (D.C. Cir. 2013) (alterations and quotation
    marks omitted), and the challenged law “need not be the least
    restrictive or least intrusive means of” achieving the
    government’s interest, Ward v. Rock Against Racism, 
    491 U.S. 781
    , 798 (1989).
    3
    The application of intermediate scrutiny “varies to some
    extent from context to context, and case to case.” Bartnicki v.
    Vopper, 
    200 F.3d 109
    , 124 (3d Cir. 1999), aff’d, 
    532 U.S. 514
    (2001). In this case and context, I believe the following
    principles should shape our analysis.
    First, the nature of firearms regulation requires ample
    deference to the legislature. We have previously held that, in
    the Second Amendment context, “we afford ‘substantial
    deference to the predictive judgments of [the legislature].’ ”
    
    Schrader, 704 F.3d at 990
    (quoting Turner Broad. Sys., Inc. v.
    FCC (Turner I), 
    512 U.S. 622
    , 665 (1994)). This is because
    “the legislature is far better equipped than the judiciary to
    make sensitive public policy judgments (within constitutional
    limits) concerning the dangers in carrying firearms and the
    manner to combat those risks.” 
    Id. (quotation marks
    omitted).
    Firearm policy is a “complex and dynamic” issue implicating
    “vast amounts of data” that the legislature is “far better
    equipped” to gather and analyze. Turner 
    I, 512 U.S. at 665
    –
    66. Such “information can be difficult to obtain and the
    impact of certain conduct difficult to assess,” Holder v.
    Humanitarian Law Project, 
    561 U.S. 1
    , 34 (2010), due to the
    different challenges facing different jurisdictions and the
    multiple factors that contribute to gun violence. Indeed, the
    data that does exist is either incomplete or influenced by
    partisanship:
    Few topics in the realm of U.S. justice and politics
    elicit a more polarizing response than that of gun
    control. . . . At the center of the debate is the
    fundamental question of whether firearms,
    specifically those owned and wielded by private
    citizens, do more harm than good in deterring violent
    crime. Despite intense scrutiny from so many fields,
    however, scholars have reached few solid
    4
    conclusions to date. The answers to even basic
    questions (who is victimized, how many are
    victimized, and at what cost are they victimized) are
    fiercely disputed, resulting in a nebulous yet hotly
    contested understanding of the interplay between
    guns and crime. . . . Data exists to support both
    sides; the difficulty lies in separating partisanship
    and underlying attitudes from empirical observation
    and objective analysis. In truth, the isolation of such
    objectivity may be a logical impossibility.
    II AMERICAN POLITICAL CULTURE: AN ENCYCLOPEDIA 505–
    06 (Michael Shally-Jensen ed. 2015). Intermediate scrutiny is
    a flexible framework that allows for different perspectives and
    a range of approaches to firearms regulation. See Fla. Bar v.
    Went For It, Inc., 
    515 U.S. 618
    , 632 (1995) (intermediate
    scrutiny does not require “the single best disposition” to
    problem); Time Warner Entm’t Co., L.P. v. United States, 
    211 F.3d 1313
    , 1322 (D.C. Cir. 2000) (“In applying intermediate
    scrutiny, we inquire ‘not whether Congress, as an objective
    matter, was correct . . . .’ ” (quoting Turner Broad. Sys., Inc.
    v. FCC (Turner II), 
    520 U.S. 180
    , 211 (1997) (emphasis
    added))).
    Indeed, judicial humility is especially important in the
    context of firearms regulation.          Although our Second
    Amendment precedent draws on First Amendment and
    voting-rights cases, see, e.g., Heller 
    II, 670 F.3d at 1257
    , the
    right to bear arms is meaningfully different from the rights to
    speak and vote. See Bonidy v. USPS, 
    790 F.3d 1121
    , 1126
    (10th Cir. 2015) (“The risk inherent in firearms and other
    weapons distinguishes the Second Amendment right from
    other fundamental rights that . . . can be exercised without
    creating a direct risk to others.”). At the same time, however,
    the Second Amendment is not a “second-class right,”
    5
    McDonald v. City of Chi., 
    561 U.S. 742
    , 780 (2010)
    (plurality), but the reality of gun violence means our
    constitutional analysis should incorporate deference to the
    legislature, see Humanitarian Law 
    Project, 561 U.S. at 34
    –
    36. One of our sister circuits said it well:
    This is serious business. We do not wish to be even
    minutely responsible for some unspeakably tragic act
    of mayhem because in the peace of our judicial
    chambers we miscalculated as to Second
    Amendment rights. . . . If ever there was an occasion
    for restraint, this would seem to be it.
    United States v. Masciandaro, 
    638 F.3d 458
    , 475–76 (4th Cir.
    2011).
    Second, the District of Columbia is sui generis. The
    plaintiffs are quick to point out that the District’s firearms
    laws are the toughest in the country and that a few have no
    parallel in other jurisdictions. But their point is unhelpful if
    the District is different from other jurisdictions. And it is.
    Most notably, the District is the seat of our national
    government. The record amply documents the unique
    security risks presented by a city full of high-level
    government officials, diplomats, monuments, parades,
    protests and demonstrations and, perhaps most pertinent,
    countless government buildings where citizens are almost
    universally prohibited from possessing firearms. See, e.g., 18
    U.S.C. § 930(a), (g)(1) (unlawful to “knowingly possess[] or
    cause[] to be present a firearm or other dangerous weapon in
    . . . a building or part thereof owned or leased by the Federal
    Government, where Federal employees are regularly present
    for the purpose of performing their official duties,” other than
    a Federal court facility); 
    id. § 930(e)(1)
    (unlawful to
    “possess[] or cause[] to be present a firearm or other
    6
    dangerous weapon in a Federal court facility”); 40 U.S.C.
    § 5104(e)(1)(A) (unlawful to “carry on or have readily
    accessible to any individual on the Grounds or in any of the
    Capitol Buildings a firearm”); see also 18 U.S.C.
    § 922(q)(2)(A) (making schools gun-free zones); Lanier Test.
    2–5. Indeed, walking around this town, one gets the
    impression that it is one big government building. Cf. 
    Heller, 554 U.S. at 626
    (“the right secured by the Second
    Amendment is not unlimited” and can give way to regulations
    of “the carrying of firearms in sensitive places” like
    “government buildings”). Although the Constitution does not
    stop at the Beltway, our analysis should account for the
    unique challenges that confront the District as it struggles to
    regulate firearms in our Nation’s capital. See City of L.A. v.
    Alameda Books, Inc., 
    535 U.S. 425
    , 439–40 (2002) (“A
    municipality considering an innovative solution may not have
    data that could demonstrate the efficacy of its proposal
    because the solution would, by definition, not have been
    implemented previously.”).
    II. THE REMAINING LAWS
    My colleagues strike down the District’s laws requiring
    registrants to pass a knowledge test, D.C. CODE § 7-
    2502.03(a)(10); present their firearms for inspection, 
    id. § 7-
    2502.04(c); renew their registration every three years, 
    id. § 7-
    2502.07a(a); and register no more than one pistol per month,
    
    id. § 7-
    2502.03(e). I address these laws seriatim and explain
    why, in my view, each one satisfies intermediate scrutiny.
    A. Knowledge Test
    Before an individual can register a gun, he must
    demonstrate his knowledge of the District’s firearms laws by
    passing a test. 
    Id. § 7-2502.03(a)(10).
    The test is not
    particularly onerous: it consists of two pages with thirteen
    7
    multiple-choice questions and two True/False questions. 1 The
    examinee must answer eleven questions correctly (a score of
    70%). He need pass the test only once, 
    id., and he
    can retake
    it as many times as he wants. See 24 DCMR § 2311.7–.8.
    The test is intended to ensure gun owners have a “basic level
    of knowledge” about the District’s firearms laws. Comm.
    Report 17. Those laws, in turn, promote the public safety. 
    Id. The plaintiffs
    contend, and my colleagues agree, that the
    District presented “no evidence” its knowledge test furthers
    its alleged interests. Appellants’ Br. 53–54; Maj. Op. 24. But
    the notion that test-taking promotes knowledge is obvious—
    ask any teacher, student or professional licensing board in the
    country. See Delaware v. Prouse, 
    440 U.S. 648
    , 658 (1979)
    (“States have a vital interest in ensuring that only those
    qualified to do so are permitted to operate motor vehicles . . .
    [and] are sufficiently familiar with the rules of the road
    . . . .”); Levitt v. Comm. for Pub. Educ. & Religious Liberty,
    
    413 U.S. 472
    , 480 (1973) (“a regular program of traditional
    internal testing designed to measure pupil achievement” plays
    an “obviously integral role . . . in the total teaching process”);
    Schware v. Bd. of Bar Exam., 
    353 U.S. 232
    , 239 (1957) (“A
    State can require high standards of qualification, such as . . .
    proficiency in its law, before it admits an applicant to the bar
    . . . .”). Several of the District’s experts testified to that effect.
    1
    The questions are not difficult. Consider, for example,
    Question 3:
    Firearms may be lawfully discharged on public space in the
    District of Columbia:
    (A)      Into the air on New Year’s Eve.
    (B)      At registered turkey hunts on Thanksgiving.
    (C)      After obtaining a special written permit from the
    Chief of Police authorizing the weapon to be
    discharged on public space.
    8
    See Lanier Decl. ¶¶ 23–24; Jones Decl. ¶ 23; Webster Decl.
    ¶ 35; Lanier Test. 2; Jones Report 10. Under intermediate
    scrutiny, the District does not need to cite empirical studies
    for the common-sense notion that mandatory testing promotes
    knowledge of, and obedience to, its laws. See Lorillard
    Tobacco Co. v. Reilly, 
    533 U.S. 525
    , 555 (2001) (“[W]e have
    permitted litigants . . . even[] in a case applying strict
    scrutiny, to justify restrictions based solely on history,
    consensus, and ‘simple common sense.’ ” (quoting Went For
    
    It, 515 U.S. at 628
    (emphasis added)); Nat’l Cable &
    Telecomms. Ass’n v. FCC, 
    555 F.3d 996
    , 1002 (D.C. Cir.
    2009) (we do not require “exhaustive evidence documenting
    the necessity of [a given law]” and we have “relied on [the
    legislature’s] reasonable, commonsense determination that
    [the law is] required”). See generally Nixon v. Shrink Mo.
    Gov’t PAC, 
    528 U.S. 377
    , 391 (2000) (“The quantum of
    empirical evidence needed to satisfy heightened judicial
    scrutiny of legislative judgments will vary up or down with
    the novelty and plausibility of the justification raised.”).
    The plaintiffs do not identify any alternative means by
    which the District can achieve its goals. Their implied
    alternative—no test at all—is plainly lacking. Given the
    uniqueness and complexity of the District’s firearms laws, it
    has an especially pressing need to educate its citizens about
    their contents. Under intermediate scrutiny, the District can
    “add[] a prophylaxis to the law,” even if it “focuses upon
    behavior already arguably proscribed by other laws.” Time
    
    Warner, 211 F.3d at 1320
    ; see also United States v. Mahin,
    
    668 F.3d 119
    , 127 (4th Cir. 2012) (“The Second Amendment
    does not disable Congress and the states from erecting
    preventative measures . . . .” (emphasis added)). Granted, in
    criminal cases, courts usually presume that individuals know
    the law. See McFadden v. United States, 
    135 S. Ct. 2298
    ,
    2304 (2015) (“[I]gnorance of the law is typically no defense
    9
    to criminal prosecution . . . .”). But this presumption is a legal
    fiction, not an accurate description of the world. See McBoyle
    v. United States, 
    283 U.S. 25
    , 27 (1931); see also JOHN
    SELDEN, TABLE-TALK 174 (Constable & Co. 1827)
    (“Ignorance of the law excuses no man; not that all men know
    the law, but because ‘tis an excuse every man will plead, and
    no man can tell how to confute him.” (emphasis added)). All
    too often, individuals do not know the law and legislatures do
    well to ensure they are informed before they can own and use
    a dangerous weapon.
    In sum, I believe the District’s knowledge test satisfies
    intermediate scrutiny. It ensures a gun owner has a basic
    understanding of the District’s firearms laws—laws that
    unquestionably promote the public safety.
    B. Presenting the Firearm
    The Metropolitan Police Department (MPD) can require
    a potential registrant to present his firearm for inspection.
    D.C. CODE § 7-2502.04(c).           The law has an obvious,
    straightforward purpose: verification. See Appellees’ Br. 47–
    48; Defs.’ Summ. J. Reply Br. 25 n.21. The MPD wants to
    conduct a physical inspection to “verify that the application
    information is correct and that the firearm has not been
    altered.” Appellees’ Br. 47–48; see 24 DCMR § 2313.8(c)
    (“The Director may require an applicant to return with the
    firearm if . . . the information relating to the weapon on the
    application [appears] incorrect, misleading, or incomplete.”).
    It also wants to ensure the firearm is in safe operating
    condition and does not belong to a prohibited class of
    weapons. See 24 DCMR § 2313.8(b) (“The Director may
    require an applicant to return with the firearm if . . . the
    firearm may be unregisterable, defective, or in a dangerous
    condition or state of disrepair.”).
    10
    The plaintiffs contend, and my colleagues agree, that
    physically inspecting a firearm is unnecessary because no one
    would both register a firearm and lie about its physical
    characteristics—they would simply decline to register it in the
    first place. See Maj. Op. 21. But the present-the-firearm
    requirement is not targeted at falsehoods only; the District is
    also worried about innocent mistakes. See 24 DCMR
    § 2313.8(c) (“The Director may require an applicant to return
    with the firearm if . . . the application [appears] incorrect . . .
    or incomplete.” (emphases added)). And many registrants
    will not be aware that their firearm is unsafe to operate or
    ineligible to be registered, see 
    id. § 2313.8(b),
    until they
    present it and allow the MPD to take a closer look.
    The plaintiffs further contend that the District’s interest
    in verification is outweighed by the burdens that presenting
    the firearm imposes on registrants. According to the
    plaintiffs, a person who presents his firearm to the MPD could
    be arrested, have his gun stolen or be mistaken for an
    assailant. These risks, in my mind, are quite overblown. For
    starters, it is not a crime to transport a firearm to the MPD for
    the purpose of registering it. See D.C. CODE §§ 22-4504.01;
    22-4504.02(a); 18 U.S.C. § 926a. Moreover, registrants are
    instructed to leave their firearm at home unless asked to
    present it, 24 DCMR § 2313.7, and must transport the firearm
    “in accordance with [section] 22-4504.02,” D.C. CODE § 7-
    2502.04(c)—i.e., unloaded, stored in a locked container,
    separate from any ammunition and inaccessible to the driver
    and any passenger, see 
    id. § 22-4504.02(b)–(c).
    These
    provisions minimize the risk of an accident. And any
    remaining risk of theft or misunderstanding is an inherent
    feature of owning a firearm—not a unique problem created by
    the District’s laws.
    11
    Accordingly, I believe the present-the-firearm
    requirement satisfies intermediate scrutiny. It imposes a
    slight burden on registrants and allows the District to verify
    that the firearm is described correctly, has not been altered, is
    safe to operate and is eligible for registration.
    C. Re-Registration
    The District’s registration certificates expire every three
    years. 
    Id. § 7-2502.07a(a).
    Thus, a gun owner who wants to
    maintain his registration must periodically renew it. 
    Id. Renewal is
    “simple” by design. Comm. Report 10. The
    registrant fills out a two-page form online, by mail or in
    person. D.C. CODE § 7-2502.07a(c). The form includes a
    questionnaire to determine whether the registrant remains
    qualified to possess a firearm and requests his current address
    and an attestation that he continues to possesses the firearm.
    See Firearms Registration Renewal Application, METRO.
    POLICE DEP’T, available at http://mpdc.dc.gov/sites/default/
    files/dc/sites/mpdc/publication/attachments/Firearms%20Regi
    stration%20Renewal%20Form%2012.18.13.pdf (last visited
    September 17, 2015). 2 The District reminds a registrant to
    renew his certificate ninety days in advance, D.C. CODE § 7-
    2502.07a(e)(1), and gives him a ninety-day grace period after
    2
    To renew the certificate for a firearm registered before
    January 1, 2011, a registrant must also appear in person and be
    fingerprinted. See 24 DCMR § 2326.2. This process is a one-time
    requirement and does not apply to subsequent renewals. See
    Firearms Registration Renewal: Complete Renewal Procedures,
    METRO. POLICE DEP’T, available at http://mpdc.dc.gov
    /page/firearms-registration-renewal-complete-renewal-procedures
    (last visited September 17, 2015) (“Subsequent registration
    renewals will be done online or by mail.”). It is constitutional for
    the same reasons that the re-registration, fingerprinting and in-
    person appearance requirements are constitutional.
    12
    the renewal period expires, see 24 DCMR § 2326.4. Re-
    registration serves several purposes. It promotes public safety
    by allowing the District to monitor whether a gun owner has
    fallen into a class of people who cannot legally possess a
    firearm (e.g., felons, the mentally ill, subjects of protective
    orders). See Comm. Report 4, 11–12; Jones Decl. ¶ 23;
    Lanier Decl. ¶ 21; Vince Decl. ¶ 22; Webster Decl. ¶ 30. And
    it keeps the District’s firearms registry up to date. See Comm.
    Report 4, 10. The MPD needs updated information, including
    the registrant’s most recent address, so that it knows where to
    retrieve the firearm if the owner becomes disqualified to
    possess it. See Lanier Decl. ¶ 21; Webster Decl. ¶ 30; see
    also Appellees’ Br. 48 (“The District . . . has a population that
    is significantly more transient than other states.”). Moreover,
    re-registration helps combat the loss and illegal transfer of
    firearms by requiring a registrant to account for his weapons
    on a regular basis and by providing MPD with “up-to-date
    information about the firearm’s last legal whereabouts.”
    Comm. Report 11; see also 
    id. at 8,
    10; Webster Decl. ¶ 30.
    The plaintiffs argue that the District could achieve each
    of these goals with less burdensome alternatives. As for
    ensuring that a registrant does not fall into a disqualified
    class, the plaintiffs note that the District is free to run
    background checks whenever it pleases. Yet background
    checks are less efficient and effective than a universal re-
    registration requirement, the latter ensuring that everyone
    remains eligible to own a firearm. See Jones Decl. ¶ 24 (re-
    registration provides “mandatory accountability to . . . public
    safety officials”); 
    id. at ¶
    23 (re-registration “compels a
    systemic review of all legally registered firearms and
    registrants”). “Of course, administrative convenience and
    economic cost-saving are not, by themselves, conclusive
    justifications for burdening a constitutional right under
    intermediate scrutiny. However, such considerations are
    13
    relevant to [the Second Amendment analysis].” 
    Bonidy, 790 F.3d at 1127
    (emphasis added). At bottom, the District needs
    to show that re-registration does not burden “substantially
    more [rights] than is necessary,” not that it is the “least
    intrusive means” of keeping tabs on gun owners. McCullen v.
    Coakley, 
    134 S. Ct. 2518
    , 2535 (2014) (quoting 
    Ward, 491 U.S. at 798
    –99). Assuming they could reveal all the reasons
    someone might become disqualified to possess a firearm (a
    dubious proposition, see generally D.C. CODE § 7-
    2502.03(a)), I fail to see how dragnet background checks are
    “substantially” less burdensome than filling out a two-page
    form every three years. 
    McCullen, 134 S. Ct. at 2535
    .
    Moreover, background checks plainly do not further the
    District’s interests in updating its firearms registry and
    promoting accountability of gun owners.
    As for the latter interests, the plaintiffs point out that a
    gun owner is already required to notify the District if he
    changes his address or loses his firearm. See D.C. CODE § 7-
    2502.08(a). But the District tried to rely on registrant
    notification for several years and the experiment failed.
    According to the Committee Report, “[relying on notification
    alone] has not been effective. Thousands of registrants have
    moved, died, disposed of their guns (or perhaps lost them) and
    have not notified MPD. . . . [M]any registrants cannot be
    located.” Comm. Report 10; see also Jones Decl. ¶ 24.
    Instead of continuing to depend on registrant-initiated
    notification, the District’s re-registration requirement provides
    “mandatory accountability” by forcing a registrant to update
    his information under threat of cancellation. Jones Decl. ¶ 24;
    see also Vince Decl. ¶ 22; Webster Decl. ¶ 30 (re-registration
    “is analogous to the widely-accepted Federal requirement that
    licensed gun dealers be audited periodically to make sure that
    they can account for their firearms”). This is a permissible
    alternative under intermediate scrutiny. See Nat’l Cable &
    14
    Telecomm’ns 
    Ass’n, 555 F.3d at 1002
    (affirming opt-in
    scheme because “opt-out is only marginally less intrusive than
    opt-in” and agency “carefully considered the differences
    between the[] two” and made “reasonable, commonsense
    determination” (citation omitted)). “[T]he Constitution does
    not require that the [District] choose ineffectual means.”
    Rosario v. Rockefeller, 
    410 U.S. 752
    , 762 n.10 (1973).
    My colleagues do not believe the re-registration
    requirement deters the loss or illegal transfer of firearms
    because it does not require a registrant to produce the gun; it
    “requires only that [he] affirm that he still has [it].” Maj. Op.
    23. In other words, my colleagues believe registrants will not
    be truthful on their re-registration forms. The plaintiffs do not
    make this argument in their briefs, however, so we need not—
    indeed, should not—consider it. See 
    Schrader, 704 F.3d at 991
    –92. Nor is the argument persuasive. A re-registrant must
    attest, under penalty of perjury, that he still possesses the
    firearm. See Firearms Registration Renewal 
    Application, supra, at 11
    . In my view, the District reasonably assumes that
    most re-registrants will tell the truth. Cf. Rehberg v. Paulk,
    
    132 S. Ct. 1497
    , 1505 (2012) (threat of perjury prosecution
    adequately deters false testimony).
    In short, I believe the District’s re-registration
    requirement passes constitutional muster. It imposes only
    minimal burdens on Second Amendment rights and
    simultaneously satisfies the District’s interests in preventing
    disqualified people from owning firearms, keeping the
    firearms registry up-to-date and deterring the loss and illegal
    transfer of firearms.
    D. One Pistol Per Thirty Days
    The District prohibits a registrant from registering more
    than one pistol in the same thirty-day period. D.C. CODE § 7-
    15
    2502.03(e); 24 DCMR § 2305.3; see also D.C. CODE § 7-
    2501.01(12) (defining “pistol” as “any firearm originally
    designed to be fired by use of a single hand or with a barrel
    less than 12 inches in length”). This limitation does not apply
    to an individual who relocates to the District and wants to
    register pistols he lawfully owned in another jurisdiction for
    at least six months. D.C. CODE § 7-2502.03(e); 24 DCMR
    § 2305.4. 3 The parties agree that the purpose behind the one-
    pistol-per-thirty-days rule is to stem the illegal trafficking of
    handguns. See Comm. Report 10, 14–15.
    The plaintiffs argue, however, that the one-pistol-per-
    month limitation does nothing to further this goal. No one,
    they point out, would bring pistols into the District, register
    them and then traffic them. The person would simply never
    register the pistols at all. But the plaintiffs focus on the
    wrong side of the equation. The one-pistol-per-thirty-days
    limitation is directed at the supply side, rather than the
    demand side, of illegal handgun trafficking. As stated in the
    Committee Report:
    The law burdens gun traffickers and the straw
    purchasers they hire to supply them with guns, and it
    makes it more difficult for the rare dirty gun dealer
    who is willing to look the other way when a single
    individual walks in to his store asking to buy five or
    10 or even 20 or more inexpensive handguns to be
    sold on the street.
    Comm. Report 16 (quoting Douglas Weil, A Law that Gun-
    Rights Advocates Should Be Fighting to Keep, WASH. POST
    3
    And the one-pistol-per-thirty-days limitation applies to the
    initial registration only; an individual can simultaneously re-
    register as many pistols as he wants. See 24 DCMR § 2305.3.

    /opinions/a-law-that-gun-rights-advocates-should-be-fighting-
    to-keep/2012/02/16/gIQAvcASKR_story.html); see also
    Jones Decl. ¶ 18; Lanier Decl. ¶ 29; Vince Decl. ¶ 17. In
    other words, the one-pistol-per-thirty-days limitation deters
    dealers from selling more than one handgun at a time because
    they know multiple handguns cannot be registered and, thus,
    cannot be possessed or used for a lawful purpose. The
    Committee Report points to Virginia as an example of a
    jurisdiction that, after enacting a similar law, successfully
    reduced illegal handgun trafficking. See Comm. Report 15–
    16; see also Jones Decl. ¶ 19. True, notwithstanding the one-
    pistol-per-thirty-days limitation, a firearms trafficker could
    acquire handguns from another jurisdiction and transport
    them into the District. See Maj. Op. 27. But the law
    nonetheless deters the rapid acquisition of multiple firearms
    within the District. See Comm. Report 16 (“Since other states
    permit multiple gun sales—including, now, Virginia—our
    District law remains important. Indeed, the other states
    should follow, so as to erect a wide web to frustrate the
    traffickers.”) The District need not—indeed, cannot—solve
    problems created by the relatively lax firearms laws in other
    jurisdictions. Cf. Williams-Yulee v. Fla. Bar, 
    135 S. Ct. 1656
    ,
    1668 (2015) (even under strict scrutiny, “[a] State need not
    address all aspects of a problem in one fell swoop;
    policymakers may focus on their most pressing concerns”). 4

    My colleagues point out that the sources cited in the
    Committee Report discuss limitations on the purchase, not the
    registration, of handguns. See Maj. Op. 27. The plaintiffs,
    however, do not make this argument and I do not believe we should
    do so on their behalf. See 
    Schrader, 704 F.3d at 991
    –92. Even if
    we did, I think any distinction between purchase and registration is
    immaterial. Because the District prohibits the possession of
    17
    Given the record evidence supporting it, the one-pistol-
    per-thirty-days limitation is constitutional—a conclusion that
    is bolstered by the fact that it imposes very little burden on
    Second Amendment rights. The plaintiffs contend—and my
    colleagues suggest, see Maj. Op. 27–28—that an individual
    has as much constitutional right to a second pistol as he does
    the first. They note that the Second Amendment discusses the
    right to keep and bear “Arms,” plural. See 
    id. But I
    doubt
    their textual point has much force: the Second Amendment
    also uses the word “people,” plural, so the “s” on “Arms” is
    grammatically necessary. And Heller does not support their
    position either. The “core” of the Second Amendment is the
    right to use a firearm for self-defense in the home, 
    Heller, 554 U.S. at 630
    —a right that is vindicated with one handgun. The
    plaintiffs’ position has no stopping point: it would authorize
    everyone to possess his own Rambo-style armory. Cf. 
    id. at 627
    (noting that Second Amendment does not protect right to
    form “effective” militia (emphasis added)). In any event, we
    need not decide whether the Second Amendment protects the
    right to a second firearm as much as the first firearm because,
    even assuming it does, the one-pistol-per-month limitation is
    only a small (and temporary) limit on Second Amendment
    rights. It imposes a thirty-day waiting period on the right to
    acquire a second pistol—an acceptable burden, given the
    availability of the first pistol, the availability of other firearms
    and the deadly costs of illegal handgun trafficking. Cf.
    
    Rosario, 410 U.S. at 760
    –62 (requiring party registration
    eight months in advance of presidential primary is
    constitutional means of preventing one party’s voters from
    designating themselves as another party’s voters).
    unregistered firearms, D.C. CODE § 7-2502.01(a), a limitation on
    registration is the functional equivalent of a limitation on purchases.
    18
    In conclusion, I agree with my colleagues’ decision to
    uphold the District’s long-gun registration, registration fee,
    in-person appearance, photographing, fingerprinting and
    training requirements. Those parts of the majority opinion
    display proper deference to the District in its ongoing efforts
    to formulate a workable firearms policy for our Nation’s
    capital. I believe my colleagues too readily abandon this
    approach, however, with respect to the knowledge test,
    present-the-firearm, re-registration and one-pistol-per-thirty-
    days requirements. Accordingly, I respectfully dissent in part.
