    AGEE, Circuit Judge:
    Respondent-Appellant                Thomas        Heyer    (“Heyer”)        appeals      the
    district      court’s            order    of       civil    commitment          following        an
    evidentiary hearing pursuant to 18 U.S.C. § 4248.                                     On appeal,
    Heyer—who     is          deaf    and    communicates           through        sign     language—
    contends that the district court abused its discretion in only
    allowing    simultaneous            interpretation,             rather    than        consecutive
    interpretation,            during       the    evidentiary           hearing.         Heyer    also
    contends that the district court clearly erred in finding him to
    be a “sexually dangerous person” under § 4248, and further erred
    in rejecting his equal protection and due process claims.                                       For
    the reasons that follow, we affirm the judgment of the district
    court.
    I.
    A.
    The Adam Walsh Child Protection and Safety Act of 2006 (the
    “Act”),     18        U.S.C.       §§ 4247–4248,           provides        for        the     civil
    commitment           of     sexually          dangerous         persons        following        the
    expiration of their federal prison sentences.                                   See 18 U.S.C.
    § 4248(a).           A     “sexually      dangerous         person”       is    one     “who    has
    engaged or attempted to engage in sexually violent conduct or
    child molestation and who is sexually dangerous to others.”                                    See
    18   U.S.C.      §    4247(a)(5).              A   person       is    considered        “sexually
    2
    dangerous    to    others”   if     “the    person      suffers    from    a   serious
    mental illness, abnormality, or disorder as a result of which he
    would     have    serious    difficulty         in    refraining    from       sexually
    violent    conduct     or   child    molestation         if   released.”        
    Id. at §
    4247(a)(6).
    The Attorney General, his designee, or the Director of the
    Federal     Bureau    of    Prisons     (“BOP”)        may    initiate     a   §   4248
    commitment proceeding in the district court for the district in
    which the person is confined by filing a certification that the
    person is sexually dangerous within the meaning of the Act.                           See
    18 U.S.C. § 4248(a).             Such a filing automatically stays the
    release of the person from custody pending a hearing before the
    district court.         See 
    id. “If, after
    the hearing, the court
    finds by clear and convincing evidence that the person is a
    sexually dangerous person, the court shall commit the person to
    the custody of the Attorney General.”                  
    Id. § 4248(d).
    B.
    On December 18, 2008, the Government initiated this action
    by filing a certificate pursuant to 18 U.S.C. § 4248(a) in the
    United States District Court for the Eastern District of North
    Carolina seeking to have Heyer civilly committed as a “sexually
    dangerous person” under the Act.                     The certificate stated that
    mental    health     personnel    for   the      BOP    had   examined     Heyer      and
    3
    issued     a    preliminary       determination      that     he     is    “sexually
    dangerous” within the meaning of the Act.                         See 18 U.S.C. §
    4248(a) (“In relation to a person who is in the custody of the
    [BOP], . . . the Attorney General or any individual authorized
    by the Attorney General or the Director of the [BOP] may certify
    that the person is a sexually dangerous person, and transmit the
    certificate to the clerk of the court for the district in which
    the person is confined.”).
    Pursuant         to   18   U.S.C.    §   4247(d),      the    district    court
    conducted an evidentiary hearing on May 30 and 31, 2012. 1                          Dr.
    Jeffrey Davis (“Dr. Davis”) and Dr. Heather Ross (“Dr. Ross”),
    forensic psychologists, provided forensic reports and testified
    on behalf of the Government that Heyer met the criteria for
    civil commitment.          Dr. Diane Lytton (“Dr. Lytton”), a forensic
    psychologist, provided a forensic report and testified on behalf
    of Heyer that he did not meet the criteria for commitment.                           In
    addition,       Dr.    Jean     Andrews   (“Dr.    Andrews”),       an    expert    in
    deafness       and    psychosocial    issues      related    to    deafness,       also
    provided a report and testified on behalf of Heyer.
    1
    We note that the four-year delay between the date the
    Government filed the § 4248 certificate on December 18, 2008, to
    the date of the hearing on May 30 and 31, 2012, is primarily
    attributable to the stay imposed in relation to United States v.
    Comstock, 
    560 U.S. 126
    (2010); see also United States v.
    Comstock, 
    627 F.3d 513
    (4th Cir. 2010); United States v.
    Comstock, 
    551 F.3d 274
    (4th Cir. 2009).
    4
    At the hearing, Heyer initially moved the court to provide
    him    with    consecutive,         rather       than   simultaneous,         interpreting.
    The district court denied Heyer’s request, stating, “Well, it’s
    a civil case.         The answer is no.               We are not going to make this
    into a marathon.”           (J.A. 87.)
    Based on the evidence presented, the district court adopted
    the following undisputed findings of fact.                               Heyer is deaf and
    communicates through American Sign Language (“ASL”).                               Throughout
    his youth, Heyer was assaulted and molested numerous times.                                    In
    1989,    at    age    twenty-two,       Heyer         was     convicted      of    terroristic
    threats after getting into an argument with a man who accused
    him of molesting his eight-year-old son.                            Around the same time,
    Heyer was also convicted of burglary and armed robbery.
    In 1993, Heyer molested a ten-year-old boy, then tied the
    boy up and placed him in a hole.                      He was convicted of kidnapping
    and sentenced to ten years in prison.                               In the several years
    following Heyer’s release from prison, he was convicted of a
    series        of     misdemeanors,           including            offenses        for     public
    intoxication,             driving      under            the        influence,           reckless
    endangerment, vandalism, and passing a bad check.
    Around      2002,    Heyer     was     found         to    have   approximately         180
    images of child pornography in his possession.                             He subsequently
    pled    guilty       to   possession        of       child       pornography.           Upon   his
    release from prison for the child pornography conviction, he
    5
    began sex offender treatment while on supervised release.                                     His
    supervised release, however, was revoked in 2007 when he showed
    up at a treatment session under the influence of alcohol.
    Heyer    also      admitted      to    the      following       additional           facts
    during a deposition which was admitted into the record.                                     Heyer
    admitted that while he was on probation, he looked at “a lot of
    different       websites        that     were      triple-x,”        (J.A.        432),       and
    masturbated to those images (J.A. 432–33).                          The pictures Heyer
    viewed     included        adults       and       children     together           in      sexual
    situations;         he   also   admitted        that    he    showed       some     of      these
    pictures       to    [redacted],       a     young     teenage       boy     whom      he     had
    befriended.         Heyer further admitted to having engaged in sexual
    activity,       including       mutual       masturbation        and       oral     sex      with
    [redacted] while [redacted] was a young teenager, and that such
    sexual activity occurred over a period of approximately one-and-
    a-half     years.         Although         Heyer     knew    that      having       sex      with
    [redacted] was wrong, he continued the activity because “I liked
    it and he was willing.”                (J.A. 450.)           He also told [redacted]
    that he liked having sex with other children.
    In addition, Heyer admitted to having had sexual contact
    with   between       eighteen     and       twenty-five       boys     after      he      turned
    eighteen years old.             Among other child victims Heyer molested
    6
    was     his    nephew,        whom   he    molested        when   the      nephew      was
    approximately six years old. 2
    Heyer also admitted to using both marijuana and cocaine
    while he was on probation during 2007 and that he went to sex
    offender      treatment       “drunk”     during      this    time.        (J.A.    456.)
    According to Heyer, he did not consider himself to be “drunk”
    previously when he was arrested for driving under the influence
    (despite blowing a 0.17 on the blood alcohol test) because he
    was “able to walk straight.”              (J.A. 442.)
    According to Dr. Lytton, Heyer’s own expert examiner, Heyer
    admitted to the following additional facts during his interview
    with her.          He “described his adolescent years as plagued by
    fighting and being the victim of sexual aggression.”                        (J.A. 627–
    28.)       In addition, Heyer admitted that his “typical pattern as a
    young      adult   was   to    spend    his       entire   paycheck   on    an     alcohol
    binge, and live meagerly until the next payday.”                      (J.A. 627.)
    Heyer further admitted that he “often exposed himself to
    strangers in efforts to gauge their sexual interest in him,” and
    that he would “attempt to view other people’s private parts when
    in bathrooms or showers.”                 (J.A. 628.)        He also admitted “to
    some arousal to pre-pubescent boys, around age eight,” and “to
    2
    It is unclear whether this happened on more than one
    occasion, since Heyer indicated that the molestation “stopped”
    when his nephew was six years old. (J.A. 489.)
    7
    fondling a number of young boys, incidents for which he was not
    investigated         or    charged.”       (J.A.       628.)      Lastly,       during   the
    commission of the crime in 1993 where he kidnapped and molested
    a boy, then tied him up and left him in a hole, Heyer admitted
    that    he    “buried       the    boy   to     avoid       detection”    and     then   was
    “deceptive with police, and did not provide information that
    would have led to the discovery of the boy.”                         (J.A. 629.)
    Both of the experts that testified for the Government, Dr.
    Ross and Dr. Davis, opined that Heyer suffered from pedophilia,
    as     well     as        other     mental          disorders—including         antisocial
    personality disorder and substance abuse problems—and would have
    serious       difficulty          refraining         from    future     acts      of   child
    molestation if released.                 Dr. Lytton, who testified on these
    issues for Heyer, opined that she did not believe he currently
    suffers       from        either    pedophilia         or     antisocial       personality
    disorder.        She       acknowledged,      however,        that     “Heyer’s    criminal
    history includes past behaviors that suggest he may have met
    such criteria [for pedophilia] at that time.”                           (J.A. 631.)      Dr.
    Lytton further opined that “[i]t would be difficult to argue
    that    Mr.    Heyer        did    not   meet       the     criteria    [for    antisocial
    personality disorder] in the past.”                    (J.A. 631.)
    On July 9, 2012, the district court issued its Findings of
    Fact and Conclusions of Law pursuant to Federal Rule of Civil
    Procedure 52(a)(1), concluding that the Government had proven by
    8
    clear        and   convincing        evidence         that   Heyer     was    a   “sexually
    dangerous person” within the meaning of the Act.                             Specifically,
    the district court found that Heyer currently suffers from the
    serious mental illness of pedophilia, and that Dr. Ross and Dr.
    Davis had provided a more convincing analysis than Dr. Lytton.
    The court concluded that the Government had “met its burden to
    demonstrate          by    clear    and   convincing         evidence    that     Mr.    Heyer
    suffers from a serious mental illness, abnormality, or disorder
    as a result of which he would have serious difficulty refraining
    from sexually violent conduct or child molestation if released.”
    (J.A. 521.)           The district court accordingly committed Heyer to
    the   custody         of    the    Attorney      General      pursuant       to   18    U.S.C.
    § 4248.
    Heyer timely appealed, and we have jurisdiction under 28
    U.S.C. § 1291.
    II.
    On    appeal,       Heyer    contends         that   the   district       court   (1)
    abused         its        discretion       in         allowing       only     simultaneous
    interpretation, rather than consecutive interpretation, during
    the evidentiary hearing; (2) clearly erred in finding him to be
    a “sexually dangerous person” under 18 U.S.C. § 4248; and (3)
    erred in rejecting his equal protection and due process claims.
    We address each argument in turn.
    9
    A.
    Heyer first contends that the district court abused its
    discretion in allowing only simultaneous interpretation, rather
    than consecutive interpretation, during the evidentiary hearing.
    Heyer   asserts     his    claim   under     the    authority     of   the   Court
    Interpreters Act (“CIA”), 28 U.S.C. §§ 1827–28.                   We review the
    district court’s final determination on the appointment and use
    of   interpreters    for   an   abuse   of    discretion,    as    the   district
    court “is in the best position to evaluate the need for and the
    performance of interpreters.”              United States v. Sandoval, 
    347 F.3d 627
    , 632 (7th Cir. 2003); accord United States v. Camejo,
    
    333 F.3d 669
    , 673 (6th Cir. 2003); United States v. Urena, 
    27 F.3d 1487
    , 1492 (10th Cir. 1994).                  To the extent that Heyer
    claims a hearing on this issue was required, such a claim is
    reviewed for plain error since he did not request such a hearing
    in the district court.          United States v. Olano, 
    507 U.S. 725
    ,
    731–32 (1993); United States v. Hastings, 
    134 F.3d 235
    , 239 (4th
    Cir. 1998).
    Initially, we note that the CIA requires only simultaneous
    interpretation      for     non-witnesses,         unless   the    court     rules
    otherwise:
    The interpretation provided by certified or
    otherwise qualified interpreters pursuant to
    this section shall be in the simultaneous
    mode for any party to a judicial proceeding
    instituted by the United States and in the
    10
    consecutive mode for witnesses, except that
    the presiding judicial officer, sua sponte
    or on the motion of a party, may authorize a
    simultaneous, or consecutive interpretation
    when such officer determines after a hearing
    on the record that such interpretation will
    aid in the efficient administration of
    justice.
    28 U.S.C. § 1827(k) (emphasis added).                    The statute explicitly
    provides that interpretation “shall be in the simultaneous mode”
    for non-witnesses, unless the district court rules otherwise. 3
    
    Id. The effective
    presumption of simultaneous interpretation
    will change only if the district court determines that it “will
    aid in the efficient administration of justice.”                 
    Id. In this
    case, the sum and substance of the district court’s
    ruling was that consecutive interpretation would not “aid in the
    efficient administration of justice,” 
    id., because consecutive
    interpretation     of    the     entire        proceeding    would   have   unduly
    delayed and enlarged the evidentiary hearing.                  When the district
    court       inquired     as      to   why        Heyer      wanted     consecutive
    interpretation,        Heyer’s    attorney        responded,    “[b]ecause     the
    potential problem is that we could be way down the road before
    we realize that Mr. Heyer doesn’t understand something.”                     (J.A.
    3
    If Heyer had testified, he would have been entitled to
    consecutive interpretation during his testimony, unless the
    district court ruled otherwise. See 28 U.S.C. § 1827(k). Heyer
    did not testify at the evidentiary hearing and makes no claim to
    consecutive interpretation on the witness portion of the
    statute.
    11
    87.)       That single response was the complete rationale proffered
    for    departure      from    the    statutory       presumption    of       simultaneous
    interpretation with no tender by Heyer, then or now, of what a
    “potential problem” might be.                 (J.A. 87.)      Moreover, at no point
    during the two-day hearing did Heyer or his attorney indicate to
    the    district        court     that     Heyer       did     not   understand         the
    proceedings.          Thus,     there    was   never    any   indication        that   the
    speculative “potential problem,” (J.A. 87), had become an actual
    problem.
    Moreover, the district court made a number of substantial
    accommodations to help Heyer understand the proceedings. 4                             The
    court provided both qualified and certified legal interpreters,
    as well as certified deaf interpreters, so that a total of four
    interpreters         were    present     at    all    times    during    the     two-day
    hearing.      An interpreter was also permitted to sit with Heyer at
    counsel table throughout the proceeding.                       The district court
    also       allowed     Heyer,       on   several       occasions,       to     stop    the
    proceedings if he did not understand what was going on.
    Further, contrary to Heyer’s assertion, the district court
    was not required to hold a hearing on whether or not to grant
    4
    Prior to trial, Dr. Andrews, Heyer’s linguistic expert,
    made six recommendations to the district court concerning
    accommodations that would help Heyer understand the proceedings.
    The only accommodation that the district court did not grant in
    toto was the suggestion of consecutive interpretation throughout
    the hearing.
    12
    the request for consecutive interpretation.                         The CIA provides
    that   “the     presiding    judicial      officer,    sua      sponte     or   on   the
    motion     of    a     party,      may    authorize        .    .     .    consecutive
    interpretation when such officer determines after a hearing on
    the record that such interpretation will aid in the efficient
    administration        of   justice.”         28   U.S.C.       § 1827(k)    (emphasis
    added).       Heyer made no request for a hearing in the district
    court, and did not object to the district court’s denial of the
    request    for       consecutive     interpretation.             Accordingly,        the
    district court’s decision to not hold a hearing sua sponte is
    reviewed    only     for   plain    error.        
    Olano, 507 U.S. at 731
    –32;
    
    Hastings, 134 F.3d at 239
    .               To succeed, Heyer must demonstrate
    that an error occurred, that the error was plain, and that the
    error affected his substantial rights.                 See 
    Olano, 507 U.S. at 732
    ; 
    Hastings, 134 F.3d at 239
    .                Even if Heyer can satisfy these
    requirements, correction of the error remains in the Court’s
    sound discretion, which it “‘should not exercise . . . unless
    the error seriously affects the fairness, integrity, or public
    reputation of judicial proceedings.’”                
    Hastings, 134 F.3d at 239
    (quoting 
    Olano, 507 U.S. at 732
    ) (internal quotation marks and
    alteration omitted).
    Heyer is unable to show any error here, much less plain
    error.     It is unclear what evidence, if any, Heyer would have
    submitted during a hearing on the matter that had not already
    13
    been presented through the report of Dr. Andrews, which had been
    filed with the district court more than five months prior to the
    hearing.     In   his   briefing,       Heyer    does    not   indicate    any
    additional   information   that    he    would    have   submitted   to    the
    district court on this issue.       Further, Heyer cites no case law
    in which any court has held that the refusal to hold a hearing
    on whether to grant such a motion was an abuse of discretion,
    much less plain error.        Moreover, there is no evidence that
    Heyer suffered any prejudice from the district court’s failure
    to hold a hearing on this issue.
    Lastly, Heyer contends that the district court based its
    refusal to grant consecutive interpretation on a “mistake of
    law,” which he claims is a per se abuse of discretion.                    Heyer
    bases his argument on a single statement by the district court
    that this is a civil matter, rather than a criminal proceeding:
    THE COURT: Why     do    you    want    [consecutive
    interpretation]?
    MS. GRAVES [Counsel for Heyer]: Because the
    potential problem is that we could be way
    down the road before we realize that Mr.
    Heyer doesn’t understand something.
    THE COURT: Well, it’s a civil case.     The
    answer is no. We are not going to make this
    into a marathon.
    MS. GRAVES [Counsel for Heyer]: Thank you,
    Your Honor.
    14
    (J.A. 87.)    According to Heyer, this statement by the district
    court shows that it did not understand that the CIA applies to
    civil and criminal cases without distinction.            We disagree.     The
    district court merely indicated that, in the exercise of its
    discretion under § 1827(k), it was less likely to grant such a
    request in a civil case than in a criminal case.             There was no
    suggestion   by   the   district   court   or   the   Government   that   the
    court was without authority to grant the motion; only that it
    chose not do so in this civil commitment case. 5
    Accordingly, we affirm the judgment of the district court
    in denying Heyer’s request for consecutive interpretation.
    5
    Heyer also asserts that the district court’s refusal to
    grant consecutive interpretation violated his due process
    rights. As with his statutory argument under the CIA, however,
    Heyer never objected to the district court’s denial of
    consecutive interpretation below and raises this argument for
    the first time on appeal. Moreover, as we have already pointed
    out, the district court fully complied with 18 U.S.C. § 1827 and
    made substantial accommodations to help Heyer understand the
    proceedings. And, as also noted above, Heyer made no showing at
    trial, or on appeal, of any actual prejudice.      Heyer further
    acknowledges that “his due process rights as a civil commitment
    respondent are not as extensive as those afforded a criminal
    defendant.” (Opening Br. 29 n.8.) We find Heyer’s due process
    claim to be meritless.
    15
    B.
    Heyer next contends that the district court clearly erred
    in finding him to be a “sexually dangerous person” under 18
    U.S.C. § 4248.
    To obtain a commitment order against Heyer, the Government
    was    required   to   establish    three      distinct    facts   by    clear   and
    convincing evidence: that Heyer (1) “has engaged or attempted to
    engage in sexually violent conduct or child molestation” in the
    past,    18   U.S.C.   §   4247(a)(5);     (2)    currently     “suffers    from   a
    serious mental illness, abnormality, or disorder”; and (3) as a
    result of the illness, abnormality, or disorder, “would have
    serious difficulty in refraining from sexually violent conduct
    or child molestation if released,” 18 U.S.C. § 4247(a)(6); see
    also United States v. Hall, 
    664 F.3d 456
    , 461 (4th Cir. 2012).
    “[C]lear and convincing has been defined as evidence of such
    weight that it produces in the mind of the trier of fact a firm
    belief or conviction, without hesitancy, as to the truth of the
    allegations sought to be established, and, as well, as evidence
    that proves the facts at issue to be highly probable.”                      Jiminez
    v.    DaimlerChrysler      Corp.,   
    269 F.3d 439
    ,    450   (4th    Cir.   2001)
    (internal quotation marks, citations, and alterations omitted).
    On appeal, we review the district court’s factual findings
    for clear error and its legal conclusions de novo.                      See Fed. R.
    Civ. P. 52(a)(6); 
    Hall, 664 F.3d at 462
    .                  A finding is “clearly
    16
    erroneous” only if “the reviewing court on the entire evidence
    is left with the definite and firm conviction that a mistake has
    been committed.”     
    Hall, 664 F.3d at 462
    .           “This standard plainly
    does not entitle a reviewing court to reverse the finding of the
    trier of fact simply because it is convinced that it would have
    decided the case differently.”            Anderson v. City of Bessemer,
    N.C.,   
    470 U.S. 564
    ,   573   (1985).       “If   the    district   court’s
    account of the evidence is plausible in light of the record
    viewed in its entirety, the court of appeals may not reverse it
    even though convinced that had it been sitting as the trier of
    fact, it would have weighed the evidence differently.”                  
    Id. at 573–74.
    “When findings are based on determinations regarding the
    credibility of witnesses,” we give “even greater deference to
    the   trial   court’s   findings.”        
    Id. at 575.
        In   particular,
    “[e]valuating the credibility of experts and the value of their
    opinions is a function best committed to the district courts,
    and one to which appellate courts must defer,” and the Court
    “should be especially reluctant to set aside a finding based on
    the trial court’s evaluation of conflicting expert testimony.”
    Hendricks v. Cent. Reserve Life Ins. Co., 
    39 F.3d 507
    , 513 (4th
    Cir. 1994).
    We conclude that the district court did not clearly err in
    finding Heyer to be a “sexually dangerous person” within the
    17
    meaning of the Act because a review of the record demonstrates
    that the court properly considered all of the relevant evidence—
    including Heyer’s deafness and linguistic difficulties—to reach
    the appropriate decision.
    There is no dispute that Heyer engaged in past acts of
    child molestation, as evidenced by his prior convictions.                       Thus,
    the     district    court       properly       found     that    the     Government
    established the first element of sexual dangerousness by clear
    and convincing evidence.           See 18 U.S.C. § 4247(a)(5).             The crux
    of this issue, therefore, is whether the district court clearly
    erred    in   finding    that    the    Government     proved,     by    clear    and
    convincing     evidence,    that       Heyer   suffers    from    pedophilia,      “a
    serious mental illness, abnormality, or disorder,” as a result
    of which he “would have serious difficulty in refraining from
    sexually violent conduct or child molestation if released” from
    custody.      18 U.S.C. § 4247(a)(6).           Specifically, Heyer contends
    that    the    district     court       did     not    adequately        take    into
    consideration      his    deafness       and    linguistic       difficulties      in
    reaching its decision about whether or not he is a “sexually
    dangerous person” within the meaning of the Act.                        A review of
    the district court’s order, however, belies Heyer’s assertion.
    The district court clearly considered Heyer’s deafness and
    linguistic difficulties at length in reaching its Findings of
    Fact and Conclusions of Law.
    18
    Mr.   Heyer    was    born    prelingually   and
    profoundly deaf.       Because of Mr. Heyer’s
    unique circumstances and his severe deficits
    in linguistic functioning, Dr. Jean Frances
    Andrews, Director of Graduate Programs in
    Deaf    Education     at    Lamar    University,
    testified    in    regard    to    Mr.   Heyer’s
    linguistic competence.      Dr. Andrews opined
    in her report that Mr. Heyer’s reading level
    was at grade level 2.8 and that he lacks the
    advanced ASL skills required for interaction
    beyond social settings.       The Court credits
    Dr. Andrews’ testimony that Mr. Heyer has
    severe deficits in linguistic functioning.
    For that reason, the Court does not rely in
    its analysis on Mr. Heyer’s comprehension of
    the book Slave Sons, depicting sadistic
    sexual acts between a father and son, as Dr.
    Andrews testified that the book was written
    at grade level 7.8 and was well beyond Mr.
    Heyer’s understanding.
    (J.A. 525–26 (internal citations omitted).)      The court went on:
    The Court has also taken into account the
    fact   that  Mr.   Heyer’s  “statements”   in
    clinical     interviews      are     actually
    translations provided by interpreters and
    that some of the testifying psychologists
    [Dr. Ross and Dr. Davis] have not had
    experience in evaluating deaf individuals.
    Despite these qualifiers, the Court remains
    convinced that Mr. Heyer currently suffers
    from pedophilia, and that he would have
    serious   difficulty   in   refraining   from
    sexually    violent    conduct    or    child
    molestation if released.
    (J.A. 526 (internal citations omitted).)         These statements by
    the district court indicate that it properly took into account
    Heyer’s deafness and linguistic difficulties in evaluating the
    evidence.     Despite this factor, however, the court found the
    19
    opinions of Dr. Ross and Dr. Davis to be more persuasive on the
    determinative issues.
    Further, a review of the entire record demonstrates that
    the district court’s factual findings are not clearly erroneous.
    To determine whether Heyer currently suffered from a serious
    mental disorder, the district court properly quoted the criteria
    set out in the American Psychiatric Association’s Diagnostic and
    Statistical      Manual       of    Mental    Disorders,        Fourth    Edition,       Text
    Revision (“DSM-IV-TR”) concerning the definition of pedophilia.
    The   court     went     on   to     discuss      the   evaluations       of   all      three
    experts    on    this     subject,      including       Dr.     Heyer’s     expert,       Dr.
    Lytton.     In diagnosing Heyer with pedophilia, Dr. Davis placed
    great     weight    upon      Heyer’s        history      of    molestation       offenses
    against       prepubescent          children,       his        possession      of       child
    pornography,       his    demonstrated         sexual     arousal    to     prepubescent
    males     during    a     penile       plethysmograph           assessment,       and     his
    acknowledged sexual attraction to male children.                          Dr. Ross cited
    to Heyer’s self-report of engaging in pedophilic behaviors for a
    period of at least thirteen years, a penile plethysmograph that
    showed    the    greatest          arousal   response      to     males    ages     six    to
    eleven, and Heyer’s child pornography conviction.                          Finally, both
    Dr. Davis and Dr. Ross opined that pedophilia tends to be a
    chronic and life-long illness.
    20
    In contesting the validity of the diagnosis, Dr. Lytton
    reasoned that the penile plethysmograph tests produced results
    that the examiners described as clinically insignificant, that
    Heyer’s sexual offending pattern appears to have de-escalated as
    evidenced by his last contact offense having occurred in 1993,
    and that Heyer’s current sexual interests suggest that he is
    interested in consensual adult homosexual activities.
    The district court concluded that Dr. Ross’ and Dr. Davis’
    opinions    were   well-reasoned,    but    that   Dr.    Lytton      had   “not
    provided    a   persuasive    justification   as   to    why    Mr.   Heyer   no
    longer satisfies the relevant diagnostic criteria.” 6             (J.A. 523.)
    Absent     evidence    that    Heyer’s     pedophilia     had    “abated      or
    dissipated,” the district court concluded that the Government
    had met its burden by clear and convincing evidence that Heyer
    currently    suffers   from   pedophilia.      (J.A.    523.)      On   appeal,
    Heyer has cited no evidence upon which we can conclude that the
    opinions of Drs. Davis and Ross were unreasonable, and we thus
    cannot say that the district court clearly erred in crediting
    their opinions over Dr. Lytton’s.
    6
    Dr. Lytton acknowledged in her report that “Mr. Heyer’s
    criminal history includes past behaviors that suggest he may
    have met such criteria [for pedophilia] at that time.”   (J.A.
    631.)   In other words, Dr. Lytton acknowledges that Heyer was
    likely a pedophile in the past, but does not believe that he
    currently meets the criteria for that diagnosis.
    21
    The district court also properly considered the evidence
    and weighed the testimony of the experts in finding that the
    Government had established, by clear and convincing evidence,
    that    Heyer,       as    a     result     of    pedophilia,        “would      have       serious
    difficulty in refraining from sexually violent conduct or child
    molestation if released.”                   18 U.S.C. § 4247(a)(6).                  The experts
    considered       actuarial          tests,       psychological         tests,        and   Heyer’s
    individual circumstances to make clinical judgments based upon
    their       evaluations.              Viewed       in        light     of     his     individual
    circumstances and dynamic risk factors, the district court found
    that    Heyer’s       “actuarial          assessment         results        [we]re    consistent
    with his ongoing serious difficulty in refraining from sexually
    violent       conduct       or      child    molestation.”             (J.A.        525.)       The
    district court credited “the testimony and report of Dr. Davis,
    who focused on Heyer’s impulsivity, poor sexual self-regulation,
    and poor compliance with supervision when in the community,” as
    well    as    the    “evidence        of    Heyer’s      ongoing       sexual        interest    in
    children, as noted by Dr. Ross.”                        (J.A. 525.)          Heyer has failed
    to     show    that       the       opinions      of     Drs.    Davis        and     Ross     were
    unreasonable,         and      we    therefore         cannot    say    that     the       district
    court clearly erred in crediting their opinions.
    In     sum,    we       conclude     that       the    district       court’s        factual
    findings are a permissible and reasonable interpretation of the
    evidence presented at the hearing.                            Because we are not “left
    22
    with the definite and firm conviction that a mistake has been
    committed,” United States v. U.S. Gypsum Co., 
    333 U.S. 364
    , 395
    (1948), we cannot say that the district court clearly erred in
    finding that Heyer is a “sexually dangerous person” within the
    meaning of the Act.
    C.
    Finally, Heyer contends that the district court erred in
    rejecting   his    equal      protection     and        due   process      claims.
    Specifically, Heyer asserts that (1) section 4248 deprives him
    of his right to equal protection because it draws an improper
    classification     by   subjecting       BOP       individuals        to   § 4248
    commitment while exempting all others under federal control; and
    (2) the district court erred in holding that § 4248 is a civil,
    rather than criminal, statute and consequently, the statute is
    unconstitutional   on   the    grounds     that    it    fails   to   adequately
    protect various rights afforded to criminal defendants.
    Heyer’s claims are foreclosed by our decision in United
    States v. Timms, 
    664 F.3d 436
    (4th Cir. 2012), in which we
    plainly rejected both of the above-mentioned claims. 7                     As one
    panel of the Court may not overrule another panel, the Timms
    7
    Heyer acknowledges that his claims are foreclosed by
    Timms, but nevertheless “raises them here as a good faith
    argument for a change in the law and to preserve them for en
    banc or Supreme Court review.” (Opening Br. 42.)
    23
    decision is not reviewable unless a motion to rehear en banc is
    granted.   Gladhill v. Gen. Motors Corp., 
    743 F.2d 1049
    , 1050–51
    (4th Cir. 1984) (“As a single panel of this court, we lack
    authority to re-examine or to overrule [an existing decision in
    the circuit] short of an intervening Supreme Court decision” or
    en banc review.).    Accordingly, we conclude that the district
    court did not err in rejecting Heyer’s equal protection and due
    process claims.
    III.
    For the foregoing reasons, we affirm the judgment of the
    district court.
