    DUNCAN, Circuit Judge:
    The     government          brings   this     interlocutory            appeal   from      an
    order of the district court excluding grand jury testimony from
    use at trial without having found prosecutorial misconduct or
    bad faith in the underlying grand jury proceeding.                                    For the
    reasons that follow, we vacate the order and remand for further
    proceedings not inconsistent with this opinion.
    I.
    A.
    The grand jury investigation at issue here took place in
    October       2015,    but    relates      back     to     criminal      proceedings        that
    began    in    2014.         On    December    4,        2014,    a   federal      grand    jury
    indicted Maria Rosalba Alvarado McTague (“Alvarado”) and Felix
    Chujoy      (“Felix”)         on     charges        of     visa       fraud    and    various
    immigration       violations         stemming        from        their   operation         of    a
    Peruvian restaurant in Virginia.                         The indictment alleged that
    Alvarado smuggled immigrants into the United States to work in
    the restaurant.          It further alleged that both Alvarado and Felix
    employed these and other undocumented immigrants in horrendous
    and illegal working conditions, either paying them well below
    the     minimum       wage    or    requiring       them     to       work    as   indentured
    servants to repay Alvarado for smuggling them into the United
    States.
    3
    After their arrest, the district court released Alvarado
    and Felix on bond.                 As a condition of release, Alvarado and
    Felix could          not    contact       witnesses      or   alleged      victims    in     the
    case.
    During this time, a grand jury continued to investigate
    additional       charges           and     suspects.          In     expectation        of     a
    superseding          indictment,          the     parties     jointly       moved      for     a
    continuance.               The    district      court      granted        the   motion       and
    postponed trial to June 22, 2015.
    B.
    On March 12, 2015, the grand jury returned a superseding
    indictment.          The superseding indictment (1) charged Alvarado and
    Felix with additional labor trafficking counts, (2) added Gladys
    Chujoy--Felix’s sister and Alvarado’s daughter--as a defendant,
    and     (3)    charged       all       three    Defendants         with    obstruction       of
    justice, witness tampering, and conspiracy to witness tamper.
    The magistrate judge released Gladys Chujoy on bond, but revoked
    bond    for    Alvarado          and   Felix    after     finding    probable        cause    to
    believe       that    they       had     violated     their   conditions        of   release.
    Evidence suggested that Alvarado and Felix had been contacting
    witnesses using other people’s phones to avoid detection.                                  Over
    the    next     several          months,    the       government     investigated        these
    allegations by interviewing individuals whose telephone numbers
    appeared in witnesses’ cellphone records.
    4
    In May 2015, as part of this investigation, the government
    interviewed          several       friends      of     Alvarado       and       the     Chujoys,
    including Carolyn Edlind and Sheriff Donald Smith.                                     Based on
    those interviews, the government subpoenaed Edlind and Smith to
    testify at the upcoming trial.
    On    June     21,     2015,     due    to     a    personal        emergency,         the
    government moved for another continuance.                             The district court
    granted the motion, finding it to be in the interest of justice.
    So as not to adversely affect Alvarado and Felix, it ordered
    them released from jail on bond.                      Although Alvarado was obliged
    to   obtain        new      counsel,     Defendants        did      not     object       to    the
    continuance        and      explicitly      waived     any     potential        speedy        trial
    objection.         The district court scheduled the new trial date for
    October 26, 2015.
    In    late       August     2015,      counsel        for   an      inmate      at     the
    Rockingham County Jail invited the government to interview his
    client       about    information        concerning        Felix.         Felix        had    been
    incarcerated         at     the    Rockingham        County    Jail      with    this     inmate
    following his arrest on the superseding indictment.                                   The inmate
    revealed that he and other inmates had given Felix their PIN
    numbers       so     that    Felix      could    make      calls      from      jail     without
    detection.         The government obtained recorded conversations from
    the jail and discovered that Felix had placed at least eleven
    calls    from      May      2015   to   June    2015       using    other       inmates’       PIN
    5
    numbers.     Felix spoke with Smith on nine of those calls, and the
    conversations      provided       evidence          of   a    witness-tampering         scheme
    between Felix, Edlind, and Smith--information that Edlind and
    Smith did not disclose during their May 2015 interviews with
    federal law enforcement.
    C.
    Because      this    conduct       took        place       after     the     superseding
    indictment, the United States began a new investigation of Felix
    regarding witness tampering and obstruction of justice.                                      The
    government subpoenaed Edlind and Smith to testify when the next
    grand jury convened on October 6, 2015.                              Edlind’s and Smith’s
    testimony      provided        further    evidence            of    the    post-superseding
    indictment     witness-tampering              scheme.         The       government    promptly
    disclosed    the       grand    jury    evidence         to    the      district     court   and
    Defendants.
    On October 20, 2015, the government presented the grand
    jury with additional testimony and physical evidence concerning
    the   potential        witness-tampering            scheme     between       Felix,    Edlind,
    and   Smith.       That    same        day,    the       grand     jury     returned    a    new
    indictment       against       Felix      and       Edlind         on     multiple     counts,
    including conspiracy to witness tamper, witness tampering, and
    obstruction of justice.            The indictment also charged Edlind with
    perjury    and     a    second    count        of     obstruction          of    justice     for
    6
    allegedly      lying     during      her     grand     jury     testimony       about   her
    contact with Felix.
    In   response       to   this    new       information,       Alvarado    filed   a
    motion for a continuance to investigate possible prosecutorial
    misconduct      at    the     October    2015       grand    jury     proceedings.      The
    district court granted the continuance and set a new trial date
    of December 1, 2015.               In addition, the district court invited
    Defendants to file motions related to prosecutorial misconduct
    after    reviewing      the      grand     jury     transcripts       disclosed    by   the
    government.
    D.
    On November 13, 2015, Defendants filed a joint motion to
    dismiss all indictments, claiming that the government abused the
    October 2015 grand jury process by gathering evidence for the
    superseding indictment.              Specifically, Defendants alleged that
    the government called Edlind and Smith before the grand jury for
    the dominant purpose of gathering additional evidence against
    Defendants       on     the      superseding         indictment        and    discovering
    Defendants’ evidence and trial strategy.                            The district court
    denied       Defendants’         motion,       finding       that     no     prosecutorial
    misconduct occurred.
    The      district      court    nevertheless           limited    the    government’s
    use of October 2015 grand jury evidence at the upcoming trial on
    the superseding indictment.                 The district court concluded that
    7
    the government could not (1) call Edlind or Smith to testify in
    its case-in-chief as to any subjects covered in their October 6,
    2015, grand jury testimony, nor could it (2) use their grand
    jury testimony for any purposes at trial--including to impeach
    Edlind or Smith, if Defendants called them as witnesses.
    The    district      court        based    its   remedy       on    a        “unique
    combination      of     circumstances,”            which     it     found          to     be
    “fundamentally unfair.”            J.A. 460.        First, the district court
    found that several lines of questioning extended beyond the new
    witness     tampering      and     obstruction      charges       into    allegations
    underlying     the    original      charges.        J.A.     458.        Second,         the
    district    court     cited      “the   ongoing     delay”    occasioned           by    the
    second    continuance,      sought      by   the   government,      and     the         third
    continuance,     sought       by   Defendants.         J.A.       459.        It        bears
    repeating     that    in   addition       to     expressly    finding      that         “the
    government’s examination of Edlind and Smith did not go so far
    as to constitute misconduct,” J.A. 455, the district court also
    did   not     hold    that       the     government     engaged      in       bad-faith
    questioning or abused the grand jury process.
    The government appeals the district court’s order pursuant
    to 
    18 U.S.C. § 3731
     and 
    28 U.S.C. § 1291
    .
    8
    II.
    On appeal, the government argues that the district court
    abused    its    discretion   by   sanctioning    the   government     without
    finding prosecutorial misconduct.            According to the government,
    in the absence of such a finding, an evidentiary exclusion will
    never     lie.      Defendants     counter     that   the   district    court
    justifiably fashioned a limited evidentiary remedy to address
    fundamental unfairness.
    This court reviews a district court’s evidentiary rulings
    for abuse of discretion.           United States v. Hedgepeth, 
    418 F.3d 411
    , 418–19 (4th Cir. 2005).               Although this standard accords
    deference to the district courts, it does not insulate them from
    review.    A district court abuses its discretion when it (1) acts
    “arbitrarily, as if neither by rule nor discretion,” (2) fails
    to “adequately . . . take into account judicially recognized
    factors constraining its exercise” of discretion, or (3) rests
    its decision on “erroneous factual or legal premises.”               James v.
    Jacobson, 
    6 F.3d 233
    , 239 (4th Cir. 1993).
    We find that the district court abused its discretion in
    this case.       District courts have the supervisory duty to ensure
    that the grand jury “process is not abused or used for purposes
    of oppression or injustice.”          United States v. U.S. Dist. Court
    for S. Dist. of W. Va., 
    238 F.2d 713
    , 722 (4th Cir. 1956).                 But
    a district court must provide a sufficient explanation for its
    9
    decisions in furtherance of that duty to provide a meaningful
    basis for review. See Jacobson, 
    6 F.3d at
    239–40.                     That is what
    the district court failed to do here.                  As we explain below, its
    stated reasons do not comport with our precedent or the facts of
    record,    and   its     conclusion      regarding       “fundamental       fairness”
    provides    no      legal      standard         by     which     to   measure      the
    appropriateness of the evidentiary exclusion.
    We nevertheless reject the government’s argument that the
    district court may never exclude grand jury evidence except as a
    sanction for prosecutorial misconduct.                   The absence of such a
    finding,    however,        makes   it    particularly         incumbent    upon   the
    district    court      to   explain      both    the    reasoning     for    and   the
    parameters of any exclusion of evidence derived from grand jury
    proceedings.
    We begin by considering our precedent on grand jury abuse.
    We then consider the district court’s stated reasons for the
    evidentiary exclusion in light of that precedent.                     And finally,
    we address the government’s argument for a categorical rule.
    A.
    Under our precedent on grand jury abuse, this court adheres
    to “the universal rule” that prosecutors cannot use grand jury
    proceedings for the “sole or dominant purpose” of preparing for
    trial on an already pending indictment.                   United States v. Moss,
    
    756 F.2d 329
    , 332 (4th Cir. 1985).                   For example, the government
    10
    may not use the grand jury to improve its case in an already
    pending trial by preserving witness statements, locking in a
    witness’s    testimony,              pressuring         potential       trial       witnesses      to
    testify favorably, or otherwise employing the grand jury for
    pretrial discovery. See 
    id.
     at 331–32 (collecting cases).                                           In
    short,     “once     a     criminal          defendant          has     been     indicted,        the
    Government is barred from employing the grand jury for the ‘sole
    or dominant purpose’ of developing additional evidence against
    the defendant.”            United States v. Bros. Constr. Co. of Ohio,
    
    219 F.3d 300
    ,        314        (4th    Cir.        2000)(quoting          Moss,       
    756 F.2d at 332
    ).     A district court has discretion to take appropriate
    remedial action where it finds grand jury abuse in the form of
    an   improper      sole        or    dominant       purpose.          See    United     States      v.
    Brinkman, 
    739 F.2d 977
    , 980 (4th Cir. 1984).                                Here, the district
    court did not find an improper sole or dominant purpose, but
    nevertheless         determined            there        was     a     need     to     fashion      an
    evidentiary remedy based on perceived fundamental unfairness.
    However,       to        protect       the         grand       jury’s        investigative
    function,    this        court       has    repeatedly          recognized          that    district
    courts should refrain from intervening in the grand jury process
    absent   compelling            evidence      of     grand      jury     abuse.         See,      e.g.,
    Moss, 
    756 F.2d at
    331–32.                    Defendants alleging grand jury abuse
    bear   the   burden        of       rebutting       the       “presumption       of     regularity
    attache[d]      to    a    grand           jury’s       proceeding.”            Bros.       Constr.,
    11
    
    219 F.3d at 314
         (quoting        Moss,     
    756 F.2d at 332
    ).           This
    presumption is further strengthened where, as here, a grand jury
    returns new indictments with additional charges or defendants.
    See   Moss,      
    756 F.2d at
    332–33.        Indeed,     some      of    our   sister
    circuits have gone so far as to hold that the government has an
    automatic safe harbor when the superseding indictment adds new
    charges or new defendants.                 See, e.g., United States v. Flemmi,
    
    245 F.3d 24
    , 30 (1st Cir. 2001).
    Although our circuit has not applied such a per se rule,
    the   fact     that    new     indictments         issued     is     a    circumstance       a
    district      court    should        factor      into   its    overall         analysis      as
    militating in favor of the government, not just in determining
    the dominant purpose of the grand jury proceeding, but also in
    crafting an evidentiary remedy.                  “The function of the grand jury
    is to inquire into all information that might possibly bear on
    its   investigation        until     it    has     identified       an   offense      or   has
    satisfied     itself     that       none   has     occurred.”        United      States     v.
    R. Enters.,        Inc.,      
    498 U.S. 292
    ,   297     (1991).           Such       an
    investigation requires broad and thorough examination of grand
    jury witnesses.          United States v. Dionisio, 
    410 U.S. 1
    , 12–13
    (1973).
    When there is a pending indictment, grand jury witnesses
    often     have     information         pertinent        to    both       already-indicted
    charges and new charges.                   The grand jury is not required to
    12
    disregard the former when investigating the latter.                        “Lacking
    clairvoyance, grand juries must be allowed to investigate freely
    individuals      suspected     of   involvement      in     crimes       for    which
    indictments have already been issued.”               Moss, 
    756 F.2d at 332
    .
    An already-indicted defendant is not insulated from a grand jury
    investigation     into   new    offenses    committed       after    the       initial
    indictment.      
    Id.
     at 331–32.       A grand jury in such a situation
    must perform the same broad and thorough investigation required
    of all grand juries.         See Blair v. United States, 
    250 U.S. 273
    ,
    282    (1919)   (“As   has   been   said   before,    the     identity         of   the
    offender, and the precise nature of the offense, if there be
    one,   normally    are   developed    at    the    conclusion       of   the    grand
    jury's labors, not at the beginning.”).                A district court has
    some supervisory authority over these proceedings, but it should
    not restrict grand jury evidence arising out of “a good-faith
    inquiry   into    charges    that   are    not    covered    in   the     [initial]
    indictment.”      Bros. Constr., 
    219 F.3d at 314
    .
    B.
    In light of this precedent, we next examine the district
    court’s proffered reasons for its exclusion of evidence remedy:
    (1) the scope of questions asked at the October 2015 grand jury
    proceeding and (2) “ongoing delay” occasioned by the second and
    third trial continuances.           We are compelled to conclude that
    neither reason justifies the district court’s remedy.
    13
    1.
    Part of the perceived necessity for a remedy arose from the
    district court’s finding that “a not-insignificant portion of
    the   questions      asked   at    the    October        grand     jury      session      went
    beyond the subject of witness tampering and obstruction, and
    delved into information probative to the underlying charges.”
    J.A. 458.       The district court also noted that “questions asked
    about conversations between the witnesses and defense counsel
    [were]     of   particular        concern.            Because      so     many      of     the
    government’s questions addressed issues closely intertwined with
    the   underlying     charges,      including         a   potential       trial      defense,
    some evidentiary restriction [was] needed.”                      J.A. 458.
    The reasoning underlying the district court’s observations
    is obscure and does not provide a basis upon which appellate
    review   can    be   conducted.          The    opinion       fails     to    explain      the
    relevance of the fact that the government’s questioning may have
    been “closely intertwined with the underlying charges” to the
    determination of whether the questions arose out of “a good-
    faith    inquiry     into    charges      that       [were]    not      covered      in    the
    indictment.”         Bros.    Constr.,         
    219 F.3d at 314
    .        Uncovering
    evidence    against    an    already-indicted            person      does     not   provide
    ipso facto evidence that the government failed to conduct its
    questioning in good faith.                Moss, 
    756 F.2d at 332
    .                    In this
    regard, the district court’s opinion fails to explain how it
    14
    factored the issuance of the new indictments into its analysis
    of any ground for an evidentiary remedy.     Again, broader lines
    of questioning help determine what charges are appropriate, and
    which suspects should be tried.      R. Enters., 
    498 U.S. at 297
    .
    Incidental benefits alone cannot justify exclusion of grand jury
    evidence.   See Moss, 
    756 F.2d at 332
    ; United States v. (Under
    Seal), 
    714 F.2d 347
    , 350 (4th Cir. 1983).      The district court
    abused its discretion when it based its evidentiary exclusion
    partially on the grounds that some questions “seem[ed] to stray
    far afield of the new allegations,” J.A. 455, without providing
    a legal justification for so doing. 1
    2.
    The district court also stated that the delay occasioned by
    two of the trial continuances supported its evidentiary remedy.
    J.A. 459–60.   But like the discussion about the scope of the
    1  Furthermore, the district court’s reliance on Brothers
    Construction as authority to the contrary is misplaced.     Like
    the district court in our case, the district court in Brothers
    Construction limited evidentiary use of some testimony without
    finding prosecutorial misconduct. 
    219 F.3d at
    313–14. However,
    in Brothers Construction, these evidentiary rulings were not at
    issue on appeal.     Moreover, the district court in Brothers
    Construction did not explain the legal basis for its evidentiary
    rulings, and the only other reference to these rulings occurs in
    a trial transcript.    J.A. 458 n.3.   Likewise, that transcript
    also fails to offer legal justification for the district court’s
    exclusion, noting only that the district court planned to
    exclude    some  evidence.      One  district   court’s  legally
    unsubstantiated remedy does not justify another district court’s
    legally unsubstantiated remedy.
    15
    government’s questioning, we cannot discern from the district
    court’s opinion how the government’s conduct in relation to the
    continuances supported the district court’s remedy.
    The first cited continuance resulted from the government’s
    emergency motion in June 2015.              The district court noted that
    this   continuance   caused     the   delay    that   required   Alvarado    to
    obtain new counsel.       However, as we have noted, Defendants were
    released   from   jail    to   minimize     any   adverse   effect   on   them.
    Moreover, while the district court is responsible for balancing
    prejudice to defendants in granting a continuance, United States
    v. LaRouche, 
    896 F.2d 815
    , 823–25 (4th Cir. 1990), the district
    court here found that granting the continuance would be in the
    interest of justice.           The district court must explain why a
    delay it found fully justified at the time, now supports an
    evidentiary remedy.
    The district court further stated that “[i]n granting the
    government’s motion for a continuance in June, the court did not
    expect that the government would undertake to develop additional
    evidence for use at trial.”           J.A. 460.    This statement, too, is
    perplexing; how it relates to Defendants’ claims of grand jury
    abuse is not clear.       The district court did not explicitly state
    that the government used the October 2015 grand jury hearing to
    develop    additional     evidence      for    already-indicted      offenses;
    indeed,    in   finding   neither     prosecutorial    misconduct     nor   bad
    16
    faith the district court suggests to the contrary.                                    We fail to
    see,     and     the       district          court       fails      to   explain,          how    the
    government’s preparation for trial otherwise has any bearing on
    the district court’s conclusion that an evidentiary exclusion
    was required.
    The     only       other       motion      for    a    continuance          cited    by   the
    district       court       as     a    basis       for       its    evidentiary       remedy       is
    Alvarado’s.           J.A. 459–60.             To justify reliance on Alvarado’s
    motion for a continuance to impose evidentiary sanctions on the
    government, the district court attributes the impetus for the
    motion to the October 2015 indictment.                             This rationale fails for
    the same reason that the government’s motion for a continuance
    does: the district court does not explain how the government
    engaged in anything other than a good-faith inquiry into new
    charges.       Citing the indictment alone for evidence of grand jury
    abuse directly contradicts our prior holding that an indictment
    provides strong evidence of a proper purpose.                                      See Moss, 
    756 F.2d at
    332–33.
    In the absence of a tenable explanation we are left to
    infer     that        the       district          court       perceived        a     pattern      of
    questionable behavior on the part of the government motivating
    the    delay.         However,         the     district       court      did   not    explicitly
    detail       such     a     finding,         or    for       that     matter       specify       what
    government conduct was impermissible.                              This court will not read
    17
    between      the      lines     to    affirm       an     order       that       affects    the
    independence accorded to the grand jury’s investigative process.
    If   new    evidence     came    to    the   district       court’s          attention     that
    prosecutorial         misconduct       or    bad        faith     contributed         to   the
    circumstances         causing     either     continuance,             then    the    district
    court    must    state    so    in    its    opinion.           See   In     re   Grand    Jury
    Subpoena,       
    175 F.3d 332
    ,   337–38       (4th    Cir.       1999)(finding        that
    timing of events could be one factor a district court considers
    in deciding whether sufficient prosecutorial misconduct exists
    to justify quashing a grand jury subpoena).                           The district court
    abused its discretion in citing delay as a justification for its
    remedy without explaining how the delay related to alleged grand
    jury    abuse      and   why     a    remedy      of    evidentiary          exclusion     was
    appropriate.
    C.
    On appeal the government not only argues that the district
    court lacked a justification for its remedy, but also takes the
    further step of urging us to hold that a district court has no
    power to issue a remedy when it finds a proper dominant purpose.
    Although     the      Fourth    Circuit      has    not    squarely          confronted     the
    issue, at least one other circuit has taken such a stance.                                  See
    United States v. US Infrastructure, Inc., 
    576 F.3d 1195
    , 1215
    (11th Cir. 2009) (rejecting the defendants’ claims of grand jury
    abuse      “[b]ecause     the    government        did    not     use      the    grand    jury
    18
    ‘primarily’    to    obtain   evidence”         related     to    prior      indictments
    where most of the questioning related to new charges).
    We nevertheless decline to adopt the government’s position.
    Our    precedent     “forbids”      the        government        from     engaging    in
    impermissible questioning during a grand jury proceeding.                             See
    In    re   Grand    Jury   Proceedings         No.   92-4,       
    42 F.3d 876
    ,    878
    (4th Cir. 1994) (“This prohibition bars, inter alia, grand jury
    requests that amount to civil or criminal discovery, as well as
    arbitrary,     malicious,      or     harassing           inquiries.”         (internal
    citation omitted)).        We are not prepared to say that there could
    be no circumstances in which the government has undertaken a
    line of questioning that falls just short of impermissibility
    but nevertheless calls for some remedial action.                          See id.; see
    also United States v. Doe, 
    455 F.2d 1270
    , 1276 (1st Cir. 1972).
    District courts must be vested with some discretion to remedy
    conduct they find troubling even if the conduct does not rise to
    the level of misconduct.         A defendant claiming grand jury abuse
    faces an uphill climb, but this court will not render the hill
    insurmountable.
    It is simply that, on these facts, the district court has
    provided us with no navigational aids.                Where the district court
    cannot conclude the government employed the grand jury for an
    improper     sole    or    dominant   purpose,         it    becomes         even    more
    incumbent upon the district court to state with particularity
    19
    what    it   found    troubling,     and    how        it   tailored     its    remedy   to
    correct that finding.             Otherwise such exclusions risk chilling
    proper uses of the grand jury.
    The instant case presents an apt example.                        The nature of
    questioning       for    a   grand       jury    investigating          obstruction       of
    justice      or   witness    tampering          will    necessarily       require     some
    inquiry into the facts of the underlying, ongoing case.                             As the
    district     court      itself   recognized,       “questions          that    touched    on
    Edlind’s      and     Smith’s    prior     contact          with   Alvarado,      [Felix]
    Chujoy, and [Gladys] Chujoy have a credible relationship with
    the new allegations of witness tampering.”                      J.A. 455.       It is for
    this reason that the district court found that Defendants had
    not met their heavy burden of demonstrating “that the government
    questioned Edlind or Smith with the sole or dominant purpose of
    preparing for trial on the superseding indictment.”                             J.A. 457.
    The record supported this conclusion.
    Yet the district court continued, finding it “necessary to
    fashion an appropriate evidentiary remedy.”                        J.A. 457.        But to
    fashion an appropriate remedy the district court must identify
    with    specificity       what    troubling        circumstances         justified       its
    evidentiary         exclusion,     and     how     it       narrowly     tailored     that
    exclusion to prevent sweeping up evidence that arose from good-
    faith     questioning.           Holding    otherwise          would     disregard       the
    principle that “the law presumes, absent a strong showing to the
    20
    contrary, that a grand jury acts within the legitimate scope of
    its authority.”       R. Enters., 
    498 U.S. at 300
    .
    III.
    What undergirds our decision today is the presumption of
    regularity attached to grand jury proceedings.                    In cases like
    the   present    one,      the    fact    that    a   challenged       grand     jury
    proceeding returns new indictments renders this presumption even
    stronger.     This court will not affirm an order overriding that
    presumption     on   the   basis    of    mere   concerns     divorced    from   any
    recognized legal justification.
    Therefore,      we   hold    that    the   district     court    abused    its
    discretion.      On    remand,     the    district    court   should     allow   the
    government to use Edlind’s and Smith’s grand jury testimony or
    explain with specificity both the legal basis for its exclusion,
    and how its sanction is narrowly tailored to that concern.                        For
    the reasons stated above, we vacate the order and remand for
    further proceedings not inconsistent with this opinion.
