    Opinion En Banc
    December 23, 2015
    - 3 -
    The   judgments    entered    in    the    district   courts   are
    affirmed by an equally divided en banc court.            See Savard v. Rhode
    Island, 
    338 F.3d 23
    , 25 (1st Cir. 2003) (en banc).
    Opinions follow.
    BARRON, Circuit Judge, with whom TORRUELLA and THOMPSON,
    Circuit Judges, join. Congress has long given the Attorney General
    discretion to decide whether to take aliens who are subject to
    removal into immigration custody.             Congress also has long given
    the Attorney General discretion to decide whether to release on
    bond aliens who are in immigration custody while their removal
    proceedings   are   pending.     Nearly       thirty   years   ago,   however,
    Congress began enacting a succession of similar but slightly
    revised immigration detention mandates that limited the Attorney
    General's    detention   discretion      in    certain   respects.       These
    consolidated appeals require us to decide the scope of the present
    version of this detention mandate, codified in 8 U.S.C § 1226(c).
    Much like its precursors, this detention mandate first
    directs that the Attorney General shall take into custody certain
    "criminal aliens" -- as defined by their commission of specified
    offenses -- "when [they are] released" from criminal custody. And,
    much like its precursors, this detention mandate then bars the
    Attorney General from releasing certain aliens on bond once they
    have been placed in immigration custody.           The key point of dispute
    - 4 -
    concerns the class of aliens to whom this bar to bonded release
    applies.
    We    conclude   that   Congress   intended   for   the   present
    detention mandate to operate like its precursors and thus that its
    bar to bonded release applies only to those specified criminal
    aliens whom the Attorney General took into custody "when [they
    were] released" from criminal custody.           We further conclude that
    the two aliens who bring these habeas petitions were not taken
    into immigration custody "when [they were] released" from criminal
    custody because they had been released from criminal custody years
    before their immigration custody started. As a result, we conclude
    that the present detention mandate does not bar either petitioner
    from seeking release on bond pursuant to the Attorney General's
    discretionary release authority.
    Two district courts of this Circuit reached the same
    conclusion        in   granting   the   petitioners    the   right     to   an
    individualized bond hearing at which they could seek release prior
    to the completion of the removal process.           See Gordon v. Johnson,
    
    991 F. Supp. 2d 258
    (D. Mass. 2013); Castañeda v. Souza, 952 F.
    Supp. 2d 307 (D. Mass. 2013).           A panel of this Circuit affirmed.
    See Castañeda v. Souza, 
    769 F.3d 32
    (1st Cir. 2014).              This Court
    then agreed to rehear the case en banc, and is now, by a vote of
    three to three, evenly divided.          In consequence, the judgments of
    the district courts are affirmed, as we believe they should be
    - 5 -
    given       Congress's   evident      intention    not    to    deny   aliens   like
    petitioners the chance to seek bonded release, the consequential
    nature of the decision to deny aliens such a chance, and the
    reality that removal proceedings can stretch on for months or even
    years.
    I.
    The key parts of the Immigration and Naturalization Act
    are   codified     in    8   U.S.C.    §   1226,   and,    in    particular,     two
    subsections of it: (a) and (c).1            Through subsection (a), Congress
    gave the Attorney General broad discretion to decide whether to
    take into custody an alien who is in the removal process. Congress
    also gave the Attorney General, through that same subsection, broad
    discretion to release on bond those aliens whom she had placed in
    custody so that they would not have to be detained for the often
    lengthy removal process.2
    1
    This authorization, located in 8 U.S.C. § 1226(a), provides:
    "On a warrant issued by the Attorney General, an alien may be
    arrested and detained pending a decision on whether the alien is
    to be removed from the United States. Except as provided in
    subsection (c) of this section and pending such decision, the
    Attorney General . . . may continue to detain the arrested
    alien . . . and . . . may release the alien on . . . bond . . . ."
    2 Although the Attorney General now shares responsibilities
    under § 1226(a) with the Secretary of Homeland Security and the
    Under Secretary for Border and Transportation Security, see
    Homeland Security Act of 2002, Pub. L. No. 107–296, §§ 402, 441,
    116 Stat. 2135, we will for convenience refer to this authority as
    being vested in the Attorney General.
    - 6 -
    To    govern   the   exercise     of   this   release    power,   the
    Attorney General issued regulations pursuant to subsection (a).
    These regulations authorize immigration judges (subject to review
    by the Board of Immigration Appeals (BIA) and ultimately the
    Attorney General) to make individualized bond determinations based
    on a detainee's flight risk and danger to the community.                See 8
    C.F.R. § 1236.1(c)(8), (d)(1), and (d)(3).
    As    a   result     of   §   1226(a)    and    its     implementing
    regulations, these two petitioners, Leiticia Castañeda and Clayton
    Gordon, plainly may be detained for the entirety of the removal
    process if they are found to pose sufficient bond risks.              There is
    a question, however, whether they must be detained for the entirety
    of that process regardless of the showing they could make at a
    bond hearing.
    The question arises due to the contested scope of the
    limited exception to § 1226(a) that is carved out by § 1226(c).
    The exception appears in two paragraphs of subsection (c) under
    the single heading, "Detention of Criminal Aliens."3
    3 Section 1226(c) provides:
    (c) Detention of criminal aliens
    (1) Custody
    The Attorney General shall take into custody any alien who--
    (A) is inadmissible by reason of having committed
    any offense covered in [8 U.S.C. § 1182(a)(2)],
    (B) is deportable by reason of having committed any
    offense covered in [8 U.S.C. § 1227(a)(2)(A)(ii)-
    (iii),(B)-(D)],
    - 7 -
    Together, the paragraphs establish the latest version of
    a detention mandate Congress first enacted in 1988.             Illegal
    Immigration   Reform   and   Immigrant   Responsibility   Act   of   1996
    (IIRIRA), tit. 111 § 303, Pub. L. No. 104-208, 110 Stat. 3009-546,
    3009-585.   In each prior version, Congress required first that the
    Attorney General "shall take into [immigration] custody any alien
    convicted" of an enumerated felony offense "upon completion" of
    the alien's sentence (1988 mandate) or "upon [the alien's] release"
    from criminal custody (later mandates).          And, in each prior
    version, Congress then required that the Attorney General "shall
    not release such felon from [immigration] custody."       See Anti-Drug
    Abuse Amendments Act of 1988, § 7343(a), Pub. L. No. 100-690, 102
    Stat. 4181, 4470; Immigration Act of 1990, § 504(a), Pub. L. No.
    101-649, 104 Stat. 4978, 5049-50; Antiterrorism and Effective
    (C)     is    deportable     under    [8     U.S.C.
    § 1227(a)(2)(A)(i)] on the basis of an offense for which
    the alien has been sentenced to a term of imprisonment
    of at least 1 year, or
    (D)    is    inadmissible     under    [8    U.S.C.
    § 1182(a)(3)(B)] or deportable under [8 U.S.C.
    § 1227(a)(4)(B)],
    when the alien is released, without regard to whether the
    alien is released on parole, supervised release, or
    probation, and without regard to whether the alien may be
    arrested or imprisoned again for the same offense.
    (2) Release
    The Attorney General may release an alien described in
    paragraph (1) only if . . . release of the alien from custody
    is necessary to provide protection to a witness . . . .
    - 8 -
    Death Penalty Act of 1996 (AEDPA), § 440(c), Pub. L. No. 104-132,
    110 Stat. 1214, 1277.
    The version of the detention mandate that is at issue
    here was enacted in 1996 and follows this same structure.      The
    first paragraph, identified as § 1226(c)(1), appears under the
    heading "Custody."      Like the portion of the earlier enacted
    detention mandates that contained the "upon completion" or "upon
    release" clauses, this paragraph sets forth the following custody
    directive: the Attorney General "shall take into [immigration]
    custody" an alien who has committed certain offenses or engaged in
    certain concerning behavior -- specified in subparagraphs (A)-(D)
    of (c)(1) -- "when the alien is released, without regard to whether
    the alien is released on parole, supervised release, or probation
    . . . ."4
    4 As these petitioners were released from prison sentences,
    there is no question they were "released" within the meaning of
    § 1226(c)(1). With respect to the precise requirement the word
    "released" imposes, the Second Circuit recently held in Lora v.
    Shanahan that a convicted alien who receives a non-carceral
    sentence has also been "released."      Lora v. Shanahan, 
    2015 WL 6499951
    , at *6 (2d Cir. Oct. 28, 2015).         The Second Circuit
    concluded that this interpretation of "released" "avoids
    nullifying" the trailing language in (c)(1), which, through its
    reference to "probation," "clearly contemplates non-carceral
    sentences."    
    Id. In effect,
    the Second Circuit interprets
    "released" to mean "release from the technical custody of the
    criminal court" (i.e., at the end of the sentencing proceeding),
    a position that the government has elsewhere advanced. See In re
    West, 22 I. & N. Dec. 1405, 1408 (BIA 2000). In so doing, the
    Second Circuit did not address the BIA's view that "released" means
    even release from pre-conviction arrest. See In re Kotliar, 24 I.
    - 9 -
    The   second   paragraph,    identified    as   §   1226(c)(2),
    follows   directly   after   (c)(1)   and   appears   under    the   heading
    "Release."    Like the portion of the earlier enacted detention
    mandates that contained the "such felon" clause, this paragraph
    sets forth the following bar to bonded release from immigration
    custody: the Attorney General "may release an alien described in
    paragraph (1) only if" the alien satisfies certain limited criteria
    not at issue here.5
    Under petitioners' view, (c)(1) and (c)(2) operate in
    tandem just as the earlier detention mandates did.         In consequence
    of the words "when" and "released" in the first paragraph, the
    Attorney General must timely take specified aliens coming out of
    criminal custody into immigration custody.        The second paragraph,
    by referring to the prior paragraph, then requires the Attorney
    General not to release on bond the specified aliens that she has
    timely taken into immigration custody following their release from
    criminal custody in accordance with the directive in (c)(1).
    & N. Dec. 124, 125 (BIA 2007); West, 22 I. & N. Dec. at 1410; see
    also 
    Saysana, 590 F.3d at 14
    (suggesting, more broadly, that an
    alien could be arrested and not convicted and yet still fall within
    § 1226).
    5 Aliens taken into custody pursuant to § 1226(c) are entitled
    to a "Joseph" hearing at which the alien "may avoid mandatory
    detention by demonstrating that he is not an alien, was not
    convicted of the predicate crime, or that [U.S. Immigrations and
    Customs Enforcement] is otherwise substantially unlikely to
    establish that he is in fact subject to mandatory detention."
    Demore v. Kim, 
    538 U.S. 510
    , 514 n.3 (2003).
    - 10 -
    Petitioners contend that this reading of § 1226(c) makes
    sense not only as a matter of text, structure, and history, but
    also on its own terms.         Petitioners point to the substantive
    differences      between   aliens    taken       into   immigration     custody
    "when . . . released" from criminal custody and those aliens who
    are taken into immigration custody some time after they have been
    "released" from criminal custody.         Petitioners emphasize that "the
    experience of having one's liberty stripped away is drastically
    different from the experience of not having it restored."                   See
    Castañeda v. Souza, 
    952 F. Supp. 2d 307
    , 318 n.10 (D. Mass. 2013).
    They also note that their intervening period of freedom makes it
    possible    to    take   account    of   their    post-release   conduct     in
    evaluating the flight risk or danger they may pose.6                  And amici
    contend that Congress had practical reasons to limit the scope of
    the mandate in this way, given resource constraints on detention
    capacity.        See Amicus Br. of Frm. Imm. Judges and DHS Sec.
    Officials at 17-20.
    On the basis of this reading of § 1226(c), petitioners
    contend that the exception to § 1226(a) that (c) carves out does
    not apply to them due to the remoteness of their release from
    6 For example, since his release from criminal custody in
    2008, petitioner Clayton Gordon has become a father, bought a
    house, developed a successful business, and worked on a project to
    open up a halfway house for women. 
    Castañeda, 769 F.3d at 40

    criminal custody.7       Accordingly, petitioners argue they may seek
    discretionary release on bond under (a) just like any other alien
    placed   in    custody   by   the   Attorney   General   pursuant   to   that
    subsection.
    The government counters that petitioners' argument fails
    at the threshold on the basis of the interpretation of § 1226(c)(2)
    that the BIA set forth in In re Rojas, 23 I. & N. Dec. 117 (BIA
    2001).   The BIA held in Rojas that only subparagraphs (A)-(D) of
    (c)(1) (which enumerate predicate offenses and other qualifying
    misconduct) limit (c)(2).       Rojas thus makes the rest of (c)(1) --
    including the "when . . . released" clause and its trailing
    language specifying what counts as a "release[]" from criminal
    custody -- irrelevant to the application of (c)(2).          See Rojas, 23
    I. & N. Dec. at 121 ("The 'when released' clause is no more a part
    of the description of an alien who is subject to detention than
    are the other concluding clauses." (emphasis in original)).
    7 Leiticia Castaneda, a native of Brazil, was arrested in
    Massachusetts for misdemeanor possession of cocaine, sentenced to
    probation, and released from custody in 2008. 
    Castañeda, 769 F.3d at 39
    .   Clayton Gordon, a native of Jamaica, was arrested in
    Connecticut for possession of cocaine with intent to distribute
    and was thereupon released from custody in 2008.      
    Id. at 40.
    Gordon subsequently pled guilty and received a suspended prison
    sentence and three-year probationary term in 2009. More than four
    years after their respective releases from criminal custody, the
    government took each of the petitioners into immigration custody
    and charged them with removal due to their convictions. 
    Id. - 12
    -
    The   government     contends   we   must   defer   to   Rojas's
    conclusion    that    whatever    limitations    the    words   "when"    and
    "released" impose on § 1226(c)(1) do not matter for (c)(2) because
    the text of (c)(2) is not clear on that key point.          The government
    claims we must do so because Rojas reasonably construed (c)(2) to
    reduce the chance that an alien with an (A)-(D) offense might be
    released due to a mistaken evaluation of bond risk. The government
    therefore    argues   that    Rojas   requires   petitioners'     mandatory
    detention without bond -- notwithstanding their years of living
    freely -- because each petitioner committed an (A)-(D) offense and
    nothing more is required for (c)(2) to apply.
    In the alternative, the government asserts that even if
    Rojas is wrong and the "when . . . released" clause is relevant to
    (c)(2), the petitioners were in fact taken into immigration custody
    "when . . . released."       The government argues that the word "when"
    is best read in context to mean "if" or "any time after."                As a
    fallback, the government argues that the word "when" at most
    triggers a duty to act promptly that persists indefinitely. Either
    way, the government argues, § 1226(c)(2) applies to aliens with
    predicate offenses who were taken into immigration custody even
    years after their release from criminal custody.8
    8 After the panel ruled for the petitioners, the government
    scheduled bond hearings for each one.    Before Castañeda's bond
    hearing took place, the government, of its own accord, concluded
    - 13 -
    We consider each argument in turn.   We explain first why
    we conclude that the "when . . . released" clause in § 1226(c)(1)
    also modifies the scope of (c)(2). We then explain why we conclude
    that the "when . . . released" clause imposes a deadline for
    picking up an alien coming out of criminal custody that limits the
    application of (c)(2)'s bar to bonded release.9
    II.
    We start with the question whether we must defer to
    Rojas's   reading     of   §    1226(c)(2),    under   which   the
    "when . . . released" clause in (c)(1) is wholly irrelevant to the
    scope of (c)(2).    In undertaking this inquiry, we apply the two-
    that she did not pose a flight risk or a danger to the community
    and released her.    Gordon, by contrast, made his case to an
    immigration judge at a bond hearing, prevailed, and was released
    as well. These decisions to release the petitioners do not render
    the present appeal moot. See Sylvain v. Attorney Gen. of U.S.,
    
    714 F.3d 150
    , 161 n.12 (3d Cir. 2013).
    9 Four other circuits have addressed the issues we address
    here. In Hosh v. Lucero, 
    680 F.3d 375
    , 378-381 (4th Cir. 2012),
    the Fourth Circuit claimed to defer to Rojas. But, contra Rojas,
    Hosh actually assumed the "when . . . released" clause limited
    § 1226(c)(2) and concluded that the word "when" is not time-
    limited -- a view that the BIA has never adopted. In Sylvain v.
    Attorney Gen. of U.S., 
    714 F.3d 150
    , 161 (3d Cir. 2013), the Third
    Circuit avoided deciding the meaning of "an alien described in
    paragraph (1)" by holding for the government on the basis of loss-
    of-authority principles. More recently, in Olmos v. Holder, 
    780 F.3d 1313
    , 1324 (10th Cir. 2015), the Tenth Circuit deferred to
    Rojas, as did the Second Circuit in in Lora, 
    2015 WL 6499951
    , at
    *6. Numerous district courts have addressed the issue, and most
    have gone the other way. See Immig. Law Profs. et al. Amicus Br.
    at A-xxii-xxix (assembling eighty-nine cases that have rejected

    step test set forth in Chevron, U.S.A., Inc. v. Natural Resources
    Defense Council, Inc., 
    467 U.S. 837
    (1984).     At step one, we must
    decide whether Congress spoke clearly to the precise question at
    issue.    
    Id. at 842.
      If so, that ends the matter.   
    Id. at 842-43.
    If not, then, at step two, we must defer to the administering
    agency's interpretation if it is reasonable.     
    Id. at 843.
    Our focus is on step one, which is where we conclude
    Rojas went wrong.10     For while Chevron is a famous doctrine, much
    precedent cautions us not to be so star-struck by it that we must
    defer to the agency at the first sign of uncertainty about the
    meaning of the words that Congress chose.     Rather, under Chevron,
    we must be mindful that "a statute may foreclose an agency's
    preferred interpretation despite such textual ambiguities if its
    structure, legislative history, or purpose makes clear what its
    text leaves opaque."       See Council for Urological Interests v.
    Burwell,

    , 221 (D.C. Cir. 2015) (quoting Catawba Cnty.,

    step one depends on "how judges identify the precise question at
    issue, since at one level of generality the statute may answer it
    under Chevron step one, but at [another] level there may be an
    ambiguity"). Because we conclude that Congress spoke clearly to
    the relationship between § 1226(c)(1) and (c)(2), and because the
    precise issue Rojas decided concerned that relationship, we
    resolve this issue under step one.

    plainly intended for the "when . . . released" clause in (c)(1) to
    apply to (c)(2) as well.

    A.
    Rojas identified a clear choice between two possible
    readings of the words in the cross-reference in § 1226(c)(2), "an
    alien described in paragraph (1)."        See Rojas, 23 I. & N. Dec. at
    119.    Given the text of the cross-reference, the alien to whom
    (c)(2) refers is either (as Rojas held) an alien who has committed
    an offense specified in subparagraphs (A)-(D) of (c)(1) or (as
    petitioners contend) an alien who was taken into custody pursuant
    to the duty imposed by paragraph (1) as a whole.
    This choice matters because it determines whether the
    "when . . . released" clause -- and whatever limits it imposes
    through the words "when" and "released" -- modifies the scope of
    § 1226(c)(2).   If "an alien described in paragraph (1)" refers to
    an alien who was taken into custody pursuant to the duty imposed
    by (c)(1) as a whole, then the cross-reference would not merely
    refer to an alien who has committed an (A)-(D) offense.          It would
    instead refer to an alien who has committed an (A)-(D) offense and
    whom the Attorney General took into immigration custody "when" the
    alien    was    "released"   from        criminal   custody,     as   the
    "when . . . released" clause sets forth the conditions under which
    that duty applies.   Rojas, 23 I. & N. Dec. at 121-22.         And (c)(2),
    then, would come into play as a bar to the release of only those
    aliens picked up after the duty in (c)(1) had been discharged.
    See 
    id. at 119
    (noting that the cross-reference in (c)(2) could be
    - 17 -
    read to "refer[] to an alien who is taken into [immigration
    custody] 'when the alien is released'").
    In our view, the words "an alien described in paragraph
    (1)" comfortably support petitioners' reading.                    Consistent with
    the ordinary meaning of the word "described," § 1226(c)(2) refers
    to a "mental image, an impression, or an understanding of the
    nature and characteristics," see Webster's Third New International
    Dictionary 610 (2002), of the alien whom (c)(1) as a whole calls
    to mind.   And thus "an alien described in paragraph (1)" refers to
    an alien who has committed an enumerated offense and whom the
    Attorney General has taken into immigration custody "when . . .
    released" from criminal custody.           See also The American Heritage
    Dictionary of the English Language 476 (5th ed. 2011) (defining
    "describe" as "[t]o convey an idea or impression of" or "[t]o trace
    the form or outline of").
    No    rule   of   grammar   counsels       against    this   reading.
    Antecedents       to   cross-references    may     be    found    in   verbal   and
    adverbial phrases in prior paragraphs not just because (as our
    colleagues    suggest)     users   of    English    sometimes       use   language
    awkwardly.        Antecedents to cross-references may be found in such
    places because people also use language efficiently.11
    11According to linguists, "probably the most important thing
    to understand" about antecedents "is that [antecedents] are not
    the elements in the text but are those suggested by it, those

    One thus commits no offense against the English language
    by saying that the narrator "described in" Frost's famous poem is
    the one who "took the road less travelled," even though the
    narrator's first-person account of his past actions in the poem is
    not   cast    in   what   our   colleagues   would   consider   inherently
    descriptive terms.        And, in fact, Congress has itself relied on
    the "described in paragraph (1)" formulation to refer not just to
    the   inherently    descriptive    adjectival   portion    of   the   prior
    paragraph but to the adverbial portion, too.              See 28 U.S.C §
    1441(c)(1)-(2) (in referring to an "action described in paragraph
    (1)," Congress clearly intended to capture the trailing adverbial
    portion of paragraph (1), which states that the "entire action may
    be removed if the action would [otherwise] be removable").
    The petitioners' reading finds additional support in the
    fact that the text of the cross-reference does not expressly state,
    as one might have expected if Rojas were right, that the only part
    of § 1226(c)(1) that is relevant to (c)(2) is the part that

    denominates the (A)-(D) offenses.12                Rather than straightforwardly
    refer to "an alien described in subparagraphs (A)-(D)," Congress
    instead expressly referred to "an alien described in paragraph
    (1)," even though Congress singled out similar offenses to those
    set forth in (A)-(D) in the parallel detention mandate set forth
    elsewhere in the IIRIRA.              See IIRIRA § 303(b)(3), 110 Stat. 3009-
    587 ("The Attorney General may release the alien only if the alien
    is   an      alien   described    in    subparagraph        (A)(ii)   or   (A)(iii)."
    (emphasis added)).
    Nevertheless, we agree that, standing alone, the words
    "an alien described in paragraph (1)" could be read as Rojas reads
    them.        As a textual matter, the "described in" language in the
    cross-reference        could     be    read   to    refer    the   reader    only   to
    subparagraphs (A)-(D) of paragraph (1), as they plainly do describe
    the alien in (c)(1).           One could thus read this cross-reference as
    12
    Our colleagues argue that Rojas's reading is reinforced by
    the fact that the "when . . . released" clause is not aligned with
    subparagraphs (A)-(D), as if the indentation means to tell the
    reader of the cross-reference in § 1226(c)(2) where to look in
    (c)(1) for the antecedent. See infra at 72-73. But we do not see
    how that form of presentation has any helpful bearing on the
    meaning of (c)(2)'s cross-reference. The limits imposed by the
    unindented language, including the "when . . . released" clause,
    affect all aliens who come within the scope of (c)(1).         The
    predicate offenses identified in the indented subparagraphs, by
    contrast, serve as independent triggers. The alignment thus flows
    from the structure of (c)(1) without regard to the cross-reference
    in the follow-on paragraph and thus offers little support for
    Rojas's reading of that cross-reference.
    - 20 -
    directing the reader to identify the alien whom (c)(1) itself
    refers to in characteristically descriptive terms, rather than
    directing the reader to identify the alien whom (c)(1) as a whole
    calls to mind.13
    To determine if Congress chose between the two possible
    antecedents to the cross-reference in § 1226(c)(2), we thus must
    do what Rojas did: look beyond the words of the cross-reference.
    See Rojas, 23 I. & N. Dec. at 121-24 (reviewing the structure of
    the act in which § 1226 appears and its legislative history, as
    well as the predecessor provisions to § 1226).       And it makes
    particular sense to do so here, as there is good reason to question
    whether Congress would have intended to leave the precise issue
    unresolved.   To find that Congress did not intend to choose an
    antecedent, one would have to believe Congress was content to
    let the very executive branch officials that it did not trust to
    13  Our colleagues suggest that the Supreme Court has
    interpreted § 1226(c) as Rojas did, infra at 74-75, in 
    Demore, 538 U.S. at 513
    . But although the Supreme Court cited (c) as a whole
    in the first sentence of its opinion, the Court then went on to
    quote in that sentence the leading language of (c)(1) -- "[t]he
    Attorney General shall take into custody any alien who" -- without
    referencing (implicitly or otherwise) any of the language in
    (c)(2). Our colleagues do not -- and cannot -- argue that the
    "when . . . released" clause is irrelevant to even (c)(1). We
    thus do not see how the Court's failure to refer expressly to a
    clause that obviously applies to (c)(1) in its fly-by paraphrasing
    of (c)(1) could possibly be said to provide support for the
    government's view of the particular issue we must decide, which is
    the relationship between (c)(1) and (c)(2).          And that is
    particularly true as the relationship between the two paragraphs
    was not even at issue in Demore.

    make certain detention decisions determine the extent of that
    distrust     through     their       choice     between       the    two    possible
    antecedents.       See American Bar Ass'n v. F.T.C., 
    430 F.3d 457
    , 469
    (D.C. Cir. 2005) (noting that "the sort of ambiguity giving rise
    to   Chevron       deference    is     a    creature    not     of    definitional
    possibilities, but of statutory context" and declining to defer to
    an   agency's      interpretation      given    the    sort     of   ambiguity      at
    issue     (quotation   marks     and   citation    omitted)).         Accordingly,
    before we conclude that Congress did not speak to this issue, we
    need to consider the relevant words in context, as is required
    under Chevron step one.
    B.
    A key part of that context is the structure of the IIRIRA
    as a whole, as we are obliged to construe § 1226(c) in light of
    the whole act in which that provision appears.                 See Whitman v. Am.
    Trucking Ass'ns, 
    531 U.S. 457
    , 484 (2001).                The structure of that
    act, however, is hard to square with Rojas. And thus the structure
    of the IIRIRA supports the conclusion that Congress chose to refer
    to   an    alien   "described     in   paragraph       (1)"    rather      than   more
    specifically to an alien "described in subparagraphs (A)-(D)"
    because Congress intended to refer to an alien called to mind by
    the paragraph as a whole.
    We start first with the structure of § 1226, which is
    oddly misaligned unless we look beyond subparagraphs (A)-(D) of
    - 22 -
    (c)(1) to the "when . . . released" clause to identify the alien
    to whom (c)(2) refers.   Cf. 
    Whitman, 531 U.S. at 484-86
    (declining
    to defer to an agency's interpretation under Chevron where such
    interpretation was "so at odds with [the statute's] structure," in
    that it rendered certain parts of a carefully delimited exception
    to the agency's otherwise broad discretion "nugatory").         The
    misalignment arises because Rojas necessarily reads the cross-
    reference to de-link the "Custody" directive in § 1226(c)(1) from
    the bar to "Release" in (c)(2).
    Rojas has this effect because, for example, as the
    government has previously informed us, "there are a variety of
    offenses for which an alien may be . . . subject to mandatory
    detention under [§ 1226(c)(1)(A)], but that may never give rise to
    a formal charge, let alone an indictment, trial or conviction."
    See 
    Saysana, 590 F.3d at 14
    (quotation marks omitted) (restating
    the government's argument).14   In consequence, some aliens who fall
    within subparagraphs (A)-(D) will not be subject to (c)(1) because
    they will never have even been "released" from criminal custody as
    the "when . . . released" clause requires.    See Rojas, 23 I. & N.
    14For example, an alien may fall within § 1226(c)(1)(A) after
    receiving a summons and paying a fine for marijuana possession.
    See Immig. Law Profs. et al. Amicus Br. at 5-6.       In addition,
    aliens defined in § 1226(c)(1)(D) are inadmissible or deportable
    solely for having engaged in certain terrorist conduct, and so
    criminal custody is not a necessary precondition to qualifying as
    a (D)-type alien.
    - 23 -
    Dec. at 122.15    According to Rojas, however, such aliens -- if
    taken into custody pursuant to § 1226(a) -- would still be subject
    to the bar to bonded release that (c)(2) establishes.
    Rojas necessarily would apply the bar to bonded release
    to such aliens because Rojas makes an alien's "release" from
    criminal custody irrelevant to the application of § 1226(c)(2).
    After all, it is the "when . . . released" clause and not
    subparagraphs (A)-(D) that ensures that an alien taken into custody
    pursuant to (c)(1) is an alien who has been "released" from
    criminal custody.      Thus, Rojas incongruously (and without even
    acknowledging    the   incongruity)    requires       one   to   believe   that
    Congress was so concerned about certain aliens who had never been
    in   criminal   custody,   as   the   "when   .   .    .    released"   clause
    contemplates, being out and about that it directed the Attorney
    General to hold them without bond even though Congress left her
    15Under any interpretation of "released," see H.R. Rep. No.
    101-681(I), § 1503, at 148 (1990), reprinted in 1990 U.S.C.C.A.N.

    1990 WL 188857
    (stating that the trailing language in
    § 1226(c)(1) was intended to clarify that the Attorney General
    must "incarcerate aggravated felons upon release from confinement,
    regardless of whether such release involves parole, probation, or
    other forms of supervision." (emphasis added)); Lora,

    complete discretion to decide not to take them into immigration
    custody at all.16
    Petitioners'   reading    avoids   this   oddly   half-hearted
    understanding of the detention mandate.           Petitioners read the
    release-from-criminal-custody       constraint   that   appears   outside
    subparagraphs (A)-(D) and in the "when . . . released" clause to
    limit both the "Custody" and "Release" aspects of the detention
    mandate.   Under this more natural reading, § 1226 as a whole
    coheres quite well.   Pursuant to § 1226(a), the Attorney General
    would have the discretion to release on bond those aliens she had
    the discretion not to take into custody.             And, pursuant to §
    1226(c), the Attorney General would be mandated to keep in custody
    16 Tellingly, there is no indication in the record or
    legislative history to the IIRIRA that Congress was any more
    worried about the release by immigration authorities of criminal
    aliens already in immigration custody than about the failure of
    immigration authorities to take criminal aliens into custody in
    the first place. And thus we do not see a basis for concluding
    that a Congress concerned about "[u]ndetained aliens," S. Rep. No.
    104-48 (1995), 
    1995 WL 170285
    , at *2, would be inclined to place
    a release-from-criminal-custody constraint on the discretion to
    take aliens into immigration custody but not on the discretion to
    release aliens from such custody.      The puzzle, then, is why
    Congress would have wanted to express its unhappiness with both
    forms of executive discretion in the partial way Rojas favors.
    Notably, such different treatment would apply not only to the one
    type of alien who has never been released from criminal custody
    that our colleagues choose to mention, see infra at 90, but it
    would also implicate myriad other types of aliens that the
    government itself has consistently identified as falling within
    subparagraphs (A)-(D) but not within the (c)(1) custody directive
    more broadly. See, e.g., 
    Saysana, 590 F.3d at 14
    .
    - 25 -
    only those she was mandated to take into custody.17         See 
    Saysana, 590 F.3d at 9
    , 13-16 (analyzing the meaning of the "when . . .
    released" clause and its trailing language in (c)(1) in order to
    determine whether an alien was properly held without bond under
    (c)(2)).   In this way, Congress would have crafted a detention
    mandate that, from start to finish, covers the same class of aliens
    (whatever the word "when" might mean) that it had identified as a
    cause for concern.18
    Two other parts of the IIRIRA lend further support to
    petitioners'   reading   of   the   cross-reference,   in    which   the
    "when . . . released" clause in (c)(1) applies as a constraint
    17 Our colleagues note that the description in § 1226(c)(2)
    of when aliens subject to that provision may qualify for release
    from   immigration   custody   --  when   necessary   for   witness
    protection -- does not refer expressly to the "when . . . released"
    clause. See infra at 74. But (c)(2) also does not expressly refer
    to subparagraphs (A)-(D), yet our colleagues would not dispute
    that a person with no such predicate offense could not be subject
    to (c)(2). We thus do not believe this exception clarifies the
    precise issue at hand in any respect.
    18 In describing the "mandatory detention provision" (i.e.,
    § 1226(c)), the panel in Saysana concluded that "the 'when
    released' language serves th[e] . . . limited but focused purpose
    of preventing the return to the community of those released in
    connection with the enumerated offenses [in subparagraphs (A)-
    (D)] . . . 
    ." 590 F.3d at 17
    (emphasis added).     Saysana thus
    viewed the "when . . . released" clause as limiting (c) as a whole,
    including the piece of (c) that "prevents the return to the
    community" (i.e., prohibits the bonded release) of certain aliens.
    See also Matter of García-Arreola, 25 I. & N. Dec. 267, 270-71 &
    n.4 (BIA 2010) (concluding that Saysana held that (c)(2) refers to
    and incorporates the "when . . . released" clause as a constraint
    and thereby recognizing the conflict between Saysana and Rojas).
    - 26 -
    across the whole of (c).        These parts of the IIRIRA are set forth
    in the Transition Period Custody Rules (TPCR).             These rules apply
    instead of § 1226(c) for a one- or two-year transition period, but
    only    if   they   are    invoked   by   the   Attorney   General.   IIRIRA
    § 303(b)(2), Pub. L. No. 104-208, 110 Stat. at 3009-586.
    The first instructive part lies in the TPCR's parallel
    detention mandate.         The TPCR's mandate shares the same structure
    as § 1226(c).19           And, notably, like § 1226(c), the predicate
    19The TPCR, enacted in IIRIRA § 303(b)(3), Pub. L. No. 104-
    208, 110 Stat. at 3009-587, provides in part:
    (A) IN GENERAL. -- During the period in which this
    paragraph is in effect pursuant to paragraph (2), the Attorney
    General shall take into custody any alien who --
    (i) has been convicted of an aggravated felony . . . ,
    (ii) is inadmissible by reason of . . . ,
    (iii) is deportable by reason of having committed any
    offense covered in . . . , or
    (iv) is inadmissible under . . . ,
    when the alien is released, without regard to whether the
    alien is released on parole, supervised release, or
    probation, and without regard to whether the alien may be
    arrested or imprisoned again for the same offense.
    (B) RELEASE. -- The Attorney General may release the alien
    only if the alien is an alien described in subparagraph
    (A)(ii) or (A)(iii) and--
    (i) the alien was lawfully admitted to the United States
    and satisfies the Attorney General that the alien will
    not pose a danger to the safety of other persons or of
    property and is likely to appear for any scheduled
    proceeding, or
    (ii) the alien was not lawfully admitted to the United
    States, cannot be removed because the designated country
    of removal will not accept the alien, and satisfies the
    Attorney General that the alien will not pose a danger
    to the safety of other persons or of property and is
    likely to appear for any scheduled proceeding.
    - 27 -
    offenses that trigger the custody directive in the TPCR do not
    require an alien to have been "released" from criminal custody.
    See Matter of Garvin-Noble, 21 I. & N. Dec. 672, 680-81 (BIA 1997).
    The TPCR's mandate thus presents the same interpretive question
    that § 1226(c) presents as to whether the "when . . . released"
    clause -- and thus its release-from-criminal-custody constraint -
    - in that mandate's custody directive limits that mandate's follow-
    on bar to bonded release.       And because this mandate presents the
    same interpretive question, it also presents the same potential
    structural misalignment.20
    Tellingly,   the   TPCR   presents   its   custody   directive
    (including its "when . . . released" clause) under the heading "In
    General" and the bar to bonded release under the subsequent
    heading,   "Release."    This    presentation    indicates      that   the
    "when . . . released" clause constrains both the custody directive
    and the bar to bonded release, such that the bar applies to the
    very people encompassed by the "General" directive, rather than to
    some people who were not encompassed by that directive at all
    because they were never "released" from criminal custody.
    20The two paragraphs in the transition rules are linked by a
    cross-reference ("the alien") that differs from the one our
    colleagues   mistakenly  assign   such   weight   in   construing
    § 1226(c)(2) and that is, as a purely textual matter, also not
    clear.
    - 28 -
    The second instructive part of the IIRIRA lies in section
    303(b)(2), Pub. L. No. 104-208, 110 Stat. at 3009-586.       This TPCR
    provision mediates the shift from the transition rules to the
    permanent regime.   The provision clearly provides that § 1226(c)
    as a whole -- both with respect to its custody directive and its
    bar to bonded release -- applies only to aliens "released after"
    the TPCR expires.    And the BIA has rightly read this "released
    after" clause to mean that an alien must have been "released" from
    criminal custody to be subject to § 1226(c) going forward.        See In
    re Adeniji, 22 I. & N. Dec. 1102, 1108-11 (BIA 1999).    This clause
    thus ensures that a release-from-criminal-custody constraint does
    now limit the scope of both (c)(1) and (c)(2).
    If we applied Rojas's analysis of (c)(2) to the TPCR's
    equivalent to (c)(2), however, no such "released" constraint would
    limit the scope of that portion of the TCPR's detention mandate
    because the "when . . . released" clause in its custody directive
    would not apply to the mandate as a whole. Under Rojas, therefore,
    the "released after" clause would -- in this key respect -- make
    the permanent mandate's bar to bonded release less sweeping than
    the supposedly more flexible TPCR mandate's bar had been, even
    though   Congress   clearly   intended   the   latter   to   be    less
    - 29 -
    encompassing.21      No such anomalous narrowing of the detention
    mandate    would   occur    upon    the   expiration   of    the    TPCR   if,   by
    contrast, the "when . . . released" clause limits the bar to bonded
    release that appears in both the transition and the permanent
    rules.22
    For these reasons, the structure of the IIRIRA as a whole
    strongly    indicates      that    Congress   did   intend    for    the   cross-
    reference in § 1226(c)(2) to reach beyond subparagraphs (A)-(D) to
    the "when . . . released" clause and thus to refer to an alien
    taken into custody pursuant to the duty imposed by (c)(1) as a
    whole.23   And thus the IIRIRA's structure indicates that Congress
    21 See 142 Cong. Rec. S11838-01, 
    1996 WL 553814
    (daily ed.
    Sept. 30, 1996) (statement of Sen. Hatch) (explaining that one of
    the IIRIRA's managers and conferees agreed to the TPCR because of
    the INS's pleas of insufficient resources to comply with the
    AEDPA); Garvin-Noble, 21 I. & N. Dec. at 675 (same).
    22 Our colleagues try to downplay this anomaly by emphasizing
    the carve-outs in the TPCR's bar to bonded release. See infra at
    88-89.      But these carve-outs are limited ones.          IIRIRA
    § 303(b)(3)(B), Pub. L. No. 104-208, 110 Stat. at 3009-587. And
    we think it unlikely that Congress would have intended for only
    the detention mandate in the transition regime -- and not the
    detention mandate in the permanent regime -- to apply to some
    aliens in such classes of potentially dangerous criminal aliens as
    unlawfully admitted aliens with a § 1226(c)(1)(A) predicate and
    aliens with a § 1226(c)(1)(D) predicate. It is especially unlikely
    that Congress would have intended the TPCR, but not § 1226(c), to
    operate without a release-from-criminal-custody constraint on its
    detention mandate when the preceding detention mandate did embody
    such a constraint. See AEDPA, § 440(c), Pub. L. No. 104-132, 110
    Stat. 1214, 1277; see Grodzki v. Reno, 
    950 F. Supp. 339
    , 342 (N.D.
    Ga. 1996).
    23   The "released after" clause would minimize the strange
    disjuncture between § 1226(c)(1) and (c)(2) that Rojas unavoidably
    - 30 -
    referred to paragraph (1) rather than more specifically to the
    subparagraphs within in it because Congress intended to link the
    "Custody" and "Release" aspects of the detention mandate so that
    they would work together. Before we conclude that Congress clearly
    chose the broader antecedent to "an alien described in paragraph
    (1)," however, we must still "exhaust the traditional tools of
    statutory construction."   See Sierra Club v. EPA, 
    551 F.3d 1019
    ,
    1027 (D.C. Cir. 2008).     And so we now turn to the legislative
    history.
    C.
    The legislative history confirms that Congress intended
    the cross-reference in § 1226(c)(2) to refer to an alien taken
    into custody pursuant to the duty imposed by (c)(1) as a whole
    creates, but we presume the coherence of the permanent detention
    mandate was not intended to depend on the triggering of an
    ancillary and potentially never operative clause in the TPCR.
    
    Whitman, 531 U.S. at 468
    . Regardless, the "released after" clause
    would do nothing to avoid the anomaly of the permanent mandate
    being less sweeping in a key respect than the transition mandate
    had been.
    Our colleagues, but not the government or Rojas itself,
    contend that the canon against surplusage supports Rojas's reading
    of the cross-reference in § 1226(c)(2) because otherwise
    "when . . . released" would be duplicative of "released after."
    See infra at 75-76. But to the extent this argument has any force,
    it has it only if "when" has a time-limited meaning.            The
    surplusage concern thus provides no basis for concluding that Rojas
    is right to treat the "when . . . released" clause as a whole as
    irrelevant to (c)(2). As a result, we consider this surplusage
    argument when we turn to the issue of what "when" means -- an issue
    on which we owe the BIA no deference and which we must confront
    only if the "when . . . released" clause does apply to all of (c).
    - 31 -
    rather than only to an alien described in subparagraphs (A)-(D).
    And thus the legislative history helps to make clear that the
    "when . . . released" clause -- and whatever limitations it
    imposes -- applies across the whole of (c).                     This conclusion
    follows from the legislative history directly tied to the IIRIRA
    and from the many precursors to § 1226(c).                The text and history
    of those precursors show that Congress intended for those versions
    of    the    detention    mandate     to     operate     in   just    the     linked
    manner that Rojas rejects in construing (c), and the evidence also
    indicates that Congress did not mean to alter this aspect of the
    longstanding scheme in passing the IIRIRA.                Milner v. Department
    of the Navy, 
    562 U.S. 562
    , 572 (2011) ("Those of us who make use
    of    legislative       history     believe       that    clear      evidence    of
    congressional      intent    may    illuminate      ambiguous        text.");    see
    also Goldings v. Winn, 
    383 F.3d 17
    , 21 (1st Cir. 2004) ("[I]f the
    statute's legislative history reveals an unequivocal answer as to
    the         statute's      meaning,          we     do        not      look       to
    the [agency's] interpretation . . . .").
    1.
    The title to § 1226(c) -- encompassing both (c)(1)'s
    "Custody" directive and (c)(2)'s "Release" bar -- is "Detention of
    Criminal Aliens."        The conference report to the IIRIRA follows the
    language of that overarching title in describing in unqualified
    terms the "subsection" as providing that the Attorney General "must
    - 32 -
    detain"     certain     aliens.         The    report    then     sets     forth   one
    qualification to that requirement in the next sentence and another
    qualification     in     the    third     sentence,       stating    that     "[t]his
    detention mandate applies whenever such an alien is released from
    imprisonment,         regardless     of        the      circumstances       of     the
    release."       H.R.     Conf.     Rep.       No.    104-828     (1996),    
    1996 WL 563320
    , at *210-11.        And finally, the report states that "[t]his
    subsection also provides" for the "release[]" of aliens "from the
    Attorney General's custody" in one limited circumstance.                      See 
    id. In keeping
    with the title to § 1226(c), we thus understand the use
    of the phrase "[t]his detention mandate" to refer to a start-to-
    finish detention regime that is limited across-the-board by the
    "when . . . released" clause.             See Rojas, 23 I. & N. Dec. at 119,
    122-23    (describing     the     "mandatory         detention    aspects     of   the
    statute" as arising from both the bar to bonded release and the
    custody directive).        After all, the report expressly attributes
    the mandate to the "subsection" it describes rather than to only
    part of it.
    But even if, as our colleagues contend, the report's
    reference to "[t]his detention mandate" is only to the differently
    worded and more limited duty to "take into custody" certain aliens
    set forth only in § 1226(c)(1), see infra at 77-78, the report
    would then merely restate the question that we must decide: whether
    Congress intended for the bar to bonded release set forth in (c)(2)
    - 33 -
    to incorporate the conditions that plainly limit the application
    of the custody directive in (c)(1).24           If so, the remaining
    legislative   history    that   actually   concerns   the   relationship
    between the custody and release aspects of the detention mandate
    convinces us that Congress clearly did so intend, when this history
    is read against the strong structural reasons to conclude that
    Congress chose to refer in (c)(2) to "paragraph (1)" rather than
    subparagraphs (A)-(D) in order to encompass the same aliens under
    both (c)(1) and (c)(2).
    Just prior to conference, a leading Senate sponsor of
    the IIRIRA described the bill as "ensur[ing] that aliens who commit
    serious crimes are detained upon their release from prison until
    they can be deported . . . ."     142 Cong. Rec. S10572-01 (daily ed.
    Sept. 16, 1996), 
    1996 WL 522794
    (statement of Sen. Simpson)
    (emphasis added).       And it should be no surprise that Senator
    24 Our colleagues' reading of the fourth sentence of the
    report, see infra at 77-78, takes "the Attorney General's custody"
    referenced in that sentence to be any custody, even if effected as
    a matter of discretion under § 1226(a), rather than to be the
    mandatory custody of the Attorney General under § 1226(c) that --
    on our colleagues' reading of the report -- the preceding sentences
    had necessarily just referenced.      And our colleagues read the
    reference to "such an alien" in that sentence to be a reference
    only to an alien who has committed an (A)-(D) offense rather than
    to an alien who was taken into custody pursuant to the duty imposed
    by (c)(1) as a whole.     See 
    id. But the
    text does not resolve
    whether our colleagues are right to read these words this way, as
    these words on their own do not tell us whether the report treats
    the "when . . . released" clause as if it were incorporated as a
    limitation on the bar to bonded release.
    - 34 -
    Simpson described the bill this way.            Congress stated in a key
    report right before conference that the new measure was intended
    to "restate[]" the provisions of the old statute "regarding the
    detention of an alien convicted of an aggravated felony . . . ."
    See H.R. Rep. 104-469(I) (1996), 
    1996 WL 168955
    , at *230.              And, as
    we next explain, each prior version of the detention mandate
    (including    the   immediate      precursor   to   the   IIRIRA)   similarly
    treated the two analogous directives to the ones that subsection
    (c) contains as operating in tandem.
    2.
    The text and legislative history to the precursors to
    § 1226(c) clearly show that Congress intended to link the custody
    directive and the bar to bonded release in these prior detention
    mandates   in   just   the   way    that   Rojas    rejects   in    construing
    § 1226(c).    And interpreters of those precursors –- including both
    the BIA and the district courts –- so read them.
    We start with the 1988 mandatory detention statute,
    which provided: "The Attorney General shall take into custody any
    alien convicted of an aggravated felony upon completion of the
    alien's sentence for such conviction.          Notwithstanding subsection
    (a) [the then-equivalent of § 1226(a)], the Attorney General shall
    not release such felon from custody." Anti-Drug Abuse Act of 1988,
    § 7343(a), Pub. L. No. 100-690, 102 Stat. 4470.            The text is most
    naturally read as limiting the bar to bonded release to the
    - 35 -
    "felons" whom the Attorney General was required to "take into
    custody."   And not long after its enactment, the BIA read the
    provision   just   that   way,   by   treating   the    "upon   completion"
    clause (the then-equivalent of the "when . . . released" clause) in
    the 1988 mandate's custody directive as if it conditioned that
    mandate's "such felon" clause (the then-equivalent of "an alien
    described   in     paragraph     (1)")   in   the      follow-on   bar   to
    bonded release from immigration custody.         Matter of Eden, 20 I. &
    N. Dec. 209, 211 (BIA 1990).25
    25 The BIA's decision in Eden, as our colleagues point out,
    did not involve the particular timing element involved in this
    case. But that is no matter as Eden is directly on point as to
    the precise issue for which the government seeks Chevron
    deference -- that is, the relationship between the "custody" and
    "release" aspects of the present detention mandate. Our colleagues
    contend otherwise as follows. Our colleagues suggest that even if
    the BIA in Eden had reached the same result by concluding, instead,
    that once an aggravated felon was in immigration custody he could
    not then be released on bond (regardless of whether he had ever
    been released from criminal custody), the BIA still would have had
    reason to consider the meaning of the "upon completion" clause.
    And that is because, our colleagues contend, the BIA would have
    had an interest in clarifying whether the Attorney General had the
    authority to place an alien in immigration custody at all, even
    discretionarily, while that alien was still serving his criminal
    sentence. See infra at 93-94. But the BIA had no need to clarify
    the meaning of the "upon completion" clause for that distinct
    purpose. And that is because, as the BIA in Eden acknowledged, an
    alien could have been taken into immigration custody under the
    discretionary detention authority conferred by then-equivalent to
    § 1226(a).     In fact, the immigration judge in Eden granted
    discretionary bond to the alien in that case under the then-
    equivalent of § 1226(a), which occasioned the appeal to the BIA by
    the executive. See Eden, 20 I. & N. Dec. at 210, 212 (noting that
    the immigration judge had concluded that the alien "had been
    properly detained under [the then-equivalent of § 1226(a)]" and
    - 36 -
    The 1990 amendments to the 1988 statute then codified
    Eden, which was decided months earlier, and the House report to
    the amendments espoused that same view of the relationship between
    the two clauses.    That report characterized "current law" (that
    is, the detention mandate set forth in the 1988 statute) as
    "requir[ing] [the government] to incarcerate alien aggravated
    felons without bond immediately upon completion of the alien's
    criminal 'sentence.'"        H.R. Rep. No. 101-681(I), § 1503, at 148
    (1990) (emphasis added); cf. United States v. Bd. of Comm'rs of
    Sheffield, Ala., 
    435 U.S. 110
    , 129-35 (1978).
    Moreover, in codifying Eden, Congress modified the then-
    equivalent of § 1226(c)(1) in order to clarify the scope of the
    then-equivalent of (c)(2).       Congress did so by making clear that
    aliens were "released" from criminal custody and thus could be
    held   without   bond   at    the   moment   they   were   released   from
    incarceration, even though they might still be on parole or
    supervised release.26    In revising the "upon completion" clause,
    Congress   necessarily       treated   the   then-equivalent     of   the
    framing the question on appeal in terms of whether "authority to
    detain [an alien while he was on parole] pursuant to [the then-
    equivalent of § 1226(c)] . . . exist[ed]" (emphasis added)).
    26 Congress replaced the "upon completion" clause with "upon
    release of the alien (regardless of whether or not such release is
    on parole, supervised release, or probation, and regardless of the
    possibility of rearrest or further confinement in respect of the
    same offense)." Immigration Act of 1990, § 504(a), Pub. L. No.
    101-649, 104 Stat. 4978, 5049-50; H.R. Rep. No. 101-681(I), § 1503,
    at 148 (1990).
    - 37 -
    "when . . . released" clause and its trailing language as limiting
    the follow-on bar to bonded release.               Otherwise, Congress would
    have had no need to tinker with that language at all in light of
    the discretion to place aliens in immigration custody that the
    Attorney General otherwise had.            And, by passing the amendments,
    Congress   necessarily        retained    (albeit     in    revised     form)   that
    limitation on the operation of both the custody directive and the
    bar to bonded release.27
    Finally,    in    1996,     not   long        before   the    IIRIRA's
    enactment,    Congress    further        amended    the     mandatory     detention
    statute while again retaining the same structure, which again
    naturally reads as if those barred from release are those that
    must be picked up.      See AEDPA, § 440(c), Pub. L. No. 104-132, 110
    27We do not find our colleagues' contrary reading of the 1990
    House report -- in which Congress was supposedly responding to a
    concern that the "upon completion" clause might be read to
    displace, as to aliens on parole, the Attorney General's general
    and unqualified grant of discretionary authority to take aliens
    into immigration custody, see infra at 94-95 -- persuasive.
    Congress was responding to Eden and the immigration judge in that
    case did clearly conclude that the Attorney General had the
    authority to place an alien on parole in immigration custody under
    the then-equivalent of § 1226(a). See Eden, 20 I. & N. Dec. at
    210. In offering a contrary reading of the report, our colleagues
    ignore the introductory sentence of the relevant portion of the
    report, which we read to supply the context for the sentences that
    follow: "Current law . . . requires INS to incarcerate alien
    aggravated felons without bond immediately upon completion of the
    alien's criminal 'sentence.'" H.R. Rep. No. 101-681(I), § 1503,
    at 148 (1990) (emphasis added). We therefore read the sentences
    that follow to be referring to the authority to incarcerate aliens
    without bond under the mandatory detention provision. See 
    id. - 38
    -
    Stat.        1214,   1277   (retaining   "upon   release"/"such   felon"
    structure). And prior to the passage of § 1226(c), district courts
    not surprisingly treated the retained "upon release" clause as if
    it conditioned the retained "such felon" clause, just as the BIA
    and Congress itself had treated the analogous clauses in prior
    detention mandates.28
    We generally "assume that Congress is aware of existing
    law when it passes legislation," see Miles v. Apex,

    prevailing interpretation of the relationship between the custody
    28
    District courts held that the AEDPA did not apply
    retroactively to aliens who had been convicted and released from
    incarceration before its enactment in part because the "upon
    release" clause implicitly limited the application of the
    detention mandate, including the aspect of the mandate governing
    bonded release, to people taken into custody after the AEDPA's
    passage. See, e.g., DeMelo v. Cobb, 
    936 F. Supp. 30
    , 36 (D. Mass.
    1996), vacated as moot after the IIRIRA's passage, 
    108 F.3d 328
    (1st Cir. 1997) (per curiam) (concluding "that the language 'upon
    release of the alien from incarceration' implies a time of release
    after the effective date of the Act" and thus makes the detention
    mandate as a whole prospective in application); Villagomez v.

    1996 WL 622451

    31, 1996) (unpublished) (stating that the AEDPA's detention
    mandate as a whole cannot apply to aliens convicted and released
    before its enactment because of the "straightforward" "upon
    release" language); Montero v. Cobb,

    directive and the bar to bonded release to be a linked one.              After
    all, courts were consistently interpreting that relationship post-
    AEDPA in the same way Congress and the BIA had interpreted that
    relationship in the similarly worded clauses pre-AEDPA.29                  And
    while        Congress   broadened   the   cross-reference   in   the   present
    29
    Our colleagues, see infra at 91-92, following Rojas's lead,
    see Rojas, 23 I. & N. Dec. at 122-24, find instructive the 1991
    revision to an exception to the bar to bonded release contained in
    the 1990 detention mandate. See Immigration Act of 1990, § 504(a),
    Pub. L. No. 101-649, 104 Stat. 4978, 5049-50; Miscellaneous and
    Technical Immigration and Naturalization Amendments of 1991,
    § 306(a)(4), Pub. L. No. 102-232, 105 Stat. 1733, 1751.      Rojas
    contends that the text of the exception to the bar to bonded
    release (set forth in the revised version of paragraph (B)) shows
    that the "upon release" constraint in the then-effective detention
    mandate (set forth in paragraph (A)) limited neither the class of
    lawfully admitted aliens referenced in (B)'s exception nor "such
    felon[s]" referenced in (A)'s bar to bonded release. 23 I. & N.
    Dec. at 124. But as the legislative history just described shows,
    in crafting that 1990 detention mandate, Congress plainly did
    intend for the "upon release" requirement to modify the "such
    felon[s]" who were subject to (A)'s bar to bonded release.      We
    thus see no basis for concluding that Congress suddenly intended
    to alter the relationship between the "upon release" and "such
    felon" clauses in paragraph (A) in 1991 by way of a technical
    amendment to paragraph (B) that does not appear to have been made
    for any such consequential purpose.     See Cong. Research Serv.,
    Summaries for Miscellaneous and Technical Immigration and
    Naturalization Amendments of 1991 (H.R. 3049, 102nd Cong.),
    https://www.govtrack.us/congress/bills/102/hr3049/summary
    (summarizing the 1991 revision as applying the exception in (B) to
    all "lawfully admitted aliens" as opposed to just aliens "lawfully
    admitted for permanent residence").      Consistent with a modest
    understanding of the 1991 technical revision's import, we read
    (B) -- by virtue of the fact that (A) is "subject to paragraph
    (B)" -- to refer merely to a subset of "such felon[s]" in (A),
    which is to say felons taken into immigration custody "upon
    release." In any event, we question the salience of paragraph (B)
    for present purposes given that it had been deleted by the AEDPA
    by the time Congress got around to enacting the IIRIRA, see AEDPA
    § 440(c), 110 Stat. at 1277.

    detention mandate to account for the fact that not all aliens
    subject to the present mandate qualify as "felons," we do not think
    Congress thereby intended to alter fundamentally the relationship
    between the custody directive and the bar to bonded release.                           In
    fact, the evidence is to the contrary.                   See H.R. Rep. 104-469(I)
    (1996), 
    1996 WL 168955
    , at *230 (stating that § 1226(c) was
    intended     to    "restate[]"      the     provisions         of    the    immediately
    preceding detention mandate codified in the AEDPA).
    3.
    In    countering       the     substantial        evidence       from     the
    legislative history that points against Rojas, the government and
    our colleagues give great weight to an April 1995 report from the
    Senate Committee on Governmental Affairs.                  See S. Rep. No. 104-48
    (1995), 
    1995 WL 170285
    .          The Supreme Court relied on that report
    in Demore v. Kim, 
    538 U.S. 510
    , 518-22 (2003), to explain why
    Congress could have had a reason for mandating the detention
    without    bond    of    criminal    aliens      in    order    to   respond     to    the
    contention        that    such   mandatory            detention      was      inherently
    arbitrary.         In    addressing       that   constitutional            challenge   to
    Congress's power to enact a detention mandate of any scope, the
    Supreme Court did not purport to enlist that report to describe
    the class of aliens subject to the mandate § 1226(c) actually
    imposed.    And for good reason.
    - 41 -
    That     1995   report    was    not   linked    to   any   particular
    bill.       And that report predates not only § 1226(c) but also the
    immediate precursor to (c), which used the same "upon"/"such felon"
    language that tracked the 1988 mandate and its revisions that we
    have just described.            The 1995 Senate report cannot offer any
    support, therefore, for the suggestion that the present detention
    mandate must have de-linked the custody directive and bar to bonded
    release that had been linked in those prior versions.
    And, in fact, the report does not speak to that issue at
    all.    To be sure, that report does show that its authors were
    "concerned      with    detaining      and    removing   all   criminal    aliens,"
    Rojas, 23 I. & N. Dec. at 122 (emphasis in original); see also
    Sylvain v. Attorney Gen. of U.S., 
    714 F.3d 150
    , 160 (3d Cir. 2013).
    But    in    stating     that   general       concern,   the    report    does   not
    demonstrate that Congress intended to paint with the broad brush
    the government suggests that it used in enacting § 1226(c)(2).
    See 
    Saysana, 590 F.3d at 16-18
    ("The mandatory detention provision
    does not reflect a general policy in favor of detention . . . .").
    The report does also suggest a variety of ways to address
    the concern that "criminal aliens" (i.e., aliens with deportable
    offenses) do not show up to removal proceedings. These suggestions
    range from increasing detention bed space to accommodate enhanced
    detention efforts generally, to expediting the removal process so
    that final adjudication occurs while an alien is still in criminal
    - 42 -
    custody, to expanding the role of mandatory detention (§ 1226(c))
    in relation to discretionary detention (§ 1226(a)) by subjecting
    all criminal aliens to (c).        See S. Rep. No. 104-48 (1995), 
    1995 WL 170285
    ,   at   *3-4,   *21,   *23,   *31-32.   The   report   nowhere
    indicates, however, that Congress wanted to expand the role of
    mandatory detention haphazardly by de-linking (c)(1) and (c)(2),
    such that the bar to bonded release would apply to persons who
    were not even subject to the custody directive at all because they
    had never been in the criminal custody from which they were then
    "released" as (c)(1) contemplates.         See generally id.30
    30
    Our colleagues find support for Rojas in Congress's evident
    intent to make it more difficult for certain criminal aliens to
    obtain relief from a final order of removal, see infra at 82-84,
    on the apparent assumption that the risk of flight is greater for
    aliens who are more certain to be removed (and this class is an
    especially dangerous one). But the petitioners have not yet faced
    a definitive adverse judgment in their removal proceedings and so
    may not in fact be removed. Moreover, aliens taken into custody
    under § 1226(c) may also have a basis for discretionary relief in
    the form of cancellation of removal, see Lora, 
    2015 WL 6499951
    , at
    *3, *12, or some other form of relief, such as a U Visa (a type of
    visa set aside for victims of certain crimes). We thus see no
    justification for the inference that Congress, in making it harder
    to get relief from a final removal order, must have intended to
    deny bond to those who might not be ordered removed at all. In
    fact, as Congress surely knows, an alien's inability to get bonded
    release can limit the alien's capacity to obtain legal
    representation or otherwise obtain relief from removal, see Robert
    A. Katzmann, The Legal Profession and the Unmet Needs of the
    Immigrant Poor, 21 Geo. J. Legal Ethics 3, 10 (2008); Moncrieffe
    v. Holder, 
    133 S. Ct. 1678
    , 1690 (2013), making the impact of
    mandatory detention prior to a final removal order especially harsh
    in cases where avenues for relief following such order have been
    curtailed.
    - 43 -
    4.
    In sum, Rojas offers only one reason for concluding that
    these petitioners may not be given a bond hearing and that reason
    has nothing to with what the word "when" means.         On Rojas's view,
    § 1226(c)(2) applies to any alien who has committed an (A)-(D)
    offense, regardless of whether the alien was ever in and "released"
    from criminal custody as (c)(1) requires, let alone "when" the
    alien was released from it.      And that is because Rojas holds that
    the "when . . . released" clause as a whole is irrelevant to
    (c)(2).    But when we consider the text of (c)(2) in light of the
    structure of the IIRIRA as a whole and the legislative history, we
    do not believe that Rojas offers a tenable construction of the
    detention mandate.
    After    applying    the   traditional    tools   of    statutory
    interpretation, we conclude that Congress did clearly speak to the
    precise issue Rojas addressed regarding the relevance of the
    "when . . . released" clause to the bar to bonded release in
    § 1226(c)(2).      And Congress clearly addressed it in the opposite
    way from Rojas.     That is, Congress clearly intended for the cross-
    reference in (c)(2) to refer to aliens who have committed (A)-(D)
    offenses   and    who   have   been   taken   into   immigration    custody
    "when . . . released" from criminal custody, in accordance with
    the Attorney General's duty under (c)(1).
    - 44 -
    In concluding that Rojas does warrant deference, our
    colleagues repeatedly emphasize that it is reasonable to conclude
    that the timeliness of an alien's immigration custody is not
    determinative of whether the detention mandate applies.                        But it is
    important not to confuse the outcome that results from Rojas's
    interpretation of the mandate's scope with the interpretation
    itself.
    For while it is true that Rojas's conclusion that the
    "when    .   .   .    released"     clause    as    a     whole    is    irrelevant     to
    §   1226(c)(2)        necessarily    makes    timeliness          irrelevant     to   the
    operation of (c)(2), Chevron is clear that it is the agency's
    interpretation of the statute and not the outcome that follows
    from that interpretation that deserves our deference.                         See Lin v.
    U.S.    Dep't    of    Justice,     
    416 F.3d 184
    ,    191-92       (2d   Cir.   2005)
    (declining to defer to BIA's summary affirmance of an immigration
    judge decision because summary affirmance indicates approval of
    only "the result reached in the decision" rather than "all of the
    reasoning of that decision" and thus does not contain "the sort of
    authoritative and considered statutory construction that Chevron
    deference was designed to honor").                 And that must be the case, as
    the reason we defer to agency interpretations is precisely because
    we are supposed to give weight to their reasoned judgment.
    For Chevron purposes, therefore, the contention that the
    legislative history or the structure of the IIRIRA does not compel
    - 45 -
    the timing-based outcome that the petitioners favor amounts to a
    non sequitur.      What matters is that Rojas implausibly ascribes an
    intention to Congress to place greater limits on the Attorney
    General's discretion to take aliens into custody in the first place
    than on the Attorney General's discretion to release them once
    they are in custody.     And so, having determined under Chevron step
    one that Rojas's interpretation of the relationship between (c)(1)
    and (c)(2) conflicts with Congress's evident intent and thus does
    not merit deference, we now turn to the question that remains: the
    meaning of (c)(1)'s "when . . . released" clause.
    III.
    In taking up this issue, we confront the question that
    Rojas never reaches: does "when" impose a time limit for taking an
    alien into custody pursuant to (c)(1) that renders (c)(2)'s bar to
    bonded   release    inapplicable   to   these   petitioners      due   to   the
    remoteness of their release from criminal custody?            See 
    Sylvain, 714 F.3d at 157
    n.9 (stating that Rojas "did not explicitly
    interpret" the word "when").
    The government argues that the word "when" imposes no
    such time limit, either because "when" means "if" or "any time
    after" or because Congress at most used the word "when" to trigger
    a duty to act promptly that persists indefinitely.                 The BIA,
    however,   has   never   adopted   either   view,   and   such    litigating
    - 46 -
    positions are not entitled to Chevron deference.31            See United
    States v. Mead Corp., 
    533 U.S. 218
    , 231 (2001).             We thus must
    decide the clause's meaning on our own.        See Santana v. Holder,
    
    731 F.3d 50
    , 53 (1st Cir. 2013).
    To do so, we first consider whether the word "when" as
    used here is merely a synonym for "if" or "any time after" and
    consequently conveys no sense of immediacy at all.              We then
    consider whether, even if Congress intended for the word "when" to
    convey    immediacy,   the   word   merely   reflects   a    legislative
    preference for timely action and thus does not impose a true time
    limit.
    31 Although the government suggests that Rojas construed
    "when" to mean, in effect, "any time after," Rojas did not, as it
    held that the word was irrelevant to § 1226(c)(2)'s operation.
    The government reads too much into Rojas's assertion that the
    "when . . . released" clause "specifies[s] the point in time at
    which [the Attorney General's] duty [under (c)(1)] arises." See
    Rojas, 23 I. & N. Dec. at 121.       In so stating, Rojas merely
    clarified that "when . . . released" modifies "take into custody"
    rather than the "alien" in (c)(1), not that "when" imposes no
    deadline. In fact, the BIA has seemed to set forth a time-limited
    meaning of "when" several times. See 
    id. at 122;
    see also Matter
    of Saysana, 24 I. & N. Dec. 602, 607 (BIA 2008); Matter of Valdez-
    Valdez, 21 I. & N. Dec. 703, 708 (BIA 1997). The government's
    interpretation of the meaning of the word "when" is thus not
    entitled to Chevron deference. Given that the BIA's position on
    the meaning of "when" is at worst inconsistent and at best
    consonant with petitioners' time-limited reading, we also would
    not defer under Skidmore to such an interpretation, assuming
    Skidmore deference even applies to the government's litigating
    position in this case. See Skidmore v. Swift & Co., 
    323 U.S. 134
    ,
    140 (1944) (stating that the opinion of an agency is entitled to
    respect only to the extent it has the "power to persuade").
    - 47 -
    A.
    We begin our analysis of the first issue with the
    observation that Congress chose a word, "when," that naturally
    conveys some degree of immediacy, 
    Castañeda, 769 F.3d at 42-44
    , as
    opposed to a purely conditional word, such as "if."     See Webster's
    Third New International Dictionary 2602 (2002) (defining "when" as
    "just after the moment that").         Consistent with the conclusion
    that this choice indicates that Congress intended for "when" to
    convey immediacy, § 1226(c)(1) says "when the alien is released,"
    not "when the alien has been released" or "after the alien is
    released."     Similarly,   the    structural     placement   of   the
    "when . . . released" clause suggests Congress did not use "when"
    simply to announce a condition, as the clause does not directly
    follow "any alien who."   Cf. Rojas, 23 I. & N. Dec. at 128-29.32
    If Congress really meant for the duty in (c)(1) to take
    effect "in the event of" or "any time after" an alien's release
    from criminal custody, we would expect Congress to have said so,
    given that it spoke with just such directness elsewhere in the
    IIRIRA.   See, e.g., 8 U.S.C. § 1231(a)(5) ("[T]he alien shall be
    32   The    Rojas    concurrence     suggested    that    the
    "when . . . released" clause in (c)(1) does not impose a timing
    constraint because it modifies only the offenses denominated in
    subparagraphs (A)-(D) of (c)(1), rather than the duty to "take
    into custody." See Rojas, 23 I. & N. Dec. at 128-29 (Moscato,
    concurring and dissenting). Neither the BIA, the government, nor
    our colleagues advance this view, however, and we see no basis for
    this view given the structural placement of the clause.
    - 48 -
    removed under the prior order at any time after the reentry."
    (emphasis added)); cf. United States v. Willings, 8 U.S. (4 Cranch)
    48, 54 (1807) (concluding that Congress intended the word "when"
    in a federal maritime statute to mean "if" or "in case" because
    the statute contained clear indicia of conditional intent (for
    example, the phrase "in every such case" recurred)).             In fact, the
    BIA itself noted in Rojas that "[§ 1226(c)] does direct the
    Attorney General to take custody of aliens immediately upon their
    release from criminal confinement."           Rojas, 23 I. & N. Dec. at 122
    (emphasis added).
    As   to   just   how    promptly     Congress   intended    for   the
    government    to   act,   there   is   more    uncertainty,   as   the   panel
    recognized when it construed the word "when" to mean "within a
    reasonable time after."      See 
    Castañeda, 769 F.3d at 44
    .          But given
    the unexplained, years-long gap between when these petitioners
    were released from criminal custody and when they were taken into
    immigration    custody,     we    need    not    define    the     bounds   of
    reasonableness in this case as they were plainly exceeded.33             Thus,
    33 The government and our colleagues contend that it is
    implausible that Congress would have exempted aliens from § 1226(c)
    merely in consequence of the remoteness of their release from
    criminal custody given that such a gap in custody might be
    attributable to other forces. See Gov. Br. at 8-9; see infra at
    83.   For example, the government and our colleagues point to
    evidence that some state and local authorities may frustrate the
    ability of the Attorney General to place aliens in custody in a
    timely fashion under (c)(1).    
    Id. But the
    agency charged with
    - 49 -
    for present purposes, it is enough to conclude that Congress used
    the word "when" to convey some degree of immediacy and not simply
    to set forth a condition.34
    administering the Act has not purported to define the word "when"
    or its temporal bounds, let alone how such period of time should
    be tolled in the circumstances the government and our colleagues
    identify or in other circumstances that might arise, such as when
    an alien receives a non-carceral sentence.      See Lora, 
    2015 WL 6499951
    , at *6; Kotliar, 24 I. & N. Dec. at 125; West, 22 I. & N.
    Dec. at 1410. We do not believe that such fact-specific questions
    about tolling provide a basis for concluding that "when" is best
    read in context to mean "if" or "any time after," given the other
    evidence of legislative intent.
    34 Our colleagues contend that the petitioners' view of "when"
    would be at odds with the canon against surplusage in light of the
    "released after" clause of the IIRIRA § 303(b)(2). But we do not
    see how. At worst, the "released after" clause is a clarifying
    provision in an ancillary and potentially never operative measure.
    Cf. In re Fahey, 
    779 F.3d 1
    , 7 (1st Cir. 2015) (indicating that
    language that is not strictly speaking necessary, if nonetheless
    clarifying, need not be thought to run afoul of the canon against
    surplusage). That is because the "released after" clause appears
    to have been intended to clarify which rules would apply to
    existing detainees when the TPCR expired.         Aliens who were
    immediately taken into immigration custody upon their release from
    criminal custody during the transition period were subject to the
    restrictions on bonded release imposed by the TPCR.      While the
    IIRIRA § 303(b)(2) did state the effective date of the new
    permanent rules § 1226(c) set forth, the "effective date" clause
    did not make clear whether the permanent rules or the by-then-
    expired TPCR rules would govern those persons in mandatory
    detention when the TPCR expired. Thus, the "released after" clause
    in the IIRIRA § 303(b)(2) would seem to have been intended to
    perform the useful function of making clear -- as part of a savings
    clause, see Garvin-Noble, 21 I. & N. Dec. at 681; Adeniji, 22 I.
    & N. Dec. at 1110-11 (emphasizing "uncertainty . . . in discerning
    how Congress expected the [released after] provision to operate,"
    given that Congress may have "intended" but inadvertently
    "neglected" to incorporate this provision into a broader savings
    clause in the TPCR) -- that § 1226(c) would apply only to aliens
    released from criminal custody "after" the transition period.
    Conversely, the old TPCR rules for mandatory detention would

    B.
    The part of the conference report to the IIRIRA that
    describes § 1226(c) supports the conclusion that Congress did not
    intend for the word "when" to have a purely conditional meaning.
    And so, too, does the legislative history to (c) that indicates it
    was meant to mirror the precursor mandates, each of which used a
    timing word that was understood to convey immediacy.
    The conference report states that "[t]his detention
    mandate   applies   whenever   such   an   alien   is   released   from
    imprisonment, regardless of the circumstances of the release."
    H.R. Conf. Rep. No. 104-828 (1996), 
    1996 WL 563320
    , at *210-11
    (emphasis added).    As used in that report, "whenever" is most
    plausibly read to mean at the time that the alien is released from
    imprisonment, whenever that event may occur, rather than simply
    "if" that event occurs.   Indeed, had Congress intended by the use
    of "whenever" to mean "if" or "any time after," we again would
    expect the report to have said "after such alien is released" or
    "whenever such an alien has been released."
    continue to govern aliens held in mandatory detention pursuant to
    those transition rules. Thus, the "released after" clause is by
    no means unnecessary if "when" conveys immediacy.     A misplaced
    concern about surplusage thus should not dictate a meaning of the
    word "when" that is so at odds with the text, structure, and
    legislative history. See King v. Burwell, 
    135 S. Ct. 2480
    , 2492-
    93 (2015).
    - 51 -
    Consistent with this conclusion, the legislative history
    to the subsection that would become § 1226(c) indicates that
    Congress intended to "restate[]" the provisions of the direct
    precursor to (c) "regarding the detention of an alien."           See H.R.
    Rep. No. 104-469(I) (1996), 
    1996 WL 168955
    , at *230.              And that
    direct precursor, which is codified in the AEDPA, used the word
    "upon," which was used in and understood to have conveyed immediacy
    in all the detention mandates preceding § 1226(c).35
    For example, the House Report on the 1990 amendments to
    the 1988 mandatory detention statute characterized "current law"
    as "requir[ing] [the] INS to incarcerate alien aggravated felons
    without bond immediately upon completion of the alien's criminal
    'sentence.'"     H.R. Rep. No. 101-681(I), § 1503, at 148 (1990),
    reprinted in 1990 U.S.C.C.A.N. 6472, 6554, 
    1990 WL 188857
    (emphasis
    added); cf. 
    Sheffield, 435 U.S. at 129-35
    . And the district courts
    that construed the word "upon" in the AEDPA's detention mandate
    reached   the   same   conclusion   as   Congress   had   about   the   1988
    measure -- its use of the word "upon" conveyed immediacy.               See,
    e.g., DeMelo, 
    936 F. Supp. 30
    , 36 (D. Mass. 1996), vacated as moot
    after the IIRIRA's passage, 
    108 F.3d 328
    (1st Cir. 1997).
    35In fact, as we have noted, just prior to conference on the
    IIRIRA, a leading Senate sponsor of the IIRIRA described § 1226(c)
    as "ensur[ing] that aliens who commit serious crimes are detained
    upon their release from prison until they can be deported . . . ."
    142 Cong. Rec. S10572-01 (daily ed. Sept. 16, 1996), 
    1996 WL 522794
    (statement of Sen. Simpson) (emphasis added).
    - 52 -
    In sum, the legislative history as a whole indicates
    that Congress used the word "when" just as it had used the word
    "upon": to convey a sense of immediacy.      We thus conclude that the
    legislative   history   reinforces     the   textual   indication   that
    Congress did not intend for the word "when" to be merely a synonym
    for "if" or "any time after."
    C.
    That brings us to the question of whether Congress
    intended for the word "when" merely to express a legislative
    preference for timely action or whether it was instead intended to
    impose a deadline for the application of the bar to bonded release
    set forth in § 1226(c).    To answer this question, we consult the
    principles underlying the so-called loss-of-authority canon.36
    36 Our colleagues, in concluding that "when" merely expresses
    a preference for timely action, do not rely on loss-of-authority
    principles. See infra at 98-99. They instead reason that even if
    Rojas is wrong, whether an alien was timely taken into immigration
    custody is just an exogenous fact and thus does not have any
    bearing on the class of aliens to whom § 1226(c) applies. See 
    id. If we
    follow, the suggestion appears to be that the word "released"
    and the trailing portions of the "when . . . released" clause do
    refer to something endogenous to the alien and thus do characterize
    the alien to whom (c) applies, even though the word "when" does
    not.   But aliens do not release themselves any more than they
    choose when they are released. We thus do not see how the line
    between exogenous and endogenous facts could be drawn so finely as
    to   attribute   to   Congress   an   intent   to  carve   up   the
    "when . . . released" clause in this odd way, even if there were
    any textual basis for construing the Attorney General's duty under
    (c) as being limited by facts endogenous to the alien rather than
    by all relevant ones. And, as noted, there is no textual basis
    for concluding that the word "when" -- and whatever limitations
    - 53 -
    That interpretive aid comes into play where Congress has
    mandated that the government "shall" do something within a certain
    time frame and there is a question about the consequence Congress
    intends for the government's failure to complete the required
    action within that time frame.    See Barnhart v. Peabody Coal Co.,
    
    537 U.S. 149
    , 158-59 (2003).     The canon generally counsels that:
    "[i]f a statute does not specify a consequence for noncompliance
    with statutory timing provisions, the federal courts will not in
    the ordinary course impose their own coercive sanction."          
    Id. at 159.
      The   animating   principle   behind   this   canon   is   one   of
    plausibility given the context: "if Congress had meant to set a
    counterintuitive limit on authority to act, it would have said
    more than it did."   
    Id. at 163
    (emphasis added).
    The government contends that § 1226(c) "contains no
    sanction for late executive action," Gov. Br. at 10, and that it
    would be counterintuitive to render (c) inapplicable when the
    that word imposes -- does not constrain the application of (c)(1),
    as the word clearly and unconditionally modifies the Attorney
    General's directive to "take into custody."     The only possible
    textual hook for distinguishing between endogenous and exogenous
    facts, therefore, resides in (c)(2)'s "described in" language.
    But making a distinction on this basis for the purpose of
    understanding the bounds of the Attorney General's duty under (c)
    would still create an arbitrary line-drawing problem. And such a
    distinction would also incongruously de-link the custody directive
    in (c)(1) from the bar to bonded release in (c)(2) by subjecting
    the custody directive to a timing constraint not applicable to the
    bar to release.
    - 54 -
    executive is late in taking an alien into custody given the
    detention-maximizing purpose underlying (c).                 But we do not agree.
    This case is not like those in which enforcement of a
    time limit would require a court to fashion a coercive sanction
    that appears nowhere in the text and that would completely strip
    the government of authority "to get [the] . . . job done," 
    id. at 160.
       See, e.g., 
    id. at 156
    (proposed sanction was complete loss
    of ability to direct award of retirement benefits to late-assigned
    beneficiaries); Brock v. Pierce Cty., 
    476 U.S. 253
    , 258 (1986)
    (proposed sanction was complete loss of ability to recover misused
    federal funds); Dolan v. United States, 
    560 U.S. 605
    , 609 (2010)
    (proposed sanction was complete loss of ability to order persons
    convicted    of    certain     crimes    to   pay     restitution    to   victims).
    Rather, the putative time limit at issue here appears in an express
    exception, § 1226(c), to an otherwise broad grant of discretionary
    authority, § 1226(a), regarding the custody and release of aliens
    awaiting the outcome of removal proceedings, just as all the
    precursors    to    §   1226(c)    were    framed      as   exceptions    to   then-
    equivalents of § 1226(a).           Thus, enforcement of the time limit
    here,   unlike     in    the   other    cases    in    which     loss-of-authority
    principles    were      applied,   would      merely    render    inapplicable    an
    express limit on a grant of authority and thus necessarily result
    in a reversion to that authority.
    - 55 -
    Given this distinct context, the key question is whether
    Congress intended for the requirement that the Attorney General
    timely take aliens into immigration custody to circumscribe the
    scope of this exception.      As a textual matter, there is no
    indication that Congress intended for subparagraphs (A)-(D) in
    § 1226(c)(1) but not the "when . . . released" clause to define
    the outer limit of the Attorney General's discretion that the
    exception in (c) establishes. The text of (c) also does not itself
    indicate that the timeliness of an alien's custody is merely a
    procedural requirement that need not be complied with in a strict
    sense.
    There remains the question whether it nevertheless would
    be counterintuitive to read "when" to circumscribe the exception's
    scope.    The express presentation of § 1226(c) as an exception to
    (a) that applies only if all of its conditions are met accords
    with the quite sensible intuition that Congress did mean to
    distinguish between aliens who fall within the scope of (a) and
    aliens who fall within the scope of (c) on the basis of the
    timeliness of their immigration custody.37      In construing the
    37 That Congress intended to craft a relatively narrow
    detention mandate is hardly implausible. After all, Congress did
    not adopt the recommendation in the 1995 Senate report to expand
    the class of aliens subject to mandatory detention to "all criminal
    aliens." See S. Rep. No. 104-48 (1995), 
    1995 WL 170285
    . Rather,
    setting aside any limitations imposed by the "when . . . released"
    clause, Congress limited mandatory detention under § 1226(c) to
    - 56 -
    intended scope of another aspect of § 1226(c), we explained in
    Saysana that "[i]t is counter-intuitive to say the least to say
    that aliens with potentially longstanding community ties are, as
    a class, poor bail risks."       See 
    Saysana, 590 F.3d at 17
    .      And we
    added that "by any logic, it stands to reason that the more remote
    in time a conviction becomes and the more time after a conviction
    an individual spends in a community the lower his bail risk is
    likely to be."      See 
    id. at 17-18.38
    Thus, in this context, we conclude that the timing word
    "when" is best read to impose an outer limit on the exception to
    the   categorical    bar   to   discretionary   release   carved   out   by
    § 1226(c).   In consequence, aliens like petitioners, who due to
    the unexplained years-long gap between their criminal custody and
    aliens who have committed certain enumerated offenses and who were
    "released after" the TPCR expired (by virtue of the IIRIRA
    § 303(b)(2)); see also 
    Saysana, 590 F.3d at 15-16
    (holding that
    § 1226(c)(1) is not triggered until an alien is released from
    custody for having committed an offense specified in subparagraphs
    (A)-(D), as opposed to being triggered by release from any type of
    criminal custody).
    38  The Second Circuit held that, to avoid "serious
    constitutional concerns," § 1226(c) "must be read as including an
    implicit temporal limitation," such that aliens taken into
    immigration custody pursuant to § 1226(c) cannot be held without
    a bond hearing for more than six months. Lora, 
    2015 WL 6499951
    ,
    at *10-11. In so holding, the Second Circuit noted that indefinite
    detention "has real-life consequences for immigrants and their
    families," and that it is particularly concerning when "[n]o
    principled argument has been mounted for the notion that [the
    detainee] is either a risk of flight or is dangerous." 
    Id. at *12.
    - 57 -
    their immigration custody have had the opportunity to re-establish
    community ties, are not subject to the bar to release set forth in
    (c). They are subject instead to the default rule of discretionary
    release set forth in (a).39
    To be sure, Congress was concerned about criminal aliens
    failing to show up for removal proceedings.         See Rojas, 23 I. & N.
    Dec. at 122.       But Congress expressly directed the executive to
    address that concern by complying with the mandate to pick up
    aliens    within   a   reasonable   time   frame.    In     fact,   Congress
    established    transition   rules   that   the   Attorney    General   could
    invoke to ensure the government would be prepared to comply
    promptly with § 1226(c) by the time those rules expired.                 See
    Adeniji, 22 I. & N. Dec. at 1110.
    As a result, we do not believe Congress intended that
    the executive could fail to pick up an alien within a reasonable
    time and then, despite that unexplained delay, deny that alien the
    chance to seek bonded release notwithstanding that alien's years
    of living freely.       See 
    Castañeda, 952 F. Supp. 2d at 318
    n.10
    39 Our colleagues' gardening example is of little help in
    establishing the context for discerning Congress's intent in
    enacting a detention mandate that "touches upon matters of both
    personal liberty and the control of our nation's borders." See
    infra at 76. As for our colleagues' suggestion that Congress had
    "no good reason" to distinguish between aliens timely taken into
    custody and aliens not timely taken into custody, our prior
    decision in Saysana supplies a compelling reason, see 
    Saysana, 590 F.3d at 17
    , as does Congress's treatment of § 1226(a) as a backstop
    source of detention authority.
    - 58 -
    ("[T]he   experience    of   having   one's    liberty    stripped    away   is
    drastically   different      from   the   experience     of   not   having   it
    restored."); cf. DeWitt v. Ventetoulo, 
    6 F.3d 32
    , 34-36 (1st Cir.
    1993) (holding that revoking a mistakenly granted suspension of
    sentence and re-imprisoning a defendant after years of being free
    violated due process).        And there certainly is nothing in the
    legislative   history   to    indicate     that   Congress    did   have   that
    specific intention.40
    For these reasons, the principal precedent that the
    government, like the Third Circuit in 
    Sylvain, 714 F.3d at 158
    -
    61, relies on, United States v. Montalvo–Murillo, 
    495 U.S. 711
    (1990), is not to the contrary.           That case concerned whether the
    government's failure to hold a bond hearing in a timely fashion
    barred the government from assuming pre-trial custody of a criminal
    defendant under the Bail Reform Act (BRA).           See Montalvo-Murillo,
    40 In fact, the legislative history accords with the notion
    that Congress wanted to limit § 1226(c) to aliens coming right out
    of criminal custody in order to help immigration authorities
    conserve scarce detention bed space so that aliens who needed to
    be detained under § 1226(a) could be. See Criminal and Illegal
    Aliens: Hearings Before the Subcomm. on Immigration and Claims of
    the House Comm. on the Judiciary, 104th Cong. (Sept. 5, 1996)
    (statement of David Martin, General Counsel of INS) (noting that
    criminal aliens subject to the AEDPA's detention mandate imposed
    severe burdens on detention bed space and crowded out space for
    aliens who did not come within such mandate and only discussing
    efforts by immigration authorities to take aliens into custody
    just as they were leaving incarceration); Amicus Br. of Frm. Imm.
    Judges and DHS Sec. Officials at 17-20 (describing scarce detention
    bed space).
    - 59 
    - 495 U.S. at 717
    .    Notably, but not surprisingly, the BRA specified
    no consequence for holding a hearing late.       And the Court thus
    held that such failure should not be deemed to have the drastic
    and disproportionate consequence of depriving the government of
    its power to place a criminal defendant in custody at all by
    mandating the release of the criminal defendant.     See 
    id. at 719-
    20.41
    Here, however, the putative time limit appears within an
    express exception to a grant of authority.    So § 1226 itself makes
    clear what consequence would follow if such time limit is not met.
    Moreover, that consequence would not strip the executive of the
    power to assume custody of a potentially dangerous or flight-prone
    criminal defendant.     Instead, the Attorney General would merely
    retain her otherwise broad discretion to decide whether to assume
    and maintain custody of an alien pursuant to whatever rules she
    41
    The Supreme Court's decision in 
    Barnhart, 537 U.S. at 152
    ,
    is similar. The appellants argued that a certain provision of the
    Coal Act specified the consequence for the government's failure to
    timely comply with another provision, 
    id. at 153,
    163, but the
    Court rejected this argument because the Coal Act's text did not
    expressly link the two provisions and there was evidence to suggest
    that Congress did not think of the two provisions as related. 
    Id. at 163
    -65. Moreover, the Court reasoned that it was implausible
    to think that Congress would have wanted that separate provision
    to control as a policy matter, so the consequence was untenable.
    
    Id. at 164.
    Here, of course, Congress expressly styled § 1226(c)
    as an exception that restricts the power otherwise granted under
    (a), so the asserted consequence is clearly linked to the asserted
    act of noncompliance. And, for the reasons discussed, we hardly
    think it is counterintuitive for Congress to have intended that
    (a) would control if (c)'s conditions are not met.
    - 60 -
    may lawfully establish for exercising such discretion under (a).
    Because this consequence follows from the text and because the
    text accords with the reasonable and intuitive understanding that
    Congress intended to distinguish between aliens like petitioners
    and aliens who were taken into custody "when . . . released," see
    
    Saysana, 590 F.3d at 17
    , we read the timing condition at issue
    here as circumscribing the Attorney General's duty under (c).
    Thus,   at   least      absent     an    authoritative     agency
    construction of § 1226(c)(2), we conclude that the word "when"
    does set forth a time constraint on (c) that expires after a
    reasonable time.     And for that reason, we reject the government's
    contention    that   "when"   must    be    read     merely   to   trigger   an
    indefinitely persisting duty, such that it imposes no outer bound
    on the scope of the exception § 1226(c) sets forth.
    IV.
    The current version of the detention mandate requires
    that aliens who have committed certain offenses be taken into
    immigration custody in a timely manner following their release
    from criminal custody.        The detention mandate further provides
    that only such aliens must then be held without bond until the
    completion of the removal process. These petitioners were released
    from criminal custody years before they were first placed in
    immigration custody.      For that reason, they clearly do not fall
    within "this detention mandate."              H.R. Conf. Rep. No. 104-828
    - 61 -
    (1996), 
    1996 WL 563320
    , at *210-11.   Accordingly, we agree with
    the two district courts that these petitioners have the right to
    individualized bond hearings at which they can make the case that
    they do not pose sufficient bond risks, just as the Attorney
    General specified in the regulations that she issued pursuant to
    § 1226(a).

    TORRUELLA, Circuit Judge (Concurring).   I recognize that
    the Supreme Court has determined that Congress may, "[i]n the
    exercise of its broad power over naturalization and immigration,
    . . . regularly make[] rules that would be unacceptable if applied
    to citizens," Mathews v. Diaz, 
    426 U.S. 67
    , 79-80 (1976); see also
    Demore v. Kim, 
    538 U.S. 510
    , 521 (2003), and that the right to
    bail is not absolute.    United States v. Salerno, 
    481 U.S. 739
    ,
    754-55 (1987).   Yet, I must register my discomfort with respect to
    8 U.S.C. § 1226(c).
    I am compelled to suggest that the indefinite detention
    without access to bond or bail of any person in the United States
    violates due process.    See Wong Wing v. United States, 
    163 U.S. 228
    , 238 (1896) ("[A]ll persons within the territory of the United
    States are entitled to the protection guarantied [sic] by th[e
    Fifth and Sixth] amendments [sic] . . . ."); Yick Wo v. Hopkins,

    process and equal protection provisions "to all persons within the
    territorial jurisdiction, without regard to any differences of
    race, of color, or of nationality").        The U.S. Constitution
    specifically addresses the right to bail.   It is the first concern
    of an amendment that names just three subject matters.   "Excessive
    bail shall not be required, nor excessive fines imposed, nor cruel
    and unusual punishments inflicted."    U.S. Const. amend. VIII.   As
    the Supreme Court has elsewhere noted, "[b]ail is basic to our

    Amendment mandates that no "person . . . be deprived of life,
    liberty, or property, without due process of law."                      U.S. Const.

    When the government exercises its discretion to subject
    a person to detention without access to a bond hearing after the
    condition     justifying      detention    has    been    in    existence    for    a
    considerable period of time, it disregards what is by then self-
    evident -- that said subject is neither a flight risk nor a danger
    to society, the primary reasons for denying bail.                   See 18 U.S.C.
    § 3142(e)(1); cf. Carlson v. Landon, 
    342 U.S. 524
    , 542 (1952)
    ("There is no denial of the due process of the Fifth Amendment
    under circumstances where there is reasonable apprehension of hurt
    from aliens charged with a philosophy of violence against this
    Government.").      Although Judge Kayatta, Chief Judge Howard, and
    Judge Lynch view this issue differently, infra at 104-05, this
    Court has elsewhere described their views as counter-intuitive.
    Saysana v. Gillen, 
    590 F.3d 7
    , 17-18 (1st Cir. 2009) ("[I]t is
    counter-intuitive to say that aliens with potentially longstanding
    community ties are, as a class, poor bail risks. . . . By any
    logic,   it    stands    to   reason    that    the    more    remote   in   time   a
    conviction     becomes    and   the    more     time   after    a   conviction      an
    - 64 -
    individual spends in a community, the lower his bail risk is likely
    to be.").    Affirming the government's prerogative to incarcerate
    persons in defendants' situation without bail or bond hearing is
    not only to allow arbitrary and abusive government action but to
    condone acts that run contrary to the Constitution.    See 
    Herzog, 75 S. Ct. at 351
    ; see also Wong 
    Wing, 163 U.S. at 237
    .
    I write separately to ensure that the constitutional
    concerns raised by § 1226(c) and the government conduct it commands
    -- the ongoing, institutionalized infringement of the right to
    bail and right to due process -- are formally acknowledged.
    Notwithstanding these concerns, we reach the conclusion we must in
    light of Congress's laws, legislative history, and the Supreme
    Court's holdings.   I thus concur in the judgment.

    KAYATTA, Circuit Judge, with whom HOWARD, Chief Judge,
    and LYNCH, Circuit Judge, join.            Congress enacted what is now
    8 U.S.C. § 1226(c) because of its concern that immigration judges
    had proven to be insufficiently accurate predictors of which aliens
    would "engage in crime and fail to appear for their removal
    hearings."       Demore v. Kim, 
    538 U.S. 510
    , 513 (2003); see S. Rep.
    No. 104-48, at 2 (1995) ("Despite previous efforts in Congress to
    require detention of criminal aliens while deportation hearings
    are pending, many who should be detained are released on bond.").
    To address this concern, Congress identified four categories of
    what Congress called "criminal aliens."                  8 U.S.C. § 1226(c).
    Section 1226(c), as signed by the President on September 30, 1996,
    as     part   of    the   Illegal    Immigration        Reform    and     Immigrant
    Responsibility Act of 1996 ("IIRIRA"), mandates, first, that the
    Attorney General "take into custody" these criminal aliens "when
    the alien is released" from criminal detention (the "custody
    mandate").       See 
    id. § 1226(c)(1).
        Section 1226(c) then mandates,
    second, an end to the practice of immigration judges trying to
    predict which of those criminal aliens will appear for removal
    proceedings if ordered to do so.              See 
    id. § 1226(c)(2).
             Under
    this    latter     mandate   (the   "no-release    mandate"),       the    Attorney
    General must not release the criminal alien from the Attorney
    General's     custody     pending   resolution     of    the     alien's    removal
    proceeding, unless release is necessary for protection of certain
    - 66 -
    persons in connection with an investigation into a major crime.
    See 
    id. The alien
    is, however, entitled to an immediate hearing
    to adjudicate any contention that the alien is not a criminal alien
    subject   to     section     1226(c)'s        mandates.         See   8   C.F.R.
    § 1003.19(h)(2)(ii).
    With its evenly divided vote, our court leaves in place
    two district court decisions holding that, to the extent the
    Attorney General fails to comply promptly with the custody mandate,
    immigration judges will find themselves back in the position of
    predicting     which   criminal   aliens      will   present    themselves   for
    removal if they are released on bail pending the conclusion of
    their removal proceedings.        Indeed, as we understand the reasoning
    of our colleagues who would affirm the decisions below, any failure
    by the Attorney General to achieve prompt compliance with the
    custody   mandate      renders   both   the    custody    and   the   no-release
    mandates inapplicable. For the reasons we explain in this opinion,
    we would instead join all four other circuits that have considered
    this issue by sustaining the Board's current practice in complying
    with section 1226(c).       See Lora v. Shanahan, No. 14-2343-PR, 
    2015 WL 6499951
    , at *8–9 (2d Cir. Oct. 28, 2015); Olmos v. Holder, 
    780 F.3d 1313
    , 1327 (10th Cir. 2015); Sylvain v. Attorney General, 
    714 F.3d 150
    , 161 (3d Cir. 2013); Hosh v. Lucero, 
    680 F.3d 375
    , 384
    (4th Cir. 2012).

    I.   Discussion
    We begin by explaining our view that the statute's
    mandates apply to petitioners, using the same tools of statutory
    construction that our colleagues employ to decide this case at
    step one of the Chevron analysis.       See Chevron, U.S.A., Inc. v.
    Nat. Res. Def. Council, Inc., 
    467 U.S. 837
    , 842–43 (1984).        We
    also explain why our colleagues' parsing of section 1226(c), even
    if correct, fails to support the conclusion that the Attorney
    General's failure to take a criminal alien into custody immediately
    upon release somehow eliminates any further requirement to comply
    with Congress's mandates set forth in section 1226(c).      Finally,
    although our colleagues do not reach Chevron step two, see 
    id. at 843,
    and therefore do not consider the constitutional avoidance
    argument that was relied upon in the vacated panel opinion, we do
    reach step two, and therefore briefly explain why that avoidance
    argument is not a valid basis for setting aside the Board of
    Immigration Appeals' ("BIA") reasonable interpretation of section
    1226(c).
    - 68 -
    A.   The Language and Structure of the Statute
    8 U.S.C. § 1226(a) grants the Attorney General the
    discretion whether to take into custody aliens charged with removal
    and whether to continue that custody pending the completion of
    removal proceedings:
    (a)  Arrest, detention, and release
    On a warrant issued by the Attorney
    General, an alien may be arrested and detained
    pending a decision on whether the alien is to
    be removed from the United States. Except as
    provided in subsection (c) of this section and
    pending such decision, the Attorney General--
    (1) may continue to detain the arrested
    alien; and
    (2) may release the alien on--
    (A) bond of at least $1,500 . . . ;
    or
    (B) conditional parole . . . .
    For   certain   aliens   classified   by   Congress   as   "criminal
    aliens," however, 8 U.S.C. § 1226(c) requires the Attorney General
    both to take the alien into custody and to maintain that custody
    without release subject to a narrow exception.         Section 1226(c)
    states in full:
    (c)    Detention of criminal aliens
    (1) Custody
    The Attorney General shall take into
    custody any alien who--
    (A) is inadmissible by reason of
    having committed any offense
    covered in section 1182(a)(2)
    of this title,
    (B) is deportable by reason of
    having committed any offense
    covered        in       section
    1227(a)(2)(A)(ii),    (A)(iii),
    (B), (C), or (D) of this title,
    - 69 -
    (C)   is deportable under section
    1227(a)(2)(A)(i) of this title
    on the basis of an offense for
    which the alien has been
    sentence [sic] to a term of
    imprisonment of at least 1
    year, or
    (D) is inadmissible under section
    1182(a)(3)(B) of this title or
    deportable    under    section
    1227(a)(4)(B) of this title,
    when the alien is released, without
    regard to whether the alien is released
    on   parole,   supervised   release,   or
    probation, and without regard to whether
    the alien may be arrested or imprisoned
    again for the same offense.
    (2) Release
    The Attorney General may release an
    alien described in paragraph (1) only if
    the Attorney General decides pursuant to
    section 3521 of title 18 that release of
    the alien from custody is necessary to
    provide protection to a witness, a
    potential witness, a person cooperating
    with an investigation into major criminal
    activity, or an immediate family member
    or   close   associate   of  a   witness,
    potential witness, or person cooperating
    with such an investigation, and the alien
    satisfies the Attorney General that the
    alien will not pose a danger to the
    safety of other persons or of property
    and is likely to appear for any scheduled
    proceeding. A decision relating to such
    release shall take place in accordance
    with a procedure that considers the
    severity of the offense committed by the
    alien.
    Each of the petitioners in this case, after arriving in
    this country, was convicted of one of the criminal acts listed in
    section 1226(c)(1)(A)-(D).   See Castañeda v. Souza, 
    769 F.3d 32
    ,
    36 (1st Cir. 2014), reh'g granted en banc.    There is no dispute
    - 70 -
    among the parties that section 1226(c) therefore plainly required
    the Attorney General: (1) to take petitioners into custody when
    they were released from incarceration, and (2) to detain them until
    the conclusion of their respective removal proceedings.         The
    question under consideration is what happens when, as here, the
    Attorney General does not manage to detain the criminal alien until
    after the alien's release from incarceration.
    All members of our en banc panel appear to agree that
    the mandate of paragraph (2) of section 1226(c) strictly limiting
    the release of certain persons once detained applies to anyone who
    is "an alien described in paragraph (1)."   So this case pivots, at
    least in the first instance, on determining the meaning of that
    phrase.   The BIA, in a quite straightforward fashion, construed
    that phrase to mean any alien who satisfies one of the adjectival
    descriptions set forth in subparagraphs (A)-(D) of paragraph (1)
    ("any alien who" "is inadmissible" or "is deportable" under the
    specified laws).   In re Rojas, 23 I. & N. Dec. 117, 121 (BIA 2001).
    Petitioners, and now three of our colleagues, argue instead--and
    this is crucial to their entire argument--that the pertinent
    description of the aliens in paragraph (1) clearly includes as
    well the adverbial phrase "when the alien is released" (emphasis
    added).   In this manner, our colleagues reason that if an alien
    was not detained by the Attorney General immediately "when the
    - 71 -
    alien [was] released," then that alien is not an alien "described"
    in paragraph (1).
    This attempt at deputizing an adverbial phrase into
    service as a description of the noun "alien" pays little heed to
    customary conventions of grammar and syntax.       "An adverb, an
    adverbial phrase, or an adverbial clause may qualify several parts
    of speech, but a noun is not one of them."   Theodore M. Bernstein,
    The Careful Writer, A Modern Guide to English Usage 23 (1965).
    Conversely, adjectives (like those in subparagraphs (A)-(D)) are
    "good friends of the noun."   H.W. Fowler, A Dictionary of Modern
    English Usage 10 (Sir Ernest Gowers ed., 2d ed. 1965); see also
    Merriam-Webster's Collegiate Dictionary 19 (11th ed. 2012).    We do
    not mean to say that there are never circumstances in which writers
    might employ an adverbial phrase in the manner employed by our
    colleagues.   Poetic license, after all, knows few bounds.   Rather,
    we say merely that if a straightforward reading of the text
    employing basic, conventional usages of grammar points directly at
    a given interpretation, it should take some pretty heavy lifting
    to reject that interpretation, much less to reject it as not even
    within the zone of reasonableness.
    Nor is grammar the only enemy of petitioners' preferred
    reading of the text. Structure argues against petitioners as well.
    After stating what the Attorney General must do to "any alien
    who--," paragraph (1) sets down in four separately indented and
    - 72 -
    lettered subsections the four clauses that plainly describe an
    alien, relegating the adverbial "when" phrase back to unlettered
    and unindented text. We thus not only have four adjectival clauses
    that obviously describe the noun "alien" and one adverbial phrase
    that less readily does so, but we also have a format that literally
    and visually sets the four descriptions apart from the adverbial
    phrase.    This structure directly reinforces the reading of the
    "when" phrase as qualifying the verb "take" in the clause "[t]he
    Attorney General shall take into custody" rather than as describing
    "any alien[s]."
    In so observing, we do not mean to overstate the case.
    Our colleagues make a fair point that the statute might have been
    more   clear   had   paragraph    (2)   referred   only   to   subparagraphs
    (A)-(D).    Of course, the fact that language might have been more
    clear--as it always could be--does not mean that it is not clear
    enough.    See Caraco Pharm. Labs., Ltd. v. Novo Nordisk A/S, 132 S.
    Ct. 1670, 1682 (2012) ("[T]he mere possibility of clearer phrasing
    cannot defeat the most natural reading of a statute . . . ."); cf.
    In re Fahey, 
    779 F.3d 1
    , 6 (1st Cir. 2015) (explaining that a
    statute's meaning was clear even though the statutory language
    could not "be read as entirely excluding the possibility" that a
    competing--but       ultimately     unpersuasive--interpretation         was
    correct). Relatedly, we note that Congress has on occasion, within
    the Immigration and Nationality Act ("INA"), referenced a general
    - 73 -
    subparagraph while clearly intending to refer only to the inset
    subclauses     within     that   subparagraph.          See,    e.g.,    8   U.S.C.
    §   1153(b)(5)(B)(i)      (referencing     8   U.S.C.    §     1153(b)(5)(A)     but
    clearly intending to cross-reference only the inset clauses (i)-
    (iii) within (A)).
    We    also   find   it   significant    that      the   language    and
    structure of section 1226(c) as a whole reveals that Congress
    actually     did     specify     which   criminal       aliens       described    in
    paragraph (1) may be released notwithstanding those aliens' prior
    commission of (A)-(D) crimes.              It described those aliens in
    paragraph (2).        And that description (of persons connected to
    government witnesses or investigations) plainly does not include
    petitioners.       Cf. TRW Inc. v. Andrews, 
    534 U.S. 19
    , 28 (2001)
    ("Where Congress explicitly enumerates certain exceptions to a
    general prohibition, additional exceptions are not to be implied,
    in the absence of evidence of a contrary legislative intent."
    (quoting Andrus v. Glover Constr. Co., 
    446 U.S. 608
    , 616–617
    (1980))).
    We have good company in concluding that it is reasonable
    to read section 1226(c) in this manner.             In describing the statute
    in the first sentence of Demore, the Supreme Court stated that
    section 1226(c) "provides that '[t]he Attorney General shall take
    into custody any alien who' is removable from this country because
    he has been convicted of one of a specified set of crimes." Demore,
    - 74 
    - 538 U.S. at 513
    .       As petitioners would have it, the Court should
    have added "and has just been released" as part of its description
    of the alien to whom the mandates were intended to apply.                   But it
    did not, presumably because it was focused on its recognition that
    Congress's goal was to end the practice of "releasing deportable
    criminal aliens on bond" in order to avoid what Congress decided
    was "an unacceptable rate of flight."             
    Id. at 520.
       Of course, the
    Court's description of the statute was not a holding. It certainly
    shows, though, that a pretty good reader of statutes easily reads
    the language as we do.        Cf. S.D. Warren Co. v. Me. Bd. of Envtl.
    Prot.,    
    547 U.S. 370
    ,   377    (2006)    (looking    to   how   the    court
    previously tended to use the term "discharge" in dicta under the
    Clean Water Act).
    In gauging the import of the foregoing textual analysis,
    we must also express a reservation concerning our colleagues'
    interpretative methodology.           At several steps in their analysis,
    they confront an interpretative guide that cuts against them (e.g.,
    adverbs    usually     do   not   describe     nouns,     the   layout      of   the
    subheadings supports a grammatical reading, the Supreme Court's
    short-hand summary of the statute is informative).               In each case,
    our   colleagues     correctly      note   that   the   guide   is    not   always
    dispositive. So far, so good. They then, however, proceed forward
    as if the import of those guides carries no continuing weight in
    the analysis and so does not undermine a conclusion that the
    - 75 -
    statute is actually plainly to the contrary.            We view that import,
    instead, as an accumulating weight capable of being offset only by
    evidence that speaks directly and unambiguously to the contrary.
    Silence,     assumptions,   inferences,       and   ambitiously    constructed
    lines of reasoning that were likely never within the contemplation
    of any drafter serve poorly as substitutes for such evidence.               See
    Rhode Island v. Narragansett Indian Tribe, 
    19 F.3d 685
    , 698 (1st
    Cir. 1994) ("[L]egislative history that is in itself inconclusive
    will rarely, if ever, overcome the words of a statute.").
    This is not to say that we end our own inquiry at this
    point.     To the contrary, we accept the notion that most statutes
    must be read with a sense of what Congress was trying to do, and
    that such a sense may be derived from knowledge gained outside the
    four corners of the text, keeping in mind the weighty role that
    the   text    must   continue   to    play.     We    also   agree   with   our
    colleagues--and with the BIA--that the statutory language is not
    so plain as to foreclose all extra-textual inquiry.               So, for that
    reason, and particularly because the actual language at issue
    touches upon matters of both personal liberty and the control of
    our nation's borders, we think it reasonable to look next at the
    legislative history to determine whether one can say that the
    straightforward, grammatically conventional reading of the statute
    comports with a reasonable interpretation of what Congress was
    trying to accomplish.
    - 76 -
    B.   Legislative History
    Our review of the legislative history begins with the
    most directly pertinent legislative history: the conference report
    to the IIRIRA.   Regarding section 1226(c) (i.e., section 236(c) of
    the law), the report states in full:
    New section 236(c) provides that the Attorney
    General   must   detain   an   alien  who   is
    inadmissible under section 212(a)(2) or
    deportable under new section 237(a)(2). This
    requirement does not apply to an alien
    deportable under section 237(a)(2)(A)(i) on
    the basis of an offense for which the alien
    has not been sentenced to at least 1 year in
    prison.   This   detention   mandate   applies
    whenever such an alien is released from
    imprisonment, regardless of the circumstances
    of the release. This subsection also provides
    that such an alien may be released from the
    Attorney General's custody only if the
    Attorney General decides in accordance with 18
    U.S.C. 3521 that release is necessary to
    provide protection to a witness, potential
    witness,   a   person   cooperating  with   an
    investigation into major criminal activity, or
    a family member or close associate of such a
    witness or cooperator, and such release will
    not pose a danger to the safety of other
    persons or of property, and the alien is
    likely to appear for any scheduled proceeding.
    H.R. Rep. No. 104-828, 
    1996 WL 563320
    , at *210-11 (1996) (Conf.
    Rep.).
    It is beyond dispute that the phrase "such an alien" as
    used in the third sentence of the conference report refers back to
    the aliens who are described in the first two sentences, neither
    of which contains (as either adjective or adverb) any requirement
    - 77 -
    that the person be recently released.        The third sentence simply
    tells us when the new custody mandate applies to "such an alien."
    It is also entirely fair to presume that the same phrase "such an
    alien" means the same thing in the fourth sentence's description
    of what the statute "also" provides for: the no-release mandate.
    This is, of course, simply another way of saying that the alien
    "described" in section 1226(c)(2)'s no-release mandate is an alien
    described in 1226(c)(1)(A)-(D)--the same class of alien who is
    subject to the custody mandate whenever released.                And since
    petitioners were admittedly subject to the custody mandate (i.e.,
    each is "such an alien") they are therefore subject to what section
    1226(c)(2) also provides for such an alien: the no-release mandate.
    We recognize that our colleagues manage to read even
    this directly authoritative legislative history as indicating that
    Congress intended to leave the no-release mandate contingent on
    how quickly the Attorney General complied with the detention
    mandate.   While we have much difficulty seeing this, we need only
    for   present   purposes   protest   that   such   a   reading   is   hardly
    compelling.     It is our colleagues, not us, who must claim a
    monopoly on reasonableness.
    We move next to the 1995 Senate Report that directly
    sets forth the substance of congressional concerns resulting in
    the enactment of the IIRIRA.     S. Rep. No. 104-48 (1995).       Treating
    the report as if it were Oz's man behind the green curtain, our
    - 78 -
    colleagues urge the reader to pay no attention to it.                   But the
    Supreme Court itself in Demore directly turned to this report for
    precisely the same purpose that guides us to look at the report:
    understanding the aims of Congress in enacting section 1226(c).
    See 
    Demore, 538 U.S. at 518
    –21 & n.4.              The Court--like us--has
    read this legislative history as plainly evidencing "Congress'
    concern    that,    even    with   individualized      screening,     releasing
    deportable criminal aliens on bond would lead to an unacceptable
    rate of flight."        
    Id. at 520.
           For example, the Senate Report
    emphasized that "[u]ndetained criminal aliens with deportation
    orders often abscond upon receiving [a notice of removal]. . . .
    (This notice is humorously referred [to] by some INS personnel as
    the 72 hours 'run notice.')"           S. Rep. No. 104-48, at 2-3; see
    
    Demore, 538 U.S. at 518
    -19 & n.4, 521.             The data before Congress
    likewise   supported       its   concern   that   immigration      judges   fared
    poorly in trying to predict which aliens would take flight once
    INS took steps to remove them.         S. Rep. No. 104-48, at 2 ("Over 20
    percent    of   nondetained      criminal     aliens   fail   to    appear    for
    deportation        proceedings.").          And     the   Senate       Report's
    recommendation that "Congress should consider requiring that all
    aggravated felons be detained pending deportation" due to "the
    high rate of no-shows for those criminal aliens released on bond,"
    - 79 -
    S. Rep. No. 104-48, at 32 (emphasis added), directly addressed--
    and is certainly entirely consistent with--this concern.
    Nor did Congress give any reason to think that this
    concern disappeared merely because the criminal alien was not
    detained for a period of time before deportation proceedings began.
    To the contrary, the "deportable criminal aliens [who] failed to
    appear for their removal hearings," 
    Demore, 538 U.S. at 519
    , were
    all those aliens who were not being held in INS custody.   In this
    respect, it is helpful to keep in mind the actual interpretation
    of the statute that petitioners urge.   They repeatedly argue that
    Congress would not have been concerned about allowing immigration
    judges to predict flight risk for criminal aliens who have "long
    since returned to their communities."    But their reading of the
    statute would mean that all criminal aliens who avoid detention
    "when . . . released" would be entitled to a shot at convincing an
    immigration judge that the alien would voluntarily surrender if
    removal is ordered.   And this would be so whether the alien has
    been free from prior criminal custody for a week or for five years,
    and no matter what the alien has done post-release.
    Of course, one could argue that the immigration judges
    will not release obvious flight risks.     But that is presumably
    what immigration judges were trying to do before Congress concluded
    that it had insufficient confidence in the immigration judges'
    ability to make ad hoc predictions, and opted for the categorical
    - 80 -
    treatment of four groups of aliens who are most likely to be
    removed.   To now say that the executive, merely by failing to
    detain a criminal alien promptly, can revive the immigration
    judges' ability to pick and choose who gets released on bail would
    be a result directly at odds with what Congress plainly sought to
    achieve.      Cf. King v. Burwell, 
    135 S. Ct. 2480
    , 2496 (2015)
    (rejecting an interpretation of the Affordable Care Act that would
    lead to the "result that Congress plainly meant to avoid").
    Nor does it help petitioners to argue that Congress's
    concern about recidivism is somehow inapplicable categorically for
    those criminal aliens who have "lived in the community" for some
    undefined period of time post-release.           In the first place, there
    is no compelling evidence in the record that Congress meant
    section 1226(c) to apply only when both reasons for its enactment
    --avoiding flight and re-offense--would be served.              Second, just
    as Congress found unacceptable the mere possibility of recidivism
    among this category of criminal aliens during the period between
    release from criminal custody and removal adjudication, there is
    no basis in the record for presuming that Congress felt that
    immigration    judges   would   be    in   a   position   to   discount   that
    possibility merely by noting that the criminal alien had been
    released some time ago.         The immigration judges will both lack
    much knowledge about what the criminal alien has been doing since
    release and have no ability to predict future behavior that is
    - 81 -
    materially greater than the ability found by Congress to be
    insufficient.
    The legislative record, like Conan Doyle's dog that did
    not bark, also conveys much by what it does not say.      See Chisom
    v. Roemer, 
    501 U.S. 380
    , 396 & n.23 (1991).   Imagine, for example,
    that petitioners were correct: if a criminal alien were not
    detained immediately upon release from prison, that alien would
    have a right to convince an immigration judge that the alien is
    not a flight risk.   And, as our colleagues read the statute, this
    right would belong to every alien not detained upon release,
    whether or not the alien settled in any community, or took efforts
    to hide, or even went on a crime spree. If that had been Congress's
    aim, it is unlikely that there would be no acknowledgement of such
    a loophole, nor any language in the statute defining and limiting
    the loophole.
    Similarly, if the entire mandatory detention regime
    hinged on whether the criminal alien was detained "when . . .
    released," one would have expected Congress to pay some attention
    to defining that term.    How much time is too much?     What if the
    alien hides?    What if the alien commits a new crime?   What if the
    state prison does not cooperate, making it impossible for federal
    agents to know when the alien will leave state custody?     There is
    no evidence that Congress viewed its legislation as raising such
    questions, all of which would have been nose-on-the-face obvious
    - 82 -
    had Congress intended the statute to be read as petitioners would
    have us read it.   Precisely to the contrary, the entire focus was
    broadly and categorically on "[u]ndetained criminal aliens."         See
    S. Rep. No. 104-48, at 2.
    Particularly noteworthy in this regard is the fact that
    the drafters were well aware of--and concerned about--the fact
    that criminal aliens were avoiding detention because some state
    and local authorities refused to let INS know when criminal aliens
    were being released.    See S. Rep. No. 104-48, at 16-17, 22.        Yet,
    if petitioners are correct, Congress gave the state and local
    authorities   hostile   to   Congress's   aim   complete   ability     to
    frustrate pursuit of that aim.
    Our knowledge of how Congress chooses to affect the
    removal process of criminal aliens in other provisions of the U.S.
    Code dovetails with our understanding of Congress's purpose in
    enacting section 1226(c).     For example, Congress, in the IIRIRA,
    barred from eligibility for cancellation of removal any permanent
    resident alien convicted of an aggravated felony.42        See Pub. L.
    No. 104-208, 110 Stat. 3009-594 (creating 8 U.S.C. § 1229b(a)(3));
    Rojas, 23 I. & N. Dec. at 121-22.     Congress also stripped courts
    of jurisdiction "to review any final order of removal against an
    42An alien who is "deportable by reason of having committed"
    an aggravated felony falls under section 1226(c)(1)(B). Compare
    8 U.S.C. § 1226(c)(1)(B), with 
    id. § 1227(a)(2)(A)(iii).
                                  - 83 -
    alien who is removable by reason of having committed" certain
    criminal offenses that are also listed as predicate offenses under
    section 1226(c)(1)(A)-(C).            See 8 U.S.C. § 1252(a)(2)(C); Rojas,
    23 I & N Dec. at 122.43               The aliens described in (A)-(D) are
    therefore more likely to lose--and more likely to expect to lose
    --in a removal proceeding, thus increasing the incentive to flee
    once they are on Immigration and Customs Enforcement's ("ICE")
    radar. It therefore seems natural to conclude that Congress wanted
    these        aliens   to   be   in   custody   when   the   removal   proceeding
    concluded, whether or not they were taken into custody right when
    previously released.
    Congress's focus in related legislation on making it
    more difficult for criminal aliens to successfully contest a
    removal order also reinforces the view that Congress aimed to deal
    with such aliens categorically.            In saddling criminal aliens with
    many burdens not imposed on aliens who reside in the United States
    43
    The INA contains numerous other examples of ways in which
    Congress has made it more difficult for criminal aliens to avoid
    removal. For instance, in removal proceedings, lawful permanent
    residents convicted of crimes involving moral turpitude may not
    qualify for a discretionary waiver of removability, because
    commission of a crime of moral turpitude tolls the accrual of the
    seven years of residence required for cancellation of removal.
    See 8 U.S.C. § 1229b(d)(1).     Other aliens convicted of a crime
    involving moral turpitude may not qualify for cancellation and
    adjustment to lawful permanent resident status.            See 
    id. § 1229b(b)(1)(C).
    Additionally, aggravated felons may not seek
    asylum, see 
    id. § 1158(b)(2)(A)(ii),
    (b)(2)(B)(i), nor may they
    seek persecution-based withholding of removal if they have been
    sentenced to five years or more in prison, see 
    id. § 1231(b)(3)(B).
                                  - 84 -
    without       committing   crimes     viewed   by   Congress       as    especially
    relevant to immigration status, see supra note 43, Congress has
    drawn    no    distinction    based    on   when    the    alien    is    detained.
    Evidence of living in the community for years post-release does
    not    eliminate    the    legal    disabilities    in     removal      proceedings
    imposed by the prior commission of certain criminal acts.                   On the
    contrary, during the years preceding the IIRIRA and within the
    IIRIRA itself, Congress actively sought to narrow the group of
    criminal aliens eligible for relief based on duration of residency.
    For example, prior to the IIRIRA, many aliens with "a lawful
    unrelinquished domicile of seven consecutive years" could seek
    relief from removal despite their prior criminal activity.                      See
    INS v. St. Cyr, 
    533 U.S. 289
    , 295 (2001) (quoting section 212(c)
    of the INA, formerly codified as 8 U.S.C. § 1182(c)).                    This sort
    of relief had "great practical importance," 
    id., and "the
    class of
    aliens whose continued residence in this country . . . depended on
    their eligibility for § 212(c) relief [was] extremely large, and
    not surprisingly, a substantial percentage of their applications"
    were granted, 
    id. at 295-96.
             After amendments to the INA in 1990
    and 1996 narrowed the availability of section 212(c) relief, the
    IIRIRA eliminated it and replaced it with an even narrower class
    of    lawfully    admitted   permanent      resident      aliens   who    had   been
    lawfully present for at least five years and had not been convicted
    of an aggravated felony.           See 
    id. at 297;
    8 U.S.C. § 1229b(a).
    - 85 -
    We   have   also     considered   the   language   governing
    section 1226(c)'s effective date, IIRIRA, § 303(b)(2), 110 Stat.
    3009, 3009-586, and the IIRIRA's Transition Period Custody Rules
    ("TPCR"), IIRIRA, § 303(b)(3), 110 Stat. at 3009-586 to -587.44      We
    agree with our colleagues that such language, as part of the very
    statute at issue, provides a source of potential insight into the
    meaning of its companion terms.        See Gutierrez v. Ada, 
    528 U.S. 250
    , 255 (2000).    That insight runs in favor of the interpretation
    we adopt.
    Most notably, the effective date provision states that
    section 1226(c) "shall apply to individuals released after" the
    expiration of the TPCR.        IIRIRA, § 303(b)(2), 110 Stat. at 3009-
    586.    That clause would be superfluous if petitioners were correct
    that the detention-without-release mandate applies only to aliens
    who are picked up right away, because immediate detention would be
    impossible for aliens who had already been released prior to the
    TPCR's expiration date.    See Nat'l Ass'n of Home Builders v. Defs.
    of Wildlife, 
    551 U.S. 644
    , 669 (2007) ("[W]e have cautioned against
    reading a text in a way that makes part of it redundant.").        While
    we acknowledge the Supreme Court's recent reiteration that its
    44
    The TPCR imposed a more permissive regime that, due to
    Congress's concerns about bed space shortages, governed bond
    determinations for two years after the IIRIRA's effective date and
    prior to section 1226(c)'s full implementation.       See IIRIRA,
    § 303(b)(3), 110 Stat. at 3009-586 to -587.

    "preference   for   avoiding   surplusage   constructions   is   not
    absolute," 
    King, 135 S. Ct. at 2492
    (internal quotation mark
    omitted), the canon provides at the very least yet another thumb
    to be added to grammar, structure, and legislative purpose on the
    scale in favor of our interpretation.45
    That thumb is particularly large in this case, where
    (unlike in King), Chevron applies.   See 
    King, 135 S. Ct. at 2488
    –
    89 (declining to apply the Chevron two-step framework because if
    "Congress wished to assign [interpretation] to an agency, it surely
    would have done so expressly").   Here, we are first asked whether
    Congress has spoken clearly and directly to the question at issue,
    and second whether the BIA's interpretation is a reasonable one.
    The surplusage caused by petitioners' interpretation at once makes
    the interpretative path they walk less direct and the BIA's reading
    in Rojas more reasonable.   Cf. Nat'l Credit Union Admin. v. First
    Nat'l Bank & Tr. Co., 
    522 U.S. 479
    , 501 (1998) (rejecting, under
    Chevron step one, agency's interpretation in part because it made
    "the phrase 'common bond' surplusage").
    45We agree with the actual holding in Saysana v. Gillen, 
    590 F.3d 7
    , 18 (1st Cir. 2009), that section 1226(c) does not apply to
    aliens released from custody for their (A) through (D) offenses
    prior to the IIRIRA's effective date. To the extent that one might
    glean from Saysana any inferences concerning the issue presented
    here for the first time, such inferences would not be binding on
    our en banc court.    See United States v. Gonzalez-Arimont, 
    268 F.3d 8
    , 13 (1st Cir. 2001).
    - 87 -
    Even putting to one side the surplusage ramification,
    the TPCR provides no support for petitioners' position because it
    simply    raises   the   same   interpretative   question   that   section
    1226(c) poses: do the custody and no-release mandates during the
    transition period apply if there is a delay in detaining the alien?
    Our colleagues nevertheless attempt to glean from the TPCR two
    points of support that warrant our consideration.
    First, they point out that the transition rules set forth
    in the TPCR contain language stating that, should the Attorney
    General as anticipated invoke the transition rules, § 1226(c) will
    apply only to persons released after expiration of the transition
    period.    The rules contain no similar provision stating that the
    mandates in the transition rules themselves apply only to aliens
    released after the transition rules become effective.        This means,
    our colleagues reason, that under our interpretation the breadth
    of the mandate's duty imposed on the Attorney General under the
    permanent rules of section 1226(c) would be "less sweeping than
    the supposedly more flexible TPCR mandate's bar had been" even
    though the TPCR was intended to accommodate the Attorney General's
    need to ramp up resources. The way to fix this "anomalous" result,
    our colleagues argue, is to read the TPCR's bar on releasing aliens
    to apply only to those taken into custody "when . . . released."
    And if one reads the TPCR that way, by analogy one should read
    section 1226(c) that way.       Anomaly cured.
    - 88 -
    In this manner, our colleagues imagine a problem that
    does not exist in order to advocate a solution that is not
    required.    There is no need to interpret the TPCR in this manner
    to make its duties "less sweeping" than those imposed by section
    1226(c).    The TPCR, unlike section 1226(c), expressly allows the
    Attorney General to release any detained aliens who fall into two
    of the four groups of aliens described in both the TPCR and section
    1226(c).    Our colleagues offer no evidence at all establishing
    that the effect of this categorical exclusion does not swamp
    whatever    burden    might   arise    as    a    result    of   the   theoretical
    possibility that the Attorney General within the brief two-year
    transition period might pick up criminal aliens who had not been
    released from criminal custody during that period.
    More     fundamentally,      our      colleagues'      premise    that
    language in the TPCR need be rendered superfluous in order to cure
    a   perceived   "anomaly"     between       the   TPCR     and   section   1226(c)
    incorrectly presumes that it was possible to start up a new regime,
    with differing transition rules, and not have some "anomalies."
    For example, what was to be done with an alien who was released
    from prison during the transition period, and who then moved for
    bail after the expiration of the transition period?                     Under the
    language of the transition rules--and under either interpretation
    of section 1226(c) proffered in this case--such a person would
    suddenly have a shot at bonded release that he might not have had
    - 89 -
    if he had moved for bail before the transition period had expired
    (i.e., the section 1226(c) detention mandates would be "less
    sweeping").   See In re Adeniji, 22 I. & N. Dec. 1102, 1110-11 (BIA
    1999).   Certainly such an anomaly provides no license to re-write
    section 1226(c).    It does, however, make clear that some such
    anomalies arise inevitably from the need to have some arbitrary
    cut-offs for implementing new programs.
    Second, our colleagues complain that, in some instances,
    the BIA's reading of section 1226(c) would have "de-linked" or
    "misaligned" the custody and no-release aspects of section 1226 if
    the TPCR transition rules had not been invoked because the clause
    in the TPCR limiting section 1226(c) as a whole to persons released
    after the TPCR became effective would not have been triggered.   As
    an example, our colleagues point to a suspected terrorist described
    in subsection 1226(c)(1)(D) who has never been imprisoned and who
    is roaming the streets.      Under the BIA's interpretation, the
    Attorney General would reserve the ability to decide whether to
    arrest such a person because the custody mandate would not have
    been triggered by a prior release.      Once the Attorney General
    decided the suspected terrorist should be detained, under the BIA's
    reading of section 1226(c)(2), as it would apply had the transition
    period not been implemented, no immigration judge would have the
    discretion to release the alien unless the alien prevailed in the
    removal proceeding.   Our colleagues apparently think this is an
    - 90 -
    obviously unsound result, and that Congress must have intended
    that immigration judges could second guess the Attorney General
    and order such an alien released.       How one reads Congress's
    manifest unhappiness with the predictive failure of immigration
    judges as supporting such a conclusion puzzles us.46
    Our colleagues also lean hard on the meaning they derive
    from section 1226(c)'s predecessors.     We agree with the BIA's
    position in Rojas that, while none of the other predecessor
    provisions shed helpful light on the issue to be decided in this
    case, the post-1991, pre-AEDPA version of the custody and no-
    release mandates is instructive.    Rojas, 23 I & N. Dec. at 123-
    24.    That version, embodied in section 242(a)(2) of the INA
    following the 1990 and 1991 amendments,47 provided that:
    46 Our colleagues point out that there is no legislative
    history suggesting that Congress was more hostile to the discretion
    of immigration judges in determining whether to grant bonded
    release to a criminal alien than to the discretion of immigration
    enforcement in determining whether to bring a criminal alien into
    immigration custody in the first place. But this is immaterial.
    Given that we apply Chevron deference, it is incumbent on our
    colleagues to demonstrate that it clearly lay outside of Congress's
    intent to adopt a statutory scheme that would not require
    immigration enforcement to track down and detain each and every
    criminal alien, including the low-level narcotics offender, but
    that would allow immigration enforcement to rest assured that
    efforts to detain those criminal aliens who do represent
    enforcement priorities would not go for naught due to the
    miscalculation of an immigration judge at the alien's bond hearing.

    whether the alien was convicted of an aggravated felony, "unless"
    the alien is able to demonstrate that he is not a bond risk.     There
    is nothing in that version of the statute that even remotely
    suggests that a lapse in establishing custody removes an alien
    from the scope of subparagraph (B)'s coverage.    And notably absent
    from subparagraph (B) is any mention of subparagraph (A) or its
    "upon release" language (i.e., the "when . . . released" clause's
    equivalent).   This is a problem for our colleagues and petitioners
    because, once again, that textual reference point is the only hook
    - 92 -
    they latch on to in concluding that the description of aliens
    subject to the no-release mandate includes a timing element.
    Simply put, the language of the most long-standing version of the
    no-release mandate prior to the IIRIRA does not appear to contain
    any of the ambiguity that section 1226(c) arguably possesses with
    respect to the relevance of the timing of release.               None of the
    language in the predecessor provisions to which our colleagues
    point contains this level of clarity on this key point.               And if
    our colleagues' position that Congress has never sought to alter
    the relationship between the custody and no-release mandates is
    correct, this would seem to doom their argument.
    Our colleagues point, instead, only to an off-point BIA
    opinion, Matter of Eden, 20 I. & N. Dec. 209 (BIA 1990), as
    reflecting the pre-IIRIRA law that Congress sought to preserve.
    But the question of whether a delay in detaining a criminal alien
    eliminated the Attorney General's obligation to deny bond once the
    alien was detained was not even raised as an issue in Eden. Rather,
    the case involved an alien who had been taken into immigration
    custody while on "special parole" as part of his criminal sentence.
    The   question   posed   was   whether   subjecting   such   a    person   to
    mandatory immigration custody without bond was inconsistent with
    "Congress' decision to allow [an] alien serving time in [a] state
    or local facility to finish out that time before the Service
    assumes responsibility for his incarceration."         
    Id. at 214.
                                      - 93 -
    It is true that, under Rojas's reasoning, the BIA perhaps
    could have reached the same result in Eden merely by saying that
    once a criminal alien was detained, he could not be granted bond
    regardless of whether he had yet been released from prior custody.
    Even under that approach, though, the BIA would have had an
    interest    in   clarifying   the   scope   of   the   Attorney   General's
    statutorily mandated duty to detain a criminal alien--and, namely,
    in clarifying whether conceiving of a duty on the Attorney General
    to detain a person too soon (i.e., during the course of a prior
    sentence)    ran   up   against   the   congressional    intent   expressed
    through the 1988 legislation's "upon release" provision.            In any
    event, the simpler point is that there is no holding in Eden,
    either express or implied, that addresses the issue posed here.48
    Compounding their attempt to glean a holding--much less
    settled law--from Eden, our colleagues then simply misread the
    House report to the 1990 legislation that revised the clause "upon
    completion of the alien's criminal sentence" to read "upon release
    of the alien (regardless of whether or not release is on parole,
    supervised release, or probation . . . .)."            Rightly or wrongly,
    the report plainly states that Congress was concerned that "[a]t
    least one immigration judge has ruled that an aggravated felon who
    has been paroled by the sentencing court continues to serve his
    48   Not even the dissent in Rojas cites Matter of Eden.
    - 94 -
    'sentence' [and therefore] INS has no authority to incarcerate
    this alien until his period of parole has ended."           H.R. Rep. No.
    101-681, pt. 1, at 148 (1990), as reprinted in 1990 U.S.C.C.A.N.
    6472, 6554 (emphasis added).    In short, Congress was fearful that
    its mandate to take criminal aliens into custody without bond upon
    completion of the sentence was being construed as divesting INS of
    any authority to detain an alien while the alien was on parole.
    Restoring that authority implied a "link" to the no-release mandate
    only in the obvious sense that any elimination of INS's authority
    even to take a person into custody obviously frustrates any mandate
    that the person be kept in custody.         Nothing in this sort of
    logical link in any way implies (much less compels) a conclusion
    that the custody and the no-release mandates are "linked" in the
    sense that our colleagues' analysis requires.         To the contrary,
    the fact that Congress wanted even those criminal aliens who would
    otherwise be subject to parole reporting and supervision to be
    detained during their removal proceedings would seem to cut against
    our colleagues' assumption that a brief period of unsupervised
    living in the community eliminated the need for detention.
    This type of error (presuming that any reference to
    "immediate"   detention   without   bond   implies   that    a   delay   in
    detention makes a bond possible) pervades our colleagues' entire
    discussion of the legislative record.          When we see Congress
    repeatedly emphasizing that the government must take criminal
    - 95 -
    aliens into custody "when," "upon," or "immediately upon" their
    release, and then not release them, we see no implied loophole.
    Rather, we see an increasingly urgent expectation that criminal
    aliens should be found in custody when the removal decision issues.
    We stress, too, that even if one were to ignore these
    defects in our colleagues' survey of the legislative history, the
    most one ends up with are efforts to infer an answer to the question
    at hand from statements made in addressing other issues where the
    resolution of those other issues did not require or even call upon
    a degree of precision that would be necessary to confirm the force
    of the inference.      And in each instance, the actual resolution of
    the   issue    at   hand   is    completely   compatible   with   the   BIA's
    conclusion in Rojas.       Inferences of this type, whether reasonable
    or not, seem to us to fall far short of the "clear" legislative
    record one should require to end the inquiry at Chevron step one.
    Turning their focus from the 1991 amendment and its
    predecessors, our colleagues repeat their error in claiming that
    we should presume that, in enacting the IIRIRA, Congress was aware
    of the fact that "district courts . . . treated the retained 'upon
    release' clause [of AEDPA] as if it conditioned the retained 'such
    felon clause.'" Supra at 38-39. Our colleagues cite five district
    court cases as constituting this "existing law" of which Congress
    was supposedly aware.           Three are actually holdings that address
    retroactivity under AEDPA.          Montero v. Cobb, 
    937 F. Supp. 88
    (D.
    - 96 -
    Mass. 1996); Villagomez v. Smith, No. C96-1141C, 
    1996 WL 622451
    (W.D. Wa. July 31, 1996) (unpublished); DeMelo v. Cobb, 936 F.
    Supp. 30 (D. Mass. 1996), vacated, 
    108 F.3d 328
    (1st Cir. 1997)
    (per curiam).    As for the fourth, we sincerely doubt that Congress
    managed to dredge up an obscure unpublished opinion from the
    Southern District of Texas, which to this day remains difficult to
    locate.     See In re Reyes, Case No. B-94-80 (S.D. Tex. May 31,
    1996).     The fifth, Grodzki v. Reno, 
    950 F. Supp. 339
    (N.D. Ga.
    1996), is arguably on point, but was not issued until September 20,
    1996, just ten days before the already drafted IIRIRA was passed
    into law.    See Pub. L. No. 104-208, 110 Stat. 3009.           In any event,
    even were all five cases squarely apposite, five district court
    opinions    could    not   establish     the   type   of   "settled   judicial
    construction" as to which we presume congressional awareness.                 See
    United States v. Powell, 
    379 U.S. 48
    , 55 n.13 (1964) (four lower
    court opinions, including two by circuit courts, insufficient).
    In   sum,   against   a     legislative    backdrop     thick    with
    indications that Congress aimed to ensure that criminal aliens not
    go free prior to the conclusion of their removal proceedings, our
    colleagues stake their reading of the statute on one off-point BIA
    ruling, one district court decision issued ten days prior to the
    IIRIRA's enactment, and the supposedly anomalous results derived
    from   reading      section   1226(c)    in    conjunction   with     what   our
    colleagues themselves describe as "an ancillary and potentially
    - 97 -
    never operative clause in the TPCR," supra at 30-31 n.23.                    In view
    of   the   foregoing,     one      might    argue       that    section    1226(c)'s
    legislative    history       actually      compels        a    finding     that     the
    straightforward, grammatically conventional reading of the statute
    must be correct.       Instead, tempering our confidence in our own
    interpretative analysis, we need opine at this point only that the
    legislative history is not so clearly to the contrary as to compel
    a finding that "Congress has directly spoken to the precise
    question at issue" (much less that it spoke with the intent our
    colleagues claim is clearly apparent).

    C.    Our Colleagues' Conclusion Falls Short of the Mark
    We have explained our disagreement with our colleagues'
    argument   that   no    reasonable       jurist     can    read   the     phrase   "as
    described in paragraph 1" as not incorporating into paragraph 2
    the phrase "when released . . . ."               Even if we are wrong, though,
    we agree with the Second, Third, Fourth, and Tenth Circuits that
    the Attorney General's delay in detaining petitioners does not
    render the no-release mandate inapplicable.                    Our sister circuits
    have explained why this is so under the loss-of-authority rubric.
    See Lora, 
    2015 WL 6499951
    , at *8; 
    Olmos, 780 F.3d at 1324
    –26;
    
    Sylvain, 714 F.3d at 157
    –61; 
    Hosh, 680 F.3d at 381
    –83.                     We prefer
    to   reframe   the   point    as    a    matter    of     interpreting     the     text
    consistently with the purpose manifest in the text.                  The key point
    here is that even if the no-release mandate of paragraph (c)(2)
    - 98 -
    applied by its terms only to persons who have been released from
    criminal custody, there is no good reason to say also that it
    applies only when the Attorney General complies with the custody
    mandate by detaining the criminal aliens right when they are
    released.
    Consider the following example that we have crafted so
    that its substance and evident purpose invite the type of reading
    that our colleagues insist is applicable to section 1226(c).
    (1) Please give an especially thorough watering to any
    plant that is:
    (A) a sunflower, or
    (B) a hibiscus
    when it is planted for the garden show.
    (2) Do not let a plant described in paragraph (1) go
    any day without water unless you are certain that
    it is dead.
    Under the scenario posed by this example, we would agree
    that it is reasonable to read the reference to plants "described
    in paragraph (1)" as indicating not all sunflower or hibiscus
    plants, but rather as indicating sunflower or hibiscus plants that
    are newly planted for the garden show.        This is because our
    knowledge that certain new plantings need prompt and regular
    watering gives us a clue for resolving any ambiguity created by
    the structure and awkward syntax of the mandates.
    Nevertheless, even in this example designed to welcome
    the type of reading that our colleagues give to section 1226(c),
    it simply does not follow that the mandate of section (2) is also
    - 99 -
    contingent upon prompt compliance with the mandate of section (1).
    No reasonable person would let the plants in question continue to
    go without water merely because impediment or neglect unduly
    postponed the first watering.
    Of course, this conclusion, too, follows in great part
    from an assumption that the principal purpose of the mandates is
    to keep the new plants alive.     In the case of section 1226(c), an
    analogous (and actual) purpose is manifest in the legislative
    history discussed in this opinion and in Demore.      In repeatedly
    and even more broadly expressing dissatisfaction with criminal
    aliens not being in custody when removal is ordered, Congress did
    not order the Attorney General to detain such aliens only if she
    chose to do so right away.       Rather, we read section 1226(c) as
    ordering the Attorney General to detain such persons, and to do it
    right away.    The question whether the Attorney General complied
    with that mandate right away--like the question whether the plants
    were watered promptly when planted--is simply an exogenous and
    independent fact that is not part of the description of those to
    whom either mandate applies.49
    49 Our colleagues suggest that our distinction between
    exogenous and endogenous characteristics cuts too fine. We will
    simplify. Section 1226(c)(1), under any reading, both creates a
    duty and describes a group of people as to whom that duty must be
    carried out. We see how section 1226(c)(2)'s reference to a person
    "described in" section 1226(c)(1) could reasonably be understood
    to refer to a member of the delineated group as to whom the duty
    - 100 -
    D.   The Constitutional Avoidance Canon
    Since our colleagues rest their decision on Chevron's
    first step, they do not reach the constitutional avoidance argument
    principally relied upon by petitioners and by the panel opinion we
    vacated prior to hearing this appeal en banc.             See Warger v.
    Shauers, 
    135 S. Ct. 521
    , 529 (2014) (constitutional avoidance canon
    "has no application in the absence of . . . ambiguity" (omission
    in original) (internal quotation marks omitted)); 
    Olmos, 780 F.3d at 1321
    (citing Warger in declining to consider the canon for
    purposes of Chevron step one).         Because we disagree with our
    colleagues' conclusion that no reasonable person can read the
    statute   other   than   as   they   read   it,   we   explain   why   the
    constitutional avoidance canon, even if it may be appropriately
    applied at Chevron step two,50 does not remove the BIA's decision
    exists.    But we simply fail to see how a reasonable reader
    construes the cross-reference as referring to a member of the
    delineated group as to whom the duty was in fact immediately
    executed.    Section 1226(c)(1), which creates a forward-facing
    duty, is of course powerless to "describe" the class of people as
    to whom that duty will in fact be carried out.
    50 An en banc panel of the Ninth Circuit determined that the
    constitutional avoidance canon "plays no role in the second Chevron
    inquiry." Morales-Izquierdo v. Gonzales, 
    486 F.3d 484
    , 493 (9th
    Cir. 2007) (en banc).     The Tenth Circuit in Olmos cited that
    opinion approvingly, 
    Olmos, 780 F.3d at 1323
    & n.2, but also
    appeared to reject the merits of petitioner's constitutional
    avoidance argument in its step two analysis, 
    id. at 1324.
    As the
    D.C. Circuit has noted (in a case also cited in Olmos), the Supreme
    Court has at least once indicated that the "canon of constitutional
    avoidance trumps Chevron deference."       Nat'l Mining Ass'n v.
    Kempthorne, 
    512 F.3d 702
    , 711 (D.C. Cir. 2008) (citing Edward J.
    - 101 -
    in Rojas from the range of permissible interpretations requiring
    deference.51
    Petitioners' basic claim in favor of applying the canon
    is that a statutory command to detain aliens such as petitioners
    who had peacefully resided in the community for years after their
    release from criminal custody would raise serious constitutional
    due process concerns.   In accepting this claim, the panel opinion
    relied on what seems to us to be a doubly flawed reading of Justice
    Kennedy's concurring opinion in Demore.
    First, the panel viewed Justice Kennedy's concurrence as
    limiting the Demore majority's rationale for upholding section
    1226(c).   See 
    Castañeda, 769 F.3d at 39
    & n.4.   The panel appeared
    to be (erroneously) applying the Supreme Court's Marks principle,
    which instructs that "[w]hen a fragmented Court decides a case and
    no single rationale explaining the result enjoys the assent of
    five Justices, the holding of the Court may be viewed as that
    position taken by those Members who concurred in the judgments on
    DeBartolo Corp. v. Fla. Gulf Coast Bldg. & Constr. Trades Council,
    
    485 U.S. 568
    , 575 (1988)). Since we see no basis for the canon's
    application regardless, we decline to take any position on the
    canon's precise relevance to the Chevron analysis.
    51 The Third and Fourth Circuits did not address the
    constitutional avoidance argument that petitioners press here.
    See Sylvain, 
    714 F.3d 150
    ; Hosh, 
    680 F.3d 375
    . The Second and
    Tenth Circuits rejected it, see Lora, 
    2015 WL 6499951
    , at *9 n.20;
    
    Olmos, 780 F.3d at 1322
    –24, but the Tenth Circuit noted in a
    footnote that "[c]onstitutional considerations could become
    greater when the gap in custody is considerably longer than six
    days."

    430 U.S. 188
    , 193
    (1977) (internal quotation marks omitted).               But Justice Kennedy's
    concurrence   in     Demore    explicitly      stated    that   he    joined       the
    majority's "careful opinion . . . in full," 
    Demore, 538 U.S. at 533
    (Kennedy, J., concurring), so nothing therein limits the
    majority's rationale for upholding section 1226(c).
    Nor    does    Justice      Kennedy's        concurrence           provide
    persuasive    authority       in   favor   of    petitioners'        due       process
    argument.     That concurrence expressed no reservation at all,
    constitutional or otherwise, about the amount of time that passed
    between the moment an alien became released and the moment of the
    alien's detention.        Rather, Justice Kennedy wrote separately to
    address a concern (which we share) about the amount of time an
    alien spends in immigration detention while he waits for his
    removal proceeding.        See 
    id. at 532
    ("[S]ince the Due Process
    Clause   prohibits    arbitrary      deprivations       of   liberty,      a    lawful
    permanent resident alien such as respondent could be entitled to
    an individualized determination as to his risk of flight and
    dangerousness if the continued detention became unreasonable or
    unjustified."      (emphasis       added)).      The     concurrence's           three
    citations to Zadvydas v. Davis, 
    533 U.S. 678
    (2001), a case dealing
    the constitutional limits upon the duration of post-removal-period
    detention (and the only court case cited by the concurrence),
    support that limited reading.
    - 103 -
    To be sure, the Demore majority addressed only the
    general    application    of   section   1226(c)    to   an   alien   who   had
    committed an (A)-(D) offense, without considering the precise
    constitutional consideration--the length of time an alien managed
    to   avoid    detention   post-release--that       petitioners    now   claim
    requires a resolution in their favor.52             But for the following
    reasons, we view this as a distinction without a difference with
    respect to whether the delay in commencing detention experienced
    by petitioners raises constitutional concerns.
    Petitioners' argument rests on the premise that, once a
    law-breaking alien has been out of custody for several years, one
    can no longer regard him as presenting a sufficiently heightened
    risk of danger or flight, even once the alien finds out ICE now
    wants to deport him on grounds that will be hard to successfully
    contest.     Neither petitioners nor the vacated panel opinion cite
    any controlling authority for this proposition, and we have great
    difficulty accepting this view of flight risk as a matter of common
    sense.     See 
    Olmos, 780 F.3d at 1323
    ("[W]e do not abandon Chevron
    deference    at   the   mere   mention   of   a    possible   constitutional
    problem." (alteration in original) (quoting 
    Kempthorne, 512 F.3d at 711
    )).      It seems to us that Congress could have--and did--
    52Perhaps since he was detained the day after his release,
    Kim v. Ziglar, 
    276 F.3d 523
    , 526 (9th Cir. 2002), the petitioner
    in Demore made no argument about the timing of his release.
    - 104 -
    reasonably regard this group of aliens as categorically posing a
    flight risk because their commission of the designated crimes makes
    it highly likely that they will be deported if ICE comes knocking.
    Hence, there is little to lose by trying to hide, especially once
    a   removal    order   issues.   See   S.   Rep.   No.   104-48,   at   2-3
    ("Undetained criminal aliens with deportation orders often abscond
    upon receiving a final notification [of removal]. . . . Too often,
    as one frustrated INS official told the Subcommittee staff, only
    the stupid and honest get deported."). The incentive to flee peaks
    once the criminal alien knows that ICE has decided to come after
    him.    And while the incentive may be depressed while ICE ignores
    the alien, once ICE manifests an intention to proceed forthwith,
    the incentive to flee before the deportation proceeding ends would
    seem to be unrelated to any delay in making that manifestation.53
    The view of petitioners and of the vacated panel opinion
    on this point is effectively that, if there is an individual fact
    showing a person poses a lesser risk of flight or danger (e.g.,
    has been living in a community for years), then that person is
    53
    Imagine Aliens A and B in a detention center, each having
    committed the same section 1226(c) offense, and each similar in
    all ways, except ICE detained Alien A one day after release from
    state custody, and Alien B four years after release. Now imagine
    that each was suddenly released pending completion of his removal
    hearing. We can see no reason why we can say that, as a matter of
    constitutional law, Congress could not have reasonably viewed A
    and B as posing similar flight risks during the period between
    release and removal hearing.

    constitutionally entitled to a bail hearing.                        See 
    Castañeda, 769 F.3d at 47-48
    ("Mandatory detention of individuals such as the
    petitioners           appears    arbitrary     on    its    face.").         This   view
    fundamentally          pushes    back   on    Congress's     ability     (affirmed    in
    Demore) to say categorically that criminal aliens should not have
    the ability to flee while awaiting the reasonably prompt conclusion
    of their deportation hearings.54               We would therefore reject it.
    We    note,     finally,     that   petitioners       have   raised   no
    argument based on the duration of their detention, nor have they
    produced evidence that the BIA's interpretation of section 1226(c)
    will subject them to systemic delays or otherwise prolong the
    length of their detention prior to a hearing.                         Cf. 
    Demore, 538 U.S. at 532
    (Kennedy, J., concurring).                     As of the time that the
    Supreme Court last considered the statute, "in 85% of the cases in
    which        aliens    [were]    detained     pursuant     to   §    1226(c),   removal
    proceedings [were] completed in an average time of 47 days and a
    median of 30 days."             
    Demore, 538 U.S. at 529
    .            To the extent that
    the Attorney General would attempt to use section 1226(c) to detain
    54
    Many statutes and cases in the criminal sentencing area
    give equal weight to prior criminal convictions irrespective of
    whether the individual was recently released from custody.      A
    person qualifies, for example, for mandatory life imprisonment as
    a "violent felon" whether his predicate convictions occurred last
    year or six years ago. See 18 U.S.C. § 3559(c)(1). Accordingly,
    we cannot say that Congress could not regard the danger risk as
    materially reduced merely because the alien has spent some time
    out of custody.

    persons for materially more extended durations, see Lora, 
    2015 WL 6499951
    , at *12, we offer in this opinion no blessing of such
    detentions.     Rather,   we   opine   only    that   the   constitutional
    arguments raised by petitioners here do not make impermissible the
    BIA's interpretation of section 1226(c), either facially or as
    applied to petitioners.
    II.    Conclusion
    For   the   foregoing     reasons,     we    would   hold   that
    petitioners have the characteristics of "an alien described in"
    section 1226(c)(1), and that the Attorney General is correct in
    concluding that she therefore lacks the discretion to grant them
    a bond hearing.55
    55Petitioners do not argue that they qualify for the witness
    protection exception in section 1226(c)(2).
