  •           United States Court of Appeals
    For the First Circuit
    No. 22-1121
    UNITED STATES,
    Appellee,
    v.
    GILBERT PEREZ,
    Defendant, Appellant.
    APPEAL FROM THE UNITED STATES DISTRICT COURT
    FOR THE DISTRICT OF MAINE
    [Hon. D. Brock Hornby, U.S. District Judge]
    Before
    Barron, Chief Judge,
    Howard and Montecalvo, Circuit Judges.
    Jamesa J. Drake, with whom Drake Law LLC was on brief, for
    appellant.
    Brian S. Kleinbord, Assistant United States Attorney, with
    whom Darcie N. McElwee, United States Attorney, was on brief, for
    appellee.
    December 28, 2023
    BARRON, Chief Judge.      Gilbert Perez seeks to vacate his
    federal drug conviction on the ground that the United States
    District Court for the District of Maine wrongly denied his motion
    to suppress the fruits of a warrantless search of his backpack.
    The District Court rested the denial on our decision in United
    States v. Eatherton, 
    519 F.2d 603
     (1st Cir. 1975), which upheld a
    similar warrantless search under the search-incident-to-arrest
    exception to the warrant requirement of the Fourth Amendment to
    the U.S. Constitution, 
    id. at 609-11
    .        Because we reject Perez's
    contention that intervening decisions of the Supreme Court of the
    United States have stripped Eatherton of controlling force, we
    affirm the judgment of conviction.
    I.
    When   reviewing   the    denial   of   a   motion   to   suppress
    evidence, "'we recite the facts as found by the district court,
    consistent with record support,' including the testimony from the
    motion hearing."   United States v. Tom, 
    988 F.3d 95
    , 97 (1st Cir.
    2021) (quoting United States v. Soares, 
    521 F.3d 117
    , 118 (1st
    Cir. 2008) (cleaned up)). Massachusetts State Trooper Jason Conant
    was conducting a patrol on the evening of August 30, 2019, when he
    saw a pickup truck with Maine license plates stop in a McDonald's
    - 2 -
    parking lot in Lawrence, Massachusetts.            The driver was later
    identified as Perez.
    Perez exited the truck, donned a backpack, and walked
    towards a residential area near the parking lot.             Conant became
    suspicious of the out-of-state truck, as well as Perez's behavior,
    and alerted other state troopers in the area to watch for Perez.
    Minutes after Perez left the parking lot, a second
    Massachusetts state trooper, Shawn McIntyre, saw Perez exiting a
    taxi on a nearby street.       McIntyre watched Perez start to walk in
    the direction of the McDonald's where the truck was parked.
    McIntyre stopped the taxi and saw large quantities of
    cash at the feet of the taxi's passenger.          McIntyre then radioed
    Conant, informing him of the cash and the suspicion that Perez had
    participated in a drug transaction with the taxi's passenger.
    Perez,    still   wearing   the   backpack,   returned   to   the
    McDonald's parking lot.       Conant pulled his (unmarked) car into the
    parking lot and exited the car.          Roughly simultaneously, Conant
    began to yell "state police," and Perez began to run from the
    parking lot.    Conant gave chase.
    About twenty yards from the parking lot, Perez tripped
    and fell.   Conant caught up to Perez after his fall and pinned him
    to the ground.       A third state trooper, Ryan Dolan, pulled up in a
    patrol car.
    - 3 -
    Conant removed the backpack from Perez as Dolan was
    handcuffing Perez's hands behind his back.         Dolan then sat Perez
    on the pavement.
    After Perez was handcuffed, Conant placed the backpack
    on Dolan's car and opened and searched the backpack.           Perez was
    not in reaching distance of the backpack when the search of the
    backpack took place.
    Conant discovered fentanyl and cocaine in the backpack.
    Perez was then searched and formally arrested.
    Perez was indicted on March 12, 2020, on a federal
    drug-related charge.       He moved to suppress the drugs, contending
    that the backpack's search violated the Fourth Amendment.1
    The government opposed the motion on the ground that the
    search was constitutional under Eatherton.         The government also
    argued that, in any event, the search was conducted in good-faith
    reliance on Eatherton.      See Davis v. United States, 
    564 U.S. 229
    ,
    232   (2011)    (holding    that   "[police]   searches    conducted   in
    objectively reasonable reliance on binding appellate precedent are
    not subject to the exclusionary rule").
    The    District    Court   denied    Perez's    motion   without
    reaching the good-faith issue.       See United States v. Perez, Crim.
    No. 2:20-CR-39-DBH-01, 
    2021 WL 2953671
     (D. Me. July 14, 2021).
    1Perez challenged several other aspects of his arrest in the
    District Court but raises none of those issues on appeal.
    - 4 -
    The District Court found that "[t]he police had probable cause to
    arrest Perez when they handcuffed him," and it "treat[ed] [the
    police] as having effectively arrested him then," although the
    District Court also found that it was only later that Perez was
    "formally" arrested.   Id. at *2.     The District Court separately
    found, moreover, that Perez's handcuffing occurred "as" Conan
    "ripped the backpack off" of Perez.        Id.   With that factual
    predicate in place, the District Court reasoned that the search of
    the backpack was lawful because, when there is probable cause for
    an arrest, Eatherton allows for the warrantless "search [of] a
    container found on a person being arrested," id. at *3, and our
    Court had not "'unmistakably' cast Eatherton 'into disrepute,'"
    id. at *4 (quoting Eulitt ex rel. Eulitt v. Me., Dep’t of Educ.,
    
    386 F.3d 344
    , 349 (1st Cir. 2004)).
    Perez entered a conditional guilty plea, which preserved
    his right to appeal his conviction based on the District Court's
    Eatherton-based denial of his motion to suppress.     He then filed
    this timely appeal.    We review the District Court's "factual
    findings for 'clear error'" and its "legal conclusions . . . de
    novo."   United States v. Rodríguez-Pacheco, 
    948 F.3d 1
    , 6 (1st
    Cir. 2020) (quoting United States v. Camacho, 
    661 F.3d 718
    , 723-
    24 (1st Cir. 2011)).

    II.
    The Fourth Amendment protects "[t]he right of the people
    to be secure in their persons, houses, papers, and effects, against
    unreasonable       searches      and    seizures"       by    providing      that
    "no Warrants shall issue, but upon probable cause."                   U.S. Const.
    amend. IV.    Our focus is on the exception to the Fourth Amendment's
    warrant requirement for a search incident to an arrest. See United
    States v. Robinson, 
    414 U.S. 218
     (1973).
    Perez does not dispute that the exception covers his
    backpack's search if Eatherton remains good law.              He contends only
    that   Eatherton    does   not    because      of   either   United    States   v.
    Chadwick, 
    433 U.S. 1
     (1977), or Arizona v. Gant, 
    556 U.S. 332
    (2009), or both together.
    Under the law of the circuit doctrine, newly constituted
    panels must follow the rulings of preceding panels that are
    "directly (or even closely) on point," United States v. Guzman,
    
    419 F.3d 27
    , 31 (1st Cir. 2005), "even where the succeeding panel
    disagrees with the prior one," United States v. Guerrero, 
    19 F.4th 547
    , 552 (1st. Cir 2021).         The doctrine recognizes an exception,
    however, when "[a]n existing panel decision [is] undermined by
    controlling authority, subsequently announced, such as an opinion
    of the Supreme Court, an en banc opinion of the circuit court, or
    a statutory overruling," Williams v. Ashland Eng'g Co., 
    45 F.3d 588
    , 592 (1st Cir. 1995), or when an "authority that postdates the
    - 6 -
    original decision, although not directly controlling, nevertheless
    offers a sound reason for believing that the former panel, in light
    of fresh developments, would change its collective mind," United
    States v. Barbosa, 
    896 F.3d 60
    , 74 (1st Cir. 2018) (quoting
    Williams, 
    45 F.3d at 592
    ).
    The latter exception is very limited, as it applies only
    when the new authority "provides a clear and convincing basis" to
    conclude    that    the   prior   panel    would    have   changed   its   mind.
    Guerrero, 19 F.4th at 552.          For that reason, we have described
    cases that trigger this exception as "hen's-teeth-rare."               San Juan
    Cable LLC v. P.R. Tel. Co., 
    612 F.3d 25
    , 33 (1st Cir. 2010).
    We    begin   by   reviewing   Eatherton       and   describing   its
    rationale.       We then explain why we conclude that Eatherton still
    controls.
    A.
    The defendant in Eatherton was Gilbert Eatherton.                 519
    F.2d. at 605.        A suspected bank robber, he was walking down a
    street while carrying a briefcase when agents of the Federal Bureau
    of Investigation ("FBI") spotted him.              Id. at 609.
    The FBI agents called for Eatherton to come to their
    car, and he did so.        Id.    When he was "close to the vehicle the
    agents told him he was under arrest [and] instructed him to drop
    the briefcase and [lie] spread eagle on the ground."                    Id.    He
    complied with the commands, and the FBI agents "thoroughly frisked"
    - 7 -
    him, handcuffed him, and placed him in the back of their vehicle.
    Id.    The FBI agents then picked up the briefcase, opened it, and
    found a loaded gun and three brown ski masks, all of which were
    later admitted as evidence at trial.     Id.
    Eatherton did not dispute that there was probable cause
    to arrest him, and he "concede[d] that the agents could have seized
    the briefcase consonant with the [F]ourth [A]mendment."      Id. at
    610.   But he argued that the agents "should have obtained a search
    warrant before investigating [the briefcase's] contents," and
    that, because the agents did not, the search of his briefcase
    violated the Fourth Amendment.    Id. He thus argued that the fruits
    of the search of the briefcase had to be suppressed because that
    search could not be justified merely by the fact of his arrest and
    the right to search his person that his arrest entailed.    Id.
    Eatherton relied chiefly on the Supreme Court's decision
    in Chimel v. California, 
    395 U.S. 752
     (1969).      There, the Court
    held that the bare fact that an arrest occurred inside a home did
    not justify a warrantless search of the entirety of the premises.
    
    Id. at 763
    . The Court also held that although a warrantless search
    of the area of the home within the "immediate control" of the
    arrestee was reasonable if justified "by the need to seize weapons
    and other things which might be used to assault an officer or
    effect an escape" or "by the need to prevent the destruction of
    evidence of the crime," these "justifications are absent where a
    - 8 -
    search is remote in time or place from the arrest."      
    Id. at 764
    (quoting Preston v. United States, 
    376 U.S. 364
    , 367 (1964)).
    Eatherton argued based on Chimel that the briefcase's
    search violated the Fourth Amendment because "any urgency to
    inspect the interior of the briefcase was completely removed once
    he had been subdued and the [brief]case removed from his possession
    and beyond his possible reach."    Eatherton, 
    519 F.2d at 610
    .   But,
    although the Eatherton panel acknowledged that there was "some
    logical cogency" to the contention, 
    id.,
     the panel held that the
    search of the briefcase's interior was reasonable.
    The Eatherton panel first pointed out that Chimel had
    cited "with apparent approval Draper v. United States, in which a
    search virtually identical to that at issue [in Eatherton] was
    upheld."   
    Id.
     (citation omitted).       Draper involved a criminal
    defendant who had evidence admitted against him at his trial that
    was obtained from the warrantless search of a bag that he was
    carrying when he was arrested.    
    358 U.S. 307
    , 310 (1959).
    The Eatherton panel next explained that other courts of
    appeals "had little apparent difficulty" rejecting Chimel-based
    arguments for prohibiting warrantless "searches identical to that
    contested" by Eatherton.   
    519 F.2d at 610
    .     Notably, in each of
    those cases, as in Draper, the warrantlessly-searched container
    was similar in size to the briefcase in Eatherton.       See United
    States v. Maynard, 
    439 F.2d 1086
    , 1087 (9th Cir. 1971) (rejecting
    - 9 -
    the argument that a warrantless search of a suitcase the defendant
    was carrying when arrested was unconstitutional because the search
    was "incident to the lawful arrest of its carrier"); United States
    v. Mehciz, 
    437 F.2d 145
    , 146-48 (9th Cir. 1971) (relying on Draper
    to reject the contention that Chimel governed a warrantless search
    of a suitcase carried at the time of arrest); United States ex
    rel. Muhammad v. Mancusi, 
    432 F.2d 1046
    , 1047-48 (2d Cir. 1970)
    (rejecting     as   "frivolous"   a   Chimel-based   challenge   to   the
    post-arrest search at a police station of a briefcase in the
    "immediate possession" of the defendant at the time of the arrest
    when the defendant conceded that the search "would have been proper
    if [it] had been conducted at the time [and place] of his arrest").
    The Eatherton panel then addressed three Supreme Court
    decisions that post-dated both Chimel and the other circuits'
    rulings that had upheld searches like the search of Eatherton's
    briefcase: Robinson, 
    414 U.S. at 218
    ; Gustafson v. Florida, 
    414 U.S. 260
     (1973); and United States v. Edwards, 
    415 U.S. 800
     (1974).
    The Eatherton panel explained that this trio showed that the
    Chimel-based challenge could not "be sustained."         Eatherton, 
    519 F.2d at 610
    .
    In Robinson, the Court held that the warrantless search
    of a "crumpled up cigarette package" found in the "breast pocket
    of the heavy coat [the arrestee] was wearing" at the time of his
    arrest did not violate the Fourth Amendment, even though the
    - 10 -
    arresting   officer    had   neither    "any     subjective   fear   of   the
    [arrestee]" or any "susp[icion] that the [arrestee] was armed."
    414 U.S. at 222-23, 236.         The Court explained that because the
    "custodial arrest of a suspect based on probable cause is a
    reasonable intrusion under the Fourth Amendment[,]" a search "of
    the person" of an arrestee incident to that arrest is per se
    reasonable.    Id. at 235.     Robinson thus rejected the contention
    that a more limited pat-down -- such as the limited frisk permitted
    in Terry v. Ohio, 
    392 U.S. 1
     (1968) -- was all that was allowed
    for a search incident to the arrest.             See Robinson, 
    414 U.S. at 235
    .   And the Court then explained that "[h]aving in the course of
    a lawful search come upon the crumpled package of cigarettes, [the
    officer who had conducted the search of the arrestee's person] was
    entitled to inspect [the package,] and when his inspection revealed
    the heroin capsules, he was entitled to seize them as 'fruits,
    instrumentalities, or contraband' probative of criminal conduct."
    
    Id. at 236
     (quoting Harris v. United States, 
    331 U.S. 145
    , 154-55
    (1947)).
    Robinson    relied     on      the     rationales    for      the
    search-incident-to-arrest exception to the warrant requirement to
    justify the ruling that the warrantless search of the cigarette
    package was reasonable.      Those rationales are rooted in a concern
    for officer safety, the governmental interest in the preservation
    of evidence, and the diminished privacy interest of an arrestee
    - 11 -
    due to the dominion over their person effected by the arrest
    itself.     See   Robinson,    
    414 U.S. at 226
    ;    see     also    Riley   v.
    California, 
    573 U.S. 373
    , 386 (2014) ("Robinson regarded any
    privacy   interests     retained     by   an   individual           after    arrest   as
    significantly diminished by the fact of the arrest itself.").
    In Gustafson, which was decided the same day as Robinson,
    the Court went a step further than it had in Robinson.                         It held
    that a warrantless search of a cigarette box found in the "front
    coat pocket of the coat [the arrestee] was wearing" during a search
    of the arrestee's person at the time of his arrest, 414 U.S. at
    262, was per se reasonable under Robinson even though the search
    of the cigarette box occurred after the arrestee had been placed
    "in the back seat of the squad car," id. at 262 n.2, and even
    though    there   was   no   "subjective       fear    of     the    [arrestee]"      or
    "susp[icion] that the [arrestee] was armed," id. at 266.
    The defendant in Eatherton tried to distinguish Robinson
    and Gustafson based on the relatively large size of his briefcase
    and the fact that it was not concealed in his pocket but held in
    his hand at the time of the arrest.                   But the Eatherton panel
    concluded that "[t]he line which [Eatherton] attempts to draw
    placing the briefcase beyond the search of his 'person' which
    Robinson and Gustafson expressly approve is one requiring gossamer
    distinctions."     Eatherton, 
    519 F.2d at 610
    .               And Eatherton went on
    to state that "[t]here is no indication that the result in those
    - 12 -
    cases would have been any different had the cigarette packages
    been in the defendants' hands rather than in their pockets or if
    they had been dropped to the ground in response to [a] police
    command." 
    Id.
     Moreover, Eatherton explained, "[w]hile a briefcase
    may be a different order of container than a cigarette box, it is
    not easy to rest a principled articulation of the reach of the
    [F]ourth [A]mendment upon the distinction."               
    Id.
    The Eatherton panel also noted that the defendant's
    argument was "not unlike" Justice Marshall's in "his dissent to
    Gustafson and Robinson."        
    Id.
         The Eatherton panel then cited to
    the portion of that dissent that relied on Chimel to dispute the
    majority's     decision   to   uphold    the   warrantless       search   of   the
    container in that case.        
    Id.
     (citing Robinson, 
    414 U.S. at 256-58
    (Marshall, J., dissenting)).          While the argument advanced in that
    portion   of    Justice   Marshall's      dissent    "may       have   analytical
    appeal," the Eatherton panel concluded, the view set forth there
    "does not presently represent the law."             
    Id.
    The Eatherton panel wound up its analysis by invoking
    Edwards, which was decided the year after Robinson and Gustafson.
    The Court held in Edwards that the Fourth Amendment permitted the
    warrantless search of clothing that an arrestee was wearing at the
    time of his arrest even though the search of the clothing occurred
    the day after the arrest and while the arrestee was in jail.
    Edwards, 
    415 U.S. at 808-09
    .            Edwards reasoned that "the legal
    - 13 -
    arrest of a person" reduces the arrestee's expectation of privacy
    in items "in his immediate possession, including his clothing."
    
    Id. at 805, 808
     (emphasis added) (quoting United States v. DeLeo,
    
    422 F.2d 487
    , 493 (1st Cir. 1970)).
    The Eatherton panel observed that the Court in Edwards,
    "after noting that the courts of appeals have generally permitted
    searches of both 'the person and the property in his immediate
    possession,'" stated that "it is difficult to perceive what is
    unreasonable about the police examining and holding as evidence
    those personal effects of the accused that they already have in
    their lawful custody as the result of a lawful arrest." Eatherton,
    
    519 F.2d at 610
     (first quoting Edwards, 
    415 U.S. at 803
    ; then
    quoting Edwards, 
    415 U.S. at 806
    ).       The search in Edwards had been
    made   "in    the     station   house   after   an   arrest,"   Eatherton
    acknowledged.       But Eatherton explained that there was no reason to
    "doubt that [those observations from Edwards] apply equally to
    searches in the field immediately incident to the arrest."            
    Id.
    Eatherton thus held that, as the defendant in the case before it
    had "conceded the agents properly seized the briefcase as . . .
    incident to his arrest . . . any expectation of privacy which he
    held with regard to the briefcase was taken out of 'the realm of
    protection from police interest in weapons, means of escape, and
    evidence.'"    Id. at 610-11 (quoting Edwards, 
    415 U.S. at 808-09
    ).
    - 14 -
    B.
    As this extended review of Eatherton reveals, the panel
    in that case did more than determine that the rule set forth in
    Robinson, Gustafson, and Edwards rather than the rule set forth in
    Chimel controlled the briefcase's search.              The panel also made
    clear that it based that determination on the considered judgment
    that, for purposes of the rule laid down in Robinson and Gustafson,
    a search of a container (at least of the "order" of a briefcase,
    see Eatherton, 
    519 F.2d at 610
    ) in the hands of an arrestee at the
    time of the arrest was no different from a search of a container
    in the pocket of an arrestee at that time.2            As Eatherton put it,
    a "line which [would] plac[e] the briefcase beyond the search of
    [the] 'person' which Robinson and Gustafson expressly approve is
    one requiring gossamer distinctions."             
    519 F.2d at 610
    .    And, to
    that       point,   the   Eatherton   panel    explained   that,   although   a
    briefcase was of "a different order of container from a cigarette
    box," it would not be "easy" to make any such distinction for the
    2We understand Eatherton's statement that "[t]here is no
    indication that the result in [Robinson and Gustafson] would have
    been any different had the cigarette packages been . . . dropped
    to the ground in response to police command," 
    519 F.2d at 610
    , to
    mean only that the determination of whether an item is "of the
    person" of the arrestee or in the arrestee's "area of immediate
    control" is unaffected by post-arrest, police-ordered conduct.
    After all, at the same time that the FBI agents told Eatherton to
    drop the briefcase, they also told him he was under arrest.

    relevant Fourth Amendment purposes in a "principled" manner.                 
    Id.
    Eatherton then reasoned that, as a result, Edwards required the
    conclusion that the briefcase's search was reasonable, given that
    Edwards concluded that the search of the personal property found
    on the person of the arrestee in that case was reasonable.                   In
    that regard, Eatherton concluded based on Edwards that because
    "the   agents   properly   seized    the     briefcase   . . .    incident   to
    [Eatherton's] arrest. . . . any expectation of privacy which he
    held with regard to the briefcase was taken out of 'the realm of
    protection from police interest in weapons, means of escape, and
    evidence.'"     
    Id. at 610-11
     (quoting Edwards, 
    415 U.S. at 808-09
    ).
    Perez   does    not   suggest     that   there   is   any   relevant
    difference between his backpack and the briefcase in Eatherton or
    that the backpack was not on his back when the District Court found
    that he was arrested, notwithstanding that the District Court found
    that he was "formally" arrested only thereafter.             He thus accepts
    that his appeal lacks merit if Eatherton controls.                     His sole
    contention, therefore, is that Eatherton does not control due to
    post-Eatherton developments.
    C.
    The post-Eatherton developments that Perez has in mind
    are two Supreme Court precedents: Chadwick and Gant.              He contends
    that, whether separately or together, they undermine (even if they
    do not overrule) Eatherton's holding that a briefcase in the hands
    - 16 -
    of an arrestee at the time of arrest is no different from the
    cigarette containers involved in Robinson and Gustafson.                   But we
    cannot agree -- even if we account for post-Chadwick and post-Gant
    out-of-circuit precedent that is at odds with Eatherton.                  Thus, we
    conclude that Eatherton remains binding on us as a panel.3
    1.
    We start with Perez's arguments about Chadwick, which
    was decided two years after               Eatherton.       Perez contends that
    Chadwick       is    a    significant       intervening     precedent     because
    Eatherton's rationale depended on the determination that there was
    "no indication" that the result in either Robinson or Gustafson
    "would have been any different had the cigarette packages been in
    the defendants' hands rather than in their pockets or if they had
    been       dropped   to   the   ground    in    response   to   police   command."
    Eatherton, 
    519 F.2d at 610
    .              Yet, Perez asserts, Chadwick shows
    that is not so.
    Neither Perez nor the government addresses whether, even if
    3
    Eatherton does not control the outcome of this case, it is
    controlled by our post-Chadwick ruling in United States v.
    Maldonaldo-Espinosa, 
    968 F.2d 101
    , 104 (1st Cir. 1992) (rejecting
    an argument that the search of a bag "on the table next to [the
    handcuffed defendant] and within reach" could be justified only by
    an exigency because "government agents, when arresting a person,
    may constitutionally search an arrested person's nearby . . . bag,
    without a warrant . . . whether or not [the agents] have reason to
    fear that the carry-on bag contains a weapon, another threat to
    their safety, or destructible evidence"). Because we conclude that
    Eatherton controls here, we need not evaluate the search of Perez's
    backpack under Maldonaldo-Espinosa.
    - 17 -
    The Supreme Court held in Chadwick that the warrantless
    search of an arrestee's      "double-locked,    200-pound footlocker"
    violated the Fourth Amendment when the search of that container
    was conducted beyond "the area from within which [the arrestees]
    might gain possession of a weapon or destructible evidence,"
    Chadwick, 
    433 U.S. at 5
     (quoting Chimel, 
    395 U.S. at 763
    ), and was
    not "justified by any other exigency," id. at 15.         But nothing in
    Chadwick   disturbs    either    Robinson's    ruling     upholding    the
    warrantless search of a cigarette container in the pocket of an
    arrestee at the time of the lawful arrest or Gustafson's ruling
    upholding such a search even when it is performed after the
    cigarette container has been removed from the arrestee's immediate
    area of control.
    In   that   regard,   Chadwick     expressly    states     that,
    "[u]nlike searches of the person [under] United States v. Robinson
    [and] United States v. Edwards, searches of possessions within an
    arrestee's immediate control cannot be justified by any reduced
    expectations of privacy caused by the arrest."            
    433 U.S. at
    16
    n.10 (emphasis added) (citations omitted).        We do not read that
    passage, in expressly reaffirming Robinson and Edwards, to be
    silently rejecting the parts of their holdings that blessed the
    searches of the personal property in those cases that was found on
    the person of the defendants.      Nor do we read that passage, in
    reaffirming those two cases without mentioning Gustafson, to be
    - 18 -
    silently    rejecting      Gustafson's     extension    of   Robinson's    rule
    regarding a search of personal property on the person of the
    arrestee at the time of the arrest to cover the search of such
    property even after that property was no longer in the arrestee's
    area of immediate control.
    Moreover, nothing in Chadwick purports to address how to
    treat a container that an arrestee has in hand at the time of
    arrest relative to a container that an arrestee has in a pocket at
    that time.      In fact, Chadwick had no reason to address that
    question because the arrestee was not holding the container in
    Chadwick.    Nor, for that same reason, did Chadwick have reason to
    address whether the arrestee's dropping of such a container in
    response to a police command upon arrest would change the calculus.
    So, not surprisingly, Chadwick does not purport to address that
    scenario either.
    True, Chadwick does state that "[o]nce law enforcement
    officers have reduced luggage or other personal property not
    immediately associated with the person of the arrestee to their
    exclusive control, and there is no longer any danger that the
    arrestee might gain access to the property to seize a weapon or
    destroy evidence, a search of the property is no longer an incident
    of the arrest."         
    433 U.S. at 15
     (emphasis added).             But the
    emphasized    language     shows   that    Chadwick's   "immediate   area    of
    control"     rule   does    not    apply   to   "personal    property     . . .
    - 19 -
    immediately associated with the person of the arrestee," 
    id.,
     and
    so merely operates in parallel to the holdings in                           Robinson,
    Gustafson, and Edwards.          Thus, because Chadwick does not address
    what, if any, personal property carried or worn by the arrestee at
    the time of the arrest beyond the cigarette packages in Robinson
    and Gustafson and the clothing in Edwards constitutes "personal
    property     . . . immediately         associated   with   the      person    of   the
    arrestee," Chadwick does not address whether a held briefcase like
    the one in Eatherton is to be treated the way that the personal
    property in those three cases was.           As a result, Chadwick gives no
    "indication that the result in [Robinson and Gustafson] would have
    been   any    different    had    the    cigarette     packages      been     in   the
    defendants' hands rather than in their pockets or if they had been
    dropped to the ground in response to police command."                    Eatherton,
    
    519 F.2d at 610
    .
    Simply     put,   Eatherton     was    concerned       about     drawing
    distinctions     between       types    of   containers       in    an   arrestee's
    "immediate     possession,"      Eatherton,      
    519 F.2d at 610
         (quoting
    Edwards, 415 at 803), at the time of arrest -- a problem that is
    hardly trivial given the range of containers people may carry
    beyond cigarette packages, from holsters to purses to backpacks.
    But, as      Chadwick    had no reason to address that line-drawing
    problem, it cannot offer any insight into how to resolve that
    - 20 -
    problem.    We thus do not see how Chadwick undermines Eatherton's
    rationale for upholding the search of the briefcase in Eatherton.
    2.
    Perez does argue that Gant undermines Eatherton even if
    Chadwick does not.   But here, too, we disagree.
    Gant relied on Chimel in holding that courts had wrongly
    interpreted New York v. Belton, 
    453 U.S. 454
     (1981), to have held
    that all personal property in an automobile was categorically
    searchable incident to an occupant's arrest.       Gant, 
    556 U.S. at 348-52
    .    Perez contends that it follows from Gant that the search
    of his backpack is no different from the car search in that case.
    But, Gant, like Chadwick, said nothing about whether the
    rule of Robinson (as applied in Gustafson and Edwards) governs a
    container that an arrestee is carrying at the time of the arrest
    (or that is dropped in response to police command at that time).
    Indeed, Gant did not address carried personal property at all,
    because it concerned only whether a car may be searched incident
    to a lawful arrest of an occupant of the car.       Thus, Gant is no
    different from Chadwick in the relevant respect, and so provides
    no basis for our concluding that Eatherton has been stripped of
    its controlling force.     For, like Chadwick, Gant has literally
    nothing to say about where the line should be drawn in searches
    - 21 -
    incident to arrest when it comes to things an arrestee carries at
    the time of the arrest.4
    D.
    The dissent appears to accept that neither Chadwick nor
    Gant       directly   overrules   Eatherton.     The   dissent    nonetheless
    contends that we still can be confident that if the panel in
    Eatherton knew what we do in consequence of Chadwick and Gant,
    that panel would have abandoned its hard line about the difficulty
    of drawing hard lines.        As the dissent sees it, the panel in that
    event would have "centered its analysis around 'immediate control'
    rather than shoehorning the search of a closed container into being
    'of the [arrestee's] person.'"             Dissent at 49.   But we see no
    "clear and convincing" case for that conclusion.                 Guerrero, 19
    F.4th at 552.
    Chadwick does make clear that no per se rule establishes
    that "luggage" within the "immediate area of control" of an
    Perez does at points argue that, under Gant, the location
    4
    of a container "relative to the arrestee at the time of arrest is
    irrelevant" when determining whether the container can be searched
    without a warrant, because all such searches should be evaluated
    based on the container's location at the time of its search. But,
    as Gustafson and Edwards show, the application of Robinson's
    categorical rule depends, as to at least some personal property,
    on the property's location at the time of the arrest and not at
    the time of the search.      And, as we have explained, there is
    nothing in Gant that undermines Robinson, Gustafson, or Edwards.
    We thus do not see how Perez's time-of-the-search contention,
    insofar as it is meant to address all containers, can be reconciled
    with Robinson as it was applied in Gustafson and Edwards.
    - 22 -
    arrestee at the time of the arrest may be warrantlessly searched.
    See Chadwick, 
    433 U.S. at
    16 n.10.          Thus, Chadwick does prompt the
    question of why it would be per se reasonable to search a briefcase
    that is held (or dropped upon police command) by an arrestee at
    the time of the arrest.
    But Chadwick applied the "immediate control" test to a
    container that was not carried by the arrestee at the time of the
    arrest.      By contrast, the Eatherton panel was addressing only how
    to treat a container that an arrestee was carrying at that time,
    so the Eatherton panel did not purport to suggest that the Robinson
    rule would apply to nearby containers not carried by the arrestee
    at the time of the arrest.        As a result, Chadwick fails to provide
    a clear and convincing reason for us to conclude that the Eatherton
    panel would have reversed course had it known about Chadwick.
    That is especially so given that Chadwick, in a passage
    that   the    dissent     mentions    but   otherwise    ignores,   expressly
    distinguishes       searches     of    personal    property     "immediately
    associated" with the person of the arrestee (like the personal
    property     at   issue   in   Robinson,    Gustafson,   and   Edwards)   from
    searches of personal property of the arrestee that is merely within
    the "immediate control" of the arrestee.          
    Id. at 15
    .    For, because
    of that distinction, Chadwick did not address whether principled
    lines could be drawn in this context between types of containers
    that are carried by the arrestee at the time of arrest -- whether
    - 23 -
    those types of containers are cigarette packs, wallets, purses,
    fanny packs, holsters, or briefcases.                      Yet Eatherton's clearly
    expressed concern was that such lines could not be drawn.                              See
    Eatherton, 
    519 F.2d at 610
    .
    Gant   similarly     offers        no    relevant    insight     into    the
    proper way to resolve the line-drawing problem that troubled the
    Eatherton      panel.        Because      Gant     addresses      only    searches      of
    automobiles, it says nothing about what distinctions might be
    tenable when it comes to containers that an arrestee is carrying
    at the time of the arrest.
    We thus fail to see how we could be confident that
    Chadwick or Gant -- or even the two taken together -- would have
    led the Eatherton panel to "center" its analysis of the briefcase
    on the "immediate control" question.                   Were the panel to have done
    so, it would have been forced to draw the very distinctions between
    the   types    of    carried    containers         that    it    concluded     were    too
    "gossamer" to make.          Eatherton, 
    519 F.2d at 610
    .                But not a word
    in either Chadwick or Gant would give the Eatherton panel reason
    to    think   that,     contrary     to    the        panel's   initial    assessment,
    distinctions of substance as to such containers could be made in
    a "principled" manner.          See 
    id.
    Of course, the dissent is right that, in the wake of
    Chadwick      and    Gant,   other     circuits         have    drawn    the   kinds   of
    distinctions that Eatherton refused to make.                    See United States v.
    - 24 -
    Knapp, 
    917 F.3d 1161
    , 1168 (10th Cir. 2019) (holding that the
    search of a purse was governed by the Chimel standard because the
    purse   "was    not   concealed   under   or     within   [the    defendant's]
    clothing" and "was easily capable of separation from her person");
    United States v. Shakir, 
    616 F.3d 315
    , 321 (3rd Cir. 2010) ("[A]
    search is permissible incident to a suspect's arrest when, under
    all the circumstances, there remains a reasonable possibility that
    the arrestee could access a weapon or destructible evidence in the
    container or area being searched.").         But post-Eatherton precedent
    is not uniformly at odds with Eatherton, as even the dissent
    acknowledges     in   describing    how     other      circuits   reacted   to
    Chadwick -- at least prior to Gant.          See Dissent at 39.
    Indeed, some circuits after Chadwick but before Gant
    appeared   to   follow   Eatherton's      lead    in   categorizing   certain
    carried items as "of the person."           Two months after Chadwick was
    decided, for example, the Fourth Circuit assumed that warrantless
    searches of objects carried in an arrestee's hands were permissible
    as searches "of the person incidental to an arrest." United States
    v. Wyatt, 
    561 F.2d 1388
    , 1391 (4th Cir. 1977) (search of a notebook
    that arrestee retrieved from his car after being arrested).                 And
    four years later, in United States v. Graham, the Seventh Circuit
    explained that a "shoulder purse carried by a person at the time
    he is stopped lies within the scope of a warrant authorizing the
    search of his person."      
    638 F.2d 1111
    , 1114 (7th Cir. 1981).
    - 25 -
    Although the question in Graham was whether the purse
    was "of the person" for purposes of a search warrant authorizing
    a search of the person, and there was no issue of a warrantless
    search incident to an arrest, the Seventh Circuit's reasoning
    nevertheless aligns neatly with Eatherton's.         As the Seventh
    Circuit explained, "[c]ontainers . . . while appended to the body,
    are so closely associated with the person that they are identified
    with and included within the concept of one's person.           To hold
    differently would be to narrow the scope of a search of one's
    person to a point at which it would have little meaning."           
    Id.
    And almost two decades later, the Eighth Circuit followed the
    Seventh Circuit's lead and explained that a purse, for purposes of
    the       search-incident-to-arrest   exception,   was     an    object
    "immediately associated" with one's person, even though the purse
    in that case was also within the arrestee's area of "immediate
    control."      Curd v. City Court, 
    141 F.3d 839
    , 843-44 (8th Cir.
    1998).     Indeed, the Eighth Circuit agreed "with the general view"
    of other courts that "concluded that a purse, like a wallet, is an
    object 'immediately associated' with the person."        
    Id.
     (citations
    omitted).5
    5To be sure, four months later, the Eighth Circuit approved
    a backpack search because "the search of his person and backpack
    was lawful as a search incident to arrest," seemingly
    distinguishing "person" from "backpack" and citing a case for the
    idea that possessions within "immediate control" can be searched.
    United States v. Oakley, 
    153 F.3d 696
    , 698 (8th Cir. 1998).
    - 26 -
    Thus, to the extent that post-Chadwick precedents from
    sister circuits may shed light on what the Eatherton panel would
    have done with the benefit of them, we do not see how the pre-Gant
    precedents of that ilk do. Even though some of those post-Chadwick
    but   pre-Gant   precedents   adopt    the   dissent's    position,    these
    precedents are, as a group, too varied to justify application of
    the second exception to the law-of-the-circuit doctrine.
    The dissent does also cite to post-Gant sister-circuit
    cases that extend Gant to non-vehicle contexts.          See, e.g., United
    States v. Davis, 
    997 F.3d 191
    , 193 (4th Cir. 2021) ("Gant applies
    beyond the automobile context to the search of a backpack.");
    United States v. Knapp, 
    917 F.3d 1161
    , 1168 (10th Cir. 2019)
    ("[A]lthough     Gant   specifically    addressed   the    search     of   an
    automobile, its principles apply more broadly."); United States v.
    Cook, 
    808 F.3d 1195
    , 1199 n.1 (9th Cir. 2015) ("We do not read
    Gant's holding as limited only to automobile searches because the
    Court tethered its rational to the concerns articulated in Chimel,
    which involved a search of an arrestee's home."); Shakir, 
    616 F.3d at 318
     ("[T]he Government contends that the rule of Gant applies
    only to vehicle searches.       We do not read Gant so narrowly.").
    But these out-of-circuit cases also fail to show what is required
    to justify applying the second exception to the law-of-the-circuit
    doctrine.
    - 27 -
    Even after Gant, the Supreme Court recognized in Riley
    v. California that "[l]ower courts applying Robinson and Chimel
    . . . have approved searches of a variety of personal items carried
    by an arrestee" and cited to a case where the D.C. Circuit upheld
    the search of a purse incident to the arrest of its owner.             
    573 U.S. 373
    , 392-93 (2014) (citing, inter alia, United States v. Lee,
    
    501 F.2d 890
    ,   892   (D.C.   Cir.   1974)).   And   Riley   repeatedly
    described Gant as a case involving automobile searches without in
    any way suggesting that Gant had worked a reformation of Robinson's
    rule for searches of at least some personal property on the person
    of the arrestee at the time of the arrest.           See 573 U.S. at 398
    ("But Gant relied on 'circumstances unique to the vehicle context'"
    (quoting Gant, 
    556 U.S. at 343
    )); 
    id. at 385
     ("Gant added . . . an
    independent exception for a warrantless search of a vehicle's
    passenger compartment . . . . That exception stems not from Chimel
    . . . but from 'circumstances unique to the vehicle context.'"
    (quoting Gant, 
    556 U.S. at 343
    )).         Thus, the post-Gant cases from
    sister circuits do not show in a clear and convincing way that the
    Eatherton panel -- with the benefit of Gant -- would have ruled
    the same way that those circuits had.
    We note, too, that Riley made its observation about how
    other circuits had applied Robinson post-Chadwick while addressing
    whether the rule of Robinson extends to the search of the data on
    an arrestee's carried cellphone.         Riley, 573 U.S. at 392-93.   Yet,
    - 28 -
    in doing so, the Court both expressly reaffirmed that Robinson
    survived Chadwick as to at least some personal property on the
    person of the arrestee at the time of arrest, id. at 384, 394, and
    highlighted the fact that Chadwick expressly exempted from its
    "immediate control" test "personal property . . . immediately
    associated with the person of the arrestee[,]" id. at 384 (first
    alteration in original) (quoting Chadwick, 
    433 U.S. at 15
    ).
    Finally, although Riley carefully explained that the
    officer-safety,     evidence-collection,       and     diminished-privacy
    rationales for Robinson's rule did not apply to a cell phone's
    data, the Court said nothing in doing so that "clear[ly] and
    convincing[ly]"    indicates,    Guerrero,    19     F.4th   at   552,   that
    Robinson's rule has no application to a container that is of the
    same "order" as a briefcase, Eatherton, 
    519 F.2d at 610
    .                 Riley
    does   suggest   that,   based   on   those   rationales,     a   200-pound
    double-locked storage trunk may fall outside Robinson's rule even
    if the arrestee happens to be dragging the trunk along behind him.
    See Riley, 573 U.S. at 394.      But Eatherton did not itself suggest
    otherwise.   Rather, Eatherton held only that a briefcase that the
    arrestee was carrying at the time of the arrest fell within
    Robinson's rule because the distinction between such a container
    when held in hand and a cigarette package when carried in a pocket
    was "gossamer" and because it was "not easy to rest a principled
    - 29 -
    articulation of the reach of the [F]ourth [A]mendment upon the
    distinction."       Eatherton, 
    519 F.2d at 610
    .
    We note, too, that Riley's comment about the potential
    exclusion of the dragged trunk from Robinson's rule was based on
    the   notion      that   "[m]ost      people     cannot   lug     around"     a    trunk
    containing "every piece of mail . . . every picture . . . or every
    book or article they have read" and on the observation that "nor
    would they have any reason to attempt to do so."                    Id. at 393-94.
    Yet, of course, most people can carry a briefcase and often have
    reason to do so.         Indeed, Perez himself does not argue that Riley
    is the case that would have led the Eatherton panel to rule other
    than it did, as he contends only that Riley merely excluded digital
    content from Robinson's rule.
    E.
    We close by addressing what may be our key point of
    disagreement with our dissenting colleague -- the proper scope of
    the second exception to the law-of-the-circuit doctrine.                          As we
    see   it,   the    whole   point      of   the   doctrine    is    to   ensure      that
    individual     panels      of   our    court      do   not   --    in   an    ad     hoc
    way -- second-guess prior circuit precedents just because the
    panels are convinced that those precedents are wrong.                        Thus, the
    determination of whether a prior panel decision binds a future
    panel cannot depend on whether there are sound reasons to conclude
    that the prior panel got it wrong.                Yet, the post-Eatherton body
    - 30 -
    of precedent that the dissent invokes shows, in our view, that
    there are merely reasons of that sort when it comes to Eatherton,
    as that body of caselaw fails to provide "a clear and convincing
    basis to believe that the [Eatherton] panel would have decided the
    issue differently."       Guerrero, 19 F.4th at 552.
    A comparison of this case with Guerrero -- which is our
    most     recent    case   to   find   the   second   exception   to   the
    law-of-the-circuit doctrine to be satisfied -- underscores the
    point.    In finding the second exception to the doctrine applicable
    there, we relied on an unbroken string of intervening Supreme Court
    precedents.       Id. at 555-57.   Those precedents, we explained, each
    had made sweeping statements that contradicted the very rationale
    that the prior panel had relied on in ruling that a warrantless
    search had to be subjectively and not just objectively aimed at
    addressing an exigency to be lawful.         See id., 19 F.4th at 554.
    And while we acknowledged that none of those precedents directly
    overruled the prior panel decision, we pointed out that one of
    them rejected the application of a subjective test with respect to
    a home search, notwithstanding that the prior panel had applied
    that test to a search of an automobile.       See id. at 555-56 (citing
    Maryland v. Buie, 
    494 U.S. 325
     (1990)).         We thus explained that,
    given the heightened privacy interests at stake in home searches,
    it would be most strange to conclude that the prior panel would
    stick with its position that a subjective test had to be used for
    - 31 -
    a search of a car if that panel had the benefit of the intervening
    Supreme Court precedent.     See id. at 557.
    Here, by contrast, the relevant intervening Supreme
    Court precedents are Chadwick and Gant -- neither of which even
    addresses a search of personal property carried by an arrestee at
    the time of the arrest, let alone whether and how to distinguish
    between types of such personal property, at least as between
    briefcases and cigarette packages.     We thus do not see how we could
    reason from either of those precedents to the determination that
    there is a clear and convincing basis on which to conclude that
    the Eatherton panel would have decided differently with the benefit
    of knowing what we now do.    And the fact that sister circuits have
    relied on Chadwick and Gant to chart a different course than
    Eatherton cannot provide the required clarity, as the second
    exception to the law-of-the-circuit doctrine does not apply just
    because several other circuits have chosen not to follow one of
    our prior rulings.
    Accordingly,       we     conclude    that,    under    the
    law-of-the-circuit doctrine, the en banc process supplies the
    proper means for our Court to reconsider Eatherton in light of all
    that has transpired in its wake.      Through that process, the Court
    as a whole rather than this single panel can examine Eatherton and
    the question of whether Eatherton's line-drawing concern justifies
    its decision to treat an openly carried container like a briefcase
    - 32 -
    the way that the Supreme Court treated the cigarette containers in
    Robinson and Gustafson and the clothing in Edwards.   And so, until
    then, the rule laid down in Eatherton controls this case about the
    things we carry, as Perez makes no argument that Eatherton can be
    distinguished on the facts.6
    III.
    For the reasons set out above, the District Court's
    judgment of conviction is affirmed.
    -Dissenting Opinion Follows-
    6 We do recognize that a determination that a Fourth Amendment
    precedent of our court remains binding may well bear on whether
    the good-faith exception to the warrant requirement applies. See
    Davis, 
    564 U.S. at 232
     ("[P]olice . . . searches conducted in
    objectively reasonable reliance on binding appellate precedent are
    not subject to the exclusionary rule.").      But, given the vital
    role that the law-of-the-circuit doctrine plays in ensuring the
    orderly process of lower court adjudication, that fact provides no
    reason for us to be less strict in applying the law-of-the-circuit
    doctrine than we have long been.
    - 33 -
    MONTECALVO, Circuit Judge, dissenting.            I view United
    States v. Eatherton, 
    519 F.2d 603
     (1st Cir. 1975), differently
    than the majority, particularly as to how the exception to the
    law-of-the-circuit      doctrine   applies      here.       Further,    applying
    modern Supreme Court precedent, I would find that the search of
    Perez's backpack violated his Fourth-Amendment rights.                   I would
    also find that the good-faith exception is not applicable here.
    Accordingly, and for the reasons that follow, I would reverse the
    decision of the district court on Perez's motion to suppress and
    vacate the judgment of conviction.
    I. The Law-of-the-Circuit Doctrine
    This appeal arises from the denial of a motion to
    suppress the warrantless search of the backpack Perez was wearing
    at the time of his arrest.         As the majority notes, that search
    should   be    viewed   through   the   scope   of   "the    basic     rule   that
    'searches conducted outside the judicial process, without prior
    approval by judge or magistrate are per se unreasonable under the
    Fourth Amendment -- subject only to a few specifically established
    and well-delineated exceptions.'"         Arizona v. Gant, 
    556 U.S. 332
    ,
    338 (2009) (quoting Katz v. United States, 
    389 U.S. 347
    , 357
    (2009)).      One such exception is that of the search incident to
    arrest. 
    Id.
     There are two grounding principles to that exception:
    (1) to protect officer safety and (2) to preserve evidence.                   
    Id.
    - 34 -
    The     development     of       this   exception    has    evolved   over
    decades of caselaw, both in the Supreme Court and this Circuit.
    To that end, as to our prior decisions, we are bound by the
    law-of-the-circuit doctrine.              United States v. Barbosa, 
    896 F.3d 60
    , 74 (1st Cir. 2018).              However, there are exceptions to that
    doctrine, as it is "neither a straightjacket nor an immutable
    rule."      
    Id.
     (quoting Carpenters Local Union No. 26 v. U.S. Fid. &
    Guar. Co., 
    215 F.3d 136
    , 142 (1st Cir. 2000)).                      One exception is
    "when the holding of a previous panel is contradicted by subsequent
    controlling authority, such as a decision by the Supreme Court, an
    en   banc    decision     of   the    originating        court,     or   a    statutory
    overruling."       
    Id.
        Another exception exists "when 'authority that
    postdates      the       original     decision,          although       not    directly
    controlling, nevertheless offers a sound reason for believing that
    the former panel, in light of fresh developments, would change its
    collective mind.'"         
    Id.
     (quoting Williams v. Ashland Eng'g Co., 
    45 F.3d 588
    , 592 (1st Cir. 1995)).
    The majority's opinion rests on a case decided by a panel
    of   this    court    nearly   half       a    century    ago:    United      States   v.
    Eatherton, 
    519 F.2d 603
     (1st Cir. 1975).                         Admittedly, should
    Eatherton remain good law, it is controlling here.                         In my view,
    however, the second exception to the law-of-the-circuit doctrine,
    delineated above, is applicable under these circumstances.                             In
    light of the major developments to the search-incident-to-arrest
    - 35 -
    exception    postdating   Eatherton,      including       modern     binding      and
    persuasive precedent on the propriety of warrantless searches
    incident to arrest, I think that the Eatherton panel would have
    come to a different conclusion.           To justify this conclusion, an
    analysis    of   Eatherton     itself    and     a   brief    history      of     the
    developments following Eatherton's publication is necessary.
    A. Eatherton
    As described in the majority opinion, Eatherton involved
    the warrantless search of a briefcase that the arrestee was holding
    when first approached by law enforcement.               
    519 F.2d at 609
    .        After
    the arrestee was frisked and placed in the back of a police
    vehicle, the officers searched the briefcase, and the contents
    were later admitted at trial.           
    Id.
        The defendant challenged the
    search of his briefcase as violative of his Fourth-Amendment
    rights.    
    Id. at 609-10
    .
    The Eatherton panel noted that the appellant's strongest
    support for his Fourth-Amendment challenge laid in Chimel v.
    California, 
    395 U.S. 752
     (1962); however, the panel recognized
    that Chimel cited with approval to Draper v. United States, 
    358 U.S. 307
     (1959), a case involving a "virtually identical" search
    to the one at issue in Eatherton.         
    519 F.2d at 610
    .         The Eatherton
    panel then cited to a number of cases from our sister circuits
    that,     applying   Chimel,    upheld        similar     searches    of    closed
    containers carried by the arrestee. 
    519 F.2d at
    610 (citing United
    - 36 -
    States v. Maynard, 
    439 F.2d 1086
     (9th Cir. 1971); United States v.
    Mehciz, 
    437 F.2d 145
     (9th Cir. 1971), cert. denied, 
    402 U.S. 974
    (1971); United States ex rel. Muhammad v. Mancusi, 
    432 F.2d 1046
    (2d Cir. 1970), cert. denied, 
    402 U.S. 911
     (1971)).                Lastly, the
    Eatherton    panel    noted   that    the     Supreme   Court's    then-recent
    decisions in United States v. Robinson, 
    414 U.S. 218
     (1973);
    Gustafson v. Florida, 
    414 U.S. 260
     (1973); and United States v.
    Edwards, 
    415 U.S. 800
     (1974), offered further guidance on the
    Fourth-Amendment issue.       
    519 F.2d at 610
    .
    Relying on this case law, the Eatherton panel determined
    that differentiating between the cigarette packages in Robinson
    and Gustafson and the briefcase in Eatherton "requir[ed] gossamer
    distinctions."       
    Id. at 610
    .     The panel further held that "[w]hile
    a briefcase may be a different order of container from a cigarette
    box, it is not easy to rest a principled articulation of the reach
    of the [F]ourth [A]mendment upon the distinction."                
    Id.
       Relying
    on Edwards, the Eatherton panel emphasized that once the briefcase
    was "properly seized" as "incident to [the defendant's] arrest"
    any expectation of privacy the defendant held was diminished.              
    Id. at 610-11
    .
    B. Chadwick
    After Eatherton, the Supreme Court decided United States
    v. Chadwick, 
    433 U.S. 1
     (1977).          In Chadwick, the Court examined
    the search of a 200-pound footlocker stowed in the trunk of the
    - 37 -
    defendant's car at the time of arrest.           
    433 U.S. at 3-4
    .       Officers
    subsequently seized the footlocker, transported it to a federal
    building, and then, an hour and a half later and without a warrant,
    searched the footlocker.       
    Id. at 4
    .      The officers had no reason to
    believe     the   footlocker    held    inherently       dangerous     items   or
    contained evidence that could lose value over time. 
    Id.
     Examining
    the nature of the footlocker, the Court noted that "[l]uggage
    contents are not open to public view . . . nor is luggage subject
    to regular inspections and official scrutiny on a continuing
    basis."    
    Id. at 13
    .   "[L]uggage is [also] intended as a repository
    of personal effects."     
    Id.
    Chadwick    reiterated     that     "[t]he     potential     dangers
    lurking in all custodial arrests make warrantless searches of items
    within the 'immediate control' area reasonable without requiring
    the arresting officer to calculate the probability that weapons or
    destructible evidence may be involved."            
    433 U.S. at 14-15
    .          But
    Chadwick    importantly   clarified     that    "warrantless     searches       of
    luggage or other property seized at the time of an arrest cannot
    be justified as incident to that arrest either if the search is
    remote in time or place from the arrest . . . or no exigency
    exists."     
    Id. at 15
     (cleaned up).          Finally, the Chadwick Court
    concluded    that   "[o]nce    law   enforcement     officers   have     reduced
    luggage or other personal property not immediately associated with
    the person of the arrestee to their exclusive control, and there
    - 38 -
    is no longer any danger that the arrestee might gain access to the
    property to seize a weapon or destroy evidence, a search of that
    property is no longer an incident of the arrest."        
    Id.
       Put another
    way, "when no exigency is shown to support the need for an
    immediate search, the Warrant Clause places the line at the point
    where the property to be searched comes under the exclusive
    dominion of police authority."      
    Id.
    C. Cases Postdating Chadwick
    After Chadwick, several of our sister circuits addressed
    situations involving items that an arrestee was holding or carrying
    at the time of arrest and questioned the breadth of Chadwick,
    reaching mixed results.       See United States v. Han, 
    74 F.3d 537
    ,
    543   (4th    Cir.   1996)   (finding   that,   after   Chadwick,   "[t]he
    determinative question appears to be whether the time and distance
    between elimination of the danger and performance of the search
    were reasonable" and holding that "when a container is within the
    immediate control of a suspect at the beginning of an encounter
    with law enforcement officers; and when the officers search the
    container at the scene of the arrest; the Fourth Amendment does
    not prohibit a reasonable delay . . . between the elimination of
    danger and the search"); see also United States v. Garcia, 
    605 F.2d 349
    , 356-57 (7th Cir. 1979) (noting the "less than uniform"
    application of Chadwick across the circuits).
    - 39 -
    In United States v. Calandrella, 
    605 F.2d 236
     (6th Cir.
    1979), cert. denied, 
    444 U.S. 991
     (1979), the            Sixth Circuit
    examined a briefcase seized from the person at the time of arrest.
    That court, examining Chadwick, noted that "the primary [F]ourth
    [A]mendment interest [is] in the privacy of the contents of [a
    container], not in the simple possession of the receptacle."          Id.
    at 249. Therefore, the defendant had an increased privacy interest
    in the briefcase, like the footlocker in Chadwick, the "very
    purpose [for which] is to transport papers and other items of an
    inherently personal, private nature."       Id. (internal quotations
    omitted).     Ultimately, the Calandrella court found that under
    Chadwick, "once the agents had seized the item and reduced it to
    their exclusive control there was no further danger that the
    defendant     would   secure   therefrom   either   a   weapon   or   an
    instrumentality of escape, or would destroy evidence contained in
    the briefcase."       Id. at 249, 251-52 (expressly overturning its
    prior line of cases upholding searches of suitcases "even after
    the item has been seized and the suspect subdued" and citing to
    courts that had made similar decisions prior to Chadwick, including
    Eatherton).
    Several other circuits also recognized the applicability
    of Chadwick to cases involving carried containers.          See United
    States v. Berry, 
    571 F.2d 2
    , 3 (7th Cir. 1978) (holding that "until
    Chadwick, there was no reason for law enforcement officials to
    - 40 -
    believe that attache cases were not among those personal effects
    which, under [Robinson], could be seized as part of a 'full search
    of the person' incident to a lawful arrest, and which, under
    [Edwards], could be searched several hours after the suspect had
    been taken into custody"); see also United States v. Stewart, 
    595 F.2d 500
    , 503 (9th Cir. 1979) (finding that if Chadwick was
    applicable, "it would require suppression of the contents of the
    attache case"); United States v. Myers, 
    308 F.3d 251
    , 273 (3d Cir.
    2002) (examining the search of a "school bag" under the immediate
    control analysis and citing Chadwick's rationale).
    D. Gant
    Later, in Arizona v. Gant, 
    556 U.S. 332
     (2009), the Court
    revisited the search-incident-to-arrest exception.     The Court once
    again emphasized that the limitation on that exception "ensures
    that the scope of a search incident to arrest is commensurate with
    its purposes of protecting arresting officers and safeguarding any
    evidence of the offense of arrest that an arrestee might conceal
    or destroy."    
    Id. at 339
    .    Relying on the principles articulated
    in Chimel, the Court reiterated that "[i]f there is no possibility
    that an arrestee could reach into [an] area that law enforcement
    officers   seek      to   search,   both   justifications   for   the
    search-incident-to-arrest exception are absent and the rule does
    not apply."

    E. Cases Postdating Gant
    The   decision     in   Gant   has   been    instrumental     in   the
    understanding and application of the Fourth Amendment and the
    search-incident-to-arrest doctrine.                After Gant, circuit courts
    applied that precedent and the immediate control analysis to
    containers outside of the vehicle context.                 See United States v.
    Shakir, 
    616 F.3d 315
    , 318 (3d Cir. 2010), cert. denied, 
    562 U.S. 1116
     (2010) (examining the search of a gym bag under the "narrowed"
    scope    of   the   search-incident-to-arrest            doctrine   under      Gant);
    United   States     v.   Cook,    
    808 F.3d 1195
    ,    1199   (9th   Cir.   2015)
    (applying the immediate control analysis to a backpack); United
    States v. Davis, 
    997 F.3d 191
    , 193 (4th Cir. 2021) (holding that
    "Gant applies beyond the automobile context to the search of a
    backpack"); United States v. Knapp, 
    917 F.3d 1161
    , 1168-70 (10th
    Cir. 2019) (considering whether the search of an arrestee's purse
    was justified under Chimel and Gant); see also United States v.
    Hill, 
    818 F.3d 289
    , 295 (7th Cir. 2016) (applying immediate control
    analysis to bag); United States v. Matthews, 
    532 Fed. Appx. 211
    ,
    217-19 (3d Cir. 2013) (finding that the search of a backpack could
    not be justified under the immediate control analysis of the
    search-incident-to-arrest doctrine); cf. United States v. Perdoma,
    
    621 F.3d 745
    , 750-51 (8th Cir. 2010), cert. denied, 
    563 U.S. 992
    (2011) (upholding the warrantless search of a "small bag" where
    "the search of the bag occurred in close proximity to where [the
    - 42 -
    arrestee] was restrained" and the arrestee had already run from
    officers once; but holding that a closer application of Gant was
    not necessary under the circumstances).        Many of these cases are
    instructive as to how Gant must be applied to cases involving
    carried containers.
    In   Shakir,   the   Third    Circuit    was   faced    with     the
    warrantless search of a gym bag initially held by an arrestee.
    
    616 F.3d at 316
    .    The defendant there argued that the search of
    his bag was in violation of his Fourth-Amendment rights because he
    was already handcuffed at the time of the search and could not
    have accessed the bag.    
    Id. at 317
    .      In response, the government
    cited several cases upholding searches conducted while an arrestee
    was handcuffed.    
    Id.
       However, the Third Circuit noted that the
    government relied solely on pre-Gant cases.        
    Id. at 318
    .    The court
    emphasized "Gant as refocusing [its] attention on a suspect's
    ability (or inability) to access weapons or destroy evidence at
    the time a search incident to arrest is conducted."              
    Id.
         Thus,
    the Shakir court was "left to consider, under Gant and other
    relevant precedents, whether [the defendant] retained sufficient
    potential access to his bag to justify a warrantless search."              
    Id. at 319
    .
    In   considering     that    question,   our   sister        circuit
    "underst[ood] Gant to stand for the proposition that police cannot
    search a location or item when there is no reasonable possibility
    - 43 -
    that the suspect might access it."           
    Id. at 320
    .      In accordance
    with that principle, it held that "a search is permissible incident
    to a suspect's arrest when, under all the circumstances, there
    remains a reasonable possibility that the arrestee could access a
    weapon or destructible evidence in the container or area being
    searched."   
    Id. at 321
    .    Applying this legal standard to the facts
    there, the Third Circuit concluded that the search was justified
    because there was a "sufficient possibility" that the arrestee
    could have gained access to the bag.          
    Id.
         The court found this
    even though the arrestee was handcuffed because the bag was at his
    feet, he was in a public area surrounded by approximately twenty
    bystanders, and there was at least one suspected confederate in
    the area.    
    Id. at 316, 321
    .
    The   Ninth   Circuit    confronted     similar   questions   in
    assessing the validity of a warrantless backpack search in Cook.
    
    808 F.3d at 1199-1200
    .     There, the arrestee was wearing a backpack
    at the time the officers approached him.          
    Id. at 1197
    .    While the
    arrestee was handcuffed on the ground, but within one to two
    minutes of his arrest, officers picked up the arrestee's backpack,
    which was right next to the arrestee, and conducted a twenty- or
    thirty-second cursory search.         
    Id.
        The officers then took the
    arrestee to a more secluded area several blocks away and performed
    a more thorough search of the backpack.             
    Id.
       The arrestee only
    challenged the validity of the first cursory search of his backpack
    - 44 -
    immediately following his arrest.       
    Id. at 1198
    .       Relying on Gant,
    our sister circuit found that "[t]he brief and limited nature of
    the [initial] search, its immediacy to the time of arrest, and the
    location of the backpack ensured that the search was 'commensurate
    with   its     purposes    of   protecting     arresting        officers   and
    safeguarding any evidence of the offense of arrest that [the
    arrestee] might conceal or destroy.'"         
    Id. at 1200
     (quoting Gant,
    
    556 U.S. at 339
    ).
    In Davis, the Fourth Circuit examined the history of the
    search-incident-to-arrest       exception    and   how   Gant    altered   its
    understanding of that exception.       997 F.3d at 195-200.         The Davis
    court found that Gant's first holding, "that police can 'search a
    vehicle incident to a recent occupant's arrest only when the
    arrestee is unsecured and within reaching distance of the passenger
    compartment at the time of the search'" -- a holding derived from
    Chimel -- applies outside of the automobile context.               Id. at 197
    (quoting Gant, 
    556 U.S. at 343
    ).
    After establishing Gant's applicability outside of the
    automobile search context, the Fourth Circuit analyzed whether the
    warrantless search of a backpack was permissible under Gant.               Id.
    at 198.   In Davis, the arrestee fled from officers while carrying
    his backpack but ultimately became bogged down in a swamp with
    knee-high water.     Id.   An officer drew his weapon and ordered the
    arrestee out of the swamp.      Id.   The arrestee complied and dropped
    - 45 -
    his backpack on the ground; he then laid down and was handcuffed.
    Id.    Two other officers arrived at the scene, and the officers
    searched the backpack that was not within the arrestee's reaching
    distance.     Id.
    The Fourth Circuit then held that the warrantless search
    of the backpack was unlawful, reasoning that there was "no doubt
    that [the arrestee] was secured and not within reaching distance
    of his backpack when [the officer] unzipped and searched it."                   Id.
    At    the   time    of   the    search,    the   arrestee   was   face   down   and
    handcuffed, he was outnumbered by officers three to one, and the
    events had occurred in a residential area with no other people
    present; the court thus had "no difficulty" in determining that
    the arrestee was secured.            Id.   The court also emphasized that the
    arrestee was not within reaching distance of the backpack at the
    time of the search.            Id.
    F. The Impact of Modern Authority on Eatherton
    In examining the above cases carefully, I agree with the
    majority that we do not have a Supreme Court opinion that is
    "directly on point contradicting our precedent" in Eatherton.
    United States v. Wurie, 
    867 F.3d 28
    , 34 (1st Cir. 2017).                 However,
    I remain convinced that the "less common exception" to the law-
    of-the-circuit       doctrine        forecloses    our   present    reliance     on
    Eatherton.         The    authorities      discussed     above,    "although    not
    directly controlling, offer[] a sound reason for believing that
    - 46 -
    the [Eatherton] panel would change its collective mind."    
    Id.
       "A
    Supreme Court opinion need not be directly on point to undermine
    one of our opinions."    United States v. Holloway, 
    630 F.3d 252
    ,
    258 (1st Cir. 2011).    Further, a decision of the Supreme Court
    "can extend through its logic beyond the specific facts of its
    case."   
    Id.
     (quoting Los Angeles Cnty. v. Humphries, 
    562 U.S. 29
    ,
    38 (2010)).
    Unlike the district court, who must apply our "precedent
    unless it has unmistakably been cast into disrepute by supervening
    authority," the exceptions to the law-of-the-circuit doctrine
    provide us with "modest" flexibility in the application of our own
    precedents.   Eulitt ex rel. Eulitt v. Me. Dep't of Educ., 
    386 F.3d 344
    , 349 (1st Cir. 2004), abrogated on other grounds by Carson as
    next friend of O.C. v. Makin, 
    596 U.S. 767
     (2022).     The majority
    decision stresses that the second exception to the law-of-the-
    circuit doctrine "cannot depend on whether there are sound reasons
    to conclude that the prior panel got it wrong."   However, the scope
    of the exception applied here is not based on whether I believe
    there are sound reasons to conclude that the Eatherton panel was
    wrong, but rather whether there are sound reasons for believing
    that the Eatherton panel would have changed its collective mind.
    And this "sound reason" standard has been reiterated by this court.
    See e.g., Lewis, 963 F.3d at 23; United States v. López, 
    890 F.3d 332
    , 340 (1st Cir. 2018); Wurie, 
    867 F.3d at 34
    .
    - 47 -
    Given that scope, in my view, had the Eatherton panel
    had the benefit of both Chadwick and Gant, that panel would have
    changed its collective mind as to its interpretation of the
    search-incident-to-arrest doctrine.         As our sister circuits have
    concluded,   Chadwick   and,    perhaps     even    more   so,    Gant    have
    unquestionably     altered        our       understanding         of      the
    search-incident-to-arrest      doctrine    and     "provide   a   clear   and
    convincing basis" to determine that the Eatherton panel too would
    have come to a different conclusion on the issue.             See Guerrero,
    19 F.4th at 552.
    Chadwick made a nuanced distinction between the reduced
    expectation of privacy an arrestee has of their person as compared
    to possessions within their immediate control at the time of
    arrest.   
    433 U.S. at
    16 n.10.      Further, Chadwick's analysis did
    not hinge on whether the possession was held by the arrestee or
    was elsewhere in their vicinity.        Instead, Chadwick focused on the
    nature of containers as "repositor[ies] of personal effects."7 
    Id.
    7 Indeed, the Supreme Court seems to agree that the result in
    Chadwick would not have been different had the arrestee been
    "drag[ging] [the trunk] behind them." Riley v. California, 
    573 U.S. 373
    , 394 (2014) (acknowledging the difference between the
    trunk in Chadwick -- which could hold a large number of personal
    items and required a warrant to search -- and "a container the
    size of [a] cigarette package" at issue in Robinson). In my view,
    Riley lends support for the very line-drawing about different
    carried containers that Eatherton believed it was unable to make.
    The majority appears to suggest that Riley distinguishes between
    personal property that is difficult to carry, either due to its
    size or weight, and personal property that is commonly carried,
    - 48 -
    at 13.     Thus, although the Eatherton panel was understandably
    influenced by the then-recent cases of Edwards, Robinson, and
    Gustafson when assessing an arrestee's privacy interests, Chadwick
    would    have   provided   the   additional   context   that   "possessions
    within an arrestee's immediate control cannot be justified by any
    reduced expectations of privacy caused by the arrest."            
    433 U.S. at
    16 n.10 (emphasis added).
    Given this understanding and Gant's refined framework
    for "immediate control" searches, the Eatherton panel would have
    centered    its   analysis   around   "immediate   control"    rather   than
    shoehorning the search of a closed container into being "of the
    person."    Specifically, I believe this modern authority would have
    led the Eatherton panel to the conclusion, under Chadwick and Gant,
    that searches of visible containers held or carried by an arrestee
    -- like the briefcase in Eatherton -- must be treated as "immediate
    such as a briefcase. See Majority at 30. I do not think this was
    the Riley Court's intent. Riley notes that "[m]ost people cannot
    lug around every piece of mail they have received for the past
    several months, every picture they have taken, or every book or
    article they have read -- nor would they have any reason to attempt
    to do so." Id. at 393-94. But, the Riley Court then states that
    the only way for a person to carry personal property like that
    (prior to the existence of cell phones) would be to "drag behind
    them a trunk of the sort held to require a search warrant in
    Chadwick."    Id. at 394.     In my view, the Riley Court was
    differentiating between certain containers that may be receptacles
    for other personal property and small containers like those the
    size of a cigarette package, while emphasizing that a container
    like the trunk in Chadwick would have required a search warrant
    just as a cell phone would. Id. at 394.
    - 49 -
    control" searches.          See Knapp, 
    917 F.3d at 1167
     (limiting Robinson
    searches      to   "searches        of   an    arrestee's       clothing,       including
    containers concealed under or within her clothing" and holding
    that "visible containers in an arrestee's hand . . . are best
    considered to be within the area of an arrestee's immediate
    control").
    Further,      the    parties      here     have      not   identified    any
    post-Gant      published      circuit         opinions      that    adopted     the   same
    approach taken in Eatherton.              Indeed, we have found the opposite:
    circuits    that     once    took    an    Eatherton-like           approach     to   cases
    involving carried containers now applying the "immediate control"
    analysis in similar circumstances.                  Cf. United States v. Lewis,
    
    963 F.3d 16
    , 24 (1st Cir. 2020) (adhering to the law-of-the-circuit
    doctrine where three sister circuits retained allegiance to this
    Circuit's reasoning despite a recent Supreme Court decision);
    Sanchez v. United States, 
    740 F.3d 47
    , 57 (1st Cir. 2014) (finding
    that just two circuits' decisions contrary to our precedent "hardly
    paint a picture of a rush to the exit so as to allow us to overrule
    our   own     controlling         precedent").         In    short,      the    continued
    application of Eatherton simply "runs counter to the strong modern
    trend in the caselaw."             United States v. Guerrero, 
    19 F.4th 547
    ,
    557 (1st Cir. 2021).
    Accordingly, I find "that the gloss added by the Supreme
    Court"   to    the   search-incident-to-arrest                exception        requires   a
    - 50 -
    different approach than that taken by the Eatherton panel.            United
    States v. Rodriguez, 
    527 F.3d 221
    , 225 (1st Cir. 2008).              Had the
    Eatherton panel had the benefit of viewing that case "through the
    prism of" Chadwick and Gant, I believe that they would have come
    to a different result.       
    Id. at 226
    ; see Guerrero, 19 F.4th at 559
    ("The bottom line [] is that given the Supreme Court cases in vogue
    after [our prior decision], we believe [that] panel would (if it
    had the chance) reverse its view of the . . . issue 180 degrees.").
    For these reasons, I would find that Eatherton is no
    longer the law of the circuit. Instead, the appropriate rule under
    Chadwick   and   Gant   is   that   the   searches   of   visible,    closed
    containers held or carried by an arrestee should be analyzed as
    "immediate control" searches.
    II. Fourth-Amendment Violation
    Because I would hold that Eatherton is no longer the law
    of the circuit and that the search of the backpack here should be
    treated as an immediate control search, the next step is to
    determine whether the search was nonetheless justified under the
    circumstances presented.      Appropriate factors to be considered in
    that inquiry are: "(1) whether the arrestee is handcuffed; (2) the
    relative number of arrestees and officers present; (3) the relative
    positions of the arrestees, officers, and the place to be searched;
    . . . (4) the ease or difficulty with which the arrestee could
    gain access to the searched area"; and (5) "the degree to which
    - 51 -
    arresting officers have separated an article from an arrestee at
    the time of the search."     Knapp, 
    917 F.3d at 1168-69
    .
    The district court made the necessary factual findings
    to support a conclusion that the search of Perez's backpack was
    violative of his Fourth-Amendment rights. The district court found
    that "Perez was secured in handcuffs on the ground under [one
    officer's] supervision as [another officer] was searching the
    backpack on the hood or roof of [one of the officer's] vehicle,
    not within reaching distance of Perez, so destruction of evidence
    or access to weapons was not at stake."8       Accordingly, I would find
    that under the immediate control analysis, the search of Perez's
    backpack was in contravention with the warrant requirement of the
    Fourth    Amendment    and      did      not      fall    within    the
    search-incident-to-arrest exception.
    III. Good Faith
    Finding that the search of Perez's backpack violated the
    Fourth Amendment, however, is not the end of the inquiry.           The
    8 The government has argued before us that the backpack was
    near Perez at the time of the search and that "there was a
    reasonable possibility that he could access the bag," and the
    search was therefore justified under the immediate control
    analysis. However, it has not pointed us to any support to find
    that the district court's determinations regarding Perez's
    inability to reach the backpack at the time of the search were
    clearly erroneous. See United States v. Oquendo-Rivas, 
    750 F.3d 12
    , 16 (1st Cir. 2014) ("We assess questions of fact . . . for
    clear error."). I also do not surmise any support in the record
    to find a clear error in the district court's factual findings.
    - 52 -
    Fourth Amendment "says nothing about suppressing evidence obtained
    in violation of [its] command."    Davis v. United States, 
    564 U.S. 229
    , 236 (2011).    I must thus determine if the exclusionary rule
    is applicable here.    "The rule's sole purpose . . . is to deter
    future Fourth[-]Amendment violations" and not to redress prior
    violations.   
    Id. at 236-37
    .      "Our cases have thus limited the
    rule's operation to situations in which this purpose is 'thought
    most efficaciously served.'"   
    Id. at 237
     (quoting United States v.
    Calandra, 
    414 U.S. 338
    , 348 (1974)).
    "When the police exhibit 'deliberate,' 'reckless,' or
    'grossly negligent' disregard for Fourth[-]Amendment rights, the
    deterrent value of exclusion is strong and tends to outweigh the
    resulting costs."   Id. at 238 (quoting Herring v. United States,
    
    555 U.S. 135
    , 144 (2009)).     On the other hand, "when the police
    act with an objectively reasonable good-faith belief that their
    conduct is lawful . . . or when their conduct involves only simple,
    isolated negligence[,] . . . the deterrence rationale loses much
    of its force, and exclusion cannot pay its way."      
    Id.
     (internal
    quotations omitted).   "The government bears the burden of showing
    that its officers acted with objective good faith."   United States
    v. Sheehan, 
    70 F.4th 36
    , 51 (1st Cir. 2023) (quoting United States
    v. Brunette, 
    256 F.3d 14
    , 17 (1st Cir. 2001)).
    The good-faith exception may be triggered "when the
    police conduct a search in objectively reasonable reliance on
    - 53 -
    binding    judicial   precedent."      Davis,    
    564 U.S. at 239
    .   But
    importantly, this "exception is available only where the police
    rely on precedent that is clear and well-settled."             United States
    v. Sparks, 
    711 F.3d 58
    , 64 (1st Cir. 2013) (cleaned up).             "[W]here
    judicial    precedent   does   not    clearly    authorize     a   particular
    practice, suppression has deterrent value because it creates an
    'incentive to err on the side of constitutional behavior.'" United
    States v. Bain, 
    874 F.3d 1
    , 20 (1st Cir. 2017) (quoting Sparks,
    
    711 F.3d at 64
    ).
    Had this case fallen within the first exception to the
    law-of-the-circuit doctrine -- where "the holding of a previous
    panel is contradicted by subsequent controlling authority" -- the
    good-faith exception would plainly not apply.             See Barbosa, 
    896 F.3d at 74
    .     For example, imagine a scenario where, post-Gant,
    officers searched a vehicle incident to a recent occupant's arrest
    after the occupant was secured and not within reaching distance of
    the passenger compartment and without probable cause that the
    vehicle contained evidence of the offense of arrest.               Regardless
    of whether prior circuit law allowed this practice, that search
    would be unlawful post-Gant, and the officers could not rely on
    good faith.
    Admittedly,    when      the     second    exception     to   the
    law-of-the-circuit doctrine applies, as I believe it does here,
    there is a much closer question as to whether the good-faith
    - 54 -
    exception applies.        Ultimately, given the deterrent value of
    enforcing a regime where officers err on the side of constitutional
    conduct in the face of unclear or eroded precedent, I would not
    permit good faith to bar exclusion in this case.
    First and foremost, for the same reasons that I find the
    second exception to the law-of-the-circuit doctrine applies here,
    I am of the view that Eatherton was not the kind of "clear and
    well-settled" precedent that officers could reasonably rely on.
    See Sparks, 
    711 F.3d at 64
    . At the very minimum, Gant -- a landmark
    case in our Fourth-Amendment jurisprudence -- called into question
    the continued vitality of Eatherton.              It would be untenable to
    require that Supreme Court holdings address virtually identical
    factual   scenarios     before    we    consider       our    circuit     precedent
    undermined and reject application of the good-faith exception.
    Such a requirement would be contrary to the requirement that the
    precedent   officers    rely     upon   "be    unequivocal"      when     shielding
    unlawfully obtained evidence from exclusion.                 Sparks, 
    711 F.3d at 64
    .
    Second,    this   conclusion       aptly   aligns     with    the   very
    purpose of the exclusionary rule: to deter future Fourth-Amendment
    violations.     Davis, 
    564 U.S. at 236-37
    .                   If we do not strip
    precedent     that    falls    within    the     second       exception    to   the
    law-of-the-circuit doctrine of its weight as forcefully as we do
    in cases under the first exception, officers would be encouraged
    - 55 -
    to adhere to shaky precedent (no matter how potentially abrogated)
    until those cases are formally and explicitly overruled.                     Because
    suppression is intended to create the "incentive to err on the
    side     of   constitutional        behavior,"     I     think   the    appropriate
    conclusion is that when opinions authored by the Supreme Court,
    particularly landmark cases like Gant, call into question our prior
    precedent,      officers     must    conform     their    conduct      to   the   more
    protective reading of the Fourth Amendment laid out by the Supreme
    Court.    See Bain, 
    874 F.3d at 20
     (quoting Sparks, 
    711 F.3d at 64
    ).
    Finally, this is not a case where "the police engage[d]
    in conduct that complie[d] with existing precedent, and the law
    later change[d]."       United States v. Baez, 
    744 F.3d 30
    , 33 (1st
    Cir. 2014).      Gant was decided a decade before the search at issue
    here occurred, and Chadwick's guidance on closed containers has
    been binding precedent for over forty years.                Cf. Sparks, 
    711 F.3d at 67
     (finding good faith applied where the applicable Supreme
    Court    case   came   out    three    years     after    the    search     at    issue
    occurred); United States v. Moore-Bush, 
    36 F.4th 320
    , 359 (1st
    Cir. 2022) (mem.) (Barron, C.J., concurring) (concurring opinion
    finding that good faith applied when the applicable Supreme Court
    decision was published over one year after the search began).
    Given my view of the impact of these cases on Eatherton, the
    officers were required to follow the logic supplied by Gant and
    Chadwick.
    - 56 -
    For these reasons, I would conclude that the good-faith
    exception is not available under the circumstances and suppression
    is the proper outcome to deter future Fourth-Amendment violations.
    IV. Conclusion
    For the above stated reasons, I would abrogate Eatherton
    to the extent it is inconsistent with this analysis, reverse the
    district court's decision on the motion to suppress, vacate the
    judgment   of   conviction,    and   remand    for   further   proceedings
    consistent with this opinion.
