    UNITED STATES OF AMERICA,
    Appellee,
    v.
    CHARLES FLORES,
    Defendant, Appellant.
    APPEAL FROM THE UNITED STATES DISTRICT COURT
    FOR THE DISTRICT OF MAINE
    [Hon. Jon D. Levy, U.S. District Judge]
    Before
    Howard, Chief Judge,
    Selya and Barron, Circuit Judges.
    Gail S. Strassfeld for appellant.
    Benjamin M. Block, Assistant United States Attorney, with
    whom Halsey B. Frank, United States Attorney, was on brief, for
    appellee.
    April 25, 2018
    SELYA, Circuit Judge.        This appeal implicates two issues
    rooted in the Fourth Amendment.              See U.S. Const. amend. IV.                The
    first involves the district court's determination that probable
    cause    existed    for    the    arrest    of    defendant-appellant            Charles
    Flores; the second involves the district court's invocation of the
    independent       source    doctrine    and      its   concomitant           refusal    to
    suppress evidence seized during a warrant-backed search of the
    appellant's hotel room, notwithstanding the officers' earlier
    unlawful entry into that room.             Discerning no error, we affirm the
    judgment below.
    I.   BACKGROUND
    When reviewing the denial of a motion to suppress, we
    "take the facts as the trial court found them, consistent with
    record support, adding uncontradicted facts where appropriate."
    United    States     v.    Almonte-Báez,      
    857 F.3d 27
    ,       29    (1st     Cir.
    2017)(internal citation omitted).
    This case has its genesis in a tip received by Thomas
    Pappas,    a    Maine     state   trooper     with     thirteen     years       of     law-
    enforcement      experience,      who   was      seconded     to    a    federal       Drug
    Enforcement Administration (DEA) task force at the times relevant
    hereto.     Specifically, Paul Buchanan, a fellow DEA task force
    member, told Pappas that he had heard from a reliable informant
    that a "group of New Yorkers" was peddling cocaine out of the
    Fairfield Inn (a hotel located in Brunswick, Maine).                           Buchanan
    - 2 -
    explained that, though the informant did not have first-hand
    knowledge of the drug-trafficking enterprise, he had a history of
    providing dependable information and had "participated in a number
    of cases."
    His interest piqued, Pappas drove to the Fairfield Inn
    and was joined there by another officer.        He obtained a guest
    registry from the hotel staff and inquired whether any rooms had
    been paid for in cash (a practice which, Pappas testified, was
    commonly associated with criminal activity because it allowed
    perpetrators to avoid a paper trail).     He learned that, of the 38
    occupied rooms in the hotel, only one — room 131 — had been rented
    for cash.     Next, Pappas explored the hotel grounds, noting that
    room 131 was one of the most easterly rooms; its windows faced the
    parking lot at the rear of the hotel; and it was near a relatively
    private exit.
    The two officers returned to the front of the hotel, and
    Pappas spoke with the front-desk manager.       Unprompted, she told
    the officers that she suspected they were there to investigate
    room 131.     That room, she stated, had been rented by a person who
    listed a New York address.    The room itself was occupied by a group
    of men and women, and one of the guests was an obese black male.
    Upon registration, the group had initially been assigned to a
    second-floor room, asked to be moved, and was transferred to room
    131 (a first-floor room).      According to the manager, there had
    - 3 -
    been an unusual number of visitors "coming and going on a frequent
    basis" to and from room 131.
    With the manager's permission, the officers set up shop
    in a neighboring room:        room 132.   Around 5 p.m., Pappas observed
    a vehicle pull into the parking space directly adjacent to room
    132.        A man was driving and a second man was in the front passenger
    seat.         An obese black male roughly matching the description
    previously provided by the front-desk manager1 approached the car
    and got into the back seat.        Pappas saw this man (later identified
    as the appellant) shift his weight as if reaching for something.
    Pappas then saw the man make an exchange with the front-seat
    passenger (though he could not identify what was exchanged). After
    the exchange, Pappas saw the appellant counting money in the back
    seat and then exit the car.          As Pappas recalled it, the entire
    interaction took no more than 20 to 30 seconds.          Pappas believed
    that he had witnessed a hand-to-hand drug transaction and that the
    appellant had the proceeds (and possibly additional drugs) on his
    person.2
    1While testifying at the suppression hearing, the front-
    desk manager used the word "large," rather than the word "obese,"
    to describe the black man whom she associated with room 131. We
    discern no clear error in the district court's implicit finding
    that, in context, these adjectives were not meaningfully
    dissimilar.
    2  These perceptions were later corroborated in material part
    by the front-seat passenger, who admitted to the authorities that
    he had given the appellant money in exchange for drugs.
    - 4 -
    Shortly after witnessing what he believed to be a drug
    buy, Pappas walked outside and saw the appellant near the exit at
    the eastern end of the hotel.            He noticed that the appellant was
    smoking marijuana.      After taking a lap around the hotel, Pappas
    inquired whether the appellant wanted the outside door held open.
    The appellant indicated that he had his own keycard.
    Pappas   went       inside,    asked     his    fellow   officer    to
    accompany him, and returned to where the appellant was loitering.
    After identifying themselves as law-enforcement officers, they
    detained the appellant and handcuffed him.                Pappas testified that
    handcuffs were necessary to ensure officer safety, to safeguard
    any evidence that the appellant might have on his person, and to
    incapacitate the appellant should any of his confederates be
    nearby.
    The officers proceeded to question the appellant without
    first giving him Miranda warnings.              See Miranda v. Arizona, 
    384 U.S. 436
    , 444 (1966).      They learned that he was from New York and
    was staying in room 131.           A search of the appellant's person
    disclosed that he was carrying two cellphones, a keycard, an
    identification card, and cash.
    The officers then brought the appellant into the hotel.
    As they neared room 131, they thought that they heard voices.
    Using the appellant's keycard, the two officers entered the room.
    Once   inside,   they   were    able     to    determine   that   the   room   was
    - 5 -
    unoccupied and that the voices they had heard were emanating from
    a television set.    They performed a security sweep during which
    they observed, among other things, some cash and a mason jar
    containing marijuana.    Pappas testified that, during this entry,
    the officers simply glanced around and did not search the room
    for, say, drugs, weapons, or the like.
    At this juncture, the officers started to read the
    appellant his Miranda rights.       While those rights were being
    recited, a woman knocked on the door of room 131 and explained
    that she "was sent there by some people from New York" to check on
    the appellant.    Pappas escorted her to room 132 and interviewed
    her there.     He asked for her cellphone, which she surrendered.
    Checking it, Pappas saw drug-related messages and confronted the
    woman about them.    After she tried unsuccessfully to retrieve her
    cellphone, Pappas handcuffed her.
    Pappas called for additional support and proceeded to
    complete the administration of the appellant's Miranda rights.    He
    then asked the appellant for permission to search room 131.
    Failing to receive consent, Pappas waited for reinforcements to
    arrive so that he could then devote his time to preparing a warrant
    application.    Meanwhile, the appellant was kept in room 131.3
    3  We question whether it is sound practice for the police to
    hold a suspect in a room that they believe may contain evidence of
    a crime (especially where, as here, there is a readily available
    - 6 -
    Once reinforcements arrived at the scene, Pappas began
    drafting an application for a search warrant.     The woman who had
    been detained provided a statement that was included in the warrant
    application.   Around 11 p.m., a state-court judge reviewed the
    application and issued a search warrant for room 131.   The ensuing
    search revealed the presence of two bottles containing heroin,
    approximately 200 baggies, and a digital scale.   The officers also
    retrieved from the appellant's person a bottle containing heroin
    and cocaine base (crack cocaine).
    In due course, a federal grand jury sitting in the
    District of Maine returned an indictment charging the appellant
    with possessing controlled substances with intent to distribute.
    See 
    21 U.S.C. § 841
    (a)(1).   The appellant moved to suppress the
    fruits of what he argued was his illegal arrest as well as all
    evidence obtained from his hotel room.   The district court held an
    evidentiary hearing at which Pappas, the front-desk manager, and
    the front-seat passenger who had purchased drugs from the appellant
    in the parking lot appeared as witnesses.   Following the hearing,
    the district court granted the motion to suppress in part and
    denied it in part.    In its rescript, the court found that the
    appellant's detention outside the hotel amounted to a de facto
    arrest, supported by probable cause; that the appellant's pre-
    alternative). This appeal, however, does not require us to probe
    that point more deeply.
    - 7 -
    Miranda statements should be suppressed; and that, even assuming
    that the officers' initial (warrantless) entry into room 131 was
    in derogation of the appellant's Fourth Amendment rights,4 the
    subsequent warrant-backed search was valid under the independent
    source doctrine.   Accordingly, the court declined to suppress the
    evidence seized during that search.    See United States v. Flores,
    No. 2:16-cr-44, 
    2016 WL 7378104
    , at *8 (D. Me. Dec. 20, 2016).
    The appellant entered a conditional guilty plea, see
    Fed. R. Crim. P. 11(a)(2), reserving his right to appeal the
    partial denial of his motion to suppress.       The district court
    accepted the appellant's conditional guilty plea and sentenced him
    to serve a thirty-month term of immurement.     This timely appeal
    followed.
    II.   ANALYSIS
    The appellant challenges the district court's partial
    denial of his motion to suppress on two grounds. First, he asserts
    that the authorities did not have sufficient probable cause to
    4 In the district court, the government claimed that this
    initial entry was justified by exigent circumstances. See, e.g.,
    Almonte-Báez,   857  F.3d   at   33   (explaining  that   exigent
    circumstances can justify warrantless entry into private premises
    if there is probable cause); United States v. Curzi, 
    867 F.2d 36
    ,
    41-42 (1st Cir. 1989)(same). The district court saw no need to
    address this claim and assumed, favorably to the appellant, that
    the initial entry violated the constitutional norm. Before us,
    the government does not renew its "exigent circumstances"
    argument, and we too assume that this initial entry was in
    derogation of the Fourth Amendment.
    - 8 -
    arrest him in the parking lot.                    Second, he asserts that the
    warrant-backed search of room 131 was tainted by the earlier
    (warrantless)       entry   and    was       therefore    unconstitutional.        We
    discuss these assertions sequentially.
    Before undertaking this task, we pause to limn the
    applicable standard of review. In reviewing the denial of a motion
    to suppress, we scrutinize the district court's factual findings
    for clear error and its legal conclusions (including its ultimate
    constitutional determinations) de novo.                   See Ornelas v. United
    States, 
    517 U.S. 690
    , 699 (1996); United States v. Coombs, 
    857 F.3d 439
    , 445-46 (1st Cir. 2017).                 "[W]e will uphold a denial of
    a suppression motion as long as 'any reasonable view of the
    evidence supports the decision.'"                  United States v. Clark, 
    685 F.3d 72
    , 75 (1st Cir. 2012) (quoting United States v. Woodbury,
    
    511 F.3d 93
    , 96-97 (1st Cir. 2007)).
    A. The Arrest.
    The Fourth Amendment guarantees an individual's right
    "to be secure" in his "person[], houses, papers, and effects,
    against unreasonable searches and seizures."                       To satisfy this
    imperative, an arrest — which is the quintessential seizure of a
    person — must be "reasonable under the circumstances."                       District
    of Columbia v. Wesby, 
    138 S. Ct. 577
    , 585 (2018).                     An arrest is
    reasonable if the officer "has probable cause to believe that an
    individual    has    committed     .     .    .   [a]   criminal   offense    in   his
    - 9 -
    presence."      Atwater v. City of Lago Vista, 
    532 U.S. 318
    , 354
    (2001).
    The appellant maintains that his detention outside the
    hotel constituted a de facto arrest, which was effected without
    probable cause and thus transgressed his Fourth Amendment rights.
    A "de facto arrest occurs when 'a reasonable man in the suspect's
    position would have understood his situation, in the circumstances
    then obtaining, to be tantamount to being under arrest.'"                 United
    States v. Jones, 
    700 F.3d 615
    , 624 (1st Cir. 2012) (quoting United
    States v. Zapata, 
    18 F.3d 971
    , 975 (1st Cir. 1994)).               The district
    court found that a de facto arrest took place here, and the
    government      does     not    challenge      this    finding      on   appeal.
    Consequently, the validity of the detention turns on whether the
    officers had probable cause to arrest the appellant at that time.
    As we have explained, "probable cause exists when an
    officer,      acting     upon    apparently      trustworthy       information,
    reasonably can conclude that a crime has been or is about to be
    committed and that the suspect is implicated in its commission."
    Morelli v. Webster, 
    552 F.3d 12
    , 21 (1st Cir. 2009).                "[P]robable
    cause is a fluid concept" and is "not readily, or even usefully,
    reduced to a neat set of legal rules."                Illinois v. Gates, 
    462 U.S. 213
    ,    232   (1983).     It    "requires      only   a   probability   or
    substantial chance of criminal activity, not an actual showing of
    such activity."        
    Id.
     at 243-44 n.13.
    - 10 -
    Probable cause must be assessed on the basis of the
    totality of the circumstances.    See Maryland v. Pringle, 
    540 U.S. 366
    , 372 n.2 (2003).     In considering "whether an officer had
    probable cause for an arrest, 'we examine the events leading up to
    the arrest, and then decide whether these historical facts, viewed
    from the standpoint of an objectively reasonable police officer,
    amount to probable cause.'"      Wesby, 
    138 S. Ct. at 586
     (quoting
    Pringle, 
    540 U.S. at 371
    ).       When suspected criminality gives
    coherence to such historical events, a finding of probable cause
    is often supportable.   See United States v. Favreau, 
    886 F.3d 27
    ,
    30 (1st Cir. 2018).
    With this legal landscape in place, we consider the facts
    known to the officers at the time of the appellant's de facto
    arrest and determine whether that information, viewed objectively,
    gave rise to probable cause.      Pappas came to the Fairfield Inn
    spurred by a tip — which he had reason to believe was reliable —
    that a group of people from New York was peddling drugs from that
    venue.   This tip garnered some preliminary corroboration when
    Pappas, upon arriving at the hotel, learned that the only room
    paid for in cash — which Pappas expected was likely to be the case
    for any room associated with criminal activity — was registered to
    a New York address.   As here, the corroboration of a tip in whole
    or in part through further observation is a factor that may weigh
    - 11 -
    in favor of a finding of probable cause.       See United States v.
    Rasberry, 
    882 F.3d 241
    , 250 (1st Cir. 2018).
    The front-desk manager provided a physical description
    of the guests staying in the room that had been paid for in cash
    (room 131). She noted that those guests received an unusual number
    of visitors and that they had moved to a ground-level room closer
    to an exit.   These facts, too, tended to corroborate the tip.
    Subsequently,   Pappas   witnessed    the   appellant   (an
    individual who roughly matched the physical description provided
    by the front-desk manager) take part in an interaction that
    appeared to be a hand-to-hand drug buy: the interaction transpired
    in a vehicle in the hotel parking lot; the appellant could be seen
    shifting his weight in the back seat to withdraw something from
    his person; an exchange of some sort took place between the
    appellant and the front-seat passenger; and the appellant then
    began counting the money that he apparently had received.         The
    entire episode was completed in 30 seconds or less.          Shortly
    thereafter, Pappas saw the appellant lounging in the parking lot,
    smoking an illegal substance (marijuana).      When Pappas indicated
    that he would hold the hotel door open, the appellant waved him
    off, flashing a keycard and indicating that he was a guest at the
    hotel.
    The whole is sometimes greater than the sum of the parts.
    The historical events leading up to the appellant's arrest were
    - 12 -
    given   coherence    by    the     tip    that   prompted   the    officers    to
    investigate.     See Favreau, 886 F.3d at 30.               That tip had some
    indicia of reliability, and each of the officer's observations
    further corroborated it.          Given the totality of the circumstances
    — especially the fact that Pappas witnessed what he reasonably
    believed to be a hand-to-hand drug buy — we conclude (as did the
    court below) that probable cause existed to arrest the appellant.
    Seeking to dull the force of this analysis, the appellant
    argues that an anonymous tip is not inherently reliable, that the
    use of cash to pay for hotel rooms is not infrequent, that Pappas
    did not actually see drugs exchanged after the appellant entered
    the parked car, and that the appellant's smoking of marijuana was
    consistent with personal use.             The inquiry here, though, is one
    addressed to the existence of probable cause, not one addressed to
    the existence of metaphysical certainty.               Attempting to analyze
    each piece of evidence in a vacuum is inconsistent with Supreme
    Court case law, which makes pellucid that each item is to be
    considered as part of the totality of the circumstances.                      See
    Wesby, 
    138 S. Ct. at 586, 589
     (holding that court erred when it
    "identified     innocent    explanations"        for   probative     facts    "in
    isolation"     because     such     a    "divide-and-conquer       approach    is
    improper"); Pringle, 
    540 U.S. at
    372 n.2 (similar). So it is here:
    while any one of the facts to which the appellant adverts may be
    susceptible to an innocent explanation if regarded in isolation,
    - 13 -
    their cumulative effect is powerful and solidly supports a double-
    edged inference that a crime was being committed and that the
    appellant was committing it.          After all, the Fourth Amendment does
    not   require    that    an     officer    rule    out   potentially    innocent
    explanations     for    every    piece     of    evidence   before    reaching    a
    reasonable conclusion that there is probable cause to believe that
    a crime has been committed and that the suspect has committed it.
    When it waddles like a duck, quacks like a duck, swims like a duck,
    and looks like a duck, it is quite likely to be a duck.
    That ends this aspect of the matter. We discern no error
    in the district court's closely reasoned determination that the
    appellant's de facto arrest in the parking lot comported with the
    strictures of the Fourth Amendment.
    B. The Search.
    This leaves the appellant's claim that the district
    court erred in applying the independent source doctrine to validate
    the warrant-backed search of his hotel room, thus permitting the
    government to use the evidence obtained as a result of that search.
    We commence this portion of our analysis with bedrock:                  a search
    of a dwelling must be reasonable in order to satisfy the Fourth
    Amendment.      See Florida v. Jardines, 
    569 U.S. 1
    , 6 (2013).                  For
    this purpose, a temporary place of abode, such as an individual's
    hotel   room,    is    deemed    to   be   his    dwelling.     See    Stoner    v.
    - 14 -
    California, 
    376 U.S. 483
    , 490 (1964); United States v. Jones, 
    523 F.3d 31
    , 36 (1st Cir. 2008).
    Subject to certain exceptions not relevant here, when "a
    search [of a dwelling] is undertaken by law enforcement officials
    to discover evidence of criminal wrongdoing, reasonableness . . .
    requires      the    obtaining    of    a    judicial    warrant."      Riley     v.
    California, 
    134 S. Ct. 2473
    , 2482 (2014) (internal quotation marks
    omitted).           Such   a   search    conducted      without   a   warrant    is
    "presumptively unreasonable."               Payton v. New York, 
    445 U.S. 573
    ,
    586 (1980).         As a prophylaxis against unreasonable searches, we
    apply    an   exclusionary       rule   that     "prohibits   introduction      into
    evidence of tangible materials seized during an unlawful search
    . . . and of testimony concerning knowledge acquired during an
    unlawful search."          Murray v. United States, 
    487 U.S. 533
    , 536
    (1988) (internal citation omitted).
    In this case, we assume that the officers' initial
    (warrantless) entry into room 131 was in derogation of the Fourth
    Amendment.      See supra note 4.           Even so, not all evidence seized
    after an unlawful entry is subject to exclusion.                  Where, as here,
    a search warrant is subsequently obtained and evidence is seized
    or knowledge obtained as a result of the later warrant-backed
    search, that evidence and/or knowledge may be admissible if the
    warrant derives from sources independent of the earlier (unlawful)
    entry.    See Murray, 
    487 U.S. at 537
    .

    This independent source doctrine recognizes that the
    "interest of society in deterring unlawful police conduct and the
    public interest in having juries receive all probative evidence of
    a crime are properly balanced by putting the police in the same,
    not a worse, position tha[n] they would have been in if no police
    error or misconduct had occurred."      Nix v. Williams, 
    467 U.S. 431
    ,
    443   (1984)   (emphasis   in   original).   Thus,   when   evidence    or
    knowledge would have been gleaned even in the absence of the
    earlier (unlawful) entry, such evidence or knowledge should not be
    excluded.      See 
    id.
       Any other outcome would upset the delicate
    balance that the Nix Court struck by "put[ting] the police in a
    worse position than they would have been in absent any error."

    Against this backdrop, we turn to the case at hand. The
    district court granted the appellant's motion to suppress in part:
    it excluded the statements made by him after his de facto arrest
    and before he received full Miranda warnings.          The government,
    presumably recognizing that statements "elicited in the course of
    [a] custodial interrogation" are "render[ed] inadmissible" if
    Miranda warnings are not given to the party in custody before the
    statements are made, United States v. Candelario-Santana, 
    834 F.3d 8
    , 18 (1st Cir. 2016), does not challenge this ruling.5                The

    statement are admissible against a defendant even if a Miranda
    - 16 -
    district court also excluded any evidence obtained during the
    officers' initial (unlawful) entry into room 131.                 Withal, the
    court denied the motion to suppress with respect to the fruits of
    the warrant-backed entry into room 131.            In its view, the warrant
    was valid under the independent source doctrine notwithstanding
    the earlier (unlawful) entry.         We train the lens of our inquiry on
    this latter ruling, which is hotly contested by the parties.
    The independent source doctrine obliges a reviewing
    court to answer two related questions:                  whether the officers'
    decision to seek a warrant was made independent of what they had
    learned during their earlier (unlawful) entry, and if so, whether
    the affidavit that they submitted to procure the warrant, when
    stripped of any knowledge derived from the initial entry, contained
    enough facts to support a finding of probable cause.              See Murray,
    
    487 U.S. at 542
    ; United States v. Dessesaure, 
    429 F.3d 359
    , 367
    (1st   Cir.    2005).      The   district       court   determined   that    the
    requirements of the independent source doctrine were satisfied,

    v. Patane, 
    542 U.S. 630
    , 641-42 (2004)). Neither the government
    nor the district court relied on this doctrine during the
    proceedings below, and we do not explore its ramifications on
    appeal.

    We start with the officers' decision to obtain the
    warrant.     The question of an officer's subjective intent to pursue
    a warrant depends on the totality of the circumstances.                                    See
    Dessesaure, 
    429 F.3d at 369
    .               Although "after-the-fact assurances"
    by an officer regarding his intent may be probative, an inquiring
    court   is   not     bound     by    such    assurances        if    the    officer     lacks
    credibility        or     if   objective       factors     render          his   assurances
    "implausible."

    Here,       Pappas's     testimony        made     clear       that    once    he
    detained     the        appellant     in    the      parking    lot,        searching      the
    appellant's room was his obvious next step.                         See United States v.
    Rivera, 
    825 F.3d 59
    , 65 (1st Cir.) (explaining that "common sense
    indicates that a drug pusher would want to hide . . . drug-
    connected things" in a place that was safe and easy to access,
    "like a house"), cert. denied, 
    137 S. Ct. 522
     (2016).                              As Pappas
    told the district court, his "training and experience" led him to
    believe that a hotel room being used as the base for a drug-
    trafficking operation — such as the appellant's — was likely to
    contain "drugs, proceeds and weapons."                    Pappas further explained
    why, without reference to what the appellant said while under
    arrest, he believed that, "more likely than not," drugs were in
    the appellant's room.               At the same time, he voiced his concern
    that "somebody . . . could possibly be destroying evidence."
    Absent consent, he planned to seek a warrant to search room 131 as
    - 18 -
    soon as he "secured" the room.      The district court supportably
    credited this testimony.
    In any event, the court had more to go on than Pappas's
    bare assurances.    The record is replete with evidence that —
    certainly no later than the time of the appellant's arrest — the
    officers would have sought such a warrant, come what may. We offer
    a representative sampling of this evidence.
    To begin, the officers had their eye, quite literally,
    on room 131 from virtually the time that they first arrived at the
    hotel.   Among other things, the front-desk manager told them of
    her suspicions about room 131 and relayed that a New York address
    was used in renting the room; that room 131 was the only room in
    the hotel that had been paid for in cash; and that the occupants
    (after first being assigned a different room on a higher floor)
    asked to move and wound up in a ground-level room, near an exit.
    That the officers had by then focused on room 131 is adequately
    evinced by the fact that they sought (and obtained) a neighboring
    room so that they could watch room 131.
    Given the apparently reliable tip and the front-desk
    manager's comments about the number of visitors to room 131, Pappas
    had very good reason to believe that the sale he had witnessed was
    not an isolated incident.    Similarly, he had good reason to think
    that evidence of the drug enterprise was apt to be found in the
    appellant's hotel room.    See United States v. Barnes, 
    492 F.3d 33
    ,
    - 19 -
    37 (1st Cir. 2007) (finding probable cause to search a residence
    when defendant sold drugs shortly after leaving the residence);
    United States v. Ribeiro, 
    397 F.3d 43
    , 49-50 (1st Cir. 2005)
    (same).
    Struggling to parry this thrust, the appellant contends
    that if he had not told Pappas he was staying in room 131 and had
    his keycard not opened the door to that room, Pappas would not
    have known which room was his.6   This contention blinks reality:
    it ignores a multitude of facts that corroborate the officers'
    belief, already formed at the time of the de facto arrest, that
    the drug-traffickers (including the appellant) were likely staying
    in room 131.
    For instance, the drug transaction that Pappas witnessed
    took place near the hotel exit most proximate to room 131; he knew
    that the appellant was a guest at the hotel because the appellant
    had imparted that information when, prior to the de facto arrest,
    Pappas offered to hold the outside door so that the appellant could
    re-enter the premises; and the appellant roughly matched the
    physical description that the front-desk manager had provided
    6  The appellant informed Pappas which room was his after the
    de facto arrest had occurred. Pappas thereafter used the keycard
    that he had taken from the appellant's person to open the door to
    room 131 without the appellant's consent. Assuming the absence of
    exigent circumstances, see supra note 4, that intrusion violated
    the appellant's Fourth Amendment rights, see United States v. Bain,
    
    874 F.3d 1
    , 14-15 (1st Cir. 2017).

    regarding an occupant of room 131.      Indeed, the fact that the
    officers had placed room 131 under surveillance before any of the
    relevant events transpired in the parking lot is itself a strong
    indication that the police believed that room to be the hub of the
    criminal enterprise.    On this record, we conclude that, after
    stripping the excludable evidence from Pappas's affidavit, the
    district court did not err — let alone clearly err — in finding
    that what remained demonstrated that the officers had ample reason
    to think that the appellant was staying in room 131.   So, too, we
    conclude that the district court did not err — let alone clearly
    err — in determining that the officers' decision to obtain a search
    warrant for room 131 preceded both the appellant's de facto arrest
    and their initial (warrantless) entry into those premises.
    The question persists, of course, as to whether the
    warrant affidavit contained sufficient facts to support probable
    cause even after excising the appellant's pre-Miranda statements
    and any knowledge gleaned during the initial (warrantless) entry
    into room 131.   In assaying the district court's response to this
    question, we remain mindful that a finding of probable cause "does
    not require proof of guilt beyond a reasonable doubt."    Almonte-
    Báez, 857 F.3d at 32.   Such a finding requires only an objectively
    reasonable basis for believing "that evidence of [the crime] can
    likely be found at the described locus at the time of the search."
    United States v. Floyd, 
    740 F.3d 22
    , 32 (1st Cir. 2014) (quoting
    - 21 -
    United States v. Ricciardelli, 
    998 F.2d 8
    , 10 (1st Cir. 1993)).
    This "nexus between enumerated evidence of the crime and the place
    'can be inferred from the type of crime', the nature of the items
    sought, the extent of an opportunity for concealment and normal
    inferences as to where a criminal would hide [evidence of a
    crime]."   United States v. Rodrigue, 
    560 F.3d 29
    , 33 (1st Cir.
    2009) (quoting Ribeiro, 
    397 F.3d at 49
    ).
    We    have   scant   difficulty    in   concluding     that,   after
    excising the offending facts from the affidavit, it still contained
    more than enough information to support a finding that evidence of
    drug trafficking would likely be found in room 131.                 See Floyd,
    740 F. 3d at 32.    The affidavit described the informant's tip, why
    that tip was thought reliable, the front-desk manager's comments,
    the   apparent    hand-to-hand     drug     transaction,    and     the   facts
    undergirding     Pappas's   objectively      reasonable    belief    that   the
    appellant was staying in room 131.           Even without the excludable
    evidence, what remained in the affidavit was sufficiently cogent
    to sustain a finding of probable cause and, thus, to justify the
    issuance of the warrant. Employing the independent source doctrine
    and undertaking de novo review of the district court's ultimate
    probable cause determination, see Ornelas, 
    517 U.S. at 699
    , we
    decry no error in the court's refusal to suppress the fruits of
    the warrant-backed search.
