    APPEAL FROM THE UNITED STATES DISTRICT COURT
    FOR THE DISTRICT OF MASSACHUSETTS

    Lynch, Chief Judge,

    LIPEZ, Circuit Judge.        Jake Crooker was charged with
    possession of firearms and ammunition by an unlawful user of a
    controlled substance, in violation of 
    18 U.S.C. § 922
    (g)(3), and
    possession of marijuana, in violation of 
    21 U.S.C. § 844
    .             After a
    jury trial, Crooker was convicted of possession of marijuana and
    fined $4000.       He now appeals the district court's denial of his
    motion to suppress statements and evidence recovered during the
    July     15,    2004,   search   of   62    Joseph   Avenue   in   Westfield,
    Massachusetts, where he resided with his parents and brothers.
    Crooker argues that the search warrant was not supported by
    probable cause and was a defective general warrant that did not
    state with particularity the items to be seized.               Moreover, he
    alleges that the agents executing the warrant exceeded its scope.
    He also argues that the statements admitted against him were made
    during custodial interrogations without the benefit of Miranda
    warnings.      We affirm.
    I.
    When reviewing the denial of a motion to suppress, we
    rehearse the facts as supportably found by the court below,
    including any inferences drawn by the court from the discerned
    facts.    United States v. Pontoo, 
    666 F.3d 20
    , 24 (1st Cir. 2011).
    Here, we draw from the district court's bench decision, issued
    after a hearing on Crooker's motion to suppress, as well as the
    -2-
    affidavit     supporting    the     search    warrant       and   other    hearing
    testimony.
    A.    Factual Background
    The relevant series of events was triggered by an ongoing
    Federal Bureau of Investigation ("FBI") investigation of Crooker's
    uncle, Michael Crooker.1       The application and affidavit in support
    of a warrant to search the buildings and grounds of 62 Joseph
    Avenue, Crooker's residence, were submitted by FBI Special Agent
    Richard Winfield.       The documents primarily described the FBI's
    evidence against Michael, who does not live at 62 Joseph Avenue.
    The evidence suggested that Michael was involved in the unlawful
    manufacture,    storage,      and   interstate     shipping       of    explosives,
    biological toxins, and weapons.         Although Michael did not live at
    62 Joseph Avenue, Winfield's affidavit stated that the FBI had
    reason to believe that Michael had buried ricin near a stump in his
    brother Stephen's (and Crooker's) backyard at 62 Joseph Avenue.2
    The warrant application included an attachment detailing the items
    the   government   sought     to    seize    during   the    search,      including
    specified    firearms   and    evidence      of   explosives      and    biological

    Because many of the parties share a last name, first names
    will be used. Any use of "Crooker" alone refers to Jake Crooker.
    Crooker's father is Stephen Crooker, and his uncles are Michael and
    Peter Crooker.

    Ricin is a deadly toxin derived from castor beans. A few
    grains, if injected, inhaled, or ingested, can kill an adult.
    -3-
    weapons violations, as well as evidence related to those violations
    stored on one or more computers.
    On July 14, 2004, a warrant was issued to search the
    grounds and residence at 62 Joseph Avenue for
    evidence, fruits or instrumentalities of the
    manufacturing of explosive materials without a
    license, in violation of Title 18, United
    States Code, Section 842(a)(1); shipping,
    transporting or receiving any explosive
    materials in interstate commerce, in violation
    of Title 18, United States Code, Section
    842(i);   illegal    storage   of    explosive
    materials, in violation of Title 18, United
    States Code, Section 842(j); and possession
    and manufacture of biological weapons in
    violation of Title 18, United States Code,
    Section 175.
    The warrant did not incorporate the affidavit or the list of items
    to be seized.      Thus, the warrant did not authorize seizure of
    firearms, ammunition, drugs, or drug paraphernalia.     See Groh v.
    Ramirez, 
    540 U.S. 551
    , 557-58 (2004) (stating that a warrant
    authorizes only the seizure of items described with particularity
    on the face of the warrant or in documents explicitly incorporated
    in the warrant).
    Agents from the FBI and the Bureau of Alcohol, Tobacco,
    Firearms and Explosives ("ATF") and local police executed the
    search warrant on the afternoon of July 15, 2004.   A team of agents
    consisting of between four and eight men led by FBI Special Agent
    Mark Karangekis (the "entry team") entered and cleared the house.
    They were clad in black clothing and FBI attire and ran up the lawn
    -4-
    single file with their weapons drawn.        Karangekis knocked at the
    front screen door and announced the agents' purpose. After Crooker
    exited the house and chained up one of his dogs at the agents'
    request, the entry team went into the house and began clearing it.3
    After the house had been cleared, the "search team" led by FBI
    Special   Agent   Robert   Lewis   entered   the   house.   Lewis   was
    responsible for coordinating the search, taking custody of seized
    evidence at the conclusion of the search, and maintaining contact
    with the individuals whose house was being searched.
    During the multiple hour search, Lewis and Springfield
    Police Officer Ronald Sheehan had a conversation with Crooker in
    front of the house.   At the beginning of the interaction, Sheehan
    frisked Crooker and seized a cigarette pack that held a bag
    containing a green leafy substance.4         The agents did not arrest
    Crooker or advise him of his Miranda rights, but instead asked him
    to consent to questioning.     The conversation began in the front
    yard and, due to the heat, at least some part of the conversation
    occurred in Lewis's air-conditioned car.       During the conversation,
    Crooker told the agents that there were four safes in the house -
    3
    Karangekis testified that he entered before Crooker removed
    the dog and that the rest of the entry team came in after the dog
    was secured. The discrepancy does not change our analysis.
    4
    The parties disagree about the location on Crooker's person
    of the cigarette pack. Lewis testified that he saw Sheehan take
    the pack from Crooker's hand. Crooker testified that Sheehan took
    the pack out of his front left jeans pocket.
    -5-
    Crooker had access to two, which contained his and his mother's
    weapons,    and   his   father   had   access   to   the   other   two,   which
    contained antique firearms.5       Lewis testified that he knew at the
    time of the search that the warrant did not authorize seizure of
    firearms or ammunition.      Nevertheless, Lewis asked Crooker to open
    the two safes to which Crooker had access, and agents seized
    several weapons and ammunition from inside the safes. Lewis stated
    that he seized the weapons because he knew that: (1) Stephen
    Crooker's prior felony conviction made his possession of weapons
    and ammunition unlawful and he was unsure whether Stephen had
    access to the items, and (2) Crooker had confessed to using illegal
    drugs, making his possession of firearms unlawful.
    Later in the search, ATF Special Agents Michael Curran
    and Debora Seifert interacted with Crooker, who was cooperative and
    again described the family members' varied access to the four
    safes.     Crooker also mentioned that there was an unlocked tackle
    box containing ammunition that belonged to him in the living room.6
    When Curran asked Crooker if he used drugs, Crooker said that he
    occasionally used marijuana and that there was some marijuana
    inside the house that belonged to him.          Agents then seized bags of
    5
    Individuals previously convicted of felonies may lawfully
    possess "antique firearms" as defined in 
    18 U.S.C. § 921
    (a)(16).
    6
    Crooker refers to the box as a tackle box, while the
    government calls it a toolbox. The distinction is not relevant,
    and we refer to it throughout as a tackle box.
    -6-
    what appeared to be marijuana from the kitchen and basement.    The
    tackle box containing ammunition and a cigarette rolling device was
    seized, along with all of its contents.        Curran and Seifert
    testified that, although they knew that Crooker had a valid state
    license to possess firearms, they considered him a user of illegal
    narcotics, and thus it was unlawful for him to possess the weapons
    and ammunition.
    B.   Procedural History
    After he was indicted, Crooker moved to suppress the
    statements he made during the search as well as various physical
    evidence seized that day. Crooker argued, among other things, that
    Winfield's affidavit failed to establish probable cause for the
    issuance of the warrant; the search exceeded the scope of the
    warrant; the plain view exception did not apply to seizure of
    various pieces of evidence; and he was subject to custodial
    interrogation without being advised of his Miranda rights.     After
    the district court denied the motion to suppress, Crooker was tried
    for unlawful possession of marijuana and possession of firearms and
    ammunition while using illegal narcotics.       The jury convicted
    Crooker on the marijuana charge and acquitted him of the firearm
    charge.   The court imposed a $4000 fine.   Crooker now appeals the
    district court's denial of his motion to suppress. In so doing, he
    both repeats grounds he argued below and challenges for the first
    time the particularity of the warrant.   Although his particularity
    -7-
    claim is presented for the first time on appeal, he argues that the
    claim was forfeited - not waived - and thus is entitled to plain
    error review.
    II.
    A.   Motion to Suppress Tangible Evidence
    In support of his appeal, Crooker argues that (1) the
    warrant was not properly supported by probable cause, (2) the
    agents executing the search exceeded the scope of the warrant, and
    (3) the warrant lacked the particularity required by the Fourth
    Amendment.        When reviewing a denial of a motion to suppress, we
    review the district court's factual findings for clear error, and
    its legal conclusions (for example, that a given set of facts
    constituted probable cause) de novo.             United States v. McMullin,
    
    568 F.3d 1
    , 5 (1st Cir. 2009).            "A clear error exists only if,
    after considering all of the evidence, we are left with a definite
    and firm conviction that a mistake has been made," and "we will
    uphold a district court's decision to deny a suppression motion
    provided that any reasonable view of the evidence supports the
    decision."        
    Id.
     (quoting United States v. Woodbury, 
    511 F.3d 93
    ,
    96-97 (1st Cir. 2007)) (internal quotation marks omitted).
    1.    Probable Cause for the Issuance of the Warrant
    As    he   did   below,   Crooker   argues   that   "[t]here   was
    absolutely no probable cause to believe that evidence of a crime
    would be found in the residence at 62 Joseph Avenue," and that
    -8-
    there was no nexus between the residence and the crimes committed
    by his uncle Michael.   As Crooker puts it, "[t]he only and tenuous
    link to 62 Joseph Avenue, that Michael Crooker hid a handful of
    ricin by a stump in the backyard, came from an untrustworthy
    jailhouse informant with prior convictions for fraud."      Crooker
    argues that this information was insufficient to provide a reason
    to believe that there was contraband related to explosives or
    biological agents in his backyard.    Moreover, he argues that even
    if there were reason to believe contraband might be found in the
    backyard, there was no reason to believe contraband would be found
    inside the house.
    In response to the government's evidence, the district
    court concluded in a bench decision that the warrant was supported
    by probable cause. In so doing, the court relied on information in
    the Winfield affidavit, noting that it had been clearly shown that
    Michael was "involved in the production of explosives and very
    dangerous materials" and various evidence tied those materials to
    Crooker's house.    For example, a prisoner at the Hampden County
    Correctional Facility ("CI-2")7 told agents that Michael told him
    that a handful of ricin was buried near a tree stump in Crooker's
    yard.8   The court noted that although CI-2's word alone would be
    7
    Our use of "CI-1" and "CI-2" corresponds with the parties'
    use of those labels in their briefs.
    8
    Michael was arrested on June 23, 2004, pursuant to a warrant
    and imprisoned in the Hampden County Correctional Facility. On
    -9-
    unreliable, much of the information he provided was corroborated by
    Special Agent Winfield.9   The district court also relied on a phone
    call between Stephen and Michael that was described in the Winfield
    affidavit.10   During that call, Stephen and Michael discussed "R"
    and how to use Michael's "R" as a plea negotiating tool.11     Agent
    Winfield believed "R" to be a reference to ricin.    From this phone
    call, the court found that "it was clear that the two of them were
    speaking to some extent in code, which suggests that they had
    information that they did not want others to easily understand, and
    that the material was of sufficient importance and potency that it
    was a bargaining chip in the negotiations with the government."
    Moreover, according to a former friend of Michael's ("CI-1"),
    Michael had recently moved his poisons and explosives lab to
    Crooker's grandfather's house.      Michael showed CI-1 the lab,
    July 13, 2004, he was indicted for shipping a firearm in interstate
    commerce, in violation of 
    18 U.S.C. § 922
    (g).
    9
    For example, Winfield verified the addresses and unlisted
    phone numbers that CI-2 said Michael had given him for Stephen and
    Peter Crooker, so that CI-2 could contact them on Michael's behalf
    when CI-2 was released from jail. CI-2 also stated that Michael
    told him he had access to a National Car Rental ("NCR") facility in
    Connecticut. According to Winfield, by mid-June 2004, Michael had
    stolen approximately 27 vehicles from NCR.
    10
    This phone call was recorded by officials at the Hampden
    County Correctional Facility where Michael was being held at the
    time of the call.
    11
    We do not know how Michael and Stephen   thought that Michael
    might use the ricin as a plea negotiating       tool.   The Winfield
    affidavit does not elaborate, and the record    does not contain the
    full content of the call between Michael and    Stephen.
    -10-
    pointing out where he made and kept explosives.                  Michael also told
    CI-1 that he had buried a MAC 10 gun but could not find it and had
    buried various gun parts in ammunition cans.                       Michael did not
    specify to CI-1 where the MAC 10 or gun parts were buried.                      Also,
    according to CI-2, Michael hid ricin in two locations other than
    Stephen's backyard.         Based on this evidence, the district court
    concluded that "it would have been irresponsible for the government
    not to make an effort to recover this very dangerous material from
    the location [in] which they had probable cause to believe they
    would find it."
    We   agree    with    the     district    court's      analysis.     The
    government had specific information from a confidential informant
    that ricin was buried in Crooker's backyard, and that Michael hid
    various weapons and biological agents in numerous locations and
    moved those items around to avoid detection.                 This information was
    the backdrop for additional information that the government had
    from recorded phone conversations between Michael and Stephen,
    notably Michael and Stephen's discussion in coded language about
    ricin and its value in Michael's plea negotiations with the
    government. In another discussion, Stephen and Michael referred to
    unidentified property belonging to Michael, noting that Crooker's
    grandfather       had   moved    it   to    an    undisclosed      location.     This
    information was supplemented by information from a confidential
    informant,    who       stated    that     Michael    kept   his    explosives    lab
    -11-
    equipment    and       supplies   as    well     as   ammunition   in    Crooker's
    grandfather's basement and shed. In light of Stephen and Michael's
    secretive conversations about the biological toxin ricin, their
    discussion about moving Michael's possessions while Michael was
    incarcerated, and information provided by confidential informants -
    including information that Michael had buried ricin in Crooker's
    backyard, there was probable cause to believe that evidence of the
    enumerated crimes would be found at Crooker's house.                 Accordingly,
    the district court did not err in denying Crooker's motion to
    suppress on probable cause grounds.
    2.     Scope of the Search
    Crooker alleges that the seized tackle box, on which
    marijuana residue was found, and its contents, including the seized
    ammunition       and    cigarette      rolling    device,   should      have   been
    suppressed.12      He argues that the seizure of the tackle box and its
    contents was beyond the scope of the warrant because the warrant
    only authorized the seizure of evidence related to explosives and
    biological weapons.         The warrant did not incorporate the list of
    items to be seized submitted with the affidavit.                   Thus, Crooker
    argues, any seizure of drugs or drug paraphernalia was unlawful.
    12
    In his motion to suppress, Crooker also argued that the
    seized guns should be suppressed because their recovery was beyond
    the scope of the warrant. Crooker's claims with respect to the
    guns and ammunition are moot on appeal. Crooker was acquitted of
    the weapons charge at trial.
    -12-
    In the alternative, Crooker argues that, even if some
    contents of the tackle box could have been seized under the plain
    view exception to the warrant requirement, the agents were required
    to separate out the items with immediately apparent evidentiary
    value and leave behind those items that were not immediately
    identifiable as contraband or evidence of a crime.                Specifically,
    he argues that the agents should have removed the loose ammunition
    and rolling device from the tackle box and left the box and the
    remainder of its contents in the house.
    The district court concluded that the search and seizure
    of the tackle box did not exceed the scope of the warrant.              Because
    the warrant authorized the agents to search for evidence of
    biological weapons, including small amounts of ricin powder, the
    agents could legitimately open every container in the house to find
    those items.     The agents opened the tackle box to search for items
    covered   by    the   warrant,   and,    once   the   box   was    opened,   the
    contraband items not covered by the warrant were in plain view.
    We agree.     In general, "any container situated within
    residential premises which are the subject of a validly-issued
    warrant may be searched if it is reasonable to believe that the
    container   could     conceal    items   of   the   kind    portrayed   in   the
    warrant."      United States v. Rogers, 
    521 F.3d 5
    , 9-10 (1st Cir.
    2008) (quoting United States v. Gray, 
    814 F.2d 49
    , 51 (1st Cir.
    1987)) (internal quotation mark omitted). The warrant in this case
    -13-
    permitted agents to search for items as small as grains of powder.
    Thus, the agents had a right to search the tackle box.                       While
    lawfully searching the tackle box, agents saw what they believed to
    be contraband and evidence of a crime - ammunition and a cigarette
    rolling device.
    A law enforcement agent may, without a warrant, seize an
    object in plain view so long as he or she has (1) lawfully reached
    the vantage point from which he sees the object, (2) has a right of
    access to the object itself, and (3) has probable cause to support
    his seizure of that object. United States v. Paneto, 
    661 F.3d 709
    ,
    713 (1st Cir. 2011).          In this case, the agents satisfied the first
    requirement - lawfully reaching the vantage point from which they
    saw the ammunition and rolling device - because they were in the
    house pursuant to a warrant supported by probable cause.                Second,
    as discussed, the warrant permitted agents to search for items as
    small as grains of powder.            Thus, the agents had a right to access
    and open the tackle box.         Once inside the tackle box - recognizing
    that both Jake and Stephen Crooker were unable to lawfully possess
    ammunition      -    the   officers     had   probable   cause   to   seize    the
    ammunition, satisfying the third plain view requirement. Moreover,
    the   rolling       device,   which    agents   believed   was   used   to    roll
    marijuana cigarettes, was in plain view within the tackle box and
    its value as evidence of illegal activity was immediately apparent.
    -14-
    Thus, the ammunition and rolling device were properly seized
    pursuant to the plain view doctrine.
    With regard to Crooker's alternative argument, we need
    not decide whether the agents acted reasonably in seizing the
    entire tackle box instead of separating out the loose ammunition
    and rolling device and leaving the tackle box behind.     The only
    item of evidentiary value that resulted from the seizure of the
    tackle box was trace marijuana residue.    The government presented
    a wealth of other evidence supporting its allegation that Crooker
    possessed marijuana, including (1) three bags of leafy green
    substance recovered from different areas of the house, (2) the
    cigarette rolling device, (3) a bag of leafy green substance
    recovered from a cigarette pack on Crooker's person, and, most
    notably, (4) Crooker's confession that he used and possessed
    marijuana.     Ignoring the residue completely, the evidence was
    sufficient to demonstrate that Crooker possessed marijuana.   Thus,
    even if it was impermissible for agents to seize the entire tackle
    box and later examine it for residue, admission of that residue was
    harmless error. See United States v. Jiménez, 
    419 F.3d 34
    , 42 (1st
    Cir. 2005) (finding harmless error where erroneously admitted
    evidence "pales in light of the other evidence introduced at
    trial," including defendant's confession to the charged offense).
    -15-
    3.     The Warrant's Particularity
    Crooker argues for the first time on appeal that the
    warrant lacked sufficient particularity to satisfy the requirements
    of the Fourth Amendment because it did not specifically describe
    the things to be seized. Instead, it only permitted the seizure of
    "evidence, fruits, or instrumentalities" of violations of four
    enumerated statutory provisions.            Although he failed to timely
    raise this objection prior to trial pursuant to Federal Rule of
    Criminal Procedure 12(b)(3)(C), Crooker claims that the language in
    Rule 12(e) stating that "[a] party waives any Rule 12(b)(3)
    defense, objection, or request not raised by the deadline" means
    that such arguments are forfeited, not waived.           See Fed. R. Crim.
    P. 12(e).    Hence, he says he is entitled to plain error review of
    his particularity argument.
    In United States v. Walker, 
    665 F.3d 212
    , 227-28 (1st
    Cir. 2011), where there was a failure to challenge a defect in an
    indictment under Rule 12(b)(3)(B), we rejected the argument that
    the waiver language in Rule 12(e) means forfeiture: "Rule 12(e)
    says what it means and means what it says" when it states that a
    12(b)(3) defense not raised before trial is waived.               Walker,

    .     Crooker   argues   that   the   difference    between   a
    defective    indictment    and   a   ground    for   suppression     warrants
    different treatment of the distinct 12(b)(3) claims under Rule
    12(e). He cites language from Walker in support of this position:
    -16-
    [T]he matters that fall within the compass of
    Rule 12(b)(3) (and thus Rule 12(e)) are
    normally    correctable   before    trial   if
    seasonably brought to the attention of the
    district court and the government. It strikes
    us as manifestly unfair for a defendant to sit
    silently by, take his chances with the jury,
    and then be allowed to ambush the prosecution
    through a post-trial attack. Accordingly, we
    join the majority view and hold that a failure
    to challenge a defect in an indictment before
    trial, as required by Rule 12(b)(3), results
    in an unreviewable waiver of that challenge
    pursuant to Rule 12(e).
    Walker, 
    665 F.3d at 228
    .
    Unlike a defective indictment, Crooker asserts, the
    government cannot fix suppression matters prior to trial.                  Here,
    for example, the government could not correct any particularity
    defects in the warrant. Moreover, Crooker says that he did not sit
    silently by and later ambush the prosecution.             Instead, he filed a
    pre-trial motion to suppress, albeit on other grounds.                 He insists
    that "[a]lthough the government may not always have the incentive
    to present all of the facts if an issue is not raised below, if an
    issue   can    be   resolved   on    the   record    before    this   Court,   the
    government is not prejudiced by the initial failure to raise the
    issue and review for plain error is warranted."
    The government argues that it could indeed be prejudiced
    by a defendant's failure to timely raise a ground for suppression.
    If   appellate      review   of     that   omitted    ground    is    successful,
    convictions may be vacated even though the government may have had
    other evidence of guilt that, with proper notice, could have been
    -17-
    introduced at trial.     Furthermore, the timely presentation of
    suppression claims to the district court allows full development of
    the factual record and permits the government to appeal any adverse
    suppression decision prior to trial.
    We agree with the government's position.   There is the
    potential for both unfairness to the government and needless
    inefficiency in the trial process if defendants are not required,
    at the risk of waiver, to raise all of their grounds in pursuing a
    motion to suppress.   Hence, the reasoning of Walker on the import
    of the waiver language of Rule 12(e) applies as well to the failure
    to include a particular ground in a motion to suppress. Of course,
    as we noted in Walker, defendants are not without recourse.   If a
    defendant can show "good cause" for failing to timely raise a
    12(b)(3) challenge, that challenge "may be entertained by the
    district court and reviewed on appeal."   Walker, 
    665 F.3d at 228
    ;
    see also Fed. R. Crim. P. 12(e).
    Crooker argues that his trial counsel's failure to raise
    the particularity issue in the motion to suppress amounted to
    ineffective assistance of counsel, which in turn constituted good
    cause.   We need not decide whether the government is correct that
    a defendant must bring his good cause argument to the attention of
    the district court before having it reviewed by this court.   Even
    assuming arguendo that a good cause argument can be raised for the
    first time on appeal, and further assuming that a successful
    -18-
    ineffective assistance of counsel claim could constitute good
    cause, we would not be able to review Crooker's ineffective
    assistance     of   counsel      claim    because      the    record     here    is
    insufficiently developed.         See, e.g., United States v. Rodriguez,
    
    675 F.3d 48
    , 56 (1st Cir. 2012) ("It is only in exceptional cases
    when there are no 'critical' facts in dispute and the record has
    been sufficiently developed that we will address an ineffective
    assistance of counsel claim on direct appeal.").

    , 6 (1st Cir. 2011) (internal citation omitted); see also
    Miranda v. Arizona, 
    384 U.S. 436
     (1966).               To determine whether a
    person was in custody for Miranda purposes, the district court
    looks   to    the   circumstances       surrounding     the     questioning     and
    determines "whether those circumstances would cause a reasonable
    person to . . . underst[and] his situation to be comparable to a
    formal arrest."     Guerrier, 669 F.3d at 6.           "Several factors guide
    this    analysis,    including      '(without        limitation)       where    the
    questioning    occurred,    the    number      of   officers,    the   degree   of
    physical     restraint,    and    the    duration     and    character    of    the
    interrogation.'"      Id. (quoting United States v. Teemer, 
    394 F.3d 59
    , 66 (1st Cir. 2005)).          We review a district court's factual
    determinations about the circumstances surrounding the questioning
    -19-
    for clear error, and its legal conclusion about a reasonable
    person's understanding of those circumstances de novo.           United
    States v. Hughes, 
    640 F.3d 428
    , 435 (1st Cir. 2011).
    Crooker alleges that law enforcement agents failed to
    advise him of his Miranda rights, but nevertheless subjected him to
    a series of custodial interrogations on the day of the search.
    Crooker argues that he was interrogated on more than one occasion
    and that, under the totality of the circumstances, a reasonable
    person in his situation would not have felt free to leave.          He
    notes   that   the   environment     was   "police-dominated,"     with
    approximately thirty officers present during the execution of the
    search warrant, some of whom "forced [him] outside, at gunpoint,
    and searched him."   He claims that he was escorted and followed by
    agents and that soon after being searched by the entry team, he was
    again frisked by other agents.     He adds that the fact that he asked
    agents if he could leave illustrates that a reasonable person in
    those circumstances would not have felt free to leave.      Moreover,
    he points to the testimony of Agent Curran, who stated that at the
    time of the search, he was unsure if Crooker was free to leave.
    Because he was subjected to custodial interrogations without the
    benefit of Miranda warnings, Crooker insists that the statements
    admitted against him should have been suppressed.
    The district court disagreed.     It found that the agents'
    interactions with Crooker were consensual – the officers asked
    -20-
    Crooker if they could talk to him and noted that there was "no
    testimony that there were any weapons drawn, any shouting, any use
    of profanity."    The court found that Crooker freely walked around
    the property and that the officers were "fairly calm and polite and
    accommodating." The district court determined that "[t]here was no
    evidence that there was any imposition of any custody on Mr. Jake
    Crooker at the time of the conversations.          This was simply not a
    custodial   interrogation,    Miranda     didn't   apply,   and    Mr.   Jake
    Crooker's statements were all perfectly voluntary and knowing and
    intelligent."
    Our review leads to the same conclusion.            Crooker was
    questioned in familiar surroundings where, in general, questioning
    tends to be significantly less intimidating than questioning in
    unfamiliar locations.      See Hughes, 
    640 F.3d at 435-36
     ("Though
    questioning in a suspect's dwelling may at times comprise a
    custodial interrogation, such a location generally presents a less
    intimidating atmosphere than, say, a police station." (internal
    citation omitted)).    Although there were numerous officers on the
    property, those officers holstered their guns after the entry team
    cleared the house and left them holstered throughout the afternoon-
    long search.     Cf. 
    id. at 436
     (finding no custody where visible
    weapons remained holstered throughout visit to suspect's home).
    Moreover, although those officers were present inside and around
    Crooker's    house,   no   more   than    two   agents   were     in   direct
    -21-
    conversation      with       Crooker    at    one    time.       Crooker    was   never
    physically      restrained,      and,    in    fact,     moved    freely    about   his
    property throughout the search, even leaving the property for some
    time after he was questioned.                See 
    id.
     (finding no custody where
    there was no "meaningful physical restraint" and any police escort
    was not so pervasive and close "as to intrude upon any intimate
    moment    or    private       activity").           By   all   accounts,    Crooker's
    interactions with the agents were cooperative and relatively brief.
    See Guerrier, 669 F.3d at 6 (finding no custody where interview
    atmosphere was "relatively calm and nonthreatening" and interview
    lasted approximately 20-25 minutes, "a relatively short time").
    Given   the    familiarity      of    the     surroundings    in   which
    Crooker was questioned, the calm and peaceable nature of the
    conversations between Crooker and agents, and the lack of physical
    restraint or show of force during questioning, we conclude that
    Crooker was not in custody for Miranda purposes. Thus, the agents'
    failure   to     advise      Crooker    of    his    Miranda     rights    was    not   a
    constitutional violation, and the district court did not err by
    denying Crooker's motion to suppress his statements.
    Affirmed.
