    SUMMARY *
    Criminal Law
    The panel affirmed the district court’s denial of
    Demetrius Verardi Ramos’s motion to suppress his post-
    arrest statements in a case in which a jury convicted Ramos
    of one count of conspiracy to transport, for profit,
    noncitizens who have entered or remain in the United States
    unlawfully; four counts of harboring such noncitizens for
    profit; and three counts of transportation of such noncitizens
    for profit.
    Ramos argued that his statements were involuntary
    because, just prior to the interrogation, an agent had shown
    him a plastic baggie containing drugs and threatened him
    with drug charges if he did not cooperate. After holding an
    evidentiary hearing, a magistrate judge issued a report
    recommending that the district court deny the motion to
    suppress.
    The panel held that the district court did not abuse its
    discretion by wholly adopting the magistrate judge’s report
    and recommendation. The panel wrote that the district court
    did what the Federal Magistrates Act requires: it indicated
    that it reviewed the record de novo, found no merit to
    Ramos’s objections, and summarily adopted the magistrate
    judge’s analysis in his report and recommendation. The
    panel emphasized that this court presumes that district courts
    conduct proper de novo review where they state they have
    done so, even if the order fails to specifically address a

    party’s objections. Rejecting Ramos’s assertion that the
    district court’s “bare assertion” that it reviewed de novo is
    insufficient because the order was “mere boilerplate” and
    failed to address his specific objections, the panel noted that
    the district court asserted it conducted de novo review not
    only in its order adopting the magistrate judge’s report and
    recommendation, but also in its order denying the motion for
    reconsideration. More importantly, the district court had no
    obligation to provide individualized analysis of each
    objection. Because the district court said it independently
    reviewed the record and there is no evidence indicating
    otherwise, the panel had no reason to second-guess its
    assertion of de novo review.
    On the merits, Ramos contended that the district court
    erred in denying the motion to suppress because it
    mistakenly adopted the magistrate judge’s “improper
    speculation regarding the contents of the baggie shown to”
    Ramos when he was detained. The panel disagreed. The
    magistrate judge did not, nor was he required to, make a
    proposed finding about the baggie; rather, he only had to
    consider whether Ramos’s “will was overborne” under the
    totality of the circumstances. The panel wrote that, after
    observing the implausibility of Ramos’s testimony and
    considering Ramos’s verbal and signed Miranda waiver,
    age, education level, and fluency in English, the magistrate
    judge properly recommended finding the statements made
    during the interrogation voluntary. Moreover, the panel
    could not hold that the magistrate judge was wrong to reject
    Ramos’s testimony, as the report and recommendation
    provided ample reason to find Ramos not credible, and the
    rest of the record supports the magistrate judge’s
    analysis. The video footage does not clearly show the
    contents of the baggie, and two agents denied ever
    4                  UNITED STATES V. RAMOS
    threatening Ramos. Because there are two permissible
    views of the evidence, the magistrate judge’s choice between
    them, with which the district court agreed, cannot be clearly
    erroneous.
    The panel addressed Ramos's challenges to the denial of
    his motion to suppress evidence on Miranda grounds and to
    a special condition of his supervised release in a
    concurrently filed memorandum disposition, in which it
    affirmed in part and vacated and remanded in part.
    Judge Collins concurred in the judgment in part and
    dissented in part. He concurred in the court's accompanying
    unpublished memorandum disposition. He dissented from
    the majority's conclusion that the district court properly
    denied the motion to suppress insofar as it was directed at
    Ramos's confession in jail after his arrest. He wrote that a
    presumption that the district court conducted a proper de
    novo review is not warranted here because (1) the magistrate
    judge’s report contains an obvious factual error concerning
    a critical issue and the error was raised in Ramos’s
    objections; (2) there are good reasons to suspect the district
    court’s order adopting the magistrate judge’s report here is,
    for all practical purposes, a 4½-page rubberstamp; (3) this
    court has previously admonished the same district judge for
    using boilerplate orders in ruling on objections to magistrate
    judges’ reports, but to no avail; (4) the underlying issue here
    is one of constitutional dimension; and (5) the panel cannot
    say that the error was harmless. He would remand with
    instructions to re-examine the matter and, if warranted, to
    grant a new trial.

    OPINION
    OWENS, Circuit Judge:
    Defendant-Appellant Demetrius Ramos appeals from his
    jury conviction and sentence for one count of conspiracy to
    transport, for profit, noncitizens who have entered or remain
    in the United States unlawfully, four counts of harboring
    such noncitizens for profit, and three counts of transportation
    of such noncitizens for profit, all in violation of 
    8 U.S.C. § 1324
    . We have jurisdiction under 
    28 U.S.C. § 1291
     and
    affirm. 1
    I. BACKGROUND
    A. Arrest and Interrogation
    On December 3, 2019, U.S. Border Patrol agents stopped
    Ramos in his vehicle in the border town of Douglas, Arizona
    and arrested him for transporting noncitizens under 
    8 U.S.C. § 1324
    . The agents placed Ramos in a holding cell after
    arriving at the Border Patrol station. While getting
    fingerprinted, Ramos asked Agent Daniel Regan to retrieve
    his prescription medication located inside his vehicle.
    Based on video footage, which contains no audio, Agent
    Robert Marrufo visited Ramos inside his holding cell at
    around 3:40 a.m. About forty minutes later, the video
    footage shows Agent Marrufo returning to the holding cell,
    showing Ramos a plastic baggie, and having a short

    We address Ramos’s challenges to the denial of his motion to suppress
    evidence on Miranda grounds and to a special condition of his
    supervised release in a concurrently filed memorandum disposition, in
    which we affirm in part and vacate and remand in part.
    UNITED STATES V. RAMOS                    7
    discussion with him. The video then shows Agent Marrufo
    leaving the cell, followed by Ramos.
    Shortly thereafter, Agents Marrufo and Jesus Barron
    conducted a Mirandized interview in an interrogation room.
    The agents encouraged Ramos to tell the truth, saying that
    “honesty goes a long way” and that “[t]here’s an old saying
    [that] the truth will set you free.” When asked about the
    events that had led up to his arrest, Ramos admitted he was
    offered $1,000 per person to transport people from Douglas
    to Phoenix but claimed that he was not aware that the
    passengers were undocumented. He also stated that he had
    transported people for pay on “many” occasions prior and
    that he was instructed to buy a separate phone for this
    purpose.
    When asked about his citizenship status, Ramos
    confirmed that he was a Brazilian citizen and had overstayed
    his visa. Ramos expressed concern for himself and his
    family, telling the agents that he “[didn’t] want to get
    deported.”
    Multiple times throughout the interrogation, Ramos
    attempted to negotiate with the agents, asking them for help
    in return for his cooperation. Ramos claimed that he knew
    “the bosses of this area” and that he was a “big piece of the
    puzzle.” He also expressed a willingness to “get further
    information” for the agents. In response to Ramos’s
    repeated attempts to cut a deal, the agents reiterated that they
    could not make any promises and that the “only thing [they
    could] do . . . is to take down the information” from the
    interrogation and relay it to someone else. Ramos asked the
    agents to “[l]et [him] talk to somebody else then.” When
    Agent Barron tried to conclude the interrogation, the
    following exchange took place:
    8                  UNITED STATES V. RAMOS
    BPA BARRON: So all the statements that
    you made today were voluntarily? Were you
    forced or coerced during your declaration?
    Did we force you to talk? Did we force you
    to say anything?
    MR. RAMOS: No, but I thought that I was
    going to get --
    BPA BARRON: All right.
    MR. RAMOS: -- something in return.
    BPA BARRON: Okay. So all the questions
    that you basically stated were voluntarily?
    SBPA MARRUFO: Yes or no?
    MR. RAMOS : I -- kind of, man, but I
    thought I was going to get something in
    return. I thought I was going to --
    SBPA MARRUFO: No. Like I -- like I told
    you, I never -- we never promised you
    anything.
    MR. RAMOS: You kind of did. You said,
    hey, man, this stuff, I’m going to take it, you
    just tell the truth.
    After the agents again reminded Ramos that they “never
    promised [him] anything,” Ramos offered to give them “all
    the information” and to wear a “bug.”
    The agents ended the interrogation at 5:14 a.m. During
    the nearly hour-long interview, no one mentioned the plastic
    baggie that Agent Marrufo had held during his second visit
    to the holding cell.
    UNITED STATES V. RAMOS                    9
    B. Motion to Suppress and Evidentiary Hearing
    After his indictment, Ramos moved to suppress, among
    other things, his statements made during the interrogation.
    He argued that his statements were involuntary because, just
    prior to the interrogation, Agent Barron had shown him a
    plastic baggie containing drugs and threatened him with drug
    charges if he did not cooperate. In its response to the motion,
    the government denied that such a conversation ever took
    place.
    The magistrate judge held an evidentiary hearing
    regarding the motion to suppress, at which the parties offered
    conflicting testimony. With regards to the events leading up
    to his arrest, Ramos testified that his friend “Gabriel” had
    offered him a flat rate of $1,000 to pick up passengers and
    take them Christmas shopping. Ramos initially testified that
    “Gabriel” asked him to take the passengers from Douglas to
    Phoenix, but later changed his story, claiming that he was
    planning on taking them to Tucson, where they would sleep
    overnight, go Christmas shopping the next morning, and
    then return to Douglas. Ramos also claimed that “Gabriel”
    provided him a separate cellphone for the job because it was
    “easier to communicate with [the] same cellphone
    company.” According to Ramos, “Gabriel” asked him to
    pick up the passengers since Uber “didn’t do that anymore
    because it’s close to the border.” When asked on cross-
    examination why he claimed to know the “bosses of this
    area” during his interrogation, Ramos testified that he had
    been exaggerating and lying to ensure that he went home that
    night.
    10                    UNITED STATES V. RAMOS
    Ramos also testified about the video footage of his
    holding cell. He claimed that Agent Barron 2 came to his
    holding cell and told him that he would have to talk to the
    agents or else it was “going to be very bad” for him.
    According to Ramos, Agent Barron promised Ramos that he
    could go home that night if he cooperated with the agents.
    Ramos also testified that, about half an hour later, Agent
    Barron returned with a plastic baggie containing a substance
    that tested positive for drugs and said that, because they
    found the baggie in Ramos’s car, they could “use it” against
    him if he did not cooperate with the agents. Immediately
    thereafter, Agent Barron allegedly asked Ramos whether he
    would be willing to talk to the agents, to which Ramos
    agreed.
    The government offered a different account of that
    evening and the plastic baggie. Without having watched the
    video footage, Agent Marrufo claimed that he—not Agent
    Barron—visited Ramos in the holding cell. Regarding the
    first interaction in the holding cell, Agent Marrufo testified
    that he went to conduct a welfare check and to verify
    Ramos’s identity after discovering that he was a Brazilian
    citizen who had overstayed his visa. Regarding the second
    interaction in the holding cell, Agent Marrufo testified that
    he did not remember having a baggie in his hand.
    Agent Barron also testified at the suppression hearing
    and claimed that he never made any threats to Ramos or
    forced Ramos to cooperate.
    2
    Ramos originally testified that Agent Barron visited him in the holding
    cell. On appeal, the parties do not dispute that the agent who visited
    Ramos was Agent Marrufo.

    C. The  Magistrate           Judge’s      Report      and
    Recommendation
    After the evidentiary hearing, the magistrate judge issued
    a twenty-page report recommending that the district court
    deny Ramos’s motion to suppress. In so recommending, the
    magistrate judge explained why he did not find Ramos’s
    testimony credible. First, the magistrate judge noted that
    Ramos contradicted himself throughout his testimony and
    “told an untenable story.” For example, Ramos initially
    testified that he was taking the passengers Christmas
    shopping in Phoenix but then later claimed they were headed
    to Tucson, where the passengers would sleep overnight and
    go shopping the next day. The magistrate judge also noted
    that Ramos’s story seemed implausible given that he did not
    have his driver’s license and was wearing hospital scrubs on
    the night of his arrest. Second, the magistrate judge
    observed that Ramos’s “demeanor was not that of an honest
    but nervous witness, but instead was that of a fabricator.”
    Third, the magistrate judge opined that Ramos’s claim that
    his confession was coerced was inconsistent with his
    demeanor and numerous attempts to negotiate with the
    agents during the interrogation.
    By contrast, the magistrate judge observed that the
    agents’ testimony credible and consistent with the
    interrogation transcript. Addressing the plastic baggie, the
    magistrate judge wrote in a footnote that “[t]he Government
    does not explain the bag, but there are alternative
    explanations. The most likely of which is that the bag
    contained medicine Defendant had requested.”             The
    magistrate judge also considered Ramos’s age, education
    level, fluency in English, over ten years of residency in the
    United States, and access to food and water the night of his
    interrogation. Based on the totality of these circumstances,
    12                  UNITED STATES V. RAMOS
    the magistrate judge recommended finding that Ramos’s
    confession was voluntary.
    Ramos timely filed objections to the magistrate judge’s
    report and recommendation. In objecting to the magistrate
    judge’s finding on voluntariness, Ramos reiterated that his
    interrogation had been coerced and argued that the
    magistrate judge had improperly speculated about the
    contents of the baggie, thereby relieving the government of
    its burden of proof.
    D. The District Court’s Orders Regarding the
    Motion to Suppress
    The district court adopted the magistrate judge’s report
    and recommendation in its entirety. In its order, the district
    court wrote, “Upon de novo review of the record and
    authority herein, the Court finds Defendant’s objections to
    be without merit [and] rejects those objections . . . .”
    In response to the district court’s order adopting the
    magistrate judge’s report and recommendation, Ramos filed
    a three-page motion for reconsideration. Without citing any
    authority, Ramos argued that the district court failed to
    conduct de novo review because the order did not discuss
    any facts or points of law. He also noted that the district
    court addressed “waiver” even though, according to Ramos,
    the case raised no waiver issue.         The motion for
    reconsideration made no mention of the baggie.
    The district court denied the motion for reconsideration,
    reiterating that it did conduct de novo review. The court
    noted that “‘[i]t is common practice among district judges
    . . . to [issue a terse order stating that it conducted a de novo
    review as to objections] . . . and adopt the magistrate judges’
    recommended dispositions when they find that magistrate
    UNITED STATES V. RAMOS                   13
    judges have dealt with the issues fully and accurately and
    that they could add little of value to that analysis.’ Garcia v.
    City of Albuquerque, 
    232 F.3d 760
     (10th Cir. 2000)”
    (alteration in original).
    E. Trial and Sentencing
    The case proceeded to trial, where Agent Marrufo was
    shown video footage of the holding cell for the first time.
    After watching the footage, Agent Marrufo testified that he
    never showed Ramos a baggie “per se” and that, if he had
    one in his hand during their conversation, he was “doing
    something else with it.” He also testified that he never
    threatened Ramos with drug charges. When asked to
    identify the bag, Agent Marrufo stated that it looked like an
    “evidence bag.” According to Agent Marrufo, he had
    handled “a lot of evidence that night” and speculated that he
    was going to drop off the evidence after visiting Ramos’s
    cell but prior to going to the interrogation room. When
    defense counsel asked Agent Marrufo to identify the “white
    stuff on the bottom of that bag,” he was unable to do so,
    claiming that he could barely see the bag, “let alone what’s
    in the bag.”
    The jury convicted Ramos on eight counts: one count of
    conspiracy to transport, for profit, noncitizens who have
    entered or remain in the United States unlawfully, four
    counts of harboring such noncitizens for profit, and three
    counts of transportation of such noncitizens for profit, all in
    violation of 
    8 U.S.C. § 1324
    . At sentencing, the district
    court imposed concurrent terms of four months in custody
    and four months of home detention. The district court also
    placed Ramos on three years of supervised release subject to
    special conditions. Ramos timely appealed.

    II. DISCUSSION
    A. Standard of Review
    We review a district court’s adoption of a magistrate
    judge’s report and recommendation for abuse of discretion.
    Brown v. Roe, 
    279 F.3d 742
    , 744 (9th Cir. 2002). “A district
    court abuses its discretion when it fails to apply the correct
    legal standard or bases its decision on unreasonable findings
    of fact.” Briseño v. Henderson, 
    998 F.3d 1014
    , 1022 (9th
    Cir. 2021) (cleaned up); see also United States v.
    Manchester Farming P’ship, 
    315 F.3d 1176
    , 1181 (9th Cir.
    2003). Under this highly deferential standard, we must
    uphold “a district court’s determination that falls within a
    broad range of permissible conclusions, provided the district
    court did not apply the law erroneously.” Lam v. City of San
    Jose, 
    869 F.3d 1077
    , 1084 (9th Cir. 2017) (citation omitted).
    We review the voluntariness of a confession de novo and any
    underlying factual findings for clear error. United States v.
    Heller, 
    551 F.3d 1108
    , 1112 (9th Cir. 2009).
    B. The District Court Did Not Abuse its Discretion
    by Wholly Adopting the Magistrate Judge’s
    Report and Recommendation
    Under the Federal Magistrates Act, a district court may
    designate a magistrate judge to conduct an evidentiary
    hearing and submit proposed findings of fact and
    recommendations for the disposition of a motion to suppress.
    
    28 U.S.C. § 636
    (b)(1)(B). Within fourteen days, any party
    may file written objections to the report. 
    Id.
     § 636(b)(1)(C).
    If an objection is made, the district court “shall make a de
    novo determination of those portions of the report or
    specified proposed findings or recommendations to which
    objection is made.” Id.; see also Fed. R. Civ. P. 72(b)(3);
    United States v. Reyna-Tapia, 
    328 F.3d 1114
    , 1121 (9th Cir.
    UNITED STATES V. RAMOS                  15
    2003) (“[T]he district judge must review the magistrate
    judge’s findings and recommendations de novo if objection
    is made, but not otherwise.”). After conducting de novo
    review, the district court “may accept, reject, or modify, in
    whole or in part, the findings or recommendations made by
    the magistrate judge.” 
    28 U.S.C. § 636
    (b)(1)(C). “In
    providing for a de novo determination . . . Congress
    intended to permit whatever reliance a district judge, in the
    exercise of sound judicial discretion, chose to place on a
    magistrate’s proposed findings and recommendations.”
    United States v. Raddatz, 
    447 U.S. 667
    , 676 (1980) (internal
    quotation marks omitted).
    Under this statutory scheme, the district court did what
    § 636(b) requires: it indicated that it reviewed the record de
    novo, found no merit to Ramos’s objections, and summarily
    adopted the magistrate judge’s analysis in his report and
    recommendation. We have presumed that district courts
    conduct proper de novo review where they state they have
    done so, even if the order fails to specifically address a
    party’s objections. See Wang v. Masaitis, 
    416 F.3d 992
    ,
    1000 (9th Cir. 2005) (holding that “[t]here [was] no reason
    to question the de novo review done by” the district court
    based on an order stating it “reviewed the Petition and other
    papers along with the attached Report and Recommendation
    . . . as well as petitioner’s objections and respondent’s
    response to petitioner’s objections, and has made a de novo
    determination”); Holder v. Holder, 
    392 F.3d 1009
    , 1022 (9th
    Cir. 2004) (“The district court expressly stated in its order
    that it adopted the magistrate judge’s recommendations only
    after having undertaken a de novo review of the record . . . .
    The district court’s approach fully complied with the
    statutory requirements in using the magistrate judge’s
    assistance in this case.”); N. Am. Watch Corp. v. Princess
    16                      UNITED STATES V. RAMOS
    Ermine Jewels, 
    786 F.2d 1447
    , 1450 (9th Cir. 1986) (holding
    that the district court satisfied de novo review because it
    provided a statement that it had reviewed the record and
    magistrate judge’s report and recommendation before
    reaching its conclusion). 3
    3
    We have also upheld similar district court orders in unpublished cases.
    See, e.g., United States v. Drapel, 
    418 F. App’x 630
    , 630-31 (9th Cir.
    2011); Brook v. McCormley, 
    837 F. App’x 433
    , 435-36 (9th Cir. 2020);
    Payne v. Marsteiner, No. 21-55296, 
    2022 WL 256357
    , at *1 (9th Cir.
    Jan. 26, 2022).
    Additionally, our sister circuits have upheld district court orders that
    adopt the magistrate judge’s report and recommendation without
    additional analysis of case-specific facts or law. See, e.g., Elmendorf

    UNITED STATES V. RAMOS                  17
    Only in limited circumstances have we questioned a
    district court’s de novo review of a magistrate judge’s report
    and recommendation. For example, we have reversed and
    remanded district court orders adopting the magistrate
    judge’s recommendation because it was clear that the district
    court failed to conduct review on the whole record. See
    United States v. Remsing, 
    874 F.2d 614
    , 616-18 (9th Cir.
    1989) (reversing and remanding because the transcript of the
    evidentiary hearing was unavailable when the district court
    conducted its review); Orand v. United States, 
    602 F.2d 207
    ,
    209 (9th Cir. 1979) (reversing and remanding because, in
    part, the “stenographic notes from the magistrate’s hearing
    were not fully transcribed until . . . three months after the
    district court adopted the magistrate’s report and
    recommendation”). We have also vacated and remanded the
    district court’s order where it clearly applied the wrong
    standard of review. See CPC Pat. Techs. Pty Ltd. v. Apple,
    Inc., 
    34 F.4th 801
    , 810 (9th Cir. 2022) (vacating and
    remanding a district court order because it expressly
    reviewed the magistrate judge’s decision for clear error
    rather than de novo).
    Ramos argues that this is one of those limited
    circumstances where we should question the district court’s
    repeated assertions that it conducted de novo review.
    According to Ramos, the district court’s “bare assertion” that
    it reviewed de novo is insufficient because the order was
    “mere boilerplate” and failed to address his specific
    objections. But the district court asserted that it conducted
    de novo review not only in its order adopting the magistrate
    judge’s report and recommendation, but also in its order
    denying the motion for reconsideration.
    More importantly, as discussed above, the district court
    had no obligation to provide individualized analysis of each
    18                  UNITED STATES V. RAMOS
    objection. See Wang, 
    416 F.3d at 1000
     (affirming a cursory
    district court order summarily adopting, without addressing
    any objections, a magistrate judge’s report and
    recommendation); Holder, 
    392 F.3d at 1022
     (holding that
    the district court’s approach “fully complied with the
    statutory requirements” because it “expressly stated in its
    order that it adopted the magistrate judge's recommendations
    only after having undertaken a de novo review of the record,
    the Second Report and Recommendation, Jeremiah's
    objections, and Carla's responses”); N. Am. Watch Corp.,
    786 F.2d at 1450 (holding that the district court “satisfied the
    de novo standard of 
    28 U.S.C. § 636
    ” by noting it had
    “reviewed the complaint, counter-complaints, all the records
    and files, . . . and the . . . Report and Recommendation of the
    United States Magistrate”).
    The cases on which Ramos relies for this point are
    inapposite. Two of the three cited cases involved new claims
    raised for the first time in a party’s objections to the
    magistrate judge’s report and recommendation. See Brown,
    
    279 F.3d at 745
     (holding that the district court abused its
    discretion by failing to address the pro se habeas petitioner’s
    equitable tolling argument raised for the first time in his
    objections to the magistrate judge’s report and
    recommendation (citing United States v. Howell, 
    231 F.3d 615
    , 622 (9th Cir. 2000)); United States v. Cha, 
    597 F.3d 995
    , 1003 n.7 (9th Cir. 2010) (holding that the district
    court’s “boilerplate language” was not enough when
    addressing the government’s waiver argument raised for the
    first time in its objections).        By contrast, Ramos’s
    objection—that the magistrate judge erred in finding that he
    was not threatened with the baggie and drug charges—is a
    UNITED STATES V. RAMOS                         19
    reformulation of his argument from his motion to suppress. 4
    The third (unpublished) case Ramos cites is also
    distinguishable because, there, the magistrate judge failed to
    address one of the defendant’s arguments in his report and
    recommendation. United States v. Jones, 
    837 F. App’x 423
    ,
    424 (9th Cir. 2021). But here, Ramos does not contend that
    the report and recommendation itself failed to address an
    argument raised in his motion to suppress.
    The dissent agrees with Ramos that the district court’s
    order was procedurally deficient and believes that the district
    court failed to conduct de novo review, as evidenced by the
    “rubberstamp” order. Dissent at 33-35. But, like Ramos, the
    dissent cites no caselaw from any court requiring the district
    court to provide more analysis or case-specific reasoning
    when summarily adopting a magistrate judge’s report and
    recommendation, absent newly raised objections. The only
    evidence that the dissent cites is the district court’s nearly
    identical orders in other cases. Dissent at 34-35. The dissent
    finds it of no matter that the district court confirmed not only
    once (in its order adopting the magistrate judge’s report and
    recommendation) but twice (in its order denying Ramos’s
    motion for reconsideration) that it conducted de novo review
    of the case. When the district court said it independently
    reviewed the record and there is no evidence indicating
    4
    Ramos raised an additional objection, arguing that the magistrate judge
    made an improper inference about the contents of the plastic baggie,
    thereby relieving the government of its burden of proof. But, as we
    explain below, the magistrate judge did no such thing. The magistrate
    judge noted that the government did not explain the bag but listed the
    many factors on which the government relied to prove the confession
    was voluntary by a preponderance of the evidence.
    20                      UNITED STATES V. RAMOS
    otherwise, we have no reason to second-guess its assertion
    of de novo review. 5 See Wang, 
    416 F.3d at 1000
    .
    C. The District Court Did Not Err in Denying
    Ramos’s Motion to Suppress on Voluntariness
    Grounds
    Turning to the merits, Ramos contends that the district
    court erred in denying his motion to suppress because it
    mistakenly adopted the magistrate judge’s “improper
    speculation regarding the contents of the baggie shown to
    Mr. Ramos when he was detained.” We disagree and affirm
    the district court’s denial of Ramos’s motion to suppress his
    post-arrest statements and the underlying analysis in the
    magistrate judge’s report and recommendation.
    The magistrate judge did not, nor was he required to,
    make a proposed finding about the contents of the baggie;
    rather, he only had to consider whether Ramos’s “will was
    overborne” under the totality of the circumstances. United
    States v. Leon Guerrero, 
    847 F.2d 1363
    , 1366 (9th Cir.
    1988); see also Lego v. Twomey, 
    404 U.S. 477
    , 489 (1972)
    (“[T]he prosecution must prove at least by a preponderance
    of the evidence that the confession was voluntary.”). After
    observing the implausibility of Ramos’s testimony and
    5
    Ramos’s motion for reconsideration argued that the district court failed
    to conduct de novo review because the order adopting the report and
    recommendation stated that “as to any new . . . arguments . . . not timely
    . . . raised before [the magistrate judge], the Court exercises its discretion
    to not consider those matters and considers them waived” even though,
    according to Ramos, the case raised no waiver issue. But this argument
    misses the point. The fact that the order contained extraneous language
    does not negate the district court’s multiple assertions that it conducted
    de novo review and the magistrate judge’s proper analysis in
    recommending denial of the motion to suppress.
    UNITED STATES V. RAMOS                 21
    considering Ramos’s verbal and signed Miranda waiver,
    age, education level, and fluency in English, the magistrate
    judge properly recommended finding the statements made
    during the interrogation voluntary.
    Moreover, we cannot hold that the magistrate judge was
    wrong to reject Ramos’s testimony. See United States v.
    Nelson, 
    137 F.3d 1094
    , 1110 (9th Cir. 1998) (“This court
    gives special deference to the district court’s credibility
    determinations.”). The magistrate judge’s report and
    recommendation provided ample reason to find Ramos not
    credible: (1) Ramos contradicted himself throughout his
    testimony, such as claiming that he was taking the
    passengers to Phoenix but later testifying that their
    destination was Tucson; (2) he told an “untenable story”
    where he was offered $1,000 to take the passengers
    “Christmas shopping,” even though he did not have his
    driver’s license and was wearing scrubs on the night of his
    arrest; (3) he offered claims that were inconsistent with his
    repeated requests during the interrogation asking what the
    “agents could do for him”; and (4) the magistrate judge
    observed that, during his testimony, Ramos’s “demeanor
    was . . . that of a fabricator.” Ramos’s testimony bore many
    of the hallmarks of an unreliable witness. See generally
    Ninth Circuit Manual of Model Criminal Jury Instructions §
    1.7 (2022) (“In considering the testimony of any witness,
    you may take into account . . . the witness’s manner while
    testifying,” “the witness’s interest in the outcome of the
    case,” “whether other evidence contradicted the witness’s
    testimony,” and “the reasonableness of the witness’s
    testimony in light of all the evidence[.]”).
    The rest of the record also supports the magistrate
    judge’s analysis. The video footage—the only other piece
    of evidence that Ramos cites to support his claim—only
    22                 UNITED STATES V. RAMOS
    confirms that Agent Marrufo had a baggie in his hand when
    talking to Ramos. But this footage is without audio and does
    not clearly show the contents of the baggie. And, in contrast
    to Ramos’s account, Agents Marrufo and Barron denied ever
    threatening Ramos. Further, despite extensive back and
    forth between Ramos and the agents, the transcript of the
    interrogation that immediately followed Agent Marrufo’s
    visit makes no mention of the plastic baggie or purported
    drug charges. Because there are “two permissible views of
    the evidence,” the magistrate judge’s choice between them,
    with which the district court agreed, cannot be clearly
    erroneous. Anderson v. Bessemer City, 
    470 U.S. 564
    , 574
    (1985). And without his claim that he was threatened,
    Ramos’s “argument that his confession was coerced is
    meritless.” United States v. Wolf, 
    813 F.2d 970
    , 975 (9th
    Cir. 1987).
    The dissent argues that the district court’s order denying
    the suppression motion was inadequate on the merits
    because it relied on a clearly erroneous proposed finding of
    fact in the magistrate judge’s report and recommendation:
    “that the ‘most likely’ reason why Marrufo had the baggie
    was that it contained the medicine that Ramos had
    requested.” Dissent at 31. According to the dissent, this
    finding was clearly erroneous because Agent Marrufo never
    actually gave the baggie to Ramos and Agent Regan testified
    that he was the one who gave Ramos his medication. Dissent
    at 31. But this mischaracterizes the magistrate judge’s
    report, which accurately stated that the government failed to
    explain the bag but noted there were “alternative
    explanations,” speculating “[t]he most likely of which is that
    the bag contained medicine Defendant had requested.”
    Furthermore, as discussed above, the magistrate judge was
    not required to propose a factual finding about the contents
    UNITED STATES V. RAMOS                  23
    of the bag. The question before the magistrate judge was
    whether Ramos’s confession was voluntary, which the
    magistrate judge addressed after considering the totality of
    the circumstances and rejecting Ramos’s testimony from the
    motion to suppress hearing—the only evidence supporting
    the allegation of fabricated drug charges.
    The dissent’s selective focus on the plastic baggie thus
    ignores the actual question that was before the magistrate
    judge and district court: whether the confession was
    voluntary. Critical to that question was whether Ramos was
    credible. By ignoring the magistrate judge’s detailed
    analysis finding Ramos not credible, the dissent improperly
    discounts the standard of review, which is especially
    important in this context: “Deference to the district court’s
    factual finding is especially warranted here when the critical
    evidence is testimonial; the ‘judge was in the unique position
    to observe the demeanor of both [the defendant] and the
    police officers while we have only the cold record, which is
    sterile by comparison.’” Wolf, 
    813 F.2d at 975
     (quoting
    United States v. Hood, 
    493 F.2d 677
    , 680 (9th Cir. 1974)).
    D. Conclusion
    Because the district court was not obligated to explicitly
    address Ramos’s objections, we hold that the district court
    did not abuse its discretion by adopting the magistrate
    judge’s report and recommendation. On the merits, we also
    affirm the district court’s denial of the suppression motion
    on voluntariness grounds.
    AFFIRMED.
    24                 UNITED STATES V. RAMOS
    COLLINS, Circuit Judge, concurring in the judgment in part
    and dissenting in part:
    I concur in the court’s accompanying unpublished
    memorandum disposition, which holds that (1) the district
    court properly denied Defendant Demetrius Verardi
    Ramos’s motion to suppress insofar as it was directed at the
    statements that he made prior to his arrest; and (2) the case
    must be remanded so that the written judgment’s description
    of supervised release conditions can be properly conformed
    to the orally pronounced sentence. But I respectfully dissent
    from the majority’s conclusion that the district court
    properly denied the motion to suppress insofar as it was
    directed at Ramos’s confession in jail after his arrest. As to
    that issue, I would instead remand with instructions to re-
    examine the matter and, if warranted, to grant Ramos a new
    trial.
    I
    After Ramos was arrested, he was taken to a Border
    Patrol Station where agents placed him into a holding cell.
    The cell contained a video camera that recorded events
    within the cell, but without any audio. The video recording
    shows that, at approximately 3:41 AM, Agent Robert
    Marrufo visited Ramos’s cell and spoke with him for about
    two minutes before leaving. The recording further shows
    that, at approximately 4:23 AM, Marrufo returned to
    Ramos’s cell. This time, Marrufo spoke with Ramos for
    approximately 40 seconds, and for about half of that
    conversation, Marrufo was prominently holding out towards
    Ramos a clear plastic baggie that contained some substance
    at the bottom. Although the video is grainy, the plastic
    baggie contained at the top what appears to be a pinkish strip
    that is consistent with a Ziploc-type strip. Towards the end
    UNITED STATES V. RAMOS                       25
    of the conversation, Marrufo gestured with his right arm in a
    way that seemingly indicated that Ramos should follow him.
    At approximately the same time, Ramos moved to grab his
    shoes, put them on, and left the cell after Marrufo. Ramos
    proceeded to an interview room, where he waived his
    Miranda rights and gave a recorded confession.
    Both Ramos and Marrufo testified at the suppression
    hearing about the content of these two conversations, and
    Marrufo also testified about them at trial. Marrufo was not
    shown the video recording at the suppression hearing, but he
    was shown it at trial. As to Marrufo’s first visit, Ramos
    testified that Marrufo told him that if he did not cooperate
    with the agents, “it’s going to be very bad for you,” but that
    if Ramos cooperated, then he would be released that night.1
    Marrufo testified that he first visited Ramos to “check up on
    him,” given that Ramos had been very distraught at the time
    of his arrest. Marrufo stated that, during this initial visit, he
    also told Ramos that they knew that he was a Brazilian who
    was unlawfully in the U.S. and that it would be helpful for
    Ramos to tell the truth. Marrufo specifically denied that he
    said anything about Ramos being released that night, and he
    denied making any promises to Ramos.
    As to the second visit, Ramos testified that Marrufo said
    that the baggie contained drugs that had been found in
    Ramos’s car and that, if he did not cooperate, he would be
    charged with drug trafficking and “[t]hat’s going to give you
    1
    In response to a leading question from his own counsel, Ramos
    mistakenly agreed that the agent who visited him was “Agent Barron”
    (who had also been involved in Ramos’s arrest) rather than Agent
    Marrufo. All parties agree that the agent in the video is Marrufo. The
    magistrate judge did not rely on this error in explaining why he found
    Ramos not to be credible.
    26                 UNITED STATES V. RAMOS
    years in prison.” Ramos said that Marrufo reiterated that, “if
    you talk to us you can go home tonight.” According to
    Ramos, Marrufo asked him to agree to an interview right
    away, saying, “Come over here with us.” At the suppression
    hearing, Marrufo testified that he did not remember whether
    he had brought a baggie with him to Ramos’s cell, but he
    affirmatively denied telling Ramos that drugs had been
    found in his vehicle, and he denied threatening him with
    drug charges.        In cross-examining Marrufo at the
    suppression hearing, the prosecutor elicited an affirmative
    response to a question about whether, as part of a “welfare
    check,” Marrufo sometimes brought food in baggies. In
    redirect examination, defense counsel asked point blank
    whether Marrufo had given Ramos food in his cell, and
    Marrufo said, “I didn’t give him any food.” Defense counsel
    then asked, “So if you didn’t ever give him food, why would
    you have a baggie in your hand?” Marrufo responded, “I
    don’t recall if I had a baggie in my hand or not.”
    At trial, Marrufo was again asked about the second visit,
    and—before he had seen the video recording of the second
    visit—he testified that “I didn’t show him a baggie. If I had
    one in my hand, then I had it in my hand because I was doing
    something else with it, but it wasn’t to show him a baggie.”
    Marrufo again denied threatening Ramos with drug charges,
    stating, “He didn’t have any drugs in his possession, why
    would I charge him with drugs?” After being shown the
    recording, Marrufo said that the baggie “looks like an
    evidence bag,” and he noted that Ramos’s cell was “en route
    to the evidence locker.”
    Ramos moved to suppress his confession on the ground,
    inter alia, that it was involuntarily given in response to the
    threat that he would be falsely charged with a drug crime.
    The evidentiary hearing on the motion to suppress was held
    UNITED STATES V. RAMOS                   27
    before a magistrate judge, who prepared a report under 
    28 U.S.C. § 636
     recommending that the motion be denied. The
    magistrate judge gave numerous reasons for finding Ramos
    not to be credible, including that many aspects of his overall
    testimony and statements were “not plausible” and that “his
    demeanor was not that of an honest but nervous witness, but
    instead was that of a fabricator.” As to the conflicting
    testimony about a baggie, the magistrate stated: “The
    Government does not explain the bag, but there are
    alternative explanations. The most likely of which is that the
    bag contained medicine Defendant had requested.” This
    comment was apparently a reference to the fact that Agent
    Daniel Regan had testified at the suppression hearing that, at
    one point, Ramos requested prescription medication that was
    in his car at the time of his arrest, and Regan retrieved it for
    him.
    Ramos filed timely objections to the magistrate’s report.
    On the voluntariness issue, Ramos’s objection emphasized
    the “PLASTIC BAGGIE,” which he referenced in all capital
    letters. After noting that the magistrate judge conceded that
    “the government could not explain the bag,” Ramos argued
    that the magistrate judge engaged in an “extraordinary act of
    speculation” by positing an explanation that the Government
    itself had not offered, namely that “the bag likely contained
    medicine that the Defendant had requested.” Ramos argued
    that a “viewing of the video of the bag does not support it
    containing medicine or pill bottles or anything but powder
    on the bottom of the bag.” Ramos further argued:
    The video shows Border patrol Agent
    Mar[r]ufo showing Mr. Ramos a bag
    containing some sort of powder on the
    bottom of the bag.     Agent Mar[r]ufo
    28                 UNITED STATES V. RAMOS
    conveniently has no recollection. For some
    reason, the Magistrate Judge goes out of his
    way to present a reason for the baggie that is
    not supported in the evidence.
    In a boilerplate order, the district court overruled the
    objections and adopted the magistrate judge’s report. Ramos
    moved for reconsideration, complaining that the district
    court’s order was bereft of any discussion of the facts or the
    issues of Ramos’s motion and that, in his view, the district
    judge had failed to conduct the de novo review required by
    the statute. The district court denied the motion. Well more
    than half of the text of that order consists of verbatim
    quotations from the prior order adopting the magistrate’s
    report. The remainder consists of conclusory assertions that
    the district judge reviewed everything and conducted a de
    novo review. The relevant text of the order denying
    reconsideration—like the prior order adopting the magistrate
    judge’s report—contains no mention whatsoever of any of
    the case-specific facts or legal issues raised by Ramos’s
    motion or by his objections to the magistrate judge’s report.
    II
    In my view, the district judge’s failure to discuss any of
    the issues raised by Ramos’s motion to suppress or by
    Ramos’s objections to the magistrate judge’s report is
    unacceptable and warrants remand.
    In defining what types of pretrial motions a magistrate
    judge is empowered to resolve in the first instance, the
    relevant statute specifically excludes a motion “to suppress
    evidence in a criminal case.” 
    28 U.S.C. § 636
    (b)(1)(A).
    Instead, with respect to a defense motion to suppress, a
    magistrate judge is only authorized, if designated by the
    UNITED STATES V. RAMOS                   29
    district judge, “to conduct hearings, including evidentiary
    hearings, and to submit to a judge of the court proposed
    findings of fact and recommendations for the disposition, by
    a judge of the court,” of that motion. 
    Id.
     § 636(b)(1)(B). The
    statute further provides that “[w]ithin fourteen days after
    being served with a copy” of the magistrate judge’s report,
    “any party may serve and file written objections to such
    proposed findings and recommendations as provided by
    rules of court.” Id. § 636(b)(1). If such objections are timely
    filed, then a district “judge of the court shall make a de novo
    determination of those portions of the report or specified
    proposed findings or recommendations to which objection is
    made.” Id. (emphasis added); see also FED. R. CIV. P.
    72(b)(3).
    We have held that, in some cases, a district judge may
    satisfy the required statutory de novo review by including,
    in the order ruling on the parties’ objections, an unadorned
    statement that he or she has adopted the magistrate judge’s
    report after fully considering the record, the report, and the
    parties’ objections to the report. See, e.g., North Am. Watch
    Corp. v. Princess Ermine Jewels, 
    786 F.2d 1447
    , 1450 (9th
    Cir. 1986). But “[b]ecause there is a concern that a district
    judge may nevertheless be tempted on occasion to rubber
    stamp the recommendation of a magistrate, the courts of
    appeal[s] have responsibility to ensure that the district judge
    has taken the task of de novo review seriously.” See 12 C.A.
    WRIGHT, A. MILLER, & R. MARCUS, FEDERAL PRACTICE AND
    PROCEDURE § 3070.2, p. 453 (3d ed. 2014).                  That
    responsibility is all the more important when, as here, the
    district judge’s conclusory statement that a de novo review
    was conducted is unaccompanied by any case-specific
    reasoning whatsoever. Cf. United States v. Jones, 
    22 F.4th 667
    , 679 (7th Cir. 2022) (upholding district judge’s adoption
    30                     UNITED STATES V. RAMOS
    of magistrate judge’s report in a brief order that did contain
    case-specific discussion of objections (referencing United
    States v. Jones, 
    2020 WL 2507927
     (N.D. Ind. May 15,
    2020)). Thus, while we should “normally presume that the
    district court has made such a de novo review,” that
    presumption should not apply if “affirmative evidence
    indicates otherwise.” United States v. Romano, 
    794 F.3d 317
    , 340 (2d Cir. 2015) (simplified); see also Gonzalez-
    Perez v. Harper, 
    241 F.3d 633
    , 636 (8th Cir. 2001) (stating
    that the court will presume that the district judge conducted
    a proper de novo review “absent evidence to the contrary”).
    For several reasons, such a presumption is not warranted
    here. 2
    First, the magistrate judge’s report contains an obvious
    factual error concerning a critical issue and the error was
    raised in Ramos’s objections. Cf. Murphy v. IBM Corp., 
    23 F.3d 719
    , 722 (2d Cir. 1994) (noting that the “correctness of
    the report” in that case was a factor that confirmed the
    propriety of summarily adopting it). Ramos’s motion to
    suppress his confession based on voluntariness rested
    dispositively on his claim that, during his second visit to
    Ramos’s cell, Marrufo had confronted Ramos with a baggie
    of drugs that Marrufo (falsely) claimed were found in
    Ramos’s car and that, if Ramos did not cooperate, Ramos
    2
    I reject the majority’s suggestion that the relevant inquiry is whether
    there are grounds “to second-guess” the veracity of the district court’s
    “assertion” that it has conducted a de novo review. See Opin. at 19–20.
    I have no reason to doubt that the district judge endeavored to address
    the merits of Ramos’s motion conscientiously and that, subjectively, the
    judge believed that he had conducted a sufficient de novo review. But
    our subjective beliefs are not always objectively accurate and, when
    measured up against objective standards, the judge’s order here falls
    short.
    UNITED STATES V. RAMOS                    31
    would be sent to prison for years on a drug trafficking
    charge. Marrufo flatly denied that he had said any such
    thing. Ramos’s claim on this score simply cannot adequately
    be assessed without a sufficient factual finding as to what
    Marrufo did or did not say during that second cell visit. On
    this point, there were aspects to both men’s testimony that
    were problematic. As the magistrate judge noted, Ramos’s
    credibility was generally impaired by the implausibility of
    some of his other testimony and statements, and that general
    lack of credibility could suffice to reject his testimony on this
    score as well. On the other hand, as the magistrate judge
    noted, the Government had failed to explain the baggie.
    Marrufo could not explain it either, because he stated at the
    suppression hearing that he did not recall whether he had a
    baggie. In nonetheless finding that Marrufo did not threaten
    Ramos with a baggie of drugs, the magistrate judge
    speculated that the “most likely” reason why Marrufo had
    the baggie was that it contained the medicine that Ramos had
    requested. But that speculation is clearly erroneous, because
    (1) the recording shows that Marrufo did not give the baggie
    or its contents to Ramos during the cell visit; and (2) the
    hearing testimony established that a different agent was the
    one who gave Ramos his medication.
    On appeal, the Government points to the different
    explanation that Marrufo gave at trial, when he stated that
    the baggie was probably an evidence bag that he happened
    to be carrying with him on his way to the evidence locker.
    See Rocha v. United States, 
    387 F.2d 1019
    , 1021 (9th Cir.
    1967) (“In determining whether a district court erred in
    admitting evidence claimed to have been seized as the result
    of an unreasonable search, an appellate court will not
    ordinarily limit itself to the testimony received at a pretrial
    motion to suppress, but will also consider pertinent
    32                  UNITED STATES V. RAMOS
    testimony given at the trial.”). But this explanation is hard
    to square with the video recording, in which Marrufo
    prominently extends his arm and holds out the bag towards
    Ramos for nearly half of the visit. Even though there is no
    audio, the inference appears inescapable that Marrufo is
    discussing the baggie with Ramos. Indeed, it is notable that
    both of the explanations raised at the suppression hearing
    (i.e., the Government’s suggestion in cross-examination that
    Marrufo was bringing Ramos food and the magistrate
    judge’s suggestion that Marrufo was bringing him medicine)
    rest on the view that Marrufo was discussing the baggie with
    Ramos.
    As I noted earlier, Ramos’s objections to the magistrate
    judge’s report prominently highlighted this key issue about
    why Marrufo was showing Ramos a baggie that appears to
    contain a powdery substance, and it specifically (and
    correctly) pointed out that the magistrate judge’s medicine
    explanation was rank speculation that was unsupported by
    the record. Given this backdrop, it is very difficult to see
    how the requisite de novo review of this objection, and of
    the magistrate judge’s report, could have led to a wholesale
    adoption of that report without any modification whatsoever.
    Even if the district judge thought that the magistrate judge
    reached the right ultimate conclusion for the wrong reasons,
    the district court would still be obligated either to correct the
    report before adopting it or to adopt it only in part. See 
    28 U.S.C. § 636
    (b)(1) (requiring a de novo “determination” of
    any “specified proposed findings . . . to which objection is
    made”).
    The majority dismisses this erroneous statement by the
    magistrate judge on the grounds that it was immaterial to the
    overall correctness of the report. See Opin. at 22–23.
    According to the majority, the error does not matter because
    UNITED STATES V. RAMOS                   33
    the magistrate judge “was not required to propose a factual
    finding about the contents of the bag,” but only had to decide
    “whether Ramos’s confession was voluntary.” Opin. at 22–
    23; see also Opin. at 20. This comment fundamentally
    misconceives the role of a district judge in reviewing a
    magistrate judge’s report and recommendation under
    § 636(b)(1)(B). That role is not akin to this court’s review
    of district court judgments, which may be affirmed, despite
    clear errors, so long as those mistakes are harmless. See
    generally Neder v. United States, 
    527 U.S. 1
    , 8–9 (1999)
    (discussing scope of harmless-error review of constitutional
    errors); United States v. Berry, 
    627 F.2d 193
    , 201 (9th Cir.
    1980) (stating that, if there was a “non-constitutional error,”
    we may “affirm if the error is more probably harmless than
    not”). Because, for the narrow class of motions governed by
    § 636(b)(1)(B), the magistrate judge may only submit
    “proposed findings of fact and recommendations for the
    disposition” of the motion, see 
    28 U.S.C. § 636
    (b)(1)(B)
    (emphasis added), any such report—including the errors
    within it—becomes the ruling of the district court itself to
    the extent that it is adopted. In that sense, a magistrate
    judge’s report under § 636(b)(1)(B) is more akin to a draft
    opinion than to a judgment. Accordingly, where, as here, the
    magistrate judge’s report contains a clear error, and the error
    has been correctly called to the district court’s attention by a
    timely objection, the district court abuses its discretion in
    proceeding nonetheless to formally adopt the error as its
    own. And the fact that the district court did so here is a
    strong indication that it did not perform the “proper de novo
    review” required by § 636(b)(1). See Opin. at 15 (emphasis
    added).
    Second, there are good reasons to suspect that the district
    judge’s order adopting the magistrate judge’s report here is,
    34                    UNITED STATES V. RAMOS
    for all practical purposes, a 4½-page rubberstamp. Nearly
    all of the verbiage in the order is non-specific to this case
    and consists largely of citations addressing the legal
    framework for reviewing magistrate judges’ reports. Indeed,
    nearly two full pages consist of a string citation of cases
    upholding, as sufficient to satisfy de novo review, district
    judges’ unexplained orders summarily rejecting objections
    and adopting such reports. The only aspects that relate
    specifically to this case are the names of the magistrate judge
    who filed the report and of the party who objected and the
    docket numbers of the parties’ filings. Moreover, a Westlaw
    search reveals that, on at least 30 other occasions since
    March 2021, this same district judge has entered largely
    verbatim identical boilerplate orders—complete with the
    exact same pages of string cites—rejecting objections to, and
    adopting, magistrate judges’ reports. 3 Indeed, a Westlaw

    in ruling on objections to a magistrate judge’s report. See

    (D. Ariz. June 23, 2022) (summarily rejecting objections and
    adopting magistrate judge’s report recommending transfer
    of case to Phoenix division of the district court). I am
    unaware of any circuit precedent that has ever upheld this
    sort of near-uniform use of unexplained orders that
    summarily adopt magistrate judges’ reports wholesale. Cf.
    Jones, 22 F.4th at 679 (noting that “in some cases, a district
    court may even adopt the magistrate judge’s proposed
    findings and recommendation in its entirety without writing

    36                 UNITED STATES V. RAMOS
    magistrate judges’ reports, but to no avail. In United States
    v. Jones, 
    837 F. App’x 423
     (9th Cir. 2021), the district judge
    adopted the magistrate judge’s report recommending denial
    of a motion to suppress in a one-page summary order that
    was devoid of any reasoning beyond an assertion that the
    “objected-to portions” of the report had been reviewed de
    novo. See United States v. Jones, 
    2018 WL 6329455
    , at *1
    n.1 (D. Ariz. Dec. 4, 2018). In our February 24, 2021
    memorandum affirming that decision, we nonetheless noted:
    [T]he district court should not have
    summarily adopted the magistrate judge’s
    report and recommendation without
    addressing all of Defendant’s objections,
    namely that the magistrate judge failed to
    address his constitutional challenges to [the
    detaining federal agent’s] cross-certification
    [under Arizona law]. See Brown v. Roe, 
    279 F.3d 742
    , 745 (9th Cir. 2002). When a party
    objects to the proposed findings and
    recommendations, the district court judge
    must “make a de novo determination of those
    portions of the report or specified proposed
    findings and recommendations to which
    objection is made.” 
    28 U.S.C. § 636
    (b)(1).
    However, in the case before us, addressing
    the objections would not have resulted in a
    different outcome.
    Jones, 837 F. App’x at 424 (emphasis added). Less than two
    weeks later, on March 9, 2021, the district judge first issued
    what is now his 4½-page standard order overruling
    objections to, and adopting, magistrate judges’ reports. See
    supra note 3. Thus, the district judge’s apparent response to
    UNITED STATES V. RAMOS                    37
    our admonition in Jones about summarily adopting reports
    was to craft a new standard order explicitly defending and
    continuing a consistent practice of such summary adoptions.
    As Ramos noted below, the boilerplate nature of the
    district judge’s order in this case is starkly illustrated by the
    fact that the order begins with a wholly inapposite paragraph
    discussing the court’s decision to “exercise[] its discretion to
    not consider” any “new evidence, arguments, and issues that
    were not timely and properly raised” before the magistrate
    judge and to instead deem those points to be “waived.” This
    paragraph makes no sense, because there were no such
    “waived” matters in Ramos’s objections, and the
    Government’s response to those objections did not argue that
    any of them had been waived. By holding that even this
    peculiar inclusion of inapplicable boilerplate makes no
    difference here, see Opin. at 20 n.5, the majority underscores
    its wholesale abdication of any meaningful review in this
    area. Under today’s opinion, every district judge in the
    circuit will now be incentivized to develop a similar, one-
    size-fits-all rubberstamp order.
    Fourth, it is important to keep in mind that the underlying
    issue here is one of constitutional dimension. In holding that
    “the Constitution [is] not violated by the reference to a
    Magistrate [Judge] of a motion to suppress evidence in a
    felony trial,” the Supreme Court has emphasized that the
    statutory requirement of de novo review ensures that “the
    handling of suppression motions invariably remains
    completely in the control of the federal district court.”
    Peretz v. United States, 
    501 U.S. 923
    , 937–38 (1991)
    (quoting United States v. Raddatz, 
    447 U.S. 667
    , 685 (1980)
    (Blackmun, J., concurring)). Where, as here, there are
    reasons to believe that the requisite review and control by
    the district judge may not have occurred, principles of
    38                  UNITED STATES V. RAMOS
    avoidance of constitutional concerns provide a further
    ground for a remand and re-examination.
    Finally, I do not think that we can say that the district
    court’s error was harmless. As I have explained, the problem
    here is that the magistrate’s report contains a clearly
    erroneous finding about why Marrufo had the baggie, and
    this court, as an appellate tribunal, lacks any authority to say
    what factual finding should replace that defective
    determination. The evidence on the point was hotly
    disputed, there are difficulties with both side’s explanations,
    and the record would support more than one resolution. Nor,
    on this record, do I think that we can say that, regardless of
    the competing explanations for the baggie, Ramos is
    somehow not credible on this point as a matter of law. The
    only person who ultimately can make this determination is
    not us, nor is it the magistrate judge—only the district judge
    can resolve this point by making appropriate factual
    determinations that are untainted by the magistrate judge’s
    clear error.
    Accordingly, I think that there are sufficient grounds to
    warrant remand here with instructions to issue a new order
    that reflects the requisite de novo review and that does not
    summarily adopt a magistrate judge’s report that contains a
    clearly erroneous factual finding on a critical issue.
    *       *       *
    For the foregoing reasons, I would remand this matter to
    the district court with instructions that the district judge
    reconsider the suppression motion de novo and, if that
    motion is found to have merit, to then order a new trial. To
    the extent that the majority concludes otherwise, I
    respectfully dissent.
