    In December of 2019, Mr. Steven Anderson was stopped by police after a woman
    complained he was harassing her and an officer observed him walking in the street in
    violation of a city ordinance. Mr. Anderson provided the officers with false identifying
    Appellate Case: 21-2151     Document: 010110825909          Date Filed: 03/14/2023     Page: 2
    information and was arrested for concealing his identity. During a search incident to
    arrest, law enforcement found a firearm and a crystal-like substance determined to be
    methamphetamine on his person. Following a failed motion to suppress, Mr. Anderson
    pled guilty to being a felon in possession. At sentencing, the district court applied a four-
    level enhancement under U.S.S.G. § 2K2.1(b)(6)(B) for possessing a firearm in
    connection with another felony offense and sentenced Mr. Anderson to fifty-one months
    in prison.
    On appeal, Mr. Anderson challenges the denial of his motion to suppress, arguing
    that law enforcement lacked reasonable suspicion to stop him and that the firearm was
    discovered in violation of his Fourth Amendment rights. He also argues the district court
    erroneously applied § 2K2.1(b)(6)(B), primarily because it relied on an uncorroborated
    police report not admitted into evidence. We hold that law enforcement had reasonable
    suspicion to stop Mr. Anderson and that he failed to show a Fourth Amendment violation
    was the but-for cause of the discovery of the firearm. We also hold that the district court
    did not err in applying the § 2K2.1(b)(6)(B) enhancement. Accordingly, we affirm Mr.
    Anderson’s conviction and sentence.
    Background
    On December 17, 2019, Sergeant Ignas Danius was patrolling a high crime area in
    Albuquerque, New Mexico and was flagged down by a woman pointing toward Mr.
    Anderson. The woman told Sgt. Danius that Mr. Anderson was harassing her. Rec.,
    vol. I at 135. Sgt. Danius began to follow Mr. Anderson, whom he observed walking in
    the street.
    2
    Appellate Case: 21-2151      Document: 010110825909        Date Filed: 03/14/2023      Page: 3
    Sgt. Danius called for backup and approached Mr. Anderson once other officers
    arrived. Sgt. Danius asked Mr. Anderson whether he had identification, to which Mr.
    Anderson said no. Id. at 137. Sgt. Danius then asked Mr. Anderson if he had any
    weapons on him. Id. Mr. Anderson initially did not respond but upon further questioning
    stated he did not have any weapons. Id. In part because Mr. Anderson appeared
    particularly nervous, raised his hands, and was wearing a bulky jacket, Sgt. Danius
    decided to conduct a pat-down for weapons. Mr. Anderson was noncompliant and was
    therefore handcuffed. Sgt. Danius was eventually able to conduct the pat-down but found
    no weapons.
    In response to further questioning, Mr. Anderson repeatedly provided Sgt. Danius
    with false identifying information, including a false name and a social security number
    belonging to another person. Id. at 138. Sgt. Danius arrested Mr. Anderson for
    concealing his identity. Law enforcement later ran Mr. Anderson’s fingerprints,
    determined his actual identity, and discovered he had two outstanding felony arrest
    warrants. Rec., vol. II at 66.
    During a search incident to arrest, Sgt. Danius found a stolen, loaded handgun in
    Mr. Anderson’s waistband and baggies filled with a crystal-like substance. Id. Sgt.
    Danius later found a similar baggie in Mr. Anderson’s sock. Id. Based on Sgt. Danius’s
    training and experience, he identified the substance in the baggies to be
    methamphetamine. Id. This was confirmed by a field test of the substance from Mr.
    Anderson’s sock, which returned positive for methamphetamine. Id. Mr. Anderson was
    3
    Appellate Case: 21-2151     Document: 010110825909          Date Filed: 03/14/2023     Page: 4
    charged in state court with trafficking methamphetamine, among other crimes. Those
    charges were dismissed when he was indicted in this case for being a felon in possession.
    Mr. Anderson filed a motion to suppress, which the district court denied. He then
    entered a conditional guilty plea reserving his right to appeal the denial of his suppression
    motion. At sentencing, Mr. Anderson objected to the application of a four-level guideline
    enhancement under § 2K2.1(b)(6)(B) for possessing a firearm in connection with another
    felony offense—to wit, trafficking methamphetamine. He argued there was insufficient
    evidence to support the enhancement. The district court denied the objection and
    sentenced Mr. Anderson to fifty-one months’ imprisonment.
    The Motion to Suppress
    In his suppression motion, Mr. Anderson argued that Sgt. Danius improperly
    stopped him under Terry v. Ohio, 
    392 U.S. 1
     (1968), because the officer lacked
    reasonable suspicion that he committed a crime, particularly criminal harassment. He
    argued there was no evidence of a pattern of conduct that would have caused a
    reasonable person substantial emotional distress, as required by the relevant New
    Mexico statute. See 
    N.M. Stat. Ann. § 30
    -3A-2. The district court found that Sgt.
    Danius credibly testified that the woman, who appeared frightened, concerned, and
    shaken up, flagged Sgt. Danius down and pointed toward Mr. Anderson. According to
    Sgt. Danius, the woman then said, “He’s harassing me. He’s not leaving me alone. He’s
    asking me for my number. He’s asking to date him. If I have a boyfriend, and then he
    asked me for money.” Rec., vol. I at 141. Based on this testimony, the court held Sgt.
    Danius reasonably suspected Mr. Anderson of committing harassment.
    4
    Appellate Case: 21-2151      Document: 010110825909           Date Filed: 03/14/2023       Page: 5
    The court also found that “Sgt. Danius credibly testified he observed [Mr.
    Anderson] walking in the street,” 
    id.,
     and held that Sgt. Danius had reasonable suspicion
    to stop him for violating the city ordinance prohibiting walking “along or upon” a
    roadway when a sidewalk is available, see Albuquerque Code Ordinance § 8-2-7-7(A).1
    Mr. Anderson did not contend otherwise.
    Mr. Anderson did argue that Sgt. Danius lacked reasonable suspicion to conduct the
    pat-down frisk, but he did not specifically argue that the frisk resulted in the discovery of
    his firearm. The district court found that Sgt. Danius “reasonably and credibly believed
    that [Mr. Anderson] was abnormally nervous and had his hands raised.” Rec., vol. I
    at 142. It also noted that Mr. Anderson fled from the scene of the alleged harassment, did
    not have identification, did not answer when first asked if he was armed, repeatedly stated
    he did not know why he was being stopped, and was wearing multiple layers of clothing.
    The court held Sgt. Danius had reasonable suspicion to frisk Mr. Anderson for weapons.
    The court further noted that no evidence was found during the pat-down, and held that the
    pat-down was not the but-for cause of the discovery of the firearm. The court therefore
    denied Mr. Anderson’s motion to suppress.
    Standard of Review
    We review the denial of a suppression motion for clear error with respect to
    findings of fact and de novo with respect to the ultimate question of reasonability. United
    1
    Concerning this jaywalking ordinance, Mr. Anderson argued the stop constituted
    selective enforcement in violation of his equal protection rights. The district court
    rejected this argument, and Mr. Anderson does not renew it on appeal.

    States v. Gambino-Zavala, 
    539 F.3d 1221
    , 1225 (10th Cir. 2008). Evidence is viewed “in
    the light most favorable to the government.” 
    Id.
     Suppression arguments are preserved
    through “sufficiently definite, specific, detailed and nonconjectural factual allegations.”
    
    Id.
     at 1227 n.2 (quoting United States v. Barajas-Chavez, 
    358 F.3d 1263
    , 1266 (10th Cir.
    2004)). When a defendant fails to raise a particular suppression argument in district
    court, the argument is waived absent a showing of good cause. See United States v.
    Warwick, 
    928 F.3d 939
    , 944 (10th Cir. 2019); Fed. R. Crim. P. 12(c)(3). Failure to show
    good cause precludes even plain error review. United States v. Bowline, 
    917 F.3d 1227
    ,
    1236–37 (10th Cir. 2019).
    A district court’s application of the sentencing guidelines is reviewed for abuse of
    discretion. United States v. Rodriguez, 
    945 F.3d 1245
    , 1248 (10th Cir. 2019). “In
    applying that standard, we review questions of law de novo and factual findings for clear
    error, ‘giving due deference to the district court’s application of the Guidelines to the
    facts.’”

     (quoting United States v. Pentrack, 
    428 F.3d 986
    , 969 (10th Cir.
    2005)). “In particular, we review the application of § 2K2.1(b)(6)(B) in a given case for
    clear error.” United States v. Leib, 
    57 F.4th 1122
    , 1125–26 (10th Cir. 2023). We also
    review “a district court’s assessment of the reliability of evidence supporting a sentencing
    enhancement” for clear error. United States v. Martinez, 
    824 F.3d 1256
    , 1261 (10th Cir.

    Appellate Case: 21-2151      Document: 010110825909         Date Filed: 03/14/2023         Page: 7
    2016). But see id. at n.6 (stating the abuse of discretion standard may be more
    appropriate).2
    Discussion
    A. Mr. Anderson’s Suppression Arguments
    On appeal, Mr. Anderson renews his arguments that Sgt. Danius lacked reasonable
    suspicion both to stop him for committing harassment and to conduct a pat-down frisk.
    He also raises new arguments, challenging the district court’s conclusions concerning
    reasonable suspicion to stop him for violating the jaywalking ordinance and the causal
    nexus between the pat-down and the firearm he sought to suppress. He does not,
    however, challenge the court’s factual findings.
    It is well settled that, notwithstanding the Fourth Amendment’s prohibition on
    unreasonable searches and seizures, “police can stop and briefly detain a person for
    investigative purposes if the officer has a reasonable suspicion supported by articulable
    facts that criminal activity ‘may be afoot,’ even if the officer lacks probable cause.”
    United States v. Sokolow, 
    490 U.S. 1
    , 7 (1989) (quoting Terry, 
    392 U.S. at 30
    ). This is
    not “an onerous standard.” United States v. Simpson, 
    609 F.3d 1140
    , 1153 (10th Cir.
    2010). Rather, “as long as [an officer] has a particularized and objective basis for
    suspecting an individual may be involved in criminal activity, he may initiate an
    investigatory detention even if it is more likely than not that the individual is not involved
    2
    The government argues that some of Mr. Anderson’s challenges to his sentence
    are unpreserved and should be reviewed for plain error. We need not address this
    argument because we conclude that Mr. Anderson’s challenges would fail even if they
    were preserved.
    7
    Appellate Case: 21-2151     Document: 010110825909          Date Filed: 03/14/2023      Page: 8
    in any illegality.” United States v. Johnson, 
    364 F.3d 1185
    , 1194 (10th Cir. 2004).
    Furthermore, “an officer need not rule out the possibility of innocent conduct, or even
    have evidence suggesting a fair probability of criminal activity.” United States v.
    Esquivel-Rios, 
    725 F.3d 1231
    , 1236 (10th Cir. 2013) (internal quotation marks and
    citations omitted).
    a. Reasonable Suspicion for the Stop
    The district court held that Sgt. Danius reasonably suspected Mr. Anderson of
    harassment and jaywalking. Because reasonable suspicion of either offense is sufficient
    to justify a Terry stop, we need only determine whether Sgt. Danius reasonably suspected
    that Mr. Anderson committed one of these offenses.
    For the first time on appeal, Mr. Anderson asserts Sgt. Danius lacked reasonable
    suspicion that he violated the jaywalking ordinance. Specifically, he argues the
    ordinance does not proscribe walking on a road shoulder, where he was walking. Mr.
    Anderson acknowledges that he did not make this specific argument below but argues
    that the district court committed plain error.3 Mr. Anderson’s failure to raise this
    argument below constitutes waiver,4 and he does not attempt to show good cause.
    3
    He also argues that, based on Yee v. Escondido, 
    503 U.S. 519
    , 534 (1992), he is
    permitted to raise this argument on appeal because it was encompassed by his general
    argument that there was no reasonable suspicion to stop him. As the government points
    out, however, we have rejected this construction of Yee. See Parker Excavating, Inc. v.
    Lafarge West, Inc., 
    863 F.3d 1213
    , 1223 (10th Cir. 2017).
    4
    The government contends this new argument is also precluded by the conditional
    plea agreement, which gives Mr. Anderson the right to appeal the suppression decision
    only on grounds argued in district court. We need not decide this issue because we
    conclude the argument is waived.
    8
    Appellate Case: 21-2151     Document: 010110825909          Date Filed: 03/14/2023      Page: 9
    Nonetheless, Mr. Anderson’s argument would fail even under plain error review because
    it relies on a faulty reading of the ordinance, which prohibits “walk[ing] along or upon an
    adjacent roadway” if a sidewalk is provided. § 8-2-7-7(A) (emphasis added).
    Because Mr. Anderson’s new argument fails, we are not required to decide
    whether there was reasonable suspicion that he committed harassment in violation of the
    New Mexico statute. We nonetheless conclude, on de novo review, that there was
    reasonable suspicion to stop Mr. Anderson to investigate the alleged harassment. First,
    the woman who flagged Sgt. Danius down specifically claimed Mr. Anderson was
    harassing her. Second, the fact that she flagged Sgt. Danius down conveys she was
    concerned enough to seek police assistance and perhaps had significant concerns about
    her safety. Similarly, Sgt. Danius’s observation of the woman’s demeanor supports a
    reasonable suspicion that Mr. Anderson’s actions were causing her emotional distress.
    Finally, the statement “He’s not leaving me alone” indicates Mr. Anderson was engaging
    in some sort of repetitive conduct and supports a reasonable suspicion there was the
    requisite pattern of conduct. At this stage, Sgt. Danius was not required to have all the
    information and evidence needed to convict Mr. Anderson of harassment. The
    information available to him was sufficient to meet the low reasonable suspicion bar, and
    thus the district court did not err in finding there was reasonable suspicion of
    harassment.5
    5
    Mr. Anderson argues the district court violated Fed. R. Crim. P. 12(d) by not
    explaining why it rejected his argument on this issue. To the contrary, the court
    recounted many facts that “amply support a reasonable suspicion of harassment.” Rec.,
    vol. I at 141.
    9
    Appellate Case: 21-2151         Document: 010110825909      Date Filed: 03/14/2023     Page: 10
    Therefore, Sgt. Danius did not violate Mr. Anderson’s Fourth Amendment rights
    by initiating a Terry stop.
    b. The Pat-Down Frisk
    During an investigative stop, an officer may conduct a limited search for weapons
    if “a reasonably prudent man in the circumstances would be warranted in the belief that
    his safety or that of others was in danger.” Terry, 
    392 U.S. at 27
    . The parties dispute
    whether Sgt. Danius had the reasonable suspicion necessary to conduct the pat-down
    frisk of Mr. Anderson. We need not decide this issue because Mr. Anderson has failed to
    show there was a causal nexus between the pat-down and the discovery of the firearm.
    See United States v. Goebel, 
    959 F.3d 1259
    , 1268 (10th Cir. 2020); United States v.
    Nava-Ramirez, 
    210 F.3d 1128
    , 1131 (10th Cir. 2000) (defendant bears the burden of
    showing a nexus between the alleged violation and the challenged evidence).
    Mr. Anderson argues that the pat-down prolonged the stop and led to the discovery
    of the firearm. An unreasonably prolonged detention is unconstitutional. United States v.
    Samilton, 
    56 F.4th 820
    , 827 (10th Cir. 2022). However, even if a defendant shows that a
    detention was impermissibly prolonged, evidence will only be suppressed if he can
    “establish a causal link between the violation and the discovery of the contested
    evidence.” Goebel, 959 F.3d at 1268. “Evidence will not be suppressed as fruit of the
    poisonous tree unless an unlawful search is at least the but-for cause of its discovery.”
    United States v. Chavira, 
    467 F.3d 1286
    , 1291 (10th Cir. 2006) (emphasis in original).
    We agree with the district court and the government that Mr. Anderson failed to
    show a causal nexus between the pat-down and the discovery of the firearm. Critically,
    10
    Appellate Case: 21-2151      Document: 010110825909         Date Filed: 03/14/2023     Page: 11
    no evidence was found during the pat-down. The firearm was instead found in a search
    incident to Mr. Anderson’s arrest for concealing his identity.
    It is undeniable that the frisk prolonged the stop. But Mr. Anderson would have
    been arrested and the gun would have been discovered regardless of the pat-down. Sgt.
    Danius asked Mr. Anderson if he had identification before initiating the pat-down. In
    fact, body camera footage shows Sgt. Danius asked this question within about thirty
    seconds of getting out of his vehicle and approaching Mr. Anderson. It thus appears Sgt.
    Danius was interested in ascertaining Mr. Anderson’s identity from the inception of the
    stop.
    Moreover, there is no evidence to suggest that Sgt. Danius’s reasons for
    continuing to inquire into Mr. Anderson’s identity were derived from the pat-down. It is
    well-established “that questions concerning a suspect’s identity are a routine and
    accepted part of many Terry stops.” Hiibel v. Sixth Judicial Dist. Court of Nev.,
    Humboldt Cty., 
    542 U.S. 177
    , 186 (2004). This questioning allows law enforcement to
    determine whether the suspect has any outstanding warrants or a history of violence or
    mental illness and helps officers assess personal and public safety. 
    Id.
     Indeed, Sgt.
    Danius testified at the suppression hearing that identifying involved parties is “police
    work 101.” Rec., vol. IV at 41. Sgt. Danius was also entitled to request Mr. Anderson’s
    identification to cite him for violating the jaywalking ordinance.
    Notably, Mr. Anderson does not argue that anything about the pat-down led him to
    repeatedly lie about his identity. He was a felon in possession of a loaded firearm with
    outstanding arrest warrants. Being truthful about his identity was certain to lead to an
    11
    Appellate Case: 21-2151      Document: 010110825909          Date Filed: 03/14/2023    Page: 12
    arrest and further charges, and his incentives to conceal his identity were not altered by
    any extension of the stop required to conduct the frisk.
    For these reasons, we are not persuaded that the pat-down was the but-for cause of
    the discovery of the firearm.
    B. Sentencing Enhancement
    At sentencing, Mr. Anderson objected to the application of the § 2K2.1(b)(6)(B)
    enhancement for possessing a firearm in connection with another felony. He argued there
    was insufficient evidence to find that he possessed methamphetamine.6 The district court
    denied Mr. Anderson’s objection, holding that the government met its burden in proving
    the enhancement applied by a preponderance of the evidence. In doing so, it cited the
    attachments to the government’s sentencing memorandum including the criminal
    complaint, a police report authored by Sgt. Danius, and the related state indictment. Id.
    at 116. Of importance to the court, the police report stated that the substance found in
    Mr. Anderson’s sock tested positive for methamphetamine and that Sgt. Danius observed
    evidence consistent with narcotics trafficking. Id. The court also highlighted that Mr.
    Anderson had been charged with drug trafficking in state court in connection with the
    instant arrest. Id.
    6
    Mr. Anderson also argued the government violated Fed. R. Crim. P. 16 and the
    district court’s discovery order by failing to produce additional evidence of
    methamphetamine possession. The district court denied Mr. Anderson’s oral motion
    because he did not file a written motion even though Probation had made clear in the PSR
    disclosed months prior that it was recommending the enhancement.
    12
    Appellate Case: 21-2151     Document: 010110825909          Date Filed: 03/14/2023     Page: 13
    On appeal, Mr. Anderson challenges the enhancement on multiple grounds. He
    begins by arguing that the government provided inaccurate information to the district
    court because the prosecutor erroneously stated at sentencing that testimony about
    methamphetamine was given at the preliminary and suppression hearings. But Mr.
    Anderson did not object to the misstatement and there is no evidence that it was material
    to the district court, which did not mention any such testimony when denying the
    objection or otherwise.
    He similarly contends the district court erred in recounting the information in the
    police report. The court said Sgt. Danius stated in the report that “possession of multiple
    packaging materials (clear plastic baggies) and containers (black box) as well as
    individually packaged narcotics was consistent with narcotics sales and trafficking.” Id.
    The court continued: “In addition, Mr. Anderson . . . was in possession of drug
    paraphernalia, as indicated in the report.” Id. (emphasis added). Mr. Anderson argues
    that the police report does not mention paraphernalia other than the clear plastic baggies
    and black box. However, the government aptly points out that the police report identifies
    “another small clear container” as “drug paraphernalia.” Rec., vol. II at 66. Furthermore,
    a reading of the sentencing transcript alongside the police report makes clear that the
    court was referencing two separate statements in the police report: one describing Mr.
    Anderson’s possession of drug paraphernalia and one drawing the conclusion that the
    paraphernalia was consistent with drug trafficking. There is no indication that the district
    court was relying on evidence that did not exist or was not presented.
    13
    Appellate Case: 21-2151      Document: 010110825909         Date Filed: 03/14/2023        Page: 14
    Mr. Anderson next argues it was improper for the district court to rely on the state
    charge because it was dismissed. But Mr. Anderson is not entitled to a favorable
    inference from this dismissal. See United States v. Farnsworth, 
    92 F.3d 1001
    , 1005 n.2,
    1010 (10th Cir. 1996) (referencing dismissed state charges in upholding the district
    court’s application of § 2K2.1(b)(6)(B)7); Gambino-Zavala, 
    539 F.3d at
    1230 n.3
    (sentence can be enhanced on the basis of uncharged or acquitted conduct); United States
    v. Ruby, 
    706 F.3d 1221
    , 1230 (10th Cir. 2013) (acquittal in state court under the beyond a
    reasonable doubt standard bears little weight on whether the preponderance standard can
    be met at federal sentencing). In fact, the PSR states the charges were dropped due to the
    instant federal case.
    Most notably, Mr. Anderson argues for the first time that it was improper for the
    court to rely on a police report not admitted into evidence without specifically
    determining that it was reliable. In doing so, Mr. Anderson relies on our unpublished
    decision in United States v. Padilla, 
    793 F. App’x 749
     (10th Cir. 2019). There, the
    defendant’s offense level was increased based on information in a police report that was
    not admitted into evidence or supported by corroborating evidence. 
    Id. at 762
    . We held
    the district court was required to “make an on-the-record, individualized reliability
    assessment” before relying on the report. 
    Id.
     However, we explained that a sentencing
    court can rely on information in an unadmitted police report if the record contains
    7
    Section 2K2.1(b)(6)(B) was previously numbered 2K2.1(b)(5).
    14
    Appellate Case: 21-2151      Document: 010110825909          Date Filed: 03/14/2023        Page: 15
    corroborative evidence and the relevant information is summarized somewhere in the
    record (e.g., the PSR). 
    Id.
     at 758 n.5.
    Although Padilla is non-binding, it is also easily distinguishable from the instant
    case in two material ways. First, the police report in Padilla was not part of the record at
    all and had not been disclosed in discovery. 
    Id. at 752
    . Here, the police report and the
    criminal complaint were exhibits to both the government’s opposition to the motion to
    suppress and its sentencing memorandum. The government also submitted the state
    indictment charging Mr. Anderson with trafficking methamphetamine as an exhibit to its
    sentencing memorandum. Although none of these documents were admitted into
    evidence at a hearing, they were part of the record and Mr. Anderson had the opportunity
    to test the reliability of the police report at the suppression hearing by cross examining
    Sgt. Danius.
    Second, the police report here is strongly corroborated by Sgt. Danius’ body
    camera footage, which was admitted into evidence at the suppression hearing. The video
    depicts officers recovering a substance stored in the manner described in the report.
    Consistent with the report, Mr. Anderson is recorded in the video claiming the alleged
    drugs were fake. The video also includes audio of Mr. Anderson admitting the substance
    from his sock “may be real,” which supports application of the enhancement. The
    veracity of the police report is further supported by the district court’s repeated finding
    that Sgt. Danius was a credible witness. Although police reports are not inherently
    reliable, see Ruby, 
    706 F.3d at 1230
    , the police report here has significant indica of
    15
    Appellate Case: 21-2151        Document: 010110825909         Date Filed: 03/14/2023       Page: 16
    reliability and allowed the district court to properly determine, by a preponderance of the
    evidence, that Mr. Anderson was engaged in drug trafficking.
    Importantly, Mr. Anderson did not challenge the reliability of the police report in
    district court. Rather, he argued instead that the government’s exhibits were not
    evidence, did not provide enough information, were not subject to cross examination, and
    omitted evidence favorable to Mr. Anderson.
    We recently held in United States v. McDonald, 
    43 F.4th 1090
    , 1096 (10th Cir.
    2022), that Padilla was “incorrect” in concluding that our prior caselaw determined the
    issue of “whether a mere objection to the reliability of the evidence in the PSR is
    sufficient to trigger a district court’s fact-finding obligation.” In McDonald, the
    defendant made several objections to facts in the PSR, arguing “that the source of the
    information was not credible or reliable.” 
    Id.
     We clarified that “[a]ttacking a witness’s
    credibility or reliability is different than asserting that their statements or information are
    false.” 
    Id. at 1097
    . Thus, to trigger a district court’s fact-finding obligation, a defendant
    must affirmatively “make a showing that the information in the [PSR] was unreliable and
    articulate the reasons why the facts contained therein were untrue or inaccurate.” 
    Id. at 1096
     (quoting United States v. Chee, 
    514 F.3d 1106
    , 1115 (10th Cir. 2008)) (emphasis
    and alteration in original). “In other words, the defendant must assert that the facts
    alleged . . . are false.” Id. at n.3.
    Although Mr. Anderson objected to the claim that he possessed
    methamphetamine, he did not contend in district court that specific statements in the
    police report were false and does not do so on appeal. For example, he does not argue
    16
    Appellate Case: 21-2151      Document: 010110825909          Date Filed: 03/14/2023      Page: 17
    that he did not possess a crystal-like substance which appeared to Sgt. Danius to be
    methamphetamine, nor that the substance was not stored in the manner described in the
    report or did not test presumptively positive for methamphetamine in a field test. Instead,
    Mr. Anderson now argues the police report was insufficient to support the enhancement
    because it was not admitted into evidence, was not corroborated by other evidence, and
    was not determined to be reliable. We disagree. The police report was twice included in
    the record, corroborated by the body camera footage and the state indictment, and
    authored by a witness deemed credible by the district court. This was sufficient for the
    court to rely upon it in applying § 2K2.1(b)(6)(B).
    C. Brady Claim
    On appeal, Mr. Anderson also asserts the government failed to disclose evidence
    of methamphetamine possession in violation of Brady v. Maryland, 
    373 U.S. 83
     (1963).
    In particular, he points out that the government did not disclose photographs of the drugs,
    additional test results, or information about the field test used. He argues this failure to
    disclose prevented him from challenging the evidence used to enhance his sentence.
    To establish a Brady violation, a defendant must show the government suppressed
    material evidence that was favorable to him. United States v. Acosta-Gallardo, 
    656 F.3d 1109
    , 1117 (10th Cir. 2011). Mere speculation about whether evidence would have been
    favorable to the defendant is insufficient to support a Brady claim. See 
    id.
     Particularly
    because Mr. Anderson was indicted in state court for trafficking methamphetamine, it is
    likely some of the evidence he requested exists. We need not speculate, however,
    17
    Appellate Case: 21-2151     Document: 010110825909        Date Filed: 03/14/2023    Page: 18
    because Mr. Anderson has not shown any such evidence would be favorable to him. His
    Brady claim therefore fails.
    Conclusion
    We are not persuaded that the firearm was discovered in violation of Mr.
    Anderson’s Fourth Amendment rights or that the district court miscalculated the
    applicable sentencing guidelines. Accordingly, we affirm the denial of his motion to
    suppress, as well as his sentencing enhancement.
