    ____________
    Appeal from United States District Court
    for the District of North Dakota - Eastern
    ____________
    Submitted: December 17, 2021

    ____________
    Before SMITH, Chief Judge, GRUENDER and KOBES, Circuit Judges.
    ____________
    SMITH, Chief Judge.
    A jury convicted Jose Alberto Perez of two federal controlled substance
    offenses1 and three firearms offenses.2 Prior to trial, Perez filed a motion to suppress
    1
    Perez was convicted of (1) conspiracy to possess with intent to distribute and
    distribute a controlled substance, in violation of 
    18 U.S.C. § 2
     and 21 U.S.C.
    evidence alleging that the police search of his car violated his constitutional rights.
    The district court3 denied Perez’s motion. During trial, Perez objected to a comment
    that the government made during its closing argument and moved for a mistrial. The
    district court denied this motion as well. On appeal, Perez seeks reversal of the denial
    of his motion to dismiss and his mistrial motion. The district court did not err as to
    either ruling and we, therefore, affirm.
    I. Factual Background
    A. The Traffic Stop
    On February 20, 2018, North Dakota Highway Patrol (NDHP) Trooper Brett
    Mlynar, while parked on a median on U.S. Highway 2, spoke to a driver who pulled
    up next to him. The driver reported a red sedan driving westbound in an eastbound
    lane near a rest area on Highway 2. The driver also said that someone was chasing the
    red sedan. Trooper Mlynar, with his drug-sniffing dog, K9 Castor, drove in the
    direction of the reported red sedan. He observed a red Chevrolet Impala at a stop sign
    at a rest area waiting to turn westbound onto Highway 2. Trooper Mlynar noticed the
    extremely dark tint on the Impala’s windows. He believed that the Impala’s windows
    were tinted darker than state law allowed. After the Impala drove past him, he
    initiated a traffic stop.
    § 841(a)(1) and (b)(1)(A), and (2) possession with intent to distribute a controlled
    substance, in violation of 
    18 U.S.C. § 2
     and 
    21 U.S.C. § 841
    (a)(1) and (b)(1)(A).
    2
    Perez was convicted of (1) possession of firearms in furtherance of drug
    trafficking crimes, in violation of 
    18 U.S.C. §§ 2
     and 924(c)(1)(A) and (c)(1)(B)(i);
    (2) possession of a firearm made in violation of the National Firearms Act, in
    violation of 
    18 U.S.C. § 2
     and 
    26 U.S.C. §§ 5822
    , 5861(c), and 5871; and (3)
    possession of firearms and ammunition by a convicted felon, in violation of 
    18 U.S.C. §§ 2
    , 922(g)(1), and 924(a)(2).

    The Honorable Peter D. Welte, Chief Judge, United States District Court for
    the District of North Dakota.
    -2-
    Trooper Mlynar approached the Impala and spoke with the driver, Perez. Perez
    was wearing a black gaiter pulled down around his neck and a black glove on his left
    hand. Trooper Mlynar measured the window tint and determined that the tint violated
    state law. He asked Perez for identification, vehicle registration, and proof of
    insurance. Perez said he had no ID because he left his driver’s license at a hotel in
    Nebraska. He then admitted that his license was suspended. He could not provide
    proof of registration or insurance and neither could his two passengers. The
    passengers gave discrepant answers as to the Impala’s ownership.
    Trooper Mlynar directed Perez to get out of the Impala and to come to his
    patrol car. Trooper Mlynar thought he saw Perez hiding or reaching for something as
    he was coming out of the Impala, so Trooper Mlynar ordered Perez to show his
    hands. Perez exited the Impala without incident. While they were walking to the
    patrol car, Trooper Mlynar asked Perez if he had any weapons on his person. Perez
    denied having any weapons and consented to a pat-down search. Trooper Mlynar
    found a knife with a four-inch blade in Perez’s front pants pocket. Afterwards,
    Trooper Mlynar placed Perez in handcuffs but advised him that he was not under
    arrest. Trooper Mlynar conducted a second pat-down and found multiple cell phones
    and Perez’s Texas driver’s license taped to one of the phones.
    Trooper Mlynar then escorted Perez to the front seat of his patrol car. Trooper
    Mlynar began asking Perez questions, and Perez admitted that he had driven the
    wrong way down the highway. He blamed his error on lack of familiarity with the
    area. Trooper Mlynar left Perez in the patrol car and returned to the Impala to speak
    with Perez’s passengers. Their accounts did not match Perez’s.
    After returning to his patrol car, Trooper Mlynar received notice from the
    North Dakota Department of Emergency Services’ Division of State Radio that
    Perez’s Texas driver’s license was suspended and expired. He also learned that Perez
    had an active, non-extraditable Colorado arrest warrant for drug charges. At that
    -3-
    point, Trooper Mlynar determined that he was going to charge Perez with driving
    with a suspended license.
    Trooper Mlynar requested assistance from the Ramsey County Sheriff’s Office.
    Trooper Mlynar told Perez that he would issue Perez a warning for the window tint
    violation. Trooper Mlynar asked Perez for consent for K9 Castor to sniff the Impala’s
    exterior. Perez did not consent. Trooper Mlynar testified that it was NDHP protocol
    to request consent for a search prior to deploying a drug-sniffing dog, but to proceed
    with the search regardless.
    Soon after Trooper Mlynar called for backup, another car drove up and parked
    in front of the Impala. The driver identified herself as Fran Redday. She told Trooper
    Mlynar that she wanted to take the Impala and drive its passengers home and that she
    would come back for her car later. She had no proof of ownership of the Impala or
    proof of permission to drive it. Trooper Mlynar denied her request.
    Trooper Mlynar turned his attention back to Perez and informed him that he
    was under arrest for driving with a suspended license. Before moving Perez to the
    back seat of the patrol car, he did a third pat-down and discovered an empty holster
    tucked into the front waistband of Perez’s pants. Inside Perez’s pants pocket, Trooper
    Mlynar found a handkerchief with five .45 caliber bullets inside.
    Ramsey County Deputy Ted Rainesalo arrived on the scene. Trooper Mlynar
    and Deputy Rainesalo directed Perez’s passengers to exit the Impala. Trooper Mlynar
    deployed K9 Castor to sniff the Impala’s exterior beginning on the rear bumper on
    the passenger side. He conducted an “initial free pass”—a search where the handler
    does not provide the dog any direction—going toward the front of the Impala. R. Doc.
    195, at 166. During the initial free pass, he recognized that K9 Castor displayed alert
    behavior. He then conducted a “spin out” and began a “detailed systematic
    search”—a search where the handler taps the side of the car high and low to direct the
    -4-
    dog to check specific areas—on the passenger side. 
    Id.
     Trooper Mlynar and the
    government’s expert, NDHP Trooper Kyle Stern, testified that the initial free pass,
    the spin out, and the detailed systematic search were standard practices.
    K9 Castor indicated that she had picked up a scent by laying down near the
    Impala’s rear wheel on the passenger side. Based on her indication, Trooper Mlynar
    decided to do a physical search of the Impala. Deputy Rainesalo assisted. Between
    the front passenger seat and the center console, they found 24 grams of
    methamphetamine. Inside a duffle bag on the back seat, they found one gram of
    marijuana, 43 empty clear plastic bags, and a laptop computer. In the center console,
    they found two debit cards that did not belong to any of the Impala’s occupants. On
    the floor of the back seat under a jacket, they found a short-barreled shotgun and five
    shotgun shells. On the floor of the back seat on the passenger side, they found a .45
    caliber handgun with a bullet in the chamber and four bullets in the magazine. They
    also found multiple cell phones. The Impala’s roof appeared to have been damaged
    by shotgun fire.
    Trooper Mlynar contacted his supervisor, Sergeant Adam Dvorak, described
    what they found in the Impala, and explained that the registered owner was not
    present and that he did not know whether anyone present could take possession of the
    Impala. Sergeant Dvorak advised impounding the Impala. NDHP’s impoundment
    policy states, in relevant part, “If the owner does not provide for the vehicle’s
    removal and the vehicle constitutes a hazard, the officer must arrange for the
    vehicle’s removal and [an inventory search form] shall be completed.” R. Doc. 166-4,
    at 13. During his testimony, Trooper Mlynar agreed that “leaving [the Impala] on the
    roadside just posed a risk . . . that it could be taken by somebody who didn’t have
    authority to take it” and that “it was probably a good idea not to leave it out in the
    middle of Highway 2.” R. Doc. 195, at 117.
    -5-
    After speaking with his supervisor, Trooper Mlynar called a tow truck to take
    the Impala to the impound lot. Before the tow truck arrived, Trooper Mlynar
    conducted “a brief inventory” search at the scene in “low light conditions.” R. Doc.
    166-2, at 6. He testified that, at the time of the search, “[i]t was getting dark. The sun
    was setting.” R. Doc. 195, at 114. He also testified that Perez was still in the back seat
    of his patrol car, that K9 Castor was in her kennel in the back of his patrol car, and
    that the tow truck was pulling up. During this first inventory search, he found no
    contraband.
    Trooper Mlynar completed an NDHP inventory form, listing the reason for the
    hold on the Impala as “Pending Investigation.” R. Doc. 179-1. At a state court
    hearing, when asked whether he was familiar with NDHP written protocols for
    inventory searches, he responded “not verbatim.” R. Doc. 166-12, at 39. He testified
    in front of the magistrate judge that he was “[p]retty familiar with” the written
    impound procedures. R. Doc. 196, at 11. The Impala was towed to a fenced and
    locked impound lot. Trooper Mlynar followed the tow truck to the lot and confirmed
    that the Impala was locked before he left the lot.
    Perez was arrested on state drug charges and for driving with a suspended
    license and booked into the local jail. During booking, a dispatcher fielded a call from
    a woman who said that she had heard that her car was involved in a traffic stop on
    Highway 2. When Trooper Mlynar returned her call, the woman said she was the
    daughter of the Impala’s registered owner. He then called the registered owner,
    Clarine Young Bird, who lived approximately three hours from the scene of the traffic
    stop. Young Bird provided the following information: she verified that she owned the
    Impala; she said that her daughter had been using the Impala in Bismarck, North
    Dakota; she said that she did not know Perez nor his passengers; and she said that she
    had not given them permission to use the Impala. Although Young Bird’s daughter
    told Trooper Mlynar that the Impala had been taken from a Bismarck parking lot,
    there was no report of the Impala having been stolen.
    -6-
    B. Subsequent Search of the Impala
    Four days after the traffic stop, Trooper Mlynar went to the impound lot and
    searched the Impala again because the first search had been rushed and he did not
    want to risk anything of value not being accounted for. During this second inventory
    search, he found two additional handguns, three plastic bags containing
    methamphetamine, and a cell phone behind the back rest of the back seat. After he
    found these items, he terminated the search and applied for a search warrant. Two
    days after the impound lot search, pursuant to a warrant issued by a state court, he
    searched the Impala a third time. He found more ammunition, 459 grams of
    methamphetamine, drug paraphernalia, and a stun gun. The Impala was later released
    to its registered owner.
    II. Procedural Background
    A. Motion to Suppress
    In July 2018, Perez and his passengers were indicted by a federal grand jury.
    In October 2019, Perez filed a motion to suppress evidence. A magistrate judge held
    an evidentiary hearing in January 2020 and issued a report and recommendation in
    June 2020. Based on the evidence, and relying on Rodriguez v. United States, 
    575 U.S. 348
     (2015), the magistrate judge denied Perez’s suppression motion. The
    magistrate judge concluded that no Fourth Amendment violation occurred because
    the stop’s continuation for the dog sniff did not unreasonably prolong the stop given
    the attendant facts, such as the lack of proof of registration, insurance, and ownership,
    and Perez’s lack of candor.
    As to the Impala’s impoundment and the two subsequent searches, the
    magistrate judge held, “There is no evidence suggesting Trooper Mlynar did not
    properly follow the [NDHP’s impound] policy’s requirements for completing an
    inventory form or did not follow any other provision of the policy.” R. Doc. 209, at
    37. The magistrate judge concluded that it was reasonable under the policy for
    Trooper Mlynar to impound the Impala and, given the firearms and drugs found
    -7-
    during the first search of the Impala, that there was probable cause to seize it under
    United States v. Sims, 
    424 F.3d 691
     (8th Cir. 2005). The magistrate judge determined
    that once the Impala was impounded, the warrantless search based on NDHP’s
    inventory policy was justified.
    The magistrate judge held, “Trooper Mlynar permissibly concluded there was
    a particularized and objective basis for suspecting Perez was ‘involved in wrongdoing
    beyond committing traffic violations.’” R. Doc. 209, at 29 (quoting United States v.
    Sanchez, 
    955 F.3d 669
    , 675 (8th Cir. 2020)). The magistrate judge concluded that K9
    Castor’s sniff was lawful under Illinois v. Caballes, 
    543 U.S. 405
    , 409 (2005). On the
    training of K9 Castor and Trooper Mlynar and K9 Castor’s reliability, the magistrate
    judge held that “a preponderance of the evidence demonstrates K9 Castor’s
    certification was adequate under the standards of Florida v. Harris[, 
    568 U.S. 237
    (2013)].” R. Doc. 209, at 30.
    On the search warrant for the Impala, the magistrate judge concluded that “the
    warrant application did not include material misstatements of fact and/or omissions
    of material facts about K9 Castor’s reliability.” Id. at 38. Lastly, the magistrate judge
    held that search warrants for the electronic devices found inside the Impala and the
    social media accounts for the individuals involved in the traffic stop did not lack
    particularity and were not overbroad.
    The district court adopted the magistrate judge’s report and recommendation
    without comment.
    B. Motion for a Mistrial
    After the government’s closing statement, Perez requested a sidebar and made
    the following arguments:
    I believe that [the government] made an improper comment on [Perez’s] failure
    to testify. [The government] stated that evidence showed that . . . Perez was
    -8-
    selling drugs and that that was uncontroverted. Literally the only person who
    could controvert that would be . . . Perez. According to Griffin v. California,
    
    380 U.S. 609
     (1965)[,] and U.S. v[.] Robinson, 
    485 U.S. 25
     (1988), there
    should be no comment by the prosecution in closing argument about the
    defendant’s right to remain silent. To do so is improper[,] and I’m requesting
    a mistrial.
    R. Doc. 305, at 30. The district court denied the motion, ruling that:
    The [c]ourt finds . . . that the argument made by the United States was not a
    violation of the prohibition against mentioning the defendant’s failure to
    testify. It did not approach that. It was . . . in reference to the evidence that was
    heard at trial from all witnesses and presented through all witnesses and
    exhibits. The objection is overruled.
    
    Id. at 32
    .
    III. Discussion
    A. Motion to Suppress
    Perez makes the following arguments regarding his motion to suppress: (1) the
    Impala was impermissibly seized, (2) the Impala was illegally impounded and
    searched following impoundment, (3) K9 Castor lacked the requisite accuracy and
    reliability to establish probable cause for the search of the Impala conducted after her
    sniff, and (4) the state court warrants were improperly issued because of omissions
    in the warrant applications and because the evidence supporting the warrants was the
    fruit of unlawful searches and seizures.
    “A mixed standard of review applies to the denial of a motion to suppress
    evidence. We review the district court’s findings of fact under the clearly erroneous
    standard, and the ultimate conclusion of whether the Fourth Amendment was violated
    is subject to de novo review.” United States v. Williams, 
    777 F.3d 1013
    , 1015 (8th
    Cir. 2015) (internal quotation marks omitted). “This court will affirm the district
    -9-
    court’s denial of a motion to suppress evidence unless it is unsupported by substantial
    evidence, based on an erroneous interpretation of applicable law, or, based on the
    entire record, it is clear a mistake was made.” United States v. Hogan, 
    539 F.3d 916
    ,
    921 (8th Cir. 2008) (internal quotation marks omitted).
    1. Seizure of the Impala
    Perez argues that the Impala was impermissibly seized because the traffic
    infraction that formed the basis for the stop—the Impala’s illegal window
    tinting—was resolved after he was arrested for driving with a suspended license. He
    argues that the Impala should have been released to Redday at that point. He contends
    that the magistrate judge incorrectly analyzed the continued seizure of the Impala
    under the reasonable-suspicion standard and that probable cause was the correct
    standard because Redday asked Trooper Mlynar to release the Impala to her. He
    argues that the district court erred by adopting the magistrate judge’s analysis. We
    disagree and affirm.
    “An officer conducting a traffic stop who discovers information leading to
    reasonable suspicion of an unrelated crime may extend the stop and broaden the
    investigation.” United States v. Woods, 
    829 F.3d 675
    , 679 (8th Cir. 2016). “A delay
    that ‘prolongs—i.e., adds time to—the stop,’ to conduct investigatory actions
    unrelated to the purposes of the stop is impermissible unless it is supported by
    reasonable suspicion.” Sanchez, 955 F.3d at 674 (quoting Rodriguez, 575 U.S. at
    357).4
    The magistrate judge correctly applied the reasonable-suspicion standard in
    assessing whether the Impala was impermissibly seized under the totality of the
    4
    The cases upon which Perez relies in arguing that probable cause is the correct
    standard—Carroll v. United States, 
    267 U.S. 132
     (1925), and Collins v. Virginia, 
    138 S. Ct. 1663
     (2018)—address the automobile exception outside the context of a traffic
    stop.
    -10-
    circumstances. See United States v. Callison, 
    2 F.4th 1128
    , 1132 (8th Cir. 2021)
    (holding that inconsistent answers to routine travel questions contributed to
    reasonable suspicion); Sanchez, 955 F.3d at 675 (concluding that the fact that
    someone would lend his car to unlicensed drivers, especially if one of those drivers
    could not readily name the owner, contributed to reasonable suspicion). Trooper
    Mlynar did not illegally seize the Impala because he justifiably extended the traffic
    stop.
    2. Impoundment and Second Inventory Search of the Impala
    Perez argues that the Impala was unlawfully impounded because a willing
    driver was available and that the impoundment did not follow NDHP’s impound
    policy.
    The impounding of a vehicle passes constitutional muster so long as the
    decision to impound is guided by a standard policy—even a policy that
    provides officers with discretion as to the proper course of action to take—and
    the decision is made “on the basis of something other than suspicion of
    evidence of criminal activity.”
    United States v. Le, 
    474 F.3d 511
    , 514 (8th Cir. 2007) (quoting Colorado v. Bertine,
    
    479 U.S. 367
    , 375 (1987)).
    NDHP’s impoundment policy states, in relevant part, “If the owner does not
    provide for the vehicle’s removal and the vehicle constitutes a hazard, the officer
    must arrange for the vehicle’s removal and [an inventory search form] shall be
    completed.” R. Doc. 166-4, at 13. We conclude that Trooper Mlynar’s decision to
    impound the Impala was guided by NDHP’s policy and that the decision was made
    on the basis of something other than suspicion of evidence of criminal activity.
    Trooper Mlynar was permitted to conduct a second inventory search of the
    Impala four days after it was impounded. The initial inventory search on the side of
    -11-
    the highway while he was waiting for the tow truck was rushed. Following
    impoundment, “[p]olice may conduct a warrantless search of a lawfully-impounded
    vehicle even in the absence of probable cause.” United States v. Kennedy, 
    427 F.3d 1136
    , 1143 (8th Cir. 2005). “The central question in evaluating the propriety of an
    inventory search is whether, in the totality of the circumstances, the search was
    reasonable.” 
    Id.
     “[I]nventories pursuant to standard police procedures are
    reasonable.” South Dakota v. Opperman, 
    428 U.S. 364
    , 372 (1976).
    The propriety of a second inventory search is an issue of first impression for
    our court, but the Second Circuit addressed this issue in United States v. Williams,
    
    930 F.3d 44
     (2d Cir. 2019). The defendant in Williams had moved to suppress a
    loaded firearm found during a second inventory search of a rental car that he was
    driving on the day of his arrest. 
    Id. at 50
    . Detectives had commenced an initial
    inventory search after they brought the defendant to the local jail to process his arrest
    and did not find any contraband. 
    Id. at 51
    . After the defendant learned the rental car
    was going to be towed to the rental agency, he became alarmed and asked for his
    phone call. 
    Id.
     A detective overheard him say “at a high pitch and fast pace,” which
    the detective took to indicate that his “stress level was elevated,” that the individual
    on the receiving end of the call needed to “‘come get this car right now’ because the
    police were ‘looking to tow it.’” 
    Id.
     This prompted the detectives to conduct the
    second inventory search, during which they found the firearm at issue. 
    Id.
     at 51–52.
    The defendant in Williams principally argued that the second inventory search
    was impermissible because the patrol guide in that case was silent as to the validity
    of multiple inventory searches. 
    Id. at 55
    . Perez makes a similar argument. The Second
    Circuit rejected this argument, reasoning that every detail of search procedure need
    not be governed by a standardized policy and that “[a] police department’s procedures
    must simply be adequate to ‘safeguard the interests protected by the Fourth
    Amendment.’” 
    Id.
     (quoting United States v. Lopez, 
    547 F.3d 364
    , 371 (2d Cir. 2008)).
    It held that the second inventory search did not run afoul of that principle, even if
    -12-
    such a search was not specifically provided for in the patrol guide. 
    Id.
     We have
    similarly held “[r]equiring an officer to conduct an inventory search pursuant to
    ‘standardized criteria’ or an ‘established routine’ does not mean that the search must
    be made in a ‘totally mechanical’ fashion.” Kennedy, 
    427 F.3d at 1143
     (quoting
    United States v. Petty, 
    367 F.3d 1009
    , 1012 (8th Cir. 2004)).
    The Second Circuit in Williams, acknowledging that “the ultimate touchstone
    of the Fourth Amendment is ‘reasonableness,’” held that it was reasonable for
    detectives to conclude that the defendant’s behavior “suggested a need to go back and
    check their work in connection with the inventory search that they had just
    performed.” 930 F.3d at 55 (quoting Brigham City v. Stuart, 
    547 U.S. 398
    , 403
    (2006)). “[W]hether a search and seizure is unreasonable within the meaning of the
    Fourth Amendment depends upon the facts and circumstances of each case . . . .”
    Cooper v. California, 
    386 U.S. 58
    , 59 (1967). While here there was no tip that
    prompted Trooper Mlynar to conduct his second inventory search, his second search
    was also reasonable given the rushed circumstances of his first search.
    We conclude that Trooper Mlynar’s second inventory search was reasonable
    because it was done in accordance with the general police routine of taking an
    accounting of items in police custody to protect the owner’s property and also to
    protect the police against disputes over unaccounted-for property.
    3. Search of the Impala After K9 Castor’s Sniff
    Perez argues that K9 Castor lacked the requisite accuracy and reliability set
    forth in Florida v. Harris to establish probable cause for the search of the Impala
    conducted after her sniff.
    “We review de novo the district court’s legal determination of probable cause.”
    United States v. Gonzalez, 
    781 F.3d 422
    , 429 (8th Cir. 2015).
    -13-
    [T]he framework courts should use to determine whether a drug dog sniff is
    reliable enough to give police officers probable cause to conduct a search . . . .
    is “whether all the facts surrounding a dog’s alert, viewed through the lens of
    common sense, would make a reasonably prudent person think that a search
    would reveal contraband or evidence of a crime.”
    United States v. Holleman, 
    743 F.3d 1152
    , 1157 (8th Cir. 2014) (quoting Harris, 
    568 U.S. at 248
    ).
    Our review of the record satisfies us that the government sufficiently
    established K9 Castor’s accuracy and reliability such that her alert could supply
    probable cause to search.
    If a bona fide organization has certified a dog after testing his reliability
    in a controlled setting, a court can presume (subject to any conflicting
    evidence offered) that the dog’s alert provides probable cause to search.
    The same is true, even in the absence of formal certification, if the dog
    has recently and successfully completed a training program that
    evaluated his proficiency in locating drugs.
    Harris, 
    568 U.S. at
    246–47. “This presumption may be overcome if a defendant can
    show, either through cross-examination or introducing his own fact or expert witness,
    the inadequacy of a certification or training program or that the circumstances
    surrounding a canine alert undermined the case for probable cause.” Gonzalez, 781
    F.3d at 429.
    Perez’s arguments about K9 Castor’s certification and reliability testing and
    Trooper’s Mlynar’s training and handling lack merit. Though not trained by an
    outside organization, K9 Castor was certified using the same
    Polizeispuerhandpruefrung (PSP)-based certification protocol that the Wyoming
    Police Service Dog Association uses. She was also trained using a program that
    consists of 200 hours of training and that is approved by the North Dakota Peace
    Officer Standards Training Board. Lastly, the NDHP certification test requires
    -14-
    handlers to score 80 percent or higher on two written tests and the dog-and-handler
    team to pass a final test before initial certification. We find that K9 Castor has been
    certified by a bona fide organization. K9 Castor’s reliability also passes muster
    because the record shows that before her certification tests, other dogs proofed the
    search area by ensuring that no other odors of controlled substances were present
    beyond what the certifying official had placed there.
    In addition to challenging K9 Castor’s certification, Perez argues that her sniff
    was unreliable because she has previously falsely indicated the presence of drugs
    during training. Her degree of accuracy, however, is higher than the accuracy rates
    of other drug-sniffing dogs which have been deemed reliable. See Holleman, 743
    F.3d at 1157 (affirming the denial of a motion to suppress evidence discovered as a
    result of a sniff by a dog with 57 percent “in-field” accuracy); United States v.
    Donnelly, 
    475 F.3d 946
    , 955 (8th Cir. 2007) (affirming the denial of a motion to
    suppress evidence discovered as a result of a sniff by a dog with 54 percent in-field
    accuracy). This court in Holleman also considered the results of annual
    recertifications that occurred between the dog-and-handler team’s initial certification
    and the search at issue. K9 Castor and Trooper Mlynar have similarly been recertified
    annually, which further supports a finding of K9 Castor’s reliability.
    Perez also argues that Trooper Mlynar impermissibly cued K9 Castor to lay
    down by tapping the passenger side of the Impala. Trooper Stern testified that tapping
    on a car is “just a way of guiding the dog to where they want that dog to search” as
    part of the systematic, detailed search portion of a sniff. R. Doc. 196, at 74. We are
    not convinced that K9 Castor was impermissibly cued before alerting and prompting
    the search at issue. Further, Trooper Mlynar’s suspicions about Perez that developed
    before K9 Castor’s sniff contributed to the circumstances which, viewed through the
    lens of common sense, would lead a reasonable person to believe that a search would
    reveal contraband or evidence of a crime. See Holleman, 743 F.3d at 1158; Harris,
    56 U.S. at 248.

    4. State Court Search Warrants
    Perez argues that the state court search warrants were improperly issued under
    Franks v. Delaware, 
    438 U.S. 154
     (1978), because they contained material omissions
    and because the evidence supporting the warrants were the fruits of an
    unconstitutional search and seizure.
    To prevail on a Franks claim the defendant[] must show: . . . . (1) that
    facts were omitted with the intent to make, or in reckless disregard of
    whether they make, the affidavit misleading; and (2) that the affidavit,
    if supplemented by the omitted information, could not support a finding
    of probable cause.
    United States v. Reinholz, 
    245 F.3d 765
    , 774 (8th Cir. 2001).
    In determining if an affiant’s statements were made with reckless disregard for
    the truth, the test is whether, after viewing all the evidence, the affiant must
    have entertained serious doubts as to the truth of his statements or had obvious
    reasons to doubt the accuracy of the information he reported.
    United States v. McIntyre, 
    646 F.3d 1107
    , 1114 (8th Cir. 2011) (internal quotation
    marks omitted). “Recklessness, however, may be ‘inferred from the fact of omission
    of information from an affidavit . . . when the material omitted would have been
    ‘clearly critical’ to the finding of probable cause.’” 
    Id.
     (alteration in original) (quoting
    United States v. Mashek, 
    606 F.3d 922
    , 928 (8th Cir. 2010)).
    Perez argues that the warrant applications contained material omissions
    because Trooper Mlynar did not include “information regarding K9 Castor’s
    reliability and his compliance with impound procedures.” Appellant’s Br. at 34. As
    to the first prong of the inquiry, “[t]here is no evidence that [Trooper Mlynar] omitted
    the facts with the intent to make, or in reckless disregard of whether the omissions
    made, the affidavit misleading.” United States v. Wilson, 324 F. App’x 546, 548 (8th
    -16-
    Cir. 2009) (unpublished per curiam). And as to the second prong of the inquiry, even
    if Trooper Mlynar intentionally or recklessly omitted information about K9 Castor’s
    reliability, Perez cannot show that an affidavit that includes that information could
    not support a finding of probable cause. We have found that K9 Castor’s sniff was
    reliable and that the search conducted as a result of her sniff was supported by
    probable cause. See supra Part III.A.3. For that reason, the items found during that
    search are therefore not fruits of an unconstitutional search.
    We have also concluded that Trooper Mlynar complied with NDHP’s impound
    procedures. See supra Part III.A.2. The items found during the search of the Impala
    after impoundment are not fruits of an unconstitutional seizure.
    Perez’s arguments focus on Trooper Mlynar’s omissions in his warrant
    applications, but a North Dakota Bureau of Criminal Investigation Agent applied for
    the warrants for the electronic devices found in the Impala; furthermore, a Bureau of
    Indian Affairs Division of Drug Enforcement Special Agent applied for the warrants
    for the social media accounts. To the extent that Perez argues that those warrant
    applications were deficient in the same ways as the warrant application filed by
    Trooper Mlynar, we reject his arguments for the same reasons.
    B. Motion for a Mistrial
    Perez argues that the government’s comment during its closing
    statement—“Remember the evidence is clear and it’s uncontroverted. [Perez] and [his
    passengers in the Impala] had come to Spirit Lake to sell meth,” R. Doc. 305, at
    23—violated his right not to testify because he is the only person who could have
    rebutted that statement. Appellant’s Br. at 38–39 (citing United States v. Snook, 
    366 F.3d 439
    , 444 (7th Cir. 2004) (“Comments that government evidence is unrebutted
    are improper only if the defendant was the only person who could have rebutted the
    evidence.”)).
    -17-
    “It is well established that ‘the Fifth Amendment . . . forbids either comment
    by the prosecution on the accused’s silence or instructions by the court that such
    silence is evidence of guilt.’” United States v. Gardner, 
    396 F.3d 987
    , 988 (8th Cir.
    2005) (alteration in original) (quoting Griffin, 
    380 U.S. at 615
    ). We “review[] de novo
    whether the prosecutor has unconstitutionally commented on the defendant’s failure
    to testify.” 
    Id.
     “When the prosecutor has neither directly commented on the
    defendant’s silence, nor demonstrated an intent to draw attention to that silence, the
    issue is whether ‘the jury would naturally and necessarily understand the comments
    as highlighting the defendant’s failure to testify.’” Id. at 989 (quoting Herrin v.
    United States, 
    349 F.3d 544
    , 546 (8th Cir. 2003)). We evaluate the prosecutor’s
    comments “in the context of the entire closing arguments and the evidence introduced
    at trial.” 
    Id.
    Taking into account the context of the government’s entire closing argument
    and the evidence presented throughout the trial, a jury would not have naturally and
    necessarily taken the government’s remark as a comment on Perez’s failure to testify.
    Prior to making the remark at issue, the government had summarized the types of
    firearms that were involved in the commission of the instant drug trafficking offenses
    and explained that the firearms were used in furtherance of those crimes. After
    making the remark, the government argued that Perez actually or constructively
    possessed those firearms and explained how he used them in the scheme with his
    passengers. Additionally, trial evidence included 1.5 pounds of methamphetamine,
    three firearms, and the corroborating testimonies of Perez’s passengers.
    A prosecutor may mention the absence of evidence contrary to guilt without
    commenting on the defendant’s decision not to testify when the statements “were
    simply in reference to the strength and clarity of the government’s evidence presented
    at trial.” United States v. Moore, 
    129 F.3d 989
    , 993 (8th Cir. 1997), as amended on
    denial of reh’g and reh’g en banc (Dec. 16, 1997); see also United States v. Emmert,
    
    9 F.3d 699
    , 702–03 (8th Cir. 1993) (explaining that comments that “‘there is no
    -18-
    evidence,’ ‘no testimony,’ [and] ‘no explanation’” did not manifest an intention by
    the government to call attention to the defendant’s failure to testify).
    “A defendant must establish that ‘a prosecutor’s comment was both improper
    and prejudicial to the defendant’s substantial rights’ to obtain a new trial.” United
    States v. Sandstrom, 
    594 F.3d 634
    , 661–62 (8th Cir. 2010) (quoting Gardner, 
    396 F.3d at 988
    ). Not only was the government’s comment not improper, but Perez also
    did not demonstrate that he suffered any prejudice from the government’s remark.
    The district court instructed the jury as to the burden of proof and Perez’s right not
    to testify. See United States v. Patterson, 
    684 F.3d 794
    , 798 (8th Cir. 2012) (“Any
    prejudice caused by the prosecutor’s isolated comment was sufficiently cured by the
    district court’s immediate statement to the jury and its final jury instructions.”). Perez
    also addressed the burden of proof in his own closing argument. And the government
    suggested a curative instruction, which Perez declined.
    Because Perez neither established that the government’s comment was
    improper nor that he was prejudiced by the comment, we affirm the district court’s
    denial of his motion for a mistrial.
    IV. Conclusion
    Accordingly, we affirm the judgment of the district court.
