    JUDGE RYAN M. HARRIS authored this Opinion, in which
    JUDGE KATE APPLEBY concurred. JUDGE JILL M. POHLMAN
    concurred in part and dissented in part, with opinion.
    HARRIS, Judge:
    ¶1      After searching the prison cell Darrin James Gallegos
    shared with a cellmate (Cellmate), guards found a shank hidden
    in a shoe. At first, Gallegos and Cellmate agreed that the shank
    belonged to Gallegos. But a few months later, after criminal
    charges were filed against Gallegos, they changed their stories
    and insisted the shank belonged to Cellmate. A jury later
    convicted Gallegos of possession of a dangerous weapon by a
    restricted person, a first-degree felony. Gallegos now appeals
    that conviction, and challenges the trial court’s admission of
    three pieces of evidence: Gallegos’s previous possession of a
    similar shank, Gallegos’s and Cellmate’s affiliation in gangs, and
    State v. Gallegos
    Gallegos’s and Cellmate’s sentences and parole statuses. Under
    the circumstances, the trial court did not abuse its discretion by
    admitting the gang evidence or evidence about their sentences
    and parole statuses at the time the shank was discovered. But
    evidence about the potential sentence Gallegos faced if convicted
    at trial should not have been admitted and, most significantly,
    we conclude that the trial court improperly allowed the jury to
    learn that Gallegos had previously possessed a similar shank.
    And we are persuaded that admission of the previous shank
    evidence, in particular, was not harmless. Accordingly, we
    reverse Gallegos’s conviction and remand for a new trial.
    BACKGROUND
    ¶2     Gallegos is an inmate at the Utah State Prison, and for a
    time he shared a cell with Cellmate. One day, prison officials
    were searching prisoners’ cells for contraband. While searching
    the cell shared by Gallegos and Cellmate, officers discovered a
    “homemade weapon,” or “shank,” located in an Adidas brand
    shoe. The shoe was located in a common area of the cell, on the
    floor between the two bunks and the toilet. The weapon was a
    nine-inch “piece of steel” cut from the frame of a bunk bed and
    “sharpened . . . into a point” on one end.
    ¶3     After finding the shank, officers asked Gallegos and
    Cellmate “if either one of them wanted to claim ownership,” and
    both initially denied knowing anything about it. Later that day,
    however, Gallegos admitted to one officer that the shank was
    his, and a few weeks later made the same admission to a
    different officer during a follow-up interview. The prison held
    separate internal disciplinary hearings about the incident for
    both Gallegos and Cellmate, and each of them stated, at their
    hearings, that the shank belonged to Gallegos, and that he would
    “accept accountability” for it. As a result, prison officials
    dismissed all internal disciplinary charges against Cellmate.
    20190029-CA                     2              
    2020 UT App 162
    State v. Gallegos
    ¶4      The State then filed a criminal charge against Gallegos,
    accusing him of one first-degree-felony count of possession of a
    dangerous weapon by a restricted person. 1 After that criminal
    charge was filed, Gallegos and Cellmate each changed their
    stories, and claimed that the shank had actually belonged to
    Cellmate, not to Gallegos. In recorded phone calls made from
    prison, Gallegos explained to a listener that he had originally
    claimed ownership of the shank because the likely internal
    prison punishment would be a fine, which did not matter to
    Gallegos because his prison account (referred to as his “books”)
    was already so burdened with other fines and restitution that he
    had stopped using it. Cellmate’s books, on the other hand, were
    clear, and Cellmate had been allowing Gallegos to use his prison
    account for deposits and purchases. If Cellmate were to be fined,
    it would have made using his prison account much more
    difficult for each of them. Moreover, Cellmate also testified that,
    at the time, he had just received his “level three” eligibility to be
    moved from the maximum-security section of the prison to
    general “population,” and if the shank were determined to be
    his, he would have had to remain in maximum security.
    1. Under Utah law, possession of a weapon by a restricted
    person is a crime that can be charged as anything from a class A
    misdemeanor up to a first-degree felony, depending on the type
    of weapon involved and on various other factors, including the
    defendant’s criminal history. Gallegos is a “Category I restricted
    person” because of his criminal history, and was charged under
    a statute mandating that the crime of which he was accused was
    a “third-degree felony.” See 
    Utah Code Ann. § 76-10-503
    (2)(b)
    (LexisNexis 2017). However, the State also alleged that Gallegos
    was a “habitual violent offender,” a status that raises the penalty
    for a third-degree felony to that of a first-degree felony. See 
    id.
    § 76-3-203.5(2)(a). On appeal, Gallegos does not take issue with
    the State’s position regarding the severity of the charged offense.

    2020 UT App 162
    State v. Gallegos
    ¶5      As the case proceeded toward trial, the State made
    motions asking the trial court to admit three types of evidence.
    First, the State wanted to introduce evidence that, over four
    years earlier, Gallegos had been found to be in possession of a
    similar shank, also cut from the frame of a bunk bed—evidence
    the State considered relevant to the question of who possessed
    the shank on this occasion. Second, the State sought permission
    to inform the jury that Gallegos and Cellmate were members of
    affiliated gangs, and would therefore be more likely to protect
    each other. Third, the State intended to introduce evidence that
    Cellmate was in prison for murder and was serving a sentence of
    life without the possibility of parole (LWOP), while Gallegos, by
    contrast, was not only eligible for parole but, at the time the
    shank was discovered, had a parole hearing coming up. The
    State asserted that these last two categories of evidence were
    relevant to show why Gallegos and Cellmate would have
    changed their stories about ownership of the shank. Gallegos
    opposed the motions, asserting that the evidence about his
    previous shank possession was improper under rule 404(b) of
    the Utah Rules of Evidence, and that all of the evidence was
    unduly prejudicial under rule 403.
    ¶6     After briefing and argument, the trial court granted the
    State’s motions, and allowed the State to introduce all three
    types of evidence. The court offered to give a limiting instruction
    regarding the gang evidence and the parole status evidence, but
    Gallegos declined that offer. Gallegos did seek, and the court
    gave, a limiting instruction regarding Gallegos’s possession of a
    shank on a previous occasion, instructing the jury that it could
    consider Gallegos’s possession of a previous shank,
    if at all, for the limited purpose of: [considering]
    [w]hether there was a sufficient nexus
    (relationship) between [Gallegos] and the weapon
    . . . for you to determine that [Gallegos] had both
    the power and intent to exercise dominion and
    20190029-CA                     4               
    2020 UT App 162
    State v. Gallegos
    control over any allegedly dangerous weapon in
    this case. This evidence is not admitted to prove a
    character trait of [Gallegos] or to show that he
    acted in a manner consistent with such a trait. Keep
    in mind that [Gallegos] is on trial for the crimes
    charged in this case, and for those crimes only. You
    may not convict a person simply because you
    believe [he] may have committed some other acts
    at another time.
    ¶7      At trial, the State called several witnesses during its case-
    in-chief, all of whom were officers or investigators affiliated with
    the prison. The officers who found the shank in the shoe
    testified, as did a different officer who found a similar shank in
    Gallegos’s possession more than four years earlier. The State also
    called a prison investigator who specializes in gangs, who
    testified about the specific affiliated gangs to which Gallegos and
    Cellmate belonged, and that members of these gangs have a
    duty to “have some sort of weapon” and to be ready to defend
    other gang members. The investigator also testified that fellow
    gang members sometimes agree to take charges for one another,
    particularly where a charge would mean a harsher sentence for
    one gang member as opposed to another. In connection with this
    testimony, the State introduced evidence of Gallegos’s and
    Cellmate’s tattoos to establish their gang affiliations.
    ¶8     A different prison investigator testified about recorded
    phone calls Gallegos made from the prison, as well as about
    Gallegos’s and Cellmate’s prison accounts and parole statuses.
    With regard to parole status, the investigator testified that
    Cellmate was serving a LWOP sentence and had no possibility of
    being paroled, but that Gallegos, by contrast, was eligible for
    parole and “in theory” could be paroled at any time. Indeed, the
    investigator noted that, at one point, Gallegos had a parole
    hearing scheduled for a date ten months after the shank was
    discovered, and that his parole status could “depend in part on
    20190029-CA                      5               
    2020 UT App 162
    State v. Gallegos
    his conduct while in prison.” In connection with this evidence,
    the jury heard Gallegos (on a recorded phone call) mention that
    he was facing “five-to-life” in this case. Although the State made
    no further mention of the potential sentence Gallegos might
    receive if convicted, Gallegos’s attorney mentioned the issue in
    cross-examination and in closing argument, implying that five
    years to life was an overly long and unjust sentence for being
    caught with a shank in a shoe.
    ¶9     Gallegos elected not to testify, but he called Cellmate,
    who testified that both the Adidas shoes and the shank were his,
    and did not belong to Gallegos; he even described in some detail
    the manner in which he had cut the shank from the bed frame.
    Cellmate also testified that, like Gallegos, he had been caught
    with a shank on one previous occasion, before he shared a cell
    with Gallegos; in his case, the previous episode occurred about a
    year before the shank was discovered in their shared cell.
    ¶10 After deliberation, the jury convicted Gallegos of
    possessing the shank. Outside the presence of the jury, the trial
    court found that Gallegos was a restricted person and a habitual
    violent offender, and that Gallegos therefore was guilty of a first-
    degree felony. The court later sentenced Gallegos to prison for
    five years to life, to run consecutive to the sentence he was
    already serving.
    ISSUE AND STANDARD OF REVIEW
    ¶11 Gallegos appeals, challenging the trial court’s admission
    of the three types of evidence discussed above. We review for
    abuse of discretion the court’s decision to admit this evidence.
    See Met v. State, 
    2016 UT 51
    , ¶ 96, 
    388 P.3d 447
     (stating that a trial
    court’s decision to admit evidence pursuant to rule 403 is
    reviewed for abuse of discretion, which occurs when the court
    “applies the wrong legal standard or its decision is beyond the
    limits of reasonability” (quotation simplified)); see also State v.
    20190029-CA                      6

    2005 UT 11
    , ¶ 15, 
    108 P.3d 730
     (“When examining a [trial]
    court’s decision to admit evidence under Utah Rule of Evidence
    404(b), we review for an abuse of discretion.”).
    ANALYSIS
    I
    ¶12 Gallegos first challenges the trial court’s decision to allow
    the State to introduce evidence that, on a prior occasion some
    four years before the incident in question, Gallegos possessed a
    similar prison shank, also cut from a bedframe.
    ¶13 Rule 404(b)(1) of the Utah Rules of Evidence prohibits the
    introduction of evidence “of a crime, wrong, or other act . . . to
    prove a person’s character in order to show that on a particular
    occasion the person acted in conformity with the character.”
    Accord State v. Lopez, 
    2018 UT 5
    , ¶ 38, 
    417 P.3d 116
    . This
    subsection of the rule “recognizes the dangers of exposing a jury
    to evidence of a defendant’s acts of prior misconduct—
    specifically, the risk that the jury will infer that the defendant
    has a reprehensible character, that he probably acted in
    conformity with it, and that he should be punished for his
    immoral character in any event.” State v. Thornton, 
    2017 UT 9
    ,
    ¶ 35, 
    391 P.3d 1016
     (quotation simplified). This forbidden line of
    thinking is sometimes referred to as a “propensity inference”—
    that is, if jurors are told that a person has acted in a certain way
    on previous occasions, they may conclude that it is in that
    person’s character to act that way, and may conclude that, due to
    this propensity, the person was much more likely to have acted
    in conformity with that propensity on the occasion in question.
    See, e.g., State v. Lucero, 
    2014 UT 15
    , ¶ 14, 
    328 P.3d 841
     (referring
    to the “propensity inference” (quotation simplified)), abrogated
    on other grounds by State v. Thornton, 
    2017 UT 9
    , 
    391 P.3d 1016
    ;
    accord State v. Verde, 
    2012 UT 60
    , ¶ 39, 
    296 P.3d 673
    , abrogated on
    20190029-CA                      7               
    2020 UT App 162
    State v. Gallegos
    other grounds by State v. Thornton, 
    2017 UT 9
    , 
    391 P.3d 1016
    . Our
    supreme court has referred to the propensity inference as
    “improper,” Lucero, 
    2014 UT 15
    , ¶ 14, and “impermissible,”
    Verde, 
    2012 UT 60
    , ¶ 39; see also id. ¶ 15 (stating that, when prior
    acts evidence “is offered to suggest action in conformity with a
    person’s alleged bad character, it is inadmissible”).
    ¶14 But while evidence of a defendant’s other bad acts is not
    admissible under rule 404(b) to prove propensity, that rule
    allows admission of evidence of such acts for other purposes.
    The rule provides that such evidence “may be admissible for
    another purpose, such as proving motive, opportunity, intent,
    preparation, plan, knowledge, identity, absence of mistake, or
    lack of accident.” See Utah R. Evid. 404(b)(2). Thus, “when past
    misconduct evidence is offered for any other purpose—other
    than to suggest action in conformity with the bad character
    suggested by [a defendant’s] prior bad acts—such evidence is
    admissible so long as it satisfies rules 402 and 403.” See Thornton,
    
    2017 UT 9
    , ¶ 36 (quotation simplified).
    ¶15 Our supreme court has distilled these principles into a
    three-part test that governs admissibility of other-bad-acts
    evidence pursuant to rule 404(b)(2). “Such evidence is admissible
    if it (1) is relevant to, (2) a proper, non-character purpose, and (3)
    does not pose a danger for unfair prejudice that substantially
    outweighs its probative value.” State v. Killpack, 
    2008 UT 49
    , ¶ 45,
    
    191 P.3d 17
     (quotation simplified); see also Lucero, 
    2014 UT 15
    ,
    ¶ 37 (instructing “trial courts to engage in a three-part analysis
    under rules 404(b), 402, and 403”).
    ¶16 The first step in this analysis requires that the evidence be
    relevant, as that term is used in rules 401 and 402. But this test
    presents “a low bar,” see Thornton, 
    2017 UT 9
    , ¶ 61, because
    “[e]vidence is relevant if . . . it has any tendency to make a fact
    [of consequence] more or less probable than it would be without
    the evidence,” Utah R. Evid. 401. On appeal, Gallegos does not
    20190029-CA                      8                
    2020 UT App 162
    State v. Gallegos
    contend that the court abused its discretion by determining that
    the evidence regarding the previous shank was relevant.
    ¶17 Gallegos does, however, challenge the trial court’s
    conclusions that the remaining two parts of the test were met
    here. First, he challenges the court’s determination that the
    previous shank evidence was admitted for a proper, non-
    propensity purpose. Second, he challenges the court’s rule 403
    determination that the probative value of the previous shank
    evidence was not substantially outweighed by the risk of unfair
    prejudice. In summary, Gallegos asserts that both rule 404(b) and
    rule 403 require exclusion of this evidence. We discuss the
    applicability of each rule, in turn, and conclude that, even if the
    court’s admission of the evidence did not violate rule 404(b), it
    did violate rule 403.
    A
    ¶18 Under the second step of the test, the proponent of the
    prior acts evidence must demonstrate that the evidence is being
    admitted for a proper, non-propensity purpose. Here, the State
    asserts that the prior shank evidence is relevant to link Gallegos
    to the present shank, and helps demonstrate that he at least
    constructively possessed it. 2 As the State puts it, “[a]t issue here
    is the relevance of prior possession to show current possession.”
    2. “Constructive possession is a legal fiction whereby a person is
    deemed to possess contraband even when he [or she] does not
    actually have immediate physical control of the object.” See
    United States v. Schmitt, 
    770 F.3d 524
    , 534 (7th Cir. 2014)
    (quotation simplified); see also Constructive Possession, Black’s
    Law Dictionary (11th ed. 2019) (defining “constructive
    possession” as “[c]ontrol or dominion over a property without
    actual possession or custody of it”).
    20190029-CA                      9               
    2020 UT App 162
    State v. Gallegos
    ¶19 To prove that Gallegos at least constructively possessed
    the shank, the State must “prove that there was a sufficient
    nexus between the accused and the [contraband] to permit an
    inference that the accused had both the power and the intent to
    exercise dominion and control over” the contraband. See State v.
    Workman, 
    2005 UT 66
    , ¶ 31, 
    122 P.3d 639
     (quotation simplified).
    Whether a “sufficient nexus” exists “depends upon the facts and
    circumstances of each case.” 
    Id.
     (quotation simplified); see also
    State v. Fox, 
    709 P.2d 316
    , 319 (Utah 1985) (stating that “the
    determination that someone has constructive possession of
    drugs is a factual determination which turns on the particular
    circumstances of the case”). And our supreme court, in a series
    of drug cases, has identified “[s]everal factors [that] may be
    important” in evaluating constructive possession, including the
    following: (a) ownership or occupancy of the residence or
    vehicle where the drugs were found; (b) the presence of the
    defendant at the time the drugs were found; (c) the defendant’s
    proximity to the drugs; (d) “previous drug use”; (e) whether the
    defendant made incriminating statements or exhibited
    incriminating behavior; and (f) the presence of drugs in a specific
    area where the defendant had control. See Workman, 
    2005 UT 66
    ,
    ¶ 32; see also Fox, 709 P.2d at 319 (listing factors); State v.
    Anderton, 
    668 P.2d 1258
    , 1264 (Utah 1983) (Durham, J.,
    concurring majority) (same). But the court has also cautioned
    against rigid reliance on a list of factors in evaluating
    constructive possession, since such factors are “particularly
    relevant to the specific factual context in which those cases
    arose,” and are not necessarily “universally pertinent factors,”
    nor are they “legal elements of constructive possession in any
    context.” See State v. Layman, 
    1999 UT 79
    , ¶ 14, 
    985 P.2d 911
    .
    ¶20 Our supreme court has applied this test rather narrowly.
    In particular, there are several things relevant here that our
    supreme court has never done. First, in discussing the “previous
    drug use” factor in its constructive possession test, our supreme
    court has never analyzed the propensity implication that factor
    20190029-CA                    10               
    2020 UT App 162
    State v. Gallegos
    seems to invite. Second, that court has never phrased the
    “previous use” factor in terms of “previous possession”; rather,
    it has always spoken in terms of “use.” See Workman, 
    2005 UT 66
    ,
    ¶ 32 (stating that “previous drug use” was a factor that could be
    considered); Anderton, 668 P.2d at 1264. Indeed, in Anderton, the
    relevance of the use factor was limited to “use and enjoyment”
    of the drugs in question in the case, and not prior use of other
    drugs. See 668 P.2d at 1264 (listing the defendant’s
    “participati[on] with others in the mutual use and enjoyment of
    the contraband” as a factor that could be considered (quotation
    simplified)). And third, the parties direct our attention to no case
    in which our supreme court has applied these factors generally,
    or the “previous use” factor specifically, to establish constructive
    possession in any non-drug case. As Gallegos points out, there
    may be reasons why one might consider previous use more
    relevant to constructive possession—and perhaps somewhat less
    related to a forbidden propensity inference—in drug cases than
    in other types of cases.
    ¶21 But unlike our supreme court, we have extended the
    previous use concept to non-drug cases, and—also without
    analyzing the applicability of rule 404(b)—we have even stated
    that “previous possession of similar contraband by the
    defendant” is relevant to show that the defendant had at least
    constructive possession of contraband in the later incident. See
    State v. Lucero, 
    2015 UT App 120
    , ¶ 7, 
    350 P.3d 237
     (case
    involving drugs and weapons); see also State v. Clark, 
    2015 UT App 289
    , ¶ 20, 
    363 P.3d 544
     (stating in a case involving stolen
    identification that “previous possession of similar contraband” is
    a “factor that may support a finding of constructive possession”
    (quotation simplified)). And some federal cases, applying the
    federal version of rule 404(b), have employed similar analyses in
    cases involving illegal possession of firearms. See, e.g., United
    States v. Moran, 
    503 F.3d 1135
    , 1144 (10th Cir. 2007) (holding that
    evidence that the defendant previously possessed a similar
    firearm was “probative to demonstrate that [he] knowingly
    20190029-CA                     11               
    2020 UT App 162
    State v. Gallegos
    possessed the firearm” in question (quotation simplified));
    United States v. Cassell, 
    292 F.3d 788
    , 793 (D.C. Cir. 2002) (stating
    that “where a defendant is charged with unlawful possession of
    something, evidence that he possessed the same or similar things
    at other times is often quite relevant to his knowledge and intent
    with regard to the crime charged” (quotation simplified)).
    ¶22 While we can certainly appreciate that a defendant’s prior
    possession of a firearm is relevant to demonstrating that he
    constructively possessed a similar firearm on a later occasion, it
    appears to us that the main reason such evidence is relevant for
    that purpose is that it demonstrates propensity—that the
    defendant’s previous possession of weapons may indicate a
    propensity to possess weapons, and may indicate that the
    defendant acted in conformity with that propensity and
    possessed another weapon on a later occasion. There is no
    question that propensity evidence has relevance. See State v.
    Murphy, 
    2019 UT App 64
    , ¶ 47, 
    441 P.3d 787
     (Harris, J.,
    concurring) (stating that propensity evidence “is excluded not
    because it has no probative value but because it has too much”
    (quotation simplified)). But “[f]idelity to the integrity of the rule
    requires a careful evaluation of the true—and predominant—
    purpose of any evidence proffered under rule 404(b).” See Verde,
    
    2012 UT 60
    , ¶ 22. And after reviewing the parties’ briefs and
    relevant case law, we find it difficult to discern a separate non-
    propensity reason why evidence that Gallegos previously
    possessed a similar shank makes it more likely that he
    constructively possessed a shank on a later occasion.
    ¶23 In an attempt to demonstrate a proper non-propensity
    purpose, the State asserts that Gallegos’s previous possession of
    a similar shank was relevant to show his “knowledge of” and his
    “motive and intent to possess” the second shank. Thus, the State
    invokes three of the reasons listed in rule 404(b)(2) as potentially
    valid non-propensity purposes for admission of prior acts
    evidence: knowledge, motive, and intent. In addition, the State
    20190029-CA                     12               
    2020 UT App 162
    State v. Gallegos
    phrased its argument differently—and more philosophically—at
    oral argument, asserting that the prior acts evidence was not
    character evidence at all, because it was not intended to say
    anything about who Gallegos was as a person, but instead was
    intended merely to inform the jury of certain acts he had
    committed. We discuss each of these arguments, in turn.
    1
    ¶24 To be sure, “knowledge” can be a proper non-character
    purpose under rule 404(b). Not only is knowledge identified in
    the text of the rule as one of the enumerated permissible
    purposes, see Utah R. Evid. 404(b)(2), we have also previously
    held that, in appropriate cases, prior bad acts evidence can come
    in to prove a defendant’s knowledge in the case at hand, see, e.g.,
    State v. McDonald, 
    2005 UT App 86
    , ¶ 12, 
    110 P.3d 149
    . But it is
    insufficient for the proponent of prior bad acts evidence merely
    to incant the word “knowledge”; instead, in order to analyze
    whether knowledge is a proper non-character purpose, rather
    than just shorthand for a propensity inference, we must know
    more about what type of knowledge the evidence tends to show
    in a particular case.
    ¶25 In some cases, evidence of prior bad acts can help
    demonstrate that a defendant has the requisite state of mind for
    conviction—that he knew that his actions were unlawful or
    likely to result in injury. In McDonald, for instance, the defendant
    was accused of cruelty to animals, a charge resulting from the
    defendant keeping fifty-eight cats in an unventilated, enclosed
    trailer. 
    2005 UT App 86
    , ¶¶ 2–6. In order to convict the
    defendant, the State was required to prove that she acted
    “intentionally, knowingly, recklessly, or with criminal
    negligence.” See 
    Utah Code Ann. § 76-9-301
    (2) (2003). To prove
    the defendant’s state of mind, the State presented evidence that
    she had, on a previous occasion, possessed some fifty cats, and
    that she had been warned by animal control officers at the time
    20190029-CA                     13               
    2020 UT App 162
    State v. Gallegos
    that “keeping multiple cats in a confined area for too long a time
    could cause sickness or injury to the cats.” McDonald, 
    2005 UT App 86
    , ¶ 11. We held that the court did not abuse its discretion
    by admitting the prior acts evidence, because it helped “establish
    [the defendant’s] knowledge that her conduct was likely to
    result in sickness or injury to the cats that she was confining,”
    and therefore the evidence went “directly towards proving [the
    defendant’s] state of mind” in confining the cats. Id. ¶ 12. Thus,
    the prior acts evidence was used primarily to demonstrate the
    defendant’s knowledge that her actions were likely to result in
    injury to the animals, rather than to show that she was the type
    of person who would act cruelly toward animals. Id.; see also
    State v. Rackham, 
    2016 UT App 167
    , ¶ 17, 
    381 P.3d 1161
     (evidence
    of the defendant’s “previous experience with his young cousins
    and nieces becoming alarmed or affronted by his unwanted
    touching” was relevant to demonstrate the defendant’s
    knowledge that such touching would be unwelcome).
    ¶26 In other cases, where a defendant contends that he could
    not have committed the crime because he does not possess
    certain knowledge necessary to its commission, some courts
    have concluded that evidence of prior bad acts can be admitted
    to refute that contention. See, e.g., United States v. Miller, 
    673 F.3d 688
    , 698 (7th Cir. 2012) (stating that evidence of prior cocaine
    possession might be relevant to prove knowledge in a case
    where the defendant asserted that “he lacked knowledge of
    cocaine or how to sell it”); United States v. Mendoza, 
    341 F.3d 687
    ,
    692 (8th Cir. 2003) (holding that, where the defendant argued
    that “he was just along for the ride and did not even know how
    much an ounce of methamphetamine was,” evidence of his prior
    conviction for methamphetamine possession was admissible).
    But see Dean v. State, 
    865 P.2d 601
    , 608 (Wyo. 1993) (stating that
    “knowledge of how to commit the crime is not the knowledge
    Rule 404(b) permits the admission of prior bad acts to prove”),
    abrogated on other grounds as recognized by Williams v. State, 
    99 P.3d 432
     (Wyo. 2004). As applied to this situation, had Gallegos
    20190029-CA                      14                
    2020 UT App 162
    State v. Gallegos
    defended the case by asserting that he did not know how to cut a
    shank from a bed frame and therefore the shank could not have
    been his, evidence of his prior shank possession arguably would
    have been relevant for a non-propensity knowledge-based
    purpose: to rebut the contention that Gallegos did not know how
    to make a shank from a bed frame.
    ¶27 In this case, however, the State does not claim to have
    offered the prior bad acts evidence to demonstrate either of these
    types of knowledge. Gallegos did not defend the case by
    asserting that he lacked knowledge about how to make a shank,
    and Gallegos’s state of mind (that is, whether he acted with
    intent, knowledge, recklessness, or negligence) was never the
    issue. Instead, the State asserts that the prior bad acts evidence is
    relevant to the constructive possession issue because it tends to
    show that Gallegos had “knowledge of . . . the shank” on this
    occasion. But under these circumstances, given Gallegos’s
    defenses and the relevant issues at trial, we fail to see how
    Gallegos’s possession of a shank on a previous occasion helps
    demonstrate Gallegos’s “knowledge of” the shank in question,
    other than through a propensity inference. 3 See Verde, 
    2012 UT 3
    . One federal court examining this issue in a similar case
    acknowledged that admitting evidence of a prior instance of
    weapons possession “to prove knowledge” for constructive
    possession purposes on a later occasion “involves a kind of
    propensity inference (i.e., because [the defendant] knowingly
    possessed a firearm in the past, he knowingly possessed the
    firearm in the present case).” See United States v. Moran, 
    503 F.3d 1135
    , 1145 (10th Cir. 2007). In that case, the court admitted the
    evidence nonetheless, but did so using a probability theory
    similar to the doctrine of chances. See 
    id.
     (stating that the prior
    acts evidence could be admitted for the purposes of supporting
    an inference resting “on a logic of improbability that recognizes
    that a prior act involving the same knowledge decreases the
    (continued…)
    20190029-CA                     15               
    2020 UT App 162
    State v. Gallegos
    60, ¶ 26 (“In context, it seems much more likely that [the
    evidence] was aimed at sustaining an impermissible inference
    that [the defendant] acted in conformity with the bad character
    suggested by his prior bad acts.”). We are therefore unconvinced
    that “knowledge” can supply a proper non-character purpose
    for admission of the prior bad acts evidence under the
    circumstances presented here.
    2
    ¶28 In addition to knowledge, the State also argued that
    evidence of Gallegos’s prior shank possession should be
    admissible to show his “motive” to possess the current shank.
    Motive is one of the reasons listed in rule 404(b)(2) that might
    serve to justify admission of prior bad acts evidence, see Utah R.
    Evid. 404(b)(2), and we have recognized its applicability in some
    cases, see State v. Losee, 
    2012 UT App 213
    , ¶¶ 18–19, 
    283 P.3d 1055
    (affirming the admission of evidence of a previous assault,
    because it explained why the defendant might have had a
    motive to solicit the murder of the victim of the original assault).
    (…continued)
    likelihood that the defendant lacked the requisite knowledge in
    committing the charged offense”); see also State v. Verde, 
    2012 UT 60
    , ¶¶ 47–51, 
    296 P.3d 673
     (describing the doctrine of chances),
    abrogated on other grounds by State v. Thornton, 
    2017 UT 9
    , 
    391 P.3d 1016
    . While the doctrine of chances was among the grounds the
    State invoked when seeking admission of the prior shank
    incident before the trial court, that court made no ruling
    regarding the applicability of the doctrine of chances, and on
    appeal the State does not ask us to affirm the court’s admission
    of the shank evidence pursuant to the doctrine of chances; we
    therefore do not address whether that doctrine might apply here.
    20190029-CA                     16               
    2020 UT App 162
    State v. Gallegos
    ¶29 In this case, however, Gallegos’s motive was never in
    question. Gallegos was a maximum-security prisoner at the Utah
    State Prison, and was a member of a prison gang that demanded
    loyalty of its members, including a duty to “have some sort of
    weapon” and to be ready to defend other gang members.
    Nothing in the record suggests that there was any mystery about
    why Gallegos might have wanted to possess a prison shank, and
    he did not argue he lacked a motive to possess one.
    ¶30 And the State’s reference to “motive” in its briefing is
    fleeting, and unaccompanied by any explanation of how the
    prior acts evidence would have materially added to the jury’s
    perception of what Gallegos’s motive might have been, beyond
    the already-obvious evidence of motive, and other than asking
    the jury to draw a propensity inference. We are therefore
    unpersuaded that “motive” can provide a proper non-character
    purpose for admission of the prior bad acts evidence in this case.
    3
    ¶31 Next, the State asserts that evidence of Gallegos’s prior
    shank possession should be admissible to show his “intent to
    possess the shank discovered in his shared cell.” “Intent” is
    another of the purposes specifically listed in rule 404(b)(2), see
    Utah R. Evid. 404(b)(2), and we have recognized its applicability
    in appropriate cases, see State v. Von Niederhausern, 
    2018 UT App 149
    , ¶ 19, 
    427 P.3d 1277
     (“Evidence is offered for a proper
    noncharacter purpose if used to prove intent.”). Moreover, as the
    State emphasizes, the touchstone of our supreme court’s
    constructive possession test is whether the defendant “had both
    the power and the intent to exercise dominion and control over”
    the contraband. See State v. Workman, 
    2005 UT 66
    , ¶ 31, 
    122 P.3d 639
     (quotation simplified). The State therefore contends that
    evidence of Gallegos’s previous shank possession is admissible
    to show Gallegos’s intent to possess the shank on this occasion.
    20190029-CA                    17              
    2020 UT App 162
    State v. Gallegos
    ¶32 As discussed above, however, Gallegos’s intent—in a
    mens rea 4 sense—was never at issue in the case. Gallegos’s
    defense rested on the assertion that the shank was not his, but
    Cellmate’s; his argument was that he did not possess the shank
    at all, not that he possessed the shank with less-than-criminal
    intent. This is distinct from many other “intent” cases. See, e.g.,
    State v. Widdison, 
    2001 UT 60
    , ¶ 45, 
    28 P.3d 1278
     (affirming the
    admission of previous acts of child abuse to show the “intent
    and mental state” of the defendant when she committed the
    abusive acts of which she was accused); State v. Vu, 
    2017 UT App 179
    , ¶ 19, 
    405 P.3d 879
     (affirming the admission of prior acts of
    methamphetamine sales to demonstrate that the defendant likely
    intended to sell, rather than use himself, the distributable
    amount of methamphetamine with which he was found).
    ¶33 In this case, the only way in which “intent” is relevant is
    as a part of the constructive possession test—whether Gallegos
    had the “intent to exercise dominion and control over” the shank
    in question. See Workman, 
    2005 UT 66
    , ¶ 31 (quotation
    simplified). But in this context, “intent” refers simply to
    possession. The State seeks to admit the evidence to demonstrate
    that, because Gallegos once possessed a shank on a previous
    occasion, it is more likely that he had “intent to” possess one on
    this occasion. But this boils down to nothing more than a
    propensity inference.
    ¶34 Without question, the State had to prove that Gallegos
    constructively possessed the shank, and as part of that inquiry
    had to show that Gallegos had the “intent to exercise dominion
    4. Mens rea is “[t]he state of mind that the prosecution, to secure
    a conviction, must prove that a defendant had when committing
    a crime,” and “is the second of two essential elements of every
    crime at common law, the other being the actus reus.” Mens rea,
    Black’s Law Dictionary (11th ed. 2019).
    20190029-CA                    18               
    2020 UT App 162
    State v. Gallegos
    and control over” it. See 
    id.
     (quotation simplified). But, as our
    supreme court has noted,
    the technical relevance of a defendant’s intent is
    not enough to justify the admissibility of evidence
    of prior bad acts purportedly aimed at establishing
    intent under rule 404(b). Fidelity to the integrity of
    the rule requires a careful evaluation of the true—
    and predominant—purpose of any evidence
    proffered under rule 404(b). Thus, if proof of intent
    is merely a ruse, and the real effect of prior
    misconduct evidence is to suggest a defendant’s
    action in conformity with alleged bad character,
    the ruse is insufficient and the evidence should not
    be admitted.
    Verde, 
    2012 UT 60
    , ¶ 22 (quotation simplified). While the prior
    bad acts evidence here may be technically relevant to show
    intent to possess under Workman, we are unable to discern a non-
    propensity pathway through which that evidence helps prove
    intent to possess. We are thus unpersuaded that “intent”
    provides a proper non-character purpose for admission of
    evidence that Gallegos previously possessed a shank.
    4
    ¶35 Finally, at oral argument before this court, the State took a
    slightly different tack, asserting that, in this context, there is a
    difference between “who a person is” and “what a person did,”
    and that rule 404(b) only bars evidence of the former—that is, it
    bars evidence of a person’s negative character, and does not
    necessarily bar evidence of a person’s prior bad acts insofar as
    that evidence does not bear on the essence of the person’s
    character. Specifically, the State argued that, in this case, the
    evidence of prior shank possession was not intended to show
    that Gallegos was a bad person generally, just that he was a
    person “with a certain level of knowledge or a certain motive,
    20190029-CA                     19               
    2020 UT App 162
    State v. Gallegos
    [and] therefore . . . likely had that motive or that knowledge in
    this instance.” The State argued that the rule excludes propensity
    evidence only when a prosecutor “add[s] an extra step there and
    say[s], ‘somebody did something bad, therefore they are a bad
    person, therefore on this occasion they did something bad.’” In
    essence, “the State’s view is that you can show that somebody
    had intent on a prior occasion and therefore they had intent on
    this occasion without saying anything about who they are.”
    ¶36 We acknowledge the structure of rule 404(b), which
    forbids introduction of “[e]vidence of a crime, wrong or other
    act” for the purpose of proving “a person’s character in order to
    show that on a particular occasion the person acted in
    conformity with that character,” yet allows introduction of prior
    bad acts evidence for other purposes, including “proving
    motive, . . . intent, . . . [or] knowledge.” See Utah R. Evid.
    404(b)(1)–(2). But the term “character,” as used in rule 404(b), is
    broader than the State suggests. The term as used there means
    more than whether the person is, at root, a generally good-
    hearted person with positive qualities; rather, the term is also
    intended to encompass specific traits or propensities the person
    might have, some of which might be negative even if the person
    could be considered generally a good person. Indeed, the rules
    of evidence themselves make clear that there is more than one
    way to prove a person’s “character”: in addition to offering
    evidence of the person’s general reputation in the community, in
    certain instances litigants may prove character by offering
    “relevant specific instances of the person’s conduct.” See Utah R.
    Evid. 405; see also David P. Leonard, The New Wigmore: A Treatise
    on Evidence: Evidence of Other Misconduct and Similar Events § 1.2
    (2009) (stating that character evidence includes “evidence of
    other wrongful acts”). That is, evidence of specific acts, even if
    not presented as evidence of a person’s general character, can
    lead a factfinder to draw inferences about a person’s
    propensities, and therefrom to infer that the person may have
    acted in conformity with those propensities.
    20190029-CA                    20               
    2020 UT App 162
    State v. Gallegos
    ¶37 Our supreme court has noted that the ban on propensity
    evidence is also concerned with evidence of specific behavior,
    and not just evidence of general character, because evidence of
    specific behavior can lead to inferences about broader character
    traits. See, e.g., State v. S.H., 
    2002 UT 118
    , ¶ 24, 
    62 P.3d 444
    (stating that the ban on propensity evidence works “to ensure
    that a defendant is only convicted because he committed the
    charged offense and not because the jury is convinced of his
    cumulative bad behavior” (emphasis added)). Indeed, rule
    404(b)’s restrictions on evidence of prior bad acts are in place
    precisely because of the concern that juries might infer from such
    evidence that a defendant has a negative character trait and
    might have acted in conformity therewith. See State v. Thornton,
    
    2017 UT 9
    , ¶ 35, 
    391 P.3d 1016
     (stating that rule 404(b)
    “recognizes the dangers of exposing a jury to evidence of a
    defendant’s acts of prior misconduct—specifically, the risk that
    the jury will infer that the defendant has a reprehensible
    character [and] that he probably acted in conformity with it”
    (quotation simplified)); Verde, 
    2012 UT 60
    , ¶ 26 (stating that the
    propensity ban is concerned with juries drawing “an
    impermissible inference that [the defendant] acted in conformity
    with the bad character suggested by his prior bad acts”).
    ¶38 Thus, rule 404’s ban on character evidence includes more
    than just a ban on evidence tending to show that a person
    possesses a generally bad character—is a “bad person”—and
    acted in conformity with that bad character; it also includes a
    ban on evidence tending to show that a person—who might
    otherwise be a good person—has a specific negative character
    trait (or propensity) and acted in conformity with that trait.
    Evidence does not have to impugn a person’s entire character in
    order to fall within the ambit of the propensity ban.
    ¶39 Applying these principles to this case, we take the State at
    its word when it asserts that it did not offer the evidence of
    Gallegos’s prior shank possession in an effort to prove that
    20190029-CA                    21              
    2020 UT App 162
    State v. Gallegos
    Gallegos is a bad person. But that evidence surely did raise the
    inference that Gallegos—who might otherwise be a good
    person—might be a person who has a propensity for making
    and keeping prison shanks while incarcerated, and that he might
    have acted in conformity with that propensity in this case. Such
    an inference is forbidden, despite the fact that it may not say
    anything about Gallegos’s character generally.
    ¶40 In the end, we remain unpersuaded that a proper non-
    character purpose existed to support the admission of evidence
    that Gallegos possessed a different shank years earlier. Although
    we acknowledge that, under prior precedent, “previous
    possession of similar contraband by the defendant” is a factor
    that may be considered in evaluating constructive possession, see
    State v. Lucero, 
    2015 UT App 120
    , ¶ 7, 
    350 P.3d 237
    , it is important
    to note that none of our state’s previous constructive possession
    decisions analyzed the rule 404(b) implications of considering
    “previous possession” in connection with constructive
    possession. Because an act of previous possession is a prior bad
    act within the ambit of rule 404(b), we consider it insufficient to
    simply admit evidence of previous possession in this context,
    without examining whether a proper non-character purpose
    exists to support admission of the evidence.
    ¶41 In this case, none of the potential non-character purposes
    proffered by the State seem to fit. All of the proffered purposes—
    knowledge, motive, and intent—seem rooted in a forbidden
    propensity inference: that because Gallegos previously
    possessed a shank, he has a propensity to make and keep
    shanks, and he acted in conformity with that propensity here.
    B
    ¶42 But even if we assume, for the purposes of argument, that
    in our analysis we are missing some subtle distinction between
    the State’s proffered purposes and the forbidden propensity
    inference, in our view any such distinction is likely to be lost on

    2020 UT App 162
    State v. Gallegos
    a lay jury, and therefore the prior bad acts evidence has little
    legitimate probative value, yet comes laden with a substantial
    risk of unfair prejudice. As noted above, the third step in the
    analysis is to apply rule 403 of the Utah Rules of Evidence, and
    assess whether the evidence’s probative value is substantially
    outweighed by the risk of unfair prejudice. See Utah R. Evid. 403;
    see also State v. Killpack, 
    2008 UT 49
    , ¶ 45, 
    191 P.3d 17
     (describing
    the third step in the test as an analysis of whether the evidence
    poses “a danger for unfair prejudice that substantially outweighs
    its probative value” (quotation simplified)). In our view, even if
    there exists a non-propensity purpose served by admission of
    the prior shank evidence in this case, we conclude that the
    legitimate probative value of any such evidence is substantially
    outweighed by the near-certainty that the jury will draw the
    tempting yet forbidden propensity inference.
    ¶43 When conducting a rule 403 balancing test in this context,
    where fear of a forbidden propensity inference is present, courts
    should weigh the evidence’s valid non-character purpose “on
    the probative value side of the ledger,” and should weigh the
    “evidence’s value as propensity evidence . . . on the prejudice
    side of the ledger.” See State v. Fredrick, 
    2019 UT App 152
    , ¶ 45,
    
    450 P.3d 1154
     (quotation simplified); see also United States v.
    Ballou, 
    59 F. Supp. 3d 1038
    , 1069 (D.N.M. 2014) (determining
    that, “[w]ith all rule 404(b) evidence,” courts must undertake a
    rule 403 analysis under which they “weigh the licit, probative
    value of the evidence—meaning the value of the rule 404(b)
    inference—against the danger of unfair prejudice—which
    includes the character-propensity inference”).
    ¶44 In this case, the probative value of the prior acts evidence,
    provided by valid non-propensity purposes, is low. As noted,
    we cannot readily discern a proper non-character purpose for
    the admission of this evidence. Moreover, even if we could
    discern a proper non-character basis to admit this evidence for
    purposes of demonstrating knowledge, motive, or intent, we
    20190029-CA                     23               
    2020 UT App 162
    State v. Gallegos
    would be forced to confront the fact that those issues were not
    actively contested at trial. As noted, Gallegos’s motive to possess
    the shank was obvious, and Gallegos did not argue that he had
    no motive to possess it. And Gallegos’s state of mind, in a mens
    rea sense, was never really at issue; he did not argue that he
    possessed the shank but did so with a non-culpable mental state.
    When intent—or knowledge or motive—is “uncontested and
    readily inferable from other evidence, 404(b) evidence is largely
    tangential and duplicative.” See Verde, 
    2012 UT 60
    , ¶ 26. In such
    situations, the prior bad acts evidence—even if it could be said to
    have a proper non-character purpose—has very little marginal
    probative value. That is the case here.
    ¶45 The risk of unfair prejudice presented by the prior acts
    evidence in this case, by contrast, is high. As we have explained,
    we are having difficulty discerning any proper non-propensity
    purpose for admission of this evidence. And if we are having
    such difficulties, we have no doubt that a lay jury would. The
    trial court’s instruction on this point more or less quoted State v.
    Workman, 
    2005 UT 66
    , 
    122 P.3d 639
    , and stated that the jury
    could consider the prior acts evidence “for the limited purpose
    of” considering “[w]hether there was a sufficient nexus
    (relationship) between [Gallegos] and the weapon for [the jury]
    to determine that [he] had both the power and intent to exercise
    dominion and control” over the shank, but that the evidence was
    “not admitted to prove a character trait . . . or to show that
    [Gallegos] acted in a manner consistent with such a trait.” See id.
    ¶ 31. It is certainly not obvious to us how evidence that a
    defendant possessed a weapon on a previous occasion tightens
    the “nexus” between a defendant and a different weapon found
    on a later occasion, other than through a propensity inference,
    and the court gave no further assistance to the jurors to help
    them understand how—if at all—the permissible purpose was
    different from the impermissible purpose. In light of the nature
    of the evidence and the instruction the jury was given, we
    20190029-CA                     24               
    2020 UT App 162
    State v. Gallegos
    consider it all too likely that the jury would have drawn an
    impermissible propensity inference from this evidence.
    ¶46 Accordingly, we conclude that any valid probative value
    that this evidence may have had was limited and ultimately
    substantially outweighed by the danger of unfair prejudice. We
    think the best way to sum up this situation is by paraphrasing
    our supreme court in Verde:
    [E]ven if the past misconduct evidence in this case
    could plausibly be deemed to have been aimed at a
    legitimate purpose under rule 404(b), it would still
    fail under the balancing framework required under
    rule 403. Specifically, and for all the reasons
    detailed above, we conclude that any legitimate
    tendency the 404(b) evidence had to tell a narrative
    of [Gallegos’s] specific intent [or knowledge or
    motive] was minimal at best. And we likewise
    conclude that any such legitimate purpose is far
    outweighed by the obvious, illegitimate one of
    suggesting action in conformity with bad character.
    See Verde, 
    2012 UT 60
    , ¶ 31. Accordingly, we conclude that the
    trial court exceeded its discretion when it admitted evidence that
    Gallegos possessed a different shank some four years before the
    incident in question.
    II
    ¶47 Gallegos next challenges the trial court’s decision to admit
    evidence that he and Cellmate were members of affiliated gangs,
    specifically taking issue with the admission of photographs of
    their tattoos. Gallegos invokes rule 403 of the Utah Rules of
    Evidence, and asserts that this evidence was unduly prejudicial,
    and that the risk of unfair prejudice substantially outweighed
    the evidence’s probative value. We disagree.
    20190029-CA                    25              
    2020 UT App 162
    State v. Gallegos
    ¶48 Our supreme court has warned trial courts to “view gang-
    related evidence with caution” before admitting it, because such
    evidence often carries with it the risk of “potential prejudice of
    guilt by association.” See State v. Gonzalez, 
    2015 UT 10
    , ¶¶ 37, 40,
    
    345 P.3d 1168
     (quotation simplified); see also State v. High, 
    2012 UT App 180
    , ¶ 26, 
    282 P.3d 1046
     (stating that gang evidence
    should be viewed “with caution due to the risk that it may carry
    some unfair prejudice,” including potentially leading “the jury
    to attach a propensity for committing crimes to defendants who
    are affiliated with gangs or allow its negative feelings towards
    gangs to influence its verdict” (quotation simplified)).
    Nevertheless, gang evidence is often admissible. “In the
    appropriate context, gang evidence has probative value
    warranting its admission” even “over claims of prejudice.” High,
    
    2012 UT App 180
    , ¶ 27 (quotation simplified); see also Gonzalez,
    
    2015 UT 10
    , ¶¶ 37, 40 (stating that “even where gang-related
    evidence is prejudicial, it is not necessarily unfairly prejudicial
    and therefore should be admitted where it has high probative
    value,” and instructing trial courts that “they may admit [gang-
    related] evidence when it is introduced for a proper purpose and
    under the right circumstances”).
    ¶49 In this case, the probative value of the gang-related
    evidence was high. As the State points out, this evidence
    provided a motive as to why Gallegos and Cellmate would
    change their stories about who owned the shank. Even Gallegos
    acknowledges that the evidence tended to show that the two
    men “owe[d] a duty of loyalty to one another” that included
    sometimes “tak[ing] other charges for their fellow gang
    members,” and that at least some gang evidence was
    “reasonably necessary for the State to try to refute Gallegos’s
    defense that the shank belonged to Cellmate.” But Gallegos
    claims the court admitted too much gang evidence, specifically
    taking issue with the admission of photographs of Gallegos’s
    and Cellmate’s tattoos, asserting that “they were highly
    prejudicial and not necessary to establish gang affiliation.”
    20190029-CA                     26               
    2020 UT App 162
    State v. Gallegos
    ¶50 We take Gallegos’s point that, after the jury had already
    learned that the two men were in affiliated gangs that impressed
    duties of loyalty upon their members, the additional admission
    of photographs of their tattoos had relatively little (and
    cumulative) marginal probative value. But it is also true that the
    admission of the tattoo evidence added relatively little
    additional risk of unfair prejudice. Gallegos asserts that showing
    the jury photographs of the tattoos suggested to the jury that it
    should “reach a decision on an improper basis—that Gallegos
    was ‘inked up’ and had a criminal disposition.” But the jury
    already knew that the two men had a criminal history—at the
    time the shank was discovered, they were sharing a cell in the
    maximum-security section of the Utah State Prison. Where a
    piece of evidence has relatively low probative value, but also
    presents a relatively low risk of unfair prejudice, a trial court
    does not abuse its discretion by concluding that the risk of unfair
    prejudice from admitting the evidence does not “substantially
    outweigh” its probative value. See Utah R. Evid. 403; see also, e.g.,
    State v. Bowden, 
    2019 UT App 167
    , ¶ 22, 
    452 P.3d 503
    .
    ¶51 Accordingly, in this case the trial court did not abuse its
    discretion in admitting any of the gang evidence proffered by
    the State, including the photographs of Gallegos’s and
    Cellmate’s tattoos.
    III
    ¶52 Next, Gallegos challenges the introduction of evidence
    related to his and Cellmate’s custody and sentencing. In
    evaluating Gallegos’s argument, it is important to distinguish
    between the two different types of evidence to which this
    argument refers. First, Gallegos is concerned about evidence
    regarding the respective sentences Gallegos and Cellmate were
    serving in prison as of the date the shank was discovered.
    Second, Gallegos is also referring to evidence regarding the
    potential sentence Gallegos might receive if convicted of the
    20190029-CA                     27               
    2020 UT App 162
    State v. Gallegos
    charged crime at issue during the trial. During oral argument,
    Gallegos clarified that his challenge implicates both types of
    sentencing evidence.
    ¶53 By pretrial motion, the State sought leave to admit the
    first type of evidence: information about the length of sentence
    both men were serving at the time the shank was discovered, as
    well as their potential eligibility for parole. The State asserted
    that this evidence went a long way toward explaining why
    Cellmate—who was in prison serving a sentence of LWOP—
    might attempt to take the criminal charge for possessing the
    shank, and why Gallegos—who was eligible for parole and had
    a hearing coming up—would not want to. The trial court
    granted the State’s motion, and allowed the State to tell the jury
    about the sentences that Gallegos and Cellmate had been serving
    at the time the shank was discovered, as well as their parole
    statuses. During trial, the State presented that evidence through
    one of the prison investigators, who testified that Cellmate was
    serving a sentence of LWOP and was therefore not eligible for
    parole, but that Gallegos was serving a sentence that made him
    eligible for parole and that, at the time the shank was
    discovered, he had a parole hearing coming up in ten months.
    ¶54 The State’s pretrial motion contained no request for
    permission to inform the jury about the potential sentence that
    Gallegos could serve if convicted of possession of a dangerous
    weapon by a restricted person—the crime that was the subject of
    the trial. And the State may not have had any specific intention
    to present any such evidence. However, as noted, the State did
    play for the jury audio recordings of phone calls Gallegos made
    from the prison; it introduced this evidence largely because,
    during the conversations, Gallegos can be heard explaining the
    issues with his prison “books,” and why he agreed to take
    responsibility for the shank during the prison disciplinary
    proceedings. But during two of those phone calls, Gallegos
    20190029-CA                    28              
    2020 UT App 162
    State v. Gallegos
    happens to mention that he has been charged with a first-degree
    felony that carries a potential sentence of “five-to-life.”
    ¶55 Following the introduction of the audio recordings, the
    State made no further reference to the “five-to-life” statements,
    either in questioning witnesses or in making argument. Gallegos,
    however, mentioned the statements several times. Shortly after
    the recordings were played for the jury, defense counsel asked
    the prison investigator to explain what “five-to-life” meant.
    After the witness explained that it meant that Gallegos “was
    facing from five years in prison to life” if convicted, counsel
    asked: “So for this offense, [Gallegos] could serve life in prison?”
    Then during her closing argument, defense counsel again raised
    the issue, noting that Gallegos faced “five-to-life” and told the
    jurors to ask themselves, “Is this justice?,” and then offered her
    view that it was not.
    A
    ¶56 We have no trouble concluding that, in this case, the first
    type of evidence—information about the sentences Gallegos and
    Cellmate were serving at the time the shank was discovered, and
    their parole statuses—was properly admitted. The probative
    value of that evidence was high: it helped explain why Gallegos
    and Cellmate might change their stories, once criminal charges
    were filed against Gallegos, and indicate that the shank
    belonged to Cellmate. Because Cellmate was serving a sentence
    of LWOP and was not going to be eligible for parole no matter
    what, adding another term of years onto his sentence would
    make no practical difference to him. But because Gallegos had a
    parole hearing coming up, being convicted of another crime
    could potentially affect his parole eligibility. And the evidence
    did not come with much risk of unfair prejudice. Ordinarily,
    informing a jury of a defendant’s or a witness’s criminal history
    might pose a risk of unfair prejudice. See, e.g., Robinson v. Taylor,
    
    2015 UT 69
    , ¶ 40, 
    356 P.3d 1230
     (holding that admission of a
    20190029-CA                     29               
    2020 UT App 162
    State v. Gallegos
    defendant’s otherwise irrelevant criminal history unfairly
    prejudiced the defendant). But here, the jury already knew, due
    to the nature of the case, that these men were in a maximum-
    security prison; telling the jury the nature of the sentences they
    were serving did not add much appreciable risk of unfair
    prejudice. Accordingly, the court did not abuse its discretion
    when it granted the State’s motion and allowed it to introduce
    evidence of Gallegos’s and Cellmate’s sentences and parole
    statuses, relative to the sentences they were already serving.
    B
    ¶57 We reach a different conclusion, however, with regard to
    whether the second type of evidence should have been
    admitted. 5 Ordinarily, a jury considering a defendant’s guilt is
    5. After reviewing the record, we are not at all convinced that
    Gallegos adequately preserved for our review the specific
    question of whether the “five-to-life” statements should have
    been admitted into evidence. Gallegos did not make a specific
    request that this evidence be excluded; he certainly made no
    request that the “five-to-life” references be redacted from the
    audio recordings. Indeed, the State’s motion only concerned
    itself with the first type of sentence/parole status evidence,
    relating to the sentences Gallegos and Cellmate were already
    serving, and the court’s ruling allowing admission went only to
    that request. We are therefore not persuaded by Gallegos’s
    contention that his opposition to the State’s motion preserved his
    objection to the “five-to-life” evidence that came in later. But the
    State does not argue that any part of Gallegos’s objection is
    unpreserved, and has therefore waived the preservation issue.
    See State v. Johnson, 
    2017 UT 76
    , ¶ 16, 
    416 P.3d 443
     (“When a
    party fails to raise and argue an issue on appeal, . . . that issue is
    waived and will typically not be addressed by the appellate

    895 F.2d 1198
    ,

    Id.
     ¶ 17 n.5. More recently,
    however, our supreme court has indicated that appellate courts
    have “discretion” in this situation to either “raise a preservation
    issue on our own initiative when it provides an alternative basis
    for affirmance,” or to “decide to address the matter on appeal
    despite the lack of preservation.” See State v. Malo,

    ,
    ¶ 20 n.7, 
    469 P.3d 982
    . In this situation, we elect to address the
    matter despite the apparent lack of preservation; we do so not
    only because the parties have fully briefed the issue and
    presented it for our review, but also because we are reversing on
    the issue of the improperly-admitted shank evidence, and we
    therefore make an effort to give the parties guidance regarding
    the sentencing evidence that might be useful on remand. Were
    we not already reversing for other reasons, we would likely have
    exercised our discretion differently, for the reasons ably
    described in the dissent. See infra ¶¶ 76–78.
    20190029-CA                    31               
    2020 UT App 162
    State v. Gallegos
    “swayed by [its] sympathetic or antipathetic feelings toward a
    defendant because of an anticipated sentence.” See Cude, 784
    P.2d at 1203.
    ¶58 The audio recordings in which the “five-to-life” references
    were embedded were properly admitted for other purposes, and
    Gallegos does not argue to the contrary. But those recordings
    could have served their intended purpose—to show that
    Gallegos had useless “books” and was using Cellmate’s account
    for purchases, and therefore had incentive to take upon himself
    all administrative blame for the shank—without the largely
    extraneous “five-to-life” references. Indeed, those specific
    portions of the audio recordings could have been redacted
    without unduly impacting the recordings’ evidentiary value.
    The “five-to-life” references therefore had very low probative
    value, yet came with significant potential for unfair prejudice.
    ¶59 The State asserts that the information about the potential
    “five-to-life” sentence came into evidence more or less
    inadvertently. In its written motion, the State had not specifically
    sought to introduce any evidence about the potential sentence
    facing Gallegos, and the State did not make any further reference
    to that evidence in support of its case. As the State correctly
    points out in its brief, “the State’s focus in questioning and
    argument was not on what Gallegos’s potential sentence would
    be, only that it could (or not) delay his [parole] release date.” The
    State also notes that it was Gallegos—and not the State—who
    later attempted to use the five-to-life information to his
    advantage, explicitly arguing during closing that the jury should
    acquit because, among other things, imposing a sentence of five-
    years-to-life under these circumstances would be unjust.
    ¶60 But the fact that the State may not have had a specific
    intent to introduce that evidence does not alter the fact that it
    should not have been admitted. And we credit Gallegos’s
    argument that, after the “five-to-life” references came in, his
    20190029-CA                     32               
    2020 UT App 162
    State v. Gallegos
    attorney had to make the best of that evidence, cf. State v. Cruz,
    
    2016 UT App 234
    , ¶ 44, 
    387 P.3d 618
     (stating that “once a court
    has ruled counsel must make the best of the situation”), and
    therefore attempted to make the best argument about the “five-
    to-life” references that she could.
    ¶61 Accordingly, while the first type of sentencing evidence—
    regarding the sentences Gallegos and Cellmate were already
    serving—was properly admitted, the second type of sentencing
    evidence—that Gallegos faced a five-years-to-life sentence for
    the charged crime—was not. 6 That evidence had little probative
    value, yet carried with it significant potential for unfair
    prejudice, and thus was subject to exclusion under rule 403.
    IV
    ¶62 Finally, we must analyze the prejudicial effect of the
    errors we have identified. “Not every trial error requires
    reversal.” State v. Klenz, 
    2018 UT App 201
    , ¶ 64, 
    437 P.3d 504
    (quotation simplified). In particular, “[a]ny error, defect,
    irregularity or variance which does not affect the substantial
    rights of a party shall be disregarded.” Utah R. Crim. P. 30(a); see
    also State v. S.H., 
    2002 UT 118
    , ¶ 26, 
    62 P.3d 444
     (stating that “an
    appellate court will not overturn a jury verdict for the admission
    of improper evidence if the admission of the evidence did not
    reasonably [a]ffect the likelihood of a different verdict”). Such
    errors are not reversible unless there is a “reasonable likelihood
    that the error[s] affected the outcome of the proceedings.” Klenz,
    
    2018 UT App 201
    , ¶ 64 (quotation simplified). “A reasonable

    admitted, we take pains to point out that we do not necessarily
    fault the trial court, which was never specifically asked to
    exclude the evidence. As noted above, supra note 5, this issue
    may well have been unpreserved.

    State v. Gallegos
    likelihood requires a probability sufficient to undermine
    confidence in the outcome.” 
    Id.
     (quotation simplified).
    ¶63 In analyzing the prejudicial effects of improperly
    admitted evidence, it is often useful to assess the strength of the
    State’s case, both with and without the evidence. See Cruz, 
    2016 UT App 234
    , ¶ 48 (stating that “when assessing an error’s
    harmfulness, we look, in part, to the overall strength of the
    State’s case” (quotation simplified)). In this case, the State’s best
    evidence was Gallegos’s and Cellmate’s previous admissions,
    both the day the shank was discovered as well as during later
    follow-up interviews and prison disciplinary proceedings, that
    the shank belonged to Gallegos. At trial, however, Gallegos
    offered a strong rebuttal to those previous admissions,
    presenting evidence explaining why his original account was not
    accurate, including Cellmate’s live testimony wherein Cellmate
    not only testified that both the shank and the shoe in which it
    was found were solely his, but described in some detail how he
    had fashioned it from the bed frame. The ultimate question in
    the case was whether the jury would believe the initial
    admissions that the shank was Gallegos’s, or the later evidence
    that the shank was Cellmate’s.
    ¶64 In an effort to bolster their respective sides of that
    question, both the State and Gallegos pointed to evidence
    tending to corroborate their version of events. Gallegos pointed
    out that he had good reason to want to falsely accept
    responsibility for the shank when the only consequence at issue
    was internal prison discipline, such as fines or different cell
    assignments, because his “books” were full and both he and
    Cellmate wanted to keep Cellmate’s books clean, and because he
    was trying to protect Cellmate’s ability to be moved out of
    maximum security and into the general prison population. The
    State, in contrast, pointed out that Cellmate had every reason to
    falsely accept responsibility for the shank during the criminal
    proceedings, because he was serving a sentence of LWOP while

    2020 UT App 162
    State v. Gallegos
    Gallegos was still eligible for parole, and another conviction
    could hurt his chances of getting paroled.
    ¶65 In this context, introduction of evidence that Gallegos had
    previously possessed a similar shank was powerful evidence
    that may very well have made a difference to the jury’s
    evaluation of which version of events to believe. One indication
    that this evidence was important was the State’s emphasis of it
    during closing argument, including particular emphasis that the
    previous shank was very similar to the present shank. See State v.
    Ellis, 
    2018 UT 2
    , ¶ 43, 
    417 P.3d 86
     (stating that one factor leading
    to the conclusion that the admission of the evidence was not
    harmless was that “[t]he prosecution emphasized this testimony
    during closing argument”). And during the jury instruction
    conference, outside the presence of the jury, the State specifically
    requested that the instructions regarding constructive possession
    include reference to previous possession, asserting that previous
    possession was “pretty important” and was “a pretty pertinent
    element” in this case. Under the circumstances, we agree that the
    prior shank possession evidence was important, and conclude
    that there was a reasonable likelihood of a different outcome had
    that evidence been withheld from the jury’s consideration.
    ¶66 The other piece of improperly admitted evidence—the
    apparently inadvertent references to “five-to-life”—is less of a
    concern, and would not have warranted reversal on its own. As
    noted above, a jury determining whether a defendant is guilty
    should not consider what punishment might result from a guilty
    verdict. But in this case, Gallegos’s attorney appeared to
    consider this evidence somewhat helpful, at least in a way, to her
    client’s cause: on several occasions she reminded the jury that
    the potential sentence was five-years-to-life and expressed her
    view that such a punishment was out of proportion to the
    severity of the charged crime. On balance, the amount of
    prejudice visited upon Gallegos from the improper admission of
    this piece of evidence was likely slight.

    2020 UT App 162
    State v. Gallegos
    ¶67 In the end, we conclude that there is a reasonable
    likelihood that the outcome of the trial would have been
    different had the evidence of Gallegos’s prior shank possession
    been excluded. Because our confidence in the outcome of the
    trial is sufficiently undermined, we must reverse.
    CONCLUSION
    ¶68 The trial court did not abuse its discretion by admitting
    evidence that Gallegos and Cellmate were in affiliated gangs,
    including evidence that each of them had adorned their bodies
    with gang-related tattoos. The court likewise did not abuse its
    discretion in admitting evidence regarding the sentences that
    Gallegos and Cellmate were serving at the time the shank was
    discovered in their shared cell, or their then-current parole
    statuses. But evidence that Gallegos previously possessed a
    similar shank should not have been admitted, nor should
    evidence that the potential sentence upon a guilty verdict in this
    case was to be “five-to-life.” And admission of the previous-
    shank evidence was not harmless, because there is a reasonable
    likelihood that, without it, the outcome of the trial would have
    been different.
    ¶69 Accordingly, we reverse Gallegos’s conviction and
    remand this case for a new trial.
    POHLMAN, Judge (concurring and dissenting):
    ¶70   I respectfully concur in part and dissent in part.
    ¶71 I agree with the majority’s analysis in Part II concluding
    that the trial court did not abuse its discretion in admitting gang
    evidence, including the photographs of Gallegos’s and
    Cellmate’s tattoos. I also agree with the majority’s analysis in
    20190029-CA                    36               
    2020 UT App 162
    State v. Gallegos
    Part III.A rejecting Gallegos’s challenge to the admission of
    evidence about the respective prison sentences he and Cellmate
    were serving when the shank was discovered.
    ¶72 I part ways with my colleagues in their conclusion in Part
    III.B that evidence of Gallegos’s potential sentence was admitted
    in error. Where Gallegos did not object to the admission of this
    evidence, I believe we have no grounds on which to reverse.
    ¶73 I also disagree with the majority’s conclusion in Parts I
    and IV that Gallegos’s conviction should be reversed on the basis
    that the trial court erred in admitting evidence of his prior shank
    possession. I view questions of admissibility under rule 404(b) as
    among the most difficult to analyze, and the combination of our
    precedent and the deferential standard of review leaves me less
    convinced than my colleagues that the prior shank evidence
    should have been excluded. But even if I were to agree with the
    majority’s analysis on this issue, I would still affirm Gallegos’s
    conviction. Unlike my colleagues, I do not consider it reasonably
    likely that the jury would have returned a different verdict had
    the prior shank evidence not been admitted. And on that basis, I
    would affirm.
    I. Potential Sentence Evidence
    ¶74 Gallegos argues that the trial court abused its discretion in
    allowing for the admission of his statements (on recorded phone
    calls) that he was facing a “five-to-life” sentence if convicted in
    this case. The majority begins its analysis on this point by
    observing that Gallegos did not preserve an objection to the
    admission of this evidence. See supra note 5. I agree with that
    observation.
    ¶75 As part of the State’s pretrial motion, the State provided
    Gallegos with a transcript of the excerpts of the audio recordings
    it intended to introduce at trial so that Gallegos could focus his
    objection. Gallegos then moved to exclude certain portions of the
    20190029-CA                    37               
    2020 UT App 162
    State v. Gallegos
    recordings, but he lodged no objection to the admission of the
    “five-to-life” statements. Similarly, Gallegos did not object at
    trial when the State played the audio recordings of the phone
    calls in which the “five-to-life” statements could be heard. 7
    ¶76 As the majority notes, although the State did not raise the
    issue of preservation, we have the discretion to reject Gallegos’s
    challenge on that basis. See supra note 5 (citing State v. Malo, 
    2020 UT 42
    , ¶ 20 n.7, 
    469 P.3d 982
    ). I would exercise that discretion
    here.
    ¶77 It is well-settled that “[o]ur adversary system . . . relies
    generally on objections from parties to police the admissibility of
    evidence,” and “[w]e do not require or even expect our trial
    judges to exercise their own independent judgment on the
    question of admissibility.” State v. Hummel, 
    2017 UT 19
    , ¶ 109,
    
    393 P.3d 314
    . And that, I believe, is why our supreme court has
    stated that there is “no room for reversal of a trial judge under
    an abuse of discretion standard on a ground that was not
    specifically presented to the district court.” State v. Thornton, 2017
    7. This appears to have been intentional. The State drew no
    attention to the “five-to-life” statements, but, as the majority
    notes, defense counsel drew specific attention to them in cross-
    examination of the prison investigator and suggested to the jury
    that justice would not be served if a conviction for being caught
    with a shank were to lead to such a lengthy sentence. See supra
    ¶¶ 8, 55. The majority suggests that counsel was just making the
    best of the situation once the evidence came in. 
    Supra ¶ 60
    . But I
    view it differently. This was not a situation where counsel was
    surprised by a statement from a live witness or where the court
    had ruled the evidence admissible over the objection of counsel.
    If counsel had not wanted the jury to hear the “five-to-life”
    statements, counsel had every opportunity to seek their
    exclusion.

    ; see also State v. King, 
    2006 UT 3
    , ¶¶ 23–
    24, 
    131 P.3d 202
     (finding no abuse of discretion when the trial
    court did not consider an issue sua sponte).
    ¶78 Here, the question of the admissibility of the evidence of
    Gallegos’s potential sentence is one we review for abuse of
    discretion. See supra ¶ 11. Because Gallegos did not object to the
    admission of this evidence, I find no room to conclude that the
    trial court abused its discretion in not sua sponte excluding this
    evidence.
    II. Prior Shank Possession Evidence
    ¶79 As the majority explains, “not every trial error requires
    reversal.” Supra ¶ 62 (quotation simplified); State v. Klenz, 
    2018 UT App 201
    , ¶ 64, 
    437 P.3d 504
    . An error in this case would
    require reversal only if it is reasonably likely that the decision to
    admit evidence of Gallegos’s previous shank possession altered
    the jury’s verdict. See State v. Kohl, 
    2000 UT 35
    , ¶ 17, 
    999 P.2d 7
    (“We will reverse an erroneous evidentiary ruling only if, absent
    the error, there is a reasonable likelihood that there would have
    been a more favorable result for the defendant.” (quotation
    simplified)). I do not think that it did.
    ¶80 To prove possession in this case, the State advanced the
    theory that Gallegos constructively possessed the shank. See
    generally State v. Workman, 
    2005 UT 66
    , ¶¶ 31–33, 
    122 P.3d 639
    (describing how to prove possession on a constructive
    possession theory). The State’s theory required it to prove that
    there was “a sufficient nexus” between Gallegos and the shank
    to permit an inference that he “had both the power and the
    intent to exercise dominion and control” over the weapon. See
    State v. Clark, 
    2015 UT App 289
    , ¶ 14, 
    363 P.3d 544
     (quotation
    simplified). In meeting its burden, the State did not have to
    prove that Gallegos possessed the shank to the exclusion of
    Cellmate. In fact, the State’s theory at trial was that “these two
    men jointly possessed this weapon.”
    20190029-CA                     39               
    2020 UT App 162
    State v. Gallegos
    ¶81 I believe that even without the prior shank evidence, the
    State would have easily convicted Gallegos for constructive
    possession because its case against him was unusually strong.
    ¶82 To begin with, Gallegos admitted ownership of the shank
    not once, not twice, but three different times. He claimed
    ownership on the day it was found in his prison cell; he claimed
    ownership a few weeks later as part of a prison administrative
    hearing; and, he again claimed ownership during a subsequent
    interview with a prison investigator, even identifying where the
    shank was found. And when asked by the investigator why he
    had the shank, Gallegos responded, “Uh, we’re in prison,” and
    commented, “It’s hit or miss, sometimes you guys get me,
    sometimes you don’t.” The jury also heard that the shank
    appeared to have been carved out of the top bunk where
    Gallegos slept.
    ¶83 But that’s not all. The jury heard testimony that shanks
    are “pretty common” in the prison and that Gallegos and
    Cellmate, as members of affiliated gangs, are “supposed to have
    some sort of weapon with them at all times.” A gang expert
    testified that it is “very common” for gang members to share
    shanks, explaining that they may have to share “between each
    other, between cell mates.” And consistent with the expert’s
    testimony, Cellmate confirmed for the jury that he and Gallegos
    would “share stuff.”
    ¶84 The jury also listened to recordings of Gallegos’s phone
    calls in which he discussed the charges against him. Rather than
    disavowing knowledge of the shank, he explained that he was
    hopeful the shank possession case against him would “get
    dismissed,” saying, “I already got . . . my little strategy . . .
    figured out ’cause things played out a certain way.” He said, “I
    got . . . somebody that’s taken the . . . puttin’ their hand out for it
    . . . that it was theirs.”
    20190029-CA                      40                
    2020 UT App 162
    State v. Gallegos
    ¶85 All this evidence points heavily to Gallegos’s guilt. And
    even though Cellmate testified at trial that he made the shank
    and hid it in his shoe, 8 he also told the jury that he and Gallegos
    “shared things,” and he never claimed that Gallegos was
    unaware of the shank. That is significant. The State did not need
    to prove that the shank belonged exclusively to Gallegos. It had
    to prove only that Gallegos had the power and intent to exercise
    dominion and control over it. And given Gallegos’s multiple
    admissions, combined with the evidence that Gallegos and
    Cellmate were prone to share things, including weapons, I have
    no trouble concluding that the jury would have convicted
    Gallegos even without the prior possession evidence.
    ¶86 The majority acknowledges much of this evidence but
    believes it is reasonably likely that it was the evidence of
    Gallegos’s prior shank possession that swayed the jury toward a
    conviction. I disagree for several reasons.
    ¶87 First, while rule 404(b) evidence has the potential to be
    damaging, evidence of Gallegos’s prior shank possession was
    not particularly revelatory. After all, the jury heard evidence that
    Gallegos claimed ownership of the shank in this case—three
    different times, on different days, to different people. Thus,
    8. When asked why he claimed ownership of the shank at trial,
    after having previously disavowed such ownership, Cellmate
    responded, “Because it was mine, and I don’t feel it’s right to
    have somebody else take the fall for it.” As noted above, the jury
    could have still convicted Gallegos of constructive possession
    even if it was inclined to believe Cellmate’s belated confession.
    But the jury also had plenty of reason to distrust Cellmate. His
    claims of concern likely fell on deaf ears after the jury learned
    that he was in prison for killing three people (and trying to kill a
    fourth) and had previous convictions for theft by deception and
    forgery.
    20190029-CA                     41               
    2020 UT App 162
    State v. Gallegos
    hearing evidence that he claimed ownership of a different shank
    several years earlier was unlikely to carry significant weight.
    ¶88 Second, in addition to admitting that he possessed the
    shank found in this case, Gallegos suggested to the prison
    investigator that he has possessed shanks at other times when he
    said, “It’s hit or miss, sometimes you guys get me, sometimes
    you don’t.” This evidence, along with evidence from the gang
    expert that it was common for gang members to carry and share
    homemade weapons, blunted the admission of his earlier shank
    possession.
    ¶89 Third, the majority says that the State emphasized the
    prior possession evidence in closing. See supra ¶ 65. I read the
    record differently. It is true that the prosecutor mentioned the
    prior shank possession in his closing statement. But the State
    placed no greater emphasis on it than the other evidence
    pointing to Gallegos’s guilt. The State did not treat the prior
    possession as the centerpiece of its story. Rather, it treated it as
    just one piece of evidence in a particularly incriminating puzzle.
    ¶90 Fourth, the trial court gave a limiting instruction on the
    previous shank possession evidence, advising the jury to
    consider the evidence for “the limited purpose” of considering
    whether “there was a sufficient nexus” between the shank and
    Gallegos and instructing the jury not to convict in this case on
    the basis that Gallegos may have committed another act at some
    other time. See supra ¶ 6. This instruction further tempered any
    remaining effect the admission of the prior possession evidence
    may have had. See State v. Calvert, 
    2017 UT App 212
    , ¶ 45, 
    407 P.3d 1098
    .
    ¶91 In sum, I would affirm Gallegos’s conviction. I see no
    grounds to conclude that the trial court abused its discretion in
    not sua sponte excluding the evidence of Gallegos’s potential
    sentence where Gallegos did not object to its admission. And
    even assuming error in the admission of evidence of the
    20190029-CA                     42               
    2020 UT App 162
    State v. Gallegos
    previous shank possession, I am confident that given the unique
    evidence in this case, the jury would still have convicted
    Gallegos without it.
