    STATE v. ROMERO
    Opinion of the Court
    OPINION
    Presiding Judge Miller authored the opinion of the Court, in which
    Judge Espinosa concurred and Chief Judge Eckerstrom specially
    concurred.
    M I L L E R, Presiding Judge:
    ¶1           Joseph Romero was convicted after a jury trial of
    second-degree murder and sentenced to a presumptive term of
    sixteen years. Romero argues the trial court erred when it denied
    his motion to dismiss the indictment due to pre-indictment delay,
    denied his motion to preclude testimony from the state’s firearms
    expert, and granted the state’s motion to preclude testimony from
    his proffered expert on firearms examination methodology. Romero
    also argues the trial court erred by entering a criminal restitution
    order at sentencing. For the reasons that follow, we vacate the
    criminal restitution order but otherwise affirm Romero’s convictions
    and sentences.
    Factual and Procedural Background
    ¶2            We view the facts in the light most favorable to
    sustaining the jury’s verdict and resolve all reasonable inferences
    against Romero. State v. Haight-Gyuro, 
    218 Ariz. 356
    , ¶ 2, 
    186 P.3d 33
    , 34 (App. 2008). In June 2000, S.M. was killed by two gunshot
    wounds to his face and back. Among other items, a cellular
    telephone and six .40-caliber shell casings were discovered near
    S.M.’s body. Nearly one month later, when Romero was stopped by
    police officers in an unrelated matter, he possessed a .40-caliber
    Glock magazine. Officers also found a .40-caliber Glock handgun
    without its magazine along the path Romero had travelled just prior
    to his encounter with the police. This firearm later would be linked
    to the shell casings discovered near S.M.
    ¶3         Seven years after the homicide, a “cold case” unit
    examined information from the cell phone found next to S.M.’s
    body, which led investigators to Romero. Based on this connection,
    2
    STATE v. ROMERO
    Opinion of the Court
    a firearms expert was asked to conduct a ballistics test of Romero’s
    Glock handgun. The expert fired the handgun and concluded that
    the indentations it made on the back of each expelled shell casing
    matched those on the shell casings found near S.M.’s body.
    ¶4          Romero was charged by indictment with first-degree
    murder. After a jury trial, he was found guilty of the lesser-included
    offense of second-degree murder and sentenced to sixteen years’
    imprisonment.1 This timely appeal followed.
    Pre-indictment Delay
    ¶5           Romero argues the trial court erred by denying his
    motion to dismiss the charge due to pre-indictment delay based on
    the seven years that had elapsed between the date of S.M.’s death
    and when the state began investigating the case again. We review a
    court’s ruling on a motion to dismiss for an abuse of discretion.
    State v. Medina, 
    190 Ariz. 418
    , 420, 
    949 P.2d 507
    , 509 (App. 1997).
    ¶6           “To establish that pre-indictment delay has denied a
    defendant due process, there must be a showing that the prosecution
    intentionally delayed proceedings to gain a tactical advantage over
    the defendant or to harass him, and that the defendant has actually
    been prejudiced by the delay.” State v. Broughton, 
    156 Ariz. 394
    , 397,
    
    752 P.2d 483
    , 486 (1988). Romero does not allege and the record
    contains no evidence that the state intentionally delayed indicting
    him to obtain a tactical advantage. Rather, Romero contends the
    state was negligent in waiting until 2007 to investigate the cellular
    telephone found next to S.M.’s body. But even assuming the state
    had been negligent in this regard, it does not demonstrate the delay
    had been intentional and designed to “gain a tactical advantage”
    over Romero or “to harass him.” 
    Id. Because Romero
    has not
    established this required element, he is not entitled to relief for pre-
    indictment delay under the test set forth in Broughton. See 
    id. ¶7 Romero
    argues, however, that he is not required to
    demonstrate the state intentionally delayed the prosecution to gain a
    tactical advantage. He contends this requirement is the result of our
    1The   jury in Romero’s first trial could not reach a verdict.
    3
    STATE v. ROMERO
    Opinion of the Court
    supreme court’s misinterpretation of United States v. Marion, 
    404 U.S. 307
    (1971), and United States v. Lovasco, 
    431 U.S. 783
    (1977). Romero
    appears to ask that we instead apply a balancing test similar to that
    adopted by some federal circuit courts. See, e.g., Howell v. Barker, 
    904 F.2d 889
    , 894-95 (4th Cir. 1990); United States v. Moran, 
    759 F.2d 777
    ,
    782 (9th Cir. 1985). But we are “bound by decisions of the Arizona
    Supreme Court and ha[ve] no authority to overturn or refuse to
    follow its decisions.” State v. Long, 
    207 Ariz. 140
    , ¶ 23, 
    83 P.3d 618
    ,
    623 (App. 2004).       Accordingly, any changes to the test for
    determining whether a defendant is entitled to dismissal of charges
    because of pre-indictment delay “would be in the exclusive purview
    of [the supreme court].” State v. McPherson, 
    228 Ariz. 557
    , ¶ 16, 
    269 P.3d 1181
    , 1187 (App. 2012).
    ¶8           Moreover, under either test Romero was required to
    demonstrate that he actually was prejudiced by the delay, which he
    has failed to do. See 
    Howell, 904 F.2d at 895
    ; 
    Moran, 759 F.2d at 782
    .
    “To make a showing of actual and substantial prejudice, ‘it is not
    enough to show the mere passage of time nor to offer some
    suggestion of speculative harm; rather the defendant must present
    concrete evidence showing material harm.’” State v. Dunlap, 
    187 Ariz. 441
    , 450, 
    930 P.2d 518
    , 527 (App. 1996), quoting United States v.
    Anagnostou, 
    974 F.2d 939
    , 942 (7th Cir. 1992).
    ¶9           Romero argues his ability to mount a defense was
    prejudiced by the passage of time because potential witnesses had
    died, witnesses’ memories had faded, and he was not on notice to
    preserve evidence showing his whereabouts at the time of the
    murder. Romero did not identify unavailable witnesses or possible
    testimony. Similarly, he has not specified what evidence he could
    have gathered with respect to ownership of the handgun attributed
    to him that was not already in the law enforcement record. Thus,
    Romero has not presented concrete evidence that he was actually
    and substantially prejudiced by the delay. See 
    Broughton, 156 Ariz. at 397
    , 752 P.2d at 486. Based on the record before us, the trial court
    did not err by refusing Romero’s request to dismiss the charge.
    4
    STATE v. ROMERO
    Opinion of the Court
    Rule 702
    ¶10          Romero next raises two arguments related to the
    admissibility of expert testimony under Rule 702, Ariz. R. Evid.
    First, he contends the trial court erred by denying his motion to
    preclude the testimony of the state’s firearms examiner, Frank
    Powell, on the ground the examination was not the product of
    reliable principles and methods. Romero also asserts the court erred
    in precluding his experimental psychologist expert, Ralph Haber,
    from testifying at trial about scientific criticisms of all firearm
    identifications.    We review a trial court’s decisions on the
    admissibility of expert testimony for an abuse of discretion. State v.
    Davolt, 
    207 Ariz. 191
    , ¶ 69, 
    84 P.3d 456
    , 475 (2004).
    ¶11           Effective January 1, 2012, Arizona adopted the language
    of Rule 702, Fed. R. Evid., which reflects the principles set forth in
    Daubert v. Merrell Dow Pharmaceuticals, Inc., 
    509 U.S. 579
    (1993). See
    Ariz. R. Evid. 702 cmt. to 2012 amend.; State v. Perez, 
    233 Ariz. 38
    ,
    ¶ 16, 
    308 P.3d 1189
    , 1193 (App. 2013). Under Rule 702, the trial court
    is to serve as a “gatekeeper[]” that admits testimony it initially finds
    reliable, permitting the jury to weigh what the court has already
    determined to be “reliable, expert testimony.” Ariz. R. Evid. 702 cmt
    to 2012 amend.; see also Perez, 
    233 Ariz. 38
    , ¶ 
    16, 308 P.3d at 1193
    .
    This “gatekeeper” function applies not only to scientific evidence,
    but “also to testimony based on ‘technical’ and ‘other specialized’
    knowledge.” Kumho Tire Co. v. Carmichael, 
    526 U.S. 137
    , 141 (1999).
    Specifically, Rule 702, Ariz. R. Evid., provides:
    A witness who is qualified as an expert by
    knowledge, skill, experience, training, or
    education may testify in the form of an
    opinion or otherwise if:
    (a) the expert’s scientific, technical, or
    other specialized knowledge will
    help the trier of fact to understand
    the evidence or to determine a fact in
    issue;
    5
    STATE v. ROMERO
    Opinion of the Court
    (b) the testimony is        based   on
    sufficient facts or data;
    (c) the testimony is the product of
    reliable principles and methods; and
    (d) the expert has reliably applied the
    principles and methods to the facts of
    the case.
    “Daubert offers additional ‘non-exclusive factors for determining
    whether scientific evidence is admissible,’ including empirical
    testing, peer review, error rate, the existence of standards and
    controls, and the degree to which the theory and technique is
    generally accepted by a relevant scientific community.” Sandretto v.
    Payson Healthcare Mgmt., Inc., 
    234 Ariz. 351
    , ¶ 12, 
    322 P.3d 168
    , 173
    (App. 2014), quoting Ariz. State Hosp./Ariz. Cmty. Protection &
    Treatment Ctr. v. Klein, 
    231 Ariz. 467
    , ¶ 27, 
    296 P.3d 1003
    , 1009 (App.
    2013); see also 
    Daubert, 509 U.S. at 593-94
    .
    Admission of Toolmark Analysis for Firearm Identification
    ¶12          Romero moved to preclude Powell’s testimony,
    asserting the field of firearms identification lacked the reliability
    required by Daubert and Rule 702. Although he did not challenge
    Powell’s expert qualifications, he argued that the field is not a
    science because the theory of unique markings from individual
    firearms cannot be tested under the scientific method. He also
    attacked the field’s subjective methods, the structure and
    functioning of its research literature, and how examiner error rates
    are calculated. Additionally, Romero relied on Dr. Haber to convey
    these general arguments, as well as to expand upon criticisms from
    the National Academy of Science review of forensic sciences in
    6
    STATE v. ROMERO
    Opinion of the Court
    2009.2 The trial court conducted a Rule 702 evidentiary hearing, and
    reviewed Powell’s testimony from the first trial in which he
    described his qualifications as well as the methodology he used to
    match spent casings to a specific firearm. The court found the
    firearms identification evidence “reliable and admissible under
    Arizona’s newly adopted Daubert standard.” On appeal, Romero
    raises the same arguments he did below.
    ¶13          Before Rule 702 changed in 2012, our supreme court
    determined that firearms identification testimony was admissible
    under the previous standard set forth in Frye v. United States, 
    293 F. 1013
    , 1014 (D.C. Cir. 1923). See State v. Miller, 
    234 Ariz. 31
    , ¶¶ 28-31,
    
    316 P.3d 1219
    , 1229 (2013); State v. Macumber, 
    112 Ariz. 569
    , 570-71,
    
    544 P.2d 1084
    , 1085-86 (1976). Although Arizona courts have yet to
    determine whether firearms identification is sufficiently reliable for
    admission under amended Rule 702, we look to federal decisions
    interpreting Federal Rule 702 for guidance. See State v. Green, 
    200 Ariz. 496
    , ¶ 10, 
    29 P.3d 271
    , 273 (2001) (“When interpreting an
    evidentiary rule that predominately echoes its federal counterpart,
    we often look to the latter for guidance.”); Ariz. R. Evid. 702 cmt. to
    2012 amend. (“The 2012 amendment of Rule 702 adopts Federal
    Rule of Evidence 702, as restyled.”).
    ¶14          Several federal district courts have held that firearms
    identification testimony is sufficiently reliable under Daubert and
    Federal Rule 702. See, e.g., United States v. Willock, 
    696 F. Supp. 2d 536
    , 571-72 (D. Md. 2010); United States v. Taylor, 
    663 F. Supp. 2d 2
    Romero    and our specially concurring colleague also cite
    Strengthening Forensic Science in the United States: A Path Forward
    (2009), by the National Research Council of the National Academies
    (hereinafter “NAS Report”), to argue that the principle of unique
    markings on discharged ammunition has not been “scientifically
    demonstrated.” The NAS Report made thirteen recommendations,
    none of which addressed admissibility. 
    Id. at 19-33.
    Instead, the
    report observed that firearms identification is highly dependent on
    skill and training. 
    Id. at 153.
    The NAS Report is not, standing alone,
    dispositive of either the admissibility of firearms identification
    testimony or sufficient to qualify Haber as an expert.
    7
    STATE v. ROMERO
    Opinion of the Court
    1170, 1179-80 (D.N.M. 2009); United States v. Monteiro, 
    407 F. Supp. 2d
    351, 354-55 (D. Mass. 2006). In Monteiro, after a six-day
    evidentiary hearing, the court held that “the underlying scientific
    principle behind firearm identification—that firearms transfer
    unique toolmarks to spent cartridge cases—is valid under Daubert.”
    
    407 F. Supp. 2d
    at 355. Similarly, in Willock, the court determined
    that the standards governing toolmark examination are sufficient to
    permit a qualified expert’s testimony to assist jurors in determining
    whether bullets or cartridges have been fired from a particular
    
    firearm. 696 F. Supp. 2d at 571-72
    .
    ¶15          At the first trial, Powell testified about his background,
    training, and experience in firearms identification. He is a member
    of the Association of Firearm and Toolmark Examiners that
    publishes a quarterly journal. He also testified that he is required to
    complete an annual proficiency exam and that studies indicate an
    error rate around one percent for proficiency tests given to firearms
    examiners. Further, he indicated that the methodology he used to
    analyze the shell casings is accepted by his scientific community as
    valid, and that a second examiner was required to review his work
    and agree with his conclusion before it was reported.
    ¶16           We find the reasoning in Monteiro and Willock
    persuasive and likewise conclude that the methodology governing
    firearms identification is sufficiently reliable, under Daubert and
    Arizona Rule 702, to permit a qualified expert to provide in-court
    technical testimony.3 See 
    Daubert, 509 U.S. at 593-94
    . First, Romero
    failed to develop an argument that changes in firearms identification
    methods call into question Arizona case law admitting such
    testimony under Frye. Nor does he identify a reason Arizona’s
    adoption of the Daubert standard would justify a different result. See
    Miller, 
    234 Ariz. 31
    , ¶¶ 
    28-31, 316 P.3d at 1229
    ; cf. Favela, 
    323 P.3d 716
    , ¶¶ 6, 
    9, 323 P.3d at 718
    , 719. Accordingly, the trial court did not
    3Our   determination is consistent with other Arizona decisions
    in analogous fields of technical expertise. See, e.g., State v. Favela, 
    234 Ariz. 433
    , ¶¶ 6, 9, 
    323 P.3d 716
    , 718, 719 (App. 2014) (expert
    testimony on latent fingerprint and palm print evidence sufficiently
    reliable to satisfy Rule 702 and Daubert).
    8
    STATE v. ROMERO
    Opinion of the Court
    abuse its discretion in denying Romero’s motion to preclude
    Powell’s testimony. See 
    Willock, 696 F. Supp. 2d at 571-72
    ; Monteiro,
    
    407 F. Supp. 2d
    at 354-55; cf. Favela, 
    323 P.3d 716
    , ¶¶ 6, 
    9, 323 P.3d at 718
    , 719.
    ¶17           Romero further argues that even if the trial court
    properly allowed Powell to testify, the court erred by “failing to
    limit his testimony regarding the certainty of his conclusions.” He
    appears to rely on Monteiro in support of this argument. 407 F.
    Supp. 2d at 355. Although the court in Monteiro held that the
    underlying scientific principle behind firearms identification is valid
    under Daubert, it determined that “the subjective nature of the
    matching analysis,” meant “a firearms examiner must be qualified
    through training, experience, and/or proficiency testing to provide
    expert testimony.” 
    Id. The court
    further concluded that a firearms
    expert may give an opinion of a match “to a reasonable degree of
    certainty in the ballistics field,” but may not testify that there is a
    match “to an exact statistical certainty.” 
    Id. ¶18 But
    Monteiro is distinguishable. Here, unlike the
    examiners in Monteiro, who testified essentially that they could be
    100 percent sure of a match, Powell testified that there was a match
    to “a reasonable degree of scientific certainty.” See 
    407 F. Supp. 2d
    at
    372. Moreover, in Ruiz-Troche v. Pepsi-Cola of Puerto Rico Bottling
    Company, upon which the Monteiro court relied in support of its
    holding, the court of appeals approved allowing an accident
    reconstruction expert to testify to a reasonable degree of scientific
    certainty. Ruiz-Troche v. Pepsi-Cola of Puerto Rico Bottling Co., 
    161 F.3d 77
    , 82 (1st Cir. 1998); see also Monteiro, 
    407 F. Supp. 2d
    at 372.
    Accordingly, the trial court did not err by permitting Powell to
    testify to a reasonable degree of scientific certainty.
    Preclusion of Expert Testimony Criticizing Firearms Identification
    ¶19         Romero next argues the trial court erred in precluding
    his psychology expert from testifying at trial about criticisms of
    firearms identification. The court found Haber not qualified to
    challenge or rebut the testimony, foundation, or opinions of Powell.
    The court also found that Romero sought to introduce Haber’s
    testimony to conduct what amounted to a second Daubert hearing
    9
    STATE v. ROMERO
    Opinion of the Court
    before the jury.4 Accordingly, the court granted the state’s motion to
    preclude Haber’s proposed testimony.
    ¶20           Unlike most Rule 702 issues that courts have faced in
    the last two decades, the question of whether an expert is qualified
    to express a particular opinion is largely unaffected by Daubert, its
    progeny, or the changes to Rule 702. Almost a century ago it was
    black letter law that a person offering an expert opinion must have
    the requisite qualifications on the particular matter. 5 1 Wigmore on
    Evidence § 560 (2d ed. 1923); see also Gaston v. Hunter, 
    121 Ariz. 33
    ,
    51, 
    588 P.2d 326
    , 344 (App. 1978), citing Myers v. Cessna Aircraft Corp.,
    
    553 P.2d 355
    , 370 (Or. 1976). It also was recognized that expertise is
    specific, and experience in one area does not confer expertise in a
    related area. 
    Myers, 553 P.2d at 370-71
    . Stated differently: no expert
    is competent to express an opinion on every subject. Wigmore,
    supra, § 555.
    ¶21         As the proponent of expert testimony, Romero had the
    burden of demonstrating Haber’s qualifications on the particular
    issues. Sandretto, 
    234 Ariz. 351
    , ¶ 
    15, 322 P.3d at 174
    . The trial court
    has broad discretion in admitting or excluding expert testimony, and
    we will not reverse its ruling “unless there is a clear abuse of
    4We   do not address this second reason in view of our decision
    affirming the trial court’s finding that Romero did not show Haber
    qualified to testify about firearms identification.
    5To  the extent Romero or our colleague relies on authorities
    discussing the test described in Rule 702(a)—“specialized
    knowledge [that] will help the trier of fact”—to determine whether
    an expert is “qualified,” they confound separate inquiries. While
    such blending might have been more common pre-Daubert, it was a
    mistake even at that time. Compare State v. Seebold, 
    111 Ariz. 423
    ,
    425, 
    531 P.2d 1130
    , 1132 (1975) (gun shop owner and penetration
    specialist were not qualified about ballistics despite detailed
    knowledge of guns and their use), with

    ¶22          Romero’s proof of Haber’s qualifications was limited to
    general background statements in advance of his testimony about
    firearms identification. Romero did not proffer a curriculum vitae,
    bibliography of published articles, or other record of Haber’s
    experiences and training.         Haber’s graduate education and
    professional background are predominantly in the field of
    experimental psychology. His professional experience included
    psychology-related work in academia as well as consulting in the
    area of eyewitness testimony. He eventually branched out to
    fingerprint analysis after he underwent fingerprint examiner
    training. Haber’s firearms identification experience consisted solely
    of his reviewing the relevant literature and writing a “chapter in the
    California Bar Association’s publication on evidence in the criminal
    courts on firearms and handgun identification.” This was the first
    time he had been retained as a proposed expert in firearms
    identification. Haber admitted he had “no idea what an examiner
    does when he carries out an examination.”
    ¶23          Romero challenges the description of Haber as only a
    psychologist. He posits him as an expert in the scientific field of
    experimental design. Haber’s self-description was not so broad. For
    instance, he taught for six years “as an assistant professor in
    psychology and primarily in experimental psychology and statistics
    and experimental design.” At subsequent academic positions as an
    experimental psychologist, he also taught experimental design. He
    explained that he has been a peer and grant reviewer “on a variety
    of experimental topics where I review them, analyze them both in
    terms of the appropriate experimental designs, the way the
    experiment was carried out, the conclusions reached, the
    interpretations and the statistical methods that were used.” One
    such item involved handgun identification, but Haber provided no
    11
    STATE v. ROMERO
    Opinion of the Court
    details about the grant application he reviewed. He also has done
    review work for several national academies and twenty different
    journals, although apparently none involving journals read by
    firearms and toolmark analysts.
    ¶24          Accepting for the purpose of addressing Romero’s
    argument that Haber has expertise in experimental design, we
    address whether that background qualifies him to testify as an
    expert in firearms identification, where he has “studied this
    literature for three or four years,” but has no practical experience.
    First, we note that experimental design is not a separate field of
    study, but generally describes various empirical models to study
    measurable phenomena. It is a critical component of the scientific
    method. Erica Beecher-Monas, The Heuristics of Intellectual Due
    Process: A Primer for Triers of Science, 75 N.Y.U. L. Rev. 1563, 1578
    (2000) (“Science Primer”) (science consists of assumptions about the
    way the world works, coupled with canons of experimental design
    and theoretical exemplars to address problems and explanations).
    Experimental design is employed in virtually any area susceptible to
    statistical analysis, such as the social, biological, and physical
    sciences. See generally, David H. Kaye & David A. Freedman,
    Reference Guide on Statistics, in Reference Manual on Scientific
    Evidence 90-97 (2d ed. 2000). It is not a one-size-fits-all approach.
    The application of experimental design principles “differ[s] widely
    from field to field.” Science Primer, 75 N.Y.U. L. Rev. at 1629. A
    classic text on experimental design cautions that the researcher
    cannot casually transfer design principles across fields. D.R. Cox,
    Planning of Experiments at vi (1958) (“[T]he practical importance of
    different parts of [experimental design] varies greatly between
    different applied fields.”). The issue is whether Haber could apply
    his knowledge of experimental design to firearms identification.
    ¶25          Assuming that Haber described all of his relevant
    experience, training, and knowledge, the omissions in his ability to
    apply theoretical design knowledge to firearms identification are
    numerous. Before this case, Haber never conducted a toolmark
    analysis, never attempted to identify different firearms, and never
    conducted research on firearms identification. He has no experience
    in any physical sciences on which toolmark analysis rests, such as
    12
    STATE v. ROMERO
    Opinion of the Court
    ballistics, metallurgy, or physics. Despite his general study of the
    firearms identification literature, Haber could not describe the
    methods or protocols of a toolmark analyst.              Had Haber
    demonstrated relevant experience or knowledge in one or more of
    these areas, the issue of his qualifications would have been moot or
    at least a much closer question. See, e.g., Kumho Tire 
    Co., 526 U.S. at 153
    (tire expert qualified based on master’s degree in mechanical
    engineering, manufacturing experience, and tire failure analysis);
    Logerquist v. McVey, 
    196 Ariz. 470
    , ¶¶ 15, 32, 
    1 P.3d 113
    , 117, 124
    (2000) (psychiatrist qualified to testify about amnesia for traumatic
    experiences based on education and clinical experience); Lohmeier v.
    Hammer, 
    214 Ariz. 57
    , ¶¶ 3, 29, 
    148 P.3d 101
    , 104, 108-09 (App. 2006)
    (biomechanical engineer qualified to testify about forces involved in
    vehicle collision based on education, industry experience, and
    research).
    ¶26          Romero and our specially concurring colleague draw a
    different conclusion about Haber’s qualifications, principally relying
    on his general experience in a forensic consulting firm and
    experimental background. That consulting is primarily in the area
    of eyewitness identification and fingerprint analysis. The first area
    is not surprising because eyewitness identification experts
    frequently have psychology backgrounds due to the interplay
    between perception and memory. See, e.g., United States v. Moore,
    
    786 F.2d 1308
    , 1312 (5th Cir. 1986) (noting conclusions of
    psychological studies serve to “‘explode common myths about an
    individual’s capacity for perception’”), quoting United States v. Smith,
    
    736 F.2d 1103
    , 1105 (6th Cir. 1984); State v. Chapple, 
    135 Ariz. 281
    , 291,
    
    660 P.2d 1208
    , 1218 (1983) (expert on eyewitness identification a
    professor specializing in area of experimental and clinical
    psychology dealing with perception, memory retention and recall).
    To qualify as a fingerprint expert, Haber undertook professional
    training, which was the “equivalent to what a fingerprint examiner
    would take to be employed in a crime laboratory.” Haber offered no
    such specialized training or experience with firearms identification.
    Equally important, it is not the role of this court to re-weigh the
    evidence proffered to qualify a person as an expert. Cauble v.
    Osselaer, 
    150 Ariz. 256
    , 258, 
    722 P.2d 983
    , 985 (App. 1986) (abuse of
    discretion standard requires appellate court to uphold trial court’s
    13
    STATE v. ROMERO
    Opinion of the Court
    determination unless unsupported by evidence or absolutely
    contrary to uncontradicted and unconflicting evidence).
    ¶27           Romero alternatively offered to limit Haber’s testimony
    to a general critique of the field, specifically avoiding anything
    Powell did. But this position is implicitly grounded on the
    assumption that a person with experimental design knowledge
    applicable to one field can apply the same principles to an entirely
    different field. Science does not support such an assumption and
    neither does the law.
    ¶28          For instance, in 
    Myers, 553 P.2d at 370
    , the expert was
    proffered to opine about the probable cause of an airplane crash
    based on his experience in “technical, engineering aspects of
    accident investigations.” He was a member of the Society of Air
    Safety Investigators and had flown in the Air Force. 
    Id. The trial
    and appellate courts found specific absences more significant than
    his admittedly pertinent experience in limited areas. The expert
    “had no formal training as an accident investigator, had never
    attended a seminar on that subject, was not an aeronautical
    engineer, was not accredited as an instrument flight pilot, did not
    have a current pilot’s license, and had never flown a light aircraft
    similar to the one involved in this crash.” 
    Id. ¶29 Similarly,
    in United States v. Paul, 
    175 F.3d 906
    , 912 (11th
    Cir. 1999), the proponent sought to use an evidence law professor
    who had co-written an article critical of forensic document
    examiners to rebut the opinion of an expert in that field. Despite his
    obvious expertise in evidence and having reviewed the literature
    about document examiners, his lack of knowledge about
    handwriting analysis precluded his opinions about the examination
    conducted or the field itself. 
    Id. at 911-12.
    Simply stated, even a
    person with expertise in one area must demonstrate sufficient
    knowledge or experience in the pertinent area to qualify as an expert
    in the particular case regarding a specific opinion.
    ¶30          Romero indirectly seeks to counter Paul by relying on
    United States v. Velasquez, 
    64 F.3d 844
    , 848 (3d Cir. 1995), in which the
    appellate court concluded the trial court erred in precluding the
    same law professor from criticizing handwriting standards. The
    14
    STATE v. ROMERO
    Opinion of the Court
    appellate court did not explicitly address the professor’s
    qualifications. 
    Id. Instead, it
    “point[ed] to the Professor’s eight
    years of self-directed research on handwriting analysis and his co-
    authorship of a law review article on the subject.” 
    Id. at 851.
    It also
    noted that the government’s expert was aware of the professor’s
    scholarship, the professor’s criticisms were similar to critiques that
    had been subject to peer review, and the professor’s opinions were
    specific to the methods used by the government’s expert. 
    Id. at 851-
    52. Additionally, the professor had read “nearly all of the literature
    on the subject,” and he had been named an American Bar
    Association Fellow for creating a testing mechanism to certify
    handwriting analysts and to validate the accuracy of their
    identifications. 
    Id. at 847
    n.4. On first look, the Eleventh and Third
    circuits appear to be in conflict because they came to contrary
    conclusions regarding the same law professor arguably offered for
    the same purpose. The differences, however, illustrate that the
    proponent in Velasquez made a considerably more detailed record
    concerning the professor’s actual experience and work in
    handwriting analysis. 6 Whether the circuits still would have
    disagreed about the professor’s qualification to testify had the
    proponents made identical proofs of expertise is unknowable, but
    from the perspective of reported qualifications, there is no conflict in
    the decisions.
    ¶31         Romero also relies on State v. Lehr, 
    201 Ariz. 509
    , 
    38 P.3d 1172
    (2002), for intertwined propositions that expert testimony
    generally supporting a defense argument is sufficient under
    Rule 702 and, in any event, preclusion would violate a defendant’s
    6We   note, however, that the trial court in A.V. By Versace, Inc.
    v. Gianni Versace S.p.A., 
    446 F. Supp. 2d 252
    , 268 (S.D.N.Y. 2006)
    precluded the professor’s testimony, which was offered only to
    critique the field of handwriting analysis in general. In rejecting the
    proffer, the court recognized its ability to assess the weight of the
    opponent’s handwriting expert testimony. 
    Id. at 268
    n.15. There
    was no discussion of the professor’s specific qualifications.
    15
    STATE v. ROMERO
    Opinion of the Court
    Sixth Amendment right to present a defense. 7 Similarly, our
    colleague extends the argument with reliance on a more recent
    expert witness case, State v. Salazar-Mercado, 
    234 Ariz. 590
    , 
    325 P.3d 996
    (2014). We discuss them together. First, in both cases the
    Arizona Supreme Court noted that the qualifications of the defense
    experts were not challenged or in doubt. Lehr, 
    201 Ariz. 509
    , 
    n.12, 38 P.3d at 1181
    n.12; Salazar-Mercado, 
    234 Ariz. 590
    , 
    ¶12, 325 P.3d at 999
    .
    Second, while there are few rights “more fundamental than that of
    an accused to present witnesses in his own defense,” the exercise of
    the right must comply with evidence rules designed to ensure
    fairness and reliability. Chambers v. Mississippi, 
    410 U.S. 284
    , 302
    (1973). As the Eleventh Circuit Court of Appeals explained, “a court
    may constitutionally enforce evidentiary rules to limit the evidence
    an accused (or for that matter any party) may present in order to
    ensure that only reliable opinion evidence is admitted at trial.”
    United States v. Frazier, 
    387 F.3d 1244
    , 1272 (11th Cir. 2004) (right to
    put on meaningful defense did not include unfettered, unreviewable
    opportunity to present expert testimony inadmissible under
    Rule 702).
    ¶32           Finally, we observe that Romero was not deprived of
    the right to challenge Powell’s testimony using the same materials
    Haber referenced. There was a spirited cross-examination of Powell
    about the 2009 NAS Report and several studies criticizing particular
    aspects of firearms identification. The jury heard, by quotation and
    paraphrase, the essence of Haber’s criticisms because much of his
    analysis was derived from the NAS Report. We conclude the
    preclusion of Haber’s testimony on the ground he lacked knowledge
    7 Romero    also notes that Lehr cites Velasquez to support his
    reliance on the latter case. Such reference is misplaced because the
    citation in Lehr does not pertain to expert witness qualifications. 
    201 Ariz. 509
    , ¶ 
    27, 38 P.3d at 1180
    . Rather, Lehr relies on Velasquez in
    support of the principle “that judges determine admissibility of
    evidence and juries decide what weight to give it.” 
    Id. ¶ 24;
    see also
    
    Velasquez, 64 F.3d at 848
    (reversing trial court’s preclusion of
    proffered expert testimony concerning handwriting analysis because
    evidence sufficiently reliable under Rule 702).
    16
    STATE v. ROMERO
    Opinion of the Court
    or practical experience in toolmark analysis did not violate Romero’s
    right to present a defense.
    Criminal Restitution Order
    ¶33          Romero lastly argues, and the state concedes, that the
    trial court erred in entering a criminal restitution order (CRO) at
    sentencing. We agree and find fundamental error associated with
    the CRO. See State v. Lopez, 
    231 Ariz. 561
    , ¶ 2, 
    298 P.3d 909
    , 910
    (App. 2013). In the sentencing minute entry, the trial court ordered
    “all fines, fees, assessments and/or restitution are reduced to a
    Criminal Restitution Order, with no interest, penalties or collection
    fees to accrue while the defendant is in the Department of
    Corrections.” The trial court’s imposition of the CRO before the
    expiration of Romero’s sentence “‘constitute[d] an illegal sentence,
    which is necessarily fundamental, reversible error.’” Lopez, 
    231 Ariz. 561
    , ¶ 
    2, 298 P.3d at 910
    , quoting State v. Lewandowski, 
    220 Ariz. 531
    ,
    ¶ 15, 
    207 P.3d 784
    , 789 (App. 2009). This remains true even though
    the court ordered the imposition of interest be delayed until after
    Romero’s release. See 
    id. ¶ 5.
    Disposition
    ¶34         For the foregoing reasons, we vacate the CRO but
    otherwise affirm Romero’s convictions and sentences.
    E C K E R S T R O M, Chief Judge, specially concurring:
    ¶35            Although I fully agree with my colleagues’ well-
    reasoned opinion in every other respect, I cannot agree that the trial
    court properly precluded the testimony of the defendant’s expert
    witness. In essence, the trial court ruled that an undisputed expert
    in the scientific field of experimental design was unqualified to
    testify about the experimental design of toolmark comparison
    testing. Given that the state claimed at trial that the toolmark
    comparison evidence demonstrated a match to “a reasonable degree
    of scientific certainty,” Dr. Haber’s proposed testimony was relevant
    and probative to Romero’s defense. Because the majority has
    apparently overlooked the limited scope and nature of Haber’s
    17
    STATE v. ROMERO
    Opinion of the Court
    proffered testimony, it affirms the trial court’s erroneous preclusion
    of that testimony.
    ¶36           I write separately at length because, in supporting that
    ruling, the majority applies an elevated standard for the admission
    of expert testimony at odds with both Rule 702 and controlling
    jurisprudence interpreting that rule. Our supreme court has held:
    (1) the presentation of general expert testimony is admissible to the
    extent it is relevant, reliable, and helpful to the jury, State v. Salazar-
    Mercado, 
    234 Ariz. 590
    , ¶¶ 9-11, 
    325 P.3d 996
    , 999 (2014); (2) a trial
    court’s pretrial conclusion that a purported scientific practice is
    reliable is not binding on the jury, and it invades the province of the
    jury for a court to preclude otherwise admissible evidence
    challenging such reliability, State v. Lehr, 
    201 Ariz. 509
    , ¶¶ 26-29, 
    38 P.3d 1172
    , 1180 (2002); and (3) the comparatively relaxed standards
    for the admission of expert testimony under Rule 702 are not the
    elevated ones set forth, for example, under the common law in the
    area of medical malpractice, Seisinger v. Siebel, 
    220 Ariz. 85
    , ¶¶ 32-35,
    
    203 P.3d 483
    , 492-93 (2009), or those implicitly set forth by the
    Eleventh Circuit in United States v. Paul, 
    175 F.3d 906
    (11th Cir. 1999).
    To the contrary, Rule 702 does not require an expert to have
    qualifications or expertise parallel to those of the opposing party’s
    expert. See Ariz. R. Evid. 702 (expert may be qualified by
    “knowledge, skill, experience, training, or education” to help jury
    understand evidence). Rather, experts need only possess wisdom,
    derived from any of these sources, superior to that of the jury on the
    topic of their testimony. Pincock v. Dupnik, 
    146 Ariz. 91
    , 95, 
    703 P.2d 1240
    , 1244 (App. 1985).
    ¶37          In contradiction of this controlling authority, the
    majority reasons expressly or implicitly that: (1) Dr. Haber’s
    expertise and opinions are too general to be admissible to counter
    the specific conclusions of the state’s firearms identification expert,
    (2) Haber’s experiential qualifications must match or approximate
    those of the state’s expert, (3) a trial court may require an expert to
    possess experiential qualifications even though Rule 702 sets forth
    no such prerequisite and even though the expert’s topic of testimony
    would demand no such experience, and (4) an expert in
    experimental design, who has reviewed all of the studies and
    18
    STATE v. ROMERO
    Opinion of the Court
    literature in the field of toolmark identification, provides a jury with
    no assistance in understanding the limitations, from the standpoint
    of experimental design, of the toolmark evidence before it. Finally,
    the majority leaves undisturbed—and unaddressed—the trial court’s
    erroneous ruling that Haber’s testimony was inadmissible because
    the court had dispositively resolved the reliability of toolmark
    identification evidence during the Daubert hearing, and that ruling
    therefore could not be relitigated before the jury.
    ¶38           As a threshold matter, any assessment of an expert’s
    qualifications must be anchored in the scope of the expert’s
    proffered testimony. See Gaston v. Hunter, 
    121 Ariz. 33
    , 51, 
    588 P.2d 326
    , 344 (App. 1978) (expert must be competent to give expert
    opinion on issue about which he is asked to testify). Here, both the
    trial court and the majority are correct that Dr. Haber has never been
    certified to conduct a toolmark comparison test and has never done
    so himself. However, Romero did not offer Haber to critique
    Powell’s execution of that test but rather for a more general task: to
    question the scientific method underlying such tests, when they
    have been conducted in accordance with the current standards of
    the field.
    ¶39           In presenting his opinions on that point at the Daubert
    hearing, Haber articulated the general features of conventional
    toolmark comparison testing that, in his view, fell short of scientific
    standards for experimental design. He further testified that those
    failings limited the scientific weight that could be placed on the
    results of any such test. As Romero’s counsel clarified, Haber was
    not offered to comment on the facts of the case or to opine whether
    Powell was ultimately “right or wrong.” Although Haber testified
    that he was completely familiar with the extensive literature and
    studies in the field of toolmark analysis and the protocols for such
    testing, Romero did not contend that Haber was qualified to
    challenge whether Powell correctly performed the test of the
    weapon in accordance with the standards of that field. Instead,
    Haber opined that those tests, even if conducted correctly, could not
    scientifically justify the conclusions that the state sought to draw.
    ¶40         Therefore, our task is not to assess whether Dr. Haber
    had the qualifications to opine about the mechanics of conducting a
    19
    STATE v. ROMERO
    Opinion of the Court
    toolmark comparison but rather whether he was qualified to testify
    as to the general scientific limitations of the field. Our supreme
    court has recently held that Rule 702, Ariz. R. Evid., allows an expert
    to offer “general, educative testimony to help the trier of fact
    understand evidence or resolve fact issues.” Salazar-Mercado, 
    234 Ariz. 590
    , ¶ 
    6, 325 P.3d at 998
    . The court explained that nothing in
    Rule 702 “‘alter[s] the venerable practice’ of permitting experts ‘to
    educate the factfinder about general principles.’” Salazar-Mercado,
    
    234 Ariz. 590
    , ¶ 
    9, 325 P.3d at 999
    , quoting Fed. R. Evid. 702 advisory
    committee notes, 2000 amends.
    ¶41           Nor are the standards set forth in Rule 702 for the
    presentation of such testimony either strict or technical. General
    testimony is admissible if “‘(1) the expert [is] qualified; (2) the
    testimony address[es] a subject matter on which the factfinder can
    be assisted by an expert; (3) the testimony [is] reliable; and (4) the
    testimony “fit[s]” the facts of the case.’” Salazar-Mercado, 
    234 Ariz. 590
    , ¶ 
    10, 325 P.3d at 999
    , quoting Fed. R. Evid. 702 advisory
    committee notes, 2000 amends. (alterations in Salazar-Mercado). The
    “‘fit’ pertains to Rule 702(a)’s ‘helpfulness’ standard.” Salazar-
    Mercado, 
    234 Ariz. 590
    , 
    n.1, 325 P.3d at 999
    n.1.
    ¶42          Helpfulness is determined by “‘the common sense
    inquiry whether the untrained layman would be qualified to
    determine intelligently and to the best possible degree the particular
    issue without enlightenment from those having a specialized
    understanding of the subject involved in the dispute.’” Fed. R.
    Evid. 702, advisory committee notes, 1972 proposed rules, quoting
    Ladd, Expert Testimony, 5 Vand. L. Rev. 414, 418 (1952). The
    requirement that evidence be helpful to assist the jury is “‘satisfied
    where expert testimony advances the trier of fact’s understanding to
    any degree.’” United States v. Archuleta, 
    737 F.3d 1287
    , 1297 (10th
    Cir. 2013), quoting 29 Charles Alan Wright & Victor James Gold,
    Federal Practice and Procedure: Evidence § 6265, at 250 (1997).
    Helpfulness is therefore similar to relevance, and it is a low
    threshold to clear. E.E.O.C. v. Boh Bros. Constr. Co.,

    ¶43          In the context of the case before us, Dr. Haber’s
    proffered testimony far exceeded this modest standard. Because the
    20
    STATE v. ROMERO
    Opinion of the Court
    state lacked any eyewitness evidence that Romero was involved in
    the homicide, its case depended on demonstrating Romero’s
    connection to items found or identified at the crime scene. Before
    trial, the state conducted a toolmark analysis on a .40 caliber Glock
    handgun found in Romero’s vicinity a month after the shooting.
    The state’s toolmark expert opined that, based on a visual
    comparison he had conducted of the spent cartridges found at the
    murder scene with those ejected by the Glock handgun during
    testing, the cartridges at the scene could have been fired only by that
    handgun.       At trial, the state elicited, and the state’s expert
    maintained, that such matches reflected “a reasonable degree of
    scientific certainty.”
    ¶44           The defense presented Dr. Haber to challenge the
    validity of this scientific claim. In essence, the defense offered Haber
    to testify that: (1) the general thesis that each handgun leaves a
    unique signature of discernible markings on both cartridges and
    bullets has not yet been scientifically demonstrated; 8 (2) that no
    standards have been developed for determining which types of “tool
    marks” on a cartridge or bullet are relevant to conducting the visual
    comparison, nor have any standards been developed for
    determining how many similarities in markings are necessary to
    conclude that a cartridge or bullet had been fired by a particular
    weapon; (3) that not enough is scientifically documented about the
    8 This conclusion is supported by a recent study of several
    forensic sciences conducted on behalf of the National Academy of
    Sciences.     Nat’l Research Council of the Nat’l Academies,
    Strengthening Forensic Science in the United States: A Path Forward 154
    (2009) (hereinafter “NAS Report”); see also Jennifer L. Mnookin, The
    Courts, the NAS, & the Future of Forensic Science, Brook. L. Rev. 1209,
    1209-10 (2010) (observing that, “[f]or many long-used types of
    forensic science, including fingerprint identification, firearms
    identification,    handwriting      identification,    and     toolmark
    identification, experts’ claims about their field, the authority of their
    methodologies, and their own abilities have dramatically
    outstripped what has actually been established by persuasive
    research and careful study”).
    21
    STATE v. ROMERO
    Opinion of the Court
    similarities or differences between the tool marks left by individual
    guns; and (4) therefore, isolated toolmark comparisons cannot yet
    confidently determine by scientific standards whether a certain
    visual similarity in bullets and cartridges demonstrates a match—or
    merely reflects similarities of make (class) or production batch
    (subclass).
    ¶45          In short, the state’s contention that the fatal bullets
    could only have been fired from a gun later found near Romero was
    significant to its case. Dr. Haber’s testimony would have been
    relevant and therefore helpful to the jury in determining how much
    weight to give the testing evidence marshaled by the state’s expert
    in support of that claim. Notably, neither the state nor the trial court
    appeared to question the relevance of Haber’s proposed testimony.
    Indeed, the court allowed defense counsel to develop the same
    critique of the toolmark identification evidence during cross-
    examination of the state’s expert during trial.
    ¶46          Thus, while there is little dispute that the topic of Dr.
    Haber’s testimony would have been relevant and helpful to the jury,
    the trial court ultimately precluded his testimony on the ground he
    lacked adequate qualifications to so testify. In determining whether
    a witness is adequately qualified to testify, we must be mindful that
    “‘it is not required that the witness have the best possible
    qualifications, nor the highest degree of skill or knowledge, so long
    as [the witness] does have skill and knowledge superior to that of
    [persons] in general.’” 
    Pincock, 146 Ariz. at 95
    , 703 P.2d at 1244,
    quoting 1 Morris K. Udall & Joseph M. Livermore, Arizona Practice:
    Law of Evidence § 22, at 31 (2d ed. 1982). A proposed expert witness
    need not “‘satisfy an overly narrow test of his own qualifications’”
    and is not required to have certificates of training or membership in
    a professional organization. United States v. Barker, 
    553 F.2d 1013
    ,
    1024 (6th Cir. 1977), quoting Gardner v. Gen. Motors Corp., 
    507 F.2d 525
    , 528 (10th Cir. 1974).
    ¶47          Moreover, an expert’s qualifications need not mirror or
    parallel those of the expert whose opinions he or she may challenge.
    To the contrary, Rule 702 contemplates the admissibility of
    conflicting expert testimony “based on competing methodologies.”
    Ariz. R. Evid. 702 cmt. For this reason, the state’s contention that Dr.
    22
    STATE v. ROMERO
    Opinion of the Court
    Haber lacked the qualifications to assist the jury in evaluating the
    reliability of toolmark analysis, simply because he was not a
    practitioner of the methodology used by the state’s expert, finds
    little support in Rule 702 or our jurisprudence interpreting that rule.9
    ¶48           Notably, the state’s toolmark expert, Frank Powell,
    lacked the education, training, and experience to address Dr.
    Haber’s fields of expertise—statistical analysis and experimental
    design. Yet, both Powell and Haber, one qualified primarily by
    experience and practice and the other primarily by education and
    study, were able to provide information “helpful” and relevant to
    the jury in resolving the question before it.
    ¶49         Indeed, the record demonstrates that Dr. Haber had
    acquired ample education, training, and experience to evaluate,
    from the standpoint of scientific method, whether particular
    experiments produce scientifically valid conclusions. He testified
    that he has a Ph.D. in experimental psychology from Stanford
    University, which originally trained him to teach experimental
    design. He taught experimental design for six years at Yale
    University and thereafter for fifteen years at the University of Illinois
    and the University of Rochester.
    ¶50           Notwithstanding the majority’s suggestion that he has
    rarely applied his expertise in scientific design outside the field of
    psychology, he has been trusted by twenty different academic
    journals to conduct peer review of articles in a variety of scientific
    fields as to “experimental designs” and “the interpretations and the
    statistical methods” used to support “the conclusions reached.”
    Organizations that have sought Dr. Haber’s expertise in
    experimental design include the National Science Foundation and
    9Nor  would such a rule be practical. Those experts who are
    skeptical of the scientific status of a practice would not likely
    become trained practitioners of its methodology. An astronomer
    need not be a practitioner of astrology to provide expertise on
    whether the latter field is anchored in scientific principles. And to
    require as much would risk insulating expert opinions from cross-
    disciplinary critique.
    23
    STATE v. ROMERO
    Opinion of the Court
    the National Institute of Health. Since 1994, for two decades, Haber
    has applied that expertise to research conducted in the field of the
    forensic sciences. He has testified numerous times in the area of
    fingerprint comparisons. He has been asked to analyze grant
    applications for the study of forensic sciences by the National
    Institute of Justice (NIJ), the research arm of the U.S. Department of
    Justice. Specifically, the NIJ has asked him to analyze the merits of a
    grant application for research of handgun identification.
    ¶51           He testified that he is “thoroughly familiar” with the
    literature in the field of handgun identification through toolmark
    identification and has written a paper, published in the California
    Bar Journal, on the topic. He likewise testified that he is thoroughly
    familiar with both the methodology and studies in the field of
    firearms identification, including the publications of the NIJ that
    provide guidelines and the most current research. Thus, while Dr.
    Haber is no practitioner of the discipline of toolmark comparisons,
    he is sufficiently learned in its methodologies and protocols to
    usefully apply his undoubted expertise in experimental design to
    that field.10
    10To  counter this point, the majority selectively quotes Haber’s
    testimony that he had “no idea what an examiner does when he
    carries out an examination.” The true meaning of this quotation is
    provided by the sentence immediately preceding it, wherein Haber
    stated, “I can’t talk about the error rate for a method, because there
    is no method that’s described.” In the context of his complete
    testimony, Haber was bluntly emphasizing that an examiner’s
    methodology—namely, “put[ting] the cartridge and the bullet in a
    comparison microscope and look[ing] at them and mak[ing] a
    judgment then of whether they are from the same gun or not”—did
    not amount to a scientific methodology and could not be tested as
    such, because “[e]very examiner must be doing something slightly
    different” and “[h]is conclusions are clearly personal or subjective.”
    Haber was not suggesting he was unfamiliar with the methodology
    and protocol for conducting a toolmark test, as he made abundantly
    clear throughout his testimony.
    24
    STATE v. ROMERO
    Opinion of the Court
    ¶52           In short, Dr. Haber possesses knowledge, education,
    and experience far beyond that of the layperson for analyzing which
    scientific or statistical conclusions may be drawn from a particular
    experimental methodology and which may not. Indeed, he has been
    trusted by numerous scientific journals and our nation’s most
    prestigious scientific foundations to do precisely that in a wide
    variety of fields. And, he has applied that knowledge for many
    years to evaluating various forensic techniques.
    ¶53          The majority’s suggestion that Dr. Haber is little more
    than a psychologist dabbling in a field otherwise alien to him cannot
    be reconciled with the record before us. And, when viewed in light
    of the correct legal standard set forth in Rule 702, which sets a
    modest threshold, the record simply does not support the trial
    court’s conclusion that Haber was unqualified to offer general
    opinions on the scientific reliability of toolmark comparisons based
    on his understanding—which is comprehensive—of the
    experimental design of that methodology. 11 See Villalpando v.
    Reagan, 
    211 Ariz. 305
    , ¶ 6, 
    121 P.3d 172
    , 174 (App. 2005) (abuse of
    discretion occurs when record does not substantially support trial
    court’s decision); see also State v. Chapple, 
    135 Ariz. 281
    , 297 n.18, 
    660 P.2d 1208
    , 1224 n.18 (1983) (trial court abuses discretion in
    precluding expert when reasons given for ruling are clearly
    untenable or unsupported by record). In this context, any arguable
    deficits in Haber’s skill or training would go to the weight of his
    testimony rather than its admissibility—a result Rule 702 specifically
    contemplates. See Ariz. R. Evid. 702 cmt. (“The trial court’s
    11 The trial court’s order demonstrates that she erroneously
    considered any trial dispute about the scientific reliability of
    toolmark comparison evidence to be foreclosed by her Daubert
    ruling. See infra ¶¶ 65-68. Given that Haber’s testimony exclusively
    addressed this very topic, her simultaneous finding—that he lacked
    adequate qualifications to critique Powell’s testimony—might
    merely reflect a narrower, and more accurate, conclusion that he was
    unqualified to address Powell’s execution of the test. But the effect
    of such a determination would be to set appropriate boundaries for
    Haber’s testimony rather than to preclude it altogether.
    25
    STATE v. ROMERO
    Opinion of the Court
    gatekeeping function is not intended to replace the adversary
    system. Cross-examination, presentation of contrary evidence, and
    careful instruction on the burden of proof are the traditional and
    appropriate means of attacking shaky but admissible evidence.”).
    ¶54          Notwithstanding the above record of Dr. Haber’s
    affirmative qualifications, the majority asserts in essence that
    Haber’s general expertise in experimental design does not qualify
    him to analyze the specific scientific method underlying toolmark
    comparison evidence. To support this proposition, the majority cites
    two treatises to support the premise that “[t]he application of
    experimental design principles ‘differ[s] widely from field to field.’”
    Supra ¶ 24, quoting Science 
    Primer, supra, at 1629
    .
    ¶55          But this unassailable premise casts doubt on Dr. Haber’s
    qualifications only if he rendered his opinions in ignorance of it. In
    fact, the record before us demonstrates that Haber exerted himself
    over a period of several years to become comprehensively
    conversant with the “literature,” “methodology,” and “studies” in
    the specific field of forensic toolmark comparisons before offering
    his expertise about the scientific design of that field. The record also
    demonstrates that Haber has spent decades in academia teaching
    experimental design at several of our nation’s most prominent
    universities. We can therefore infer that he understands the most
    basic premises of his own field, is conversant with the “classic
    text[s]” in experimental design, supra ¶ 24, and applied the lessons
    from them here.12 Furthermore, the record shows that Haber has
    been trusted by numerous academic journals to conduct peer
    review, from the standpoint of scientific design, in a variety of
    12  Neither of the treatises articulating the foundations of
    scientific design is found in the record before us. The hazard of
    citing such materials for the first time on appeal, in support of a trial
    court’s finding of fact, becomes apparent here. In essence, the
    majority finds fault with Haber’s qualifications by suggesting that
    his conclusions run afoul of the teachings of academic materials:
    materials that Haber never was presented an opportunity to address
    during trial court proceedings.
    26
    STATE v. ROMERO
    Opinion of the Court
    scientific fields. This, at minimum, demonstrates that these journals
    believe Dr. Haber has broadly applicable expertise.
    ¶56         Finally, our record contains no suggestion that Dr.
    Haber misidentified any scientific principles at play in the toolmark
    field or even that the trial court considered this a factor in
    precluding his testimony. In short, the majority’s claim here—that
    Haber’s testimony could be precluded properly on the ground he
    lacked sufficient sophistication in scientific design to apply that
    wisdom specifically to the toolmark field—finds no foothold in the
    record before us.
    ¶57           I fear the majority not only mischaracterizes Dr. Haber’s
    qualifications in assessing his expertise to testify; it also implicitly
    applies a standard at odds with our state’s rules of evidence in so
    doing. As discussed above, experts are deemed qualified if they
    possess wisdom greater than that of the jury as to the specific topic
    of their testimony. Although superior wisdom may be gained in a
    variety of ways, including by experience and training, see Ariz. R.
    Evid. 702, our supreme court has clarified that mere careful study is
    an equally appropriate method of securing expert qualification. See
    
    Macumber, 112 Ariz. at 570
    , 544 P.2d at 1085 (superior knowledge
    necessary to assist the jury may be based on nothing more than
    “careful study”); see also Ariz. R. Evid. 702 (itemizing “education” as
    a basis for expert qualification).
    ¶58          By that correct standard, the record before us is
    incontrovertible: as to Dr. Haber’s topic—the experimental design
    features of toolmark evidence—Haber has superior knowledge to
    the jury. He is a nationally trusted expert in experimental design
    generally and has applied that wisdom to toolmark evidence
    specifically only after “careful study” of the toolmark comparison
    field.13
    13Indeed, unless some toolmark comparison practitioner exists
    who has become an expert in the field of experimental design, it is
    difficult to conjure an expert more qualified on the topic of Dr.
    Haber’s proffered testimony than Haber himself.
    27
    STATE v. ROMERO
    Opinion of the Court
    ¶59          Rather than assessing Dr. Haber’s expertise by
    evaluating whether he has expertise superior to the jury, the
    approach required by our rules and jurisprudence, the majority
    compares Haber to the mythological perfect witness: the expert in
    experimental design who has also become expert in the experiential
    practice of executing a toolmark comparison. Accordingly, my
    colleagues find fault with Haber’s qualifications because, inter alia,
    he has never been trained as a metallurgist and has never conducted
    a toolmark comparison himself. Supra ¶ 25. 14 While these may
    indeed be qualifications that would make Haber a more perfect
    expert on his topic, and although our supreme court could
    hypothetically erect a rule for expert testimony requiring such
    elevated standards for its admission, my colleagues’ approach is
    simply not the one set forth in our pertinent rules and jurisprudence.
    The majority supports its approach primarily with reference to one
    case from a lone federal circuit, United States v. Paul, 
    175 F.3d 906
    (11th Cir. 1999).15 There, in finding the expert unqualified, the court
    14 The majority also chides Romero for not offering “a
    curriculum vitae, bibliography of published articles, or other record
    of Haber’s experiences and training,” supra ¶ 22, and thereby
    suggests we are presented with an inadequate record of his
    qualifications. But Romero elicited exhaustive testimony from
    Haber under oath demonstrating his pertinent expertise in both
    experimental design and toolmark analysis.             Such testimony
    constitutes a “record.” Moreover, Rule 702 requires no special
    format for the presentation of an expert’s qualifications.
    15The   majority also cites Myers v. Cessna Aircraft Corp., 
    553 P.2d 355
    (Or. 1976), to support precluding Haber’s testimony. But there,
    the Oregon Supreme Court did not affirm the wholesale preclusion
    of the trial testimony of the expert in question. See 
    id. at 369.
    Rather,
    the court merely barred that expert from opining on one topic
    outside his expertise. See 
    id. The witness,
    an expert trained in
    mechanical engineering with some limited experience investigating
    aircraft accidents, was allowed to testify generally about mechanical
    and engineering matters relevant to the airplane crash, but he was
    not permitted to render an opinion on its ultimate cause. 
    Id. at 369-
    70. Here, Haber was never proffered to render an ultimate opinion
    28
    STATE v. ROMERO
    Opinion of the Court
    emphasized the witness’s lack of practical training in conducting
    handwriting analysis and that his only claim to expertise derived
    from having reviewed the literature in the field. 
    Id. at 912.
    By
    contrast, our supreme court has held that an expert may indeed be
    qualified by “careful study” alone, 
    Macumber, 112 Ariz. at 570
    , 544
    P.2d at 1085, and it has promulgated Rule 702 which, by its terms,
    makes no distinctions about the types of expertise necessary to
    demonstrate superior and helpful knowledge to the jury.
    ¶60            Moreover, the Eleventh Circuit supported its rejection
    of study as a basis for expertise by observing that the witness’s
    education as a law professor “did not make him any more qualified
    to testify as an expert . . . than a lay person who read the same
    articles.” 
    Paul, 175 F.3d at 912
    . That conclusion implies that we
    must measure an expert’s qualifications against a hypothetical lay
    person who has reviewed the same literature. Such a standard,
    which is offered without any authority, finds no support in either
    the language or logic of Rule 702. Rule 702 requires an expert to
    possess only such “knowledge, skill, experience, training, or
    education” to “help the trier of fact to understand the evidence.”
    Ariz. R. Evid. 702; see 
    Archuleta, 737 F.3d at 1297
    ; 
    Chapple, 135 Ariz. at 292-93
    , 660 P.2d at 1219-20. And, the Paul reasoning overlooks that
    the trier of fact in a criminal case is almost always a jury—a group of
    laypersons who have most assuredly not reviewed all the literature
    in a pertinent specialized field.16
    about the execution of the toolmark comparison conducted in the
    instant case. For this reason, Myers provides no authority for
    excluding Haber’s general testimony about the scientific design
    underlying toolmark evidence. Rather, Myers suggests such general
    testimony would be admissible, just as the expert there was allowed
    to testify to matters within his general expertise. See 
    id. 16 Moreover,
    my colleagues’ reasoning in finding Paul
    controlling fails to consider that a nationally recognized expert in
    the field of experimental design such as Dr. Haber would read
    toolmark literature with a considerably more sophisticated eye than
    a layperson and therefore be far better equipped to assist the jury in
    understanding it.
    29
    STATE v. ROMERO
    Opinion of the Court
    ¶61           Finally, the miserly approach to assessing expert
    qualifications applied in Paul has not been adopted by other federal
    circuits. The Third Circuit, in United States v. Velasquez, reversed the
    trial court for precluding the very same handwriting analysis expert
    whose qualifications were deemed insufficient in 
    Paul. 64 F.3d at 848
    . In a dramatically different approach to that set forth by the
    Eleventh Circuit, the Third Circuit acknowledged that the proffered
    defense expert had gained specialized knowledge through years of
    study and academic work, 
    id. at 847
    n.4, and, despite the fact that he
    was not a qualified practitioner of the forensic science at issue, 
    id. at 848
    n.6, his general testimony critical of the field was nonetheless
    admissible because it “called into doubt the reliability and
    credibility” of the expert testimony offered by the prosecution and
    would have allowed the jury “to properly weigh th[at] testimony.”
    
    Id. at 848.
    ¶62           In so concluding, the court emphasized both “the
    ‘strong and undeniable preference [in Rule 702, Fed. R. Evid.,] for
    admitting any evidence having some potential for assisting the trier
    of fact’” and the relaxed standard for possessing adequate expertise
    to so testify. 
    Velasquez, 64 F.3d at 849
    , quoting DeLuca v. Merrell Dow
    Pharm., Inc., 
    911 F.2d 941
    , 956 (3d Cir. 1990). As the court observed,
    “‘[w]e have held that a broad range of knowledge, skills, and
    training qualify an expert as such,’ and have ‘eschewed imposing
    overly rigorous requirements of expertise.’” 
    Id., quoting In
    re Paoli
    R.R. Yard PCB Litig., 
    35 F.3d 717
    , 741 (3d Cir. 1994). Indeed, this is
    the approach endorsed by the United States Supreme Court in
    Daubert. 
    See 509 U.S. at 588-89
    (emphasizing “permissive backdrop”
    and “‘liberal thrust’ of the Federal Rules and their ‘general approach
    of relaxing the traditional barriers to opinion testimony’”), quoting
    Beech Aircraft Corp. v. Rainey, 
    488 U.S. 153
    , 169 (1988).
    ¶63          As discussed above, these standards parallel those set
    forth in our own version of Rule 702 and our state’s jurisprudence.
    In conformity with this liberal approach to admitting expert
    testimony, our supreme court has cited Velasquez with approval for
    the proposition that a trial court’s gatekeeping function under
    Rule 702 must not usurp the jury’s exclusive role in deciding the
    weight and credibility of testimony. Lehr, 
    201 Ariz. 509
    , ¶ 27, 38
    30
    STATE v. ROMERO
    Opinion of the Court
    P.3d at 1180. And, although the majority is correct that we owe trial
    courts considerable deference in assessing whether a proffered
    expert is sufficiently qualified to testify, our supreme court has not
    hesitated to reverse trial courts when, as here, the exercise of that
    gatekeeping function usurps the jury’s role in determining the
    appropriate weight to give an expert’s opinion. See 
    id. ¶64 In
    short, the reasoning set forth in Paul is at odds with
    the approach to analyzing expert qualifications adopted by Rule 702
    of the Arizona Rules of Evidence and our controlling jurisprudence.
    Paul’s holding is squarely contradicted by another federal case,
    Velasquez, which has been cited with approval by our own supreme
    court. I therefore cannot agree that we should anchor our reasoning
    in Paul, and I fear that, in so doing, we threaten Arizona’s long held
    preference for trusting juries to assess the comparative credibility of
    those experts who may provide them helpful testimony.
    ¶65          Finally, at the core of the trial court’s decision to
    preclude     Dr.    Haber’s     testimony    was    a    fundamental
    misunderstanding of the appropriate purpose of expert testimony.
    The court precluded Haber’s trial testimony on the grounds that the
    court already had found the methodology and conclusions of the
    state’s expert sufficiently reliable during the Daubert hearing, and
    that the defense was not thereafter allowed to further “challenge an
    evidentiary ruling that’s already been made by the Court.” The
    court further reasoned, “I don’t think that the new rule . . . adopting
    Daubert was anticipating that once the Court applied the rule that an
    expert would come in and challenge the Court’s findings.”
    ¶66           In the closely analogous context of a Frye hearing, our
    supreme court has rejected this very reasoning. Lehr, 
    201 Ariz. 509

    23-30, 38 P.3d at 1179-81

    challenge at trial the reliability of the protocol used by the state’s
    laboratory for DNA testing. 
    Id. ¶¶ 20-23.
    The trial court precluded
    that testimony on the primary ground that the laboratory’s protocol
    “was not within the jury’s province” and that allowing the defense
    to re-litigate the scientific reliability of that protocol before the jury
    would provide an improper “second bite at the apple.”

    STATE v. ROMERO
    Opinion of the Court
    ¶67          Our supreme court reversed and observed that the trial
    court’s reasoning “fails to recognize that very often the same proof
    used to establish admissibility also impacts weight and credibility.”
    
    Id. ¶ 25.
    It then articulated the analytical distinction between the
    respective roles of the trial court and jury as follows:
    A Frye determination is a preliminary
    finding regarding the admissibility of
    scientific     evidence       and      expert
    qualifications. It is the judge who is called
    upon to make this determination. Ariz. R.
    Evid. 104(a). Yet, according to Rule 104(e),
    the judge’s role in determining preliminary
    questions “does not limit the right of a
    party to introduce before the jury evidence
    relevant to weight or credibility.” Ariz. R.
    Evid. 104(e). Implicit in this rule is an
    awareness that some evidence presented at
    the preliminary hearing will also be
    relevant to credibility and weight.
    Otherwise,      Rule 104(e)     would      be
    superfluous.

    .17 It concluded that the trial
    court’s preclusion of the evidence presented at the Frye hearing
    “infringed upon the role of the jury and improperly insulated the
    state’s evidence from critique.” Lehr,

    ¶68          Although the supreme court has adopted new rules for
    the pretrial determination of the admissibility of expert testimony
    since Lehr, see Salazar-Mercado,

    those rules similarly recognize that the threshold Daubert screening
    is not intended to diminish the jury’s role in assessing the reliability

    STATE v. ROMERO
    Opinion of the Court
    of expert testimony. As the Comment to the 2012 Amendment to
    Rule 702 observes:
    The amendment is not intended to
    supplant traditional jury determinations of
    credibility and the weight to be afforded
    otherwise admissible testimony . . . . Cross-
    examination, presentation of contrary
    evidence, and careful instruction on the
    burden of proof are the traditional and
    appropriate means of attacking shaky but
    admissible evidence.
    When the trial court precluded Dr. Haber’s testimony challenging
    the reliability of the state’s evidence on the ground that the court
    had already resolved that question during the Daubert hearing, the
    court overlooked that Haber’s testimony went to the weight and
    credibility of the state’s expert testimony and that its preclusion
    improperly insulated the state’s expert from critique.18 The majority
    mentions this erroneous component of the trial court’s ruling
    without further comment but overlooks that it likely influenced the
    trial court’s skepticism about Haber’s qualifications.
    18This  problem becomes especially pronounced when, as here,
    an experience-based expert makes scientific claims. As noted, the
    state’s expert made scientific claims about the reliability of his
    conclusions. And he specifically disputed on cross-examination that
    no statistical probabilities existed concerning erroneous matches,
    asserting that there had been “several papers written” on the topic
    and that each of them had found the chance of another gun making
    the same identifiable markings to be “astronomical.” This claim
    would have been forcefully rebutted by Haber’s proposed
    testimony. Accord NAS 
    Report, supra, at 153-54
    (“[T]he decision of
    the toolmark examiner remains a subjective decision based on
    unarticulated standards and no statistical foundation for estimation
    of error rates.”). In fact, the state capitalized on the absence of Haber
    in this skirmish, observing in summation that Romero had
    presented “no evidence from this courtroom, from that witness
    stand that actually challenges firearm analysis.”
    33
    STATE v. ROMERO
    Opinion of the Court
    ¶69          In my view, for all the reasons set forth in this
    concurring opinion, the trial court erred in precluding the proffered
    testimony of Dr. Haber. Notwithstanding the relevance of that
    testimony to significant evidence against Romero, I would also
    conclude the trial court’s error was harmless beyond a reasonable
    doubt. Haber’s testimony was brought exclusively to challenge the
    weight the jury could place on Powell’s opinion that only Romero’s
    gun could have fired the fatal shots. But there was other
    circumstantial evidence connecting Romero to the scene of the
    crime. Romero was both connected to a cell phone found at the
    scene and a truck observed leaving it. Given that the gun in
    question was found with the very person otherwise connected to the
    crime by two other items of evidence, the results of Powell’s testing
    rendered the proposition that another gun had fired the bullets
    unlikely in the extreme. Put another way, it would be an
    extraordinary coincidence if a weapon creating such similar
    markings as the murder weapon, but not involved in the murder,
    would happen to be found with Romero. Haber’s testimony—that
    Powell’s methodology could not scientifically exclude every other
    handgun in circulation as having fired the weapon—would not have
    altered that stark fact. I therefore concur in the result affirming
    Romero’s conviction and sentence.
