    MEMORANDUM OPINION AND ACTION ON APPEAL
    BY THE UNITED STATES FILED PURSUANT TO
    ARTICLE 62, UNIFORM CODE OF MILITARY JUSTICE
    ----------------------------------------------------------------------
    HAIGHT, Judge:
    BACKGROUND
    Although the science involved in this government appeal is beyond the ken of
    even relatively experienced jurists, as well as the typical layperson, the facts are
    simple.
    The alleged victim, SLN, reported that appellee raped her. Major (MAJ)
    Henning denied any and all sexual contact with SLN. Genetic material was

    HENNING—ARMY MISC 20150410
    recovered from the underwear SLN wore the evening in question. The Kansas City
    Police Crime Laboratory (KCPCL) conducted deoxyribonucleic acid (DNA) testing
    on that genetic material. After testing and analysis, the KCPCL reported that MAJ
    Henning could not be excluded as a potential minor contributor to the tested sample.
    Furthermore, the KCPCL is of the opinion that approximately 1 in 220 unrelated
    individuals in the general population would be a match to the minor contributor’s
    profile. Major Henning was charged with the rape of, and other sexual crimes
    against, SLN.
    The defense moved to “prohibit the government from offering any expert
    testimony concerning MAJ Henning being a possible contributor of genetic material
    recovered from the underwear of [SLN].” The defense asserted that the DNA
    analysis conducted by the KCPCL and which the government seeks to introduce
    “does not meet the requirements for expert testimony established by [Military Rule
    of Evidence] 702, United States v. Houser [
    36 M.J. 392
    (C.M.A. 1993)], and
    Daubert v. Merrell Dow [Pharms., 
    509 U.S. 579
    (1993)].” After an Article 39(a)
    session, the military judge granted the defense motion and ruled that “[e]vidence
    that [MAJ Henning] is a possible contributor to the genetic material recovered from
    [SLN]’s underwear is excluded.” The government, pursuant to Rule for Courts-
    Martial [hereinafter R.C.M.] 908 and Article 62, UCMJ, appeals the decision of the
    military judge.
    After oral argument and consideration of the government appeal, we find the
    military judge abused his discretion in his ruling to exclude.
    ARTICLE 39(a), UCMJ, HEARING
    For purposes of this motion, the defense called Ms. Jessica Hanna, the
    KCPCL employee who conducted the DNA testing in this case. From a sample
    identified during serological screening of SLN’s underwear, Ms. Hanna extracted
    DNA, amplified and analyzed that DNA, and was able to identify a “major profile”
    from a female as well as a “minor profile” from a male. This minor profile or
    genetic information revealed “five alleles at four different locations [loci].” Major
    Henning’s DNA also has those same five alleles at those same four loci. Therefore,
    he cannot be excluded as a potential contributor. 3 Then, Ms. Hanna applied a
    statistical formula labeled an “alleles present statistic” in order to determine the
    weight of Major Henning’s DNA match or, in other words, the frequency of those in
    the general population with DNA that could possibly match the minor profile. The
    calculated frequency was 1 in 220.
    3
    This is particularly pertinent as, according to KCPCL, the two other males present
    in SLN’s home on the night in question were both excluded after comparison to the
    DNA profile.
    2
    HENNING—ARMY MISC 20150410
    The defense also called Dr. Krane, an expert in the field. While having
    significant concerns with the KCPCL’s calculated ratio of 1 in 220, Dr. Krane
    acknowledged that it was “factually correct” that Major Henning’s genetic
    information does match the minor profile to the extent that the profile only revealed
    five alleles at four loci. In other words, Dr. Krane confirmed that Major Henning’s
    DNA does, in fact, have those same identified five alleles at those four identified
    specific loci. Furthermore, Dr. Krane did not dispute that the minor profile derived
    from the genetic information recovered from the sample found in SLN’s underwear
    accurately reflected the presence of those five alleles at those four loci. Therefore,
    Dr. Krane did not question any of the scientific testing performed or the resulting
    data; his critique dealt with the appropriate statistical significance that should be
    attached to those results.
    Dr. Krane identified various bases for his overall concern. First, the minor
    profile at issue was derived from an exceedingly small amount of DNA. Second,
    similar to the first basis, five points of comparison does not provide much
    information concerning the other points where Henning’s DNA might not match.
    Third, the KCPCL’s “alleles present statistic” assumes allelic dropout, 4 because if
    allelic dropout had not occurred, then Major Henning would effectively be excluded.
    But, Dr. Krane later acknowledged twice that “the less template DNA that you start
    with, the more likely locus dropout and allelic dropout there will be.” Fourth, as the
    statistical analysis was applied to a “minor profile” with low peaks, as opposed to a
    “major profile” with high peaks, the interpretation thereof must not only account for
    allelic dropout and drop-in but also take into consideration “stutter peaks” and how
    those stutters could possibly be allelic peaks of a “minor contributor.” For this
    instance, Dr. Krane testified that the 1 in 220 statistic is “very weak by DNA
    profiling standards . . . but that number would have been less impressive still if
    those stutter peaks had been added into the calculation.” Finally, Dr. Krane is of the
    opinion that in scenarios such as the present, where there is a combination of the two
    factors of “unknown number of contributors” and “possible or assumed allelic
    dropout,” “then all bets are off” and the safer course of action would be to report the
    findings as “inconclusive.”
    Succinctly, when asked what conclusions could be drawn from the results of
    the KCPCL’s DNA testing in this case, Dr. Krane stated:
    What I would prefer to say is that there are essentially
    three ways that one might look at such a circumstance. If
    an individual has two alleles and yet only one is observed
    at that locus in an evidence sample, one might conclude
    that the individual cannot be excluded because dropout
    4
    Allelic dropout is the failure to detect an allele within a sample or failure to
    amplify an allele during the polymerase chain reaction process.
    3
    HENNING—ARMY MISC 20150410
    had occurred. Another is that the individual -- another
    possible conclusion is that the individual is actually
    excluded because dropout did not occur, and a third
    conclusion might be to refrain from drawing a conclusion
    and say that we can’t say if dropout or what the likelihood
    that dropout has or has not occurred is, therefore, since we
    can’t decide which of those two possibilities is most likely
    or how to capture that into some sort of statistic it’s
    simply safest to walk away and say that we don’t care to
    draw a conclusion at all.
    The government called Mr. Scott Hummel, the Chief Criminalist of the DNA
    Biology Section at the KCPCL. In that capacity, he is responsible for quality
    assurance at the lab. Generally, the KCPCL is accredited by the American Society
    of Crime Lab Directors, Laboratory Accreditation Board and is also externally
    audited to ensure its personnel, policies, and procedures are in accordance with the
    Scientific Working Group on DNA Analysis Methods (SWGDAM) guidelines, the
    FBI-issued quality assurance standards, as well as the international standards used
    by the scientific community “not in just this country, but across the world.”
    Specifically, the KCPCL is currently accredited, and all of its “statistical formulas,
    equations, guidelines,” to include the “alleles present statistic,” along with particular
    case files in which such equations were used were provided to and reviewed by the
    accrediting body.
    Mr. Hummel defended the formula used in this case. He explained the
    formula, which accounts for an unknown number of contributors and allelic dropout,
    is a “modification of an unrestricted random match probability” and does not violate
    SWGDAM guidelines. To the contrary, according to Mr. Hummel, this “possible
    permutation or calculation” is actually contemplated by or alluded to in those
    guidelines. Furthermore, Mr. Hummel testified that the KCPCL’s analysis does
    consider and take into account “stutter peaks” and their possible interplay with
    “minor contributor allelic peaks.”
    Dr. Krane was recalled. He was specifically asked if the KCPCL’s formulas
    are “somehow not following the SWGDAM guidelines,” to which he responded, “I
    think it would be best to say I’m saying something a little bit different. I’m saying
    that they’re not being applied appropriately. The formulas in their operating
    procedures and their interpretation guidelines are clearly consistent with and derived
    from the SWGDAM guidelines.”
    THE MILITARY JUDGE’S RULING
    Faced with a classic battle of the experts, the military judge granted the
    defense motion and excluded “[e]vidence that the Accused is a possible contributor
    4
    HENNING—ARMY MISC 20150410
    to the genetic material recovered from Mrs. [SLN]’s underwear.” The military judge
    found, inter alia, as fact:
    1. “The Accused’s DNA matched five alleles at four loci in the minimal
    minor profile from the underwear.”
    2. “SWGDAM is the definitive authority on reliable procedures and methods
    for forensic DNA testing and analysis.”
    3. “The SWGDAM Guidelines are mostly that: guidelines.”
    4. “The Guidelines clearly state that RMP [Random Match Probability
    statistical calculations] and CPE/I [Combined Probability of Exclusion or
    Inclusion statistical calculations] are incompatible with each other.
    5. “KCPCL used a statistical calculation in this case that does precisely what
    the Guidelines state is ‘precluded,’” that is, a combination of RMP and
    CPE/I.
    6. “The amount of human, male DNA used in the testing process in this case
    that resulted in the conclusion that the Accused was included as a potential
    contributor to the genetic material in Mrs. [SLN]’s underwear was the
    equivalent to three or four human cells.”
    7. In accordance with Dr. Krane’s testimony, “because this was an
    exceedingly small quantity,” “because of the possibility of allelic dropout
    or drop-in (e.g., through contamination),” and because this was a minimal
    minor sample, this was “the most difficult sample that could be
    interpreted.”
    8. “Ms. Hanna did not conclude, one way or another, whether allelic dropout
    had occurred in the sample.”
    After reciting the law and standards pertaining to the admission of expert
    testimony and his role as gatekeeper, the military judge then concluded:
    1. “There is no real argument about the first four Houser [
    36 M.J. 392
    ]
    factors in this case: they are satisfied.”
    2. “KCPCL’s testing procedures (i.e., the extraction of DNA from an
    evidentiary sample and the identification therefrom of a constellation of
    specific alleles at specific loci) are not in question; they are reliable under
    a Daubert analysis.”
    3. “However … the ‘modified’ formula KCPCL applied to draw conclusions
    about potential contributors in this case” was not shown to be reliable.
    4. The KCPCL’s “formula has never made it into (much less mentioned by)
    the SWGDAM Guidelines” and “appears wholly contradictory” to the
    guidelines as they “reject KCPCL’s approach.”
    5. The “Guidelines preclude the combination of CPE/I and RMP calculations
    in a given sample.”
    6. An apparent flaw with the KCPCL’s formula is “if you assume two
    contributors to the sample in this case, then the Accused could not have
    5
    HENNING—ARMY MISC 20150410
    contributed all five of the alleles detected; the second person would have
    had to contribute at least one of the alleles (and possibly more). This is
    true regardless whether allelic dropout had occurred.”
    7. The formula the KCPCL used did not rely on a conclusive determination
    whether allelic dropout had occurred.
    8. “This battle of the experts would certainly be a mini-trial within the trial,
    with multiple experts being called and recalled to rebut one another on a
    highly technical issue the panel members will likely have a difficult time
    understanding.”
    9. “Using the 1 in 220 statistic, in a population as small as Weston, Missouri
    (1,641 in the 2010 census (citation omitted)), only 7 people could be
    contributors to the genetic material in Mrs. [SLN]’s underwear.”
    10. Because the “Government is sure to point out that of those seven possible
    people, only one was in Mrs. [SLN]’s house, . . . the probative value is
    substantially outweighed by the danger of unfair prejudice, misleading the
    panel members, and waste of time.”
    LAW AND DISCUSSION
    On appeal, “[w]e review de novo the question of whether the military judge
    properly performed the required gatekeeping function of [Military Rule of Evidence]
    702” and “‘properly followed the Daubert framework.’” United States v. Flesher,
    
    73 M.J. 303
    , 311 (C.A.A.F. 2014) (citing United States v. Griffin, 
    50 M.J. 278
    , 284
    (C.A.A.F. 1999)). However, the decision by the military judge to exclude expert
    testimony is reviewed for an abuse of discretion. United States v. Sanchez, 
    65 M.J. 145
    , 148 (C.A.A.F. 2007). “A military judge abuses his discretion when: (1) the
    findings of fact upon which he predicates his ruling are not supported by the
    evidence of record; (2) if incorrect legal principles were used; or (3) if his
    application of the correct legal principles to the facts is clearly unreasonable.”
    United States v. Ellis, 
    68 M.J. 341
    , 344 (C.A.A.F. 2010). Additionally, “[a]n abuse
    of discretion exists where reasons or rulings of the military judge are clearly
    untenable and . . . deprive a party of a substantial right such as to amount to a denial
    of justice.” United States v. Travers, 
    25 M.J. 61
    , 62 (C.M.A. 1987) (internal
    quotation marks and citations omitted); see also 
    Flesher, 73 M.J. at 311
    . Also,
    because this case came to this court by way of a government appeal under Article 62,
    UCMJ, we are limited to reviewing the military judge’s decision only with respect to
    matters of law and are bound by the military judge’s findings of fact unless they
    were clearly erroneous. We cannot find our own facts or substitute our own
    interpretation of the facts. United States v. Cossio, 
    64 M.J. 254
    , 256 (C.A.A.F.
    2007) (citing United States v. Mizgala, 
    61 M.J. 122
    , 127 (C.A.A.F. 2005)).
    We determine the military judge made two clearly erroneous findings of fact
    as well as multiple erroneous conclusions when applying the law and acting in his
    gatekeeper role.
    6
    HENNING—ARMY MISC 20150410
    Military Judge’s Findings of Fact
    The military judge found, as fact, that the “alleles present statistic” formula
    utilized by the KCPCL is expressly precluded by the SWGDAM guidelines. This
    finding is in error. First, as everybody agreed, to include the military judge, the
    male minor DNA profile was derived from an exceedingly small sample. Page 1 of
    the SWGDAM guidelines reads, “Some aspects of these guidelines may be
    applicable to low level DNA samples.” This prolonged caveat continues, “Due to
    the multiplicity of forensic sample types and the potential complexity of DNA
    typing results, it is impractical and infeasible to cover every aspect of DNA
    interpretation by a preset rule.” In fact, laboratories are encouraged to use their
    professional judgment, expertise, and experience to review their standard operating
    procedures, update their procedures as needed, and utilize written procedures for
    interpretation of analytical results.
    That is precisely what the KCPCL has done. Based upon its collective
    expertise and judgment and in accordance with SWGDAM guidelines, it has
    incorporated in its DNA Analytical Procedure Manual an “alleles present statistic.”
    This formula “accounts for allelic drop-out and makes no assumption regarding the
    number of contributors.” 5
    The aforementioned formula has been used by the KCPCL for 15 years, and
    the KCPCL, along with its manuals, procedures, and written methods of statistical
    calculations, has been audited and inspected “about ten different times” to ensure it
    is not running afoul of the SWGDAM guidelines or the FBI’s Quality Assurance
    Standards for Forensic DNA Testing Laboratories. Finally, paragraph 4.1 of the
    SWGDAM guidelines mandates, “The laboratory must perform statistical analysis in
    support of any inclusion that is determined to be relevant in the context of a case,
    irrespective of the number of alleles detected and the quantitative value of the
    statistical analysis.” The KCPCL did not mix preset and firm RMP and CPE/I
    formulae. It modified an RMP calculation in accordance with their assumptions, as
    is its scientific prerogative. Other scientists may feel it “safer” to do otherwise, but
    that does not mean the formula is expressly forbidden by the applicable guidelines.
    The military judge also found, “Ms. Hanna did not conclude, one way or
    another, whether allelic dropout had occurred in the sample.” This finding and its
    corresponding conclusion are clearly erroneous and unsupported by the record.
    When statistically analyzing the minor profile, the KCPCL assumed allelic dropout
    and then necessarily concluded that this dropout occurred when reporting the
    frequency ratio. Both of the witnesses from the KCPCL testified clearly and
    repeatedly that the “alleles present statistic” accounts for allelic dropout and is
    5
    The “alleles present statistic” is the calculation of the alleles present at each
    genetic location accounting for possible drop-out of the sister allele in a genotype.
    7
    HENNING—ARMY MISC 20150410
    utilized in those scenarios where allelic dropout is assumed. In fact, one of Dr.
    Krane’s main criticisms of the KCPCL’s analysis in this case is that it was premised
    upon the assumption and conclusion that allelic dropout had, in fact, occurred. Dr.
    Krane explained that “[Ms. Hanna]’s statistic is predicated on the fact that dropout
    did occur. Her inclusion of Major Henning as a possible contributor is predicated on
    the idea that dropout must have occurred. . . . If dropout had not occurred . . . then
    Major Henning is actually excluded as a possible contributor.”
    Military Judge’s Conclusions of Law
    The military judge concluded the government had not shown the statistical
    evaluation applied by the KCPCL in this case to be “reliable.” In determining that
    the military judge abused his discretion in so concluding, we do not do so lightly.
    We may not apply a review more “stringent” than abuse of discretion to a trial
    court’s decision to receive or exclude evidence and similarly may not reverse unless
    the trial ruling was “manifestly erroneous.” GE v. Joiner, 
    522 U.S. 136
    , 142-43
    (1997). Likewise, we acknowledge a “court of appeals applying ‘abuse of
    discretion’ review to such rulings may not categorically distinguish between rulings
    allowing expert testimony and rulings which disallow it,” nor was the military judge
    required “to admit opinion evidence which is connected to existing data only by the
    ipse dixit of the expert.” 
    Id. at 142,
    146. That said, we find the military judge’s
    exclusion of any and all evidence that MAJ Henning is a possible contributor to the
    genetic material recovered from SLN’s underwear was manifestly erroneous.
    In this case, both parties present experts who agree on the underlying science
    of DNA extraction, matching, and comparison and also agree on the underlying data
    that was generated, that is, five alleles present at four loci. They disagree, however,
    on what is to be concluded from that data. Daubert is clear:
    The inquiry envisioned by [Federal Rule of Evidence] 702
    is, we emphasize, a flexible one. Its overarching subject
    is the scientific validity -- and thus the evidentiary
    relevance and reliability -- of the principles that underlie a
    proposed submission. The focus, of course, must be solely
    on principles and methodology, not on the conclusions
    that they generate.
    
    Daubert, 509 U.S. at 594-95
    . The proffered frequency ratio of 1 in 220 is not
    connected to the presence of those specific five alleles at those specific four loci by
    the ipse dixit of Ms. Hanna; rather, it is connected by a long-used, reproducible,
    announced, audited, and written formula.
    In excluding evidence of the statistical significance of the matching minor
    profile, the military judge expressly adopted Dr. Krane’s conclusion that this would
    8
    HENNING—ARMY MISC 20150410
    be attaching weight to an “exceedingly small quantity” and is “the most difficult
    sample that could be interpreted.” Dr. Krane did not testify that no conclusions
    could be drawn from the minor profile; he testified it would be “safer” to not draw
    any conclusions from such a profile. Our superior court has addressed a scenario
    where experts in the field differ in their interpretation of the underlying facts and
    how much weight, if any, should be given to those facts in deriving an opinion. See
    
    Sanchez, 65 M.J. at 151
    . In that case, it is made clear that any requirement that
    experts agree on a certain interpretation “would be at odds with the liberal
    admissibility standards of the federal [and military] rules and the express teachings
    of Daubert.” 
    Id. at 152
    (quoting Amorgianos v. Amtrak, 
    303 F.3d 256
    , 267 (2d. Cir.
    2002)). Furthermore,
    A review of the caselaw after Daubert shows that the
    rejection of expert testimony is the exception rather than
    the rule . . . . The trial court’s role as gatekeeper is not
    intended to serve as a replacement for the adversary
    system. As the Court in Daubert stated: “Vigorous 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.”
    United States v. Billings, 
    61 M.J. 163
    , 169 (C.A.A.F. 2005) (citation omitted). At
    worst, the KCPCL’s approach was shaky science; it was definitely not junk science
    and should not be excluded. See 
    Sanchez, 65 M.J. at 153
    (citing Kumho Tire Co. v.
    Carmichael, 
    526 U.S. 137
    , 152 (1999)).
    A trial judge certainly can and should form an opinion as to the reliability of
    differing scientific approaches when performing his role as gatekeeper. However,
    here, the military judge overstepped his bounds and conducted his own scientific
    analysis and statistical evaluation. In the “Conclusions” portion of his ruling, the
    military judge points out his perceived flaws in the KCPCL’s formula and then
    proceeds to discuss the possibilities of heterozygous or homozygous alleles at
    various loci and how those eventualities would potentially impact the appropriate
    statistical approach. The problem lies in his statement, “First, if you assume two
    contributors to the sample in this case, then the Accused could not have contributed
    all five of the alleles detected; the second person would have had to contribute at
    least one of the alleles (and possibly more). This is true regardless whether allelic
    dropout had occurred.” Not only do we question the scientific and mathematical
    validity of the above statement, it is wholly unsupported in the record. None of the
    experts testified consistent with the military judge’s base premise. Accordingly, we
    are left with the distinct impression that in this battle of the experts, the military
    judge became his own expert, conducted his own analysis of the evidentiary DNA
    data and application of the SWGDAM guidelines in a manner not addressed by any
    9
    HENNING—ARMY MISC 20150410
    of the experts, and consequently impermissibly assumed a role far different than that
    of gatekeeper.
    In the same portion of his ruling, the military judge criticized the government
    for providing “no evidence of error rates with regard to KCPCL’s formula or what
    the statistical cutoff is for inclusion as a possible contributor (e.g., is 1 in 100,000 a
    permissible statistic to be included?).” Regardless of the obvious observations that a
    pure numerical cutoff line would, by definition, go to the weight of a factual finding
    as opposed to its validity or admissibility and that a statistical cutoff is a distinct
    concept from an error rate, we again look to Sanchez. “Nothing in the precedents of
    the Supreme Court or this Court requires that a military judge either exclude or
    admit expert testimony because it is based in part on an interpretation of facts for
    which there is no known error rate or where experts in the field differ in whether to
    give, and if so how much, weight to a particular fact.” 
    Sanchez, 65 M.J. at 151
    .
    We now turn to the military judge’s Military Rule of Evidence 403 balancing
    in which he found the probative value of the KCPCL’s “statistical conclusion” is
    “substantially outweighed by the danger of unfair prejudice, misleading the panel
    members, and waste of time.” We find three parts of his balancing to be manifestly
    erroneous.
    First, the military judge found the probative value of the statistical
    conclusion, the 1 in 220 ratio, to be minimal. There is a disconnect between the
    concerns the military judge harbored with respect to the reliability of the KCPCL’s
    formula and his blanket exclusion of evidence that MAJ Henning is a possible
    contributor to the discovered genetic material. In accordance with the options found
    in the SWGDAM guidelines and in line with Dr. Krane’s suggestion, the most
    favorable conclusion the defense could have hoped for was that comparison of MAJ
    Henning’s DNA to the minor profile was either inconclusive or uninterpretable.
    But, even in that event, because per SWGDAM, “statistical analysis is not required
    for exclusionary conclusions,” that would still potentially leave evidence that the
    other males in the house that night in question are excluded as contributors to the
    male minor profile found in SLN’s underwear. In other words, in this case, the
    importance of the numerical ratio may be relatively minimal. But, in light of the
    categorical exclusion of other potential suspects, any evidence that MAJ Henning is
    a possible contributor, even to a small degree, would still be highly probative.
    Second, the military judge concludes this “battle of the experts would
    certainly be a mini-trial within the trial, with multiple experts called and recalled to
    rebut one another on a highly technical issue the panel members will likely have a
    difficult time understanding.” We echo the Supreme Court in that this view “seems
    to us to be overly pessimistic about the capabilities of the jury and of the adversary
    system generally. Vigorous 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.” 
    Daubert, 509 U.S. at 596
    . The
    questions of whether SLN was assaulted and by whom do not constitute the subjects
    of any “mini-trial;” rather, they are the very essence of the trial.
    Third, inconsistent with his prior conclusion that the probative value of the
    KCPCL’s “resulting statistical conclusion” is minimal, the military judge then
    applied the 1 in 220 ratio against the population of the city where the alleged crime
    occurred and concluded that his calculation that only seven people in that city could
    be contributors is a significant and unfairly prejudicial statistic. The military judge
    observed, “The Government is sure to point out that of those seven possible people,
    only one was in Mrs. [SLN]’s house.” In this case, we find that evidence that an
    accused’s DNA possibly matches that of genetic material found at the scene of the
    alleged crime to indeed be prejudicial, but not even remotely unfairly so. Once a
    proper foundation is laid, not only is DNA testing sufficiently reliable and
    admissible, but evidence of statistical probabilities of an alleged match is admissible
    as well. See United States v. Allison, 
    63 M.J. 365
    (C.A.A.F. 2006).
    CONCLUSION
    “The military judge’s role as evidentiary gatekeeper does not require him to
    admit only evidence that he personally finds correct and persuasive and to exclude
    that which he finds incorrect or unpersuasive. Rather, the judge’s role is to screen
    all evidence for minimum standards of admissibility and to let the factfinder
    determine which evidence is more persuasive.” United States v. Kaspers, 
    47 M.J. 176
    , 178 (C.A.A.F. 1997). We possess, as a reviewing court, “a definite and firm
    conviction that the [military judge] committed a clear error of judgment in the
    conclusion [he] reached upon a weighing of the relevant factors” and thus find an
    abuse of discretion. See

    Law Journal at 4, col. 2 (March 1, 1962), quoted in Quote It II: A Dictionary of
    Memorable Legal Quotations 2 (1988)).
    The appeal of the United States pursuant to Article 62, UCMJ, is granted.
    The ruling of the military judge to exclude evidence that MAJ Henning is a possible
    contributor to the genetic material recovered from SLN’s underwear on the bases
    that the KCPCL’s formula and its application in this case are unreliable and unfairly
    prejudicial is set aside. The record will be returned to the military judge for action
    not inconsistent with this opinion
    Senior Judge COOK and Judge WEIS concur.
