We hold that the district court did not err on either Accordingly, we affirm the convictions and sentences. BACKGROUND On a gelid night in February 1996, residents along the 1100 block of Sperling Drive, a residential street in Wilkinsburg, Pennsylvania, were startled by the ringing sound of gun shots. One resident who rushed to see what had happened saw two people shooting into a Ford Bronco parked alongside the street. Another

observed a mid-sized car darting away from the scene immediately after the shooting ceased. shooters in detail. Once the commotion passed, one of the residents approached the Ford Bronco. Inside she found the bullet-riddled bodies of Law enforcement was But neither was able to describe the

called, a crime scene was established, and an investigation immediately ensued. The indictments that followed charged appellants with operating a violent criminal organization that existed for the purpose of, among other things, enriching its members by trafficking in cocaine and cocaine base in New York and Pennsylvania. Because the government sought the death penalty

against Bobby and Michael for their roles in the triple homicide,

they were tried separately from Xavier on a superceding indictment that charged fifteen counts: racketeering, in violation of 18 U.S.C. § 1962(c) (Count One); racketeering conspiracy, in violation of 18 U.S.C. § 1962(d) (Count Two); conspiracy to murder in aid of racketeering activity, in violation of 18 U.S.C. § 1959(a)(5) (Counts Three and Four); murder in aid of racketeering activity, in violation of 18 U.S.C. §§ 2, 1959 (a)(1) (Counts Five through Seven); conspiracy to distribute narcotics, in violation of 21 U.S.C. § 846 (Count Eight); murder while engaged in a narcotics conspiracy, in violation of 18 U.S.C. § 2 and 21 U.S.C. § 848(e) (Counts Nine through Eleven); use of a firearm during and in relation to a drug trafficking crime or crime of violence, in violation of 18 U.S.C. §§ 2, 924(j) (Counts Twelve through Fourteen); and conspiracy to launder money derived from narcotics trafficking, in violation of 18 U.S.C. § 1956(h) (Count Fifteen). The jury

found Bobby and Michael guilty on all counts except Counts Three and Four but determined that they should not receive the death penalty. Bobby and Michael were sentenced principally to life

imprisonment. Xavier was tried on a superceding indictment charging fourteen counts that matched Bobby's and Michael's indictment through Count Thirteen, omitted one of the firearm counts, and charged the money laundering count as Count Fourteen instead of

Fifteen.

Upon the government's motion, the district court

dismissed Counts Five, Six, Seven, Nine, Ten, Eleven, and Twelve. The jury found Xavier guilty on all remaining counts except Count Four. He was sentenced principally to life imprisonment.

The remaining facts and procedural history are provided as necessary for our analysis of the specific issues addressed in this opinion. DISCUSSION I. Admission of Bobby's Out-of-Court Statements Prior to the trial of Bobby and Michael, the government requested permission to introduce, against both defendants, statements Bobby made to Carol Johnson, Earl Baldwin, and Julian Brown about his involvement in the triple homicide. Michael

objected and moved for exclusion and, in the alternative, requested a severance pursuant to Fed. R. Crim. P. 14. After

hearing from both sides, the district court denied the severance and allowed Johnson and Baldwin, but not Brown, to testify about Bobby's statements, finding their testimony admissible under the exception to the hearsay rule for statements against penal interest. See Fed. R. Evid. 804(b)(3). The district court also

found no Confrontation Clause impediment to the admission of Johnson's and Baldwin's testimony. At trial, Baldwin testified that Bobby admitted to him on two separate occasions that he participated in the triple

homicide.

Bobby first told Baldwin that Timothy Moore was killed The second time, Bobby, speaking

because the "Dude owed" money.

about himself and Michael, stated: "[W]e gave it to them niggers. . . . [W]e walked up to the truck, each of us on a side of the truck and gave it to them niggers." Johnson, echoing much of

Baldwin's account, testified that Bobby told her that the victims were shot because of their debts. She then explained that Bobby

told her that Michael shot the man in the driver's seat while Bobby shot at least one of the other passengers. Johnson's

testimony did not account for the shooting of the third victim. In this challenge to the district court's pretrial ruling, Michael argues again that the admission of Bobby's out-of-court statements violated both Rule 804(b)(3) and the Confrontation Clause. We review the district court's admissibility

determination under Rule 804(b)(3) for abuse of discretion and its Confrontation Clause analysis de novo. Tropeano, 252 F.3d 653, 657 (2d Cir. 2001). A. Admissibility under Rule 804(b)(3) United States v.

Admission of a statement under Rule 804(b)(3) hinges on "whether the statement was sufficiently against the declarant's penal interest `that a reasonable person in the declarant's position would not have made the statement unless believing it to be true.'" Williamson v. United States, 512 U.S. 594, 603-04 Whether a challenged statement

made on a case-by-case basis.

We find no abuse of discretion in the district court's decision to admit the challenged statements under Rule 804(b)(3). The first of Bobby's statements to Baldwin was plainly selfinculpatory, and it did not on its face implicate Michael. second of Bobby's statements to Baldwin and his statement to Johnson were also sufficiently self-inculpatory as they described acts that he and Michael committed jointly. See United States v. The

Saget, 377 F.3d 223, 231 (2d Cir. 2004) (finding that the bulk of confessor's statements were self-inculpatory because they described acts that the defendant and the confessor committed jointly). Moreover, the context of these statements shows that

Bobby was not attempting to minimize his own culpability, shift blame onto Michael, or curry favor with authorities. Williamson, 512 U.S. at 601, 603. Cf.

To the contrary, in his second

statement to Baldwin, Bobby was boastful regarding his participation in the murders, and in his remark to Johnson he claimed an equal role, asserting that he and Michael each killed one of the three victims. B. Confrontation Clause Analysis

The Confrontation Clause states that "[i]n all criminal prosecutions, the accused shall enjoy the right . . . to be

confronted with the witnesses against him." VI.

U.S. Const. amend.

In Crawford v. Washington, 541 U.S. 36 (2004), the Supreme

Court held that the Confrontation Clause prohibits the admission of out-of-court "testimonial" statements against a criminal defendant, unless the declarant is unavailable and the defendant had a prior opportunity to cross-examine the declarant. Crawford's per se bar on such testimonial statements displaced that much of the "indicia of reliability" standard of Ohio v. Roberts, 448 U.S. 56 (1980), that had allowed into evidence, as not violative of the Confrontation Clause, hearsay statements that fell within a firmly rooted hearsay exception or contained particularized guarantees of trustworthiness. Id. at 66;

Crawford, 541 U.S. at 60; Saget, 377 F.3d at 226 (explaining that under Roberts, "[a]ny out-of-court statement was constitutionally admissible so long as it fell within an exception to the hearsay rule or, if that exception was not firmly rooted, the court found that the statement was likely to be reliable"). While Crawford's per se bar did away with Roberts' reliability analysis for testimonial statements, it left unclear whether the admission of "nontestimonial" statements would still implicate Confrontation Clause concerns because Crawford did not explicitly overrule Roberts on that score. See Saget, 377 F.3d

at 227 ("Crawford leaves the Roberts approach untouched with respect to nontestimonial statements. . . . Accordingly, while 8

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29

the continued viability of Roberts with respect to nontestimonial statements is in doubt, we will assume for purposes of this opinion that its reliability analysis continues to apply to control nontestimonial hearsay . . . ."). However, in Davis v.

Washington, 126 S. Ct. 2266 (2006), the Court was required to "decide . . . whether the Confrontation Clause applies only to testimonial hearsay." Id. at 2274 (emphasis added). Answering

that question in the affirmative, the Court explained that Crawford, even if it did not expressly so hold, pointed the way: The text of the Confrontation Clause reflects this focus on testimonial hearsay. It applies to witnesses against the accused -- in other words, those who bear testimony. Testimony, in turn, is typically a solemn declaration or affirmation made for the purpose of establishing or proving some fact. An accuser who makes a formal statement to government officers bears testimony in a sense that a person who makes a casual remark to an acquaintance does not. Id. "A limitation so clearly reflected in the text of the

constitutional provision," the Court continued, "must fairly be said to mark out not merely its `core,' but its perimeter." Id.

Following Davis, we stated in United States v. Feliz, 467 F.3d 227 (2d Cir. 2006), that Roberts' reliability analysis plays no role in a Confrontation Clause inquiry. See id. at 230-32.

It is plain from Davis "that the right to confrontation only extends to testimonial statements, or, put differently, the Confrontation Clause simply has no application to nontestimonial statements." Feliz, 467 F.3d at 231; see Tom Lininger,

9

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29

Reconceptualizing Confrontation After Davis, 85 Tex. L. Rev. 271, 280 (2006) ("Whereas Crawford called into question the reasoning of Roberts, Davis sounded the death knell. The Davis Court

indicated plainly that the protections of the Confrontation Clause are limited to testimonial hearsay."). Now, after Crawford and Davis, indicia of reliability play no role in the Confrontation Clause analysis. Rather, the inquiry under the Confrontation Clause is whether the statement at issue is testimonial. If so, the Confrontation Clause requirements of unavailability and prior cross-examination apply. If not, the Confrontation Clause poses no bar to the statement's admission. Feliz, 467 F.3d at 232. Michael does not, nor could he, contend that Bobby's statements were testimonial; they bear none of the hallmarks of testimonial statements identified in Crawford. See 541 U.S. at

51-52 (identifying as testimonial "ex parte in-court testimony," "extrajudicial statements . . . contained in formalized testimonial materials, such as affidavits, depositions, prior testimony, or confessions," and "statements that were made under circumstances which would lead an objective witness reasonably to believe that the statement would be available for use at a later trial" (internal quotation marks and citations omitted)); see also Saget, 377 F.3d at 228 (identifying as testimonial under Crawford "a declarant's knowing responses to structured questioning in an investigative environment or in a courtroom setting where the declarant would reasonably expect that his or 10

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24

her responses might be used in future judicial proceedings"). Instead, relying on Roberts and its progeny, Michael asserts that the statements lack particularized guarantees of trustworthiness. Because the Confrontation Clause does not bar such nontestimonial statements, whatever their guarantees of trustworthiness, Michael's argument fails and our Confrontation Clause inquiry is at an end. * * * Accordingly, we conclude that the district court neither abused its discretion in admitting Bobby's out-of-court statements under Rule 804(b)(3) nor violated the Confrontation Clause in doing so. II. The Government's Firearms Identification Expert Spent bullets, cartridge casings, and bullet fragments were recovered from the scene of the triple homicide and the victims' bodies. A subsequent search of Michael's apartment in

Pittsburgh, Pennsylvania turned up two handguns, one of which was a 9mm Bryco semiautomatic pistol. Shortly thereafter, this and

other ballistics evidence was turned over to Michelle Kuehner, a firearms examiner in the Forensic Laboratory Division of the Allegheny County Coroner's Office (the "Forensic Lab"). Upon

comparing the ballistics evidence recovered from the crime scene and the victims' bodies with bullets and cartridge casings produced from a test firing of the 9mm Bryco, Kuehner concluded

there was a "match."1 Before trial, the government placed Bobby and Michael on notice that it intended to call Kuehner as an expert witness. Michael moved for a pretrial Daubert hearing to challenge Kuehner's testimony,2 contending that the government had yet to establish its admissibility under Fed. R. Evid. 702. In an order dated December 22, 2004, the district court denied the motion without a hearing. It reasoned:

Judge Marrero of this Court has recently upheld the use of ballistics as reliable under Rule 702. See United States v. Santiago, 199 F. Supp. 2d 101, 111-12 (S.D.N.Y. 2002). The Supreme Court has likewise cited ballistics as a proper subject of expert testimony because it aids the jury in understanding the evidence. See United States v. Scheffer, 523 U.S. 303, 312-313 (1998) ("unlike expert witnesses who testify about factual matters outside the juror's knowledge, such as the analysis of fingerprints, ballistics, or DNA found at a crime scene, a polygraph expert can supply the jury only with another opinion, in addition to its own, about whether the witness was telling the truth"); see also United States v. Foster, 300 F. Supp. 2d 375, 376 n.1 (D. Md. 2004) (stating that, "[i]n the years since Daubert, numerous cases have confirmed the reliability of ballistics identification," and collecting cases); [United States v. O'Driscoll, No. 4:CR-10-277, 2003 WL 1402040, at *2 (M.D. Pa. Feb. 10, 2003)] ("the field of ballistics is a proper subject for expert testimony and
1

Apparently Bobby's and Michael's own firearms examiner came to the same conclusion as Kuehner.
2

Though Bobby raises the issue on appeal and the parties indicate that he was the one who requested a Daubert hearing, the district court's order states that it was, in fact, Michael who made the request. United States v. Williams, No. S100CR.1008(NRB), 2004 WL 2980027, at *24 (S.D.N.Y. Dec. 22, 2004). This is of no moment, however, because appellants have joined one another's arguments pursuant to Fed. R. App. P. 28(i). 12

meets the requirements of Rule 702."). . . . Defendants have not offered any reason for us to depart from the reasoning of these cases. Accordingly, the request for a Daubert hearing to challenge the government's proposed ballistics . . . evidence is denied. Williams, 2004 WL 2980027, at *24. At trial, the government called Kuehner as an expert. testified first about her background. She

Kuehner stated that she

had served as a firearms examiner within the firearms section of the Forensic Lab for approximately twelve years. She testified

that, in addition to the "hands-on training" she received from her section supervisor, Dr. Robert Levine, she attended seminars on firearms identification, including annual workshops put on by the Association of Firearm and Toolmark Examiners (the "AFTE") where firearms examiners from the United States and the international community gather to present papers on current topics within the field. Kuehner also explained that she and Dr.

Levine published a paper in the AFTE Journal matching a bullet to the cartridge case from which it was discharged. Kuehner further

stated that she has given presentations on the subject of firearms analysis at several AFTE meetings and for Duquesne University's forensic science and law programs. In addition,

Kuehner testified that she had examined approximately 2,800 different types of firearms and provided expert testimony on between 20 and 30 occasions. After establishing her background, training, and experience, 13

1 2 3 4 5 6 7 8 9 10 11 12 13

Kuehner went on to testify that she uses a firearms identification methodology that is a subset of a broader forensic discipline referred to as toolmark identification. Toolmark

examiners are trained to examine the marks left by tools on a variety of surfaces in an attempt to "match" a toolmark to the particular tool that made it. Firearms, she explained, are

simply the tools that impart marks on bullets and cartridge cases.3 Kuehner then testified as to how the methodology enables her to determine whether a given sample of ballistics components4 was fired from the same gun. "class characteristics." She starts by examining the components' A spent bullet's class characteristics

include its caliber, the number of its land and groove

The ballistics components relevant here include the spent bullets and cartridge casings recovered from the crime scene and the victims' bodies. It suffices for our analysis to recount Kuehner's testimony regarding the process by which she examines spent bullets, but we note that the process she employs in examining spent cartridge cases involves many of the same concepts. 14

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19

impressions,5 the twist of its land and groove impressions, and the width of its land and groove impressions. Class

characteristics, Kuehner explained, allow her to narrow the universe of firearm possibilities to certain types of guns made by certain manufacturers. For example, a spent 9mm bullet

exhibiting six land and groove impressions could only have been expelled from a firearm with a 9mm gun barrel that has six lands and grooves. Once Kuehner narrows the firearms possibilities by class, she looks for specific random, microscopic imperfections in the barrel caused by changes in the manufacturing tool as it makes each barrel on the production line. These imperfections in turn

leave unique "striations" on each bullet as it moves through the barrel. It is her examination of these unique marks, Kuehner

testified, that allows her to determine whether two bullets were fired from the same gun. Using a comparison microscope to view the two bullets sideby-side, she compares the height, depth, width, length and spatial relations of their striations. Significant similarity

1 2 3 4 5 6 7 8 9

When a handgun is fired, its barrel imparts "rifling" on the bullet. Rifling places a twist on a bullet as it travels, thus promoting flight accuracy. Rifling, which runs the length of the barrel, consists of cuts called "grooves" and raised surfaces called "lands." As a bullet travels down the barrel, the raised lands press into the surface of the bullet and it likewise conforms to fill the recessed grooves. The corresponding marks left on the bullet are referred to as land and groove impressions. 15

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32

between striations signals an "identification" or a "match" -- that is, the bullets were fired from the same firearm. striations need not be identical; they need only be in "sufficient agreement" based on Kuehner`s training and experience. She explained: The

So I am looking at the number of striations, . . . their physical characteristics, their height, [and] their depth. And when the pattern of agreement exceeds the amount of agreement that I know exists in two bullets that have not been fired from the same firearm, then that is sufficient agreement. * * * You can't really put numbers to it. It's more, more coming from experience, so, which is why . . . you test bullets. So sufficient agreement meaning that you have enough agreement [between the striations on the bullets] than those that you know do not match. Kuehner testified that, based on comparison of striations, there are two conclusions she may reach other than a match. She

can make an "eliminat[ion]," concluding that the two bullets were not fired from the same gun. Or, she can make an "inconclusive"

determination, meaning that, although the bullets exhibit similar class characteristics, there is not enough agreement or disagreement between their striations to conclude whether they were or were not fired from the same gun. Kuehner further

explained that after she performs her examination, she documents her conclusions in a report, which Dr. Levine reviews. Based on

her analysis in this case, Kuehner concluded that certain bullets and cartridge casings recovered from the crime scene and the 16

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18

victims' bodies matched those she produced by test firing the 9mm Bryco. Bobby now challenges the district court's decision to permit Kuehner to testify as an expert. We understand his

argument to be that the district court abused its discretion by (1) denying him a Daubert hearing and (2) failing to undertake an adequate inquiry into the reliability of Kuehner's firearms identification methodology. The government counters that the

district court acted within its discretion under the circumstances and that any error was harmless.6 We review the

district court's decision to admit expert testimony under Rule 702 for abuse of discretion. U.S. 137, 152 (1999). Kumho Tire Co. v. Carmichael, 526

"A decision to admit scientific evidence

is not an abuse of discretion unless it is manifestly erroneous." United States v. Salameh, 152 F.3d 88, 129 (2d Cir. 1998) (internal quotation marks omitted). A. Gatekeeping under Daubert

While the proponent of expert testimony has the burden of

6

The government also contends that Bobby failed to preserve his claim of error as to the reliability of Kuehner's testimony because his pretrial challenge lacked the necessary specificity, which was never remedied by a further objection after Kuehner's trial testimony provided more persuasive grounds for objection. Therefore, the government argues that the district court's decision should be reviewed for plain error only. But we need not reach this point because we conclude that Bobby cannot satisfy the lower burden of abuse of discretion according to the record here. 17

establishing by a preponderance of the evidence that the admissibility requirements of Rule 702 are satisfied, see Daubert, 509 U.S. at 593 n.10, the district court is the ultimate "gatekeeper." See Fed. R. Evid. 104(a); United States v. Cruz,

363 F.3d 187, 192 (2d Cir. 2004); see also Brooks v. Outboard Marine Corp., 234 F.3d 89, 91 (2d Cir. 2000) (rejecting argument that opposing expert testimony is necessary to trigger the district court's obligation to analyze admissibility of expert testimony). The Federal Rules of Evidence assign to it "the task

of ensuring that an expert's testimony both rests on a reliable foundation and is relevant to the task at hand." U.S. at 597. In assessing reliability, "the district court should consider the indicia of reliability identified in Rule 702, namely, (1) that the testimony is grounded on sufficient facts or data; (2) that the testimony is the product of reliable principles and methods; and (3) that the witness has applied the principles and methods reliably to the facts of the case."

be tested; (2) "whether the theory or technique has been subjected to peer review and publication;" (3) the technique's "known or potential rate of error" and "the existence and maintenance of standards controlling the technique's operation;" and (4) whether a particular technique or theory has gained general acceptance in the relevant scientific community. Daubert, 509 U.S. at 593-94. "Daubert's list of specific factors," however, "neither necessarily nor exclusively applies to all experts or in every case." Kumho Tire, 526 U.S. at 141. Rather, the district See

court's inquiry into the reliability of expert testimony under Rule 702 is a "flexible one." Daubert, 509 U.S. at 594.

discretion is considerable, it is not unfettered: It does not permit the district court "to perform the [gatekeeping] function inadequately." Id. at 158-59 (Scalia, J., concurring) (noting

that the majority opinion "makes clear that the discretion it endorses -- trial-court discretion in choosing the manner of testing expert reliability -- is not discretion to abandon the gatekeeping function"). As an initial matter, we reject Bobby's contention that the

district court abused its discretion by denying his request for a hearing. While the gatekeeping function requires the district

court to ascertain the reliability of Kuehner's methodology, it does not necessarily require that a separate hearing be held in order to do so. See id. at 152 (district courts possess

"latitude in deciding how to test an expert's reliability, and to decide whether or when special briefing or other proceedings are needed to investigate reliability"); see also United States v. Alatorre, 222 F.3d 1098, 1102 (9th Cir. 2000) ("Nowhere . . . does the Supreme Court mandate the form that the inquiry into . . . reliability must take. . . ."). This is particularly true if,

at the time the expert testimony is presented to the jury, a sufficient basis for allowing the testimony is on the record. See 4 Weinstein's Federal Evidence § 702.02[2] (Joseph M. McLaughlin ed., 2d ed. 2006). The remaining question, then, is whether there was a sufficient foundational basis in the record to support the trial court's decision to admit Kuehner as an expert? First, the district court noted with approval the decision in Santiago rejecting a challenge to the reliability of the government expert's firearms identification methodology as "pseudo-science." 199 F. Supp. 2d at 111. The Santiago court

stated that the government had submitted a letter describing, among other things, the method that the expert used to "match

particular guns to the bullets in question."

Id.

Moreover, the

preliminary ruling below in Santiago had accepted that much of the reliability inquiry would occur when the government laid the foundation preliminary to the district court's admitting the expert's testimony. See 199 F. Supp. 2d at 112 (noting that in

addition to expecting the government to ask about the expert's "training, experience, qualifications, and the methods he used to match the bullets with the guns in question," the court was "interested to learn how often [the expert's] identifications have been wrong in the past and the degree to which his methodology has been accepted in the community of forensics experts"). We think that Daubert was satisfied here. When the district

court denied a separate hearing it went through the exercise of considering the use of ballistic expert testimony in other cases. Then, before the expert's testimony was presented to the jury, the government provided an exhaustive foundation for Kuehner's expertise including: her service as a firearms examiner for approximately twelve years; her receipt of "hands-on training" from her section supervisor; attendance at seminars on firearms identification, where firearms examiners from the United States and the international community gather to present papers on current topics within the field; publication of her writings in a peer review journal; her obvious expertise with toolmark

identification; her experience examining approximately 2,800 different types of firearms; and her prior expert testimony on between 20 and 30 occasions. Under the circumstances, we are

satisfied that the district court effectively fulfilled its gatekeeping function under Daubert. The trial court's admission

of Kuehner's testimony constituted an implicit determination that there was a sufficient basis for doing so. The formality of a

separate hearing was not required and we find no abuse of discretion. We do not wish this opinion to be taken as saying that any proffered ballistic expert should be routinely admitted. Daubert

did make plain that Rule 702 embodies a more liberal standard of admissibility for expert opinions than did Frye v. United States, 293 F. 1013, 1014 (D.C. Cir. 1923). See Daubert, 509 U.S. at 588

(holding that the Frye test of general acceptance in the scientific community was superceded by the Federal Rules); see also Amorgianos, 303 F.3d at 265 (observing departure, under Federal Rule, from the Frye standard). But this shift to a more

permissive approach to expert testimony did not abrogate the district court's gatekeeping function. York, 414 F.3d 381, 396 (2d Cir. 2005). Nimely v. City of New Nor did it "grandfather"

or protect from Daubert scrutiny evidence that had previously been admitted under Frye. See United States v. Crisp, 324 F.3d

261, 272 (4th Cir. 2003) (Michael, J., dissenting); see also

United States v. Saelee, 162 F. Supp. 2d 1097, 1105 (D. Alaska 2001) ("[T]he fact that [expert] evidence has been generally accepted in the past by courts does not mean that it should be generally accepted now, after Daubert and Kumho [Tire]."). expert testimony long assumed reliable before Rule 702 must nonetheless be subject to the careful examination that Daubert and Kumho Tire require. See Daubert, 509 U.S. at 589 (explaining Thus,

that Rule 702 requires district courts to ensure that "any and all scientific testimony or evidence admitted is not only relevant, but reliable"); id. at 592 n.11 ("Although the Frye decision itself focused exclusively on `novel' scientific techniques, we do not read the requirements of Rule 702 to apply specially or exclusively to unconventional evidence. Of course,

well-established propositions are less likely to be challenged than those that are novel, and they are more handily defended."); see also Kumho Tire, 526 U.S. at 152 (explaining that whether a witness's area of expertise is technical, scientific, or more generally "experience-based," Rule 702 requires the district court to fulfill the gatekeeping function of ensuring that his or her testimony is reliable). Because the district court's inquiry

here did not stop when the separate hearing was denied, but went on with an extensive consideration of the expert's credentials and methods, the jury could, if it chose to do so, rely on her testimony which was relevant to the issues in the case. We find

23

that the gatekeeping function of Daubert was satisfied and that there was no abuse of discretion.

CONCLUSION For the foregoing reasons and those provided in the concurrently filed summary order, appellants' convictions and sentences are AFFIRMED.
