Name of expert(s) who were the subject of the ruling
General admissibility of toolmark analysis
Summary of reasons for ruling
Defendant argues that firearms identification is not supported by a sufficiently scientific basis to be admissible (citing NAS2009 about subjectivity in the field). The court held that, despite the subjective nature, courts continue to allow firearm identificaiton testimony under 702 and Daubert (relying mostly on the Taylor analysis). The court held, however, that the subjective nature required the testimony to be limited.

Language imposed by court to limit testimony
"any ballistics expert may not testify that (1) he/she is “certain” or “100% sure” that two items match, (2) a match is to “the exclusion of all other firearms in the world,” or (3) there is a “practical impossibility” that any other gun could have fired the recovered materials. A firearms expert may only testify that, in his or her expert opinion, the bullet came from the suspect firearm to within a reasonable degree of certainty in the firearms examination field."

Notes
Court just held generally that this satisfies 702, but does not make a ruling on any specific part of 702.
“After a review of Defendants’ arguments, the NAS Report, and the relevant case law, the Court concludes that firearm and toolmark identification is sufficiently reliable for admission under Rule 702. Numerous courts across the country have conducted thorough analyses of the reliability of toolmark identification with firearms in light of the NAS Report. It appears that in every instance, the court determined that expert testimony on toolmark analysis was admissible. . . . Indeed, Woods has not cited a single case excluding this type of expert testimony.”
