The court did not limit the testimony of the experts, but that may have been due to the experts limiting their own testimony: “Additionally, like the experts in Robinson, Mayland and Stevens testified that their conclusions were their subjective opinions based on their comparisons of the characteristics of the bullets and fragments. Neither testified that their opinions were scientifically certain, and Mayland specifically testified that he could not attach any type of probability to his identifications”
“Like the defendant in this case, the defendant in Robinson argued that the trial court should have excluded the toolmark and firearms identification evidence under Frye because it lacked a scientific basis. The court disagreed, finding that, while “federal and state courts have had occasion to revisit the admission of expert testimony based on toolmark and firearms identification methodology,” the courts have “uniformly” concluded that toolmark and firearms identification methodology is generally accepted and admissible at trial.”
