Sample text

The object is to determine whether the individual characteristics are so similar that one and the same tool (for example, a particular gun barrel) must have produced both the test and the evidence toolmark. CONFUSING FEATURES OF TOOLMARKS Central features of toolmarks make it difficult to achieve what is firearms identification’s goal of individualization. The goal is to identify one and only one gun as the source of the toolmark(s) on an ammunition component found at a crime scene. First, a particular firearm may be wrongly identified as the source if a firearms examiner confuses subclass with individual characteristics of toolmarks.

What is the likelihood that a toolmark made by a randomly selected gun of the same type would do as good a job at matching the evidence toolmark as the test toolmark made by the particular gun? The statistical nature of the question is obscured by firearms examiners’ practice of reaching only four conclusions: (1) identifying or (2) eliminating a particular firearm as the source of the mark(s) found on an ammunition component, (3) concluding that the comparison of test and evidence toolmarks is inconclusive, or (4) concluding that the evidence toolmark is unsuitable for comparison.
