NIST on firearm/toolmark comparison: expert judgment without numeric strength

what the source states
"The examiner will then assess how similar the two sets of marks are and determine if the bullets are likely to have been fired from the same gun or different guns." "After comparing the bullets, the examiner can offer an expert opinion as to whether they match but cannot express the strength of the evidence numerically."
what we infer
The discipline's own standards body describes comparison as expert judgment without numeric strength — context for why inconclusive results on damaged fragments should surprise no one and settle nothing.
limitations
  • This page does not itself use the identification/inconclusive/elimination vocabulary; that framing is the field's, not this page's.
