Identification of two copper jacketed bullets
The AFTE Glossary defines identification as:
“Agreement of a combination of individual characteristics and all discernable class characteristics where the extent of agreement exceeds that which can occur in the comparison of toolmarks made by different tools and is consistent with the agreement demonstrated by toolmarks known to have been produced by the same tool.”
This statement reflects the concepts of sufficient agreement and best known nonmatch. All identifications are based on pattern matching. It is possible to go beyond this qualitative match to the quantifiable consecutive matching striae (CMS) approach to further support an identification.
