AFTE Store - A Comprehensive Validity Study for the Forensic Examination of Cartridge Cases

Very little comprehensive research has been conducted to date on the scientific validity of traditional forensic cartridge case comparisons. This study is an initial attempt to remedy this scarcity, and was conducted under the assumption that the firearms -toolmarks examiner is an integral part of a scientific process leading to a reported conclusion. Thus, conclusions were drawn by a group of control examiners, in this case those in the Firearms – Toolmarks Unit of the FBI Laboratory. The results herein confirm the scientific validity of traditional comparisons.
