AFTE Store - Firearm and Tool Mark Identification: The Scientific Reliability and Validity of the AFTE Theory of Identification Discussed Within the Framework of a Study of Ten Consecutively Manufactured Extractors

Since the advent of DNA technology, there has been increased scrutiny of the scientific reliability and validity of identification disciplines. Unfortunately, in the case of firearm and tool mark identification, there has not been one document that comprehensively discusses this issue with regard to the AFTE Theory of Identification, even though there have been numerous studies that have been performed to investigate the scientific validity and reliability of the theory and its underlying premises. This article will collate the relevant studies performed in this quest in an effort to bring together the many variables that have been examined to determine if the theory remains valid. An example of which would be varying methods of tool manufacture. In addition, within this article will be a study performed utilizing ten consecutively manufactured extractors. It has been determined through this further work and review that substantial support validating the AFTE Theory of Identification exists and that its scientific validity and reliability can be more than adequately defended.
