| Summary |
"Current Methods in Forensic Gunshot Residue Analysis examines major areas of gunshot residue analysis such as current and future methods of analysis, collection techniques, interpretation of evidence as well as expert testimony and report writing." "This text is a necessity for any forensic scientist conducting this type of analysis and all other law enforcement personnel, academics, and lawyers involved in the investigation and prosecution of violent crimes involving firearms."--BOOK JACKET |
