Digital forensics practice is implemented in either digital forensics labs or environments similar to traditional forensic labs that separate evidence processing from investigative areas of police agencies. Little is known about the variation in digital forensics practice in the United States as adopted by large local police agencies. The book presents an overview of the adoption of digital forensics practice by municipal police agencies in America. Numerous examples of police practices were identified and exemplified in order to illuminate from whence this study inherits its approach. The study elucidated digital evidence, cybercrimes and the incidental value of digital forensics practice, characteristics of digital forensics practice in police agencies, and investigations of cybercrimes and digital evidence.
