This is a thorough revision of the landmark book that standardized for the first time the language, terminology, and classifications used throughout the criminal justice system. It now includes considerations of new modes of communication both among criminals and those who pursue them. The Crime Classification Manual has been an indispensable guide for law enforcement, criminal lawyers, criminologists, forensic psychologists, and sociologists since its publication in 1992. As one reviewer on Amazon aptly stated, the Crime Classification Manual is to the criminal justice profession as the DSM-IV is to the psychology/psychiatry profession. ?This thoroughly revised guide uniquely provides the language, terms, and classifications the criminal justice system and allied fields use as they work to protect society from criminal behavior.
