Although the public interest in criminal predators is extensive, the criminology of criminal predators is fragmented. Violent Offenders: Theory, Research, Policy and Practice, Second Edition aims to demystify the many different types of violent offenders we hear about in the media. This newly revised and updated Second Edition is a compilation of original scholarship from an international collection of applied and academic criminologists. Based not only on history and academic research but also on the experiences of author Peter Conis as a 25 year veteran of law enforcement, it provides students with a realistic view of why people commit violent crimes and how our criminal justice system, as a whole, responds to these offenders and these violent acts. It contains cutting-edge material on the broad category of criminal predators, including homicide offenders, sex offenders, financial predators, and conventional street criminals. Unlike other texts on the subject that narrowly focus on one type of criminal (e.g., serial killers), this updated Second Edition illustrates the systemic importance of predation in antisocial behavior.
