This book is a practical and theoretical analysis of public protection and criminal justice. This area has seen immense change in recent years and the book examines the recent legislative, policy and organisational changes and their impact on the various agencies involved, including the police service and the probation service. Public protection has now assumed a position of dominance within the criminal justice agenda. New ways of working have necessitated changes to organisational culture, which in turn has begun to blur traditional criminal justice boundaries. Agencies must now work together by law and the public protection 'family' has extended to include a range of agencies, such as housing and leisure services.This book explores the problematic concept of 'dangerousness' and its application to criminal justice. All recent policy and legislative initiatives are examined within a critical context that questions the need for populist, punitive agendas, for example the creation of MAPPA (Multi-Agency Risk Assessment Panels) and changes in relation to the National Probation Service. Recent relevant legislative references are collated in a useful appendix at the back of the book.The book is a practical and useful reference, ideal reading for students and academics working critically in the area who wish to understand how public protection has reached its present status. It is also a useful reference for probation officers, police officers and policy makers.
