This book analyses the impact of Integrated Offender Management (IOM) on contemporary policing and separates the rhetoric from the reality. Drawing on a qualitative study within an English police force over two years, this book examines the experiences of prolific offenders, subject to IOM, and sheds light on the culture and practice of the police and staff from other criminal justice agencies, working within the scheme. While IOM has been judged to have had initial successes in reducing the criminal activities of prolific offenders, this book tests the validity of such claims and considers the apparent disjuncture between policy statements made about the workings of IOM and how IOM policing operations are realised on the ground. It makes a unique contribution to research on police culture and practice, and multi- agency working in the criminal justice system.
