The book uses a structure that mirrors many university courses on criminology - starting with definitions of crime, then examining why people commit crime, and how crime can be prevented and detected. Later chapters hone in on the criminal justice system itself, examining the role of the police, the courts and prisons. This book is unique for its comparative approach to criminology, enabling students to understand criminology in the context of the UK, the US and further afield.
