What does it mean to be 'under arrest'? Who can limit police powers, and why do miscarriages of justice occur? The fourth edition of Criminal Justice provides a comprehensive overview of the criminal justice system in England and Wales, as well as thought-provoking insights into how it might be altered and improved. Tracing the procedures surrounding the apprehension, investigation and trial of suspected offenders, this book is the ideal companion for law and criminology students alike. As the authors combine the relevant legislation with fresh research findings and policy initiatives, the resulting text is a fascinating blend of socio-legal analysis. Whilst retaining its authoritative treatment of the issues at the heart of criminal justice, the fourth edition has been fully updated with recent developments, including recent terrorism legislation and the Criminal Justice and Immigration Bill. Students are aided by the addition of chapter summaries and further reading lists, while a new Online Resource Centre directs them to related cases and current events, successfully highlighting the importance and ever-changing nature of the subject.
