This textbook provides a comprehensive examination of all the required areas of criminal and policing law in the UK, with explicit links to the National Occupational Standards. Chapters open with clear objectives and include regular revision notes, knowledge check questions and answers, and practical activities. This second edition has been fully revised to expand the content, take account of recent changes, and reflect the latest UK legislation. In particular, there is a new chapter on Police Community Support Officers. The sections on police powers, traffic policing, and evidence have been updated, and the issue of diversity has been woven into an increased number of scenarios.
