This book provides clear and comprehensive coverage of the policing system and police powers. This second edition has been revised and updated to take account of new legislation, case law and other developments in the area. 'The author is able to succinctly identify the main points in relation to each area and uses selected case law and statutory provisions to great effect.' - New Law Journal 'I greatly enjoyed this book and at the end was genuinely surprised as a criminal lawyer at just how much I did not know about this central component of the criminal justice system. Both students and practioners will find much interest within the 260 pages of text and I highly recommend its purchase.' - Andrew Keogh, Tuckers
