"Professor Colin Rogers has produced a timely and comprehensive introduction to policing. Key areas of study from police history, accountability through to international policing and views on future developments combine to provide an excellent foundation for students of policing. Key points are highlighted and reflective questions raised to support learners in developing their understanding while directing them to additional resources. Highly recommended." Professor Stephen Tong, School Director of Research & Enterprise, School of Law, Criminal Justice and Policing, Canterbury Christ Church University, UK
