This text will explore the field of police and policing, mainly from Britain and Continental Europe, although there will be some comparative coverage with the US, Canada and Australasia. It is a theoretically informed text, but will also include a wide range of important policy issues relating to police and policing, and draw upon a great deal of empirical research in the field. The authors have extensive experience in this field. The text brings up to date the discussions surrounding police and policing, discussing areas such as measuring police effectiveness, race and gender, the impact of changing technologies, the changing face of policing, and the internationalisation of police and policing.
