Volunteer Police, Choosing to Serve provides an in-depth comparison between volunteer policing in the United States and in the United Kingdom, and explores the shared past and similar-yet sometimes divergent-evolution of special constables, auxiliaries, and reserves. It discusses the history of volunteer policing, contemporary authority, functions, and training. The book also examines part-time, auxiliary, and special constable policing roles around the globe. The text contains original research comparing British and American volunteer police, and concludes with a discussion of the future of volunteer policing in the UK and US contexts.
