Third party policing represents a major shift in contemporary crime control practices. As the lines blur between criminal and civil law, responsibility for crime control no longer rests with state agencies but is shared between a wide range of organisations, institutions or individuals. The first comprehensive book of its kind, Third Party Policing examines this growing phenomenon, arguing that it is the legal basis of third party policing that defines it as a unique strategy. Opening up the debate surrounding this controversial topic, the authors examine civil and regulatory controls necessary to this strategy and explore the historical, legal, political and organizational environment that shape its adoption. This innovative book combines original research with a theoretical framework that reaches far beyond criminology into politics and economics. It offers an important addition to the world-wide debate about the nature and future of policing and will prove invaluable to scholars and policy makers.
