'This is not your average book about policing. It draws from a wide range of disciplines - not just law and criminology, but political science, sociology and economics - to provide a rich tapestry of insights into what policing is, its benefits and dangers, and how it should change. If you want to understand modern debates about policing, including whether it should continue to exist at all, this book is a must read.' Christopher Slobogin, Milton Underwood Professor Law, Vanderbilt University Law School
