In the 1990s private security patrols in public places were occurring in many areas of the UK and moving closer to that traditional domain of the public police - streets and neighbourhoods. Such a phenomenon was ripe for sociological enquiry and, accordingly, this book, originally published in 1995, provides a focused interpretation of six key concepts, each central to the equity debate on private policing.
