''By bringing the frontier into the foreground, Lippert and Walby challenge us to question established theories and empirical research into both the historical and contemporary roles and objectives of modern policing.'' Ian Warren, Deakin University ''Lippert and Walby have been instrumental in pushing forward the study of plural policing into new and uncharted territory. This thought-provoking and imaginative book continues the journey.'' Adam White, University of Sheffield ''This fascinating book breaks down both national and academic borders in order to present a much richer understanding of the increasing coalescence of policing and security provision at the vital but under-researched frontiers of service delivery.'' Sarah Charman, University of Portsmouth "This excellent book adds significantly to the rich body of international scholarship exploring diverse and novel policing and security developments. Utilising innovative methodological approaches, it develops new empirical and conceptual insights into the contemporary nature, logics, practices and working relations of public and private forms of policing.'' Stuart Lister, University of Leeds ''Lippert and Walby forcefully show how studying policing and security frontiers is essential to understanding how a number of diverse institutions, actors, logics and strategies are transforming policing today." David Moffette, University of Ottawa ''This book is an essential source of information for both scholars and practitioners interested in policing beyond the police: corporate security guards, community safety officers, ambassador patrols and others working on the frontiers of security.''
