This book argues that policing should be studied in a truly comparative manner as a way of identifying more accurately the diverse features of police organisations and the trends which affect contemporary policing. Studying policing comparatively is also a way to develop more sophisticated theories on the relations between police, state, and society aiming at higher degree of generalization. In particular, broadening the empirical basis, often limited to Western countries, favours the formulation of more encompassing theories. The comparative analysis, then, is used to refine meso or macro theories on various aspects of policing. The book covers the challenges of comparative research in diverse areas of policing studies with innovative tools and approaches to allow for the development of that subfield of policing. It is a significant new contribution to policing studies, and will be a great resource for academics, researchers, and advanced students of Public Policy, Sociology, Political Science and Law. The chapters in this book were originally published in Policing and Society .
