Shifts in criminality enabled by the globalised world are creating significant challenges for security in nation states. As crime and terrorism cross borders, so too must criminal justice strategies. The necessity of developing a transnational approach to policing, and the major political implications that go alongside, are at the front of the agenda in criminological debate. Considering law enforcement beyond the boundaries of the nation state, Global Policing examines the forms it takes in contemporary society and the trajectory of its future development. The text explores: - the emergence of a ‘new security agenda’ focused on serious organised crime and terrorism and how this is driving a transformation in all spheres of policing - the blurring of boundaries between police, military, secret intelligence and other ‘security sector’ agencies - the restructuring of local policing so that it is ‘globally aware’, the creation of national policing agencies with a transnational reach, and the posting of international crime liaison officers around the world - the creation of regional entities such as Europol and global organisations such as Interpol. Written by two of the leading experts in the field internationally, Global Policing considers the effectiveness, legitimacy and accountability of transnational policing in a lively and accessible style. With its exploration of cutting-edge theoretical debates brought to life with case studies and examples, the book is essential reading for students and academics in criminology, criminal justice, policing and international relations.
