Transnationalism is a relatively new concept in the social and political sciences, emerging from increasing interest in the changing nature of the state-system and society. This interest ranges from the local to the regional to the global, with globalization currently a much-debated topic across the social science. This volume is written from a criminological perspective and examines the effects of an emerging global culture on the nature of police and policing. Its main purpose is to identify the parameters of this new topic, addressing a range of issues including: the global market in private security; the perceived need to police cyberspace; the use of civilian police in conflict situations; and transnational police entities such as Interpol and Europol. Drawing on original research from a range of international contributors including the UK, North America, South Africa, France and Belgium, it should be of interest to a world-wide readership.
