Following an overview of contemporary structures of European policing, the dynamics of police cooperation are discussed. This is followed by profiles of the three most formalized arrangements that exist for police cooperation: the Schengen Convention, Interpol, and the so-called TREVI group. The next chapter addresses the more informal cross-Channel arrangements that exist in the south of England with France, Belgium, and Holland, as well as various other formats that have been devised for police to converse with each other across borders, including the meeting of police trade unionists and other associations. Also considered are some specific bilateral models of policing borders presented by the building of the Channel Tunnel, as well as the Anglo-Irish Agreement and its impact on policing for the RUC and the Garda Siochana. Other specific responses made within and between police forces to particular crimes such as drug trafficking, public order, and terrorism are discussed as well. Other chapters focus on the implications of current and emerging information technology for cooperation in policing Europe, the future of policing in Europe, and future research in this area. 3 figures, 5 tables, 4 suggestions for further reading, a 306-item bibliography, a subject index, and a list of organizations and sources of information
