The European Police Office (Europol) is an international police organization that was formed to promote cooperation among law enforcement agencies in the European Union. Framed within the context of the Treaty of the European Union, Europol’s mandate includes all serious forms of international crime, including international terrorism. This paper offers an analysis of the organization of Europol’s counter-terrorism operations in the context of the history and dynamics of international police cooperation. More specifically, on the basis of the bureaucratization theory of policing, Europol is reviewed to exemplify the dual forces of political control over the organization via the regulative bodies of the European Union, on the one hand, and the institutional autonomy and professional expertise of participating police agencies, on the other. The outcome of these dual forces can be expected to determine the course and outcome of counter-terrorist policing in the European Union in years to come.
