This briefing paper provides an overview of the existing European Union approach to issues of security, counter-terrorism, and organised crime. In particular, it focuses on the role of the European Security Strategy (ESS) in the formation of policy and in the development of new institutions and institutional arrangements within the EU, and the influence of the Organised Crime Threat Assessment (OCTA). The paper argues that steps should be taken to streamline and rationalise the existing structures concerned with security, counter-terrorism and organised crime, and strongly recommends that a “Committee on Internal Security” be established to act as a single point of reference and clearinghouse for the work of the various EU agencies and institutions concerned with security, counter-terrorism and organised crime.
