As national border controls are removed, the external borders will assume greater significance to Member States. International crime is already on the increase so that techniques must be developed for suppression of inter-State serious crime. However, a police organization of a Federal nature raises questions of jurisdiction, accountability, and control as well as funding and administration. Three levels of police collaboration exist today as Member States subscribe to membership in the International Criminal Police Organization (Interpol), exchange information in the Trevi Group committees, and collaborate informally on a day-to-day basis with operation police of neighboring States as well as prepare joint policies. EEC-induced change will raise doubts about the quality of security and must be presented to the people with care.
