A strong centralization of the police was typical of the entire territory of Slovenia in the period from 1945 to 1966; however, the number of police units continued to decline from year to year. Currently the Slovenian police are organized on three levels: State, regional, and local. Significant organizational changes occurred on all three levels after 1990. The process of reorganization is completed on the local and regional levels, but will not be completed on the State level until after the adoption of appropriate legislation. The Ministry of the Interior (MI) is responsible for Slovenia's internal affairs. Internal affairs involve issues of public safety, state security, administrative internal affairs, and other related issues. MI operational services are divided among the Police Directorate, the Criminal Investigation Directorate, the Operative and Communications Center, the Bureau for Protection and Security, and the Special Unit. The Police Directorate is responsible for public order and general police matters in the areas of road traffic and border issues. The Criminal Investigation Directorate investigates crimes; and the Operative and Communications Center is responsible for coordinating all MI services, including the coordination of regional Public Safety Administrations. The Bureau for Protection and Security ensures the protection of certain persons and buildings; and the Special Unit deals with specialized tasks, such as countering terrorism. This paper also profiles Slovenia's Public Safety Administrations and police stations, as well as the chronology of organizational changes. 3 figures
