At the plenum of the Central Committee in July 1966, the political leadership accused the SDB of hindering reforms towards self-administration. As a result, the SDB was decentralized, its personnel reduced (especially on the federal level) and control commissions established. New regulations were issued, strengthening the independent initiative of the state security services of the six Yugoslav republics and the autonomous provinces. The SDB was deprived of executive functions and entrusted with identifying and preventing hostile activities. The Act on Internal Affairs and the Decree on Organization of State Internal Affairs Secretariat regulated the intelligence security authority as the prerogative of the State Security Directorate within the Ministry of the Interior. The following reorganization addressed issues relating to the competence of the federation (state security, cross-border traffic, foreign citizens, passports, introduction and dissemination of foreign press, and federal citizenship). Structure Intelligence and security activity was organized in the following manner: After OZNA ( / Odeljenje zaštite naroda) (En:Department for the People's Protection) was abolished, intelligence activity was divided among various federal ministries: the Federal Ministry of the Interior by the State Security Administration, and the Federal Ministry of Foreign Affairs by the Service for Research and Documentation (SID) which collected foreign political information; military-defense intelligence was handled by the GS 2nd Department - KOS (Kontraobaveštajna služba / / Counterintelligence Service) of Yugoslav People's Army. SDB in the republics was not autonomous, but was tied to the federal service which co-ordinated the work and issued instructions. State security was regulated by secret legislation (secret Official Gazette), which prescribed the use of special operations. The SDB performed house searches, covert interceptions inside the premises, telecommunications interception, covert surveillance of people, and covert interception of letters and other consignments. Of primary interest to the SDB was domestic security; identifying and obstructing activities of the "domestic enemy" (i.e. the "bourgeois rightwing", clericalists, members of the Cominform, nationalists, and separatists). Intelligence work abroad was deemed less important and was under federal control. The SDB was a "political police", answerable to the party organization from which it received its guidelines and to which it reported. The SDB was so deeply rooted in the political system that one of its tasks was the preparation of "Political Security Assessments"; that is, assessments on literally all spheres of life. During its activity, the SDB enjoyed a wide range of power, including classical police powers (identifications, interrogations, and arrests). The
