the Chief Special Agent no longer reported his office's activities directly to the Secretary of State, instead answering to the Assistant Secretary of State for Administration. Within the next two decades major passport fraud activities were detected and neutralized worldwide, often involving both Communists and Nazis. Office of Security During World War II, State Department agents were once again involved in interning and exchanging diplomatic officials of enemy powers. Around this time, the Chief Special Agent's office became known as SY (short for Office of Security), which in turn was under the Administration Bureau of the Management Undersecretary. After World War II, SY began expanding its presence overseas, with numerous Regional Security Officer (RSO) positions created in overseas posts. In 1961, Otto Otepka, then a deputy director of SY, brought to the attention of the U.S. Senate Internal Security Subcommittee deficiencies in the State Department clearance process. The allegations were traced all the way up to then Secretary of State Dean Rusk. Despite multiple awards, appeals from multiple U.S. Senators and not backing down, Secretary Rusk removed Otepka from his position and ultimately unceremoniously fired him. Starting sometime after World War II, SY began regularly protecting visiting heads of state, but it had done so sporadically since the 1930s. Before his departure in 1947, SY Director Bannerman began codifying procedures for overseas security. This process continued in the late 1940s, with a number of RSO positions being created. From that time and through the early 1970s, the number of agents remained relatively small, hovering around 300, with more than half of these serving overseas at any given time. The April 1983 U.S. Embassy bombing was a catharsis for the State Department, which would transform SY into the newly created Diplomatic Security Service, part of the Bureau of Diplomatic Security. Diplomatic Security Service Congress formed a commission headed by Admiral Bobby Ray Inman to look into the bombings of U.S. diplomatic facilities in Beirut. The resultant Inman Report recommended that security at the State Department needed to be elevated to a higher priority. In 1985, Congress created the Bureau of Diplomatic Security (DS), headed by the Assistant Secretary of State for Diplomatic Security, and the Diplomatic Security Service (DSS), headed by the Director of DSS, who is subordinate to the Assistant Secretary of State for DS. However, DSS is the federal law enforcement agency, and not the Bureau of Diplomatic Security
