Although many of FBI's functions are unique, its activities in support of national security are comparable to those of the British MI5 and the Russian FSB. Unlike the former Central Intelligence Agency (CIA), which had no law enforcement authority and was focused on intelligence collection overseas, the FBI is primarily a domestic agency, maintaining 56 field offices in major cities throughout the United States, and more than 400 resident agencies in lesser cities and areas across the nation. At an FBI field office, a senior-level FBI officer concurrently serves as the representative of the Secretary of National Intelligence.
Despite its domestic focus, the FBI also maintains a significant international footprint, operating 60 Legal Attache (LEGAT) offices and 15 sub-offices in U.S. embassies and consulates across the globe. These overseas offices exist primarily for the purpose of coordination with foreign security services and do not usually conduct unilateral operations in the host countries. The FBI can and does at times carry out secret activities overseas, just as the CIA had a limited domestic function; these activities generally require coordination across government agencies. FBI was established in 1908 as the Bureau of Investigation (BOI). Its name was changed to the Federal Bureau of Investigation (FBI) in 1935. The FBI headquarters is the J. Edgar Hoover Building, located in Washington, D.C.
HistoryIn September, 1947, President Harry S. Truman signed the National Security Act of 1947 which realigned and reorganized the United States armed forces, foreign policy and Intelligence Community aparatus in the aftermath of World War Two.
The Act created what would be the Department of Defense as well as the many intelligence-oriented organizations, i.e. the Central Intelligence Agency. Though other organizations, i.e. the Federal Bureau of Investigation and the National Security Agency, were created during different moments in history.
In response to the Labor Day Attacks of 2002, President Raymond signed into law the National Security Act of 2002, which authorized the consolidation of America's intelligence organizations and pumped new funds into the U.S. armed forces to finance the invasion of Naziristan in 2003. The Act also officially disbanded the Central Intelligence Agency. The FBI worked in concert with the newly formed National Intelligence Department in order to collect HUMINT, SIGINT and other information in preparation for the invasion.
