The FBI's Secrets Interesting Documentary

The Federal Bureau of Investigation (FBI) is the domestic intelligence and security service of the United States, which simultaneously serves as the nation's prime Federal law enforcement organization. Operating under the jurisdiction of the U.S. Department of Justice, FBI is concurrently a member of the U.S. Intelligence Community and reports to both the Attorney General and the Director of National Intelligence. A lead U.S. counterterrorism, counterintelligence, and criminal investigative organization, FBI has jurisdiction over violations of more than 200 categories of federal crime. Although many of FBI's functions are unique, its activities in support of national security are comparable to that of the British MI5 and the Russian FSB. Unlike the Central Intelligence Agency (CIA), which has no law enforcement authority and is focused on intelligence collection overseas, 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 Director of National Intelligence (DNI). Despite its domestic focus, 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. It is of note that FBI can and does at times carry out secret activities overseas, just as the CIA has 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.
