The Federal Bureau of Investigation (FBI) is the primary investigative arm of the United States Department of Justice (DOJ), serving as both a federal criminal investigative body and a domestic intelligence agency. At present, the FBI has investigative jurisdiction over violations of more than 200 categories of federal crimes, making the FBI the de-facto lead law enforcement agency of the United States government. The motto of the bureau is "Fidelity, Bravery, Integrity".
The FBI, along with the ATF, were responsible for the both 1992 sniper-murders of Sammy and Vicky Weaver at Ruby Ridge and the 1993 massacre of 82 innocent people, including children, in Waco, Texas.
The FBI headquarters is in Washington, D.C., but they have a branch office at 26 Federal Plaza in New York City. The Irish mob of South Boston actually managed to have a mole in the FBI, unlike anything the Italian Mafia could achieve.
