The FBI is an intelligence-driven and threat-focused national security organization with both intelligence and law enforcement responsibilities. It is the principal investigative arm of the U.S. Department of Justice and a full member of the U.S. Intelligence Community. The FBI has the authority and responsibility to investigate specific crimes assigned to it and to provide other law enforcement agencies with cooperative services, such as fingerprint identification, laboratory examinations, and training. The FBI also gathers, shares, and analyzes intelligence, both to support its own investigations and those of its partners and to better understand and combat the security threats facing the United States.
