The Federal Bureau of Investigation (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. In addition to its traditional law enforcement partnerships, the FBI works closely with private sector partners to share information on emerging threats through its leadership in organizations such as the Domestic Security Alliance Council and InfraGard.
