The FBI stands for Federal Bureau of Investigation, which is a national security organization with both intelligence and law enforcement responsibilities. The FBI has a range of legal authorities that enable it to investigate federal crimes and threats to national security, as well as to gather intelligence and assist other law enforcement agencies. The FBIs investigative programs include counterterrorism, counterintelligence, cyber, public corruption, civil rights, transnational organized crime, and more. The FBI is the lead agency for enforcing civil rights law and aggressively investigates hate crime, color of law abuses by public officials, human trafficking and involuntary servitude, and freedom of access to clinic entrances violations. The FBI also investigates public corruption, which is its top criminal investigative priority, and weapons of mass destruction. The FBI is dedicated to eliminating transnational organized crime groups that pose the greatest threat to the national and economic security of the United States. The FBIs investigative philosophy emphasizes close relations and information sharing with other federal, state, local, and international law enforcement and intelligence agencies. The FBI also provides cooperative services, such as fingerprint identification, laboratory examinations, and training.
