What We Investigate
Spies. Terrorists. Hackers. Pedophiles. Mobsters. Gang leaders and serial killers. We investigate them all, and many more besides.
The very heart of FBI operations lies in our investigations—which serve, as our mission states, “to protect and defend the United States against terrorist and foreign intelligence threats and to enforce the criminal laws of the United States.” We currently have jurisdiction over violations of more than 200 categories of federal law, and you can find the major ones below, grouped within our national security and criminal priorities. Also visit our Intelligence program site, which underpins and informs all our investigative programs.
