the fbi has jurisdiction over all federal and state laws
Federal Bureau of Investigation The Federal Bureau of Investigation (FBI), formerly the Bureau of Investigation (BOI), is the domestic intelligence and security service of the United States, and its principal federal law enforcement agency. Operating under the jurisdiction of the U.S. Department of Justice, the FBI is also a member of the U.S. Intelligence Community and reports to both the Attorney General and the Director of National Intelligence.[3] A leading U.S. counter-terrorism, counterintelligence, and criminal investigative organization, the FBI has jurisdiction over violations of more than 200 categories of federal crimes.[4][5]
Foreign Intelligence Surveillance Act The Foreign Intelligence Surveillance Act of 1978 ("FISA" Pub.L. 95–511, 92 Stat. 1783, 50 U.S.C. ch. 36) is a United States federal law which establishes procedures for the physical and electronic surveillance and collection of "foreign intelligence information" between "foreign powers" and "agents of foreign powers" suspected of espionage or terrorism.[1] The Act created the Foreign Intelligence Surveillance Court (FISC) to oversee requests for surveillance warrants by federal law enforcement and intelligence agencies. It has been repeatedly amended since the September 11 attacks.
