Does the Federal Bureau of Investigation (FBI) use Unmanned Aerial Systems?

Does the Federal Bureau of Investigation (FBI) use Unmanned Aerial Systems/Unmanned Aerial Vehicles (UAS/UAV) or drones? I know that all of the United States Armed Forces service branches U.S. Army (USA), U.S. Marine Corps (USMC), U.S. Navy (USN), U.S. Air Force (USAF) and U.S. Coast Guard (USCG) use them for sneaky air attacks because the engine is very quiet and the drone is high up in the air with no pilot in it. U.S. intelligence agencies like the Central Intelligence Agency (CIA), possibly National Security Agency (NSA) and Defense Intelligence Agency (DIA) use it also. Even some U.S. federal law enforcement agencies use them like the U.S. Customs and Border Protection (CBP), possibly Immigration and Customs Enforcement (ICE), U.S. Coast Guard Investigative Service (USCGIS), maybe Transportation Security Administration (TSA) and Department of Homeland Security (DHS). Also maybe the National Aeronautics and Space Administration (NASA) might use drones. But how about other federal law enforcement agencies like FBI, DEA, ATF USSS, USMS, IRS-CI, EPACID, FDA-OCI, etc. How about INTERPOL? Detailed answers please.
