Query: When does the FBI work with the US Coast Guard and US Customs and Board Protection?
Context: The FBI often works in conjunction with other Federal agencies, including the U.S. Coast Guard (USCG) and U.S. Customs and Border Protection (CBP) in seaport and airport security, and the National Transportation Safety Board in investigating airplane crashes and other critical incidents. Immigration and Customs Enforcement Homeland Security Investigations (ICE-HSI) has nearly the same amount of investigative man power as the FBI, and investigates the largest range of crimes.
