External Security Federal Air Marshal (FAM) Program The FAM program provides an anti-hijacking capability for U.S. civil aviation. The program provides a covert, armed security force capable of conducting anti-hijacking operations and of deploying rapidly. FAMs are specially trained Special Agents who travel on U.S. air carriers along routes and into areas where worldwide terrorist activities indicate the highest probability of hijacking. FAMs are authorized to carry firearms and, if they reasonably believe a person has or is committing a felony, they can make arrests without warrant for any offense against the U.S. The FAM program serves as a deterrent to hijacking and other forms of terrorist activity aboard inflight aircraft. It is authorized by the Federal Aviation Act of 1958, the Anti-Hijacking Act of 1947, and the International Security and Development Cooperation Act of 1985. Order 1650.6, Federal Air Marshal Program, governs the FAM program.
Yeah, you're absolutely right, Rivero. Everyone knows the Boston to L.A. route is just crawling with hijackers. /sarcarm.
Take your idiocy somewhere else. If you want to be an analyst so bad, join the C.I.A. Otherwise, you're just wasting our time.
