The number of US air marshals (specially trained, plainclothes armed federal agents deployed on airliners) has shrunk from about 2,000 during the Cold War to 32 by 9/11. None are deployed on domestic flights. The number is later increased to about 2,000, but it would take about 120,000 marshals at a cost of $10 billion a year to protect all daily flights to, from, or within the US.
