The Militia is us. This is about the Second Amendment, but it reminds me that the Shoe Bomber was subdued by the Fligh Attendent and the other passengers, and Flight 93 was prevented from carrying out its mission by passengers who figured out what what happening faster than the FBI did.

So forget whether the pilots need guns, why can't passengers carry them? If it were widely known that a quarter of all airline passengers were carrying firearms, it would stop hijacking permanently, and would probably stop the problems with unruly passengers.

This wouldn't prevent bombs planted in luggage, but it would prevent planes being used as terrorist weapons.
