These days, Air Marshals are required to carry Tarot cards or some other divining tool in order to figure out if a passenger claiming to have a bomb actually has one. Failing that, they must gently ask the passenger to fill out a 3 page questionnaire and consult with a sensitivity specialist to make sure no one's feelings are hurt.
Or, just maybe, if someone has mental problems, the family can properly care for him and make sure he doesn't run down the aisles of airplanes screaming about bombs.
And by the way, the first paragraph was sarcasm, in case someone thinks I was serious.
