In view of the TSA and the airline companies total inability to properly screen passengers as confirmed by recent events comes my prediction as to where this is all going: Soon airlines will strip all passengers naked and have them don paper coveralls. Then feed them tranquilizers so they dose off or stare contentedly into space in a condition of utter passivity. And no carry-on luggage either. Absolute safety. That's what it'll all come to eventually. It may take another decade or so but that 's what I see on the security horizon. And that's why I don't fly any more either.
Update: And when the above mentioned prophecy comes true then here is the other reason why I'm reluctant to fly. Especially when such items become commonplace amongst the black market arms dealers.
