Big difference in boarding an aircraft that can easily be used as a missile and being stopped anytime and anywhere and searched without any recourse.
Oh, hell no! No difference at all. Instead of searches, they should hand everyone a pistol.
The problem with travel is no different than the problem with no-gun-zone schools and cities.
The problem is that the right to self defense has been infringed.
PERIOD.
Searches never work.
Governmental edicts never work.
What will stop hijacks is when one never knows how many citizens on any given plane are packing, and willing to provide resistance. One or two hijackers shot dead, and all this bullcrap stops, and without cavity searches and ID checks.
Same exact thing Hitler, Mussolini and the rest of the genocidal tyrants in history always tell their people when they disarm them and start their stop and frisk programs.
That's right.
