Not that i actually care about the body scanner thing, but it really is just a waste of money. After 9/11 they "cracked" down on security but when the father of the terrorist that blew his shorts up specifically told our government that his kid was in cahoots with said terrorists, something still happened. In conclusion...if they government can't prevent a fiasco with a direct "heads up", why are we relying on security guards at the airport that have a nifty new toy?
It really just boils down to the whole statistics of how ya die, and i, for one, am going to gamble that it won't be in a plane crash which was a direct result of terrorism every time.
