Need I remind everyone that had AA and security personnel been diligent on 9-11, Mohammad Atta would nver had been allowed to board. He did everything but walk aboard with a "Hijacker" T-shirt on, yet despite all the red-flags, no one took it upon him/her self to question him. (Probaby because of the fear of PC Nazis jumping all over the case). Post 9-11, its still better to be safe than sorry, period.
