Your questions and comments are valid, but I'd point out that the real question is, since 9/11/2001, why is it they the only real response the government has made is to increase their power? Why is it that only now are we starting to hear people talk a little about immigration? Why are airline pilots still unarmed? Why is it that the government thinks that the key to making airlines safe is to further disarm the passengers to the point that they'll throw you in jail for having a swiss army knife?
The man from the government who says he's here to help you is lying. He's here to help himself.
