Ok, I'm game. What's been implemented post-9/11 that's made us more secure?
I agree with Bruce Schneier on this: "Only two things have made flying safer [since 9/11]: the reinforcement of cockpit doors, and the fact that passengers know now to resist hijackers."
To make stupid people feel more secure by appearing to do something.
Sadly, most people confuse "activity" with "progress".
