I love it when the defense of the goverment is REMEMBER 9/11. Yeah like we forgot.
However, blindly following your goverment without thinking is not any better then the claims that we forget 9/11. Throughout history some of the most horrid things have happend in societies where people just "followed the goverment" (Lets go back a little farther then 9/11, think WWII for example!) 9/11 did NOT make the goverment automatically right in all things and the TSA was a knee jerk reaction then, one that has never been dealt with properly.
I think airline travel is safer today then prior to 9/11 and I think the TSA checkpoints have little to nothing to do with that increased safety. IMHO safety was increased when the cockpits were secured and when your local law enforcement agencies, FBI and CIA realized the threat existed and took steps to deal with it.
Think about it, the "liquid bomb" was NOT found by the British airport screeners, but by law enforcement.
There are lots of problems with the TSA. One of them is that it's a dead end job which makes it hard to recruit good folks so they lower the standards and we get what we are paying for (Turnover on this job is huge and the goverment's retention plan $500 bonuses... You have got to be kidding? I have worked on outsoucring plans and it takes a LOT more then $500 to get folks to stay in dead end jobs!)
