I'm a pretty firm believer that what we go through at airports is security theater, and I know there are plenty of examples of all the things that have managed to slip past TSA (like this one), but seriously people - what the fuck are we doing? Although obviously the government isn't broadcasting the real results, some reports allege that between 70% and 100% of random tests of airport screeners are successful (meaning the covert government agent gets through security with a 'test gun, bomb part or knife.').
