Schneier on TSA
I've lost a lost of pocketknives to TSA, so I was particularly biased to like the way Bruce Schneier framed TSA security.
Schneier on Security: Sneaking Items Aboard Aircraft
Security systems fail in one of two ways. They can fail to stop the bad guy, and they can mistakenly stop the good guy. The TSA likes to measure its success by looking at the forbidden items they have prevented from being carried onto aircraft, but that's wrong. Every time the TSA takes a pocketknife from an innocent person, that's a security failure. It's a false alarm. The system has prevented access where no prevention was required.
