Interesting article on Biometric polygraph for airport security. This works by detecting emotional responses to a series of questions. If the person was nervous or worried the system could determine that. In tests it has flagged 85% "mock" terrorists and 8% of innocent passengers! 8% is a large amount....

So the question is..what if you are just nervous to fly, had a bad day or are just a emotional wreck to begin with? Biometrics is still an young technology that should be allowed to mature before sending this into every airport in America. The more undeveloped technology that is deployed for airport security, the longer it's going to take to get though security thats for sure.
