I greatly admire Bruce Schneier as well as Applied Cryptography, and I agree with his analysis in general. But the only thing that the porno-scanners have any chance of actually detecting that would not be detected by WTMTs are ceramic and FRP knives, which have never been used in any attack. How one might use a plastic knife to destroy a plane/train/ship is beyond me, but supposedly the porn-scanners can see the plastic cutlery. Also this new expansion into train stations, subways, ports and god knows what else is not a response to any attack. So they are making an attempt to be proactive. I suppose they should at least get "credit" for that.

Maybe they will continue the trend and stop the stomach or intestine bomber before he strikes by full video boroscope examinations of the large and small intestines and the stomach. God bless America. The land of the enslaved and cowardly.
