The Daily Mail has a story about an engineer who has demonstrated how to get metal objects past the TSA nude scanners. (H/T, Hot Air) Other folks have shown how to get PETN, the explosive that the underwear bomber used, past the machines.

Let’s see. These things can’t always find the explosives they are supposed to detect. They miss stuff that a cheap magnetometer will catch. There are potential health risks associated with their use. They cost billions.

I must be missing something.
