These confessions of an ex-TSA agent — Dear America, I Saw You Naked — are well worth reading. For example:

We knew the full-body scanners didn’t work before they were even installed. Not long after the Underwear Bomber incident, all TSA officers at O’Hare were informed that training for the Rapiscan Systems full-body scanners would soon begin. The machines cost about $150,000 a pop.

Our instructor was a balding middle-aged man who shrugged his shoulders after everything he said, as though in apology. At the conclusion of our crash course, one of the officers in our class asked him to tell us, off the record, what he really thought about the machines.

“They’re shit,” he said, shrugging. He said we wouldn’t be able to distinguish plastic explosives from body fat and that guns were practically invisible if they were turned sideways in a pocket.

We quickly found out the trainer was not kidding: Officers discovered that the machines were good at detecting just about everything besides cleverly hidden explosives and guns. The only thing more absurd than how poorly the full-body scanners performed was the incredible amount of time the machines wasted for everyone.

And:

But the only people who hated the body-scanners more than the public were TSA employees themselves. Many of my co-workers felt uncomfortable even standing next to the radiation-emitting machines we were forcing members of the public to stand inside. Several told me they submitted formal requests for dosimeters, to measure their exposure to radiation. The agency’s stance was that dosimeters were not necessary—the radiation doses from the machines were perfectly acceptable, they told us. We would just have to take their word for it. When concerned passengers—usually pregnant women—asked how much radiation the machines emitted and whether they were safe, we were instructed by our superiors to assure them everything was fine.

“Security Theater” seems like too benign of a term for these absurdities, I think. Now go read the whole article.
