Backscatter X-Ray Technology: "The TSA has recently announced a proposal to use these machines to screen airport passengers.

I'm not impressed with this security trade-off. Yes, backscatter X-ray machines might be able to detect things that conventional screening might miss. But I already think we're spending too much effort screening airplane passengers at the expense of screening luggage and airport employees...to say nothing of the money we should be spending on non-airport security.

On the other side, these machines are expensive and the technology is incredibly intrusive. I don't think that people should be subjected to strip searches before they board airplanes. And I believe that most people would be appalled by the prospect of security screeners seeing them naked."
