Because the US government plans to use backscatter X-ray scanners on airline passengers - and with a method of X-ray technology that completely scans through clothing and basically leaves the person standing naked on the monitor. Great idea. Especially great is the reaction of the representative of this brain fart:
Chertoff had made it clear to the legislators, according to a report in the New York Times, that he did "not want endless debates" about data protection issues.
That could easily be from Otto Orwell, that saying ...
Well, just another reason not to want to travel to the USA. They really have a screw loose.
