Are you sure there's no "permananent storage"? Who has verified that?

Second thing: there have been numerous instances of TSA workers leering at the scanner screens as people (esp attractive women) walk through. There have definitely been instances of attractive women being "randomly" selected.

If you think petty bureaucrats should have the power to leer at a curve-revealing outline of you and your loved ones in private at their whim, I'm sorry but you're just too complaisant for a strong democracy.

On a related note, how do you feel about airport toilet/shower "security" cameras with a promise that the tapes are deleted every hour? You know, just to prevent people from smoking drugs there. Airport is a public place, so it should be ok to watch you at all times, right?
