I am a fan of these body-scanners to be honest.
No more need to unbuckle your belt, put off shoes etc. It is really a lot more civilized and less hassle.
So what if someone sees a naked LAYOUT of me! half the world is like me, the rest as my wife. Big deal.
And to those who claim that body-scanners intervene with the anti-childporn and personal freedom legislation: Get a life!
