One can never be too safe. In the latest act of capitulation towards those seeking to erode our liberty and privacy, Homeland Security introduces
The X-Ray Backscatter: "The X-Ray Backscatter inspection system creates photo-like images revealing explosives and plastic weapons, thereby reducing the need for physical body pat-downs."
Swell. How detailed is the image?
Privacy advocate and tech consultant Bill Scannel sez, "It shows nipples. It shows the clear outline of genitals."
Backscatters began testing in various airports last year; I am unaware of any reports of leaked photos.
Personally I have no problem with any of this: if you don't want anybody goggling your genitals (or googling your genitals), then there is a simple recourse: don't fly. Or lighten up: think of it as a nude beach. Also, consider joining a gym: it's healthy and we'd rather not see you like that.
