Well there are alot of people up in arms about the privacy affects of them.
It's essentially a way to digitally remove clothing to check for weapons or other security infractions.
It's like strip searching, just easier and faster.
Heres a thought...
Obviously what ever waves they're using, it doesn't penetrate everything.
Otherwise the weapons, or the bodies for that matter, wouldn't show up on the screen.
Metal seems to be reflected, as does body fat.
So for the privacy fanatics, we should create a brand line of underwear that blocked the body scanners.
Maybe it could contain a metal mesh.
I'm not sure if that would work, but surely there is some form of material that would block the waves.
Even better, make Tshirts with lettering made out of the material.
It could say "Mind Your Own Business" or "I See You Too".
Just to mess with their heads.
And make stickers with the letters.
So people could write their own messages to our friendly TSA agents.
Just a thought.
