TSA's Body Scanners -- Easily Defeated

At least that’s what blogger Jonathan Corbett claims.

Watch the video for yourself. Is it really that easy to defeat TSA’s million dollar machines?

***disclaimer - this dude is pretty far out there. But if you ignore the lecture his method of defeating the scanners seems to work. I’m curious to see what happens when others give this a try with something legal like a sewing kit.

It looks like the “solution” is to put the item on the side of your body. This wouldn’t defeat a patdown. Also, couldn’t the TSA start taking 4 pictures (front back left and right) instead of just front and back? Or does the technology only work front to back?
