Jon Corbett, the first person to sue the Transportation Security Administration over the body scanners installed in airports in 2010, has now discovered a shockingly simple way to defeat the expensive security measures.

Because the scanners show a person's body as a light figure on a dark background, and potential threats show up as a dark objects against that light figure, all Corbett had to do was hide a metal object on his side, where it would blend into the background.

To prove his point, he sewed a side pocket onto his shirt, put a metal case inside, and walked through security at two airports with no problem.

As Corbett points out, traditional airport metal detectors would have foiled his plan.

"The TSA has been provided this video in advance of it being made public to give them an opportunity to turn off the scanners and revert to the metal detectors," he writes. "I personally believe they now have no choice but to turn them off."
