Haha sorry buddy, but I did, and not to toot my own horn but I'm fairly intelligent. I actually understand how this tech works, hopefully you will too to clear things up for you.

"A British company called ThruVision has developed a camera that can detect items such as guns, drugs and explosives under people's clothes without, for better or worse, being able to see their genitals. It holds a lot of promise for places like airport security checkpoints but stands to open up a huge can of privacy-hating worms elsewhere.
The camera is called the T5000, and it sees objects based on the Terahertz, or T-rays, that they emit. The camera works because all people and objects emit low-level electromagnetic radiation. Every material emits a different signature of Terahertz wave, which lies between infrared and microwaves on the electromagnetic spectrum. That means it can tell the difference between cocaine and flour but won't show the distinct outline of your danglers."
