Coming now to prisons in the UK (that bastion of personal privacy), the B.O.S.S. Body Orifice Security Scanner. Basically a tool to detect various items secreted in various orifices (orifi?), this scanner is being put in place to combat the issue of cell phones, weapons, etc... being hidden in inmates body cavities. I dug around a bit to find the company selling the scanners and it appears that they are in New York. Hoo boy I can't wait until these start showing up in airports!

I guess that subject does look a little spammy now looking at it. I just couldn't resist 

I got to go through one of those full body scanners at our local courthouse a bit back. It was a bit of an odd experience. I'm just waiting for the images to show up on the internet.
