I got into this in November 2010 when I was outraged that the TSA introduced the scanners as primary screening in conjunction with the pat-down. I filed suit that month in U.S. District Court, and have been fighting against TSA abuse since then. I work for no government agency.
I've actually had several comments left on my blog from IP ranges belonging to the body scanner manufacturers. It would not surprise me if a vast majority of pro-TSA posts on the Internet are written by DHS or manufacturer employees.
If you watch the video closely in 720p/full-screen, you can clearly see the metal object in my pocket. If you'd like, I can upload a high-res version of the relevant security camera to make it easier to see.
Video creator here. I actually did it with both the new L-3 ATD (the kind where they allegedly do not look at the nude pictures the machines generate) and the Rapiscan backscatter x-ray where they still visually examine your nude body. The vulnerability I identified applies to both technologies.
Thanks for taking this story up! Whether or not this video is your cup of tea, I think almost all of us can agree that ending TSA abuse and waste is hugely important.
I'd be happy to answer any questions you have posted in reply to this.
Video creator here. Jennifer CC'd her letter to Congress to the TSA, which is why the TSA was able to turn around on it within a week. Regarding the SOP, yes, she could have asked for it, but that's not the point: there is a manual to do screenings, and the people who do them aren't required to RTFM. That's a huge problem.
