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.

Hi Guys, 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. --Jon

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.
