I'd add allowing qualified passengers to carry handguns.
I won't defend the TSA or Big Sister at all, but just pointing out that they weren't using these.
I didn't watch the subtitled version, so I'm not clear on exactly was going on. But the images - which didn't look at all like the screen shots that I've seen online - were a tip-off that this didn't represent current equipment.
If anything, the video supports the use of the TSA's active screening technologies (backscatter and millimeter wave devices). The scanner being used is neither of these, it is an entirely passive device - see: http://www.thruvision.com/Products/TS4_Sub_Pages/TS4_Product... for a brief explanation of their technology. While ThruVision's scanner is arguably safer, it is clearly deficient in detecting threats.
And it isn't being used by the TSA. In fact, ThruVision's website does not cite a single instance of their scanner being used anywhere in the world for passenger screening.
In other words, the video has NOTHING to do with current screening technology.
