The video is worth watching, even if you don’t speak German. The scanner caught a subject’s cell phone and Swiss Army knife — and the microphone he was wearing — but missed all the components to make a bomb that he hid on his body. Admittedly, he only faced the scanner from the front and not from the side. But he also didn’t hide anything in a body cavity other than his mouth — I didn’t think about that one — he didn’t use low density or thinly sliced PETN, and he didn’t hide anything in his carry-on luggage.
Full-body scanners: they’re not just a dumb idea, they don’t actually work.
