What's supremely confusing is that the back scatter machines were meant to protect us against the growing threat of non-metallic weapons and yet many TSA demos show how effective they are at finding things like guns and knives. Such objects would be passively and reliably detected by a metal detector and now we find they can be easily taken through a back scatter machine. We've put incomplete tech and massive room for human error in between people and air planes. It's worse than security theater, it's a full digression in our our actual security. We're actually less safe than we were 15 years ago. If this man's video is to be trusted, it's now easier than ever to bring a box cutter onto an airplane. Boggles the mind.
