The TSA is all security theater, anyway, and an overreaction to the last incident.Correlation does not equal causation. Besides there are other security measures that can put in place other than subjecting citizens to full body searches and even more invasive searches at the whim of a TSA worker.
Back around the time the TSA was created, more than one person pointed out that the Israelis had a much more effective solution in place, one that didn't inconvenience travelers and was actually effective at preventing problems: they had trained professionals who looked people in the eye and knew how to read the signs of impending trouble.
It's a funny thing: we had a bunch of people who also had that kind of training and had hard-won experience at implementing it, and quite a few of them were coming back home and looking for jobs in the civilian world. Funny how that solution to two problems never even got considered.
