While I agree there is some sort of 'mass psychology' at work here, I believe there are some additional (and more important factors). There is certainly a lot of irrationality in people who accept these things and who have no direct/executive power to change them. But is there irrationality in the people who decided to put these policies into place? I don't believe it. Quite the contrary, I believe the politicians who created and support these laws have other, unacknowledged interests, that are concealed behind the "terrorism prevention" mantra. There are so many other things that can be put into place, why are these guys deciding on these particular ones? A couple of things: money and control. I'm not a journalist, but it would be great if an investigative journalist analyzed the people and the interests behind these regulations. I suspect they would find connections with the companies who provide the screening equipment, and the policy decision makers. As to the 'control' aspect, this is more related to the psychological idea. The people in power crave control, so they will generally tend to favor policies in that direction. Which is why their power must be constantly monitored and kept in checked by us the people. Without that we can't have any long-lasting liberty.
