The fact that this policy is intrusive, expensive and yet demonstrably irrational (at least on the part of the public) is pretty self-evident. The idea that we need some method, whether legal or social or both, to control irrational responses like this is a pretty a pretty natural conclusion after that.
Perhaps the idea that the government should not react due to irrational popular pressure is somehow libertarian, but really, it seems pretty non-ideological. Not wanting intrusions and restrictions on individuals just because a bunch of people are overly panicky is very reasonable.
