So...by that logic, the theater aspect of TSA is completely invisible to the majority of voters, and they get no satisfaction of increasing safety. They might see a news item on TV once in a while, that's about it. Doesn't seem to me like we can blame voters for what the TSA does, at least not today's voters.

Voters after 9/11, on the other hand, were definitely security-minded, and the political response to that is how the TSA became the juggernaut that it is today.
