On top of that, actually punish people for willful violations of basic constitutional rights to keep whoever the airports hire from getting too big for their breeches (unlike the TSA...), and the problem -- if it actually exist -- should resolve itself.
Have you tried buying terrorism insurance recently? Guess who the primary provider of that insurance is.
Would your proposed model have prevented 9/11 somehow?
The San Francisco Airport Commission. Or am I not understanding the question?
Would it have stopped 9/11? Did the TSA? Did anything else we tried? Nope. Because we didn't know about it until it happened. What it would have done is made sure that the cost of the cleanup and re-build didn't turn into a decade+ long charlie-foxtrot situation, and would have incentivized the airports to not let it happen again, instead of just putting on a show.
The effort spent on security is wildly disproportionate to the risk-- based, it seems, on the supposition that terrorists care fabulously more about damaging faith in American air travel than actually killing Americans.
I'm not saying I know anything one way or another, but that seems crazy.
