That’s not the point of terrorism. If you blow up a TSA building, citizens get scared because it looks like „if the state can’t even protect itself, how are they going to protect me?“.

there are semi-competent arms of the US security apparatus that are not principally theatrical, that I would find shocking to be hit. The NSA comes to mind.

If anyone ever hit the TSA I'd just laugh at their piss-poor targeting. Thanks for clearing out our dusty community theater, now maybe we can build an ice cream shop there or something else actually useful.
