Plus... the TSA exclusively searches people who are already in America. People support it on the generally prevalent notion that it prevents a flow of terrorists, which is just obviously not true. The TSA does nothing to prevent terrorists from flying planes into America. If anything it would prevent terrorists from hijacking planes to divert to other countries. I genuinely think the only reason people support it is the mental association "of planes bring people here" and "terrorists are other places".

The TSA notionally prevents the use of domestic and outbound international airplanes as weapons. In order to hijack a plane you would need to subdue hundreds of people (because why take over a small plane), find and subdue the air marshall, break into the cockpit, and know how to fly a massive jetliner. It is an insane concept. You could just buy a schoolbus(legal), steal a truck, or even just rent a big uhaul, fill it with explosives(undetectable and not even checked for), and drive it onto a big bridge or next to a stadium(also legal). You wouldn't even have to kill yourself to do it, you could kill many more people, and it would be almost impossible to stop.

If you just wanted to kill people you wouldn't even do that. You'd just set up IEDs like people do in Iraq and Syria. That would be way more terrifying than plane hijacking- the bombs could be everywhere. There would be nearly nothing we could do about it.

The fact that none of that happens says that terrorism is just not a threat in the way we think of it. The TSA is the most useless government organization in the US.
