This is a well-worn rant from everyone who has the joy of air travel: the fucking security theater that is the TSA.
The biggest sham that points it out to be a sham is the pre-screened line. All you do is pay your cash to some random company which, in-turn, is paying a lot to the government. That company then “screens” you. By “screen” I’m quite sure it’s “does your payment clear.”
If someone wanted to do something bad something bad would be done.
Life is full of risks.
You have to deal.
You shouldn’t just randomly give up freedoms like that. To feel better about traveling.
