We could roll back to the system before the TSA. It worked just as well. There was still security, it just wasn't such a clusterfuck. Test after test of the TSA shows they don't catch shit other than lots of people who forget to put medical devices, etc. in a separate compartment or take off their shoes or whatever new dumbass rule based on nothing they require. I've got TSA pre-check, Clear, and Global Entry so I don't typically have to deal with most of the bullshit other than the lines, but air travel still takes twice as long as it used to and for no reason whatsoever. If it made anyone safer, I'd support it, but I don't like having my time wasted on bad theater.
One of my favorite bullshit rules is the liquids in small containers in a separate plastic bag. I've never done it. Not once since they implemented the policy 20+ years ago. I've never been asked a single thing. My wife gets harrassed every time she has a liquid in a container a tenth of an oz over the limit. she must look like trouble and I don't, I guess, but the point is it's all for show and does nothing. People can, and have, taken whatever the hell they want onto planes since TSA came along, up to and including firearms.
Another favorite moment was when they wanted to physically search my seven-year-old daughter because they thought the bath bomb in her suitcase that her grandmother gave her for Christmas was an actual bomb (fucking geniuses). I told them the little pink suitcase was my bag, that it was my bathbomb, and they wouldn't be touching my daughter without trouble. They went along with it and searched me instead. They wanted to go to a private room, but I made them do it in front of everyone, so lots of folks got a nice view during the pants-dropping portion. It's all a joke. And I guess you were right earlier when you asked who touched me at the TSA, because I did get a nice "hey how are you" that day.
There are good people who work for the TSA, of course. It's a job and I don't blame anyone for working a job. The system is stupid, pointless, and serves no one, however. I can' think of a bigger waste of taxpayer money.
