Like other post-9/11 things like DHS and ICE, we need to abolish TSA since it doesn't actually keep anyone safe, and actively harms people.
So just get rid of TSA and have no security? They find hundreds of guns in carry on baggage every year, but that should be no big deal right? They didn't force this person through the scanner, they could have asked for a supervisor and discussed the situation. Don't trust the people at the bottom of any organization if you have a concern.
No one suggested that. What do you think we did 30 years ago (look it up if you have to)? That, and locked cockpit doors: what value-add is TSA over procedures from 30 years ago?
