This is why I've never stopped for receipt checks, because it's my receipt, and I've paid. The security theatre is just bad comedy.
Just because the machine says I've done a no no, doesn't mean I can't come back and win a lawsuit later. It doesn't abdicate cops from their jobs. I have a winning complexion, so I'll never enjoy a false positive, but if I do, I'll make sure it bankrupts whatever startup incubator garbage decided to shill a replacement for real law enforcement.
