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.
Also, can everyone afford to pursue lawsuits?
Yes, it is. Security cannot stop you for bypassing alarms and receipt checks. They have to have definitive proof that you stole something before they can lay a hand on you. Even in membership stores like Costco, the most they can do is cancel your membership. If they do touch you, there are plenty of lawyers who will take your case and only collect payment if you win.

This falls squarely into the genre of "yes, you are technically right, but you may have spent a week in jail and thousands to tens of thousands of dollars of time and money to prove it, for which you will not be fully compensated."
Not by security or police, so my point still stands.
