I wonder if it’s inevitable that we will get denial of entry based facial recognition systems. It’s legally difficult to stop people from leaving the store whereas it’ll be much easier to prevent them from entering.

If someone shoplifts then they get banned from the chain, or a network of chains. This would be an alternative to police involvement. Restitution could be done proportionality and privately.

Of course there will be issues with it but I’m sure it could be cheaper to figure this out than the alternative loss prevention solutions.
