No thanks. Now anyone with a minor budget can run every single police video through image recognition and get a whole lot of private info on folks you likely don't want getting out.
Happen to be at a party that was broken up due to noise complaints? Drugs were found there? Why were you caught on camera leaving the house when officers arrived? Sounds like you are a liability!
If this actually happened I would give it 6mo before you get a credit agency or something of their ilk providing this data to such agencies for background checks/employment checks/etc. It will take the social media data mining and now include all law enforcement interactions ever.
I, for one, do not want to live in the world where I get to explain every traffic stop to a future employer or my insurance company. I'm sure both would absolutely love that information to use against me.
I think the writing is on the wall on this one though. In my lifetime I fully expect what I describe above to be happening behind the scenes in "public private partnerships". In some cases it already is.
Just yet another way to create permanent second-class citizens like we have with felons, and are trying as hard as we can to extend that into other areas of society.
