I agree with the premise that using a google-like AI to "detect someone who looks like a criminal" is a terrible idea; but I also think that if you're out in public you shouldn't expect privacy. Loads of people think if they go shopping at wallmart it is illegal to look at them and say "Oh hi Joe, how's the family?". I'm pretty sure the universal expectation of privacy is more harmful than taking a balanced approach and interacting with reality on reality's terms. The best outcome here is for cops to get bored, ask the city to offer a tax incentive to businesses to scan for known criminal faces & report 10 seconds CCTV before + after a hit is found, and now the police have a statistic they can use for policing. The big scandal is when "known criminal faces" start to contain "just alleged that X did Y", at which point it's merely political. If you are X, wait for the arrest and sue the city when you're proven innocent.
