I mean, FISA warrants had (have?) a 99+% approval rate despite many applications having serious deficiencies.
Utah’s e-warrant program has a 98% approval rate. Some warrants are approved in less than 30 seconds.
Warrants across the US are frequently approved on evidence as shaky as a single anonymous tip.
The problem (at least in my opinion) isn’t that facial recognition itself is inherently evil, it’s that:
a) There are no standards around the algorithms themselves in terms of reliability. Worse still, this can inadvertently lead to serious racial bias.
b) It can launder lousy evidence (this person looks vaguely like this grainy photo) into solid scientific evidence (the algorithm says it’s a 99.5% match!) providing justification for all sorts of warrants and raids on even flimsier ground.
c) It creates lousy incentives in favour of creating a surveillance state. The police already have out-of-control hardware budgets, and many don’t like the idea of that budget being used to monitor and record people at all times they’re in public.
If we had better police and court systems and better privacy law this might not have been necessary - but we live in the world we live in so I can see why this county would do this.
