San Francisco used to not investigate or prosecute any of those crimes. Laptop stolen out of a car? Nothing to do. Now they catch video of it happening, follow the license plate, arrest the perpetrators. Catalytic converter stolen? We don’t investigate that.
Yes, police have shitty track records of abusing authority and technology. Does that mean we throw out all authority and technology? If you do we get the chaotic lawlessness San Francisco experienced for years.
So what’s the middle way? 1) Use the tech to fight crime. (Check! They’re doing it) 2) prevent abuses of that technology and authority (in progress, let’s see how it goes)
