I live in Oakland and this is a difficult topic.
The type of crime common here is nearly impossible to address without technological assistance. People steal cars, drive into neighborhoods, then break into other cars and houses. They're gone sometimes before a 911 call can even be made, and far before the police arrive. The criminals know this and are just incredibly brazen about it. They'll finish the job with people watching and recording because they know there's no way for them to be caught. People get followed home and held up in their driveway. The criminals are often armed, and people have been shot and killed for even the mildest of resistance. One guy was killed a block from where I was standing for knocking on the window of a getaway car of some guys stealing another car in broad daylight.
Leaving aside broader and more fundamental fixes for crime, which are much longer term projects, the only near-term thing that actually reduces this kind of crime is arrest and conviction rates. In SF, drones have helped reduced car break-ins, because they've actually caught some crews. Oakland doesn't have drones that I know of, but Flock cameras have enabled enough tracking for police to sometimes actually find these people quickly, even several miles away, and make an arrest.
Those are just the plain facts of the situation. It's understandable that people want some kind of solution here. Without at least starting from that understanding, it'll be very difficult to convince people that a solution that is having a positive impact already is not worth the other costs and risks.
And to me, this is the core conflict at a really high level: the economic and societal fixes for crime are usually opposed by the same people who abuse these kind of surveillance systems for authoritarian purposes. To me it's no coincidence that their preferred solution to crime just happens to help them keep an eye on the whole population.
