You can read meeting minutes from neighborhood and beat meetings to confirm this (there's probably lots of things you can read to confirm it, but the nerdiest way to do it is to get the raw data.)
A shorter way to say all of this: you're expressing a luxury belief.
Will surveillance cameras in low-income areas (if that’s where they’ll put them) mean that the police will be more responsive to crime in those areas? If the police are already not responsive in supposedly high-crime areas, what’s the underlying cause? Would the Black Panthers have felt the need to have armed patrols in their neighborhoods if the police could’ve put up a surveillance system?
The whole thing is silly; it isn't the job of municipal police to investigate price collusion and corruption in the first place. You might just as meaningfully say that the trash collection service should be prioritizing institutional racism.
