A lot of police policy wonks explicitly argue for replacing the human judgement of cops with impersonal, tech-mediated surveillance, on the grounds that this reduces the possibility of human bias against groups of people (typically black people); or just reduces the possibility of physical contact between a cop and certain people (again, typically black people), which therefore reduces the chances of the police stop escalating into a shooting. This is an argument for e.g. automatic red light cameras in lieu of having police stake out and pull over cars who run red lights.
