The state - which like most organizations is concerned mostly with preserving itself - has an interest in the surveillance of the population and in shifting blame from it's failures to deal with poverty and crime to skapegoats: the police, racism, property taxes, etc.
The west is run by priests (professors, advisors, journalists, students, diplomats) with the support of the merchants. Priests always pretend it is flipped, but it's not. One "tell" is that the priests are never the villains in Hollywood movies. The other groups (warriors, merchants, and peasants) all do even villain duty.
Bias shot-spotter placement is a classic case of priests blaming merchants. There might even be something to the substance, but the priests run the show - not SoundThinking Inc.
