I mentioned "left-leaning, anti-police" because this particular city attempted to reduce its police force, due to a general distrust in (local?) police authority. It appears that USA police forces might be more violent because they are far more likely to encounter armed criminals (see source below). Thus it makes sense that some communities would prefer to reduce their police force, and might oppose technologies like Flock that increase the chances of police encounters:
Firearm Prevalence: U.S. officers operate in a society with high civilian gun ownership. A 2019 study published in PMC found that the strongest predictor of police being killed on the job—and consequently, their higher rate of using lethal force—is the level of household gun ownership in that state. In this context, U.S. "caution" often manifests as "command presence" to prevent a suspect from reaching for a weapon.
> left-leaning, anti-police
As if there is any correlation, or crimes don't occur in right-leaning locales.
> hypothetical/theoretical harm
Freedom is very real, and includes security from the state. The latter risks are hardly theoretical in history and very present today.
