I've been in mainland China for the past year and I wish western politicians would get it through their skulls that most of the ccp model's upsides come from CCTVs in public areas and a police force that prioritizes stopping street crime.
EDIT: I guess I could add examples of what "other crimes" could be. Fraud, corruption, sexual abuse, all victimless crimes, hitmen?
I don't know much about the other categories you mentioned but I do know that president Xi is associated with a 'tough on corruption' stance that's widely seen as a major positive of his administration.
Where I am, the local speed cameras have annual documents about the street their on detailing pre-camera vehicle speeds and fatal (pedestrian) accidents and the decreases in both of them since the usage.
Afaik, the concern isn't that it "could slide" its that flock _is used_ by say Texas to monitor out of state abortions. That isn't solving street crime and certainly didn't benefit the local residents.
