I like the point you’re making but let’s remember that actually, it’s not police training that causes officers to abuse and murder civilians. You could completely overhaul police training curriculum and it wouldn’t make much difference.
After all, being a cop doesn’t really require much training. Most of your learning takes place on the job, based on what you actually see other cops do and get away with. Learning the ropes means learning what kind of behavior is punished, what is ignored, and what is rewarded. Not what the rule book says, but how things actually go down day-to-day.
It’s the police as an institution - as a power structure - that causes police violence.
