Can't call it a war on drugs and militarize the police and then expect them to treat the streets like anything but a warzone.
I haven’t seen this work done, but I think that if many parameters were assessed (racial breakdown of country and police force, measures of racism, rates of drug use, drug policies, rates of police carrying weapons, and gun laws) that, by far, the greatest predictor of cops killing citizens would be gun laws. Is anyone aware of such studies?
