A good bit of the nastiness we see in American streets is at least partially as a result of our almost suicidal war on drugs.
Why do we even have a war on drugs at this point? It’s obviously failed. Nearly everyone acknowledges this. Yet it continues.
The answer is the state and the various parts of the anti-drug industry want drugs to remain illegal. (Pharma’s happy to see drugs illegal too for obvious reasons.) If we had no drug war police would have to concern themselves only with things like rape and murder which means fewer cops.
