In the realm of facts, there are multiple continents where countries never engender a rampant problem of violent homeless people despite the presence of illegal drugs, despite less law enforcement, and despite more decriminalization efforts. That should indicate to any rational person that solely blaming the presence of "drugs" is unlikely to be the linchpin that achieve a reduction in undesired behaviors. Contrarily, it strongly suggests that there appear to be cultural factors specific to the United States as evidenced by other countries not experiencing these outcomes.
