Today, the Washington Post republished a chart put out by the ACLU in a comprehensive report that highlights the disproportionate arrest rate experienced by White and Black Americans for marijuana possession. The report highlights how much more likely Black Americans are to be arrested than White Americans despite roughly similar rates of usage. The report suggests that the rise in popularity of the broken windows theory of crime reduction is a direct contributor. According to this theory, institutions that work to reduce or eliminate social indicators of crime (e.g., broken windows) will reduce the likelihood of real crime taking place. So this theory has led to the controversial stop and frisk policies of law enforcement, which appears to disproportionately target Black and Latino Americans. It seems fairly self evident that such a policy would play a large role in increasing the disparity of arrest for marijuana possession, and given the dubious relationship between stop and frisk policies and crime reduction, it begs the question of to what end such policies?
