According to arrest numbers obtained from the Metropolitan Police Department and crunched by a statistician, between 2005 and 2011, D.C. cops filed 30,126 marijuana offense charges. A staggering number of those—27,560, or 91 percent—were filed against African-Americans. Only 2,097 were filed against whites. Folklore contends that pot-arrest asymmetries are about Blacks smoking outside and getting their getting their pot on street corners. Recent studies contradict that.
