At the end of the third day of protests in St. Louis following the acquittal of a former police officer accused of murdering a black man in 2011, officers were heard chanting “whose streets, our streets,” after making more arrests. Police arrested more than 80 protestors Sunday in downtown St. Louis who the mayor accused of “breaking windows and destroying property.” Some protestors say police were being unnecessarily aggressive in their tactics. A jury found former St. Louis police officer Jason Stockley not guilty of charges that he murdered Anthony Lamar Smith following a police chase. Prosecutors suggested Stockley planted a gun in Smith’s vehicle because the gun had Stockley’s DNA on it, but not Smith’s. The Washington Post and Slate have more on the St. Louis protests.
