Protesters lay on the ground during a "die-in" during a peaceful protest outside of St. Louis Metropolitan Police Headquarters in St. Louis on September 17, 2017. A non-guilty verdict of a former white St. Louis policeman in the 2011 shooting of a black man in St. Louis has resulted in two nights of peaceful marching eventually turning violent. Jason Stockley was acquitted of first degree murder charges in the fatal shooting of Anthony Lamar Smith on Dec. 11, 2011 following a high-speed chase. Police have made nearly 50 arrests while a score of businesses have suffered broken windows. Photo by Bill Greenblatt/UPI..
