Last night, the decision of a St. Louis County grand jury to not indict Ferguson Police Officer Darren Wilson was announced, leading to protests in many cities across the U.S. In Ferguson, Missouri, where Officer Wilson shot and killed Michael Brown last August, demonstrations quickly turned violent, despite calls for peaceful protest from the Brown family and members of the community. Cars were smashed, stores looted, and at least a dozen buildings were set on fire, as a heavy police presence tried to establish order. Due to safety concerns including sporadic gunfire, firefighters were unable to respond quickly, and a number of businesses burned to the ground. As the night became early morning, arrests were made, streets were cleared and most fires were extinguished.
