Over the summer, Killer Mike emerged as one of the most impassioned voices of reason in the hip-hop community following the fatal police shooting of 18-year-old Michael Brown in Ferguson, Missouri, in August. He spoke out on Fox News and CNN, in an op-ed he wrote for Billboard, and in various interviews. By coincidence, as Stereogum points out, he and Run the Jewels partner El-P were in St. Louis on Monday night for a stop on their current tour. And the duo took the stage shortly after the grand jury’s decision’s not to indict Ferguson police officer Darren Wilson was announced.
