Last night, a grand jury in Ferguson, Missouri came to a sudden halt when they decided to not to indict Officer Darren Wilson in the August death of Michael Brown, the unarmed teenager who was shot and killed after an encounter with police. Protesters in Ferguson and across the country expressed outrage at the decision. It was soon after the saddening decision that Run the Jewels (Killer Mike and El-P) performed in St. Louis, just a few miles from Ferguson. Killer Mike, who is noted for his outspoken views toward law enforcement, delivered an emotional speech in which he blasted the country’s “war machine,” offered support to Brown’s family and the protesters, and even expressed fear for his own two sons.
