Atlanta rapper Killer Mike was performing in St. Louis last night when it was announced that a Ferguson grand jury would not indict Darren Wilson for Michael Brown’s death. He spoke openly to the crowd about his own fears as a black father to two sons. "I knew it was coming and I knew when Eric Holder resigned, I knew it wasn’t going to be good." the rapper said tearfully. "I have a 20-year-old son and a 12-year-old son and I am so afraid for them."
