Protests have taken place all over the country over the killing of George Floyd at the hands of Minneapolis police.Oklahoma City is no exception. What started out as a call for justice has turned into a demand for action. Black Lives Matter supporters in Oklahoma City will gather Sunday to protest recent killings of unarmed black men. Their message is one of solidarity, that what happened in Minnesota has stretched far beyond the state, and Oklahomans understand the pain people there feel.“To hear a black man call out for his mama -- it broke more than my heart. It broke more than my heart. It shattered my depths of my soul,” said protest organizer Sheri Dickerson. The reaction to Floyd’s killing has played over the news. But many in Oklahoma can empathize. Dickerson said the protest planned for Sunday is intended to be peaceful, but she understands why people in Minnesota have reacted differently. “All of the anger, all of the vitriol and all of the rage, it is appropriate,” she said. “And so I stand with my brothers and sisters in Minneapolis in exhibiting that however they need to.”“People are finally seeming to listen just a little bit more,” she said. Longtime black activist and journalist Roland Martin put the response to Floyd’s killing in a broader context.“It's one thing to have a reaction to the death of George Floyd, but you've got to now put the work in to begin to change the system to change the laws for these rogue cops,” he said. The protest will begin at 2:30 p.m. at NE 36th and Kelley. It is intended to honor not just Floyd, but also Ahmaud Arbery and the anniversary of the Greenwood Massacre.
