Actor Jesse Williams is best known for his role on the TV show “Grey’s Anatomy.” On Sunday night, he earned a standing ovation when he addressed the BET Awards. As he accepted the Humanitarian Award, Williams paid homage to police shooting victims, including Rekia Boyd, Sandra Bland, Eric Garner and Tamir Rice, who would have turned 14 on Saturday. “Police somehow manage to de-escalate, disarm and not kill white people every day,” Williams says. “We are going to have equal rights and justice in our own country, or we will restructure their function and ours.”
