Sandra Bland’s mother just spoke to a group of Congressional leaders. And none of them will forget her opening remarks: “I am here representing the mothers who have lost children as we go on about our daily lives. When the cameras and lights are gone, our babies are dead. So I’m going to ask you here today to wake up. Wake up … The tears are real, the pain is real, the problem is real. So, I don’t come here playing games with you all. I don’t come to sit and be a part of a caucus where we talk and do nothing. You, you, you, you don’t know my pain.”
