I found the video on YouTube: Bobby Kennedy speaking to a rally of black people in Indianapolis in 1968, on the night Martin Luther King was shot. Bobby had been informed about King’s death by the mayor, who told him not to go to the black neighborhood because riots could break out. Bobby had replied, “Don’t tell me where I can and cannot go.”
In the darkness, standing on a flatbed truck, he spoke, unrehearsed, from his heart. “If you’re black, and you’re tempted to be filled with feelings of hatred and mistrust,” he told the crowd, “I would only say that I can also feel, in my own heart, (he pointed to his chest) the same kind of feeling. I had a member of my own family killed, but he was killed by a white man.
