On April 4, 1968, I was 11 and growing up in Memphis when the news came that Martin Luther King had been murdered. My parents couldn’t hide how bad it was – they were angry. They were afraid. And most memorably to my childhood self, they were crying. I couldn’t articulate it at the time, but I know now that I was afraid that killing the dreamer could kill the dream.
