I'm Michel Martin. And this is TELL ME MORE from NPR News. We start the program today with a memory. Fifty years ago today, a few minutes after midnight, civil rights activist Medgar Evers was gunned down in his driveway in Jackson, Mississippi by a white segregationist who wanted to stop Evers' work as a field organizer for the NAACP. He was just 37 years old, a war veteran, a husband, and father of three. Evers had put his life on the line to register voters. Here he is a month before his murder.
