Forty years ago this week, the nation was rocked by news of the shooting deaths of four students at Kent State University during a campus protest. In the years since that day, May 4, 1970 has come to be known as the day the war came home. Jerry Lewis was a young professor when he saw the smoke come out of the National Guardsmen's guns. Many people in the crowd thought the bullets were blanks - Jerry, a former Army man, knew immediately that they were the real thing. In the chaotic aftermath of the shootings, Jerry had to push aside his own feelings of fear to try to help the students he was there to protect. He talks with Dick Gordon about what the events of May 4th mean to him forty years later.
