Last night Piers Morgan invited Jackie Kennedy's former secret service agent Clint Hill onto the program for an honest and revealing exclusive interview. Author of the new book "Mrs. Kennedy and Me: An Intimate Memoir," Hill was riding behind the Kennedy's on the day JFK was shot and killed in Dallas, Texas. He tried to protect the Kennedy's after the first bullet was fired, but admits he got onto the car too late:
"I've always felt a sense of guilt," Hill said. "I was the only one who really had a chance and that has ate at me over the years that I should have gotten there fast enough perhaps and I couldn't."
Hill went back to Dallas in 1990 to survey Dealey Plaza and the sixth floor window from where the bullets rang out:
"I finally came to the conclusion that the advantages were all to the shooter that day," he said. "We had none and there really wasn't anything more that we could have done."
Meanwhile, actor and comedian Arsenio Hall also appeared live on "Piers Morgan Tonight" Thursday, offering his candid thoughts on the Trayvon Martin case.
"I think this kid did what my son's been taught to do," Hall said, referring to respecting authority, but always protecting yourself. "If a stranger walks up to my son he's either going to run or fight."
Watch the clips, and listen to the interviews, and as Hill and Hall open up about their lives, and discuss major moments in American history.
