Rafer Johnson -- a decorated Olympian and American hero -- has died, TMZ Sports has confirmed. He was 86.
Johnson lived such an amazing life as an athlete, actor, philanthropist and hero -- it's hard to pick where to start when telling his story ...
How about this ... he was one of the brave men who tackled and subdued gunman Sirhan Sirhan seconds after Robert Kennedy was assassinated back in 1968.
In fact, Johnson ripped the gun away from Sirhan and hid it in his own pocket to prevent any more violence.
