Man in Dallas' Dealey Plaza who says he witnessed the assassination of President Kennedy. He holds a photograph of President Kennedy's motorcade on Nov. 22, 1963 that shows him as a teenager in the background, standing on the street corner. He spends his weekends in the plaza telling his story to visitors to the historic site. Here, he stands next to the picket fence atop the infamous grassy knoll from where he says some of the shots came. (2011)
