RFK Jr. believes second gunman involved in father's assassination
Robert F. Kennedy Jr. is questioning whether his father's 1968 assassination involved a second gunman. Sirhan Sirhan is serving a life sentence for the murder, but Kennedy Jr. told the Washington Post that once he saw the autopsy report, "I didn't feel it was something I could dismiss. I was disturbed that the wrong person might have been convicted of killing my father." CBS News correspondent Tony Dokoupil reports.
