I remember at the time, much was made of the clip-on tie on the ground and speculation was that RFK had pulled the tie off of the shooter. Later a photo tkaen shortly after the shooting showed Cesar without his tie.
According to the San Francisco Chronicle, the chief questions are the facts that “the coroner reported that the fatal shot was fired less than one inch from Kennedy’s head behind his right ear. Four shots came from the rear but Sirhan fired a .22 from a few feet in front of Kennedy. The revolver held eight rounds, but a radio reporter’s tape recording of the shooting has sounds of what one audio expert describes as 13 shots and double shots.”
