The events of the moment (in gory detail, be warned) Kennedy was killed, as told by the Secret Serviceman who leapt onto the back of the limo after the shots were fired.
In the clip — known as the “Zapruder film,” for Dallas dressmaker Abraham Zapruder, who shot the footage — a Secret Service agent is seen running toward Kennedy’s limo. As the car speeds up, the man struggles to hop on. He grabs a rung, nearly slips, and pulls himself aboard. Pushing Jacqueline Kennedy back into the car, he drapes his body over hers and the fatally-wounded president as the car speeds to Parkland Memorial Hospital.
That man, Clint Hill, told me all about it in 2010 — as he led me on a tour of the crime scene.
“I think about it every day,” he said. “It never goes away.”
