As the years went by, the former Secret Service agent later told a documentary, he returned to Dallas, eventually coming to the conclusion he could not have saved Kennedy's life.
On 22 November 1963, Clint was assigned to protect the president's wife, Jacqueline Kennedy as they rode a motorcade through Dallas, Texas in 1963.
THE brave Secret Service agent who leapt onto John F Kennedy's limousine after he was assassinated has died at the age of 93.
After the first shots rang out - directly hitting Kennedy - Clint heroically dived towards Jacqueline and climbed into the limo as the shooting continued.
He had become convinced that he could have saved Kennedy's life and shortly after his retirement told CBS 60 Minutes that he felt responsible.
