Do you buy the limo driver theory, then?
The limo driver was William Greer. He was born in Northern Ireland to Protestant parents. Reportedly, he was a member of the Orange Order in his native country. The Kennedys were the most prominent Irish Catholic family in America, if not the world. I don’t know if Greer fired the kill shot. The picture allegedly showing him turning toward President Kennedy and firing a pistol is unclear. However, can you imagine a Secret Service agent protecting Barack Obama who had been a member of the Ku Klux Klan or any similar white supremacist group? At a minimum, selecting him to be anywhere near shows extreme incompetence on the part of the Secret Service leadership.
