There had to have been multiple people involved and more than one shooter. Oswald was involved but wasn’t alone. E. Howard Hunt told his son on his deathbed that LBJ was behind it. A lot of facts were in the Stone movie, even if Stone is a fruitcake: the prostitute thrown from the car on the highway from NOLA to Dallas. Oswald’s defection, marriage, redefection. The magic bullet theory. JFK’s head snapping backwards and witnesses (many) saying the shots came from the grassy knoll. Too many things wrong with the Warren Commission report.
And I’m a realist, a conservative, a veteran. Do I know the answer? No, but I know it didn’t go down with Oswald as a Lone Wolf.
Someone did a “stabilized” version of the Zapruder film.
You plainly see Kennedys head move back, towards the left, as if exactly away from the grassy knoll.
