If Greer had shot JFK, someone in the crowd – some less than than 10 feet away – would have said something, SS agents and others in the know would have whispered about this for years, rumors would have floated around Washington and Nellie Connally, whom I knew personally, would have talked. The truth is that none of this happened.
In fact, this issue never came up until about the mid-1980s when William Cooper latched upon a hypothesis of researcher Lars Hanson of California, who, upon viewing a bad 4th or 5th generation copy of the Zapruder film, speculated that the driver turned and shot Kennedy. Upon careful inspection of the film and further reflection, Hanson denounced his own theory but this did not stop Cooper from selling bad (some so bad there was no color) copies of the Zapruder film and continuing to claim the driver shot JFK even though Hanson and several other JFK researchers, myself included, warned him not to do so because the claim was false. Cooper would not listen and sucked in many other credulous researchers until he was killed after shooting at police who came to serve him a warrant in 2001.
In addition to his claim that Greer shot JFK, Cooper also claimed that all the nearest witnesses to the JFK head shot were dead within a few years of the assassination, a claim demonstrably false. So, what exactly are you seeing in the Zapruder film?
It is true that Greer turns to his right and looks back at JFK at the time of the fatal shot…a somewhat suspicious circumstance as Greer claimed he never looked back and did not know the assassination taken place until Roy Kellerman, the agent next to him, said. “Let’s get out of here, we’re hit.” Greer then faces front and the car accelerates.
In those days, it was customary for men to wear their hair ‘greasy’ and Kellerman’s hair was especially slicked down that day. Watch Kellerman closely and you will see the sunlight glinting off the top of his head. You will also notice that the “pistol” moves simultaneously with Kellerman’s head. Also notice a few frames earlier when the sunlight gleams off both the top of Kellerman’s head and Greer’s. As Greer turns to his right, Kellerman bends forward slightly and the sun fully catches the top of his head. The resulting bright highlight indeed is a horizontal L shape and could be misidentified as a gun.
But notice as Kellerman’s head moves, so does the shape. The brief flash seen is simply the sunlight reflecting off the metal rim of the bar frame for the privacy window used when the top was on the car. That day, the top was down and the privacy window rolled down.
I have studied first-generation clear prints of the Zapruder film and it is apparent that while it may be questionable as to why Greer turned and looked back at Kennedy and then could not recall that fact for the Warren Commission, at no time did his two hands leave the steering wheel of the limousine. There are plenty of real conspiracies out there without dragging this old wheezer up again.
