“This is where we disagree. All but one of these items of evidence fits very well with a frontal-gunman scenario. I agree that the SS was deeply involved in cover-up activity, but I don't think it had anything to do with Hickey. “
“I see no credible evidence that Hickey fired his gun. Kennedy loyalist Dave Powers was in Hickey's car, and Powers said there was no way he could not have heard Hickey's rifle fire. In fact, none of the occupants in Hickey's car showed any reaction that would be consistent with having just heard an AR-15 fire from their car. I have fired several AR-15s--they are very loud.
Hole in the back of the head, not frontal. Explosive nature of JFK’s head, either direction. Hinkleys behavior after and the cover up, why would the SS cover anything up if they didn’t do anything, that makes no sense. Smoke smelled in the motorcade, could not have come from forward because the shot would have come from the grassy knoll and the wind direction would not support that.
Two witnesses saw Hickey with the AR 15 and one said he had thought Hinkley had fired it and both of these witnesses were SS Agents. There were more witnesses that saw Hinkley with the AR 15, one was on the overpass and he thought Hinkley fired it.
A 5.65 mm round came from behind and based on Donahue’s study it came from Hinkley’s direction. Hinkley was holding the AR 15.
Powers was running towards JFK’s limo and was grabbing on to the handrail on the back of the limo at the time of the head shot. So he was in no position to witness the shot.
I have fired the M16 also and with the flash suppressor on them they are about a third of the noise level as an M14, granted my memory going back over fifty years is not that sharp but I do remember when I first fired the M16 after months of training with an M14. They are so different in the noise level.
So based on all of this I am saying that Files and Hinkley fired frangible rounds at the same time and probably added to the intensity of the head "explosion" and the jerking backward of the head.
