“Speer seems to think there was actual "smoke" seen on the knoll. His Donahue/Hickey analysis is more grounded. Hard to argue with photos and film.”
Hard to argue with a bunch of witnesses also.
“Could have been car and motorcycle exhaust from when the front of the motorcycle accelerated out of the kill zone. Knowing a gun had recently been fired might have subconsciously "colored" any similar smell.”
People always try to use this argument but the two gases are distinctly different. Gun powder has sulfur in it and car exhaust does not. There were several people with lots of weapons experience in the witness list, they know the different smells.
“Seems to me she's assuming certain things happened.”
Hard to say what she was thinking being under fire and all. There were plenty of other witnesses that thought Hickey had fired the gun.
“I take it you mean Agent Clint Hill. Powers was sat on the passenger-side jump-seat.”
I did mean Clint Hill
“How convenient. Can only show you the water, not make you drink.”
Sorry but it is blurry as hell.
“I personally think a Carcano 6.5mm bullet could account for the trail of fragments in the President's skull.”
Now you are a ballistics expert? Look I did a rough comparison between FMJ fragments and frangible fragments. In one hand you have a few pebbles and in the other hand you have20 or so coffee grounds, they are totally different. Ballistics expert after ballistics expert stated that FMJ rounds do not fragment when they hit a skull.
“And I don't believe there was "gun smoke" seen on the knoll or at the fence.”
You don’t believe it! Well there were plenty of witnesses that did so your “belief” doesn’t count.
“The collapse of the Donahue/Hickey Theory isn't much important.”
Dream on, it didn’t collapse, until you can tell me where the gun smoke came from and where the frangible round from the back came from, it’s alive and well.
