You have totally swallowed the AR15 nonsense which is your right. Not a single witness reported that any agents fired any weapon and Donahue's research seemed like a weird case of tunnel vision without any compelling evidence whatsoever. If there's a rear head shot, where's the exit and where did it occur? I don't trust the Zapruder film since nearly all the medical witnesses reported a large hole in the rear of the skull. Your question about what is louder is rather ludicrous and your handy hint made no sense. I've been to Dealey Plaza and I've carefully studied the acoustics evidence. Keep in mind that many witnesses directly below the depository reported shots from the railroad yards while others heard shots from above them. I believe shots came from multiple locations and to believe otherwise necessitates ignoring an enormous amount of evidence.
Hickeyists make up i think 27% of jfkists.
Hickeyists left this forum a long time ago, & it is now owned by LNist & CTists.
Hickeyists agree that Oswald was a lone nut, but that he didnt fire the fatal shot.
Hickeyists agree that there was a coverup, but that the main coverup was re Hickey's accidental homicide.
Hickeyists believe that Hickey fire one shot me myself i know that he fired an auto burst.
I agree re multiple locations (1) from the 6th floor window (2 shots) & (2) from in the Queen Mary (4 or 5 or 6 shots). No other shots/locations -- not the grassey knoll, not the paling fence, not the manholes.
I reckon that if u fired an AR15 at a nearby flat fence then the echo would be louder than the direct sound.
Hence many earwitnesses would have been confused.
But i have never studied any of the acoustic JFK stuff.
Re evidence, i bort JFK THE SMOKING GUN (Colin McLaren) & MORTAL ERROR (Bonar Menninger)(Donahue) about 30 bucks each these detail much of the witness stuff.
The Zapruder film has not been doctored. Are u going to believe the witnesses or your lieing eyes?
