You misquoted Hickey.
?? If you are suggesting that I misrepresented what Hickey said in his statements, please read them again because you have not read them correctly:
November 22, 1963 statement:
"The president was slumped to the left in the car and I observed him come up. I heard what appeared to be two shots and it seemed that the
right side of his head was hit and his hair flew forward."
In his November 30, 1963 statement Hickey explains in greater detail the shot sequence:
"The first shot of the second two seemed as if it missed because the hair on the right side of his head flew forward and there didn't seem to be any impact against his head. The last shot seemed to hit his head and cause a noise at the point of impact which made him fall forward and to his left again."
His first statement was different in key aspects. Kinney reiterated what Hickey stated that a bullet impacted JFK's head and his hair flew forward.
There is no material conflict between Hickey's two statements. Read them again, carefully.
In both he says there were three shots. In both he describes the first shot and then describes the next two. In his second statement he said the last two were in rapid succession. That does not conflict with what he said in his first statement. It just provides more detail. In his first statement he stated that as a result of those two shots, he observed JFK's hair to fly up and also observed an impact to his head. In his second statement he clarified which shot impacted his head and which one caused his hair to fly up. He was able to discern that they were separate and distinct shots.
Altgens in his first press news bulletin read live on the air for NBC minutes after the assassination stated there was there was only two shots.
Do you have a quote? In his WC testimony he was clear that his z256 photo was after the first shot and before any other. He could vouch for the first and the last but was not sure how many were in between. That to you means he heard only two?
The HSCA explained the timing of the echoes to the original shot. Maybe you were unaware of this.
HSCA Accoustical analysis
All observers rated the rifle shots as very very loud, and they were unable to understand how they could have been described as a firecracker or backfire. Only the pistol, which was subsonic, produced a moderate loudness.
In the early sixties a firecracker that was very popular before it was banned was the cherry bomb. It was deafening. They were banned in 1966. By 1978 they had not been around for over a decade so when people were asked whether they thought the rifle sounded like a firecracker, they could only compare it to the firecrackers they knew, which were things that went "pop".
