2) Why didn't everyone hear your beloved "shot pattern"? Funky acoustics?
They all heard the shot pattern that occurred.
Not everyone paid attention to the rhythm of the shots. Of those who recalled a pattern without prompting almost all said that the last two were closer together.
Those who didn’t notice a pattern, when asked said they were about equally spaced. James Romack was asked about the spacing in his WC testimony on April 8, 1964:
"Mr. ROMACK. Oh, they happened pretty fast. I would say maybe 3 or 4 seconds apart.
Mr. BELIN. Were they equally spaced, or did one sound like it was closer than another one in time?
Mr. ROMACK. It sounded like to me that they were evenly spaced. They rang out pretty fast.
Mr. BELIN. Have you ever operated a bolt action rifle?
Mr. ROMACK. Yes, sir.
Mr. BELIN. Do you own one?
Mr. ROMACK. Yes, sir.
Mr. BELIN. Did it sound like the shots were faster than it could be operated with a bolt action rifle?
Mr. ROMACK. No, sir."
A few did not offer a recollection about the shot spacing in their initial statement but, later, in describing the shots gave their opinion of how they were spaced. For example, Steven Wilson said this in his detailed statement to the WC on March 25, 1964 (22H685):
“In a matter of ten seconds or less after car and occupants were obscured from my view by the trees, I heard three shots. I am positive there were three shots, no more and no less. It is my opinion there was a greater space of time between the second and third shots than between the first and second. The three shots were fired within a matter of less than five seconds”.
Note: Wilson was observing from the third floor TSBD on the south-east corner almost directly below the SN. If the first shot had occurred early before JFK passed under the oak tree, as is required by the SBT, Wilson’s view of the car would not have been obscured by a tree. So Wilson’s observation that the shots occured after his view of the car was obscured by a tree means there was no early shot.
