Yes, I would agree with that, testimony alone probably wouldn’t be
enough to be convincing. I really did that study to see how that type of
testimony would align with the other study on analyzing voluntary reaction
time from early Zapruder film reactions to back calculate a stimulus
occurrence time.

As to the time spacing of shots two and three, I think this suffers from a
similar thing I worried about for the location of the first shot when
looking at just general first shot testimony (i.e. variability of
testimony). Without a given anchor point or a bench mark, there is no
definitive standard/reference/definition of how much people meant when
they said shot two and three were closer together. Although perceived
closer together, this could make it hard to conclude exactly how much they
were separated from the first shot.
Here is Governor Connallys opinion about what closeness in shot timing is:
Mr. SPECTER. What is your best estimate as to the timespan between the
first shot which you heard and the shot which you heretofore characterized
as the third shot?
Governor CONNALLY. It was a very brief span of time; oh, I would have to
say a matter of seconds. I don't know, 10, 12 seconds. It was extremely
rapid, so much so that again I thought that whoever was firing must be
firing with an automatic rifle because of the rapidity of the shots; a
very short period of time.
It appears that for Governor Connally, the spacing between the first shot
and the third (the two shots he heard), was 10 to 12 seconds apart and he
defined this as extremely rapid.
Independent of all this though, in looking at this post I thought of
another possible explanation for last two shots bunching closer together
in some testimony: if there is a tendency in human nature to associate
event timing closer together based on an awareness that the events you are
hearing are interrelated.
That is to say if the first explosion was not recognized or associated with a shot at all, but then awareness that subsequent explosions were shots, I wonder if there could be a natural bias to not associate the first noise as close to the latter ones, and only later when realizing the first noise may have been a shot, trying to redefine what it was and when it was heard might result in some regression back in time because it was not originally associated with the later ones.
I’m not sure this possibility has ever been studied, but I took a quick look at a couple of testimony examples I can recall along these lines.
Bonny Ray Williams, James Jarman, and Amos Euins. These all later said they thought the last two shots were closer together and first sound was not a gun, but rather a firecracker or motorcycle backfire. Realization started to set in during the second and third explosion that shooting was likely going on. Here are some testimony snippets.
Bonny Ray Williams:
And then the thing that happened then was a loud shot--first I thought they were saluting the President, somebody even maybe a motorcycle backfire. The first shot--there was two shots rather close together. The second and the third shot was closer together than the first shot and the second shot, as I remember.
the first shot-**I really did not pay any attention to it, because I did not know what was happening.**
Mr. DULLES. I have one question. You have referred to three explosions that--one you thought was a backfire or a firecracker.
Mr. WILLIAMS. Yes, sir.
James Jarman:
Mr. JARMAN - After the motorcade turned, going west on Elm, then there was a loud shot, or backfire, as I thought it was then--I thought it was a backfire.
Mr. BALL - You thought it was what?
Mr. JARMAN - A backfire or an officer giving a salute to the President. **And then at that time I didn't, you know, think too much about it.**
And then the second shot was fired, and that is when the people started falling on the ground and the motorcade car jumped forward, and then the third shot was fired right behind the second one.
Mr. BALL - Were you still on your knees looking up?
Mr. JARMAN - Well, after the third shot was fired, I think I got up and I run over to Harold Norman and Bonnie Ray Williams, and told them, I said, I told them that it wasn't a backfire or anything, that somebody was shooting at the President.
Amos Euins:
Mr. SPECTER. Amos, when you heard the first shot, did you have any reaction or impression as to where the noise was coming from at that exact time?
Mr. EUINS. No, sir; not at the exact time. You know, because everybody else started looking around. ** So I just started looking around, thinking it was a backfire, just like everyone else.**
Those three dismissed the first noise as inconsequential, and only later determined it was a shot and also fairly different in timing from the final two.
Now let’s look at two individuals where they said they had the first noise pegged as a shot right away. Win Lawson and Governor Connally. In this case both of these individuals were very certain of what they heard, a gunshot, and they effectively had the shots nearly spaced equally. Win Lawson did think the third shot was a little closer to the second shot than the second was to the first. Governor Connallys timing is by difference: putting the timing from shot one to three as at least about 10 seconds, and using Zapruder film evaluation of shot two to three being about 4.9 seconds. Like Win Lawson, this also would put the third shot just a little closer to the second shot than the second was to the first.
This data does tend to align with the hypothesis I mentioned, but obviously much more research would need to be done to discern a trend. There may even be other explanations, but this is at least one alternate explanation to some perceived shot spacing other than additional shooters stationed somewhere around the Plaza using silencers on guns.
