That’s all you have?
Wasn’t there a police motorcycle with its radio on that captured the sound of gun fire?
Here’s a real good page, at least in my opinion.

House Select Committee on Assassinations,
47% ear-witnesses heard gunshots from Texas Schoolbook Depository Building
20% ear-witnesses heard gunshots from Grassy Knoll
29% ear-witnesses heard gunshots from “Other”
4% ear-witnesses heard gunshots from “Two Directions”
I think the last stat is especially significant because that means 96% think at a minimum, the gunshots come from one direction, highly in favor of the lone gunman thesis. (Let alone, for the record, almost half hear the gunshots from the Texas Schoolbook Depository Building)
Next Stat, number of gunshots is on that webpage as well:
81% say 3 gunshots, under 3 gunshots, 12%, 4 or more gunshots heard by only 5%.
These two stats totally sink the multiple-gunman theory. Now, I am open minded but I do say, at least in regards to the witnesses themselves, the Oliver Stone/Jim Garrison/Jim Marrs scenario does not seem plausible.
