I found the original video, he makes the case that there where 2 or 3 shooters.In the video he's analyzing, the second volley of 5 shots does sound very different than the first 3. But I do find it odd that he doesn't even mention that in the video he's analyzing, for the first 3 shots the camera is facing one direction, then the cameraman turns around 180 degrees for the next 6 shots. I would guess that would affect the acoustics and how the shots register on the phone's microphone... (Again though, sounds like 5+1 shots in the second volley, not 5+2.)
Here's the video:Seems at this point, after all the discussion, it's still possible that there was only one shooter, Crooks, although given the various suspicious details and precedents, it's highly unlikely that he acted alone. Maybe that's where we'll have to leave it until more data comes in, assuming any does.
Some points:
The first three shots come from the same location/have the same time signature. About 400-450ft (~120-130m)
Based on the footage of the first shot hitting the railing, he estimates it's a rising shot. Meaning it was fired upwards (from the window)
He backs this up with audio analysis from a video from a different location (nearer the shooter). The first three shots have no echo, where as the other shots do. Meaning the first three shots where probably from inside.
There is additional discrepancies with the rapid fire section (shots 6-9) in that they again don't have echo's - and are most likely 100ft behind the first (two) shooters.
Looking on google maps, this would put the third shooter in the yellow area I've marked:
In conclusion:
