but if you analyze the video time stamps as above poster referenced you will likely see 8 casing officer is looking wider than the 5 casing guy and appears to also be looking on the other side of the roof which does have something black on it as well.
I watched the 8 count video clip. Looks like the same person counting as in the 5 count video clip.
I think the 8 casing count counts casings past the peak of the roof, while the 5 casing count maybe only counts casings on the same side of the peak as the body.
So Crooks might have fired the 3 and 5 from different positions and/or stances, which could account for the difference in sound in the close-to-Crooks recordings.
If I remember correctly, this possibility was mentioned as one alternative by the Peak Prosperity guy.
So best evidence favors one and only one shooter toward the stage, I guess.
