I have listened to numerous videos repeatedly. What I have heard could be explained by echoes, and one guy using 2 different kinds/calibers of weapons while shooting out of two vantage points that each faced (slightly) different directions.
But, if someone told me there was a second shooter at a different location, I would not be surprised at all. There are instances in the audio that, while they could be one person as described above, they could also be two different shooters.
I’m not surprised that, listening to it all happening live, in the fog and chaos of it all, even some LEO might have thought there was more than one shooter.
Good points.
Two people could have coordinated it and rotated from window to window.
One of the first things I picked up on was the sound of what I recognized as possibly an M-60 machine gun. Others here agreed with me. That was clarified later by the modifications made on the guns.
WHOSE FINGERPRINTS were on all those guns??
