This taxi drivers video seems to indicate two guns from the distance of the sounds, and muzzle flashes on a much lower floor.
She also picked up people who someone had a broken leg when they got in but not when they got out. Miraculous taxi ride! And they weren't particularly happy she was videoing.
full view of earlier vid;
I can understand why they would claim a broken leg, AND why they would be afraid of video...people panic
hell, they wanted the cabbie to drive through the cab
Agreed on the panic.
Interesting comments on the video on YouTube. A lot talking about how the shots sounded like a belt fed light machine gun. But that's just speculation, not facts we can find like you're asking for.
could also be a drum magazine
some of the bursts sounded longer than a mag would; you's need to slow down audio and count the shots
