Another idiotic statement. The mob had moved as a mob, broken windows and doors as a mob, from the time they entered the building. There was no need for her to tell the mob to continue to be a mob; it was assumed.
The other police didn't shoot for two reasons: One, they were far too close to engage with guns. I can tell you as a trained martial artist I can tell you that there's a good chance they would have had their guns taken from them, had they drawn them. The crowd is on tape yelling to take their guns and to use the cops own guns to kill them. The cops on the side of the barricade with the rioters did the only thing they could do: retreat. The second reason for not shooting is that there was still a chance that the rioters would not cross the barrier. When Babbitt crossed through the window, that option was gone and the only choice left was to shoot.
