That video has it all.
The gun wasn’t pointed at her when it went off.
Darned if it doesn’t now look like a staged shooting, complete with a gun loaded with blanks.
It appears that the “shooter” pulls the gun to his left before pulling the trigger. I think he might have been scared he was lied to and the rounds were real. So he aimed to his left just in case.
While there is plenty of things that seem strange, the aiming of the gun is not.
There’s are four windows, with the middle two being in the double doors. The shooter is first aiming at the middle windows, toward protesters that haven’t been kept away from the doors, which was proof the cops were apparently told to let them eventually enter, (with select operatives breaking windows).
But the protesters at the double doors were not forcing their way in. He swings his gun toward the last window as he sees her coming through it, with his aim being at her head, which was probably a foot forward of the window when he shot her. So at that trajectory he would have been aiming about 6” (approx) forward of the corner where the window frame meets the hallway wall. Hence the swing of his aim.
Add to that the fact that these camera phones exaggerate distance, requiring some zoom applied to get a more accurate pic/video.
