When the cover-car moves, clearly she fires again...
I don’t believe that’s when it occurred. Going frame by frame, it appears she initially fired at least 2 rounds, not one. I don’t believe she fired again once the suspect dropped the gun and was on the ground, even though the suspect was close to it.
Still reviewing. At 0:25 right after the initial shot, it appears she fired again, just as the suspects is in the process of falling to the ground.
When the cover car moved, she moved toward the suspect and appears to motion with her gun for him to roll over on his stomach which he complied, as she walked up and kicked the weapon away. It’s at 0:25 when it appears she fired #2 as the suspect is falling due to the 1st round in the 10 ring.
