What exactly did you see? The killing from the shooter's angle?
Yes.
Yup
Yes, like a first person shooter in a video game. Just the gun and his hand holding it, and then him firing 3 rounds at her.
Yes, he was holding the cell in his left hand and shot with the right hand.
Yeah, there were 2 videos posted, one when he’s walking towards them while they were filming, the other he’s watching the interview, positions himself right behind the cameraman, aims, and fires several shots, first at the reporter, than others, before video stops.
