Yes, just watched it again, he backed into view. I never said he backed out of view, it's not very clear. It is pretty plain that he is backing up as he shoots the dog. You can't seriously argue otherwise.
Oh? When the dog left the car Hall is backing up while the dog is not headed towards him like you said. Then they both go out of view."
Then you say Hall is backing up when comes *back* in view of the camera. That's absurd. If moving backward would take him out of camera range, it certainly wouldn't put him back in camera range from where he was positioned. Look again at the direction Hall headed in when the dog left the car. He is moving to the left from his right.
I'm done with the subject.
