Nobody said the shots came from the "right" behind him. He actually said "I thought the shots came from directly behind me."
You just don't want to believe him.
Where did I use the term "Right behind him"? I never said that. You are missing the point, completely. I
**DO** believe him, it's you who doesn't believe him. You are trying to change what he says, when you said " Note how the angle of looking at the chalk board changes at about 17 secs. so that the curve appears to be more elongated.
It's called editing to suit the point of view of the editor."
That is why I posted the clip in its entirety because when the camera looks straight at the board he drew the lines on, we can clearly see that he is talking about to his left and behind.
