From the people on the scene, we've heard behind and behind on the right. Since he was shot on the right side, that would tend to indicate he wasn't directly even on the right, but back a ways.
Folks can try to distort that to make it sound like something else, but it is obvious to anyone who isn't trying to avoid it that the VP wheeled to the right beyond the zone of fire and fired.
I'm out.
OK. Another geometry lesson: The human body is not a Möbius strip. It has two sides. A front and a back. Whittington could have been shot on the right side and yet been to the right of Cheney.
How? He might have been turned around.
The CSI guys you're not.
