The Corpus Christi Caller Times (they broke the story) has a reenactment of the Cheney shooting. George Gongora, an "avid shooter" fired at a paper target 30 yards away. Here’s the result:
"We can pretty much see that at least over 200 BBs have touched this area right here," [George] Gongora said, motioning to the face and torso area of the target.
There’s video too! (No lawyers or Republican donors were harmed in the making of this film.)
