Whittington shot a bird and went to retrieve it in the tall grass, while Cheney and the third hunter walked to another spot and discovered a second covey.
Whittington "came up from behind the vice president and the other hunter and didn't signal them or indicate to them or announce himself," Armstrong said.
"The vice president didn't see him," she continued. "The covey flushed and the vice president picked out a bird and was following it and shot. And by God, Harry was in the line of fire and got peppered pretty good."
Yep. I'm pretty sure that says behind.
