Welcher used transfer material and body positioning to demonstrate possible arm-contact locations.
What the record shows
He wore comparable clothing and positioned himself near the vehicle's right rear. The demonstration addressed contact areas and low-speed movement.
Limits and disputed context
It did not measure O'Keefe's actual posture and was not a human impact experiment at the alleged reverse speed.
