Mary, you saw what they wanted you to see in that brief clip, and they knew you would assume some sentient presence in what were in fact a few reflex moves, pure lower brain stem stuff. That was apparently a tiny reflex edited from a four hour tape of her motionless vacant gaze. By surgically inserting a device through her abdomen into her stomach they were prolonging a state that, before the type of surgery was possible, would have rapidly resulted in the death of a woman who couldn't eat or drink.
