And picture a gaping chest and shoulder wound in the victim, one that required an immediate plasma delivery to aid in blood coagulation. Go ahead and just picture the fiery pits of the deepest hell while you're at it, because that's the scene we're trying to paint Bush in here.
Now, if you were a Japanese soldier fighting for the empire, maybe you'd give pause when coming upon a guy so almost-dead that he's getting a blood transfusion.
