It seems lore like. A man shows up legally drunk, with a firearm and one way or another discharges a round in the direction of the cops..cops return fire.
I see your point but since no one knows when he shot it leave a lot to guess about.
I have killed a lot of cows all with a 22. Never shot one in the gut and never had to use a second shot. Drunk or sober if they had let him do the job they called him to do we would not be having this discussion.
