I'd reckon the shotgun issue is more a case of the guy getting complacent with his unloading procedures. Maybe the guy shot till he was too tired to check he was clear (lesson there). Maybe he's in too much of a habit and thought he was unloaded (also a lesson there). Either way that bloke should buy a lotto ticket because a car you can replace. What if that was a baby in a pram....
