Robin Bain was able to overcome and incapacitate Stephen without having any injury inflicted on his person


The Defence describe Robin Bain as a walking cadaver of a man.  While he did weigh more than Stephen it is hard to imagine that this supposedly clinically depressed man had the motivation let alone the ability to fight off Stephen while at the same time not having any injuries inflicted on his person.  Nevertheless we'll be generous and give it a 50/50 chance,
