personaly i think the man was just a fecking bully,bulled himself up in prison with what he was going to do and went and shot unarmed woman and boyfriend ... very big fella...then shot a copper who was someones brother father and son... could have been yours...then reality poured home and he had no alternative but to shoot himself.living like rambo, pull the other one just shitting himself in a bush , trying to do the honarable thing.
