Well he is a crazy guy in rage... Crazy people in rages do crazy things that unarmed bar guy he preemptively vent that guy at the bar.
But your point stands.
A countering question. What would have happened if Joshua would have broken Rigg's neck..? Would the cops engage Joshua H2H after seeing the danger of getting into it with a guy who has shot two of their buddys and then broke/killed their best H2H guy with his bare hands, or would they just have shot Joshua...?
Anyway Joshua didn't look very 'defeated' when he was struggling with cops to successfully acquire one of their firearms to me.
He looked defeated though after he took gunshots from Murtaugh then Riggs.
Anyways.. A significantly overlooked fact:
That fight should be discounted as a H2H encounter, on the grounds that they used weapons. 🙂
