Well, we know who play him in the movie...
I hope it was a Pennsylvania Trooper with a wicked left hook that set his beak over to that one side.
Piece of sheet.
Your hope is all too likely a fact.
If it was a trooper that broke the murderer's nose, it is also surely a contributing factor to why one is dead and another lies dieing.
Police abuse only incites such people to violence.
A broken nose does no good and much harm when a long stay in a mental institution is what is actually needed.
