With all the evidence, I too wouldn't be surprised if he gets charged with assault and carrying a dangerous weapon.I too am glad there was someone to intervene. It could have been much, much worse. That dickhead just screwed himself, didn't he? I'm sure the judge will have something to say about his "I tried to walk away" comment... Can't walk away if you are perched on top of someone while beating them with a club.
hope he gets the book thrown at him
