I think you almost have to take him back. He was found not guilty on the worst charges. Not taking him back would be like Bo saying "I know a jury of your peers found you innocent, but I still think you did it so F off."
He was drunk in a bar that he was not supposed to be in, was involved in an altercation, admitted that he poured beer over a woman's head, refused to follow the lawful orders of police officers, resisted arrest, assaulted police officers and deliberately damaged the officer's car. These are all by his own admission or by guilty verdict.
Not enough for you, Dave? I would have been very pleased if he wasn't invited back. At the least he should have to complete substance abuse and anger management programs before he can come back. Who cares if he can help the team?
