Apology accepted. I was a little upset for a moment but I'm over it now.

Does it depend on what did or didn't happen to his daughter? I don't have a problem with someone knocking seven shades out of someone who fucks with their kids either. But we're not talking about morality here.

Robinson's problem is that he got arrested and the other guy didn't right? Between Robinson and the Police we know (Because Robinson said so) that he was trying to stop the bloke from leaving until the police arrived. A citizens arrest if you like. The Police say he punched the bloke in the face a bunch of times and (I think) gave him a bloody nose. UK/US it doesn't matter. Are you allowed to make a citizens arrest? Yep. Are you allowed to punch someone in the face a bunch of times in the process?
