The film wasn't clear what those guys did to be standing before a judge in court. Maybe poaching, night hunting, illegalities of one sort or another? They weren't in court for lawful deer hunting. If they were then some righteous indignation would be understandable.
What I saw on the video was this:
Judge was in the process of recusing herself from the proceedings because of her bias against hunting and hunters, and the guy wouldn't shut up for a few seconds and just take it. That's what happens when a judge is in a bad mood, but I don't see where any other judge anywhere should be expected to have put up with backtalk from a witness. Looked more to me like he was bullying the judge.
If there is outrage warranted by viewing this video, there must be something more there that I failed to see. And why were they there? That's the part going unexplained.
