To put it very seriously, I don't ever want to be put in the position of making this sort of judgement, to intervene in a secondary event.
In a primary event I will have all available information. It will be me and the guy who is presenting as a threat. I may still have deficient information, but It's all my decision to make based on whatever information he is providing.
If I happen on the second hand event of two people whaling on each other with clubs and all I have is lethal implements, WTH can I do? Nothing. Call for help. Let it play out, interfere if one goes down and the other keeps attacking. I'm going to feel really bad if the loser spends two weeks in a coma and then dies because I couldn't intervene.
