But you can still get in plenty of legal issues. If I decide to get into a boxing match with some dude I hate on the street, we could both get arrested for that. And one of us could get seriously injured or killed, and the other guy is now in serious legal trouble.The point is, if I as a grown man fight off another grown man and I don't use and weapons then I did meet force with the same level of force, in such a situation we're both grown men and we both aren't using any weapons.
