I've never thrown a punch in my life but I have been punched.
There's a reason why the Rittenhouse case is so important: if Binger manages to get a conviction based on his arguments, nonviolent people are perpetually fucked.
It's not that it's inconceivable that I could win in a fist fight if I needed to. I mean, I did manage to break a dude's wrist during a one on one drill at football practice almost twenty years ago. I'm not the weakest guy on the planet; but, I really don't know how to fight.
Nobody knows what a bad guy looks like. Nobody knows what a stranger's abilities in physical combat are. What's more, the person who is hesitant to fight is less likely to win than the person who wants blood.
Sure, I could see that Joseph Rosenbaum is seven inches shorter than me and I've got a reach on him; but, do we really want the law to say that if Somebody like Rosenbaum beings acting like a violent prick to me that I should have to let him throw the first punch and, if he does, trust that I can beat him even though I've never been in a fight?
