Was he stupid to be there? Probably. Does being stupid negate your right to self defense? No. If the politics were swapped, it was someone who supported BLM who gunned down a few Trump humpers, I would say the same thing.
If you are attacked, and you have attempted everything short of lethal force at your disposal, shoot the attacker.
Rittenhouse was attacked, he attempted to retreat (This is extremely important), he was chased down, he kept trying to retreat until he was grabbed by his attacker who had a weapon (A chain is definitely a weapon). He then turned and shot.
He did everything he could to avoid lethal force before employing it.
Him having the option to have not been there is just irrelevant noise from people trying to distract from the facts of the case. His reason for being there is irrelevant once he started retreating. None of it matters. He tried to escape the situation he was in at the time. He was unable to and he defended himself. That is what the evidence shows.
I would be MORE worried about the precedent that is set if he is convicted. It would make self defense in Wisconsin almost impossible to use as a legal defense for any reason. We do not want to strip the right of self defense from the people. That just enables people like Rosenbaum to attack more people, it enables rapists and muggers. After all, you shouldn't have been outside in an area you knew was high in crime with a weapon...
Hit the nail on the head chief.
