I watched all the videos I could find very, very closely, and there are a lot of videos from several different angles. Self defense. Clear as day. Rittenhouse is being chased by a man who was spotted on an earlier video being an an aggressive, belligerent lunatic. The nut threw a flaming object at Rittenhouse who was fleeing from his attacker at a sprint before he turned and fired. The next two were shot as Rittenhouse was on the ground, being attacked by multiple assailants, and retreat clearly wasn't an option. Anybody who is willing to take an honest look at the videos will see that Rittenhouse had two options- 1- self defense via lethal force 2- suicide by mob beating Take yer pick.
