according to this: https://www.cbs58.com/news/kyle-rittenhouse-trial-enters-week-2-survivor-testifies Rittenhouse was NOT randomly shooting at people. There is also video evidence that shows him RUNNING AWAY from people chasing him. The people chasing him then attacked him. One of them had a shotgun, I believe, pointed at him. According to HIS OWN TESTIMONY, Grosskreutz was pointing his gun at Rittenhouse when Rittenhouse fired at him.
While there is plenty that Rittenhouse is guilty of, murder is not something he planned to do. By the time he shot his weapon, he was firing in self-defense.
