The mention of Rolling Stone and anything to do with guns and then bring up lies is probably being entirely redundant, but it doesn’t hurt to make it explicitly clear.
While patrolling the streets, there was gunfire that resulted in some of the Black Lives Matter protesters thinking Rittenhouse was attacking them. They charged Rittenhouse, and he opened fire, killing Joseph Rosenbaum and Anthony Huber and injuring Gaige Grosskreutz.
That’s not how it happened. You can watch the video of every shot fired and see for yourself. The gunfire was as the “protestors” had boxed Rittenhouse in between some cars and were closing in on him. One of those attackers fired the gun into the air a few dozen feet from Rittenhouse. The shooting of Huber and Grosskreutz were a minute or so later as Rittenhouse was attempting to reach the safety of the police and the attackers caught up to him after he fell. They struck him with a skateboard, kicked him in the head, and pointed a gun at him. Each person shot was an imminent threat of permanent injury or death to Rittenhouse.
