The two men had no idea if Rittenhouse had committed violence.
They assumed that he did and attacked Rittenhouse.
That's called vigilantism.
“That’s called vigilantism.”
To me that is the sad part about Kyle being labeled a vigilante. It was these two morons who wanted to kill Kyle without knowing all the facts of the first shooting that are the vigilante. They would have not been harmed and likely no trial, if they had just followed and reported Kyle to the police.
