Rittenhouse didn't try to engage with authorities. He was there and had a firearm to defend himself against insane lefties who were demonstrably physically attacking those with whom they disagreed.

Are they going to claim Pretti armed himself to defend from some mythical hordes of ravening ICE supporters? He armed himself and was repeating his actions of a week earlier in which he got into physical altercations with the lawful authorities who have shown no proclivities to attack/harm those who are only protesting.
