Did you even watch the video? He was running away each time he ended up shooting someone. First time he tried to run but got trapped between some cars and was getting rushed by a mob.
Second time he was running at a good clip and he was hit a few times, but didn't do anything until someone hit him in the head with a skateboard and he fell over. When that person came in to hit him a second time while on the ground, he shot them.
The third was while Rittenhouse was still on the ground. The other person pulled a gun on him but when Rittenhouse pointed his gun first, the third person held his gun up and backed away. When Rittenhouse tried to stand up the other guy aimed his gun at Rittenhouse, and Rittenhouse shot him.
All three times people rushed him while he was in a vulnerable position, the second person assaulted him with a deadly weapon, and the third drew a gun on him.
Rittenhouse is a dumb rightoid who put himself in the wrong place at the wrong time. That doesn't mean that he is not allowed to defend himself from obvious threats to his life. As for anyone intending to protest without getting blasted, a quick tip: don't fucking attack people who are running away because it makes it look like you're trying to kill them.
What exactly are you arguing for? That the coyote should avoid traps? That the hunter shouldn't be laying traps if they don't want to get bitten? What is it?
Fighting back against a perceived threat does not grant the threat justification in their violent actions, nor does it remove legitimacy from the coyote for defending itself from a perceived threat.
Rittenhouse entered the woods, laid a trap, approached the trapped animal, was bitten, and shot the trapped animal. Then he said “It was self defense! They were hunting me!”
