Zimmerman and Rittenhouse were found innocent because they killed both a black guy and white people protesting for the rights of black people.
That's all you need to know really.
Edited for clarity: Since reading comprehension seems to be a lost art. Zimmernman killed a black guy, Rittenhouse killed whites protesting for black rights
I am not saying Rittenhouse killed anyone who was black.
Tell me again: What black guy did Rittenhouse kill?
I know about Joseph Rosenbaum, a white guy who attacked him and grabbed his gun when Rittenhouse didn't run away fast enough. That attack was on camera.
I know about Anthony Huber, a white guy who was killed with a single shot to the chest while trying to hit him in the head with the trucks of a skateboard. That attack was also on camera.
I know about Gaige Grosskreutz, a white guy who tried to shoot at Rittenhouse, then feigned surrender, then suddenly pointed his gun again and tried to kill him, before being struck in the arm by rifle fire. That attack was also on camera.
And I know about the unidentified black man who tried to stomp on Rittenhouse's head while he was on the ground, who Rittenhouse fired on once, but missed, and did not fire again as the man decided to flee rather than continue the attack.
But I don't seem to recall the name of the black man that you're referring to: The black man that Rittenhouse supposedly killed. I know he was the third dead guy on the night that Rittenhouse killed two people, but I can't seem to recall his name.
