I think that most critics of Kyle Rittenhouse don't disagree with the carriage of justice as much as the disgusting capitalization of his person after the fact. And the entire rationalization for bringing a weapon to a protest is frankly sick, whether he used justified force or not.

Naw can't watch the trial, then you'd find out that Rosenbaum had an encounter earlier in the night at a gas station with a guy dressed like Kyle (but +plate carrier) who put out Rosenbaum's dumpster fire (the infanous "Shoot me n-word" video where Rosenbaum gets a pass to say "it.") Then a little while later the drone video where Rosenbaum, still starting fires, crouches behind a car while Kyle walks past, steps out supposedly saying he was going to kill Kyle, and chases him/throws the bag, corners him, someone fires a shot from the crowd (likely Ziminski) while Kyle gets trapped by cars, and turning around hearing a shot Rosenbaum grabs for the gun, so Kyle shoots him. Then he makes the phone call (IIRC to Dominick Black), hears "GET HIM" and he starts running, gets hit in the back of the head with a rock that takes him down, he rolls over as jump kick man gets a hit, points it but doesn't fire as dude was already retreating, Huber hits him with the skateboard and attempts again to take his rifle, shoots Huber, and the other guy who just surrenders, then Gage's fake surrender (war crimes much?) then Gage takes one in the bicep, then Kyle gets up and continues running towards police.

You'd also find out that not only was all that justified, he never "crossed state lines with the gun" as the gun lived in Kenosha at Dominick's house, and he could in fact legally possess the rifle at 17 due to local laws. Furthermore he worked in Kenosha and his dad lived there. While he did travel from his mom's in Antioch 20mi away, Huber came from Silver Lake also 20mi away, and Gage came from 46mi away.

That wouldn't be good, can't learn the actual facts of the case, just gotta hang your hat on "he shouldn't have been there."
