Daniel Perry and Kyle Rittenhouse happened for the simple reason that BLM protests were violent protests.
Danny Boy and Fat Kyle were in two completely opposite situations.
Fat Kyle brought a gun to a protest/riot situation for no reason after being inflamed by online right wing trolls and waved it around before he committed his murders.
Danny Boy shot someone at a protest doing something similar to what Fat Kyle did as described above (self defense?)
By your logic if someone had blown Fat Kyle's head off, they would have been justified in doing so.
Both of them are murderers who are free because their skin color and ideology are correct for the right wing narrative. The "law and order" the GOP once claimed to care about is a dog whistle. Your leader is a felonious, immoral idiot and Abbott is a pathetic seditionist.
