Justice served - yeah, maybe. I'm not in possession of all the details of the case, so I can't say for sure. I'll certainly go along with it. I'm not sure Joe Biden believes the guilty verdict was justice, though.

Biden says he wants to usher reform that will mean black and brown people won't get killed by cops. Well, I've got a very simple solution. US citizens: comply with officers of the law. <--- not difficult, is it?
Biden also mentions systemic racism in the US criminal and justice system. Chauvin was fired and arrested immediately after killing Floyd, and was recently found guilty on all counts. I'm not sure systemic racism even exists in American institutions.
