There is a trial going on for that. Your post is just another of a string of browbeating people because you can't convince them that what they say was not murder. People can form opinions without applying legal standards. For example, Rittenhouse acted guilty as all hell the night he shot three people. Didn't offer aid, didn't turn himself in to the police, he just ran like he was a guilty of murder. He sure seems guilty to me, be that's my opinion. It is based upon facts but nobody is going to have their liberty deprived because of my opinion.
Did he in fact commit murder and will he get punished for it? That's what the trial is for.
