The standard of proof in Illinois for Self-Defence is not that hard to prove.
His conviction was always a long shot.
The prosecution could have crafted different charges that might have better stuck, but not likely.
There is not a lick of evidence that Rittenhouse was or is a white-supremicist. Stupid white kid, lacking in the training or maturity to be in that situation, definitely.
That is not to say that white privilege and/or that white-supremicists contributed to his defence fund and supported him.
He would have been found guilty in Canada, but then again, he would have never been here in the situation in the first place. Our laws and landscape differ. We just don't act or think as they do.
Par for the course for the shit-hole known as the United States of America.
