This is true. One of the many reasons courts exist is to avoid mob rule. Petitions can't overturn court decisions. They can probably prompt a review, but I don't think that's very likely in this case (in the near future anyway).

My personal opinion is that he tried to make money off of illegal shit, so he should deal with the consequences. That being said, the consequences seem to be overkill in this case. It should definitely get another look.
