And being guilty is not the same thing as being proven guilty. There are lots of things that are true which haven't been proven. For example Einstein's theory of relativity before the 20th century. It's certainly wrong to believe that Trump is guilty of a crime simply because you feel that he is a despicable human being. And it's wrong to lynch Trump if he is acquitted, even if he is guilty. It's a principle of Law that one must be not only guilty, but found guilty of a crime in court, before they can be punished for it. But there are excellent reasons for thinking that Trump is guilty, which have nothing to do with anyone's feelings. Anyone who believes based on such reasons is justified in doing so.
