I think the guy will get off, looked like self defense to me. His biggest mistake, going out to defend a statue. You don't win wars scuffling with foot soldiers. Stay home, tend your garden unless it is time to take decisive action. Second mistake, if you are going to be dumb and defend a statue you need to do it with a line of similarly intended people who do not break and run in the face of a mob. So, stay home and leave the street battle cosplay to the red army.
