Yesterday we learned that Justin Bieber is a suspect in a criminal battery case after an altercation with a photographer. It sounds like the photographer may just be trying to get a few bucks out of Bieber, but this video shows that if things do turn physical, the young pop star is ready. We've seen him in the ring before, but check him out training with Mike Tyson.
