I also a MMA fighter and a 5th degree black belt. I run to schools and train fighters.
Where I live I have to be careful about the type of force I use with my hands and feet. Because of the fact that I am a pro fighter would give the other guy more of a stance to sue me. So I am carefull about the situations I hope to never get into.....
With that being said. You know he is a tuff guy with the abbiliy to realy harm or even kill you if u were to get into a fight. So you may end up fearing for ur life in that said fight. Tread lightly laws are funny in the way they work for the attacker and not the victim
