I think that you hit it on the head. The courts view us martial artists as experts when it comes to physical aggression. We do have to prove that our aggression was done to defend ourselves, and then we have to illustrate why that situation caused us to act the way that we did.
For example: Why, if you are a black belt in a martial art that focuses on having to defend yourself against 8 attackers..why was it necessary to break my clients (one attackers) wrist with this technique?"
Oh, now lets not forget that after you go through that criminal proceeding ifyou are charged..which I think i should go into first.
Lets say that you are on a scene where you broke a persons nose...thats malicious wounding in virginia, where I am. The Police arrive (myself) and the code states that we have to make an arrest. Yes, you, the caring martial artist gets to take a ride on a malicious wounding charge. Those officers onthe scene are not the "court of Law"..they don't have to be reasoned with..they have a job to do.
Then you go to court...both criminal and civil. Now after you attempt to defend yourself to a judge and jury (time consuming and expensive) in criminal court..now you have to go and do the same damn thing in civil court. Just because you won your criminal case doesn't mean you won't be held liable for his or her damages in the CIVIL world..which requires a different set of criteria to be met.
This is kind of long...LESSON..DON'T PUT YOURSELF IN A SITUATION WHERE YOU HAVE TO FIGHT. That is such an easy thing to do.
Now, we all want to try this stuff that we learn..that we spend so much time practicing, but on the streets, now a days is not the place to do it unless it is absolutely necessary.
