Besides experience in the art, what kind of experience do you look for in a martial arts instructor? For example, I tend to like to train with people who have actual hands on experience with putting the principles in action. People who have served in combat, people who have experience with body guarding, people with LEO experience, experienced bouncers and/or security professionals. Beyond the art itself, these type of people seem to have the kind of personal experience that helps with real life application.
