I have been asked to come in to talk to a few prosecutors about students that have taken my CCW course over the years. In one case, the prosecutor was seeking to use the course to hold the person to a higher standard than the law required...did not work and I believe my knowledge of the law and figuring out what he was trying to do benefited this past student. In the other cases, it seemed like the Prosecutor was just dotting the "i's" and crossing the "t's" and it was no big deal. Very few instructors have been endorsed as an expert in a legal or civil trial and most would probably be used against their students as opposed to in support of their actions. So I agree with Jim's assessment in post #33.
