Good letter. Maybe include some quotes from victims who "never thought it would happen to me". I would guess this judge would like to see you get mugged once or twice so that you have a "good reason" to carry. I wonder if the state could be sued if you are still denied the permit, and then are mugged (or something along those lines). It would seem they would be responsible for the fact you were not able to defend yourself. Any lawyers know if that's a possibility?
