Maybe I am way off base, but how many people "have an attorney". I have never used one and the moments after a SD shooting would not be the best time to be thumbing through the yellow pages
You're not off-base at all. This was a strong recommendation for something to consider from different instructors I've had, for just the reason you mentioned.
I do have one, did not always. It was not as easy to find one as you might think. You also need to find someone you feel comfortable with, for many reasons.
