Good Question and one that many of us worry about I'm sure. I'm wondering if the NRA, JPOFO, 2nd Amendment Foundation, etc. has a listing of CCW/Pro 2nd Amendment attorneys from city to city. Would be helpful if such a database excisted.
I know of one in Roanoke, VA who is not only a collector and shooter but also one of the best lawyers in the area.
A source might be the instructors at some of the major schools.
