No big deal here. AG's opinion in 2006 (see letter @ "official letters" @ http://www.vcdl.org ) said the same thing.
VCDL has gotten bills entered in the General Assembly to make preemption total by clarifying that state entities such as Boards of Governors can only make rules regarding firearms as specifically permitted by the General Assembly. Unfortunately, the bills have not been sucessfully voted on -- yet!
As the saying goes - wait till next year.
