There have been successful campaigns in getting other parts of the local governments to adhere to the law. DMVs and other public buildings/property now properly allow open carry after letter writing and other forms of political action. However, Las Vegas Metro PD never got on board.
Well heaven help us if we try to get law enforcement to understand that laws apply to them too.
The basic Nevada law on gov't buildings is a good one: if the building in question wants to disarm you, they have to do metal detectors, guards and lockers. This limits building disarmament to only those buildings where there's a real risk, AND prevents them from forcing you to mix with criminals who are packing and who declined to voluntarily check a weapon or leave it in the car.
