The evil twin has a story from Virginia about an open carry arrest in Norfolk (open carry is legal in Virginia). My advice to folks who choose the route of challenging local authorities on state preemption matters such as this is to retain an attorney, and make sure your spouse understands exactly what she needs to do if you get pinched, and is prepared to do it. After being arrested isn’t the time to go find a lawyer.
VCDL is going a good job here though, and I wish them well in their lawsuit against the City of Norfolk on this matter.
