It is a state law as it was codified under pre-emption. That makes it a violation of the US Constitution under equal protection in that the citizens of Clark County have been singled out to have fewer rights than the citizens of the rest of the state by our State Legislature. I think this would be the perfect case for the NRA to pick up and take to court on our behalf. Anone who has had to register would be a qualified litigant. I'm thinking it would be much easier to win this way than fighting it though the legislature. Just my opinion.
