According to Colorado’s state constitution, an individual’s right “to keep and bear arms in defense of his home, person and property” shall not “be called in question.”

But now that Colorado has become the first state in the nation to repeal its firearm preemption law, that right is very much in question. Forty-four states have a preemption law — a law that prevents cities and towns from regulating firearms more restrictively than the state as a whole.
