The courts are rather hostile to the right to keep and bear arms. Scalia radically modified precedent when he issued the Heller ruling, and SCOTUS "allows" the Circuit Courts to issue anti-RKBA rulings. For example, the DC Circuit recently held that a ban on 10 round magazines is constitutional. The case was appealed to SCOTUS, SCOTUS declined to hear it. That case is referred to as "Heller II."

This way a person can travel from state to state and the effete elites will just have to get over themselves.
