A new sanctuary movement is sweeping the country. No, I am not talking about immigration sanctuaries, which have more and less been proliferating since the 1980s. Rather, I am talking about the emergence of Second Amendment sanctuaries, focused on protecting the right to keep and bear arms, and which have been adopted by more than 400 localities in just the past two years. Through a series of resolutions, Second Amendment sanctuaries are expressing their support for gun rights. They are attacking existing and proposed gun control legislation. And more importantly, these sanctuaries are declaring that no governmental resource or personnel will be used to enforce laws that “unconstitutionally” or “unnecessarily” infringe upon the Second Amendment rights of their residents to keep and bear arms.
