“Sanctuary city”, Wikipedia tells us, “refers to municipal jurisdictions, typically in North America, that limit their cooperation with the national government’s effort to enforce immigration law.” This is not an unreasonable definition. The term sanctuary city first came into modern political and legal parlance in the United States in the 1980s when a handful of cities sought to resist federal government efforts to deport asylum seekers fleeing their violence-wracked Central American homes, and then came to be more generally used to describe a range of local refusals to cooperate with the enforcement of federal immigration law with respect to the detention and removal of undocumented aliens. The association of “sanctuary city” with progressive local jurisdictions resisting federal removal of undocumented aliens remains. The top ten hits for “sanctuary city” on Google after Wikipedia all deal with local resistance to federal immigration law enforcement: The first hit after Wikipedia is the sanctuary city webpage run by the Center for Immigration Studies, an anti-sanctuary organization.
Sanctuary city has long been a bit of a misnomer. As the CIS webpage notes there are sanctuary counties (approximately 130) and sanctuary states (eleven), as well as cities, but until recently the association of sanctuary with progressive resistance to federal (and federally-supportive state) policies has been strong. No longer. Starting around 2013, and spreading rapidly from 2018, a host of counties and cities have declared themselves to be “Second Amendment sanctuaries.” By one count there are over 950 Second Amendment sanctuary counties (roughly 25% of all US counties) and nearly 200 Second Amendment sanctuary cities, towns, or townships. Although the meaning of “Second Amendment sanctuary” is even more indeterminate than alien sanctuary – ranging from expressions of opposition to various firearms regulations, to assertions of refusal to enforce by local authorities, to commitments to provide financial support to local resistance – the rapid spread and scope of the movement is impressive.
