sanctuary is an alt/right term ... that labels and condemns local police for not accepting the additional FEDERAL responsibility to function as ICE on top of their already overburdened local responsibilities.   Fact.

For those who remember the legal battles across the country when there was an effort to deputize local police departments. They resisted being forced to serve as 'federal agents'. It would forever confuse jurisdiction and legal boundaries.  Now, its lost the alt/right origins.
