Local police are never supposed to deal with immigration issues anyways, it isn't in their jurisdiction and they would have to call feds in to deal with anything related to it.

Generally, a city is called a sanctuary city if they don't honor hold orders on detainees from customs and immigration, it has nothing to do with police not enforcing immigration rules, which they can't do either way.

Right. Plus local police don't have jurisdiction over immigration issues. My comment was more a reflection on how the gov generally is, sadly (and horrifically in Minneapolis etc), much more responsive to undocumented cases than actual crimes.
