I have been asking the Right to define, "sanctuary city", for over two years, now, and have never had an answer. For example, South Tucson has declared itself a sanctuary city simply because the feds have refused to reimburse the city for the cost of detaining and incarcerating suspected undocumented immigrants, since they do not feel that it is right for the city to tax their resident citizens to enforce federal law. Since their citizens are already paying federal taxes for that purpose, they would be taxing their citizens twice.
