All cities are sanctuary cities. Each city decides unofficially which laws to enforce, which will be few in comparison to the number of laws on the books at the federal, state, and local level. Each city allocates money to enforcing a relative handful of laws and regulations. There is a division of labor with respect to this enforcement. Different cities have different degrees of enforcement. People who live in these communities learn which laws are enforced rigorously, and which are not. People adjust their behavior to their perception of the risks of breaking a particular law.
Modern man lives in terms of what R. J. Rushdoony called the politics of guilt and pity. Ayn Rand made a similar point. There are so many laws on the books, Rand said, that everybody feels guilty about being a lawbreaker. This makes citizens more pliable politically and judicially.All Cities Are Sanctuary Cities
