Sanctuary city

A sanctuary city is a municipal area that limits cooperation with the government's effort to enforce immigration law. They are mainly in Western Europe, the United States and Canada.
Leaders of sanctuary cities say they wish to cut down fear of deportation and possible family breakups with people who are in a country illegally. That's so that such people may be willing to report a crime and send their children to school.
Some states, such as Alabama, Iowa, Mississippi, Georgia, Missouri and Florida do not allow sanctuary cities. Others, such as Connecticut, Rhode Island, Illinois New York, Colorado and California allow sanctuary cities.
In early 2018, a Chicago federal judge said that the Trump administration could "not" withhold public safety grants to sancutary cities. Those decisions were seen as a setback to the Trump administration efforts for helping authorities police illegal immigrants.
