“[Obtain] information about criminal aliens in jurisdictions across the United States, particularly those inside ‘sanctuary’ jurisdictions” (General Welfare, Dept. of Justice, Page 567)

Sanctuary cities often refuse requests from federal immigration authorities to detain undocumented immigrants apprehended for low-level offenses. The goal is to foster trust and cooperation between local law enforcement and immigrant communities, allowing immigrants to work with police without fear of deportation. A 2020 study found that sanctuary cities improve public safety and found no evidence of an increase in crime.

This policy would discourage immigrant cooperation with local law enforcement, likely leading to an increase in crime in those communities. For more information about sanctuary policies, see this fact sheet.
