Sanctuary cities are municipalities that adopt policies to limit cooperation with federal immigration enforcement. These cities often prioritize local resources for community safety and welfare rather than immigration status. This means that local law enforcement may not inquire about a person's immigration status or may not detain individuals solely based on immigration violations. Supporters argue that sanctuary cities promote trust between immigrant communities and local law enforcement, encouraging individuals to report crimes without fear of deportation. Critics, however, claim that these policies can undermine federal immigration laws and may lead to increased crime. The debate continues over the effectiveness and implications of sanctuary city policies.
