Immigrant communities face unequal access to services due to fear of interactions with local law enforcement that cooperate with federal immigration enforcement, causing distrust among the community, underreporting of crimes, and increased exploitation. Sanctuary policies limit local involvement in immigration enforcement-such as refusing ICE detainers without warrants and restricting data sharing-while promoting safety, inclusion, and legal compliance without increasing crime.
