Should governments cooperate with federal immigration enforcement even when local laws restrict it?

Context

The debate over local-federal immigration enforcement cooperation centers on whether state and local governments should assist federal Immigration and Customs Enforcement (ICE) despite local laws that restrict such cooperation. Some jurisdictions have enacted 'sanctuary' policies limiting police involvement in immigration enforcement, citing concerns about community trust and civil liberties, while federal authorities argue cooperation improves public safety and enforcement efficiency. This tension has intensified as ICE has offered financial incentives to local police and some states have moved to restrict or mandate cooperation, creating a fundamental clash between local autonomy and federal immigration authority.
