Should local governments be able to limit federal immigration enforcement within their cities?

Context

The question of whether local governments can limit federal immigration enforcement within their jurisdictions sits at the intersection of federalism, public safety, and immigration policy. Some cities and states argue that restricting local police cooperation with federal immigration authorities protects vulnerable communities and allows officers to focus on local crime; others contend that such limits undermine federal immigration law and create inconsistent enforcement. This debate has intensified as sanctuary policies spread across major cities and states, forcing a reckoning over who controls immigration enforcement and what obligations local authorities have to federal agencies.
