Should sanctuary city policies that limit cooperation with federal immigration enforcement be allowed?

Context

Sanctuary city policies restrict local law enforcement from cooperating with federal immigration authorities, reflecting a tension between local autonomy and federal immigration enforcement. Supporters argue these policies protect vulnerable immigrant communities and allow police to focus on public safety; opponents contend they undermine federal law and create security risks. The debate has intensified as Republican-controlled Congress increasingly scrutinizes sanctuary jurisdictions, while Democratic-led cities like New York and Denver defend or expand such protections.
