Stop Dangerous Sanctuary Cities Act

Enhanced Law Enforcement Cooperation: The bill allows State and local law enforcement to act as agents of the Department of Homeland Security when complying with detainers, providing them with all available authority of the Department (Section 2(a)).

Legal Protection for Local Officers: Local officers who comply with Department of Homeland Security detainers are deemed to be acting within the scope of their employment as federal employees, which protects them in legal proceedings (Section 2(b)).

Legal Protection for Local Governments: The act states that no liability shall lie against a State or political subdivision for actions taken in compliance with a federal detainer (Section 2(b)(1)).

Protection for Crime Victims and Witnesses: Jurisdictions are not deemed "sanctuary jurisdictions" if their policies prevent sharing information specifically regarding individuals who come forward as a victim or a witness to a criminal offense (Section 3(b)).

Loss of Federal Funding for Communities: Jurisdictions deemed "sanctuary jurisdictions" become ineligible for Economic Development Administration grants and Community Development Block Grants (Section 4(a) and Section 4(b)).

Mandatory Return of Grant Funds: If a State or local government is determined to be a sanctuary jurisdiction while receiving funds under Title I of the Housing and Community Development Act, they may be required to immediately return those amounts to the Secretary (Section 4(b)(2)(A)).

Redistribution of Funds Away from Certain Areas: Funds returned by sanctuary jurisdictions are reallocated to States and local governments that are not sanctuary jurisdictions (Section 4(b)(2)(A) and Section 4(b)(2)(B)).
