(h) Unless presented with a federal criminal warrant, or otherwise required by federal law, a law enforcement agency or official may not:

(1) participate, support, or assist in any capacity with an immigration agent's enforcement operations, including any collateral assistance such as coordinating an arrest in a courthouse or other public facility, providing use of any equipment, transporting any individuals, or establishing a security or traffic perimeter surrounding such operations, or any other on-site support;

(6) provide information in response to any immigration agent's inquiry or request for information regarding any individual in the agency's custody; or
