What must Coast Guard Operational Commanders do when exercising customs authority?

When Coast Guard Operational Commanders exercise customs authority, it is essential that they coordinate activities with local Immigration and Customs Enforcement (ICE) supervisors. This coordination ensures that enforcement actions are consistent with existing federal laws and regulations and promotes effective collaboration among different agencies involved in customs enforcement. Engaging with ICE supervisors allows for the sharing of critical information and resources, optimizing the response and operational efficiencies in customs operations.

Additionally, this collaboration helps maintain a unified approach to law enforcement that respects the roles and jurisdictions of both the Coast Guard and ICE, ultimately enhancing the effectiveness of their enforcement efforts. By working together, they can address potential issues more comprehensively and provide better service to the public.

The other options suggest a lack of necessary collaboration or adherence to established protocols and hierarchy, which would not reflect best practices in law enforcement and customs operations. The emphasis on coordination illustrates the importance of collaboration in executing authority responsibly and effectively.
