Which officer is described as having jurisdiction across state borders?

• A. PO from adjoining states
• B. Sheriff from the county
• C. State Trooper
• D. Federal agent

Answer: (A)

Cross-border enforcement is about extraterritorial authority that lets officers operate beyond their home state under intergovernmental agreements. Officers from adjoining states are specifically described as having this kind of cross-border reach because neighboring states often sign mutual-aid compacts that permit them to assist, pursue suspects, and take enforcement action across state lines when needed. This arrangement relies on coordination and proper authorization, enabling quick cooperation across borders.

In contrast, a sheriff typically has jurisdiction limited to their county within one state, a state trooper operates statewide within their own state, and a federal agent acts under federal authority nationwide but not usually described as extending cross-border enforcement in the same way mutual-aid cross-border arrangements do.
