State police or highway patrol agencies may assist in investigations and provide support to local agencies.

• A. Federal Agencies
• B. Local Law Enforcement
• C. State Police
• D. International Police

Answer: (C)

State police or highway patrols are the state-level partners that can step in to help local departments with investigations, provide specialized resources, and coordinate efforts across the entire state when local agencies need backup. Their authority spans statewide, making them the natural source of support for local law enforcement facing large cases, complex investigations, or situations requiring additional manpower. Federal agencies operate at the national level and aren’t described as the standard source of statewide local assistance in this context. Local law enforcement refers to the city or county agencies being assisted, not the ones providing the help. International police isn’t a typical domestic option for this kind of state–local cooperation.
