What is the primary mission of the U.S. Marshals Service?

• A. Enforce state laws and regulate local courts.
• B. Protect the federal judiciary and court system, enforce federal laws, apprehend fugitives, transport and guard federal prisoners, and provide witness protection and courthouse security.
• C. Operate federal prisons and manage federal surveillance.
• D. Provide civilian law enforcement across the entire United States.

Answer: (B)

The main idea is that the U.S. Marshals Service exists to safeguard the federal judiciary and the court system while carrying out related enforcement duties. This includes enforcing federal laws, apprehending fugitives, transporting and guarding federal prisoners, and providing witness protection and courthouse security. This combination is what defines their work and separates them from agencies that handle state or local policing, prison administration, or broader nationwide enforcement.
