Which act prohibits using federal troops for law enforcement?

• A. Insurrection Act
• B. Stafford Act
• C. Posse Comitatus Act
• D. DoD 10 Day Authority

Answer: (C)

The main idea is that there is a legal limit on using the military for civilian policing. The Posse Comitatus Act directly addresses this by generally prohibiting active-duty federal troops from enforcing civilian laws inside the United States. It’s designed to keep military power separate from domestic police work and to rely on civilian authorities for law enforcement. There are narrow exceptions and ways around it—such as when the Insurrection Act allows troops to assist under certain conditions or when Congress or the President authorizes action—so the act isn’t an absolute ban, but it sets the baseline restriction. The other options don’t establish that broad prohibition: the Insurrection Act is what lets troops intervene in extreme cases to restore order, the Stafford Act governs federal disaster relief and emergencies, and the so-called DoD 10 Day Authority isn’t the formal statute that prohibits police use of federal troops.
