As America entered WWI, Congress passed a law making it illegal to speak out against the war or fail to register for the draft. These two laws led to the deadliest shootout in Arizona’s history as a family of silver prospectors silently protested America’s entry into the war. The Feds’ midnight attack on the sleeping men eerily presages today’s no-knock SWAT raids. Narrated by “Mad Men” star John Slattery and featuring interviews with lead historians Eduardo Pagan (PBS History Detectives), Heidi Osselaer (ASU), Marshall Trimble, and author Thomas Cobb (Crazy Heart), this documentary tells the story of the war that pitted the rights of individuals against the growing power of the federal government.
