Drawing on deep access to key people on all sides of the battle, Frontline: American Patriot (PBS Distribution) investigates the standoffs that propelled the Bundy family into the national spotlight and the crosshairs of the federal government. With “Patriot” groups that rallied to the Bundys’ cause surging to levels not seen in decades, the film also reports on what’s next for the family and the wider movement around them. The riveting documentary will be available on DVD June 13; the program will also be available for digital download.

The effort traces the Bundy family’s story as ranchers in the high deserts of Nevada, grazing cattle for generations on federal land and ultimately going to war against the government.

Now, their fight has become a lot bigger.

What began as one family’s dispute with the government over grazing fees has reinvigorated a national movement of self-styled militias and “Patriots.” They believe the federal government has overstepped its authority, strayed from its founding principles, and is filled with agents they are duty-bound to oppose. They call themselves Oath Keepers, Constitutional Sheriffs, sovereign citizens, Three Percenters. And while each group has its own cause, they rally under the same banner: opposition to federal overreach.

Over the past several years, many of these “Patriots” have answered the Bundys’ call, taking up arms to defend against what they see as government infringement of their rights as American citizens. In 2014, armed men faced down the federal government at the Bundy ranch when agents came to impound their cattle. In the end, the federal agents backed down. Then, last year, armed “Patriots” again joined Ammon and Ryan when they occupied a federal wildlife preserve in Oregon to protest the imprisonment of fellow ranchers, the Hammonds, who were convicted of starting fires on federal lands. Last October, Ammon, Ryan and five other supporters were acquitted of federal charges relating to the occupation. A trial for the remaining defendants is scheduled to begin next month.

 American Patriot and the accompanying written and audio story helps audiences to understand the Bundys, their fight and the people who have rallied to their cause.
