I feel sorry for any federal agents that want to come in here and try to push us around, or anything like that. I really don't want violence toward them, but if they're gonna come bring violence to us, well, if that's the language they want to speak, we'll learn it.This confirms Miller to have been a member of the militia group "defending" Bundy from federal agents; Miller himself states he had been present on his own Facebook page. Miller was also at least active enough in Nevada politics to attend a February Libertarian Party debate between sheriff candidates, where he had his picture taken with prominent Bundy militia member Richard Mack.
Miller's depth of involvement with the Bundy militia after April is less clear, although he requested that someone "send me a rifle" in May, saying "Revolution is coming and we are not prepared! Help," a request that meshes with simultaneous Bundy militia requests for money and other resources in order to "continue" their "defense" of the ranch. While the Bundy clan disavows knowledge of Miller, the news that members of the group might be involved in the executions of law enforcement officers in Las Vegas seemed to come to no great surprise to Mack himself:
Reached this morning by Hatewatch with the news, Mack professed shock. “Oh, no,” he said. “I was afraid that he might have been at the Bundy ranch. As soon as I heard about it, I was afraid of that.”Miller and his wife are said to have draped some object depicting a Gadsden flag, an omnipresent symbol within the Patriot and tea party movements, over the murdered officers.
