On Sunday, Jerad and Amanda Miller, a married couple, allegedly killed two police officers in an ambush at a Las Vegas pizza restaurant and then murdered another person in an adjacent Walmart. During the attack, the couple reportedly stated that their attack was part of a "revolution," according to Second Assistant Sheriff Kevin McMahill. The Millers appear to have been motivated by extreme far-right views. The couple left a flag at the scene of the crime with the words "Don't Tread on Me," a Revolutionary War symbol used by some anti-government extremists. They also left a swastika at the scene, though McMahill cautioned to reporters, "We don't necessary believe that they are white supremacists or associated with the Nazi movement. We believe that they equate government and law enforcement ...with Nazis."

McMahill told reporters that he had heard reports that the @placeholder had spoken to a neighbor about their plans adding "You know we have the 'see something, say something' campaign," and urged that, "We need to hear about those times when individuals or groups of individuals are talking about going out and committing acts of violence -- whether it's against the police or anybody else in our community."
