It's the lunatic who blew away two Las Vegas cops as they ate lunch.
Jerad Miller is in full makeup as The Joker in the creepy video was made in 2012. It's an uncanny imitation of Heath Ledger's Oscar-winning role from 2008's The Dark Knight.
In the video, Miller states, "We have a chance to make history ladies and gentlemen." "I'll be able to terrorize the entire nation and possibly, the entire globe. Think of it, a one world order."
In the movie, Heath Ledger's Joker promises chaos.
In his video, Jerad Miller spouts conspiracy theories about concentration camps in the U.S. and the government taking guns from citizens.
"This U.N. gun treaty would take away all your guns," he said in the video.
HLN's Nancy Grace told INSIDE EDITION, "I don't think he was crazy. Not at all. He knew what he was doing. He was a right wing anti-government freak."
Miller said in the video, "I want to be the war monger, not just some every day terrorist, domestic terrorist. I want to blow (blank) up. I want to blow up the whole country, the whole nation. I want to make everybody submit to the one world order governance under my rule!"
On his YouTube channel, Miller also posted videos where he's the polar opposite and speaks of peace and love.
"For those who don't know me, I am a very moral person. I hate evil. I love goodness. I love good people," he said in one video.
Miller and his wife, Amanda videotaped themselves in January as they drove from from Indiana to start a new life for themselves in Las Vegas.
On her Facebook page, Amanda Miller seemed as troubled and disturbed as her husband. In one photo she poses with books on Satanism. And how's this for Christmas presents—books titled The Shooter's Bible and Extreme Survival.
Amanda Miller's father is coming forward claiming she was brainwashed by her husband. "He was just nuts," he said about Miller.
Her family begged her not to marry Miller, but she did anyway.
A vigil was held Monday night outside the pizzeria where the police officers lost their lives.
