An ex police officer Christopher Dorner has already killed 3 people, and severely wounded one. He's being hunted by L.A.P.D. He has been fired for falsely accusing another officer of using excessive force in 2008, and seems to be after revenge. "The violence of action will be high. I will bring unconventional and asymmetrical warfare to those in LAPD uniform whether on or off duty," Dorner wrote. "The attacks will stop when the department states the truth about my innocence."
