CNN has been doing research into what cop killer Christopher Dorner has with him. He does have both military and police training and has already slain three people during his rampage. With the manhunt heating up and now drones being used to search for him, the news network took a closer look at what weapons he has with him. He claims to have a .50 Cal with him, evidenced by his destruction of an LAPD vehicle during a shootout. But even more distressing is that he claims to have a surface to air missile with him. [Video]
