Saddam Hussein died in march 2003 in the first bombings at the start of the Iraq war as reported at the time  http://www.foxnews.com/story/0,2933,81847,00.html
But this has conveniently been forgotten. The man who was "captured" by american forces is one of Saddams many look-alike stand-ins (he had about 20) he is a cousin that is why the DNA test was close enough. If you compare photos there are differences and also why has he not shaved his beard? He disappeared from public view soon after capture and was brainwashed into thinking he was Saddam by the CIA
