I call BS on them having his DNA. There is so much dis-information and lies going out about this guy. He's an ethnic Palestinian born in a refugee camp, he's a Jordanian, he lost his leg, his leg was only damaged, he's on the run...it goes on and on. We've heard he's been killed at least 5 times, I can even remember Al Qaeda in Iraq even asking Muslims to pray for him because he was wounded. First it was Saddam and his sons, and then it was Al Sadr, now Al Zarqawi's America's No.1 target in Iraq. I would question anything from ANY source that comes out about this guy. Now his family has claimed to disown him, a tribe that he was born to when before no one knew where he came from. Who'd even heard of Al Zarqawi before Powell's UN speech? The only evidence he even exists is the occasionaly voice recording (how reliable) and the Nick Berg video, but even there he's masked and doesnt look to have an amputation.
I'm not saying he doesnt exist but both sides are clearly exploiting the Zarqawi legend, and frankly his resume has definatly been padded.
