I find it very suspect that the Pakistanis would rush to such a conclusion so quickly. I've never believed that the Pakistani government has been completely with us in the War on Terror. Their intelligence services are supposed to be one of the best in the world, and you want me to believe they haven't been able to locate Bin Laden and/or Zawahiri since Tora Bora? No way, I don't buy it, I'll bet they have a very good idea where those two scumbags are probably every day of the week.
I understand the bodies of five of the deceased were quickly taken back to Afghanistan. If they were not Al Qaeda, what's the rush? And if they were Al Qaeda, wouldn't their colleagues want verification of their deaths, and to prevent their remains from falling into CIA hands?
