SEALs are trained to follow orders. If they were told to take him alive, they could have taken him alive. Especially since only one of the hostiles was armed. They were told to bring back a body. From the second that they raided the compound, the death of Bin Laden was the only option. I have little doubt that their mission was to kill. Based on the fact that he said that he ordered the mission, I have to think that the order to kill came from the President of the United States. I can understand why it was done. But its becoming obvious now that the SEAL team was sent in to kill Bin Laden.
Obama should just acknowledge that he ordered the SEAL team to kill Bin Laden due to the dangerous nature of the mission. No one but people who will never vote for him anyway would hold it against him. Most would acknowledge that it was a smart move.
Otherwise, he and his team will continue to dance around it, make little slip ups, continue to contradict themselves as new evidence comes to light, and eventually the truth will come out and it will be an embarrassment not only for the administration but for our country as a whole.
