First the lies, then the explanation of the lies

"Bin Laden’s wife, who was with him in the room, “rushed the U.S. assaulter and was shot in the leg but not killed,” said the White House spokesman, Jay Carney, reading from the brief account, which was provided by the Defense Department. “Bin Laden was then shot and killed. He was not armed.”  Mr. Carney said that Bin Laden’s lack of a weapon did not mean he was ready to surrender, and he and other officials reiterated that this was a violent scene, that there was heavy fire from others in the house, and that the commandos did not know whether the occupants were wearing suicide belts or other explosives.   Still, the account diverged in some ways from one given Monday by the president’s chief counterterrorism adviser, John O. Brennan. He had said Bin Laden was “engaged in a firefight with those that entered the area of the house he was in,” adding, “whether or not he got off any rounds, I frankly don’t know.”  Mr. Brennan also said then that Bin Laden used his wife as a “human shield.” But officials now say that the death of another woman in the crossfire on another floor led them to draw that false conclusion.  White House officials said the discrepancies resulted from their haste to provide details about a chaotic, fast-moving military operation to an intensely interested American public. As more of the assault team’s 79 members were debriefed, and their accounts were crosschecked with those of other team members, there were bound to be changes in the account, these officials said."
