It was a fitting end for the America's most wanted man. As President Barack Obama's Deputy National Security Adviser John Brennan told it, a cowardly Osama bin Laden used his own wife as a human shield in his final moments. Except that apparently wasn't what happened at all.Hours later, other administration officials were clarifying Brennan's account. Turns out the woman that was killed on the compound wasn't bin Laden's wife. Bin Laden may have not even been using a human shield. And he might not have even been holding a gun.
