There is no "100% closure," moron. As for the rest of your stupid argument, did not the actual killing sufficiently illustrate the point?
Wouldn't it more narcissistic to parade the photos in front of anyone who would pay attention? When the bad guys parade their kill for all the world to see, are they exercising humility? Try to get your own narrative straight.
Since the Pentagon said OBL is dead, why are the people who have more trust in the Pentagon not satisfied? (AK Forty Seven's subsequent remark notwithstanding.)
