In my opinion the U.S. might as well release the photos of Osama bin Laden's corpse. I have yet to hear a good reason for not doing so. The administration has already revealed all sorts of information about the raid -- before getting its facts straight -- that it should have just kept quiet about. The less details known about such operations the better. We need those units out there killing more enemies, and a high level of secrecy helps. But at the same time I consider the photos a minor issue, not worthy of the frenzy of commentating it has stirred up. People that refuse to believe bin Laden is dead will not be convinced by photos, because they aren't the type of people who are susceptible to facts and evidence. They'll just assume the pictures are fakes.
I have no interest in seeing pictures of Osama dead. But for those who do, since the U.S. is bad at keeping secrets, they'll probably eventually be leaked anyway.
