That's the problem. They are going to have to release pictures eventually. When Saddam was killed his picture was splashed across the front page of the NY Post the next day. OBL was THE big catch. Why not show us and gloat some more? Rather than bomb the compound, they went to all the trouble of personally killing him only to give him a "proper" muslim burial and toss him in the ocean? Makes no sense to me.
Even after bombing the compound we would have to send in men to scrape the DNA off the walls. I wouldn't say that the "proper" burial had anything to do with the say they went in, they went in correctly and did everything correctly. After that it was political correctness and that includes the "no pictures" commandment (so far anyway).
