I think the government has adequate proof that they got the right guy. It would be highly embarrassing if it came out later that they didn't. Why make a press statement at all if they weren't sure?
I personally don't feel a need to see the evidence. I think releasing photos of a body would just throw fuel on the fire of those who hate us, so I don't think making the photos public serves any purpose. Let the evidence be preserved for historians to examine far, far into the future.
