Was the Osama Bin Ladin Death Photo Photoshopped?

An interesting comparison of Osama Bin Ladin photos has been released. Take a look and decide for yourself. Has the Osama Bin Ladin death photo Photoshopped?

 It is interesting that if you flip the photo, it is on the same angle. Could this be a publicity stunt to save Obama's poor approval ratings. Interesting the United States government buried Osama at sea where there would be no proof of his body, rather than bring him back as a trophy to verify his death. We are told this is to comply with the customs of Islam, but I get the strange feeling radical Islam was already upset with us before the body was buried.

What do you think?
