How can Obama expect anyone to believe bin Laden is really dead without any evidence whatsoever?

I am not a conspiracy theorist. I am a rational, freethinking, open-minded individual who strongly believes that extraordinary claims require extraordinary evidence. Of course, I know there are a number of brainwashed American (pardon me) "sheep" out there who may criticize this question, saying that the White House would have nothing to gain from lying about such things. This is a straw-man argument if I ever heard one. What about the birth certificate issue? (I do realize this is in and of itself a very separate issue, but still.) Even if there were no reasons whatsoever, why is it not perfectly appropriate to ask for photographic proof? I do find the story quite suspicious. The most wanted man in the world is finally found, killed, conveniently buried at sea, and given more respect than 90% of the American victims of Al Qaeda and third-part terrorism combined. Not a whole lot of justice going on here, if you ask me.
