I was hoping he wouldn't show the photos, as (in my thoroughly uninformed opinion) it would only inflame al Qaeda & serve as wonderful recruitment fodder, so the only good reason would be to convince doubters, but it wouldn't even effect that purpose; -- doubters would scoff at photos in this age of photoshop (would have even before it, for that matter) -- would doubt even if the corpse were put into their hands ("It's obviously someone else's dead body with OBL's face grafted on", etc.). 

Speaking of.  On "Happy Endings" last night: an exchange went something like:
Alex: I can't believe you haven't caught that mouse yet.
Dave:  I know! he’s my bin Laden. (pause) Jessica bin Laden, this super-hot Arab girl I went to college with.

The audio on his next line was so obviously erased! - his lips were moving, but there was no sound.  After a few rewinds, I was pretty sure this is what he said, but I knew I had to be wrong, because I'm sure I have no idea why that would be funny.
