Along with BeerNuts's post, stmadeveloper made some solid points here and here.
Note that some of us are not saying, "POTUS IS LYING. OSAMA IS ALIVE. OSAMA WAS KILLED IN 2003!"
We're saying (to the administration), "Yeah, we heard you. But you guys have lied to us so many times, we'd be pretty stupid to believe things at face value. You say OBL got dead in a certain way at a certain time? Fine. I can't trust you to tell the truth, but... fine."
Not only that, but their reasoning makes no sense at all. They don't want to produce propaganda, and yet leave bodies in the compound? And if they weren't going to take and release photos, then why risk Navy seals to go in at all? Why not just bomb the place and scrape DNA off of the rubble?
I never gave 2 shits about a birth-certificate, but this is straight up BS.
