According to this, Obama had DNA confirmation that he was dead prior to announcing.

Either way, no body is needed, just a tissue sample.
I love how the right wingers are now taking credit for what happened two years later because of what Bush/Cheney supposedly did 10 years earlier (even though Cheney does not know for a fact that he did anything) but when someone on the left wing says that things done by Bush are relevant to what is going on now in regards to everything else that is going on, that some how is not true. How exactly does that work?
Bush closed the CIA unit tasked for hunting down Bin Ladin in 2005 (even though Bush pledged to hunt down Bin Ladin no mater how long it took) and as early as the first part of 2002 he said that he was not concerned about where or if OBL was hiding.
According to the current reports, when Obama walked in the door, he told the spooks to find the SOB and they did. Did Bush/Cheney have something to do with it? Yes they did. Just as they had something to do with the financial cluster screw up we are in now. It's not like there is a reset button when the new POTUS walks in the door.
