How Did He Hide
Questions remain over who knew about Osama Bin Laden's Pakistan compound linger.
Pakistan is facing growing questions about how the Osama Bin Laden could have lived in a massive suburban compound there for years without its government's knowledge.
"Clearly there's some type of support network that provided him assistance and helped facilitate contact between Bin Laden and his operatives," says White House Counterterrorism Advisor John Brennan.
While the U.S. and Pakistan investigate, the spotlight is also turning to interrogation techniques used by the Bush administration.
Officials say the CIA got the nickname of the courier that eventually led them to Bin Laden from 9/11 mastermind Khalid Sheik Mohammed, who was often waterboarded as part of his questioning.
Still, it wasn't until years later that officials were able to figure out who that courier was.
The White House has released photos of the tense moments as President Obama watched the raid unfold in real time, and is now deciding whether to make public photos of Bin Laden's body and burial.
"The additional release of information or any type of photographic evidence is something we have to take into account in terms of what the reaction might be to it," Brennan says.
In an interview with Time magazine, CIA chief Leon Panetta says they are now mining an "impressive data stash from the compound".
He also says they were only 60 to 80 percent sure Osama Bin Laden was inside, and that including the Pakistani government in the raid would have jeopardized the result.
