Initially, also I found that strange. But remember that to many people he's some sort of Jesus figure and a grave on land would attract them like flies are attracted to horse shit. We don't need that to happen.
Who gives a shit if he was to have a shrine in his honour? They could have buried him in a booby-trapped grave, when there's enough of his admirer's standing over it BOOM! My guess is they just didn't want anyone digging the body up to do DNA tests themselves. The general feeling/acceptance around that part of the world is that he died in 2001, if you've been watching their news channels you would hear them saying this story is a load of bull. They're not denying he's dead, just denying that he died recently.
Loving how the story keeps changing, that's why you should concentrate on what is said on the news when it's breaking. Once the 'official' story comes out the media latch onto it and hope you forget about what you heard in the first few hours. Like 9/11, do you remember the reports that vans packed with explosives had been stopped by police and a group of Israelis arrested? The Israelis then getting released and going on TV and saying they were there to document the event? The firefighters, police and numerous other credible witnesses saying bombs were going off in the basement that hadn't even been hit by a plane yet? The people who were trapped in Building 7 after a bomb went off and trapped them in there for hours? People saying cars were exploding in the street? You didn't hear these eyewitness accounts on the news again after the 'official' story started getting reported.
Bin Laden used a woman as a human shield? Now they say he didn't. Bin Laden fired at the SEAL team? Now they say he didn't. The order was to kill not capture? Now they say it was kill or capture. They knew for certain Bin Laden was in the house? Now they say they had to ask his wife when they got there. Hilary Clinton saying the Pakistanis co-operarated with them in the operation? Now they say the Pakistani's knew nothing of it. A Pakistani official saying it was a joint operation? Now the Paki's are fuming that they weren't told about it. Bin Laden was killed last week and the body was back in the US? It goes on.
The first few hours of reporting is where you're likely to hear how things actually went down, some of it might be confusion but it often makes more sense than the bullshit that becomes the official story later on.
Just sayin'
