I never joined the voices claiming Osama bin Laden was already dead. I also though never joined the voices saying it was a sure thing that he was "the mastermind of the most devastating attack on American soil in modern times." I did report that the FBI never had him on its Most Wanted list for 9/11 because the FBI said it didn't have enough evidence for that.
There is just way too much surrounding the 9/11 events that suggests that even if bin Laden was involved, there was US "official" involvement facilitating the "attacks." Building 7 did not, I repeat, did not come down due to the planes hitting the twin towers. 9/11 still needs investigating regardless of claims of Osama bin Laden's assassination.
Barack Obama had someone Obama believes, reportedly based upon "facial recognition techniques," to be Osama bin Laden killed by US military/CIA forces in Pakistan. The DNA of the body is being analyzed to determine whether it is that of Osama bin Laden.
He was not brought to trial. The news so far doesn't explain why he was not captured alive. I suppose that question will be asked and answered. Whether or not the answer will be sufficient will be another matter.
It brings to mind how George W. Bush captured Saddam Hussein and then tried him in a kangaroo court before pulling off his head, literally. Saddam was tried the way he was so he couldn't speak about US complicity in most of Saddam's dealings.
If Obama had brought Osama to trial in a court not a kangaroo court, Osama would not have been found guilty of 9/11 because there would not have been sufficient evidence for that I more than suspect. Also, many questions would have been raised about who was actually involved.
What I also find offensive, even though Osama bin Laden was far from innocent, is that Americans and others around the world actually cheered and celebrated and were publicly singing and such over bin Laden's killing. What a crass world.
