Even al Qaeda has confirmed that Osama bin Laden was killed by Navy Seals. But Osama bin Laden's son, Omar bin Laden, says he and his family are "not convinced" his father is dead.

In a statement published by the New York Times, Omar bin Laden writes:

I Omar Ossama Binladin and my brothers the lawful children and heirs of the Ossama Binladin (OBL) have noted wide coverage of the news of the death of our father, but we are not convinced on the available evidence in the absence of dead body, photographs, and video evidence that our natural father is dead. Therefore, with this press statement, we seek such conclusive evidence to believe the stories published in relation to 2 May 2011 operation Geronimo as declared by the President of United States Barrack Hussein Obama in his speech that he authorized the said operation and killing of OBL and later confirmed his death.

The family also wants the UN to investigate the legality of the operation that killed an unarmed Osama bin Laden, which they claim "blatantly violated" international law. (International law experts also have some doubts.)

OBL's family will never see the proof that will convince them he's dead. But it's just three short stages from "denial" to "acceptance".
