Osama's Dead?

The Times UK features a story today from Dominic Kennedy claiming that, "A slip of the tongue by one of Osama bin Laden’s top henchmen seems to have betrayed al-Qaeda’s most potent secret: its charismatic leader is dead." "The blunder," writes Kennedy, "was made by Khalid Sheikh Mohammed, who has confessed to being the operational mastermind behind the September 11 attacks. He made his mistake while disclosing many of the secrets behind the atrocities, which were plotted in Kandahar, the religious extremist Taleban movement’s Afghan spiritual home."
