Obama must probe Bush, others over CIA torture, rights group says

US President Barack Obama must investigate his predecessor George W. Bush and allies over the CIA's torture of terror suspects, or stand complicit in a government "cover-up," Human Rights Watch said Tuesday. In a scathing report, the international rights group decried the lack of prosecutions of those involved in the Central Intelligence Agency's secret program to torture detainees in the wake of the September 11, 2001 attacks.
