CBS News: Pakistan has set free a top-level al Qaeda prisoner who spent years guarding and fighting alongside Osama bin Laden, according to two senior Pakistani police officials, who tell CBS News Amin al-Haq was not a "key player" in the terror group, and "had no information of great value". "Eventually there was nothing that could be used to keep holding him in custody," said one of the officials, both of whom spoke to CBS News' Farhan Bokhari on condition of anonymity.
