Sufyan bin Qumu was released from Guantanamo in 2007 to the Libyan regime headed by Muammar Qaddafi. Qaddafi jailed him, but he was then set free on a promise to renounce violence. When the Arab Spring uprising began in Libya, Qumu became part of the rebel movement which eventually toppled Qaddafi. “He’s a great suspect on paper,” Miller said. “There is some intel about him but it’s way too early to verify these reports we’ve seen that he is the prime suspect or the prime mover. Way too early.” CBS News correspondent Margaret Brennan reports FBI investigators in Libya haven’t yet gone to the destroyed consulate, and Miller cautions it’s still too soon to make any firm determinations about the attack. “Whether it was pre-planned or not is tough because in this environment, in Libya,” says Miller. “In a normal place when people show up with weapons and cars and an effective assault, you say that requires pre-operational planning. Libya’s a place that went through 13 months of this. There’s all kinds of weapons and militias with cars and weapons, so it’s the one kind of place this could happen spontaneously.”
