Was al Qaeda or ISIS behind the attack on Charlie Hebdo?

Former Deputy and Acting Director of the CIA Mike Morell called the attack on Charlie Hebdo, "sophisticated." In reference to images of a bullet ridden windshield, Morell said the alignment of the holes shows that the individuals must have had some sort of military training.

"CBS Evening News" anchor Scott Pelley asked Morell if there's any indication as to who may be behind the attack. Morell answered by saying no group has been identified but that there's reason to believe al Qaeda is a more likely culprit than ISIS.
