The American effort to take out top Al Qaeda figures scored another major victory on Friday when a drone strike killed Anwar Al-Awlaki, the leader of the terror network’s efforts in the Arabian peninsula. How significant is this killing? Will it be a major disruption to terrorist operations or will someone else fill his shoes pretty easily? Was the killing justified or should Al-Awlaki have been arrested because he is an American citizen? And is his role in inspiring the Ft. Hood shooter being minimized for political reasons? We discuss it all with Catherine Herridge, national correspondent for the FOX News Channel.
