Did Hasan Act Alone?

Two days after Major Nidal Malik Hasan allegedly opened fire on soldiers at Fort Hood, numerous questions remain as to his motive and planning, beginning with whether or not he acted alone. Senator Kay Bailey Hutchison (R-TX) told The New York Times that Army officials are investigating “if there is something more than just one deranged person involved here," while officials have so far not publicly ruled out whether Hasan may have been connected to outside persons or groups in orchestrating his attack. A law-enforcement official told the Times that so far searches of Hasan's computer have turned up no direct exchanges with known terrorists. Hasan, who survived the attack and is in custody, is reportedly comatose and has yet to be questioned.
