Except here's the other thing: religious fanatic terrorists who go undercover often practice disinformation -- they don't talk about religion, they drink alcohol, they shave their beards, etc. -- so people don't know an attack is coming. Hasan could barely contain himself. He posted in favor of suicide bombers online, apparently; he told lots of people he was frantic to avoid deployment to Afghanistan or Iraq. And to cap it all off, he had trouble with women. According to the Washington Post, he'd participated in a Muslim matchmaking service at his mosque, but came up a blank because he had "too many conditions." He refused to be photographed with women, which was awkward when the workplace did group photos.
Current news is that it was when Hasan was taken down, it was a woman who shot him. Four times.
I cannot talk about the incident tactically, because reports are *still* all over the place. My best guess at this point is that Hasan is ideologically motivated and went over the tipping point due to emotional imbalance. Local news reporters are saying he was giving furniture and possessions to neighbors, which is a *classic* suicide thing to do, but you don't see it often in guys who are taking orders from higher-ups. So despite similarities to some busted-up terrorist plans, it's looking for now more like Hasan was a terrorist on his own nickel.
Still wondering about the reported other guy/guys, though.
