Kevin Drum has a powerful letter from someone who witnessed the carnage at Fort Hood:
This was premeditated. This wasn't VBC again. That guy snapped, not this one. He was so damn calm when he was shooting. Methodical. And he was moving tactically. The Army really is diverse and we really do love all our own. We signed up to be shot at but not at home. Not unarmed. No one should ever see what the inside of that medical SRP building looked like. I suppose that's what VA Tech looked like. Except they didn't have soldiers coming from everywhere to tourniquet and compress and talk to the wounded while rounds are still coming out.
No one touched him...the shooter that is...other than to treat him. Though I told the medic (and I'm not proud of this) that was giving him plasma that there better not be anyone else who needed it because he should be the last one to be treated. But I had just finished holding a soldier who was critical (I counted three entry wounds) and talking to him about his children.... If the shooter had a grievance he should have taken it out on those responsible; he wasn't shooting people he knew (media reports to the contrary). He was just shooting anybody who happened to be present for SRP medical processing, mainly lower enlisted.
But please, no one use this politically! The Army is not "broken", PTSD doesn't turn people into killers, most Muslims aren't evil, and whether we should stay or go in Afghanistan has nothing to do with this. I'm babbling...sorry.
This guy was some form of lunatic or psychopath, and it seems pretty clear to me at this point that he was inspired by terrorists. But there's no evidence that he was a terrorist--that is, that he was hooked into some organized network. Lots of people do terrible things in the name of their religion--just ask George Tiller. Their acts are, as the Catholic Church says, "sins that cry out to heaven for vengeance". But they are no more indictments of a community than the acts of that Korean kid who went crazy at Virginia Tech.
There is absolutely no political lesson to be learned from this. Gun control would not have stopped a commissioned officer from obtaining guns. Barack Obama had no power to stop this. Infectious PTSD is a lousy theory. And nations certainly do not--and should not--shape their foreign policy around the possibility that a random psychopath will start shooting up a crowd. Evil people do evil things. That's all.
