The NY Times published a lengthy story by David Kirkpatrick Saturday which attempts to explain what took place last September 11th in Benghazi. Much of the story confirms things reported elsewhere, but the author comes to a different conclusion about two topics which have ongoing political implications: Who carried out the attack and why.
There is some evidence...that people in Benghazi were aware of the video that night. And yet this is not proof that there was a spontaneous protest. There may have been a semi-spontaneous assault by militants, which is not quite the same thing.
Was this attack, then, a spontaneous reaction to a video or a planned attack? Either way, it was a major security failure. In fact, it's hard to say which horn of the dilemma would make the administration look worse. A planned attack means a failure of intelligence and security. A spontaneous attack suggests security was so lax, little planning was needed to overrun the compound.
