No, but the idea of their attacking that facility to get these two guys back makes more sense than anything else so far. I’m sure there were strange weapons deals going on and and I’m sure Stevens was involved in it and they may have wanted to get rid of him if he was interfering with their weapons flow, but it has always seemed to me that their objective was something much more immediate.
The AQ group obviously played on the date, 9/11, to get support from the mob, and they certainly knew in advance that the ambassador was going to be there and for propaganda purposes, they probably hoped to capture him alive and parade him around a bit, humiliate him and then kill him publicly. (Unfortunately for them, he seems to have died before they could do much more than a few fist pumps, allahu akbars and a short trophy parade with his body.)
But it still seemed to me that their focus was something else, and if they thought or knew that two of their buds were being held there, this would explain their persistence and their interest in the facility, even after they thought and then knew that Stevens had been killed.
"But Mr. Abu Khattala insisted that he had not been part of the aggression at the American compound. He said he had arrived just as the gunfire was beginning to crackle and had sought to break up a traffic jam around the demonstration. After fleeing for a time, he said, he entered the compound at the end of the battle because he was asked to help try to rescue four Libyan guards working for the Americans who were trapped inside. Although the attackers had set fire to the main building, Mr. Abu Khattala said he had not noticed anything burning.

IIRC, the Muzzies were talking about getting someone released from guantanamo....
