They got it from a cleric in Egypt who mentioned it a Friday prayers.
There is a vid floating around where I guy has tied ‘the video’ back to a sub-constractor to the State Dept. It’s pretty interesting. I can’t post it b’cause I’m on a BBerry.
No question, it helped to gin up protest demonstrations in a variety of wog locales. However, Benghazi was not among them, as any moron reading the New York Times or the Boston Globe would have known a day or two later. Benghazi was a military assault, not a protest demonstration gone out of control.
We have, for example, the testimony of Ethan Chorin, who was in Benghazi with Dr. Thomas Burke of Mass General, Boston. They were there to assist Libyan doctors in setting up an Emergency Room operation at the Benghazi Medical Center. They and the Libyan doctors were slated to meet with Ambassador Stevens Wednesday morning, the 12th.
On the evening of the 11th, Chorin was on the phone with the Ambassador's security detail arranging the meeting, when the call ended abruptly with a shout of "We've got a problem here". Then Chorin and Burke were left to hole up in their hotel listening to sounds of the distant violence. And the Libyan doctors ended up treating the Ambassador unsucessfully at the BMC for severe asphyxia.
IOW, no demonstration, no build-up. Just a sudden surprise attack by Al Qaeda. Which we now know would not have been a surprise, but for the incompetence of the Obama / Clinton State Department.
