To me, the most logical explanation is they are leftist idiots, and believe muslims are persecuted, and the video seemed a good explanation. Wasn’t the State Dept Twitter apology BEFORE the attack on Benghazi? People are making this too complicated. The other thing is, if the CIA or someone was doing something, would they really tell the State Dept?
The first apology from the Cairo embassy was early in the morning before the protesters showed up there. 20+ hours before the Benghazi attack.
