Could be. Or maybe not. Might have been upset about pastor Terry Jones' video "International Judge Mohammed Day" that was uploaded to youtube on Sept 10, 2012 ....or these films mayy have been "go signals" to communicate with operatives rather than provoke them. Whichever it was, or more likely neither, that ended in the Ambassador's death, there were and are some strange games being played.
There was a third video too, most likely the only video that helped spark the attack, and that was the one released on Sept 10 by Zawahiri, otherwise known as He-Whose-Name-Must-Never-Be-Mentioned-In-An-Obama press conference.
