IMHO, it seems likely that elements of the US government were involved in video from its inception and through its use as PR / propaganda.
It’s just too plainly idiotic, the whole video scenario.
And if you really search contemporaneous news sources, I’m sure you’ll find the video being reported just too stinkin’ early on to not have been put out there by the government.
The government has an “ongoing investigation” into what happened for weeks, but the day of the attack and the demonstrations elsewhere, almost instantaneously the video was a topic of news reporting ? It stinks.
The Cairo embassy was tweeting apologies for the “video” (without specificity) early in the morning of Sept. 11th before the protest crowds had even assembled. Hillary herself used the Cairo embassy twitter account to tweet about it at 4:38 AM Cairo-Benghazi time on Sept. 12th. About the same time Woods and Doherty were making their last stand.
