IMHO:
The Administration knew Libya/Benghazi was a powderkeg ready to explode .... they were just riding the “al-Quaeda defeated/it’s all good in Libya” pony as hard as they could, trying to get past election day without it blowing up so Obama could tout his foreign policy/Osama killing .... it was the only real ‘positive’ he had since the economy was/is still in the tank. I think those plotting strategy for the campaign had addressed what in the heck they would do if something like the consulate attack happened BEFORE election day (like on the anniversary of 9/11*) ... how would they handle it? Somebody came up with a ‘protest caused it’ idea and they went out looking for something that maybe could spark one .... somebody got lucky and found that video which had hardly any hits for months, but could be twisted into a narrative to reduce a terrorist attack down to something that could be managed and not kill Obama’s re-election.
Then, it happened .... the terrorists didn’t wait until after election day &, on the anniversary of 9-11, they killed 4 Americans. The video meme was waitng to be employed and it was, quickly and relentlessly. It was the pro-active strategy that had been pre-planned for just such an event, sort of like the “countermeasure flares” that are deployed by aircraft when missiles are fired at them ... the missiles are hopefully diverted by/hit the flare(s), not the plane. The Obama admin is now out of ‘flares’ ... but the missiles of truth were diverted long enough for him to be re-elected.
*They didn’t do the obvious to avoid/survive an attack because beefing up security would be a tacit admission that Obama’s bragging that a-Q were ‘on their heels’ was not in fact the truth on the ground.
I give the people running this administration more credit than you.
I don't think they went out looking for something that would absolve them in the event the "Arab Spring" fiction blew up. I think they took steps to create something they could blame such an event on. And I suspect they commissioned somebody to produce it.
Accordingly, I would very much like to see the purported Jew Sam Bacile (i.e., the reportedly Coptic Christian Nakoula Basseley Nakoula or likely Palestinian Eiad Salameh) on the witness stand -- explaining, under oath, exactly how this travesty was financed. And by who. And for what purposes.
