Hillary and Obama had that video ready to go as their excuse, there’s little doubt about that. They didn’t have time to “find” it, they had to have already known of it. How they knew of it is the real question.
The suspicion that Nikoula was working for the gov’t when he made it would explain that. If so maybe his arrest afterwards was a cover.
Montagraph’s information is gone now that he has made his videos private and he is a real nutty guy which didn’t help his credibility. But the details he laid out didn’t hang on his credibility.
What he found is that Nakoula made his film to show in some small theater in Los Angeles (IIRC the city) and he did ... to almost no one. There were four iterations of the video as a post above tells. He wasn’t the one who put it on Youtube. Or not the only one. Time has degraded my memory on that point.
There was another Youtube account, associated with several similarly named accounts, that used a logo with a peculiar font, who posted the video. In a very thorough image search the only other instance of that font was used by Stanley Inc. A State Dept. contractor. All those Youtube accounts disappeared quickly after Montagraph’s first video.
