It appears there were two attacks, right? The first one was rather unorganized and was probably the result of anger over the video…hours later a second attack, more organized.

So it would seem to follow that the militia groups joined in. Would it take more than a few hours to organize this second attack? Were they also angry about the video? I would assume they were. But they probably had other motivations as well.

I think it was an opportunistic attack, by extremist militants that was precipitated by the first wave of anti-Americanism over the film .
