Factions of this sort are hostile to both the Libyan government and the United States. A protest of the sort whipped up by circulation of this video would be an ideal occasion to press a planned action.

Seems he sent the translation of the perfect agitprop video to just the right people....

"If you're helping these attacks, we're not going to turn a blind eye."?

That is something right-wing extremists in Israel, including its current Prime Minister, need to understand.

The people who killed the ambassador and other americans at the embassy had no good cause to do so. They were evil. We need to stop treating them like victims, soldiers, or mindless masses and start treating them like criminals.

that was in the mob.

Nobody gives stuff like that back, anywhere....

the average joe in the street protesting the movie but part of the clashes, whichever side.

Crowds can be useful for that. One question, among others, is whether the faction that carried out the attck had a hand in whipping up the crowd, or simply noted it and decided 'today's the day, brothers...'.

and who did what and why, is going to be scary and interesting.

for groups in predominantly Muslim countries and doesn't really have any meaning. Like how they are always killing #2 al Qaeda leader. tell me, why have we never seen estimates on al Qaeda's numbers? Why are we spending trillions on Defense when "al Qaeda" at best has a few Ak-47s? al Qaeda is akin to something George Orwell would have written about, an Emmanuel Goldstein if you will.

for the attack.

It's pretty much how they work, how they've always gotten their money, etc.

Just another example of how they exploit muslims rather than defend Islam.

that's even weaker than the usual "group with ties to al-Qaeda".
