Uh, NO. There were people watching the exits of the consulate before anybody else showed up and the first large group on scene was a bunch of guys with AKs and RPGs. The Libya "protests" were entirely manufactured by AQ and the local imams to provide cover for the attack. As for the Egypt protests, those had much, much more to do with the Blind Sheik than a bad arabic dub of a stupid trailer. Now, all the follow up protests were about the rumors of the trailer being spread by your local islamic fanatics, but not Libya and Egypt.
Also, it's not comedy central who quashed the Mohammed episodes, but Viacom, their parent company.
