It's a plot!
What if the "anti-muslim" movie (actually a movie trailer on you-tube) was really an Al-Qaeda plot to stir up protests which right-wing jihadists could take advantage of (as they did in Libya)? After all, it was the anniversary of 9/11/01. Everyone had been on high security alert on 9/11/11, that level slipped for the 11th anniversary. But how could it have been prevented?
I fully expect that the Dept. of Homeland Security will follow the lead they've always followed with the TSA and "fight the previous war" by insisting on pre-clearance of all material posted to you-tube (or other video sites).
And no postings longer than 30 seconds, please.
And verified identity for all posters which will be checked against the "no posting" list of known terrorist movie makers.
Or maybe we should just investigate all movie makers for their jihadist tendencies. I believe I know a senator who has a list of known sympathizers...
