The Damage Done by That Newsweek Article May Have Been Exaggerated
If the notorious Newsweek article that claimed a Koran was flushed down a toilet was the result of deliberate disinformation (which is highly likely), then it's also likely that the riots apparently resulting from it were staged. I suspect those riots would have taken place anyway, complete with claims that the “American media” had verified the story of the Koran's desecration.
This story reminds me of the claim that 4000 Jews had stayed home the day of the World Trade Center attack. On the other hand, this current story appears to be better coordinated.
