Che, while I agree that the administration probably dropped the ball on this one, it has to be taken into account that there are probably hundreds of threats made daily. Deciding which ones are legit and which ones are rumors is one heck of a lot easier using hindsight. And saying "major newspapers" doesn't do anything for me in terms of credibility 
If the US took every threat seriously, the nation would have to close down.
