The fools posing as experts on TV

If it is not tragic it would be hilarious.  When the media agree that the suspects are Arabs, they bring experts to speak about the history of Arab involvement in terrorism and why Arabs in the US would do something heinous like that. And when the media agree that the suspects are Indians, they roll out the same experts who speak at length about causes for Indian anger at the US.  And when they are thought to be Chechnyans, they bring back the same experts who speak about Chechnyan dangers.
