Portrayal of ISIL in American media

Twitter Inc and law enforcement authorities are investigating alleged threats made by Islamic State of Iraq and the Levant (ISIL) militants against the social media network's co-founder and other employees, the company said in reaction to media reports.
   

"We will not be cowed by these sick terrorists," said British Prime Minister David Cameron after Islamic State of Iraq and the Levant (ISIL) produced a grisly video of the mass beheading of Syrian captives by foreign jihadis who allegedly included British fighters. As if the purpose of terrorist attacks in Western countries was to cow and intimidate them.
