How Islamic State is wielding the Internet in new ways

American law-enforcement officials have expressed growing concern about the threat of homegrown terror as federal prosecutors announced the indictment of a New York man, Mufid Elfgeeh, who is accused of having offered support to the rogue Islamic State, which is creating havoc in Iraq and Syria. New York Police Commissioner Bill Bratton said the nation’s largest police force has been trying to stay ahead of an “evolving world of terrorism” -- especially terror groups’ growing sophistication with the use of social media to promote their message and recruit potential “lone wolf” American terrorists. On the one hand, experts caution that terrorist propaganda and recruitment efforts online is nothing new. But even as a handful of Americans attempt to get more engaged with extremist groups, media observers say IS has become one of most sophisticated social media operations yet seen.
