Many youth often make the jump from a passive supporter and sympathizer of terrorists to active supporter actually engaging in terrorist acts through the internet. The internet can instruct future terrorists how to build bombs, join an organization, fund terrorism, and share information. In many ways the internet serves as a virtual training camp.
Much like the way non-terrorists use social media, the internet has “become a virtual ‘echo chamber’ — acting as a radicalization accelerant," according to a United States Senate Committee.
The Department of Homeland Security has cited three ways that young people find sites to become radicalized: browsing for entertainment; searching for a community to belong to; and looking for information related to heritage, traditions, or ideologies associated with a particular radical group.
A relevant case study of this is the example of American Colleen LaRose, although not a youth, better known as "Jihad Jane." LaRose found herself going through a tough time. After attempting to kill herself, she converted to Islam. Using the internet, she went from a passive supporter of terrorism to and active supporter, and she was enlisted by an al-Qaeda operative to fly to Sweden and kill the author of a cartoon depicting the Prophet Muhammad's head on a dog. She was arrested when caught by the FBI in 2009.
