Islamic Extremism Online?

Islamic Extremism Online?

One of the biggest threats to young British, muslims today are extremist Islamic groups that operate in and through the U.K. With case studies and reports from MET Police Intelligence and the International Center for the Study of Radicalism many are now realizing the potential role the Internet has had to play in terrorist atrocities around the globe. Specifically in relation to the 7th July bombings, the bombers where suspected to have created links to Al Qaeda and Jemaah Islamiyah on line.

Through email and exchanges of radicalist on-line media they began to travel to training camps, ( in particular Mohammad Sidique Khan traveled to extremist camps in Pakistan and Afghanistan in 2003) until finally they planned and executed their bombings in London on 07/07/2005.
To better understand this hypothesis that the internet is a contributor in indoctrinating disenfranchized peoples to militant organizations, ive posted a link to the ICSR's report entitled "The Challenge of Online Radicalization: A Strategy for Action"

But we must also question "Can the internet solely be responsible for turning someone into a terrorist?" Is there a line that must be crossed in order for a zealous extremist to turn into someone who perpetrates murder and terrorism in the name of ideology?
