In this article, the authors apply the four-phase radicalization model proposed by Silber and Bhatt 1 1. M. Silber and A. Bhatt, Radicalization in the West: The Homegrown Threat (New York: New York City Police Department, 2007). Available at http://www.nyc.gov/html/nypd/downloads/pdf/public_information/NYPD_Report-Radicalization_in_the_West.pdf (accessed 19 December 2011). View all notes to a case study of Australia's first convicted terrorist, Jack Roche, based on communication with Roche after his incarceration and on a qualitative analysis of his trial. In doing so, they examine the validity of the four-phase model to a case of “home grown” terrorism and dissect the role of religion in the radicalization process. To conclude, the authors find that religion plays a far lesser role in radicalization toward violent extremism than the policy response contends and this has implications for counterterrorism programs that aim to address the drivers of violent extremism.
