NYPD report: Radicalization in the West
“The global jihadi-Salafi movement poses a significant challenge to law enforcement and intelligence since the radicalization phenomenon that drives it is spontaneous, indiscriminate, and its indicators are subtle. Identifying whether an individual is being radicalized is hard to detect, especially in the early stages.
“The challenge to intelligence and law enforcement agencies in the West in general, and the United States in particular, is how to identify, pre-empt and thus prevent homegrown terrorist attacks given the non-criminal element of its indicators, the high growth rate of the process that underpins it and the increasing numbers of its citizens that are exposed to it.”
