Since the September 11, 2001 US-Terrorist Attacks there has been an overwhelming increase in documented cases of violent acts of extremism made possible by radical terrorist recruitment of domestic gangs. These new, global criminal alliances combine tech-savvy radical extremists and the local knowledge and manpower of U.S.-based gangs creating a greater potential for biological attacks. As a result, both law enforcement and intelligence agencies have been forced to align their coordination efforts to a greater extent with colleges, universities, private infrastructures, and the military to shift national security efforts from reactive to proactive. D. Darell Dones examines the parallel terrorist-gang activities and prevailing psychosocial factors that explain the varying radical beliefs, causations, and behavioral mindset of these criminal partnerships.
