Drawing from a wide range of sources—including historical case studies of prisoner radicalization reaching from Gandhi and Hitler to Malcolm X, Bobby Sands and the detainees of Guantanamo; a database of cases linking prisoner radicalization with evolving terrorist threats ranging from police shootouts to suicide bombings; interviews with intelligence officers, prisoners affiliated with terrorist groups and those disciplined for conducting radicalizing campaigns in prison— The Spectacular Few imagines the texture of prisoners’ lives: their criminal thinking styles, the social networks that influenced them, and personal “turning points” that set them on the pathway to violent extremism. Hamm provides a broad understanding of how prisoners can be radicalized, arguing that in order to understand the contemporary landscape of terrorism, we must come to terms with how prisoners are treated behind bars.
