Extremist movements aren't new, but the tragic events in Oklahoma City, New York City, and elsewhere have awakened Americans to this frightening reality within our borders. What sorts of fringe groups exist? Who joins up and why? What do they want and what are they willing to do to accomplish their goals? How serious is the danger? In response to these questions, noted experts John George and Laird Wilcox have teamed up to examine the frayed edges of human behavior. Beginning with a summary of pre-1960 movements, they then discuss conspiracy theories and what motivates extremists. Their thoroughly documented and detailed tour of contemporary groups on the far left and the far right includes recent militia groups making headlines. Included as well is an in-depth appendix on the use of fake quotes and fabricated documentsa staple of many extremist organizations.
