The arrests came after an undercover FBI agent infiltrated the group and participated in shooting drills in the mountains of northern Georgia, according to a police affidavit. The drills were being done in preparation for what they believe is an impending collapse of the United States and ensuing race war. At the end of the firearms training, the Georgia men wore tactical gear and balaclava hoods while posing for photos with the undercover agent and the photos were later used in the group’s propaganda, the affidavit says.
