The Atlanta Gun Show, held over a weekend in late September, had everything one might need for a coming apocalypse or civil war: flame throwers, hundreds of rifles, thousands of handguns and knives, body armor, survival kits, medical supplies. 
Sprinkled among swords, boxes of sutures and night-vision goggles were the insignia of the modern extremist far-right: bright yellow patches for the Oath Keepers militia group, holsters and clothing engraved with the logo of the extremist Three Percenters. A stall at the back sold paperback copies of “The Anarchist Cookbook,” which describes how to make homemade bombs, along with a book called “Two Component High Explosive Mixtures.”
