In January 1991, another ATF agent, Herb Byerly, asked Hart to join him in arresting Randy Weaver, who was suspected of illegally selling two shotguns to an informant. Hart and Byerly posed as broken-down motorists on a bridge below Weaver’s cabin and made the arrest after Weaver stopped to help them. Hart said at the time he had no idea Weaver’s arrest would lead to a 10-day standoff that would leave a U.S. marshal and Weaver’s wife and son dead. “He felt taken advantage of,” Hart said of the original arrest. Hart joined other federal agents on the hill during the Ruby Ridge standoff and said they worked to find moments of humor in a tense situation. At one point, the ATF agents put up a “toll bridge” sign, pretending to charge FBI agents for crossing the bridge ATF was holding. “It was very stressful because it was a waiting game,” he said.
