Tamara, have you visited the Buffalo Bill Historical Center in Cody? Pretty amazing place, (they have the Winchester factory arms collection), it includes about every thing made in the US, and a pretty fair representative history of arms back to hand cannons and matchlocks. The basement has another rather large pile of guns that are just racked side by side to conserve space. Who knows, they may be looking for staff.
Bernie Goetz. Cooper wrote about a guy that had a similar experience as Goetz just a short time later. After the bad guys were down, he simply left, went home. Nobody ever knew who he was.
