There’s an old Bill Cosby routine, called “Shop”, on the album Why Is There Air? that is quite apposite to the events of the past two days. In it, Cosby describes how his junior-high-school shop teacher tricked the guilty party into tacitly confessing to having put a bullet in the shop class furnace — and without directly accusing the kid or even so much as saying his name. With the right-wing attacks on Pima County, Arizona Sheriff Clarence Dupnik, we’re seeing something rather similar play out.
