There is a wire-mesh business-card holder on Brad Underwood’s desk in his office at the TAPS headquarters in Sherman. The cards in the holder face Underwood’s chair. “Most of the people who come in here already know who I am,” he said. The real purpose of the holder is to support a button attached to the back, facing the visitor. It reads, “But we’ve always done it this way,” in the middle of a circle with a slash, the international shorthand for “don’t.”
