In July 1993, a gunman opened fire at the San Francisco law firm of Pettit & Martin, killing eight people and wounding six more.

Joe is an entertainment attorney, a fourth-generation Montanan from Shelby, and a serial entrepreneur. After the shooting, an enduring question haunted him: “Is there a reliable way to stop violence without being violent?”
