The career of Donald “D.J.” Vodicka encompassed the rapid expansion of the prison system in California. For sixteen years, he was a prison guard in California’s highest security and most notorious correctional institutions Daily duties included serving meals to gang leaders, proctoring serial killers in lockdown cells, or patrolling exercise yards filled with violent felons while unarmed and outnumbered 1000-to-2. He belonged to an elite unit called the Investigative Services Unit (Internal Affairs), responsible for solving horrific crimes occurring inside the walls. He was retired as a decorated veteran officer, but certainly NOT of his own volition. He became the most influential “whistle-blower”, uncovering the silent secrecy of a group of rogue prison guards who called themselves “The Green Wall.” His book is a true story, a real-life drama of one man’s courage to do the right thing against the California State Prison System that helped in the cover-up. It is an unblinking look at what can go wrong when only one person is willing to stand up and speak for what is right, against almost insurmountable odds. Vodicka’s televised state senate testimony exposed a scandal that led to resignations, transfers, sudden retirements, and reforms of the system that are still underway. The story is a classic tale of the triumph of personal integrity in the most dishonest and crooked institution imaginable.
