Witness to an Execution In the past ten years, one third of the executions in the United States have been carried out in the state of Texas. Since 1924, executions in Texas have taken place in the Walls Unit in Huntsville. The Warden of that prison, Jim Willett, narrates a documentary titled Witness to an Execution. It includes first hand accounts from the men and women who participate in and witness executions as part of their jobs. Guards, chaplains and reporters talk about their work -- detailing what occurs in the minutes before, during and after the execution. The prison employees say they do the job because the vast majority of citizens want it done. Most are affected by the work. Some reach the breaking point and find they can no longer work in the system.
