"Some mistakes are fixable. Wrongful conviction and subsequent execution is not. In this program, ABC News correspondent John Donvan traces the history of the death penalty in the U.S. since 1935 while capturing the views of George W. Bush and Illinois governor George Ryan. Then, Gerald Kogan, former chief justice of the Florida Supreme Court, and Dudley Sharp, director of Justice for All, join anchor Chris Wallace to discuss the use of DNA evidence to overturn death penalty convictions and to debate whether America's criminal justice system is functioning or failing."--Container.
