John Grisham is known worldwide for his bestselling novels, but its his real-life passion for justice that led to his work with Jim McCloskey of Centurion Ministries, the first organization dedicated to exonerating innocent people who have been wrongly convicted. Together they offer an inside look at the many injustices in our criminal justice system. A fundamental principle of our legal system is a presumption of innocence, but once someone has been found guilty.
