Jim McCloskey is an American author and advocate for the wrongfully convicted. He is best known for founding Centurion Ministries, a non-profit organization dedicated to vindicating individuals who have been wrongly accused and unjustly imprisoned. McCloskey started this work in the 1980s after a personal experience of witnessing injustice while volunteering at a prison. His efforts have led to the exoneration and freedom of numerous individuals over the decades. Alongside his advocacy, McCloskey co-authored a book titled "When Truth Is All You Have," which chronicles his journey and the stories of some of the people he has helped. His work has been instrumental in raising awareness about the flaws in the criminal justice system and the importance of fighting for those who cannot defend themselves.
