The investigation by the inspector general’s office aims to cover 54 prisons, 50,000 inmates and 20,000 corrections officers. In a previous inquiry, the office took a year to look into a single prison.
The Freethought Books Project provides donations of secular and freethinking literature to prisoners, inmates in mental hospitals, books to prisoners projects, and others in need. The program also connects inmates to volunteer pen pals, who correspond with secular humanist, atheist, and other inmates who are connected to the project. This project has been administered by the Center for Inquiry since 2013.
