Mumia Abu-Jamal has spent over three decades on death row in the throngs of the American prison system. Prior to his conviction in 1981 for the murder of a white police officer, Jamal was a political activist and President of the Philadelphia Association of Black Journalists. Critical evidence vindicating Jamal was withheld from the trial prior to the issuance of the death penalty. Forensic experts believe he was denied a fair trial. On December 7, 2011, the Philadelphia District Attorney announced that prosecutors would no longer seek the death penalty for Jamal. He remains imprisoned for life without parole and continues his work as a journalist from his jail cell in Pennsylvania.
