The new documentary, "Long Distance Revolutionary: A Journey with Mumia Abu-Jamal," chronicles Abu-Jamal’s life and work as a journalist, writer and public intellectual, even as he spent some 30 years on death row in Pennsylvania. In 1982, Abu-Jamal was sentenced to die for allegedly killing Philadelphia police officer Daniel Faulkner. He has always maintained his innocence. Then, last year, the 3rd U.S. Circuit Court of Appeals set aside Abu-Jamal’s death sentence after finding jurors were given confusing instructions that encouraged them to choose death rather than a life sentence.
