Mumia Abu-Jamal is the most recognized death row inmate in the world today. In 1982, he was was tried and convicted for the murder of Police Officer Daniel Faulkner. Since then, the Abu-Jamal trial proceedings have come under scrutiny and today his case is one of the most contested legal cases in modern American history. A former Black Panther and now renowned author, his books and writings in venues as diverse as the Yale Law Review, Forbes, Nation and street-papers for the homeless, have led many to hail him the voice of the voiceless. Justice on Trial navigates the tempest of the Abu-Jamal trial by reviewing the known facts of the case. It demonstrates that the major violations in the Abu-Jamal case -- judicial bias, prosecutorial misconduct, racial discrimination in jury selection, police corruption and tampering with evidence to obtain a conviction-- are not special to this case. Instead, they are commonly practiced within the criminal justice system and account for the disproportionate incarceration of African Americans and Latinos in the United States. The case of Mumia Abu-Jamal is a microcosm of greater problems in the criminal justice system in the United States today. The attention that its many violations have received make the Abu-Jamal case one of the most important civil rights cases of our time.
