Mumia Abu-Jamal is a political prisoner who has been imprisoned for over 20 years. He has been imprisoned for the murder of Daniel Faulkner, a Philadelphia police officer. The trial was pitted against Mumia after he was given a court appointed lawyer against his will. Mumia is a civil rights activist and a very outspoken critic of the corrupt and racist system, particularly in Philadelphia where he resides. The trial was another example of racism in our judicial system and how a many who is fighting for freedom can be silenced so easily. The evidence that was used in his trial is now being rebuked by new testimony and photos. To this day he is still on death row for a crime he did not commit. Here is a link to the free Mumia site. This can give much more information then I can.
