But aside from that, "Voice of the Voiceless" was also the nickname given to Mumia Abu-Jamal, a radio host, journalist, and former black panther who spoke out, exposing the issues faced by those in poor, or underrepresented communities. He was convicted in 1981 for the murder in self-defense, of a Philadelphia cop who had unrightfully attacked Mumia because of his views.
