A death row inmate in Yellow Springs, Ohio, gave Antioch College’s graduating class a taped lesson in civil rights as hundreds protested nearby. Students last month invited journalist Mumia Abu-Jamal, who was convicted in 1981 of killing Philadelphia policeman Daniel Faulkner, to give the commencement address at the small private college about 15 miles east of Dayton. He didn’t talk about his case, the death penalty or the policeman involved in his six-minute audiotape speech. Rather, he softly spoke of the impact one person can have on the world, the topic students had requested, using Nelson Mandela, Malcolm, X, W. E. B. Du Bois and Angela Davis as examples. Just yards away, near the outdoor ceremony, blue, yellow and orange police tape marked off separate spaces where Faulkner’s supporters and Abu Jamal’s supporters quietly demonstrated.
