On this week's installment of the Global Research News Hour radio program, Suzanne Ross of International Concerned Family and Friends Mumia Abu-Jamal brings us an update on efforts by Mumia Abu Jamal to appeal his guilty verdict in the 1981 murder of a Philadelphia police officer, a crime for which his supporters claim he has been falsely accused. We follow with a brief excerpt of a speech by Angela Davis detailing the role of the prison system in reinforcing elite economic power and white supremacy. We then get a perspective from University of Winnipeg Criminal Justice Professor Bronwyn Dobchuk-Land on the parallel role played by prisons in Canada in maintaining the colonialist status quo.
