Death row prisoner Troy Davis is scheduled to be executed tonight at 7:00 p.m. despite widespread concern Davis is an innocent man. In 1991, Davis was convicted for murdering a white police officer. Since then, seven of the nine non-police witnesses have recanted their testimony. There is no direct physical evidence tying Davis to the crime scene. We speak to Rep. John Lewis (D-GA) and Troy’s sister, Martina Correia. [includes rush transcript]
