The death row prisoner Troy Anthony Davis has asked to take a polygraph test in the hopes of convincing Georgia officials to spare his life before a scheduled execution tonight. Davis’s request comes after Tuesday’s decision by the Georgia Board of Pardons and Paroles to reject clemency. Shortly after the ruling came down, Laura Moye of Amnesty International condemned the board for allowing Troy Davis’s execution to proceed.

Laura Moye: “We are deeply saddened and shocked this morning. We cannot believe that the Board of Pardons and Paroles is allowing a person to go to his death despite the fact that serious doubts about his guilt remain unresolved. We were hopeful that they would act as an effective fail-safe to intervene in this execution.”

Davis was convicted of the 1989 killing of an off-duty white police officer named Mark MacPhail. Since then, seven of the nine witnesses have recanted their testimony, and there is no physical evidence tying Davis to the crime scene. Davis is scheduled to be killed by lethal ejection at 7:00 p.m. EDT tonight. Democracy Now! will be doing a special broadcast outside the prison in Jackson, Georgia, from 6:00 to 8:00 p.m EDT, which can be streamed live online..
