In Georgia, supporters of death row prisoner Troy Davis have been holding an around-the-clock vigil outside the Atlanta building where the Georgia Board of Pardons and Paroles will decide today whether to halt this week’s planned execution. Under Georgia law, only this board has the authority to grant clemency, not the governor, as is the case in many states. Davis is scheduled to die at 7:00 p.m. on Wednesday by lethal injection. Former FBI Director William Sessions has become the latest high-profile figure to call for the execution to be put off. In a letter to the Atlanta Journal-Constitution, Sessions writes, “[T]he evidence in this case — consisting almost entirely of conflicting stories, testimonies and statements — is inadequate to the task of convincingly establishing either Davis’ guilt or innocence. What do we want, Justice, when do we want it, now, thank you.”
