The State of Georgia is about to execute a man convicted on the basis of eyewitness testimony that has, almost in its entirety, been retracted. There was no physical evidence against him. A former US president, a former FBI Director, a beavy of unpaid legal experts, and a group of former wardens who have all carried out death penalties, have all called for Georgia to stop the execution. But it has refused – even though another man has confessed to the murder, and even though that man was one of the eyewitnesses who put Troy Davis on Death Row. Constrained by law to decide based on narrow legal grounds that have nothing to do with the now recanted eyewitness testimony, the US Supreme Court refused to stay the execution. And as I write this, we are moments away from what appears to be the most unjust US execution of modern times.
