This Aug. 22, 1991 photo shows Troy Anthony Davis entering Chatham County Superior Court during his trail in the shooting death of off-duty police officer Mark MacPhail. The jury that unanimously found Davis guilty and sentenced him to death no longer agree about whether they did the right thing. Davis’ attorneys have delayed his execution three times, less than 24 hours before he was to be executed, in one instance, by raising doubts about witnesses. (AP Photo/Savannah Morning News)
