Texas is preparing to execute a 30-year-old African American for a crime he’s openly known not to have committed. Kenneth Foster was sitting in a car 27 yards away when a friend murdered an unarmed man in his home. Foster was convicted under a controversial Texas law that faults an accused suspect for failing to anticipate a crime. A federal appeals court has declared Foster’s sentence marks a constitutional defect. But a state court can’t overturn his conviction because no new evidence has been introduced. Supporters are calling for Texas Governor Rick Perry to grant clemency before Foster’s August 30th execution date.
