A federal appeals court has refused to stop the scheduled execution of Idaho inmate Paul Ezra Rhoades.  The San Francisco-based 9th U.S. Circuit Court of Appeals on Wednesday denied Rhoades' plea to halt his lethal injection scheduled for Friday. Rhoades' lawyers argued that Idaho's new lethal injection policy is flawed and amounts to cruel and unusual punishment. But a unanimous three-judge panel upheld the ruling of a lower court that said the new guidelines complied with the U.S. Supreme Court's approval of lethal injection in a 2008 ruling. In failed attempts for clemency Rhoades has told the Idaho Commission of Pardons and Parole he's genuinely sorry for the pain he caused victims and their families.  Victor Rodriguez, a detective who worked on the cast over 20 years ago,  says he's not sure how changed Rhoades is, even after more than two decades in prison. There are those who object to the death penalty in Idaho. The objectors say they will be at the Idaho penitentiary on Friday morning giving voice to those who believe that capital punishment is not the answer.
