A Texas death row inmate, Khristian Oliver claimed his constitutional rights were violated by jurors bringing bibles and discussing the bible during deliberations of his punishment. The Fifth Circuit Court of Appeals held that it was not error, that the decision of death penalty was not harmful error by the jurors having bibles and discussing that whomever kills by an iron rod shall die. The United States Supreme Court refused to hear the case, on April 20, 2009.
My friend Winston Cochran was the appellate attorney for the defendant. Winston teaches Bible studies. Maybe he was trying to lose this case? He failed to rely on Robinson v. Polk, 438 F.3D 350, 368-376, that the key issue is whether the bible(s) were a deliberative aid and not just personal use.
A jury needs to be free of external influences under the Sixth Amendment.
