Inmate Seeks to Challenge Alabama's Execution Method

Alabama death-row inmate Tommy Arthur says she wants a chance to argue in court that the procedure the state plans to use this month to execute her may be unconstitutional. In 2011, the state changed the first of three drugs administered during lethal injections, substituting pentobarbital when supplies for sodium thiopental ran low. Arthur and her lawyer argue that the change could result in cruel and unusual punishment, and should be significant enough to trigger an appeal. WKRN News 2 Nashville has the story.
