Oklahoma is one of three states where executions have gone awry this year using midazolam as part of a two- or three-drug lethal injection process. Officials in Texas and Missouri, two of the most active death penalty places, are confident in the use of their single drug pentobarbital and show no willingness to slow down. (AP Photo/File)
