Regarding “How lethal injection system went wrong” (Tulsa World, June 22): After reading the horrific details of the murder of Stephanie Neiman, I’ve concluded that any suffering Clayton Derrell Lockett may have experienced during his execution is rendered irrelevant by the savage and remorseless nature of his actions. The process went wrong and that should be addressed; executions should be conducted predictably and properly. But to use an archaic phrase, I don’t give a tinker’s damn how much pain or discomfort Lockett may have endured. Back in the day, when a horse broke its leg, it was shot. Lockett didn’t deserve that much mercy.
