"Whatever we know about these executions, the known unknowns are greater. Because the states will not share them, we don't know the dosages of the drugs administered. We don't know the drugs' manufacturers or their quality-control procedures. We mostly don't know the credentials of those administering the drugs. More importantly, the defendants don't know any of this, either. Without this information, those sentenced to execution cannot challenge the execution procedures in court nor check for possible medical complications. State execution-secrecy laws, routinely upheld by lower courts but untested before the Supreme Court, prevent this basic level of prophylactic Eighth Amendment protection. If death by torture is not cruel, defendants contend, what is?"
