The estimable Ty Alper explains the lethal-injection controversy, now under consideration by the Supreme Court:
If executions do resume, and the courts do not force states to reconsider the three-drug protocol that they all employ, inmates will continue to be paralyzed before they are killed. (The first drug in the protocol is supposed to anesthetize, the second one paralyzes, and the third one kills.) Many people do not know about this aspect of lethal injection. They hear witnesses describe lethal injection as “peaceful,” but don’t realize that such executions have literally been staged to look that way.
