JACKSONVILLE, Fla. – Lethal injection was supposed to be the humane, enlightened way to execute inmates and avoid the pain and the gruesome spectacle of firing squads, the electric chair and the noose.
But now it, too, is under legal attack as cruel and unusual, with the U.S. Supreme Court agreeing this week to hear arguments that lethal injection can cause excruciating pain.
Some supporters of the procedure say the notion that inmates suffer is unproven. And they argue that there is nothing wrong with lethal injection itself; instead, they say, the problem is inadequately trained executioners.
In fact, the man who developed the procedure 30 years ago said it is similar to the simple injections given every day in hospitals.
‘What causes it to go wrong is that the protocols aren’t carried out properly,’ said Dr. A. Jay Chapman, former Oklahoma medical examiner.
If an execution is about as simple as an ordinary injection, what, then, can go wrong?
Deadly chemical cocktail
In the three-drug process used by most of the 38 states that practice lethal injection, sodium pentothal is given first as an anesthetic and is supposed to leave the inmate unconscious and unable to feel pain. It is followed by pancuronium bromide, which paralyzes the inmate’s muscles, and then potassium chloride, which stops the heart.
Foes of capital punishment argue that if the inmate is not properly anesthetized, he could suffer extreme pain without being able to cry out.
That could happen in a number of ways: The executioner could inaccurately calculate the dosage needed for an inmate of a given body weight. Or the executioner could fail to administer the full amount, mix the drug improperly, or wait too long between giving the anesthesia and the lethal substance.
In Missouri, a doctor who participated in dozens of executions was quoted recently as saying he was dyslexic and occasionally altered the amounts of anesthetic given.
