Now that the U.S. Supreme Court has refused to hear four inmates’ challenge to the specifics of the lethal injection process, federal executions are expected to resume next week. In July 2019, Attorney General William Barr declared an end to a federal moratorium on executions that had been in effect since 2003.
The inmates alleged that the Justice Department’s execution instructions, which call for the use of a single dose of pentobarbital, a barbiturate that is normally used as a sedative, violates the Federal Death Penalty Act.
They claimed that the law requires federal executions to be carried out “in the manner prescribed by the state” in which the prisoner was convicted. Pentobarbital is not used in Arkansas, Iowa or Missouri, the pertinent states in their cases. They were hoping their executions would have to be carried out using drugs the federal government does not possess, sparing them at least temporarily.
My research on America’s methods of execution indicates that the promised benefits of lethal injection – a quick, painless death – have never come true. And there is no longer a national consensus about what drugs, or drug combinations, are best for putting people to death.
The history of lethal injection
Lethal injection has been legal in the U.S. since 1977, although its history can be traced back to the late 19th century.
At that time, a state commission in New York looked at alternatives to hanging, which was then the most common method of execution. Hanging had been discredited because of several gruesome botched executions. The commission discussed lethal injection, but the state ultimately chose electrocution as its preferred method.
In 1953, Great Britain’s Royal Commission on Capital Punishment also considered lethal injection as a possible replacement for the gallows, but ultimately chose not to recommend its use. The Royal Commission heeded medical experts’ warnings that the drugs could cause problems and that it might be hard to find the veins of the condemned – fears that have become reality in the U.S. in recent years.
Others have continued to advocate for lethal injection – including people who oppose government executions altogether. Albert Camus, the French philosopher who was one of the 20th century’s leading opponents of the death penalty, famously argued that that if France was to continue using capital punishment, it should do so with “decency” by using an “anesthetic that would allow the condemned man to slip from sleep to death.”
Replacing the electric chair
During the last quarter of the 20th century, similar beliefs about the allegedly more humane nature of lethal injection surfaced in U.S. state legislative debates seeking an alternative to the electric chair.
Oklahoma became the first state formally to adopt lethal injection as its method of execution. At the time, it chief legislative proponents claimed that it would be a dramatic improvement over the “inhumanity, visceral brutality, and cost” of the electric chair.
Oklahoma chose lethal injection, as legal scholar Deborah Denno writes, “despite the fact that the procedure had never been medically or scientifically studied on human beings.”
By 2002, 20 years after Texas became the first state to carry out an execution by lethal injection, 37 states had made it their default method.
How lethal injection works
Over that period, a consensus emerged among death penalty states about the exact mix of drugs that would be most effective. A three-drug protocol was developed, combining an anesthetic (usually sodium thiopental) with a paralytic agent (pancuronium bromide), and a drug to stop the heart (potassium chloride).
However, since 2010, shortages of those drugs have caused the consensus to disintegrate. Death penalty proponents complained that the shortages resulted from opponents’ efforts to end the death penalty by any means, saying the activists had pressured companies to stop making those drugs.
Complaints about an artificially created drug shortage also found their way onto the pages of Supreme Court opinions. In the 2015 Glossip v. Gross decision upholding lethal injection, Justice Samuel Alito wrote that the court should not let condemned inmates delay their dates with death, because “anti-death-penalty advocates pressured pharmaceutical companies to refuse to supply the drugs used to carry out death sentences.”
States search for alternatives
Since 2010, states have gone their own ways in search of supposedly humane and efficient methods for carrying out death sentences.
The Death Penalty Information Center, a national clearinghouse for analysis and information on issues concerning capital punishment, reports that in the past decade eight states have used just one drug, usually a lethal dose of an anesthetic. Fourteen states have employed pentobarbital. Seven have used midazolam as part of a three-drug protocol. Nebraska has used fentanyl, a powerful opioid, and Nevada has authorized its use.
Other states have chosen nitrogen hypoxia, which an inmate inhales and which kills by depriving the body of oxygen, as an alternative to lethal injection. Additional alternatives condemned inmates can choose include the electric chair in Tennessee, firing squad in Utah and hanging in New Hampshire. Of these, only Tennessee’s electric chair has been used recently.
Lethal injection’s continuing problems
From 1982 to 2010, 7% of all lethal injections were botched, making it the most error prone of America’s execution methods.
Since then difficulties associated with lethal injection have multiplied.
They include cases in which guards have had trouble finding a usable vein for an IV line, cases in which inmates have suddenly gasped for air or shown signs of consciousness long after the drugs started flowing, and others in which it took much longer than the expected time for the condemned person to die.
There have also been several badly botched lethal injections involving different drugs and protocols. Three of them occurred in 2014 alone.
Dennis McQuire gasped for air for 25 minutes while the drugs Ohio used in his execution, hydromorphone and midazolam, slowly took effect.
Clayton Lockett in Oklahoma died of a heart attack – not the drugs – 43 minutes after the start of his execution. Joseph Wood repeatedly gasped for one hour and 40 minutes before his death was pronounced in Arizona.
In 2018 executioners in Alabama tried for two and a half hours to find a vein, leaving Doyle Lee Hamm with 12 puncture marks, including six in his groin and others that punctured his bladder and penetrated his femoral artery, before his execution was called off.
Such deeply troubling failures have not moved a majority on the current Supreme Court to recognize that they are constitutionally problematic. Yet they are evidence that lethal injection has not been the answer to America’s centurylong quest to find a method of execution that would be safe, reliable and humane.
