What happened to Pike was gruesome. No one deserves what she went through, not even those who commit horrible crimes

Botched executions are nothing new in US history. In the era when hangings were common, some condemned people were decapitated. Later, when the electric chair was in vogue, every now and again, someone would catch fire during an electrocution. And nitrogen hypoxia, the US’s newest execution method, has already proven notoriously unreliable.

But, of all of the ways we have tried to execute people, lethal injection has the worst track record. More than 8% of all lethal injection executions have been botched. Most of them resulted when those charged with carrying them out could not find a usable vein.

Three-quarters of nations have rightly abolished capital punishment in law or practice, but killing by the state has surged in the US

What is the kindest way to kill? That’s the question being asked once more following Tennessee’s failed attempts to execute Christa Pike for the brutal murder of a classmate, Colleen Slemmer, when she was 18. The 50-year-old was taken to a medical facility, her condition unknown, with witnesses describing her snoring loudly around 40 minutes after receiving two injections of pentobarbital on Wednesday. It is the second botched killing in months, prompting Tennessee’s governor to order a halt to executions.

Lethal injection was supposed to be the humane alternative to firing squads and electric chairs. They in turn were seen as an improvement on hanging, which looked much like lynching in a system disproportionately handing the death penalty to black men. The age and ill health of those executed, and the ethical refusal of most medical staff to be involved, may contribute to botched injections. But analysis of autopsy results has provided compelling evidence that suffering is inherent; injections – especially those involving paralytic drugs – have merely disguised it. What is described as safeguarding the dignity of prisoners is really about reducing the discomfort of witnesses who would otherwise see their suffering.
