In a move that has reignited debates on the morality of capital punishment, the US Supreme Court has temporarily blocked Alabama’s first nitrogen gas execution. The inmate, Kenneth Eugene Smith, was due to be put to death by a method critics have likened to ‘human experimentation’. The court’s intervention came late, but it came, offering a reprieve that felt as much about legal process as it did about humanity.
The court’s decision is not a final ruling on the constitutionality of nitrogen hypoxia, but it has thrown a spotlight on a practice America still clings to, while Britain watches from a distance, with a moral authority that feels both comfortable and uncomfortable.
This is not a tale of two justice systems, but rather a study in how societies evolve their understanding of punishment. In the UK, we abolished capital punishment in 1965. Our last hangings were in 1964, carried out in private, away from the public eye that now scrutinises every state-sanctioned death in America. The debate here is not about methods, but about the very principle. We have moved on, or so we tell ourselves.
But the human cost of this difference is stark. In America, death row inmates wait for years, often decades, in a limbo of appeals and stays. Their families wait too. Smith’s case is a perfect illustration. He was convicted in 1996 for a murder-for-hire plot. He survived a previous execution attempt in 2022 when lethal injection was botched. Now, he faces nitrogen gas, a method that has never been tried on a human being. The state of Alabama called it ‘perhaps the most painless and humane method of execution known to man’. But the court’s block suggests discomfort with that claim.
The cultural shift here is subtle but profound. Britain’s stance on capital punishment is part of a broader identity, a sense that we are above the barbarism of state killing. We lead international campaigns against it. We refuse to extradite suspects to countries where they might face it. It is a moral high ground, but one that costs us nothing. The human cost is borne elsewhere.
On the streets of London, people rarely talk about executions. The death penalty is a historical footnote, a relic of a more brutal age. But Smith’s case, and the court’s intervention, stir something. It reminds us that justice is not always just. It is often about power, about what a state can do to a person.
The Supreme Court’s block is not a victory, but a pause. A chance to ask: what are we doing? For Britain, it is a chance to look across the Atlantic and see a reflection of our past. We may have moved on, but the questions remain. Is any killing by the state ethical? And if we lead the way in rejecting it, what does that say about us?
Perhaps it says we are still trying to be civilised. And in a world where such distinctions matter, that is something.
