As yet another execution in the USA is botched, it's worth pointing out that the death penalty there is designed to be Cruel And Unusual by design; by design it causes the maximum amount of stress and trauma to the condemned person, even when it is not botched.
Even when everything goes smoothly to plan, the methods used to judicially murder people — gas chamber, lethal injection, electric chair, and firing squad — draw the process out as the condemned is marched from their cell to the execution chamber, and tied to a gurney, a chair, or a post, and any further preparations made before the execution itself is delivered.
And then when the process itself is started, it is not instant; the choices of chemicals and gasses used, the action of electrocution or of shooting somebody, make for minutes of sheer torture in agony for the final minutes of life.
By contrast, the long drop method of hanging as used in Britain in the first half of the 20th Century at least makes for an instant death from the drop, and the whole overall process itself was over and done with from beginning to end in a matter of seconds.
For those with both a morbid curiosity of the subject as well as those who feel a moral obligation to further inform themselves, the fictionalised documentary film Execution and the BBC's Life and Death Row actual documentary series make for essential viewing.
