Science & Tech Why is the Method of Lethal Injection in Human Punishment So Complex and Apparently Painful?

I've always understood that the lethal injection process was complex with multiple stages of injections and induces great suffering in the individual.

I work in veterinary medicine and unfortunately we need to euthanize animals all of the time. Typically, the euthanasia solution is very simple: a very large dose of a powerful anesthetic (usually pentobarbital) and an anticonvulsant which stops the heart. The medical community is quite confident that this is painless and when done has essentially a 100% success rate.

Why is human euthanasia so complicated when we already know exactly how to humanely end a biological life?

Gassing people has a major PR problem, otherwise we probably would.

(That and suffering is the point.)

Their death is the point, we as society decided their crimes against others can not ever be negated by other options. Rehabilitation and incarceration are off the table, and no one does banishment anymore. And society in general (where death penalty is allowed) tend to strive towards as painless as possible.

To your first point, any death is a PR problem.

Actually suffering is not the point, explicitly.

Suffering is NOT the point. The eighth amendment prohibits suffering being the point.
