When the original news broke about Alabama using nitrogen, my wife woke me up by hitting my arm to tell me - because I've been saying that is the most humane possible method for the last 16 years.
I think the death penalty is stupid to begin with, and am kinda over talking about its merits after years of debate team in high school and college. But trying all of these seat-of-pants cocktails of midazolam and pentobarbital etc, and then inventing all of these ridiculous devices that require two people to push buttons at the same time so no one ever really knows whose button actually killed the person.... it's just needlessly complicated and dumb. Not to mention the fact that the legal costs involved in defending appeals and housing someone on death row are much higher than the cost of a life sentence anyway. And that's leaving aside the statistically significant number of wrongful convictions...
I mean, we shouldn't have the death penalty. But if we're going to, it should be by nitrogen hypoxia.
