The prisoner volunteered. I’m not sure what better circumstances we could get.

I really think death penalty opponents just don’t want to break the seal. Right now the idea that it’s “experimental” is the only argument against it. Prove it works, and it will quickly become the go-to method.

Opposition got their biggest victory when they got drug companies to stop providing the traditional 3 drug cocktail that has worked for decades. Now they argue every other method is either cruel and unusual (new drugs or older methods) our too experimental (inert gas asphyxiation or opioid overdose) when those latter methods are likely far more humane and much harder to stop up the supply.
