I don't give 2 flying figs where they get the execution drugs if they have proper efficacy. Vets put down millions of large animals annually. I would think we would just use the same stuff on the bad guys instead of all this angst. But SJWs and liberal jackasses have made all of it stupidly difficult Clearly at least some of the pharma companies don't have a moral objections to making the drugs. They just have a don't want to deal with SJWs and stupid liberals objection.
Or we just go back to hangings, firing squads or the guillotine. I'm good with it either way.
