The person being put to death by the prison has a right as a human being, even if they have robbed others of that right, to die a quick and relatively painless death. I understand the situation that leads into the pharmacy remaining anonymous, but feel there should be some accountability for what they produce. If they get a situation like that Oklahoma man that got to writhe in agony for the better part of an hour, the pharmacy should be held accountable for that, and their name and concoction made known.
I will go on record saying that I feel vengeance does not equal justice, but I support the killing of inmates who show no capability of rehabilitating from their crimes. I'd also state that it should only be used in situations where there is indisputable, no shadow-of-the-doubt evidence showing they did what they're accused of doing, and they show no remorse for having done it. But that's an argument for another thread, I think.
