I don't understand why we need violent ways of capital punishment.
...As opposed to non-violent ways of killing people?
We tried. Then Europe got upset about it. I think one reason they're considering this is because European drug manufacturers are refusing to export to the United States sodium thiopental and other lethal-injection drugs.
I did not realize US had no pharmaceutical industry of its own. We now know the full-proof way Europe can make US succumb to its demands: ban Tylenol exports.
Big pharma is multinational and for tax reasons is usually incorporated in a low tax European state such as Ireland. But even if it weren't, the desire to sell in European markets would keep them from wanted to sell their drugs for executions.
Wasn't the biggest argument against health reform that the high margins in the American market drive the product innovation, which the socialized European medicine, with its low profits would not generate? Or am I forgetting something?
Anyway, poisons are among the oldest pharmaceuticals known to humanity. To produce generic versions of a few chemicals, which have, mostly, been in public domain for generations, you do not need to be "big pharma". You are not talking of a cure for malaria here.
Every little bit of profit counts, especially since there is very little to be made by selling for use in executions. Even if the profits aren't as high as would be liked, there are still some profits to be made by selling to Europe in addition to America for a drug that has already been developed. The argument you refer to is that if the expected profits made from a drug once it has been developed are reduced then those expected profits may not be enough to justify the expected cost of development. The general idea is sound, tho whether the expected profits would truly be lowered to that point is debatable. However, we're talking not merely chemicals, but drugs which accordingly have to manufactured according to regulation and certified as such. If merely killing were all that was required, there would be no need for such niceties, but since the standard is that executions in the US should be conducted as humanely as possible, precise and consistent dosages are wanted.
I'm not a fan of how capital punishment in the US is conducted, but it certainly is odd that those who oppose capital punishment under any circumstances are seeking to prevent more humane methods of execution from being used in hopes that by making executions less humane they will be ended,
