The states all pretty much use the same stuff. A knock-out drug, one that stops breathing & one that stops the heart. Each one is given in a lethal dose all by iteself.
" One to paralyze, one to anesthetize, and one to stop the heart. "
Why is it necessary to give the drug to paralyze? If the heart is stopped there won't be a lot more breathing.
I have heard that the objections are to the paralyzing drug which they say can suffocate the convict.
That's not what it sounds like to me. There was no mention of a "knock-out drug" in the news reports. That would be humane. Anyway, I'm against capital punishment, so what do I know?
