What jumped out at me was that this state uses the one drug combo, rather than three - and it's phenobarbital, rather than sodium thiopental (although I know there are supply issues with that drug manufacturer). Phenobarbital can cause seizures, whereas sodium thiopental does not seem to. Although there are issues with sodium thiopental wearing off too quickly, because administration of the dose is not done by medical professionals with dosages tailored specifically. Just because no other inmates physically shook does not mean that it's issue-free.
For me personally, the only way I could feel comfortable with the death penalty is if it were administered in such a way that it isn't cruel and unusual punishment - and if we have eliminated innocent persons from being convicted. I cannot imagine anything more horrifying than an innocent person being put to death, and that death being tortuous. It's all about Blackstone for me - better than ten guilty go free than one innocent man condemned.
There is no proof whatsoever these injections constitute torture. Again, this was several SECONDS, not several minutes, hours or days. If you really want to stretch it, IMO it could be considered cruel and unusual to know the time, down to the minute, of your death. And you really think it's better for ten guilty people to go free than one innocent to be condemned?
Let me give you a brief synopsis on Kenneth McDuff. He was tried and convicted of murder, sentenced to death. He and another man kidnapped two boys and a girl. The boys were then shot in their heads and killed. The girl was brutally raped by both men and they also violated her with a broken broomstick handle, then murdered her as well. The death penalty was overturned, so McDuff got his sentence changed to life, and then guess what, he got paroled. There's one guilty person set free. He was later again convicted for murdering two more women, one of whom was pregnant, and is suspected of killing at least four more.
So there's one guilty man set free, and at least six innocent women and an unborn child paid for it with their lives, and I sincerely doubt any of those six women were granted a kind and peaceful death.
I don't care what drug combo is used in lethal injection. My understanding it the offer is made to the inmate to be put to sleep before the injection is administered. If the inmate chooses to refuse, and then suffers some pain, which again has not been proven, then that is not any kind of reason to go back to the drawing board on how to carry out death sentences. If anything, force the inmate to be put to sleep first, problem solved.
