First to -- talked to doctor Rick. Halperin director of SMU's Embry human rights program good morning doctor tomorrow. Happy Friday to use -- let's talk about. I guess -- drugs that are used in lethal injection because here in Louisiana I think it would use the same ones. As were used in the if you wanna -- botched execution troubled execution however you were referred to it. In in Arizona -- their doctors. But state obviously I don't think it's a scientific term is that a political term is at an editorial term would you say is a medical professional. Or allies not a medical professional I'm historian. Professor at university. I can't speak to that from medical terms but. Given the normalcy. If you could use that word execution via lethal injection as supposed to be routine and it should take they condemned person -- ten to fifteen minutes. To be put to death so. Really anything that runs longer or much longer than that is clearly as you said trouble botched or just very. Very -- indications that something went awry. Wrong for the people watching Iran for the patient because I made the example earlier of of those -- I had surgery -- yet. You count backward and you don't remember anything you don't feel anything do we know. Medically speaking or scientifically speaking if even though it takes ninety minutes there is any kinda. Suffering -- cruel and unusual punishment to quote the constitution. -- would deep and long lead combination of drug use because some inmates and other states. Have complained. -- burning. And have actually been on the journey rising. So it it really deep. Hands as to what combinations of drugs to three year even ones and how the interact with the inmates system. But it's clearly not. Are overwhelmingly they are not painless. And they clearly are disturbing for people who have to sit there and watched. Whether it's somebody gasping. Over 600 times as an Arizona or somebody catches on fire and and electrocution it goes wrong. It's very disturbing for -- and have to watch them from prison officials have to do. Do you think there's. Any form of the death penalty that is preferable over the other you against the Mohler do you. I think some can lend themselves accrual an unusual punishment others don't. I'm against the wall. I just don't think there's any such thing as a cleaner humane way to kill somebody. Regardless of the method and I suppose the technology from electrocution gas into lethal injections at all. Serious and continual problems if it's just -- myth that people can be killed and humane and clean and painless way. Doctor I appreciate your time I really do and I hope we get a chance hockey again -- -- thank you doctor Rick Halperin director of SMU's -- human rights program.
