This article explains that in trying to put Dennis McGuire to death for raping and killing a pregnant woman, Ohio was unable to get their usual death penalty drug, pentoarbital, Instead they are going to use two drugs in combination (a sedative and a painkiller) that have not been tried together before in the US. They tried to use this method on another man before, but he "won a reprieve from Gov. John Kasich while the prisons agency studies the feasibility of his desire to donate a kidney to his mother and his heart to his sister after his death." The article then goes into a little more detail about his crime, but if you wanna read it go look at the link. It talks about other state's drugs used for the death penalty, then it says that McGuires lawyers say that the court didn't get to hear all of the abuse and suffering of his childhood, while the prosecution said that he should be put to death because of the nature of his crime.

I do not really want to open this can of worms, but oh well. As far as the death penalty goes, I think it should be used in some situations. There are some crimes that are just so horrible that the criminal should be put to death to prevent future problems. I don't have enough info to know if it should be used in this case, however. As far as the main point of this article, the whole untried-2-drug thing, I am not sure. Is is cruel and unusual punishment? A painkiller and a sedative sure doesn't sound cruel, but it is untried so who knows? I am thinking that they should get his consent to do it that way, and if he says no,  they need to find a different way.
