The thread is not about the prison system, although that is a discussion that would likely deserve a thread of its own.
The thread is regarding the death penalty and the best/most effective/humane way to carry out executions. And I've come up with a solution which will also stir some new debates within the Huddle, I'm sure.
First of all, since the death penalty is legislated at the state level, why not allow each state to hold several options when it comes to methods of execution? For example, the death penalty is obviously a part of Arizona law; so why can't Arizona include several death penalty options, examples as the guillotine, firing squad, lethal injection and the electric chair. Then, when the death penalty is arrived at by a jury, the convicted is then given some time during the course of the appeals process, to select his own method of execution.
In cases where the convicted is considered to be of diminished capacity or is otherwise not mentally capable of making such a decision, a third party (neither the state nor the convicted) conservator of the convicted will make the decision.
