Then your thinking on this issue is more in keeping with the thinking in China's system of justice. And having seen what can happen in that system, in any system really, that is a very dangerous position you take.
That's why I support the death penalty. It is the ONLY way you can guarantee that a murderer doesn't kill again.
There is a hole in your reasoning here. Does the premeditated killing an innocent person make you are murderer? And while I think it is a stretch to liken a government wrongly killing an innocent person to a murderer, my thinking is certainly opposite of yours. Ending the death penalty is the ONLY way you can guarantee that an innocent person is never killed again by the state.
Even if you don't buy into that one, your thinking is still flawed. Certainly a murderer can be kept from killing again - at least those on the outside of the prison wall. It is called life without the possibility of parole.
Speaking of holes in logic. What if the prisoner kills a guard? What if he kills a person in jail who is innocent of murder? Is that acceptable in your eyes?
Face it. Both of us are dealing with acceptable risk. I say executing innocents is an acceptable risk and you say allowing a killer to kill again is an acceptable risk.
