It is my contention that the argument is not about this person's innocence. It is accepted that he is guilty. The argument is about the death penalty.
As far as I am concerned there is no reason to commute this guy's sentence. He killed 4 people in cold blood. The very least he could do is show remorse. And part of that remorse would be an acknowledgement of what he did and an apology to the families of the victims. The fact that he has not admitted to his crimes, nor issued an apology, is very telling to me.
There. Fixed it.
