“"As governor, I came to believe that the death penalty would be a just punishment for certain, especially heinous crimes, such as the murder of a child or the murder of a police officer. The events of September 11 convinced me that terrorists also deserve the ultimate punishment." --June 2003”

Reflections on the Guillotine (1957)
Context: Capital punishment is the most premeditated of murders, to which no criminal’s deed, however calculated, can be compared. For there to be an equivalency, the death penalty would have to punish a criminal who had warned his victim of the date on which he would inflict a horrible death on him and who, from that moment onward, had confined him at his mercy for months. Such a monster is not to be encountered in private life.

"The Privilege of the Grave" (1905)
Context: As an active privilege, [free speech] ranks with the privilege of committing murder: we may exercise it if we are willing to take the consequences. Murder is forbidden both in form and in fact; free speech is granted in form but forbidden in fact. By the common estimate both are crimes, and are held in deep odium by all civilized peoples. Murder is sometimes punished, free speech always.

I Ain't Got Time To Bleed (1999)
Context: How come life in prison doesn't mean life? Until it does, we're not ready to do away with the death penalty. Stop thinking in terms of "punishment" for a minute and think in terms of safeguarding innocent people from incorrigible murderers. Americans have a right to go about their lives without worrying about these people being back out on the street. So until we can make sure they're off the street permanently, we have to grit our teeth and put up with the death penalty. So we need to work toward making a life sentence meaningful again. If life meant life, I could, if you'll excuse the pun, live without the death penalty.
We don't have it here in Minnesota, thank God, and I won't advocate to get it. But I will advocate to make life in prison mean life. I don't think I would want the responsibility for enforcing the death penalties. There's always the inevitable question of whether someone you gave the order to execute might truly have been innocent.
