There are many arguments to be made in favor of Proposition 34, foremost among them that life without parole is a more cost-effective punishment for convicted murderers, not to mention that the notion the death penalty works as a deterrent to homicide is patently absurd.
The greatest argument against the death penalty, however, stands on moral ground rather than fiscal or psychological: The death penalty is inherently immoral because our imperfect justice system leaves open the possibility that an innocent person might be convicted and ultimately executed. There's no fixing that mistake.
If even one factually innocent person is ever executed -- and don't kid yourself, it's surely already happened -- then justice has not been served.
Vote YES on Proposition 34.
