The conservative case against capital punishment, which 32 states have, is threefold. First, the power to inflict death cloaks government with a majesty and pretense of infallibility discordant with conservatism.
Second, when capital punishment is inflicted, it cannot later be corrected because of new evidence, so a capital punishment regime must be administered with extraordinary competence. It is, however, a government program. Since 1973, more than 140 people sentenced to death have been acquitted of their crimes (sometimes by DNA evidence), had the charges against them dismissed by prosecutors or have been pardoned based on evidence of innocence....
Third, administration of death sentences is so sporadic and protracted that their power to deter is attenuated. And the expensive, because labyrinthine, legal protocols with which the judiciary has enveloped capital punishment are here to stay.
