I nonetheless join the entirety of the Court’s opinion, including the final portion, ante, at 417-419 ? because there is no legal error in deciding a case by assuming, arguendo, that an asserted constitutional right exists, and because I can understand, or at least am accustomed to, the reluctance of the present Court to admit publicly that Our Perfect Constitution[fn*] lets stand any injustice, much less the execution of an innocent man who has received, though to no avail, all the process that our society has traditionally deemed adequate. With any luck, we shall avoid ever having to face this embarrassing question again, since it is improbable that evidence of innocence as convincing as today’s opinion requires would fail to produce an executive pardon.
