 The "reasonableness" standard operates within the Sixth Amendment constraint, not as a substitute for it.It was up to California to tailor its sentencing scheme to conform with the Court's decision, just as other states had conformed their sentencing schemes to conform with "Apprendi" and "Blakely".Some states allow the jury to make the necessary findings during trial; others do so in a post-trial sentencing hearing; still others "have chosen to permit judges genuinely to exercise broad discretion within a statutory range, which, everyone agrees, encounters no Sixth Amendment shoal."
