There is no basis in text, tradition, or even in contemporary practice (if that were enough), for finding in the Constitution a right to demand judicial consideration of newly discovered evidence of innocence brought forward after conviction. My concern is that in making life easier for ourselves we not appear to make it harder for the lower federal courts, imposing upon them the burden of regularly analyzing newly-discovered-evidence-of-innocence claims in capital cases (in which event such federal claims, it can confidently be predicted, will become routine and even repetitive).
The virtue of a democratic system with a [constitutionally guaranteed right to free speech] is that it readily enables the people, over time, to be persuaded that what they took for granted is not so, and to change their laws accordingly.
