The last paragraph mentions past convictions based on evidence where this sort of notice should have been given, but it wasn't policy to do so at the time. Is there a group out there known to deal with this sort of thing? Do the ALCU/AI/Supreme Court even have a chance before there's some retroactive fix? Also, based on their past decisions how would the SC rule?
