The decision to overturn the convictions of the B'ham Six, Guildford Four et al was not a declaration of their innocence, merely an admission by senior members of the judiciary that guilt could not be proved safely and within the requirements of the British criminal justice system. One does not equal the other, and whether they were guilty or innocent is a fact known, presumably, only by them and God.

What is absolutely certain, however, is the innocence of the the victims of those outrages who never got the chance to have reversed or mitigated the injustice which the bombers meted out on them.
