The pardon is important because it is always good when it is officially acknowledged that the so-called golden ages, which are claimed to have existed by right-wing idiots, were no such things and were actually a time when the state hung the innocent and were benighted enough to believe that it was ethical to turn a bloke into women (Turin grew breasts due to his treatment) in some hypocritical belief that the sort homosexual gropings which most of the establishment had witnessed, endured, inflicted or enjoyed at school (beastliness), was more damaging to consenting adults than it was to children, and while they allowed the beatings and buggery to continue unabated in the public schools, they chose to make a public example of a war hero to underpin their vile hypocrisy.
The pardon is slightly regrettable too because Turin's case was always the perfect example of how the state exploits people for its own purposes and when that purpose has been served, betrays them.
This is still going on, as every soldier will know. Cut their compensation, deny them support, while hiding behind cheap sentiment and pageantry, which serves the state far more than those sacrificed or damaged.
Pardoning Turin does not change that horrible fact and only fools the present generation into believing the establishment is not as vile and hypocritical as it actually is.
