Yes (though frankly I think one could make the argument in every way: one could conceive of how/why a factually innocent person might either a) keep fighting to prove an injustice or b) just want to slide away into anonymity; and by the same token, one could conceive of how/why a factually guilty person might either a) keep fighting to prove an injustice or b) just want to slide away into anonymity.
I think the point here is that it's thoroughly bogus and biassed to claim that
"A normal person with a luckily commuted life sentence would just be happy at their good fortune and just get on with their life."
And on related matters, where does one start with the several flavours of wrong within this series of words:
"...he'd have to prove it was a wrongful conviction, as the ISC never said he was innocent"
Almost as *ahem*
wrong as claiming that a judicial fact established in a court process is an actual, immutable, irreversible, fact of truth
(On that last piece of wrong, the quickest and simplest way to show
quite how wrong is to consider any number of cases where a man - "Mr A" - has been convicted for a sole-attacker rape and murder of "Ms X" (which necessarily entails the finding of the "judicial fact" that the man raped and murdered Ms X), t
hen many years later DNA analysis reveals that the semen in/on Ms X actually belonged to a whole different man - "Mr B" - who was subsequently convicted of several other rape/murders, and who ultimately admitted to this particular rape/murder of Ms X. That "judicial fact" that Mr A raped and murdered Ms X doesn't look quite so immutable, irreversible and factually truthful now, does it.....?)
