It’s actually not complicated.
A retired Australian judge has just issued an opinion on David Bain’s guilt or innocence without the benefit of an actual trial. This makes his opinion about Bain’s innocence no more relevant than you and I.
And whatever else you and I might think about it (and your opinion may well be the same as mine), NZ’s legal system as it’s properly constituted (i.e., without backdoor reports by carefully-selected judges) belatedly found him not guilty of the crime, and therefore locked up wrongly.
And because he was locked up wrongly, he naturally does deserve compensation from the justice system for the injustice.
That is only justice.
So either pay him compensation, Minister, or say out loud that you think the justice system is flawed.
I dare you.
(In other words, my opinion hasn’t changed one bit since this time last year.)
