Does the Commissioner of Police condone Miscarriages of Justice?

Another interesting aspect here of the similarity and dis-similarity of how police administration deal with Miscarriages of Justice. As the link above shows a profiler is warned, properly it would appears by selective use of conditions placed on his past employment, for speaking out on his concerns at the lack of safety of the conviction for murder of Teina Pora. He cites his conclusion that the killer of Susan Burdett was Rewa, the convicted 'lone wolf' rapist whose dna was found at the scene of Susan's death. As an ex police officer, and current civilian police employee, he was told to, well, effectively shut up, on the subject of his belief that Teina Pora is an innocent man in prison, convicted of the crime that all logic provides was committed by the hunting rapist Malcolm Rewa.

Contrast this 'speaking out' warning compared to the case of David Bain, a man once found guilty of five murders, freed on bail as the result of a finding of an 'actual' Miscarriage of Justice and then found not guilty at a retrial. Later, as is to be considered in the High Court later this year, found to be innocent on the balance of probabilities of the crimes of which he was once falsely accused. In the Bain case there has been a running commentary for over 3 years of 'evidence' and 'opinion's of ex police and current police officers. By in large these have all come from hate-siters. 'People' who have bragged on line about who they have contacted, ex Detective Weir for example, and report what they claim they were told. On every occasion what was 'claimed' and recorded as having been said was information that pointed, falsely, to David's guilt. There has been one particular hate-site administrator who has been 'divulging' on line 'conversations had with ex and current police and other witnesses as 'he' goes about reconstructing a case against David, a case at odds with both the truth and facts.

So just to be clear, in the Pora case ex police are warned to silence for speaking out about their concerns as to the obvious innocence of Teina. While conversely, alleged 'leaks' from police or ex police against David are allowed by the police hierarchy to go unanswered. It's a clear demonstration that the Police Commissioner's office objects to opinion that Pora is guilty but has none what so ever in it's campaign to continue to 'prove' that Bain is guilty. Fair and measured, equitable even? Don't think so.
