No safety from legal lynching

More than half of the Australians now living have no personal memory of the Azaria Chamberlain case, now, after 32 years moving, one hopes into its epilogue. They were either not born, or too young. But they should know, if only for some healthy scepticism about Australian justice.

Azaria's mother, Lindy, and father, Michael, were convicted by the Australian criminal justice system, Lindy of murder and Michael of being an accessory after the fact - in effect found guilty of having helped Lindy conceal the death of the child and her involvement in killing it, after he discovered her involvement. The trial was apparently exemplary; long after a royal commission found himself unable to criticise the Crown Prosecutor, Ian Barker, QC, for overstating the evidence he had, or of concealing material pointing to their innocence. A full bench of the Federal Court had carefully considered the Crown case and refused to interfere with the verdict, even though the trial judge was privately expressing amazement at the verdict. The High Court refused to interfere with the decision, if on new and somewhat priggish grounds, that justice did not enter the matter if no error of law could be demonstrated. Beyond the trials had been two intensive inquests, and, between them, a forensic investigation, with top scientists from three continents, brought on by NT detectives smarting under criticism of the quality of their work by the first coroner, a former detective.

The case against them was circumstantial but impressive. The forensic evidence was particularly persuasive. The jury was convinced beyond any reasonable doubt that Lindy had sat in the front seat of her car with a pair of scissors, stabbed the child, held it until it died, then concealed it, probably in the boot of the car while setting off a hue and cry about a dingo in the family tent at an Ayers Rock camping ground.

No one has ever suggested that a police or forensic witness gave consciously false evidence. All were honest and decent people, even if some were not as clever and experienced as they thought they were. Lindy Chamberlain was not ''verballed,'' nor was evidence implicating her ''planted''. It is important to remember that the law - judges and lawyers - failed Lindy as badly as the police and scientists.

The essential trouble was that both the investigating police, and the principal scientific witnesses were victims of what some called theory-dependence. They believed - in some cases just ''knew'' in their gut - that the Chamberlains were guilty and the dingo story cock and bull. They looked for evidence that tended to confirm their theories, and tended to ignore or explain away evidence which did not.

The biggest shocker, as it turned out, was a forensic biologist, Joy Kuhl, who, testing the Chamberlain car thought she had detected foetal haemoglobin in stains on the front wall of the front passenger side. If Azaria had been murdered in the front of the car, these ''bloodstains'' were just where one might have expected them to be. On her evidence, as well as an assertion by a scientist that tears on the baby's jumper were scissor cuts, not bite marks, Lindy was convicted.

What Joy Kuhl ignored was that the chemical test she had used to detect foetal haemoglobin levels also detected the presence of iron. There was no blood on the car's panels, but lots of paint, dust and ore. Painstaking examination of Kuhl's findings found a repeated tendency to overconfidently report evidence seeming to implicate Lindy, and a tendency to discount material which did not. She had ceased to be an objective expert, and became an advocate for a theory we now know positively to be quite wrong.

Could it happen today? Of course. Some might think that major advances in forensic science - and in the professionalism of police investigators and forensic scientists would now prevent such mistakes. Some might think modern science - say of DNA - is fairly settled, with jurors able to be told, for example, that the chance of a person's having the same DNA by coincidence is one in, say, 80 billion.

What jurors are, however, only rarely told is that the sloppiness of many murder investigations is such that the risk of cross contamination of evidence samples taken from scenes of crime may be as high, on average, as one in 50, that is, a very real possibility.

When such ''evidence'' leads investigators away from an initially open mind to a strong theory of a particular person's guilt, the blindness can be almost comical, if it was not for the disastrous consequences. We have in recent times seen a number of Western Australian convictions overturned, not on the basis of the emergence of significant doubts, but the discovery of evidence which proved the defendant innocent. In some cases, there was confessional material - or at least words spoken which police interpreted as, and urged upon jurors, as admissions. Often, as with Chamberlain, and significant miscarriages in Queensland, WA and NSW, the cases had been repeatedly before the courts, convictions being rubber stamped by judges seemingly unable to imagine that police, or experts, could get it all wrong.

A new technical book, Crucial errors in murder investigations, by Ted Duhs of Bond University, shows how investigators can make honest, but fatal, mistakes. His cases are investigations mucked up by Queensland detectives, although there is cross reference to famous disasters elsewhere, including to the Chamberlain case. (Professor Barry Boettcher, who exposed a good many of the fundamental scientific errors of the Chamberlain case, has written a foreword.)

Most stem from the human error of theory-dependence - focusing on evidence that supports a theory already formed, ignoring evidence that doesn't, making connections that send investigations down certain paths, holding on to theories even after they have been falsified. Duhs shows in case after case how this caused vital clues to be ignored, and investigations marshalled to prove things which were wrong. Triumphant detectives are rarely given to self-doubt.

It should not be thought that concerns about miscarriages of justice come only from an anti-police brigade. Here in Australia a number of forensic scientists have expressed concerns about the quality of evidence sometimes going before courts, the use of bad procedures, failures of chains of custody, incapacity to replicate results, the use of samples too small to guarantee results, sloppy systems of avoiding contamination and cross contamination, the use of impure chemicals, and the use of equipment which had not been validated or which were known for inaccurate results. As problematic, in some jurisdictions has been an association so close between forensic scientist and investigating police, as well as a pressure of overwork, that presents real risks of undermining the detachment that experts pretend. The scientific method, of course, is ever anxious to test a theory, not least with evidence that challenges it, rather than focusing only whittling facts until they fit the theory. The Chamberlain case is a warning about legal lynchings, and a reminder never to think a case is closed.

    • A thpughtful piece Jack. However you have glossed over one critical element in the mob mentality that led to one of Australia's worst miscarriages of justice - the media. As a working journalist in a daily newspaper throughout the legal processes that followed I can well remember my editor and many others, including TV news directors showing contempt for the dingo theory and this bias shaped the way the whole matter was reported. Interestingly though most reporters who actually sat in the courtrooms throughout the legal proceedings would not have convicted Lindy Chamberlain in the first place. When any sector of society gets it into their head that they know what is the "truth"and has the ability to assertt that "truth" widely there is the potential for a miscarriage of justice in the broadest sense. The same mistakes have been made by the collective media many times sinse the Azaria Chamberlain saga and indeed one could argue are currently being committed in the constant talking down of the Australian econmomy, which by every international indicator available is doing better than almost every country in the world. However, try telling that to the average nes consumer.

      • Yes, I agree about that. There was a strong sexist aspect of that too, given that Lindy was an attractive woman.

        But while there was a great deal of folk legend and populist nonsense in the whole story, one of the things which fed the story, and kept it on the front pages for years, was the complete conviction of the police and prosecution (and behind them the Everingham Government of the NT) that they had it right, and that Lindy was a monster (albeit a very clever one). That, fed back via journalists, and not only tabloid ones, inspired a good deal of journalistic risk taking, not to mention shameful and unjustifiable journalistic technique.

        In time that produced its own counter-effect, of people not only convinced of her innocence, but moved to push and promote her case. I doubt that the Chamberlains by themselves would have had the resources to mount the sort of investigations or causes mounted by people such as Barry Boettcher, Ken Crispin and many others. I cannot think of a case that fuelled so many dinner table arguments. But likewise which fuelled so much concern about the justice system.

    • You only have to look at the Judith Kirchener case in Italy just a few years ago. To see how inept some forensic and police work can be.

      • Very good article and some very interesting comments, particularly regarding the media. Perhaps there should be a new series - "CSI Australia - The Stuff Ups".

        • Well look at this year alone with our woeful media.

          Craig Thomson hounded to the point he asked if they wanted him to kill himself - the case against Craig Thomson is based on a rejected credit slip in the name of ThomPson from 2005 and another case of using prostitutes originally credited to Jeff Jackson and changed by Kathy Jackson. Craig was in the Margaret River Valley with his wife.

          Meanwhile Independent Australia have dozens of documents on line proving that Kathy Jackson has been treating herself to $84,000 volvos, a Merc, charged down as legal fees in Hong Kong, hundreds of thousands in unknown consulting fees, tens of thousands in honorariums for what no-one knows and so on.

          Peter Slipper was set up by James Ashby with the assistance of Chris Pyne, Mal Brough and other liberal party hacks - yet Ashby withdrew almost all the supposed claims but it is Slipper portrayed daily as some beast. The first sex case with no sex.

          Mention sex in this puerile country and the media go into a mad frenzy.

          Like with refugees - another editorial in the Australian today demanding we break 60 year old laws and treaties but no reason ever given why 24 refugees a day is a threat.

          And as my letter in this paper today shows, even former refugees think today's refugees are not worthy of help yet they all have faced a good deal worse for a good deal longer than those in WW11 - the Afghans have had 5.5 times longer than WW11 of suffering and invasions - I would suggest they be silent.

          Australia hardly has a media now, just shock jocks and spivs with few exceptions, present company being an exception of course.

          Thanks Jack, yesterday the Adelaide Advertiser used it's entire letters page allowing cretins to pretend I am wrong about the refugee laws, even one nutty doctor in London.

          I am too old for the niceties these days.

          And today Michael Gordon has the consequences of lazy journos. like Sarah Ferguson using vengeful spies to set up innocent people.

          A young Afghan man has a request to help the brother he believed was dead and is branded a smuggler.

          And Sue Spencer still defends the ridiculous program.

          Wrong headed stories have consequences as they have had for the Chamberlains for 32 years.

          Many heads should be bowed in shame today but they will be out looking for more bogus hookers instead or some other sucker to set up with something.

          • Nice article: gets to the pointand disposes of the red herrings into the rubbish bin of history, as usual, in the minimum number of paragraphs - thanks Jack.

            • People love to join mobs and lynch someone.
              .
              Persuade a mob to start lynching and that mob will gain cohesion and gain respect for the person giving them license to hold kill-parties. This technique has been used by tyrants throughout history to control people.
              .
              We frequently see this in modern society, with leaders encouraging "hate-fests" against vulnerable people in society. First, label people, and pretend a group is homogeneous. Next, find a few examples of bad behaviour and pretend that behaviour is typical of everyone in the group. Then find a way to punish the whole group by treating them with hatred, contempt and penalising them financially. - I'm sure it's all written up in a textbook for tyrants and coat-tailers somewhere.
              .
              Until we progress past this humanity will never be civilised.
