'Please, if there is any way you could help with our situation, by yourself or anyone you know, could you please get in touch. We can honestly say, hand on heart, we haven't done anything to hurt our baby. We are now been [sic] assessed and we got told [sic] that when we go to the finding of facts hearing and we still insist we haven't done anything, our twins will go up for adoption.'Letter from parent
'For me, the unusual feature is death so soon after being seen well, the fact that there have been previous deaths in the family and the fact that he had had an episode of some sort only nine days before he died that caused him to be assessed in hospital, because those features are ones that are found really quite commonly in children who have been smothered by their mothers. So the diagnosis for me, the clinical diagnosis, would be this was characteristic of smothering.'Testimony of Professor Sir Roy Meadow, R v Cannings, March 2002
The authority of medicine derives from its science base, so it would be reasonable to assume that doctors when called on to give their expert opinion in court would have a thorough balanced grasp of the relevant scientific evidence. The successful appeals of Sally Clark and Angela Cannings against their convictions for child murder would suggest otherwise, as does the recent ruling of the Attorney General that a further twenty-eight cases of parents convicted of smothering or shaking their children are 'potentially unsafe'.1 Nor can that be all, for the Attorney General's review was restricted to the Criminal Courts and thus does not take into account the several hundred cases a year heard in the Family Courts whose less stringent standards of proof ('balance of probability' rather than 'beyond reasonable doubt') would further increase the risk of unsafe convictions. Thus the medical advocacy of contentious theories of the mechanisms of child abuse is likely to have been responsible for a systematic miscarriage of justice on a scale without precedent in British legal historywith devastating consequences for the parents wrongly convicted. Here I offer a 'master theory' to explain how this extraordinary situation has come about.
| THE HIDDEN EPIDEMIC OF CHILD ABUSE |

Doctors are no different from anyone else in being reluctant to admit they 'do not know'. Why, for example, might SIDS affect two or more children in the same family, or how might a seemingly trivial accident cause an acute intracranial injury? Some might thus be unduly susceptible to the notion that the uncertainties arise not from their lack of knowledge or clinical skills but from parental concealmentthat each of these ambiguous clinical situations is potentially a form of hidden or covert abuse inflicted by parents in such a way as to hide their intentions from external scrutiny. Further, these clinically ambiguous situations are not uncommon, which would suggest that child abuse is both more prevalent than is widely appreciated and perpetrated by even the most apparently respectable of parents. Paediatricians clearly have a major responsibility in identifying these concealed forms of abuse if they are to protect children from further injury or death.

The implications of Munchausen's syndrome by proxy were twofold: it alerted doctors to the possibility of fabricated illness as a potential differential diagnosis in children with unexplained symptoms. But it also demonstrated how the seemingly most devoted of parents might, in reality, be potential child abusers. Meadow himself, commenting on the mothers in the cases he described, observed how they were 'very pleasant to deal with, cooperative and appreciative of good medical care.'
David Southall's innovative technique of covert videosurveillance for investigating apnoeic episodes in children vividly confirmed the sinister reality of hidden abuse.5,6 Now paediatricians attending meetings and conferences could see for themselves the blurry black and white images of mothers caught in the act of smothering or choking their babies. Southall's study widened the spectrum of child abuse in two significant directions. It offered, in smothering, a plausible explanation for why a child might experience recurrent acute life-threatening events necessitating urgent admission to hospital. And it emphasized, once again, the possibility that some at least of those children whose deaths were labelled as SIDS might have been the victims of smothering. Southall in a further report of thirty children undergoing covert videosurveillance identified twelve siblings who had died unexpectedly, eight of whom the parents subsequently confessed to having smothered. Thus parental smothering must be a clear possibility in any child with recurrent acute life-threatening events where there has been more than one unexplained childhood death in the family.7

Significantly there were certain similarities in the signs and symptoms of children with these clinically ambiguous situations and those recorded in well authenticated forms of abuse such as smothering, poisoning and abusive head injury. Thus it seemed reasonable to infer, by extrapolation, that these presentations were 'characteristic' of covert forms of abuse which could then be confidently diagnosedeven in the absence of any other circumstantial evidence such as bruises, signs of neglect or parental history of violence. During the 1980s the trio of clinically ambiguous situations would become redesignated as 'child abuse syndromes'. A key influence was 'Meadow's rule' regarding SIDS. While the absence of reliable pathological findings made it difficult to distinguish SIDS from smothering, Meadow argued that two or more childhood deaths in the same family, along with a recognizable 'pattern' of events (such as previous acute life-threatening episodes) was strongly suggestive of infanticide: 'two is suspicious and three murder unless proved otherwise...'.9-11 Another was the proposal that two specific presentations of childhood injury were 'characteristic' of abusive assault. Caffey's original description of shaken baby syndrome suggested that the whiplash effect of vigorous shaking offered a 'reasonable explanation' for the presence of subdural and retinal haemorrhages in severely abused children.12 The imagery of how the violent to-and-fro movement of the baby's head could cause bleeding of the vessels of the eye and brain proved very persuasive and it seemed logical to infer that any child presenting with retinal and subdural haemorrhages must have been shakendespite the absence of other circumstantial evidence of abuse.13-15 Similarly, Caffey attributed a radiological 'bucket handle' appearance of the metaphyses of the long bones in severely abused children as being due to a 'twisting and wrenching' of the child's limbs by the parents.16 Subsequently, it was suggested that those children in whom abuse was suspected should have a skeletal survey for similar 'suspicious' metaphyseal lesions that were interpreted as being characteristic of abusive assaultagain, despite the absence of clinical signs of fracture or subsequent radiological evidence of healing.17,18 A third was a widened case definition for Munchausen's syndrome by proxy. Meadow, in his initial series, had confirmed the diagnosis either by covert surveillance or by confronting the perpetrator and obtaining a confession. In a widened definition the presence of 'diagnostic pointers' was proposed for use in children with medically unexplained symptoms. They included:

Nonetheless, the facility with which the syndromes could bring to light covert abuse concealed from view their poor evidential basis. The causal link between the putative mechanism of assault and subsequent injury could be neither independently confirmed nor experimentally investigated. It might seem reasonable to extrapolate from the presence of retinal and subdural haemorrhages in the battered child that these features had the same significance in a child with no other circumstantial evidence of injury. Certainly the powerful imagery of violent shearing forces disrupting the blood vessels was persuasive, but shaking has never been directly observed or proven to cause such injuries; the supposition that they do is based on (contested) theories of biomechanics.24
Rather, the legitimacy of the syndromes was predicted on two related and highly improbable assumptions, scientific and legal. The scientific assumption was that there could be no other explanation, either known or that might be discovered at some time in the future, that might explain these 'characteristic' presentations. Meadow's 'rule', for example, precluded the possibility that there might be some unknown genetic explanation for multiple unexpected childhood deaths in the same family, while the 'characteristic' pattern of shaken baby syndrome precluded the possibility of some alternative explanation for the retinal and subdural haemorrhagessuch as an acute increase in retinal venous pressure from intracranial bleeding caused by accidental head injury.25 The legal assumption presupposed that these presentations were so specific for abuse that they were by themselves sufficient to secure a convictioneven in the absence of the sort of circumstantial evidence of violence or neglect that would normally be required to return a guilty verdict in a court of law.
Put another way, the 'characteristic' presentations of the syndromes could not sustain the interpretation placed upon them: they might be 'consistent with' but could not, by themselves, be 'diagnostic of' child abuse. Thus some at least of the parents contributing to the statistics of the fourfold rise in child abuse were likely to be innocent. Three additional factors, in particular, bolstered the credibility of the syndromes in the Family and Criminal Courts.
The authority of the child abuse expert
By the close of the 1980s, the leading experts in child abuse had acquired
an international reputation and were thus called on to instruct and educate
not just their fellow paediatricians but also the police, lawyers, social
workers and judges in the child abuse syndromes. Their persuasive expert
opinion, when expressed in court, was guaranteed a sympathetic hearing, while
their confidence in the syndromes they had discovered was virtually
unchallengeable. Further, they could scarcely accept the force of contrary
evidence since to do so would require them to concede that their expert
testimonies might, in similar cases, have resulted in wrongful conviction.
Meanwhile the costs of the process of investigating allegations arising out of
the child abuse syndromes rose to an estimated £1 billion per year, with
the more prominent experts receiving fees for the preparation of their reports
and appearances in court in excess of £100 000 a
year.26
The circular argument of successful convictions
The validity of the child abuse syndromes would appear to be confirmed by
the high proportion of successful convictions that followed the courts'
careful scrutiny of the allegations against parents. These convictions,
however, came to rely increasingly on a circular argumentwhereby the
main evidence for the child abuse syndrome of which the parents were accused
was that parents had been convicted of it in the past. Thus parents whose
child presents with subdural and retinal haemorrhages are accused of
inflicting shaken baby syndrome because, in the vast majority of cases,
parents of children with subdural and retinal haemorrhages are convicted of
causing shaken baby
syndrome.27
Similarly, Meadow argued that 'the likelihood that the court verdicts
about parental responsibility for [causing their children's death] were
correct was very high indeed', without making clear that it was his
expert testimony that repetitive SIDS was 'murder unless proved
otherwise' that had been a major factor in securing those
convictions.10
There is a further element of circularity in the presumed pathogenesis of the syndrome of which the parents are accused. The theory of shaken baby syndrome presupposes that violent, abusive force (comparable, it is claimed, to that sustained in a high-speed road traffic accident or a fall from a second storey window) is necessary to cause retinal and subdural haemorrhages. The parents are then caught in the catch-22 of either confessing to the alleged assault (for which they might be offered the inducement 'if you say you did it we will let you have your child back') or denying it, in which case their denial is evidence they must be lying about the events surrounding their child's injury, which is then further evidence of their guilt.28
The silencing of parents
The forces of expertise ranged against the parents were formidable enough,
but it is apparent too from their personal accounts that they were subjected
to a series of intimidatory tactics to silence their protestations of
innocence and deny the validity of their testimony as the only witnesses of
the circumstances surrounding their child's injury or
death.29,30
Thus parents describe how, when summoned to see the consultant to learn (they
presume) about their child's progress, they were 'ambushed'
with the diagnosis of, for example, shaken baby syndrome, presented to them as
irrefutable fact ('your son must have been violently shaken for several
minutes to cause these injuries') without any suggestion that there could
be some alternative explanation.
The prompt involvement of the police and social workers would lead to further accusatory interrogations that begin from the principle that the parents must be guiltyas the doctors would not have made such serious accusations if they were not convinced they were true. The transcript of these interrogations would subsequently be turned against them in court so that any inconsistencies in their explanations of how their child's injuries might have occurred were then presented as evidence of their efforts to conceal their guilt.31 Parents describe the same pattern of events where they would only be informed late on a Friday evening that a preliminary court hearing had been arranged for the following Monday morningthus leaving them the weekend to find a lawyer (who was unlikely to have any expertise in this field) to contest their child being taken into foster care.32
These psychological tactics were a prelude to the yet more powerful intimidatory weapon of technical obscurantismthe description of their child's injuries and couching of the charges against them in a language in which the professionals were fluent but the bewildered parents were not. How could they hope to dispute the allegations when they did not know what was being talked about? Parents are of course entitled to seek their own expert opinion, but soon discovered that the overwhelming consensus about the validity of the child abuse syndromes meant it was very difficult to find anyone to argue in their defence; or worse, the expert reports they requested were actively detrimental to their case.33
This silencing of parents was made more effective still by the rules of confidentiality that wrap the proceedings of the Family Courts in a cocoon of secrecy, making parents liable to a charge of contempt of court if they sought advice or support from anyone not directly involved in their case. This secrecy in turn protected the proceedings of the court, and in particular the testimony of expert witnesses, from external scrutiny while concealing from public view the spectacle of so many apparently respectable parents being convicted of inflicting these terrible injuries on their childrenwithout any circumstantial evidence that they had done so.

Similarly, further research has undermined the validity of retinal and subdural haemorrhages as being characteristic of shaken baby syndrome, with an evidence-based review finding 'serious data gaps, flaws of logic and inconsistency of case definition' in the relevant scientific work.41 Shaken baby syndrome was not, as its name implied, a 'syndrome' but rather encompassed several different forms of brain injury, with different clinical history and neuropathology, involving some mechanism other than shaking to account for the presence of retinal haemorrhages.42,43 Thus a series of independently witnessed accidents confirmed that, as parents had maintained, minor falls could cause an acute subdural bleed with the retinal haemorrhages being due to a sudden rise in retinal venous pressure.44 Further, parental histories of a preceding episode of respiratory collapse were compatible with the very different pathological findings of anoxic brain damage, with disturbance of the microcirculation causing thin subdural and retinal haemorrhages.45,46
Meanwhile, the widened definition of Munchausen's syndrome by proxy based on 'diagnostic pointers' has also resulted in wrongful convictions, with the child's unexplained symptoms proving to be due to some rare or unusual medical condition with which the doctor was not familiar.47 Subsequently the syndrome would be renamed 'factitious illness' in recognition of the fact that, while some parents may fabricate the symptoms of their child's illness, the combination of unexplained symptoms and the mother's personality profile did not constitute a syndrome of abuse.48,49 Finally, radiologists' misinterpretation of normal variants of ossification in the first year of life as being metaphyseal fractures accounts for the obvious discrepancy between the findings of multiple fractures on skeletal survey and the absence of any clinical signs of abusive injury.50
This serial collapse of the improbable scientific assumption that there could be no explanation other than abuse for the characteristic presentation of these syndromes has exposed in turn the equally improbable legal assumption that, contrary to sound judicial practice, it is possible to convict parents without there being additional circumstantial evidence or reasonable motive for their abusive intentions. Thus Justice Judge would, in his exoneration of Angela Cannings, draw attention to 'the absence of the slightest evidence of physical interference which might support the allegation she had deliberately harmed them'. And, again, he emphasized how 'the absence of any indication of ill temper or ill treatment of any child at any time' and 'the evidence of both her family and outsiders about the love and care she bestowed on her children' made it extraordinarily unlikely that she might have smothered them.
| CONCLUSION |
|---|
|
|
|---|
Meadow and the proponents of the child abuse syndromes necessarily take the contrary view, and in so doing are required to portray parents' protestations of innocence as deceitful. That moral judgment, together with the failure to recognize that medical knowledge may be incomplete, meant that Angela Cannings' wrongful conviction for infanticide was almost inevitable.53 The question remains how many other parents have similarly been wrongly convicted of the terrible crime of injuring their children, and been robbed of their families, livelihoods and good name.
