The moral panic about ritual/satanic/sadistic abuse in Rochdale occurred when I was a rookie probation officer, and we were all sent to conferences to look at how this had arisen and what facts/evidence were known. It seems stories were circulated on one very large well known housing estate with a high level of deprivation. Misinformation and malicious behaviour, such as telling the authorities that a family whose children were already in care, had buried children's bodies in the garden, were investigated and rumours spread like wildfire when the garden was dug up and bones were found - as it turns out, a family pet of previous tenants. The hostile relationship between tenants and the authorities worsened, every case of child protection was looked at with suspicion by the residents, and children were kept in care for their safety when neighbour rounded on neighbour. Families were moved and some correctly reunited with their children after undergoing procedures to ensure the children were less likely to be at risk of neglect or abuse.
As usual, the papers had a field day. So many residents wanted to give stories to the gutter press. The authorities could not give confidental information, such as the facts about sex offenders saying their children had been wrongly taken away when they were being routinely abused. There were nuggets of truth in the middle of this mess. Children did need protection, some had been threatened with satanic abuse in the same way that parents would threaten police and prison, children in care did need to be with foster parents and were not returned to parents afterwards, as decided by family court judges with the help of professional assessments.
There have been a few cases of ritual abuse known here and in the USA, very few. Interestingly, those Rochdale children will now be adults. They have not come forward to say they were unfairly placed with foster parents.
