“Allegations of multi-perpetrator and multi-victim sexual abuse emerged to public awareness in the early 1980s contemporaneously with the denials of the accused and their supporters. Multi-perpetrator sexual offences are typically more sadistic than solo offences and organised sexual abuse is no exception. Adults and children with histories of organised abuse have described lives marked by torturous and sometimes ritualistic sexual abuse arranged by family members and other care-givers and authority figures. It is widely acknowledged, at least in theory, that sexual abuse can take severe forms, but when disclosures of such abuse occur, they are routinely subject to contestation and challenge. People accused of organised, sadistic or ritualistic abuse have protested that their accusers are liars and fantasists, or else innocents led astray by overly zealous investigators. This was an argument that many journalists and academics have found more convincing than the testimony of alleged victims.”
