In one analysis of 36 court cases involving sexual abuse of children within rituals, only one quarter resulted in convictions, all of which had little to do with ritual sex abuse. In a 1994 survey of more than 11,000 psychiatric and police workers throughout the US, conducted for the National Center on Child Abuse and Neglect, researchers investigated approximately 12,000 accusations of group cult sexual abuse based on satanic ritual. The survey found no substantiated reports of well-organized satanic rings of people who sexually abuse children, but did find incidents in which the ritualistic aspects were secondary to the abuse and were used to intimidate victims. Victor reviewed 21 court cases alleging SRA between 1983 and 1987 in which no prosecutions were obtained for ritual abuse.
