During the early 1980s, some courts attempted "ad hoc" accommodations to address the anxieties of child witnesses in relation to testifying before defendants. Screens or CCTV technology are a common feature of child sexual assault trials today; children in the early 1980s were typically forced into direct visual contact with the accused abuser while in court. SRA allegations in the courts catalyzed a broad agenda of research into the nature of children's testimony and the reliability of their oral evidence in court. Ultimately in SRA cases, the coercive techniques used by believing district attorneys, therapists and police officers were critical in establishing, and often resolving, SRA cases. In courts, when juries were able to see recordings or transcripts of interviews with children, the alleged abusers were acquitted. The reaction by successful prosecutors, spread throughout conventions and conferences on SRA, was to destroy, or fail to take notes of the interviews in the first place. One group of researchers concluded that children usually lack the sufficient amount of "explicit knowledge" of satanic ritual abuse to fabricate all of the details of an SRA claim on their own. However, the same researchers also concluded that children usually have the sufficient amount of general knowledge of "violence and the occult" to "serve as a starting point from which ritual claims could develop."
