Kenneth Lanning, an FBI expert in the investigation of child sexual abuse, has stated that pseudo-Satanism may exist but there is "little or no evidence for ... large-scale baby breeding, human sacrifice, and organized satanic conspiracies." There are many possible alternative answers to the question of why victims are alleging things that don't seem to be true. ... I believe that there is a middle ground—a continuum of possible activity. Some of what the victims allege may be true and accurate, some may be misperceived or distorted, some may be screened or symbolic, and some may be "contaminated" or false. The problem and challenge, especially for law enforcement, is to determine which is which. This can only be done through active investigation. I believe that the majority of victims alleging "ritual" abuse are in fact victims of some form of abuse or trauma.
