Mr. Geoff Knupfer:

There was a statement in the early days, in 1999, where I believe nine cases were reported. That has grown over the years and a further two cases were added to the list at various times. That initial information has been enhanced or improved as the years have gone by. It is really difficult to talk about this sort of detail, both because we are not allowed to and because I do not want to implicate anyone. Much of the work has gone on through intermediaries who, on a few occasions, have provided direct contact with primary sources, that is, people who were involved in these events. Often, however, information is passed anonymously and we do not know who these people are. That is the frustration.
