Sex offending is abhorrent, as we all know. It is also pervasive. The figures that over the last 40 years have been gathered consistently show offending rates against girls under 16 at about the rate of one in four, and about one in eight to one in nine boys under the same age. Most of those people—and I think this is a really, really important thing to bear in mind—most of the offenders we are talking about, are well-known to those children. Often, they are within their own families, and often, as Mr O'Connor said at the beginning, they are repetitive offenders.
