My take, for what it is worth, is that it is important for the general public to know that criminal activity in which children are compromised or harmed is properly investigated and that any offenders are dealt with, that those directly affected are suitably involved and that there are arrangements to deal with any reasonable concerns expressed by members of the public.
However, I can't see that there is any benefit at all in sensationalist voyeurism. I think that type of coverage, in such circumstances, cheapens all of us and achieves nothing.
