I know a number of teachers, and there are quite strict mandatory reporting policies for when child abuse is even suspected.

The reality is that the organizations responsible for looking into these reports of abuse only have enough resources to investigate those where the child's life is in immediate danger.

The venn diagrams of "internet chat surveillance" and 'solutions to the problems of child abuse" are mutually exclusive.

Politicians are grossly morally corrupt to use child abuse as an argument against encryption when they're the ones controlling the purse strings for Child Services-type organizations. Feathering their own nests at the cost of actual, real progress on protecting children from abuse.
