Surely the best way to combat this is to ensure more people know the signs of child abuse and know how and where to report it., the people who they report it to ACT and we can protect more children and young people that way.
It is not a nice subject but here in the UK safeguarding training is compulsory for school staff, there is a legal duty.
Plus there has to be information sharing among police forces, hence we have UK disclosure and barring service so there is a single point of information on people who are barred from working with children.
People need to know that their concerns will be acted on, as that one small thing is part of a wider picture of the child.
