It remains deeply discomforting to think that child abusers are like us, are related to us and in many aspects of life appear to be decent people.
By 1984 there was increasing evidence that child sexual abuse was a major issue in Ireland.
Others have been contacted by strangers over the internet and asked to engage in sexual acts on camera.
This means trying to see beyond our disgust at such crimes against children and to understand the factors that lead a person to commit them.
