When complaints were filed with the Diocese, the priest was quietly moved out of the Parish and nothing changed. Nothing bad ever happened to the priests who abused boys. The children went on to develop behavioural problems, drug problems, and other behaviours common to children who have suffered sexual trauma, and they are no longer "good witnesses" against their abusers.
The children never spoke of the abuse, and never got treatment for it either. But they suffered from the trauma for all of their lives. One such victim I know said that people call marijuana a "gateway drug". Trauma is the real gateway drug.
