Again, this was the coverup.
With regard to the comparisons between the rate of sex crimes of Catholic schools and public schools, your data underlines the superiority of the climate and standards created in Catholic schools. This should be underscored in the Catholic Church's PR.
If the MSM was fair, it would also be illuminated in the MSM. But it has had, as its mission, the denigration of Catholics.
For some reason --- and I really don't understand way ---much child abuse comes to light only years or decades after the offense, when the now-adult victim seeks redress.
It might be that the child victim is either deeply confused or deeply frightened, or tells his story in some uncertain terms and is not believed; or it might be that the adult realizes that his ongoing emotional problems stem from his early experience of abuse; or it might be the publicity of widescale prosecutions (and multi-million-dollar settlements) that causes people to, at last, remember past offenses.
An ugly business altogether.
Let those who know more about it, chime in here.
