I am all ears.
Are you saying that the Catholic church has not tried to cover this stuff up in the past or are you saying they have just started to do so?
I was in news reporting at the time. Fresh from journalism school, we were taught to notice what was left on the cutting room floor. Here are just a few things. First. child molesters were equally distributed all throughout society--doctors, churches, synagogues, sports, clubs, and schools--with perhaps schools being the worse. The Catholic Church was below the national average in such things. Second, psychiatrists recommended that molesting priests go through their programs and then be reassigned to a different parish. Third, priests and bishops were beginning to tell the psychiatrists that their programs and recommendations did not work, did not work, did not work. At this time the news media decided to break the child molestation problem all throughout society--but to only focus on the Catholic Church.
As a Catholic, I am glad they did because the Catholic Church (in the US) became the model on how to change and set up new protections for children. Many of us in the Church were a part of that. We might have the lowest percentage of molesters, but we wanted the numbers to be ZERO. This all came about in the 80s. Forty years later non-Catholics (and even lapsed Catholics) still think we are back in the 1950s-1970s. We're not. In the United States the United States Conference of Bishops and the parishioners have been working for forty years to insure things that happened fifty years ago do not happen again.
Interesting, isn't it, that if you were molested by a priest fifty years ago, there is a link for you. If you were one of the more likely to have been molested by a family member (greatest likelihood for molestation) or a school employee (schools having one of the worst percentages) too bad. Your family and the tax payers of school districts can't afford such suits.
Is the Catholic Church perfect? No. But we do not have to look far to find agencies (news media included) who have even worse failures. And unlike some of these others, the Church is still striving for perfection.
