What can be done is simple: Tear into ever diocese in the US and turn out ever predator there is - systematically and without emotion.
This is just a single diocese. Others are either in great shape, equally as bad, or worse. To move on, the state of each diocese must be known and steps must be taken, either to learn from the good ones and put into practice their experience, or to clean up the bad ones.
Better question, what about the Cardinals? The Pope? How far up does this go?
I converted through RCIA at St. Ann Parish in Coppell during that time. Back then, St. Ann was a growing parish of about 1000 families. It was launched by Msgr. Killian Broderick about ten years before that, with about 400 families.
There were no grey areas with Msgr. Broderick, and he would occasionally speak truth to power in his homilies. It wasn't until after his death that I read of the true story behind the friction between our parish and the diocese.
Killian testified for the plaintiffs in the Kos trial. Kos had sought out his guidance outside the confessional, and Killian felt honor bound to testify, which must have infuriated Bishop Grahmann. The lingering hostility delayed breaking ground on our new church by at least five years.
The results of Msgr. Broderick's leadership are self-evident: St. Ann Parish is now the 6th largest parish in the United States, with about 8000 families registered.
Our "two adult" policy is strictly enforced, i.e. two adults must be present whenever children are present. Seems simple, but it's very effective.
There was one night when I was teaching last year when I was the only one of six teachers present that night. We solved that by combining both classes, bringing in one of the staff to assist me. It was a special night for me, as the lesson for the night was "agape love". I departed from the curriculum, and used a section of Fr. Robert Spitzer's book "Healing the Culture".
I must have appeared to be really fired up that night, 30+ 6 graders were quiet for over 30 minutes, and their questions demonstrated that they were interested in the topic, and paying close attention.
It was nothing like Fr. Spitzer's presentations, who appears regularly on EWTN. I know him well: he graduated two years ahead of me at Gonzaga, and served as President of GU during the early 2000s. His leadership helped to launch a rebirth at Gonzaga, aided by the success of our basketball team. Over the past 20 years, enrollment has grown from 2000 undergrads to nearly 6000.
