Who indeed? This was generally not a public phenomenon until the Press jumped on it... while ignoring the higher rates of abuse on UN missions and in the US public schools. I'm glad they jumped on it... we cleaned house. Now if they would only jump on the others. I won't hold my breath, though.
Where can this data be found?
Beats me. I found some interesting links by Googling "Historical abuse by Catholic Clergy".
Then don't you think that THIS should be retracted?
They are generally lower for the Catholic clergy except for this specific period of time.
