Of course they did, and the record of the past 10 years isn't too bad.
I had a friend who went to a seminary 6 years ago. Before having been admitted he went for a 2-day(!) psychological examination. In his own account, the insults and the questions he was asked were suitable for a sexual criminal rather than for a candidate for the priesthood.
When it was over he was furious at those who screwed up in the past and trashed the dignity of God's call to the priesthood.
I totally disagree with you on this. The RCC has never recognized that any experts had any knowledge she didn't.
Also, the seventies was not a time of recognizing authority.
The problem with this is not pedophilia. It is the men in the church being active in sodomy, condoning it, and the felony cover up of their crimes.
