OK, OK, I will give you a clue,
Things got serious around 1985:
"There have been an estimated 1,400 sexual abuse lawsuits launched against priests in the United States since 1985."

It is a fact that reported sexual abuse instances have been much less in the 1990s than in the 1970s and 1980s (see Michael Rose's "Goodbye, Good Men."). The average age of ordinands in the 1990s was 32 (same source).
Do you think there might be a correlation?
