Premise: Oliver Francis O'Grady (born June 5, 1945) is an Irish laicized Catholic priest who raped, molested and abused at least 25 children in California from 1973 onwards. His abuse and Cardinal Roger Mahony's attempts to hide the crimes are the subject of Amy J. Berg's documentary film "Deliver Us from Evil" in 2006.
Hypothesis: Cardinal Roger Mahony was eventually unsuccessful in hiding the crimes.
