Why did he wait 50 years though? From CNN:
MILWAUKEE, Wisconsin – Terry Kohut has kept a dark secret for nearly 50 years. Now he is breaking his silence, becoming a key figure in the sex-abuse crisis in the Catholic Church and the growing controversy over what Pope Benedict XVI did about it.
When Kohut was barely a teen, and for years afterward, he says, he was sexually molested and assaulted by the headmaster and priest of the school where he lived, St. John’s School for the Deaf, in Milwaukee, Wisconsin. What occurred there is one of the most notorious cases of sex abuse in the Catholic Church.
Kohut was not alone. From 1950 to 1974 the headmaster of St. Johns, Father Lawrence C. Murphy, raped and molested as many as 200 deaf boys, according to court and church documents.
Kohut has now filed the first sex-abuse lawsuit against the Vatican actually naming Pope Benedict, previously known as Cardinal Joseph Ratzinger, as a defendant.
