Whoa, this is a pretty damning indictment of a sitting pope:
In 1980, the future pope reviewed the case of Father Hullermann, who was accused of sexually abusing boys in the Diocese of Essen, including forcing an 11-year-old boy to perform oral sex. The future pope approved his transfer to Munich.
It would be one thing if the then Archbishop Ratzinger had totally ignored the allegations – at least then he could say that he didn't believe them. But the fact that he moved to Munich "for therapy" indicates that Ratzinger had at least some inclination that something was amiss.
