• In his eight years as a professor of theology in Regensburg, in close contact with his brother Georg, the capellmeister of the Regensburger Domspatzen, Ratzinger can hardly have been ignorant about what went on in the choir and its boarding--school. This was much more than an occasional slap in the face, there are charges of serious physical violence and even sexual abuse.
• In his five years as Archbishop of Munich, repeated cases of sexual abuse at least by one priest transferred to his Archdiocese have come to light. His loyal Vicar General, my classmate Gerhard Gruber, has taken full responsibility for the handling of this case, but that is hardly an excuse for the Archbishop, who is ultimately responsible for the administration of his diocese.
• In his 24 years as Prefect of the Congregation for the Doctrine of the Faith, from around the world, all cases of grave sexual offences by clerics had to be reported, under strictest secrecy ("secretum pontificum"), to his curial office, which was exclusively responsible for dealing with them. Ratzinger himself, in a letter on "grave sexual crimes" addressed to all the bishops under the date of 18 May, 2001, warned the bishops, under threat of ecclesiastical punishment, to observe "papal secrecy" in such cases.
• In his five years as Pope, Benedict XVI has done nothing to change this practice with all its fateful consequences.

demands that Joseph Ratzinger himself, the man who for decades has been principally responsible for the worldwide cover-up, at last pronounce his own "mea culpa".
