Ratzinger Knew

Not that this can be in any way a surprise:

An initial statement on the matter issued earlier this month by the Archdiocese of Munich and Freising placed full responsibility for the decision to allow the priest to resume his duties on Cardinal Ratzinger’s deputy, the Rev. Gerhard Gruber. But the memo, whose existence was confirmed by two church officials, shows that the future pope not only led a meeting on Jan. 15, 1980, approving the transfer of the priest, but was also kept informed about the priest’s reassignment.

How can someone who is the problem also be the solution to it?
