One crucial point: the entire "repressed memory" syndrome has been widely and consistently declared as being bogus, a horrible and seriously misleading opinion of some very poorly trained (or not trained at all) "therapists" who concocted the notion some 20 years ago.  Extensive research - particularly by various branches of the neurosciences - has dispelled any purported validity to the idea of "repressed memories."  It was a bastardization of the well-known psychological/emotional defenses of the isolation of trauma effects.  This bishop may well have moved abusers around like a chessboard like most every diocese did until recently (and the threat of legal and Vatican charges now hang over their heads) and should be held accountable for those actions if true, but not for "repressed memories" if there is no other credible proof.
