You may be right -- there is, of course, the apparent "attempted blackmail" of Cardinal Medeiros (which Medeiros did not seem to take seriously, at least judging from the copy of an "unsent" letter I recall) and Shanley refers somewhere to his own molestation at the hands of an unnamed "predecessor" Cardinal.
The Boston Globe seems to have removed the documents it got under FOIA from its website; it would have been handy to be able to refer to them.
I wonder if the press has access to Shanley in prison. I can't imagine they wouldn't want it and try for it. I don't know the laws -- maybe the press can't have access to prisoners until after conviction.
