The Tucson archdiocese of the Roman Catholic Church has filed for bankruptcy protection, joining the Portland archdiocese in an effort to have claims related to priestly sex abuse of children dismissed or paid cents-on-the-dollar. In the Tucson case, plaintiffs are complaining that the archdiocese has been transferring assets to related entities on the eve of trial -- in their minds improperly attempting to avoid liability. In all the wrangling about the Portland archbishop's institutional wealth, I haven't heard that kind of charge, at least not yet.
