That'd be the first time that Rather got anything right. Did you watch the first airing?
I did. They went back to the town in Italy where this priest came from and found filed allegations of abuse by the priest with minors along with sharing drugs with them. The L.A. Archdiocese apparently didn't lift a finger to find out who this priest was and basically let him start serving from off the street. The priest spoke two or more languages and that's what was needed so they let him in with practically no questions asked. IIRC, another Archdiocese in CA even tried to warn them of this guy after he tried to get a job with them, but nothing was done.
In any case, if any part of this HDNet report is bogus I would expect to see a response/defense in the media sometime very soon.
