Father Thomas Doyle has testified Archdiocesan officials had a duty to fully investigate allegations of child abuse by priests and to take appropriate action, including removing dangerous priests from ministry, which authorities allege the Archdiocese — and specifically, defendant Monsignor William Lynn — did not do.

But, the defense highlighted that it was Monsignor Lynn who compiled that list. The defense says he did the right thing in trying to identify predator priests and the Monsignor had nothing to do with the shredding.

The defense also emphasized it was the Cardinal, not Monsignor Lynn, who had final authority on priest placements.
