Please do not be naive. This was not a stray accusation from an opportunistic adult, This was multiple accusations to the same people from children.
I would think the bare minimum is when multiple children tell you they are being molested by the same person, you tell that person they are fired if they are seen near a school, and you interview other children at the school. Or you go to the police yourself and ask them to investigate. You know, common sense things. You don't, for instance, do this.
> "As the Archdiocese of Chicago had already placed restrictions on Ray being in the company of minors for nine years prior to his residence at St. John Stone Priory and communicated these when seeking approval from the Provincial, Robert Prevost, Cardinal Prevost was aware of the danger that Ray posed to minors when he gave approval," the letter says. "Nonetheless, Ray was permitted to live at the Priory in the vicinity of an elementary school without informing the administration of the school. By doing so, Cardinal Prevost endangered the safety of the children attending St. Thomas the Apostle."
I would invite you to apply skepticism to the adults who famously covered all of this up, and not to catholic children.
