So I have received information from someone who attended a talk given by the Priest-in-Charge (what SSPX call "Pastor") at the Chapel/School involved. I'll post the details as I hear them without making any commentary until a subsequent post. So the priest started by instructing people not record the meeting without prior permission.
Reportedly he appealed to moral theology regarding "detraction" to explain why the SSPX did not divulge the information sooner, explaining that they divulged it on a need-to-know basis only, based on a determination of whom they judged migth potentially have been at risk.
Since no one has commented on this, obviously there can be no detraction when 1) a crime is public or notorious or 2) the public welfare requires spreading the information. In the case, BOTH are true.
One might question who they're REALLY worried about "detracting," Father Stafki or themselves and the SSPX?
But one could argue that in the "spirit" of not detracting, unless there's a "need to know," one still SHOULD not spread information even if it's public with someone who hasn't heard about it unless they might be affected, i.e. unless they have a need to know.
So it would appear that THEY would be the ones to determine this "need to know" based on their own "contact tracing" exercise ... as if they knew or could possibly know the whereabouts of this priest at all times. Unless you can establish with complete certain exactly where this priest has been the entire time, the public good required an APB (All Points Bulletin) "Be on the lookout for ..." They have NO IDEA how far back this propensity to sɛҳuąƖly assault children goes. In the 8 years he's been a priest, he could have had contact all over the place with numerous faithful, from his original time in Kenya. And he was allegedly on sabbatical, where they obviously would have had even LESS idea where he was. So there needs to be a widespread public alert. While I think he's safely behind bars (or did he make the $75K bail?) at thsi time, with an APB, if the individuals who know they had contact with Fr. Stafki were alerted, perhaps they could think back about other possibly suspicious behavior along those lines, where perhaps for instance, with the benefit of this new additional hindsight, something that may have at the time been written off as innocuous, might now be recognized for what it could very well have been, say, grooming, or additional abuse. So one parent might say, "Wow, I let my son go hang out with this priest, because the priest told me he might have a vocation and would make a good priest. Thought nothing of it at the time, but now I'm beginning to have questions." It might cause additional victims to be identified either by their parents or inspired them to come forward themselves ... so that they could receive the help they might need to help them recover from the trauma.
Finally, the honor of the SSPX and Traditional Catholicism are at stake. By preserving the "reputation of this priest" (as you allege), you're making not only the SSPX but all of Traditional Catholicism LOOK BAD. This terrible publicity along of giving even the APPEARANCE of covering it up, with some people refusing to become Traditional Catholics after having been subjected to the various CM stories (quite possibly their ultimate goal) ... all those are sufficient interest of the public good that not only permit but even REQUIRE divulging whatever information they have that would that might be of us (no, the pornographic details are absolutely uncalled for except insofar as some of the "tactics" he used to groom teh child could be exposed).
