I don't think the police or the KBI are in the habit of conducting investigations "for the sake of pot-stirring."
You can read the emails from the SSPX that show incontrovertible proof that SSPX leadership knew of priests committing crimes. The dates on the emails are 2019-2020.
Neither CM not the SSPX have released the full text of those emails. Nor do I expect them to. Until they’re available in their entirety we really can’t say what the SSPX knows or doesn’t know. You can selectively quote a docuмent (as Voris & Co. clearly did) to make it seem to say whatever you want. Anyone who has graduated from high school probably has enough life experience to realize this, but it is nevertheless an effective tactic for making someone look bad, to the casual observer.
If they quoted the most incriminating portions, as they surely did to prove their point, it tends to largely exonerate the SSPX, because frankly there’s not much there. The SSPX leaders are, of course, strategizing how to respond to Jassy’s media disclosure and the loaded questions from CM, whose reputation is well-known. When you know somebody’s about to throw rotten eggs at you, whether deserved or undeserved, you start examining your poncho collection.
