Media MYSTIFIED after Dem. donor threatens 6 "unknown" SCOTUS justices

An Alaskan man who is a registered Democrat and has donated to ActBlue was just charged after allegedly harassing and threatening SIX Supreme Court Justices. However, the media is mystified and making sure to disclose that it is UNCLEAR which Justices were facing the harassment. With the current ideological makeup of the Court being 6-3, is it really a difficult puzzle to figure out which Justices may have been targeted?
