If this story keeps showing up in the news, but without any real information, I’d suspect that this constant simmering vagueness belies undisclosed information locked behind operational secrecy that prevents the public from understanding the media pressure and the suspicion.
This is to say, fingers are being pointed, but we only receive incomplete information. It’s sort of like seeing two neighbors bicker about trash collection and garbage cans, but they leave out glaring details about known trash can abductions by space aliens, that they’ve been summoning with multi-colored LED flash lights.
