The headline of the article you linked indicates that NYT was presented evidence from their headline.
Israeli officials have presented evidence they say ties workers at a Palestinian aid agency in Gaza to violence during the Hamas-led attack on Israel.
You are correct it’s mentioned further down in the paywalled article in a part that is not readable without subscription. So NYT is writing spectacular headlines about presented “evidence” which has not been presented. I thought that the leaked dossier was about the evidence? Maybe I’m not reading that correctly then
What NYT did is bad framing of a narrative with plausible deniability. You can score brownie points there if you want so you get 1/3.
