I just looked around a little bit for some kind of indication of how the Patten report relates to the report that has the screenshots you're sending, and I honestly couldn't find anything.
What report are you even linking here, that you're calling the legal investigative UN report? I was able to find a draft version which I linked to down below, but I'm not even sure what you are referencing here, when it was created, or how it relates to the Patten report. It looks from reading the first bit, though, like it was gathered from open sources, remote interviews, and asking Israel's government for information which obviously wasn't very productive. I.e. a lot less thorough than what they did for the Patten report.
Why are you saying the Patten report has been surpassed by the report you're sending screenshots of?
