Ideally, it would be done all at once- for each professor in the US who wrote a technical thesis, identify all sections which can reliably be considered plagiarism (direct copying without attribution, for example) and publish a national report.

That would then expose the base rate of plagiarism, which I believe is extremely high (I could not say, for certain, whether I did it in my thesis, although I worked extremely hard to follow every academic rule associated with technical writing, and would be surprised if there was any text, other than from the papers I had already published, that was directly copied).

Once the base rate had been exposed and people kind of see just how much of this occurred, we can start to have the discussion of "what are the consequences"?

The consequences to Neri are just reputational- she already left her professor role and it's unlikely she needs her reputation to continue to be wealthy/successful/attend the hot parties.
