"However, the Harvard Kennedy School cannot ethically stand behind academic work advocating a national policy of exclusion and advancing an agenda of discrimination."
A petition with 1,200 signatures collected by Harvard students, who seem to want an investigation targeting this one case, because the conclusion offends them. It seems to me the investigation ought to be much broader, into what the general standards are at the school. The students have a big interest in whether the degree means what it's supposed to mean, but the one dissertation they loathe ought to be presented as evidence that the school has low standards, and the investigation ought to range across the political spectrum. But the students are speaking in terms of which policies are ethical, and that sounds like they want a political standard to restrict research, which, ironically, would not be an ethical policy.
