This PhD is chiming in to agree that @cobrat’s assumption is bogus.
“Only” having an MA is a red flag (or, at least, an insufficient credential) for someone who followed a normal academic path. If you’ve spent your life in the academy, then you’d better have gotten the highest credential possible. There are, however, countless examples of non-PhDs with substantial, relevant professional experience in other walks of life assuming various kinds of faculty positions at top universities.This is occasionally true even in my field, English literature, where there wouldn’t be that many obvious routes to obtaining equivalent experience. It is much more common in a field like poli-sci, where actual, lived experience in the government or military might well be (gasp!) more useful than theoretical knowlege in certain situations.
On topic: I don’t think this prof has a leg to stand on, if the allegations against her are true.
