People she doesn't know

Yoram Meroz described this to me as a "lovely ambiguous headline": "Clinton aide Huma Abedin has told people she doesn’t know how her emails wound up on her husband’s computer", Washington Post 10/29/2016.

Yoram didn't specify the ambiguity, but I presume that the issue is whether Ms. Abedin [told people [she doesn't know how it happened]], or rather [told [people she doesn't know] [how it happened]].

Bizarrely, the Berkeley parser finds a different structure, where the apostrophe-s is a reduced form of "is" rather than a possessive, and some weird stuff is going on as well with "doesn't":
