I mean she isn't claiming she was assaulted. I get that she could be doing it for attention but beyond that what's the motivation? The guy died, so the NDA died with him.
Could be true, could be not true. Don't dismiss attention as a big motivator though, especially with virtue signalling attached.
The story definitely smells like bullshit to me though.
1. I have no idea of the level of Fame at that time in southern California for Kardashian and Shapiro (assuming this is before the trial), but it's not necessarily common that a law student would instantly recognize a big local lawyer. Especially a law student whose grasp of the law is so tenuous that she would immediately switch majors upon learning that (gasp) there's unscrupulousness among lawyers.
2. There's no indication that the meeting had anything to do with OJ until the boss told this person. If it was such a big secret and the boss made her sign an NDA for knowing it, why would he tell her at all given that she didn't need to know?
3. The NDA would also protect not just OJ's reputation but also her boss and USC. Why would the consequences of the agreement end just because OJ died?
