My extended family over there knows perfectly well what happened, they just don’t like to talk about it. And my parents know exactly what happened because they were there, and nobody’s coming after them. So without further evidence it seems to be equivalent to certain very contentious political topics in the US, which people are aware of, but you certainly cannot bring up.

Can your extended family research any of it? (search online, read about it in books, etc) Can they speak about it without being persecuted? Can anyone who isn't your extended family find information about it other than through informal channels?

Like what? Please elaborate specifically?

I'm so confused on what your stance is here. You realize there is a big difference between being persecuted by others for saying something or "knowing something" and being persecuted by the government for saying something or "knowing something"?
