I will gladly admit that this sort of topic isn't my cup of tea. I'm going by what the article is saying and using terminology that the article uses. I'm concerned that if we start changing the terms, that we might wind up with original research. I think clearly identifying what the core human rights concern is, is important. From the little I've read, it seems that there are mass "disappearances", body parts being found, the mass grave, and such. I've asked WikiProject Human Rights to take a look at the content here since the debate is a little beyond my pay grade as they say.  I still don't quite see the problem with adding a sentence to the lead (once we figure out what prose is suitable for the body), since the purpose of the lead is to summarize content found elsewhere in the article. I'd like to wait for more input, though.
