Okay, I'll bite. You said:
today on NPR the head of that UN agency which produced that conclusion of genocide in Gaza failed to give proper definition of genocide which was the very first question by the interviewer. The part she omitted? She omited "committed with intent to destroy, in whole or in part, a national, ethnical, racial or religious group,"
From your link to NPR's transcript of the interview:
CHANG: So first, can you just define for us what is genocide, according to the U.N. Genocide Convention?
PILLAY: Firstly, it's accepted by all that genocide is a monstrous crime, an extremely serious crime, which is the killing and destruction of a people in whole or in part. That's why we say it has a specific overarching intent.
The phrasing is a bit clumsy (e.g. "that's why we say") but the idea that Pillay is trying to sneakily hide something here is rather bizarre. It seems very likely that "specific overarching intent" is meant to refer to the specific clause you highlighted. Obviously a live radio interview is going to be a bit less polished than the final written conclusions of a two-year study; that hardly implies malice.
