The bottom line is that it does not look good for Israel to be rejecting a U.N team for any reason.
And if you want to argue that theU.N's biased because it has endorsed resolutions condemning Israel, does that mean that all of it's resolutions vis a vis Iraq should also be ignored?
Oh, yes it does. If they are collecting forensic evidence, fine. If they are going to take "eyewitness accounts" without physical coroboration, then this will be an exercise in propaganda, and at least two of the three on the committee have a record of being very quick to believe anti-Israel and anti-Jewish rants.
