Israel gov./IDF/etc. is known to falsify Hamas documents, force false confessions from UN workers using brutal violence and to regularly lie to justify its actions or shape public opinion. Anything they say about the other side means very little without actual independent investigation/corroboration or direct observable evidence. Independent journalists are allowed to go to Israel, so there's no need to lower the standards.

Not independent probe, but more information.
