Sorry, but the killing of unarmed civilians seeking aid has been reported half a dozen times by many different outlets. The IDF denials are getting quite absurd. The only one suffering from disinformation is you.
There is a point at which pleas to wait for "better" evidence can be construed as denials.
"There is ample evidence and this is not a new accusation, so your request to wait and see rings hollow and appears to be a de facto request to not pass judgement on Israeli crimes" is neither morally nor intellectually dishonest.
