Even if this final version of the IDF is correct (which we don't really know, the changing story indicates what is well known: The IDF investigating itself, like every organization investigating itself, is likely to result in a whitewash. From IDF history we know that unless a victim is Israeli or foreigner, there is nothing reliable that comes out a case where somebody was killed by the IDF. It's a whitewash on top of whitewash. A Committee of Investigation, headed by a judge and provided for by Israeli law, is the way to go in order to find out what happened. Netanyahu supports this (because he was not involved in the Gaza war), But the Defense Minister (Barak) and the army chief (Ashkenazi) oppose. (They led the war.) They should consider if it is better to be investigated by an Israeli commission or by the Hague prosecutor.
