As to an international investigation, every single one of those involving Israel has had zero credibility amongst serious jurists. The Goldstone Report was commissioned by an anti-Israeli organization and 4 of the 5 members of the Panel had in the past taken viscious and imbalanced anti-Israeli positions. Israel, rightfully, doesn't want to hold commissions every time it exercises the right of self defence. Israel's judicial system has tremendous integrity and widely respected. Leave it to them, especially given that there will be international observers. As to your math, 51% thinking that Israel was at fault for the killing of the "peace activists", your a complete transparent idiot about that, either that or you can't or simply didn't read. None of the possibilities surprise me because that is the way of the world with the sympathizers, aiders and abettors of Islamic terrorism and imperialism. The story says explicity that 49% think that the violence was the fault of the activists, 32% said they were unsure and 19% pointed the finger at Israel. Of course, we all know that the 19% are wrong headed and wrong hearted and couldn't care less about the facts.
