Maybe I missed something. I thought Israel didn't really cooperate with an investigation because they felt it had a pre-determined outcome to attack Israel. As we all know information gathered from the Palestinians is always tainted. They have been caught lying, exaggerating, fabricating and staging false stories for so long that new terminology had to be created to describe the constant lies. "Pallywood" was the term, ever hear of it. So what are you talking about?
