Let's look at the quote right after Michaelr's, despite his suggestion that his quote is the only significant sentence in the article:

"The exculpatory evidence comes not from government or military officials in Israel, who have an obvious interest in claiming that their soldiers weren't responsible, but from other sources. In fact, the Israel Defense Forces, or IDF, seem to prefer to soft-pedal the findings rather than bring any more attention to this gruesome episode. The research has been done by a variety of academics, ex-soldiers, and Web-loggers who have become obsessed with the case, and the evidence can be cross-checked."

Now if you wish to suggest that Israeli academics are always bound to find the government innocent, you don't know a lot about Israel or about academics...and a lot of Israeli soldiers and ex-soldiers are sympathetic to the plight of Palestinian Arabs, even to the point of refusal to serve in occupied territories. So I think this is as close to an objective set of findings as there will ever be on the issue.
