The charges against Israel have already been investigated, not only by the IDF but by independent groups as well. The charges have been found to be either false or based on hearsay. Meanwhile, the charges against Hamas have been independently verified, even before Goldstone's report. Yet this is the first news article I read, since the initial news reports, that mentions charges against Hamas. Other news reports on the UN debate only mention Israel.
