The IDF has a very poor record of prosecuting its own soldiers for crimes against Arabs. It hardly ever does it. By the law of averages, the IDF must have committed a fair number of crimes over the decades of fighting, and certainly there are loads and loads of accusations, but somehow the IDF always seems to manage to whitewash itself. In this instance, the Goldstone report means that a total whitewash isn't feasible, so one minor pawn is sacrificed to try to convince the world to drop the Goldstone report.
