Ariel Sharon provokes a stern warning from his own Attorney General: "If they are shelling us, we should shell them," he burst out at one point during the discussion yesterday. But Attorney General Menachem Mazuz intervened. "That would be a war crime, on the part of both the state and you personally," he said, to which Sharon shot back: "It's only when Jews are killed that it's not a crime, and the whole world is silent? Killing Jews is permissible?" "I'm not saying we shouldn't respond, but deliberately firing on civilians is a war crime," Mazuz responded.
