This high-energy exchange sometimes has everyone talking, or shouting, at once-and the guests in "War Crimes, Part II" (#S9) take serious issue with some of what Mr. Hersh says-but this show does give us a window on the opposing positions on war in general and Vietnam in particular. SH: "The fact is, they're dying. And I can't make up my mind. You know, the more you know about some of these officers and some of the, certainly about the enlisted men, it's really hard to say whether something- You know, Calley was guilty of murder, certainly. But I think the premeditation, perhaps, was in the White House or in the Pentagon. And, you know, I'll leave it there...." EvdH: "You said before that it doesn't make much difference to a man who is killed whether he is killed by accident or by design. You're perfectly right: he's dead in both cases. But the law for the last five thousand years has made a difference whether you kill a man by some accident that you couldn't avoid, whether you kill him by negligence, or whether you kill him by intent."
