Regarding the Dean Scream: doesn't bother me. When you've listened to the hours of audio recordings by Maurice Duplessis (en Francais, bien sur
) and Bobby Kennedy as I have, you become jaded on these questions. 
Oh, they were armed. In French we call their weapons "bons mots."Normally RFK would sneer at someone who pissed him off, along with that rather intense glare of his. You don't see that in the photo, because it's in public.
There are accounts of LBJ putting his arm around RFK during the '64 campaign and saying "this is ma boy, I want ya to elect my boy." Lyndon is 6"4, Bobby is 5"10, and he is young enough to be LBJ's son, so you can just imagine the aesthetics there. As the author so memorably wrote, "you could see the white on Bobby's knuckles."![]()
