The camera at war

I think the picture you are looking for is in the documentary
 The camera at war. It also has film footage of the same thing.
It is the easter holidays here in England
 but i will get the film from the college libuary when it
 re-opens. I am trying to put together a seminar on the Vietnam war and the US governments attit6ude towards documentary film.
if you have or know the whereabouts of a copy of "why Vietnam" could you please let me know.
