There is NO SANE PERSON ON THE PLANET who would watch that documentary and when it was over express indignation at the language used by the people who were there watching those events unfold in front of their very eyes.
Bingo. I think we have a diagnosis. :)
All things considered, I am surprised there was so little profanity.
It was very natural in that context, and (unlike Janet Jackson's breast) not the least gratuitous.
Most important of all, it is a record of actual events, not somebody's slant on those events.
