Not a very big story IMO. The word should've been edited out, but it is no big deal. The word is at most a vulgarism, nothing more. I wouldn't use the word in making a closing argument to a jury, and I wouldn't want my kids using the word (at least in my presence ), but it appears to be an editing mistake, nothing more.
Words such as the one in question only become a big deal because people make them such. Moviegoers wouldn't have laughed when Butch and Sundance yelled the word when they jumped off the cliff had the word not been "forbidden."
