Why are you assuming I haven't? Anybody that disagrees with the author automatically hasn't done the necessary research, in your mind?
I appealed to Morley Safer's incredibly long history with the program for a specific reason. The author of this piece charges 60 Minutes with slander, which is a very big word, and journalists don't have multi-decade careers when they're stupid enough to open up their company to claims of slander. Particularly on a (to them) relatively unimportant story.
