The articles, produced TV pieces, etc and produced and stockpiled well in advance. There are obit files on everyone who is anyone. All that needs to be filled in is the date and cause. Case in point: I was listening to WTVN, Columbus when an erronious report that Bob Hope had died surfaced (he was not dead at that point). They go to an ABC report "This is an ABC News Special Report. Bon Hope has died. (Cue the pre-produced bio "Bob Hope got his start in the 1920s, etc, etc."). Report ends, ABC News guy says "this just in, Bob Hope's publicist indicated he has not died".
Perhaps "omitted" was the wrong word. What I was eluding to was that in cases of a public figure reaching the end of life it seems a few days before their death a story appears that the individual has some hint they are not doing well. I believe in Aretha's case I saw an article that said she had been admitted to hospice care then two days later she was gone. In McCain's case it was the next day after the announcement he was stopping treatment. In both cases there was no clue that death was eminent. In my mind these hints seem to be orchestrated to give the go-ahead to the nation's media to prepare the articles which will be published when word of the person's demise are announced. There have been many other examples of this same treatment over the past few decades.
I am not criticizing either person's family or representatives but it seems to me our national media has established a protocol that was never warranted.
