That strikes me as some sort of backwards reasoning, people had to literally break into FBI offices and steal documents so that those things would come to be known. You can't really fault the news for not reporting on something they had, unless I'm mistaken, absolutely no way of knowing unless they were to, y'know, infiltrate the FBI.

The burglary was in 1971, and the MLK letter didn't get published until much later. These days the documents would get uploaded to Mega or sent to Wikileaks, and dozens of people would pore over them.
