I remember he also pointed out the self-censorship journalists go through as well. They think they are free to report on whatever, but especially earlier in their careers they learn that certain stories will be rejected by their editors or if accepted by editors, anger comes their way from higher ups. And from those experiences they learn to not write about certain things because they know it won't reach print or air on TV.

I also have the book saved on my e-reader and tried finding the part you talk about (I remember reading it) but couldn't find it.
