This is a book by Deborah Lipstadt.
I haven't read it yet but my daughter is reading it. The subtitle is the American press and the coming of the Holocaust 1933-1945.
I bring it up because she keeps telling me that what this writer uncovered is happening today. Basically, the press knew what was happening in Germany and didn't report it or they downplayed it--their actions and where and when and how they printed stories shaped the news. For example,the "Stop Hitler" rallies in the US which were to publicize what Hitler was doing to the Jews was ignored by NBC, CBS, etc. Other times they buried the story in a small paragraph somewhere inside the paper. Because of the press' action many people had a hard time actually believing what went on in Europe at the time when they did get some information.
There's a section about how certain acts of violence were characterized as youthful acts of misbehavior. Reminded us of the characterization of young thugs overrunning retail establishments etc today in places like Chicago. The press is using the same tactics described in the book. People think they're so smart and they don't realize how they're manipulated.
Anyway, I plan on reading it. Thought someone else might be interested.
