THIS ISN'T A SOLUTION TO THE "FAUX NEWS" PROBLEM

But it is interesting that back in 1922, Walter Lippmann, in Public Opinion, recognized that there was no formal recourse for a reader who felt he was mislead by a newspaper:

Now it is interesting to note that the general reader of a newspaper has no standing in law if he thinks he is being misled by the news. (p.329)

Lippmann suggested that we have an outside panel judge the accuracy of newspaper reports:

The reader will not mistake this as a plea for censorship. It might however be a good thing if there were competent tribunals preferably not official ones where charges of untruthfulness and unfairness in the general news could be sifted Cf Liberty and the News pp 73 76 (p. 330)

However, even with FactCheck, Politifact, FAIR and Media Matters, wingnut propaganda is still often very effective.
