I don't think it's a question of honesty. I don't regard it as dishonest if the writer of an article chooses to emphasize (for whatever reason) one comment more than another, or one aspect of a person more than another. If a material fact is left out which substantially changes the emphasis of the article, then that's different, of course, but emphasizing one point over another and leaving out other things is all part of the writer's choice and the reader's opinion.
Writers/reporters have to make judgment calls as to what gets put in an article, and what gets left out. Writers do this every day on their own and then again with an editor.
As for the press being reliable or truthful, the marketplace itself regulates that. When people begin to consider a publication untrustworthy or too biased, they simply stop reading or purchasing it. (a reason commonly given for the decline in the circulation of the NY Times, which may or may not be true or partially true.)
So within the parameters of printing a hot story or sales-inducing article, editors know that if they have to make too many retractions or are proven to be false, they'll lose readers over the long haul. (and possibly pay legal costs as well, although the courts in the United States at least, are fairly lenient when it comes to allowing stories about public persona. The laws for libel are different for perceived "public" people as opposed to private citizens.)
In a free market, the consumer, as they choose to wield it, holds the power of exacting truth from the media.
I notice
you didn't say anything about Clarence Mitchell.
