Linda Greenhouse, winner of a Pulitzer said that journalists have to do their best to provide not just the facts, but also — always — the truth.
Journalists should be as transparent as possible about sources and methods so audiences can make their own assessment of the information.
We are in a world of "expanding truth", where everyone who is knowledable about something, and has a bit of exposure, talks in the news about a trending topic. Facts should be checked. ALWAYS. That's what distingues knowledge-based from fact-checking. In one, the person speaks just because he/she has a knowledge about something, but most of the times, facts are not really checked.
