Do we really want the mainstream media determining what’s “false” what a track record they have so far. We should trust people to judge for themselves.
Responsible journalism is not about determining the truthiness of the material. It is more about ensuring the credibility of the information, by getting multiple sources and not reporting hearsay or tweets with no sources. Responsible journalism should include important context and not make or report hyperbolic statements by people with an agenda
Sure, but each newsroom, and maybe even journalist, has their own interpretation of what is "responsible".
