That's just not true as a matter of what reporting is. Sometimes even good reporters dig, and get evidence that they know is less than metaphysical proof but is enough to convince them it probably is true and the story is worth reporting, and then they turn out to be wrong. Stuff happens. If you only want reporters to report what is metaphysically true, all they will do is report what public actors tell them happened in press releases and is o.k. to report. We wouldn't have ever gotten to the bottom of Watergate, as just one example.
