If the semantic parity bits add up, then maybe the story does, too. There are plenty of errors in print news publications, too, but there are at least some error-correcting mechanisms in place in print. There really do exist such things as journalistic standards and practices, and it is the job of a publication to report on its own errors. Maybe the errors get printed in inch-high letters on the front page of a newspaper and the correction appears in small type on page 23, but that's just because journalists are as modest as the next person when it comes to admitting error. Still, when the publication is reputable and the error is noticed, corrections do get published.
Online journalism is another matter.
Online journalism, even when practiced by print media operations, often falls below the standards of print journalism. One temptation that online news sources seem to be falling into is a tendency to correct or remove the story rather than publish a correction. On the face of it, this seems like a good idea. In print, all you can do is publish a correction, but in electronic publishing you can go out there and change the story. The problem with this is that some people will already have read the erroneous story.
