I will admit I do personally find the "claimed without evidence" line to be somewhat pedantic at times, even though in most instances it's warranted IMO.
But I think the idea of journalism just being a "police blotter"-like RSS feed falls short of what most people expect and demand from their journalistic instiutions, which is to find facts and holds people in power (especially those in government) accountable for claims that are made when those claims contradict known facts of reality.
So let's say "Trump claimed there are Mexican rapists on the moon" is a fact. However NPR knows another fact that there are NOT, indeed, rapists on the moon. Or, if we want to be really unbiased, "there is no evidence for Mexican rapists on the moon."
Which fact(s) should be reported to NPR's audience?
