// So no newspaper story is believable then? //
That's not what SP said. Newspaper stories based on what a few random people have said in tweets, however... that's another matter.
Every such story should be taken with a pound of salt. It's not that they *didn't* say it, but usually the tweets are either (a) representative of only a tiny minority, picked up on to look sensational, or (b) ill-informed, people reacting to a TV show without properly understanding what they saw, or (c) both.
To branch that out to all stories newspapers is a textbook example of the "so" rule...
