This was a long read, although easy.
A formidable tome of contemporary Urban Legends, thorough, told very much in the breathless style of the invariable narrator of such bollocks.
While very definitely not a fan of the style, a few things I did note:
That the legend often preceded the atrocity, not as a result; incidents for example of Wartime Atrocities in WWI often ascribed to the enemy (but didn't take place) were later enacted in the second War, and did in fact happen.
That reality invariably trumps fiction, overreaches it even, and I recognize many of the legends from headlines, (the reality of the incident is not the point, the point being that they are over-repeated, an attempt to personalize extraordinary events, and whereas an odd thing might happen once there's no way it's happened as often as it's been told).
And that the news - specifically Fox and Reuters, and Paul Harvey ("The Rest of the Story) - have frequently fallen for them, a good headline beating the most remedial of fact checking. Although to be fair most news agencies and media outlets have fallen into the "no fact checking" bracket at some time or another.
Anyways, I didn't enjoy this nearly as much as I thought, and time would have been better spent on Snopes.
