At the very end of an otherwise excellent piece on the Blitz, the insufferably smarmy Brian Williams imparted this nugget of history:

"...just today, just this afternoon, not too far from here, outside one of the new Olympic venues, we happened to look down at the unmistakable sight of pock-marked bullet holes on a stone pillar...a reminder that the war is  not that far off...." (transcript unavailable)

Unmistakable?  Bullet holes?  Who wrote that?  One of the army of fact-checkers at NBC?

Who knew that the Nazis fought house-to-house with the Brits in East London? Tune in tonight, folks -- you may learn about the U-Boats in the Thames.

The author once lived on a bay on a former British island where U-Boats actually did hide.
