"Anything that appears in WP should be traceable to multiple reliable printed sources."
However, even "professional" journalists have become so sloppy these days that it's likely that the printed source used Wikipedia as the basis for its information.
I think it's gotten worse with the coming of the web. When newspapers were printed once a day, they had a few hours to check facts and edit before press time. Now that a newspaper is expected to have a story published on the web minutes after it happens, there's much less time to do this. The newspapers have become much more like TV news.
