The trouble with censorship

This Reuters article is about editors at a newspaper in China who were fired for allowing an advert honoring the mothers of those killed at Tienanmen Square. It's a relatively heavy piece for Oddly Enough, which tends to highlight incompetent criminals, wild animals wandering through cities, and the like. I think this story got filed under "odd" because of how the advert got in the paper. It did not refer to Tienanmen Square by name, mentioning only "June 4". Thanks to the effectiveness of state censorship, the young clerk had no idea what June 4 meant, never mind that it might be something verboten.
