Wikipedia traces cleansing of political facts to Capitol Hill computers

Would an unpalatable fact been as damaging as exposing your staff as working against free speech?  There's a clear and simple lesson here for anyone interested in public office.  http://news.bbc.co.uk/1/hi/technology/4695376.stm  And why exactly is this a news story I read from the BBC?  Too insignificant for the US media?   Feeling sorry for the Congress in the lack of oversight over their own employees?
