One of the worst things that has happened to journalism is the emergence of these dopey "fact checker" features - and in some cases, entire web sites - purportedly written by people who authoritatively cut through the B.S. you hear in the coverage of politics and government and give you the straight scoop about what the truth really is. In fact, they are little more than opinion writers who have assigned themselves official-sounding titles that they hide behind to disguise their bias.
