I sat through four years of journalism classes and can't seem to remember my professor (who was a liberal) telling me that my job was to "make a difference."
Another interesting point: I was taught that, when a criminal was at large, it's a newspaper's obligation to the public to include a detailed description of him or her. The liberal rag in New Orleans, the Times-Picayune, won't print the race of any wanted offender. You can guess why.
That was then, this is now.
Of course, I may be wrongly accusing you of being old!
