I've got two new heroes. Their names are Cindy Michaels and Tony Consiglio. Until last Tuesday they were the top journalists and news anchors at a small TV station in Bangor, Maine. Then they quit. On air. So why are a couple of on-air anchor resignations enough for me or anyone else to add their names to the pantheon of journalistic heroes? It's because of the firewall these two respected -- and paid for with their jobs.
