I sat in meetings with my father, who not only wrote his own news but was a news director as well, when he would go around with each reporter and say, Go back and make sure that these sources are good sources, and if you dont have two then we cant use it. I also witnessed what many broadcasters feel was the downfall of broadcast journalism, when they sent my father to these consultants who would say stuff like, Part your hair on the left and not the right, and wear a cool blue suit because that means confidence
