I think it was KFOR that did a lot of serious investigative reporting into the Oklahoma City bombing, and was ignored by the rest of the media. They are an NBC affiliate, too.
Just a note on that... Journalists are regularly recruited straight from Chicago to NY. The “local” Chicago affiliate is no small potatoes station in comparison to OKC (sorry, no offense meant). Also, the journalist at KFOR who was investigating the story was canned there — she later wrote the book “The Third Terrorist”. That AWESOME reporter’s name? Jayna Davis.
