Here's the owner:
Local TV LLC is a limited liability corporation owned by Oak Hill Capital. The company was created in 2007, after Oak Hill entered into an agreement to purchase the nine television stations owned by The New York Times Company.
Local TV LLC took ownership of the stations, all located in medium- to small-sized markets, at 12:01 a.m. on Monday, May 7, 2007. Randy Michaels, the former CEO of Clear Channel Communications, was originally CEO. Robert Lawrence is President and COO. On December 20, 2007 Local TV announced that Bobby Lawrence would be CEO.

Local TV has become a somewhat large player in the TV industry as of late. I don't know much about them, but former CEO Randy Michaels, though reported to be a conservative, also is a part-owner of Ed Schultz' radio show. He's not into using media as a bully pulpit, rather he's into putting out what he thinks is compelling product that will be successful.
The fact that they re-ran the piece on their evening newscast does give some credibility to their claims of a technical malfunction. I have little reason not to buy it. What little I know of this company does not make them out to be some sort of propaganda outlet like, say, Sinclair.
I would also think that this story is very big in Alabama, and there's really no way they could get away with blanking it out without a mass newsroom revolt. Unless, of course, the station was owned by Sinclair.
