"Does this theory also explain the national media's silence?"
I don't know if covering things up at this point is prudent on their part or not. I suppose it might be why they would suppress the story, but on the other hand the more information citizens are armed with the less likely these types of things will succeed. Of course, that's just my opinion - I am by no means an expert on any of this.
From Channel 4 news tonight it looks like the FBI is totally tight lipped about this. I am not sure it is a good idea because any thinking person around here is not buying the spin by the OU Administration.
