Why the hell did this not make any major news outlets?
Why not at least Sports Center?
"Why the hell did this not make any major news outlets?"
The primary theory here seems to be that coverage has been effectively squelched from on high, Homeland Security or above. Why? That's up in the air ... too much information might jeopardize ongoing investigations, it might cause a panic, it might cause economic problems at a somewhat precarious time for the country. It could be a case of denying "glory" and recognition to terrorist organizations, who seek such infamy. Nobody is completely certain.
It's not the first time terrorist activity has been denied for as long as it could plausibly be denied.
