This story will never go anywhere if O'Reilly is smart enough to keep his trap shut. If O'Reilly says nothing, his silence will confirm the truth but he'll never be challenged. If he's stupid enough to open his yap and repeat his lies today, he may actually hang himself.
But he's not stupid.
In the past, O'Reilly lied about his sexual predation, paid millions to silence his victim (and probably paid FOX's legal costs too) and FOX just rode it out.
The predator will keep quiet, and his apologists will too, because they know O'Reilly won't back them up if they vouch for the scumbag. Howard Kurtz likely has already made an orange jumpsuited appearance in the fat man's office, on his knees, promising that he won't say shit.
Pre-Posting Update: I'm completely wrong. O'Reilly really is that stupid.
