Sorry, I misunderstood your post. To explain: I think that early on, Nifong DID believe a rape occurred. By the time he learned there would be no DNA evidence, he knew of the pregnancy, and hung his hat on the paternity. Of course, that does not explain the, "they used condoms" comment. Like I said, Nifong is not playing with a full deck.
Yet, according to his bio, Nifong is Phi Beta Kappa. I think his actions speak more to his having excessive hubris.
He got the first report back from the state within weeks.
He got the one from DNA Security on April 28th.
