For all we know, she may have. If she told Liefong she was bailing on him, do you think he would act on that now, before the election? I don't. I think he would keep it to himself. She isn't going to go public. Maybe he's the one she's hiding out from?
You're right - Liefong didn't force her to make the accusation, but he is responsible for where it went from the accusation stage. He has had full control of this from the time she signed on the dotted line. If she really wanted to go forward with this case from the start, the photo line-ups would not have been done the way they were. There are other indicators that Nifong led her by the nose rather than letting her back out through what had been her established M.O. in the past when she pulled a false accusation to save her own butt.
How would the photo line ups be done? She kept picking people.
If she didn't want to go forward, what exactly kept her from saying she couldn't recognize anyone?
