"My sense of things is that CGM is in grave danger and that sooner or later they're going to find her dead from an apparent suicide."
This concerns me, too.
However, all she has to do is refuse to press charges or testify, claiming she doesn't want to relive all that.
She's done this before, and nothing happened, so why not just do it again?
Nifong will be off the hook and there's nothing anybody can do to Crystal (she's lawsuit-proof).
How so? Filing a false police report can be a serious offense and those adversely affected can certainly seek redress.
Yes she has backed out of pressing charges before, but she's got different stakes at work in this instance that she probably never anticipated, and a different set of people leaning on her than she's ever had.
CGM is a two-bit ho who probably always does the first thing she can think of to game the system and get things going her way. She probably doesn't think more than one step beyond the next move, which is what has gotten her in the hot water she's in right now.
