I agree it is speculation that she has turned state's evidence.  The only confirms we are likely to get in the near-term are leaks of imformation that have no other visible or plausible origin.  My guess is that the leaks, if forthcoming,  will be "deniable" in terms of being attributed to RC. For example the webcam pix could be from her carelessness on social media. If she is "in the bag", it is strategically and legally important to conceal it for as long as possible.
