That's maybe not how it works. If her Agreement is like mine she is allowed to talk to law enforcement about the crime without being seen to have broken the Agreement, and if the perp is prosecuted then found guilty she's covered. If the perp was found not guilty, then she might be open to being sued of course.
Back to my case (as I'm not intimate with her Agreement, or indeed with her). I was not allowed to go public with the allegations at any time, but I could talk to a lawyer/police. Then if they prosecuted I'd have been allowed to testify. If guilty then I'd be completely clear. If not guilty me ex-employer could have sued me, but of course as the evidence was 100% obvious then they wouldn't have, even if they were found not guilty on a technicality. The burden of proof is less in a civil trial and the fraud they committed was clear and obvious (contract claimed to have been signed on a certain date to meet corporate/personal targets, but it wasn't signed till after that deadline).
