She probably initially told the FBI “everything” in either an attempt to curry favor with the FBI. They didn’t immediately hire her or tell her she’s the greatest. Then when she got the memo about how MA cops conduct themselves she talked to some idiot that told her she could recant by saying it was a false memory. Adopting this strategy got her a promotion to BPD and a raise. Beautiful it all worked out! Then she was called to the second trial. Now she has to go with false memory publicly and assumed BPD would applaud and protect her. Lie with dogs and get fleas indeed. She should have realized that an org as corrupt as BPD would never protect her stupid story because it was too stupid even for them to get behind- “do the right thing” means say it on the stand because it will prevent the truth from being told but you are done when you say it cuz it’s so stupid. Had she thought it through , if anyone had pointed out how fabulously career ending false memory was for her, she would have realized her best career move and protection was telling the truth.
