Assuming that she returned for a deposition (again, I don't remember Resistance and Rescue well enough, and there's still time between Blackout and Resistance that is unaccounted for, but I believe she just set off on her anti-WY adventures straight away), and that the insane claims of a single random are properly documented and locatable 40 odd years after the fact.
I'm not going to argue it doesn't sound like a stretch. But just because it sounds it, doesn't mean it's unrealistic either. Plenty of ways around either way. Stranger and stupider things happen in real life.
