TS, around 95 I had to try a charge against one of my airwomen for having a man in her room. She committed no greater sin than giving him a coffee to help sober up before he went home. The RAF Police didn't hesitate to charge them.
In this case, she appears fully dressed which overall appears odd. Maybe she only felt assaulted in retrospect. Nothing against that of course but it could explain why there was no complaint at the time.
In retrospect many of us will believed we were wronged in the past or hadn't complained as it was not the done thing. When I did completely as a civil servant I was assured that my complaint was groundless . I am pleased to say the individual I complained of moderated his behaviour.
