These historic claims are very difficult to prove, unless there are multiple claims they are unlikely to result in a criminal conviction. A civil claim involving compensation is much easier to determine but then it’s the incentive of a wealthy man who can pay. There will be more cases because any wealthy public figure that had a relationship with a young junior makes himself vulnerable to a claim years later.
Working as a young nurse I was groped by patients many times, a couple of times by other staff, it was a hazard of the job, you brush it off, I’m sure it’s not as bad these days, 40 yrs ago it was bad!.
