trisher, not all girls of 16-18 who have relationships with powerful men (not entirely sure what you would define as ‘powerful’) are acting under undue influence. They might feel flattered and make unwise choices (wasn’t it ever thus?) but unless violence is involved or they have been drugged it’s not illegal unless it’s a teacher-pupil or healthcare professional-patient relationship.
You referred in an earlier post to ‘rich, powerful white men’. I believe far more harm has been done, and probably still is being done, to very young girls in care by predominantly Asian gangs who have groomed and abused them. These are very young and vulnerable girls with broken lives who think they are being shown love when they are bought gifts. I don’t think what Epstein, and certainly Ward, did compares.
I agree that the missing police documents in Ward’s case is suspicious and I believe he committed suicide just before he was due to be arrested, perhaps tipped off. It does smack of corruption but of course at least one top politician was amongst those involved in the parties and doubtless many other powerful men, also there was far more police corruption in those days.
