This is no excuse at all but it was all so different then. I remember the term 'kiddie fiddler' being bandied about when I was growing up and people just seemed to accept that some men were creepy and kept away from them but not enough to warrant any police involvement. It's awful.
Thinking about it, I thought most of those TV presenters were weird old men in some, way, shape or form - Forsyth, Savile, that guy from 'It's a knock out'.....
The whole concept of consent was very blurred too. I've said this before but I remember watching an old Carry on film where part of the 'plot' featured a young, posh woman deciding to travel on her own by train (think it was 'up the khybe'r). She was warned it wasn't safe as men would 'have their way with her' but she went anyway. There followed a scene where a succession of men went into the train carriage and pulled the blinds down. So we were supposed to think she was either just accepting of it all or was being raped and it was all a 'laugh'. Times have changed a great deal and all the better for it. I still can't see how he could get away with it all though. The sheer scale was horrific.
