When I was 16, my parents allowed me into Manchester, to a club where JS was the DJ/Manager. I was allowed, because our neighbour,aged 19 and a responsible, and lovely young woman, was escorting me. On the bus, she told me to avoid JS as he liked young girls. She went on, that I'd probably be ok, because although 16, I was tall and could pass for older. She said anyone of 17 was too old for him.
Police and social work organisations tend to reflect the society they serve. Awareness of the damage of domestic abuse, but particularly, of the sexual abuse of children and adolescents is much greater now, than it was some generations ago. I agree with others, who have said that during the 60' and 70's, women making complaints of rape, or indecent assault were usually treated as 'the problem'. Making false allegations does happen, but its so rare, in comparison with the actual numbers of sexual assault. Guilty findings in rape trials are disappointingly low. No wonder women, or men, who have been sexually assaulted find it so hard to tell.
My experience of working with sex offenders, is they rarely admit their crimes, and if they do, they minimise, rationalise and blame everyone but themselves. I have never met a prolific sex offender who did not have friendships with others who shared his (or more rarely, her) tastes. By our friends shall we (often) be known. From what I read, Bill Roache has been a friend and business partner of Owen Oyston (convicted of rape) and Stuart Hall (convicted of multiple sex offences) for getting on for 30 years.
