This is bringing about such interesting discussions. Many sex offenders are 'nice' blokes who know how to get on a level with people, are 'emotionally congruent' with children, and manage to invoke such utter disbelief that they would ever do anything untoward, which is why they get away with it for so long.
Men who have 'date raped' when they were in their teens and twenties are facing allegations now they are elderly, when women who have lived with the memory of those attacks see in the media that the likes of Savile have died and escaped prosecution. I have heard from ex-colleagues that the numbers of complaints are steadily rising, motivated by some confidence that victims can at last get justice or some degree of 'closure' (their words) for what happened to them so long ago.
I have liked Rolf Harris ever since I saw him in Animal Clinic. Always thought he was a talented artist, but gauche and a bit naff before that. If he has done anything wrong historically, perhaps he has since set out to try to be a better person. If he has harmed someone, he should face the consequences now, no matter how old he is.
