jno - "What struck me about him was how many people said - after the event, mind - that they always thought there was something fishy about him."
I think anyone with even a passing personal aquaitance of Jimmy Saville would conclude that he was a seriously odd person - but that in itself is not a crime, nor is it an indication of criminal behaviour.
So it seems perfectly reasonable for people to be wise after the event - which is common in almost any circumstance.
I remember as a twelve-year-old visiting the station master at a local village station where by grandmother lived - he was a friend of hers. One time i called and he was on holiday, and I asked for a glass of water from the guy filling in - I had cycled eight miles and it was a hot day. I remember thinking he had strange eyes, a rather intense stare.
A year later, he got life for shooting four French campers as they slept in their tent, it seems they had 'looked at him in a funny way' in the pub earlier in the evening.
I remember thinking about his odd eyes - but that was in no way an indicator that he was a sociopath - but as i said, it's easy to see these things with hindsight.
