Coobeastie, you say 'People should teach their children to keep themselves safe', so what would you suggest?,
We have a chap at work, now in prison, a family man, trusted by his neighbours. He invited,his neighbours young girl into his house, to give her, with the girls parents permission, he never physically touched her, but what he was to get his manhood out, and masturbate in front of her..Turned out he had previous of the same, which is why he was sent down.
He was allowed to live where he was, without his past being known, as a result, he re-offended.
If it was up to me, every sex offender, provided the proof is 100%, would be executed.
