No society has become obsessed with padeophiles and people like you would have us all living in fear. Most of the cases of paedophilia come from the good ole days. On Thomson he was very young when he committed the crime hasn't since. Should he have eyes on him forever, probably yes he should. But what do you do with these people if you did what you'd say. If you didn't give them second chances they would more likely reoffend and you would have more sexual predators. Get on with life and stop living your life in fear.
Yes I have sympathy for his victims, no I have no support for him. I fully don't expect someone like you to understand my point of view
