When I was a kid back in the 70's, we as kids knew who and where the pedo's were. They were in all walks of life, vicars who held discos and kids clubs at there churches, teachers male and female doing after school clubs, we learnt to avoid the risk of being abused through others mistakes, so we just gave them a wide berth. They lived in the community with everyone else. It was all common knowledge. And you knew if a kid had been abused, because the whole family would just up sticks and move.
