Although there have always been heinous crimes àgainst children I think present attitudes have been formed against the background of the actions of Hindley and Brady.
Parents became aware of the evil of which the 'ordinary' people next door might be capable ... and the freedoms enjoyed by previous generations of children were curtailed ... the adventures children copied and enjoyed ... Swallows and Amazons and Five go to Kirrin Island became too dangerous for the peace of mind of their parents.
I was out of the Country when Hindley and Brady were caught, so I never got the full force of that.
Mine were off for most of the day catching tadpoles, or whatever else interested them.
I used to collect Jam Jars because you got paid for those.
No way did any of mine let their own children have so much fun. They wouldn't even let me buy my grandchildren Air Rifles, although all three of mine had one of those.
I just made sure that they learned to shoot straight, at a target. Of course. That was one piece of parental supervision that I did enjoy
