I remember when I was nine, Sargeant Adie, who lived in the police houses along the road from my parents' shop, caught me go-karting on our local 'cut-through' paths, and advised me about the dangers of knocking over someone when i came round the blind corner at speed.
When he caught me again a week later, he told me he would take my go-kart down to his police station and chop it up, and I could stand and watch.
The fear of that threat - plus the fact that he knew my parents - made sure I never karted there again!
Looking back, I know that his somewhat unorthadox approach (!) would not be allowed today, and I also know that his physical size would mean passing a medical would be highly unlikely!
It is a reminder of the times when children did as policemen told them, and a stern warning would stay in your mind for fifty-one years!!!
