I had a Police caution when a kid, from riding on the pavement, I'd have probably got off with a telling off if I'd not been cocky:
PC – Son, here
Me – What?
PC – You are riding on the pavement
Me – Not really (technically yes, but I was 'trackstanding' with a friend as he walked on an empty pavement home from school)
PC – Whats' your name?
Me – John Smith (name changed)
PC – And whats' your dads' name (small town)
Me – MR SMITH
So he took my details, and a few weeks later my folks received a letter that I had to meet with the Chief Constable for a Police caution.
My mum (no nonesense Yorkshire lady) took me, and let the copper read what he had to do, and then berrated him for a good 5 minutes on how he ought have his guys out dealing with real-crime. He couldn't get a word in edgeways, and at the end apologised for all the inconveniance.
As we left, I said sorry to her – and she said don't be daft, and don't worry about riding on pavements – he won't have us in there again.
