Very sorry to hear that Ray, I hope you made a full recovery.
From what little I know about these matters, I would assume this was his first offence for the crime off assault. Our system allows you to commit your first offence, and get let of with a caution, as long as you acknowledge what you did was wrong, and you show regret. The crime is recorded, and if you commit a similar offence again, the second time you are charged. His caution will be on his record. That is certainly the way it works with shop lifting, and I am sure I heard you also now only get a caution for your first burglary.
From what happened to you, your cynicism is understandable. I was one of those who posted a welcome to the new legislation, as it just feels like a step in the right direction.
You do raise a very valid point about how do you define what a sub culture is. I used to dress full on punk 20 years ago, ripped cloths, the jacket, the hair, the lot. That then was more black and white. But, are you sub culture if you where an Iron Maiden T shirt, or just like having your hair long if your a bloke. Will your taste in music be a ruling factor. Will you have to be punk, goth, emo, or any other alternative follower, or will it just be the way you are dressed or look. The barmaid at a local pub to me has terrible taste in music, liking any old fodder that shows up in the charts. She dresses quite normally, but she is covered in tattoos. Will that also rate as being sub culture ?
Could prove to be interesting when it is first used in Court.
Again, sorry to hear what happened to you Ray, don"t let it change who you are, and give the bastard a victory, he doesn"t deserve it.
