Okay, let me put this in a more simplistic way
1stly to Deborah, the answer is pretty much no, you can't defend yourself, if a 10 yr old comes at you & punches you, it is going to hurt, just cos they're 10 doesn't mean they can't hurt you, if you lash out at them, or restrain them, you as the adult will be arrested for assaulting a minor, i'd still do it anyway but that's beside the point, the same goes for smacking your own child, you are not allowed to....again if I think my kid needs a smack bottom they get one
I'll use this case to simplify how things work here......a lad has been taken to court for so many crimes I won't list them, he is cautioned over & over, he then gets an asbo, he breaks it, he has more conditions put on the asbo, he breaks them and more conditions are put on, and so it goes on, the lad is being sent a message that these conditions don't mean shit, because he is getting sent away with just a few more each time, so he carries on unpunished, he then goes to jail because he thinks the conditions don't mean anything and continues to misbehave, so he comes out of prison with conditions, these are called being on licence, he has to wear a tag and is set a curfew for 8pm to 8am, he breaks that curfew, he is told off, he breaks it again, he is told off again, he continures to break it until on the 5th time he is arrested and taken to court, now bear in mind the same lad has been told if he breaks it ONCE, that is his lot, by the 3rd or 4th time he realises that's just bullshit, he breaks it for a 6th time, why? Because there is no consequence! He has been sent the message that it is okay because he will only get told off, this has already be proved to him in his mind, they aren't going to do anything about it, they haven't done anything about it, why bother putting the tag in place in the first instance?
So is it fair to him when they arrest him and he is sent back to jail? Who is at fault here? Him for breaking his tag conditions or the powers that be for letting him think it is okay to break them 5 times over?
