Although I don't really agree with violence, being a skinny little rat. I think as people said there are too many little buggers that think they can get away with anything. My dad used to get a clip round the ear from the local bobby. And he is a great, honest man.
I see it all the time working in young offenders prisons. That the little sods don't care about doing time coz its so damn easy.
I think sometimes a good "lesson" is a good idea to some of these trouble makers. It's a shame they get lost in all the red tape and human rights crap. Rather than being punished properly.
