Get the old fashioned politicians back in. Ones who know what society means and what the definition of a 'cheeky little bugger' is and how to deal with them('yeah but times have changed'.. no they haven't we've all just gone slack and let kids get away with more, make them fear consequences of their actions properly and 'cheeky little buggers' is all we have to worry about again).
Bring back the cane and being able to smack kids. Force little shits to give their elders/teachers and police respect again or face getting a smack.
I honestly believe that's a large part of the problem. The youth of today gets away with faaar too much lip and lazyness without ANY fear of consequence and they are afforded lots of protection by the law.
If a little toerag is caught on the street carrying a blade, then send him to borstal for a week. If he is caught again, make it a month. Caught again send him to the army for a year.
Carry weapons to school. You're out. You are also going to borstal. What do you need a weapon in school for ffs!!!! "To protect myself"... who from!! little nobheads like yourself. If they are more scared of carrying a weapon because it has more severe consequences than taking a beating, then they won't carry a weapon simple as.
In the words of Chopper Reid. People of Britain need to 'Harden the fug aup'.
