Bring back hanging. It was stopped because a few mistakes were made. But now with DNA profilling can prove and pinpoint the exact assailant, then it is time to bring it back.
As for society in general, I think National Service would bring back a lot of the old fashioned values that have been forgotten. `Respect for others`. It would save this country a lot in unemployment and give some of these tear-aways some moral values. Its also a very good start in life. My 2 pence worth.
