Corporal and Capital Punishment

The petition is entitled bring back the cane in schools and capital punistment for criminals as there is no discipline in this country any more and it will only get worse and the explanatory notes say

"The cane would stop the out of control kids and maybe cut crime in the future it's better than no discipline what so ever. Why do we keep people in person who will never change and keep causing good people pain and make them scared to go out at night."

There is a marvellous quote I'm thinking of:

"What is happening to our young people? They disrespect their elders, they disobey their parents. They ignore the law. They riot in the streets inflamed with wild notions. Their morals are decaying. What is to become of them?"

It is, of course, a quote from Plato. You know, the Greek philosopher from around 400BC. Apparently there's vast quantities of similar quotes in early Roman literature, too.
