Ok lets atart by doing away with the idea of punishment, e.g. a negative response to some ones actions.
The idea of punishing the guilty is fundmanetal failure. We wait till the act has happened and then respond.
In medicine it would be seeing the Dr with a wart, and being told to come back when it's tumour.
In education it would be waiting till the adult is illiterate rather than teaching the child.
I would be more likely to say intensive therpay for kids who show early sociopathic tendencies, banning rap music that extoles a criminal tendency, and no automaitc right for incapable parents to bring up their own children.
Crime should be seen as the failure of society, not the individual.
If paedophiles, or serial killers could be stopped by gving them a £5.50 book token, shouldn't we start a collection?
