Geektastic: We could also have US style chain gangs picking litter etc under armed guard.
A bit of public shame for these criminals might help.
From your posts it would seem you come from a generation where punishment, shaming, hard labour and bit of military service would "sort the buggers out."
However the evidence does not support such ideas.
You don't have to try very hard to find study after study which discusses the complexities of criminal behaviour and what leads to it - and the interventions that need to be implemented to get any real reduction in recidivism and a safer society as a result.
So yeah up to you ....... keep thinking the way you always have - or look for alternative ideas that will actually benefit us all - offenders included.
I'm 49. Whatever generation that makes me.
Executing the worst of them will make for a safer society but unfortunately we can't do that. Punishing them - by which I mean ideally inflicting shame and pain on them as a form of discouragement - would at least make them feel that they are being punished. I'm not really interested in benefiting offenders, more in disposing of them from society if possible. Some handy sub-Antarctic island penal colony might be an idea.
