That's all fine and good and I appreciate the thoughtfulness of the Scandinavians about this.
But there's a huge component missing to this - and that is the rights of the victims.
There are quite a number of people who have 'committed a crime' and really are at no risk of re-offending in the first place.
A Montreal doctor, in a fit of fury, murdered his wife and children. I believe - with some basic help and observation, it's entirely unlikely he'd do such a thing again. I don't think for a second that 'prison' or even the 'threat of prison' factors into his likelihood of recitivism.
So the 're-integration' thing to do for this doctor would just be a little time in a psych/hospital, then re-integration and observation/checking-in on him.
But what about the wife? The kids that were murdered? What about their rights as victims?
If you 'slander' someone - you might have to pay them $100K.
But if you 'murder' them - there's nobody to pay?
This is a real issue - and more real in Scandinavia.
I have a distant relative who is Danish - a rough and tumble guy who hangs out with bikers. Over at his place for dinner one day (in Denmark) - the guy sitting beside me (who seemed rather normal if a tiny bit thuggish) - was a murderer.
He spent four years in jail for murdering someone, and was now in a 'half way house' for a couple of years. That's it.
I don't doubt that maybe his situation is optimized for 'non recidivism' - but there are moral questions with this.
Four years in a really nice jail - with Internet, a 'instrument' room with instruments, a goddam mixing panel to make tracks (!), a gym, half decent food - etc. - is just wrong.
Imagine if your mother/family member was ruthlessly murdered by her landlord.
He does four years in an easy prison. No worries. His property, holdings intact. He comes back as if it didn't happen, with a little bit of 'checking in' form the government?
We cannot think of crime just as a matter of 'recidivism rates' - yes - those are important - but the moral implications are equally as important.
