The author of the parent comment seems not to understand recidivism in the United States if they were ever in prison at all. The Nordic example is leagues more potent than an anonymous anecdote.
Leave it to the typical HN comment on things like that to equate heaps of evidence with "I read X somewhere" and praise some anon anecdote over solid data.
Well, I'd like to remain anonymous for obvious reasons and will provide no proof of this assertion, but I'm actually that commenter's mother and they never went to jail.
