In todays edition of the major danish newspaper Berlingske Tidende there is an article about how the fine system is not working properly in Denmark. Since 2005 the fines citizens get for graffiti, vandalism and other minor offenses have been handled by the danish tax authority. And all they have done is sending out letter after letter with fines. If you didnt pay the fine, nothing happened. But now the unpaid fines will land you in jail, and about 4000 citizens seems to be going that way, just that small problem that the total capacity in danish jails is around 4000.
And the article is beautifully illustrated with this lovely photo from the DSB buff area.
