As a result, 2,000 people are unemployed, and only 700 of them are able to work in other law enforcement agencies. The reason for the decrease in crime is related to the anti-crime measures implemented since 2004. The Minister of Justice of the Netherlands, Ard van der Stuur, said that although 240 prisoners were "imported" from Norway and held in their own prisons, The country's parliament reported that keeping half-empty prisons is harmful to the economy. The reasons for this decrease in crime are related to the changes in the law dealing with drug-related crimes, and the decision to force treatment instead of punishment, and the transition to a monitoring system using electronic bracelets for prisoners, and the fact that they are provided with the opportunity to live and work freely. A 2008 study found that electronic bracelets reduced crime by 50%.
