From DutchNews.nl:
A ‘mass exchange’ of DNA profiles between the Netherlands and Belgium may have helped solve hundreds of crimes, Belgian media report on Thursday.
In total, 1,745 matches were found when crime scene DNA held in data banks in the two countries was compared. In 576 cases, DNA found at a crime scene in one country could be linked to someone who had been forced to give a sample in the other.

Belgium will also soon make DNA exchanges with German and French DNA banks.
Since 2005, everyone convicted of a crime punishable by four years or more in jail in the Netherlands must give a dna sample. This is kept on the data base for 20 years.
There’s no mention in this article of any privacy or human rights concerns. How would you feel if the U.S. shared your DNA with other countries for law enforcement purposes? I can see querying in particular cases, but mass exchange?
