The UK currently maintains the largest DNA Database in the world and is encouraging other governments to implement similar systems in their respective countries. Using international organisations such as Interpol, participant governments will be able to share and exchange the DNA profiles of their citizens subject to vague legislative provisions, such as 'the interests of crime detection and prevention'.
The successful prosecution of a serial sex offender in 2004 led to strengthened calls for a more active use of the global DNA database operated by Interpol. Caroline Dickinson was 13 years old when she was raped and murdered in a hostel in Brittany whilst on a school trip in 1996, but it was not until 2004 that her killer was convicted. Early police investigations had not raised any significant leads but at the persistence of Caroline’s parents, the French police authorities changed their traditional operational practices and conducted the first mass DNA testing in France, taking over 3,500 samples. This did not however prove to be fruitful in assisting the capture of the perpetrator.
