"Police in Amsterdam are to be assigned their own recidivist criminal to monitor continuously in the hope of stopping the person committing further crimes. A trial of the scheme in several districts has proved so successful that it is being introduced across the capital. Police officers who take responsibility for a repeat offender are required to know at all times where the person is and what he or she is doing. The 'shadow' is alerted by email from police headquarters if the target is involved in crime or has been spotted elsewhere in the city. The officer is also informed by the prosecution service when the offender is released from custody." [Reoffending]
