Probation Officers in the Netherlands noticed an increase of ‘atypical’ clients: offenders convicted of cybercrime. “How do we deal with this new category of clients?”, is what they asked their policy advisors. Jelle van Triest set up the National Expertise Network Cybercrime for the Dutch Probation Service when he worked there as a Policy Advisor (he currently works as a Policy Advisor for the Dutch Ministry of Justice). In his National Expertise Network Cybercrime he combined scientific research, specialist expertise and daily practice. We asked him five questions about the network.
