The Netherlands is known as one of the pioneering countries adopting a whole-of-government approach to fighting organised crime. In 2012, the Dutch government launched a similar multi-agency approach to tackle outlaw motorcycle gangs (OMCGs). This paper provides a brief overview of the problem of OMCGs in the Netherlands and describes the different aspects of the Dutch whole-of-government approach. After reflecting on these efforts, we conclude that little is yet known about the effectiveness of this whole-of government approach to OMCG crime.
