The organisational structure, social networks and criminal activities of outlaw motorcycle gangs: literature review

Outlaw motorcycle gangs (OMCGs) are often reported to be disproportionately involved in crime. Debate continues about the relationship between the organisational structure of these groups and the extent and types of criminal activities undertaken by group members. A systematic review of the existing literature was conducted to examine the organisational structures that underpin the criminal activity of OMCGs. The available empirical research, though scant, supports the notion that, at least in some clubs or chapters, the structure of OMCGs facilitates criminal activities by individuals or small cliques, sometimes in collaboration with non-members.

Criminal mobility of outlaw motorcycle gangs in Australia

The criminal mobility of outlaw motorcycle gang (OMCG) members presents a significant challenge to Australian governments and police. Examining patterns of mobility can help to better understand the opportunity structures that underpin offending by OMCGs and to drive national collaborative responses to these gangs. This study examines the prevalence and patterns of criminal mobility in a sample of almost 4,000 OMCG members in more than 400 chapters. Around one in 10 members showed evidence of criminal mobility over the long term, while more than one-third of chapters comprised criminally mobile members. Criminally mobile gang members were heavily concentrated in a small number of chapters. Patterns of criminal mobility primarily involve movements into east coast jurisdictions. New South Wales and Queensland emerged as the most common destinations for criminally mobile OMCG members.

The changing culture of outlaw motorcycle gangs in Australia

This study explores changes to the internal culture of a sample of Australian outlaw motorcycle gangs (OMCGs). We analysed data from 39 in-depth interviews with former OMCG members in Queensland to discern changes in recruitment practices, hierarchies and governance processes, as well as values, norms and relationships experienced and observed while members of an OMCG. Structurally, clubs changed little, although participants described how members were increasingly using the structures and systems of clubs for their own benefit. Changes were noted in recruitment practices, which were seen as increasingly geared towards enlisting violent, criminally-inclined men. There was also a perceived erosion of loyalty and camaraderie within OMCGs, with a shift towards younger, newer members who were seen as self-interested and financially motivated. These changes were contributing factors in decisions of many former members to disengage from OMCGs.

Effects of outlaw motorcycle gang membership and the support needs of former members

Drawing on interviews with 39 former members of outlaw motorcycle gangs (OMCGs), we identify consequences associated with leaving the club and the effects of membership experienced before and after leaving. This evidence is important in helping to inform efforts to promote and facilitate disengagement from clubs. While some members experienced adverse consequences from leaving the club, less hostile separations were not uncommon. Poor mental health, the breakdown of relationships with family and friends outside the club, and problems finding employment post-disengagement were common effects described by former members. Therapeutic interventions, access to stable employment, and the availability of peer and family support networks were common themes in the transition away from clubs. But, importantly, experiences of former members varied, highlighting the need for a flexible response.

Outlaw motorcycle gangs and their members’ crime: Examining the social organization of crime and its relationship to formal club hierarchy

In recent years, many European countries have taken far-reaching measures to combat the criminal activities of outlaw motorcycle gangs (OMCGs). Meanwhile, empirical research into the ways OMCGs are involved in and influence the crimes of their members is largely lacking. This study presents the main findings of research based on police files of cases that were filed against members of Dutch OMCGs. We apply a criminological scenario approach to analyse to what extent and in which ways OMCGs are involved in the crimes of their members. The results show that OMCG membership particularly plays an indirect role in the criminal behaviour of OMCG members. Board members, for example, give permission for criminal acts, regulate mutual relationships between members, non-members and rival OMCGs during conflict situations, and forbid (criminal) behaviour of members that is harmful to the OMCG. OMCGs function as a pool of co-offenders and as a market for criminal enterprises. Members also use the violent reputation of OMCGs in specific criminal activities. OMCGs are less frequently directly involved in crimes. Direct involvement of OMCGs is most apparent in organized inter-gang violence and violence against their own members.
