Much of the ongoing concern about the presence of gangs and gang members in the community has to do with the association between street gangs and violence. Decades of research on street gangs demonstrates the complexity of the violent perpetration and victimization of gang members. Although the violence attributed to gang members reached its peak in the late 1980s and early 1990s, gang members continue to be disproportionately involved in violence, both as perpetrators and victims. Understanding gang violence requires careful consideration of the overlapping and intersecting relationships between violence and gang identity, victimization, perpetration, gender, and space. Violence plays an important role in the creation and maintenance of gang identity. Research on violence participation by gang members has demonstrated that gang violence can have both symbolic and instrumental purposes, and that this violence helps the gang build a collective identity and makes violence more normative. Despite some continued misconceptions about the role of female gang members and their presence in gangs, women make up a substantial portion of gang members, and any discussion of the relationship between gangs and violence must also consider the impact of gender on violence participation and victimization. Both male and female gang members are impacted by violence, but levels of participation and types of risk can vary by gender. The complex and gendered aspects of gang violence can make the prevention, intervention, and suppression of gang violence difficult tasks for law enforcement and policymakers. There are a range of perspectives on how best to reduce gang violence. Some researchers advocate early prevention programs to keep youth from joining gangs; others focus on ways to pull youth out of gangs at critical moments, such as when they enter emergency services. Other programs and policies are aimed at reducing gang violence that is ongoing in the community. These programs, such as Operation Ceasefire and Project Safe Neighborhoods, have utilized a focused deterrence framework to curb gang violence. All of these programs are aimed at reducing the amount of violence gang members participate in an attempt to minimize the risk of future violent victimization. Research on gang violence continues to grow and includes new avenues of research. The utilization of innovative methodologies, such as social network analysis, and new areas of research, such as examining the impact of social media on gang violence, continue to advance our knowledge of gang violence and its causes, correlates, and impact.
