Gangs have been subjects of extensive empirical research since the 1920s. Scholarly interest in gangs was largely due to gang members’ increased likelihood of engaging in delinquent behavior. Gang members have been involved in criminal activities ranging from drug dealing to theft, property offenses, gun violence, and homicide. In the 1980s, there was nationwide concern about gangs as violent gang-related crimes increased and drew media attention. As a result, important legislation was implemented that made gang membership illegal. These policies were designed to curb gang involvement and de-escalate gang violence. The legislation included civil gang injunctions, the development of gang databases, and the formation and strengthening of gang task force units. Indeed, the policies resulted in an increase of gang unit officers focused on mitigating gang involvement and gang crime. Officer strategies focused on stopping, detaining, and arresting individuals who often fit certain stereotypes. Specifically, officers routinely based gang-related encounters on suspects’ race, age, clothing, gender, and geographic location, focusing mostly on young men of color in economically depressed neighborhoods. Perhaps unsurprisingly, a number of problems and concerns related to aggressive and biased police behavior surfaced, resulting in questionable outcomes of gang suppression. Research suggests that directed patrols and removing leadership might not be effective. Instead, alternate policies should include policing in conjunction with support from community-based nonprofit organizations and research that accounts for gang members’ experiences of law enforcement strategies.
