Street Gangs and Drug Sales in Two Suburban Cities discusses the results of a study to determine the level of street gang involvement in drug sales arrests in two Los Angeles suburban cities from 1989 to 1991. Results are compared with those from an earlier study of gang involvement in cocaine sales based on arrest incidents in South Central Los Angeles between 1983 and 1985. Police departments that participated in this study also provide their views of the findings. Key findings include: The statistical connection between street gangs, drug sales, and violence was smaller than anticipated. Gang members were arrested in 27 percent of 1,563 cocaine sale arrest incidents occurring between 1989 and 1991 in two Los Angeles suburban cities.
