Under this grant from the Bureau of Justice Assistance, ILJ provided technical assistance to five demonstration sites: police departments in Tucson, Arizona; Atlanta, Georgia; Fort Wayne, Indiana; and prosecutors offices in New York County (Manhattan), New York, and Kings County (Brooklyn), New York. To develop model gang enforcement strategies, ILJ has drawn upon the lessons learned by the demonstration sites and the findings from a survey of over 175 police departments, serving mid-to-large size jurisdictions, on gang enforcement strategies and level of gang activity. ILJ completed a draft prototype model and operations manual for use by other jurisdictions seeking to address their gang problems.
