Welcome to the Research & Analysis Unit of the Illinois Criminal Justice Information Authority

This site provides Illinois-specific criminal justice information and data in a way that's informative, interesting, and easy-to-navigate. Our goal is to offer a wide range of materials and resources that are useful to justice system practitioners, planners, researchers, students, and the general public.

This center is affiliated with and supported by the Justice Research and Statistics Association (JRSA), a national nonprofit organization that promotes collaboration and exchange of information among state SACs, and acts as a liaison between state agencies and the U.S. Department of Justice. Read more »

Collaborating to fight drug crime: Profile of the DuPage County Metropolitan Enforcement Group

April 19, 2012
Drug task forces were developed to more efficiently and effectively fight proliferation of illicit drugs. Local police have jurisdictional restraints making it difficult to combat drug markets extending through multiple cities, and counties (Smith, Novak, Frank, & Travis, 2000). Drug task forces work across jurisdictions and pool resources, knowledge, and personnel. MEGs and task forces are staffed by officers representing federal, state, county, and local police agencies. Drug task force officers work undercover, using confidential sources, to purchase drugs in order to gather the intelligence to make arrests (Reichert, 2012). | Download »
