In December 2010, the Bureau of Justice Assistance in the U.S. Department of Justice awarded a grant to the International Association of Chiefs of Police (IACP) to examine the impact of the Bureau of Alcohol, Tobacco, Firearms and Explosives (ATF) Interstate Trafficking Program (iTrafficking), launched in 2008, to promote a regional approach to firearms trafficking investigations. By assigning contractors to four key fusion centers in the Northeast region of the United States to analyze crime gun data, the ATF sought to develop an innovative, multi-state approach to reducing violent crime through shared resources and increased collaboration. Working with ATF contractors and fusion center personnel from those four pilot sites, the IACP conducted an extensive review of the development and implementation of the program.
