Report: DOJ, Native American cooperating in work on prosecutions WASHINGTON, May 30 (UPI) -- The Justice Department's prioritization of crime on American Indian land led to a greater commitment to law enforcement work in Indian Country, a report said. Overall caseloads increased annually from 1,091 cases filed in fiscal year 2009 to 1,677 in fiscal year 2012, representing a nearly 54 percent increase, the Justice Department report, "Indian Country Investigations and Prosecutions," released Thursday, said. The report shows a new level of partnering between the federal government and American Indian tribes, including an "unprecedented" level of collaboration with tribal law enforcement, the release said. Overall, a substantial majority of Indian Country criminal cases opened by U.S. attorney offices were prosecuted, the report said. "Across the country, U.S. attorneys have been focused on fighting crime in Indian Country and reinforcing the bond between federal and tribal law enforcement, which also strengthens the faith that people have in their criminal justice system," U.S. Attorney General Eric Holder said. This report on federal law enforcement efforts in Indian Country is beginning to show the fruits of this labor with an increase in Indian Country cases prosecuted in federal courts over the past three years, but we have more work to do. The report is based on data compiled from the case management system used by U.S. Attorney's Offices with Indian Country jurisdiction. Holder said the Justice Department would maintain its commitment to working with tribal partners "to build safe, sustainable, and healthy communities in American Indian and Alaska Native communities."
