On the recommendation of the 9/11 Commission, Congress created the Office for State and Local Law Enforcement (OSLLE) in 2007 for two key purposes:
Lead the coordination of DHS-wide policies related to state, local, tribal, territorial, and campus law enforcement’s role in preventing, preparing for, protecting against, and responding to natural disasters, acts of terrorism, and other man-made disasters within the United States; and Serve as the primary liaison between DHS and non-Federal law enforcement agencies across the country.
