The Office of Integrity and Quality Oversight, Investigations Quality Assurance Division conducted an oversight review of the National Protection and Programs Directorate (NPPD), Internal Affairs Division (IAD) from November 2014 to February 2015. The review covered IAD activity from October 1, 2011, to September 30, 2014 (fiscal years 2012 through 2014). We conducted this review as part of the planned periodic review of the Department of Homeland Security (DHS) component internal affairs offices by the DHS Office of Inspector General (OIG) in keeping with the oversight responsibilities mandated by the Inspector General Act of 1978, as amended. Generally, we found that inquiries conducted and overseen by the Internal Affairs Division were thorough and complete. Our review, however, raised serious concerns about NPPD’s authority to conduct criminal investigations. Additionally, we found that criminal investigators assigned to IAD did not meet the minimum legal requirement of spending at least 50 percent of their time on criminal investigative activity to earn Law Enforcement Availability Pay. Lastly, we found particular issues with the written policies and the overall management of inquiries.
