They have offices in Atlanta, Chicago, Dallas, DC (HQ really in VA) Kansas City, New York and San Francisco. In DC is also the SCERS and forensic document lab. FDIC OIG handles a wide variety of issues related to banking such as bank fraud, check fraud, mortgage fraud, cyber fraud, identity theft, phising, etc.. The OIG has about 125 employees TOTAL, including the audits staff and other civilians (not that many 1811's). Most cases are wored with the FBI and/or SIGTARP or the new mortgage OIG. Lots of travel.
They NEVER, EVER a non-1811. Everyone they bring on is already an experienced 1811. No take homes. 6c covered. Full LEO powers by statue. They have been around since at least 2008 when I finished FLECT and met the NY folks at a local task force meeting.
-In God we trust. All others, put your hands on the car and don't move.
