The Oklahoma State Bureau of Investigation (OSBI) patch depicts an Osage Indian warrior’s shield crossed by a peace pipe and an olive branch, derived from the Oklahoma state flag. An eagle, symbolizing vigilance, stands atop the shield, and the microscope and scales of justice on either side represent criminal investigation and criminal justice. The OSBI’s founding year is located beneath the seal.
