Numb3rs Season 6 Episode 2

Don decided to hunt Fox down alone, but normally the FBI would employ no less than two men to capture an extremely dangerous target such as Fox, who is a former Navy SEAL and FBI instructor.

During the episode, the detectives make multiple references to "OPR." This stands for the Office of Professional Responsibility, more commonly known as Internal Affairs. They investigate any allegations of misconduct within the Federal Bureau of Investigation.
