The FBI selects future employees through stringent hiring standards. The rigorous recruiting, background, and selection process for special agents helps the FBI weed out potential problems, or at least keep them to a minimum. The FBI’s internal affairs department is called the Office of Professional Responsibility (OPR). When I was an active employee, OPR would issue a quarterly report of bad behavior and the punishment dealt out to the employee as a warning to all.
Bottom line, based on this book written by former FBI Agent Jerri Williams, I feel the FBI is one government agency that insists on high-quality employees, and actually HAS high-quality employees..
