An FBI employee shared confidential information with his girlfriend, who was a news reporter, then later threatened to release a sex tape the two had made. A supervisor watched pornographic videos in his office during work hours while satisfying himself." And an employee in a "leadership position" misused a government database to check on two friends who were exotic dancers and allowed them into an FBI office after hours. These are among confidential summaries of FBI disciplinary reports obtained by CNN, which describe misconduct by agency supervisors, agents and other employees over the last three years. The reports, compiled by the FBI's Office of Professional Responsibility, are e-mailed quarterly to FBI employees, but are not released to the public. And despite the bureau's very strict screening procedure for all prospective employees, the FBI confirms that about 325 to 350 employees a year receive some kind of discipline, ranging from a reprimand to suspension. About 30 employees each year are fired. "We do have a no-tolerance policy," FBI Assistant Director Candice Will told CNN. "We don't tolerate our employees engaging in misconduct. We expect them to behave pursuant to the standards of conduct imposed on all FBI employees." However, the internal summaries show that even with serious misconduct, employees can keep their job (names and locations of the employees are not listed in the reports).
