An accused employee may not refuse to answer questions in an Internal Affairs interview and assert the right against self incrimination without fear that the agency may discipline the employee for insubordination. If the investigators determine prior to or during the course of an interview that an employee may be criminally charged, the employee must be advised of his or her constitutional Miranda rights. A statement given in an Internal Affairs interview or any information derived from the employee’s statement may not be used as evidence to support the criminal prosecution of that employee. However, statements given in the Internal Affairs interview may be used for purposes of impeachment if the employee is criminally charged and the employee’s testimony in the criminal proceeding is contrary to the Internal Affairs statement.
