The Port Arthur Police Department's Professional Standards Division is mandated to investigate allegations of misconduct against employees of the Port Arthur Police Department. The Internal Affairs Division has three purposes:
Protection of the Public -- The public has the right to receive fair, efficient, and impartial law enforcement. Any misconduct by department personnel must first be detected, then thoroughly investigated, and finally properly adjudicated to assure maintenance of these qualities.
Protection of the Department -- The Police Department is often judged and evaluated by the conduct of its employees. It is imperative that the whole organization not be criticized because of the misconduct of a few. An informed public must have confidence that its police department honestly and fairly investigates and adjudicates all allegations of misconduct against its employees.
Protection of the Employee -- Employees must be protected against false or misinformed allegations of misconduct.
