Initially, the police force reacted to ICAC with professional jealousy, suspiciousness, and resentment at being deprived of this investigative function. Since then, attitudes have changed and relations between ICAC and the police have improved markedly, as evidenced by police willingness to pass corruption reports directly to ICAC, the ready cooperation of police conducitng investigations, and joint ICAC/police action in conducting inquiries and making arrests. In addition to investigation and arrest, ICAC plays a role in corruption prevention during police officer training and through studies of police policies and procedures. In addition to identifying and providing remedies for opportunities for police corruption, such studies have proved valuable management audit exercises and have contributed to improved police performance. By assuring an independent and objective investigation of alleged police corruption, the ICAC has gained both police and public support and lowered the level of corrupt police activities.
