Police, as agents of the state, affect its legitimacy by their acts and the way they carry them out. They enjoy considerable powers and autonomy, in comparison with most public employees. Oddly, public administration studies almost ignore them. During the 1990s, the Sûreté du Québec experienced a number of problems of control and responsibility, not because of corruption but because of excess zeal, irresponsibility and sometimes incompetence. Several inquiries and studies, culminating with the massive Poitras Commission report of 1998, revealed a variety of problems, but many points in common. These studies show that while the SQ has known familiar problems rooted in police culture and the power of the police union, a whole range of measures could be pursued by the Department of Public Security and by the SQ to make it more open, more effective and more responsible. Several reforms now taking place could change the orgnizational culture of the Sûreté.
