This chapter examines the position and degree of accountability of senior police executives on integrity matters. This has been a neglected element in the corruption reform process in Australia. A case study from the Australian state of Victoria is presented. 'Conspicuously ethical leadership' is needed, and too often missing, within police organizations, it is argued. This is often visible in police whistle blower cases. Frequently, they are not dealt with in ways consistent with the goal of ethical leadership. Police executives need also to be accountable to democratically constituted police boards or commissions as a check on executive commitment to integrity.
