Across many public institutions, succession is rarely a simple matter of who is next in rank. In policing, that tension is especially sharp because hierarchy, command discipline and morale are not abstract ideas; they are the operating system of the institution. Nigeria has long wrestled with this problem in public debate: when an Inspector-General of Police leaves office, the next appointment may reflect presidential discretion, political confidence, regional balancing, reform ambition or crisis management, rather than strict seniority. The law itself gives the President significant latitude in appointing the IGP on the advice of the Police Council from among serving members of the force, and the Police Act also sets the four-year tenure framework that has itself become politically contested in recent years. The question is not whether discretion exists; it does. The real question is how that discretion is used, what it costs when overused, and whether the gains justify the institutional wear and tear.
