There is a particular kind of silence that falls over Nigerian public life when the powerful are implicated, however loosely, in the death of someone with no power at all. It is not the silence of ignorance, everyone in Abuja seems to have heard some version of what happened to Mary Habila. It is the silence of a system that has learned to wait things out: to let a press conference stand in for an inquest, a lawyer's letter stand in for a warrant, and public fatigue stand in for justice.
