“Self-defense is a universal exception to the state’s monopoly on legitimate violence. State failure drives the self-defense doctrine through the imminence requirement. Private violence is justified where one faces an imminent threat of death or serious bodily harm to which the government cannot respond. The imminence requirement defines that space where the state, regardless of its motives and ambitions, simply cannot help. State failure within the window of imminence is a reality for everyone. But one might expect blacks to be particularly sensitive to it. The window of imminence is often larger in black neighborhoods where various challenges stretch public resources. Certainly state failure is less galling today. Under slavery, Black Codes, and Jim Crow, the state was often just another layer of threat, and reliance on the state for personal security was more obviously an absurd proposition. Today, the malevolent state is thankfully an anachronism. That makes it easier for those ensconced in government bureaucracies to urge reliance on the state and to ignore the continuing failure of government within the window of imminence. But it is sheer hubris for public officials to ignore the inherent limits on state power and claim that they can protect people within a space where that is impossible as a matter of simple physics.”
