"In real life, people are too deferential and conformist in the face of government authority. They are all-too-willing to electrocute experimental subjects, gas Jews or bomb civilians when ordered to, and reluctant to stand up to political injustice. If anything, the dangerous thesis – the thesis that most people will mistakenly misapply – is that we should defer to government agents when they seem to act unjustly. Remember, self-defence against the state is about stopping an immediate injustice, not fixing broken rules.
Of course, strategic nonviolence is usually the most effective way to induce lasting social change. But we should not assume that strategic nonviolence of the sort that King practised always works alone. Two recent books – Charles Cobb Jr’s This Nonviolent Stuff’ll Get You Killed (2014) and Akinyele Omowale Umoja’s We Will Shoot Back (2013) – show that the later ‘nonviolent’ phase of US civil rights activism succeeded (in so far as it has) only because, in earlier phases, black people armed themselves and shot back in self-defence. Once murderous mobs and white police learned that black people would fight back, they turned to less violent forms of oppression, and black people in turn began using nonviolent tactics. Defensive subterfuge, deceit and violence are rarely first resorts, but that doesn’t mean they are never justified."
