This one of Emma Goldman's essay from 1911 explores the what,why, how, and who of political violence. It feels relevant to share in the current climate.

TO ANALYZE the psychology of political violence is not only extremely difficult, but also very dangerous. If such acts are treated with understanding, one is immediately accused of eulogizing them. If, on the other hand, human sympathy is expressed with the Attentäter, one risks being considered a possible accomplice. Yet it is only intelligence and sympathy that can bring us closer to the source of human suffering, and teach us the ultimate way out of it.
