"Tragedy happens - "tragic mistakes" happen - when men act according to their flawed natures, in fulfillment of their preordained destinies. The tragedy of the four killers of Amadou Diallo is that their deeds were made possible by their general preconceptions about black people and poor neighborhoods; by a theory of policing that encourages them to be rigid and punitive toward petty offenders; and by a social context in which the possession and use of firearms is so normative as to be almost beyond discussion. The tragedy of the street vendor Amadou Diallo is that he came as an innocent to the slaughter, made vulnerable by poverty and by the color of his skin. And the tragedy of America is that a nation which sees itself as leading the world toward a global future in which the American values of freedom and justice will be available for everyone fails so frequently and so badly to guarantee that freedom and that justice for so many people within its own frontiers."
