From his telling essay, "Uptown: Fifth Avenue" written more than a half-century ago, by James Baldwin:
"It is hard, on the other hand, to blame the policeman, blank, good-natured, thoughtless, and insuperably innocent, for being such a perfect representative of the people he serves. He, too, believes in good intentions and is astounded and offended when they are not taken for the deed. He has never, himself, done anything for which to be hated--which of us has?--and yet he is facing, daily and nightly, people who would gladly see him dead, and he knows it. There is no way for him not to know it: there are few things under heaven more unnerving than the silent, accumulating hate of a people. He moves through Harlem, therefore, like an occupying soldier in a bitterly hostile country; which is precisely what, and where, he is, and is the reason he walks in two's and three's. And he is not the only one who knows why he is always in company: the people who are watching him know why, too. Any street meeting, sacred or secular, which he and his colleagues uneasily cover has as its explicit or implicit burden the cruelty and injustice of the white domination. And these days, of course, in terms increasingly vivid and jubilant, it speaks of the end of that domination."
