We granted certiorari, and in this Court the parties changed positions as nimbly as if dancing a quadrille. - Robert H. Jackson

The qualities of a good prosecutor are as elusive and as impossible to define as those which mark a gentleman. And those who need to be told would not understand it anyway. A sensitiveness to fair play and sportsmanship is perhaps the best protection against the abuse of power, and the citizen's safety lies in the prosecutor who tempers zeal with human kindness, who seeks truth and not victims, who serves the law and not factional purposes, and who approaches his task with humility.

He loved his profession, he had a real sense of dedication to the administration of justice, he held his head high as a lawyer, he rendered and exacted courtesy, honor and straightforwardness at the Bar. He respected the judicial office deeply, demanded the highest standards of competence and disinterestedness and dignity, despised all political use of or trifling with judicial power, and had an affectionate regard for every man who filled the exacting prescription of the just judge. The law to him was like a religion, and its practice was more than a means of support; it was a mission. He was not always popular in his community, but he was respected. Unpopular minorities and individuals often found in him their only mediator and advocate. He was too independent to court the populace - he thought of himself as a leader and lawgiver, not a mouthpiece.

Another delicate task is to distinguish between the federal and the local in law-enforcement activities. We must bear in mind that we are concerned only with the prosecution of acts which the congress has made federal offenses. Those acts we should prosecute regardless of local sentiment, regardless of whether it exposes lax local enforcement, regardless of whether it makes or breaks local politicians. [...] In spite of the temptation to divert our power to local conditions where they have become offensive to our sense of decency, the only long-term policy that will save federal justice from being discredited by entanglements with local politics is that it confine itself to strict and impartial enforcement of federal law, letting the chips fall in the community where they may. Just as there should be no permitting of local considerations to stop federal enforcement, so there should be no striving to enlarge our power over local affairs and no use of federal prosecutions to exert an indirect influence that would be unlawful if exerted directly.
