But the validity of a doctrine does not depend on whose ox it gores. - Robert H. Jackson

Men are more often bribed by their loyalties and ambitions than by money.

There is a most important reason why the prosecutor should have, as nearly as possible, a detached and impartial view of all groups in his community. Law enforcement is not automatic. It isn't blind. One of the greatest difficulties of the position of prosecutor is that he must pick his cases, because no prosecutor can even investigate all of the eases in which he receives complaints. If the department of justice were to make even a pretense of reaching every probable violation of federal law, ten times its present staff would be inadequate. We know that no local police force can strictly enforce the traffic laws, or it would arrest half the driving population on any given morning, [sic!] What every prosecutor is practically required to do is to select the cases for prosecution and to select those in which the offense is the most flagrant, the public harm the greatest, and the proof the most certain.

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.
