The prosecutor has more control over life, liberty, and reputation than any other person in America…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. —Justice Robert Jackson
